html - PHP page does not load when I try to show an error message
Get the solution ↓↓↓
I am trying to show a duplicate error on a form, but this function crashes the page and the page does not load. How can I configure file php.ini for this?
This is the function with that I am trying to show the error messages on the form page:
public function getError($error) {
if(!in_array($error, $this->errorArray)) {
$error = "";
}
return "<span class='errorMessage'>$error</span>";
}
This is the function which I am trying to use to get the error in the array:
private function validateEmails($em) {
$checkEmailQuery = mysqli_query($this->con,"SELECT email FROM member_forms WHERE email='$em'");
if(mysqli_num_rows($checkEmailQuery) != 0) {
array_push($this->errorArray, Strings::$emExists);
return;
}
}
These functions double-check with the database and if an error occurs,<?php echo $account->getError(Strings::$emExists); ?> should display it, but it does not and the page doesn't load.
When the error occurs, it goes until the error, but it does not render anything and the body of the HTML page goes empty

Answer
Solution:
I have used that code you posted works totally fine on my local host. Have you checked the server used on your new hosting?
If it's different, then the same code might not work as expected on another server. There are several factors affecting that. Click here to get tips on that.
You can also use the phpinfo() function. It might help in further debugging.

Solution:
I'm pretty sure that this code should fix this error:
if (isset($_POST['Update'])) {
/* a bunch of code to insert into the DB */
// if inserted echo the following messges
if ($r) {
echo "<script> alert('Saved')</script>";
}else{
echo "<b>Oops! we have an issu </b>";
}
}
