登陆不上原因,在使用wampserver环境后,有些设置需要修改,
此时需要修改\system\libraries\Form_validation.php页面,需要改这个方法,这个是修改之后的方法:
public function run($group = '')
{
// Do we even have any data to process? Mm?
if (count($_POST) == 0)
{
return FALSE;
}
// Does the _field_data array containing the validation rules exist?
// If not, we look to see if they were assigned via a config file
/*if (count($this->_field_data) == 0)
{
// No validation rules? We're done...
if (count($this->_config_rules) == 0)
{
return FALSE;
}
// Is there a validation rule for the particular URI being accessed?
$uri = ($group == '') ? trim($this->CI->uri->ruri_string(), '/') : $group;
if ($uri != '' AND isset($this->_config_rules[$uri]))
{
$this->set_rules($this->_config_rules[$uri]);
}
else
{
$this->set_rules($this->_config_rules);
}
// We're we able to set the rules correctly?
if (count($this->_field_data) == 0)
{
log_message('debug', "Unable to find validation rules");
return FALSE;
}
}*/
// Load the language file containing error messages
$this->CI->lang->load('form_validation');
// Cycle through the rules for each field, match the
// corresponding $_POST item and test for errors
foreach ($this->_field_data as $field => $row)
{
// Fetch the data from the corresponding $_POST array and cache it in the _field_data array.
// Depending on whether the field name is an array or a string will determine where we get it from.
if ($row['is_array'] == TRUE)
{
$this->_field_data[$field]['postdata'] = $this->_reduce_array($_POST, $row['keys']);
}
else
{
if (isset($_POST[$field]) AND $_POST[$field] != "")
{
$this->_field_data[$field]['postdata'] = $_POST[$field];
}
}
$this->_execute($row, explode('|', $row['rules']), $this->_field_data[$field]['postdata']);
}
// Did we end up with any errors?
$total_errors = count($this->_error_array);
if ($total_errors > 0)
{
$this->_safe_form_data = TRUE;
}
// Now we need to re-set the POST data with the new, processed data
$this->_reset_post_array();
// No errors, validation passes!
if ($total_errors == 0)
{
return TRUE;
}
// Validation fails
return FALSE;
}
当设置了另一个管理员时,发现登陆后,页面内什么也没有,此时我们要修改这个地方,在控制器里面的构造函数
function admin_test() {
header ( "Cache-Control: no-cache, must-revalidate" );
header ( "Pragma: no-cache" );
parent::__construct();
$this->load->model ( 'admin/admin_test_model' );
$this->load->helper ( array ('form', 'url' ) );
/*if ($this->session->userdata ( 'admin_user_name' ) != 'admin') {
ajaxReturn ( "只有admin可以操作此模块!" );
}*/
}
