php错误没有进入catch,php – 致命错误：没有try / catch块的未捕获异常

我正在尝试在表单字段为空时以及插入查询不成功时抛出异常.我已经看到有人在不使用try / catch块而不包含Exceptions类之前抛出异常.有谁知道我会怎么做？

当我没有填写所有字段时,这是我得到的错误：

致命错误：未捕获的异常“异常”,消息为“错误：以下字段为空 – 标题,电话号码,电子邮件,”在第94行的/vagrant/web/Assignment4/Person.php中例外：错误：以下字段为空 – 标题,电话号码,电子邮件,在第94行的/vagrant/web/Assignment4/Person.php中调用堆栈：0.0014 638168 1. {main}()/ vagrant/web/Assignment4/Form.php:0 0.0172 698568 2. Person-> insert()/ vagrant/web/Assignment4/Form.php:179

public function insert()

{

//Storing required $_POST array fields in variable for isset function

$errorArray = array();

$expectedValues = array(

"firstName" => "First Name",

"lastName" => "Last Name",

"title" => "Title",

"office" => "Office",

"phoneNumber" => "Phone Number",

"email" => "Email",

);

//Checking to see if all fields are filled in

foreach ($expectedValues as $field => $humanName) {

if (empty($_POST[$field])) {

$errorArray[] = $humanName . ", ";

}

}

if (count($errorArray) > 0) {

throw new Exception("Error: The following fields are empty- " .implode(' ', $errorArray));

}

else{

//If they are, insert them into the Perosn table

$insert = $this-> doQuery("INSERT INTO Person

VALUES(

'$_POST[firstName]',

'$_POST[lastName]',

'$_POST[title]',

'$_POST[office]',

'$_POST[phoneNumber]',

'$_POST[email]')");

//If insert query is successful, return true

if ($insert === true){

echo "

";

return true;

}

//If not, throw an exception

/* else{

throw new Exception

("

");

}

try{

$insert == true;

}

catch (Exception $x){

echo $x->getMessage;
