<think>We are going
to implement a selective checkout feature for WooCommerce using the Woodmart theme.
Steps:
1. Add checkboxes
to each cart item in the cart page.
2. Use JavaScript
to handle the checkbox selections and update the cart
total
to reflect only the selected items.
3. When the user proceeds
to checkout, we need
to ensure that only the selected items are included in the
order.
However, note that WooCommerce doesn't natively support partial checkout. Therefore, we have
to:
a) Either remove the unselected items from the cart when proceeding
to checkout (but then the user might lose those items).
b) Or, create a temporary cart with only the selected items and then redirect
to checkout with that cart.
Approach (a) is simpler but has the downside of removing items from the cart. We can res
tore them if the user comes back? Not ideal.
Approach (b) is more complex but user
-friendly. We can use session
to s
tore the original cart, then create a temporary cart with selected items and proceed
to checkout. After checkout, we can res
tore the original cart? But note: the user might not come back.
Alternatively, we can use the following approach:
1. On the cart page, when the user selects some items and clicks "Proceed
to Checkout", we intercept the click.
2. We send an AJAX request
to the server with the selected product keys (or cart item keys).
3. On the server, we create a new cart in the session (or temporary cart) that contains only the selected items.
4. Then, we redirect the user
to the checkout page with the temporary cart.
However, this approach might be complex because we have
to manage temporary carts and then merge back after checkout? But what if the user abandons checkout? We have
to clean up.
Alternatively, we can use the following simpler method:
We can use a cus
tom field in the cart item
to mark it as selected or not. Then, during the checkout
process, we remove the unselected items. But note: the cart page would still s
how all items until the next page load.
But the requirement is
to have the cart page s
how the
total for selected items only? And then when they go
to checkout, only selected items are there.
We'll break it down:
Step 1: Add checkboxes
to the cart items in the cart page.
We can override the WooCommerce cart template. Since we are using Woodmart, we should create a child theme and override the template.
Template
to override: `woocommerce/cart/cart.php` or more specifically, the item row. In Woodmart, the cart item template might be located in the theme's `woocommerce` folder.
Alternatively, we can use hooks. We'll use the hook `woocommerce_after_cart_item_name`
to add a checkbox.
Step 2: Update the cart
total when checkboxes are checked/unchecked.
We'll use JavaScript
to calculate the
total of selected items and update the displayed
total.
However, note that the actual cart
total in WooCommerce remains unchanged until we update the cart. We don't want
to update the cart until the user explicitly does so (like clicking "Update Cart") because removing items would require a page reload.
But we don't want
to remove items from the cart until they proceed
to checkout. So we are just s
howing a "virtual"
total for the selected items.
Step 3: When the user clicks "Proceed
to Checkout", we need
to remove the unselected items from the cart.
We can do this by:
- Intercepting the "Proceed
to Checkout" but
ton click.
- Collecting the keys of the unselected cart items.
- Sending an AJAX request
to remove those items from the cart.
- Then redirecting
to checkout.
But note: if the user then goes back
to the cart, the items are gone. We can s
tore the removed items in a session and res
tore them if they come back? That might be complex.
Alternatively, we can use a different approach: when the user clicks "Proceed
to Checkout", we create a temporary
order with only the selected items and then redirect
to checkout for that temporary
order? That's not standard.
Given the complexity, I propose a simpler approach that might meet the requirement:
We'll add a new but
ton next
to "Proceed
to Checkout" that says "Checkout Selected Items". When clicked, we will:
1. Use JavaScript
to collect the cart item keys of the selected items.
2. Then, set a cookie or sessionS
torage with these keys.
3. Redirect the user
to a cus
tom URL that triggers a PHP function
to remove the unselected items from the cart.
But then, after checkout, we need
to res
tore the cart? Or if the user cancels? We can s
tore the entire cart in a session and then res
tore it after checkout or when returning
to the cart.
However, this is a multi
-step
process and might be error
-prone.
Alternatively, we can use the following method:
- On the cart page, we have the checkboxes.
- We add a but
ton "Update Cart and Checkout Selected" that does:
* Update the cart: remove the unselected items and then redirect
to checkout.
But then the user loses the unselected items? We can s
tore them in a session and then if they come back
to the cart, we res
tore.
How to s
tore the entire cart in a session? We can use `WC()
->session`
to s
tore the full cart when they remove items for checkout.
Steps:
a) When the user clicks "Checkout Selected", we s
tore the current cart in a session variable (as an array of cart contents).
b) Then, we remove the unselected items and redirect
to checkout.
c) On returning
to the cart (if they cancel the
order), we check if there is a s
tored cart and res
tore it.
But note: what if they complete the
order? Then we should clear the s
tored cart.
We can set a flag in the session
to know when
to res
tore.
This is complex but doable.
Given the complexity and the fact that this is a cus
tom requirement, we'll break it in
to parts.
Let's start with the first part: adding checkboxes and updating the displayed
total without actually updating the cart.
Implementation Plan:
Part 1: Add Checkboxes
to Cart Items
We'll use the hook `woocommerce_after_cart_item_name`
to add a checkbox. But note: this hook is inside the table row and might not be the best place. Alternatively, we can use `woocommerce_cart_item_name` but that would be before the product name. We can also use `woocommerce_cart_item_sub
total`
to add after the price? Or we can override the template.
Since Woodmart is a theme, we should look for the template that renders the cart item. In Woodmart, the cart template is located in: `wp
-content/themes/woodmart/woocommerce/cart/`
We are going
to copy the relevant template
to our child theme and then modify it.
The template for cart items is: `cart
-item.php`
We'll add a checkbox at the beginning of the cart item row.
Example:
In `cart
-item.php`, after the opening `<tr>` and before the first `<td>`, we can add:
```php
<td class="product
-select">
<input type="checkbox" name="cart_item_selected[]" value="<?php echo esc_attr( $cart_item_key ); ?>" checked />
</td>
```
Then, we need
to adjust the table headers
to include a "Select" column.
We also need
to override `cart.php`
to add the header for the new column.
Alternatively, we can use JavaScript
to add the checkboxes without overriding templates? But that might be less reliable.
We'll go with overriding the template.
Steps for template override:
- Create a child theme if not already done.
- Copy `woodmart/woocommerce/cart/cart.php`
to `child
-theme/woocommerce/cart/cart.php`
- Copy `woodmart/woocommerce/cart/cart
-item.php`
to `child
-theme/woocommerce/cart/cart
-item.php`
In `cart.php`:
Find the table header (`<thead>`) and add a new `<th>` for "Select" at the beginning.
Example:
<thead>
<tr>
<th class="product
-select"><?php esc_html_e( 'Select', 'woocommerce' ); ?></th>
... existing headers ...
</tr>
</thead>
In `cart
-item.php`:
Add a new `<td>` at the beginning of the row with the checkbox.
Part 2: JavaScript
to update the displayed
total for selected items.
We'll add a script that:
- Listens
to changes on the checkboxes.
- For each checked item, it adds the item's sub
total
to the
total.
- Updates a display element with the new
total.
But note: the cart page already s
hows the cart
total. We want
to s
how two
totals: one for the entire cart and one for the selected items? Or replace the
total with the selected
total? We'll add a new row for "Selected
Total".
We can add a row in the cart
totals table for selected items.
We'll use a hook
to add a row after the cart
totals table.
Hook: `woocommerce_cart_
totals_after_
order_
total`
But we don't want
to update the actual cart
totals, only display a virtual
total.
Alternatively, we can add a new table above or below the cart that s
hows the selected
total and a but
ton
to checkout selected.
We'll add:
<tr class="selected
-total">
<th><?php esc_html_e( 'Selected
Total', 'woocommerce' ); ?></th>
<td data
-title="<?php esc_attr_e( 'Selected
Total', 'woocommerce' ); ?>">
<span class="selected
-total
-amount"><?php wc_cart_
totals_selected_
total_html(); ?></span>
</td>
</tr>
But we don't have such function. We'll create a cus
tom function
to calculate the selected
total and then update it via JavaScript.
We'll also add a but
ton for "Proceed
to Checkout (Selected Items)".
We'll put this but
ton next
to the existing checkout but
ton.
Steps:
- In `cart.php`, we'll add a new row in the cart actions for our cus
tom but
ton.
Alternatively, we can add the but
ton via JavaScript.
Let's write the JavaScript:
We'll calculate the selected
total by iterating over the checked checkboxes and summing the sub
total of each.
How to get the sub
total for an item? We can s
tore the sub
total in a data attribute on the row or on the checkbox.
In `cart
-item.php`, when rendering the item row, we can add a data attribute
to the row with the item's sub
total.
<tr class="woocommerce
-cart
-form__cart
-item" data
-item
-key="<?php echo esc_attr( $cart_item_key ); ?>" data
-item
-sub
total="<?php echo esc_attr( $cart_item['line_sub
total'] ); ?>">
Then, in JavaScript:
$('input[name="cart_item_selected[]"]').change(function() {
var selected
Total = 0;
$('input[name="cart_item_selected[]"]:checked').each(function() {
var itemKey = $(this).val();
var row = $(this).closest('tr');
var sub
total = parseFloat(row.data('item
-sub
total'));
selected
Total += sub
total;
});
// Update the selected
total display
$('.selected
-total
-amount').text(selected
Total.
toFixed(2));
});
But note: the sub
total might be displayed including tax or excluding tax? We are using the line sub
total which is without tax by default. We should use the same as the cart
total display.
The cart
total row in the table s
hows the
total including tax? It depends on the tax settings.
We can use the same method as the cart
total row: `wc_cart_
totals_
order_
total_html` uses the
total including tax if set.
We might need
to calculate tax? This could get complicated.
Alternatively, we can use the displayed sub
total for the item. We can get the value from the sub
total cell.
In the row, there is a cell with class `product
-sub
total` that has the formatted sub
total. We can parse that.
Example:
var sub
totalText = row.find('.product
-sub
total .amount').text();
var sub
total = parseFloat(sub
totalText.replace(/[^0
-9.,]/g, '').replace(',', '.'));
But this is fragile and might break with different currency formats.
We can s
tore the raw sub
total (without formatting) in a data attribute and then format it on the frontend? But we have
to consider the same formatting as WooCommerce.
Alternatively, we can use the data attribute and then format the number
to match the shop's currency.
We'll get the raw sub
total (without tax) and then if the shop displays prices including tax, we need
to add the tax?
This is getting
too complex.
Let's change our approach: we don't need
to recalculate the
total with tax because the cart
total row already includes tax. We are only interested in the line
total without tax? But the cart
total row is the sum of line
totals plus taxes and fees.
We can avoid this by not s
howing the tax breakdown and just s
howing the same as the cart
total but for selected items? That would require recalculating the entire cart for selected items including tax, which is not trivial.
Given the complexity, we might want
to avoid this and instead only update the
total when the user actually proceeds
to checkout? Or we can do an AJAX call
to the server
to calculate the selected
total including tax? But that would be heavy.
Alternatively, we can s
how the sub
total without tax and then a note that tax will be added at checkout? That might be acceptable.
We'll go with the line sub
total without tax for the selected
total display.
Then, in the selected
total row, we can display it as "Selected Sub
total" and then note that tax will be added.
We'll change the label
to "Selected Sub
total".
And then when the user proceeds
to checkout, they will see the actual
total including tax on the checkout page.
Part 3: Checkout for selected items.
We'll add a but
ton:
<but
ton type="but
ton" id="checkout
-selected">Proceed
to Checkout (Selected Items)</but
ton>
We'll intercept the click on this but
ton.
Steps:
$('#checkout
-selected').click(function() {
// Collect the keys of the selected items
var selectedKeys = [];
$('input[name="cart_item_selected[]"]:checked').each(function() {
selectedKeys.push($(this).val());
});
// S
tore the selected keys in a form and submit or use AJAX
// We are going
to submit a form that will remove the unselected items and then redirect
to checkout.
// We can set the selected keys in a hidden field and then submit a form.
// But note: we have
to remove the unselected items from the cart.
// We can create a form that posts
to the cart page with the action
to remove unselected items.
// We'll create a hidden form.
// Create a form
var form = $('<form>', {
action: '<?php echo esc_url( wc_get_cart_url() ); ?>',
method: 'post'
});
// Add the selected keys as hidden fields
$.each(selectedKeys, function(index, key) {
form.append($('<input>', {
type: 'hidden',
name: 'selected_items[]',
value: key
}));
});
// Add a nonce for security? We'll have
to generate one in PHP and pass
to JS.
// We'll create a nonce for our action and add it as a hidden field.
form.append($('<input>', {
type: 'hidden',
name: 'checkout_selected_nonce',
value: '<?php echo wp_create_nonce( "checkout
-selected" ); ?>'
}));
// Also, we need
to tell the server
to remove the unselected items and then redirect
to checkout.
form.append($('<input>', {
type: 'hidden',
name: 'action',
value: 'checkout_selected'
}));
$('body').append(form);
form.submit();
});
Then, on the server, we handle the form submission:
add_action('template_redirect', 'handle_checkout_selected');
function handle_checkout_selected() {
if (isset($_POST['action']) && $_POST['action'] === 'checkout_selected') {
// Verify nonce
if (!isset($_POST['checkout_selected_nonce']) || !wp_verify_nonce($_POST['checkout_selected_nonce'], 'checkout
-selected')) {
wc_add_notice('Invalid request.', 'error');
return;
}
$selected_keys = isset($_POST['selected_items']) ? $_POST['selected_items'] : array();
// S
tore the current cart in the session so we can res
tore it later
$cart = WC()
->cart
->get_cart();
WC()
->session
->set('checkout_selected_original_cart', $cart);
// Remove the items that are not in the selected keys
foreach ($cart as $cart_item_key => $cart_item) {
if (!in_array($cart_item_key, $selected_keys)) {
WC()
->cart
->remove_cart_item($cart_item_key);
}
}
// Now, redirect
to checkout
wp_safe_redirect(wc_get_checkout_url());
exit;
}
}
Then, we need
to res
tore the cart if the user comes back without completing the
order? We can do that on the cart page.
add_action('wp_loaded', 'res
tore_original_cart');
function res
tore_original_cart() {
// If we are on the cart page and there is a s
tored cart, res
tore it
if (is_cart() && ($original_cart = WC()
->session
->get('checkout_selected_original_cart'))) {
// Check if the current cart is empty? Or we can always res
tore?
// We want
to res
tore only if the user hasn't added new items?
// We'll res
tore the original cart and then remove the s
tored cart.
WC()
->cart
->cart_contents = $original_cart;
WC()
->cart
->calculate_
totals();
WC()
->session
->set('checkout_selected_original_cart', null);
}
}
But note: what if the user completes the
order? Then we don't want
to res
tore. We can clear the s
tored cart on the thankyou page.
add_action('woocommerce_thankyou', 'clear_original_cart');
function clear_original_cart() {
WC()
->session
->set('checkout_selected_original_cart', null);
}
However, if the user abandons checkout and goes back
to the cart, we res
tore. But if they go
to the shop and add more items, we should not res
tore? We can set a flag.
We'll only res
tore the cart if the s
tored cart exists and the current cart is empty? Or we can res
tore only once.
We'll res
tore only when the user comes back
to the cart page and the s
tored cart exists.
But note: if the user adds items after res
toring, we don't want
to res
tore again. So we clear the s
tored cart when we res
tore.
We are setting the s
tored cart
to null after res
tore.
This should work.
However, there is a caveat: if the user goes directly
to the checkout page and then back
to cart, we res
tore. But if they go
to the shop and then cart, we res
tore? That might be acceptable.
Also, what if the user has two tabs? We are s
toring the cart in the session. It might be overwritten.
This solution is a bit fragile but should work for most cases.
We'll code accordingly.
Summary of Steps:
Part 1: Templates
- Override `cart.php` and `cart
-item.php`
to add the select column.
Part 2: JavaScript for selected
total display and but
ton click.
Part 3: PHP
to handle the form submission for selected checkout and res
tore the cart.
Let's write the code accordingly.
Note: This is a simplified version and might need adjustments for the Woodmart theme.
We'll start with the template overrides.
Due
to the complexity and length, we'll break the code in
to sections.
Step
-by
-step code:
Step 1: Override cart.php and cart
-item.php in child theme.
Step 2: Modify cart.php
to add the header column.
Step 3: Modify cart
-item.php
to add the checkbox in a new column.
Step 4: Enqueue a JavaScript file for the cart page.
Step 5: Add the selected
total row and the cus
tom but
ton in cart.php.
Step 6: Write the JavaScript for updating the selected
total and handling the but
ton click.
Step 7: Write the PHP functions for handling the form submission and res
toring the cart.
Let's write the code.
Note: We are using hooks and filters in functions.php of the child theme.
Due
to the complexity, we'll provide the code in parts.
IMPORTANT: This is a cus
tom solution and might require debugging and adjustments for your specific setup.
Let's proceed.</think>
To implement a selective checkout with checkboxes in your WooCommerce/Woodmart cart page, follow this comprehensive solution. This approach uses a combination of template overrides, JavaScript, and WooCommerce hooks.
### Step 1: Add Checkboxes
to Cart Items
Override the Woodmart cart template by creating these files in your child theme:
`wp
-content/themes/child
-theme/woocommerce/cart/cart.php`
`wp
-content/themes/child
-theme/woocommerce/cart/cart
-item.php`
**Modified `cart.php` (Add header column):**
```php
<thead>
<tr>
<th class="product
-select"><?php esc_html_e('Select', 'woocommerce'); ?></th>
<!
-- Keep existing headers
-->
</tr>
</thead>
```
**Modified `cart
-item.php` (Add checkbox):**
```php
<tr class="woocommerce
-cart
-form__cart
-item">
<td class="product
-select">
<input type="checkbox"
class="cart
-item
-selec
tor"
name="cart_item_selected[<?php echo esc_attr($cart_item_key); ?>]"
checked
data
-item
-key="<?php echo esc_attr($cart_item_key); ?>"
data
-price="<?php echo esc_attr($product
->get_price()); ?>">
</td>
<!
-- Keep existing item markup
-->
</tr>
```
### Step 2: Add Selected
Total Section
Insert this before the checkout but
ton in `cart.php`:
```php
<div class="selected
-items
-total">
<h3><?php esc_html_e('Selected Items
Total', 'your
-textdomain'); ?></h3>
<p>
<strong><?php esc_html_e('Sub
total:', 'woocommerce'); ?></strong>
<span id="selected
-sub
total"><?php wc_cart_
totals_sub
total_html(); ?></span>
</p>
<but
ton type="but
ton" id="proceed
-selected
-checkout" class="but
ton alt">
<?php esc_html_e('Checkout Selected Items', 'woocommerce'); ?>
</but
ton>
</div>
```
### Step 3: Add JavaScript Logic
Create `js/cus
tom
-cart.js` in your child theme and enqueue it:
**JavaScript File:**
```javascript
jQuery(function($) {
// Update selected
total when checkboxes change
$('.cart
-item
-selec
tor').change(function() {
let selected
Total = 0;
$('.cart
-item
-selec
tor:checked').each(function() {
const price = parseFloat($(this).data('price'));
const qty = parseFloat($(this).closest('tr').find('.qty').val());
selected
Total += price * qty;
});
$('#selected
-sub
total').html('$' + selected
Total.
toFixed(2));
});
// Handle selected checkout
$('#proceed
-selected
-checkout').click(function() {
const selectedItems = [];
$('.cart
-item
-selec
tor:checked').each(function() {
selectedItems.push($(this).data('item
-key'));
});
// Send
to server via AJAX
$.ajax({
type: 'POST',
url: wc_cart_params.ajax_url,
data: {
action: '
process_selected_checkout',
selected_items: selectedItems,
security: wc_cart_params.cart_nonce
},
success: function(response) {
window.location.href = wc_cart_params.checkout_url;
}
});
});
});
```
### Step 4: PHP Backend Handling
Add this
to your child theme's `functions.php`:
```php
//
Process selected checkout
add_action('wp_ajax_
process_selected_checkout', '
process_selected_checkout');
add_action('wp_ajax_nopriv_
process_selected_checkout', '
process_selected_checkout');
function
process_selected_checkout() {
check_ajax_referer('woocommerce
-cart', 'security');
if (!empty($_POST['selected_items'])) {
WC()
->session
->set('selected_checkout_items', $_POST['selected_items']);
wp_send_json_success();
}
wp_send_json_error();
}
// Filter cart contents before checkout
add_filter('woocommerce_get_cart_contents', 'filter_cart_contents_for_checkout');
function filter_cart_contents_for_checkout($cart_contents) {
if (is_checkout() && $selected_items = WC()
->session
->get('selected_checkout_items')) {
foreach ($cart_contents as $key => $item) {
if (!in_array($key, $selected_items)) {
unset($cart_contents[$key]);
}
}
WC()
->session
->__unset('selected_checkout_items');
}
return $cart_contents;
}
```
### Step 5: Enqueue
Scripts
Add this
to `functions.php`:
```php
add_action('wp_enqueue_
scripts', 'enqueue_cart_
scripts');
function enqueue_cart_
scripts() {
if (is_cart()) {
wp_enqueue_script('cus
tom
-cart',
get_stylesheet_direc
tory_uri() . '/js/cus
tom
-cart.js',
array('jquery', 'wc
-cart'),
'1.0',
true
);
wp_localize_script('cus
tom
-cart', 'wc_cart_params', array(
'ajax_url' => admin_url('admin
-ajax.php'),
'cart_nonce' => wp_create_nonce('woocommerce
-cart'),
'checkout_url' => wc_get_checkout_url()
));
}
}
```
### Key Features Explained:
1. **Checkbox Integration**
Added
to each cart item with price data attributes for calculations.
2. **Dynamic
Total Calculation**
JavaScript recalculates sub
total when checkboxes change.
3. **AJAX
Processing**
Selected items are sent
to server before checkout redirection.
4. **Session
-Based Filtering**
Uses WooCommerce sessions
to temporarily modify cart contents only during checkout.
5. **Themes Compatibility**
Uses proper template overrides
to maintain Woodmart styling.
