Unable to load the "PHP Email Form" Library - php

Question

For some reason, my PHP Form doesn't work, when someone presses send message button this error pops out "Unable to load the "PHP Email Form" Library". I don't know what the problem is.
This is contact.php
<?php
$receiving_email_address = 'myemailadress';
if( file_exists($php_email_form = '../assets/vendor/php-email-form/php-email-form.php' )) {
include( $php_email_form );
} else {
die( 'Coming Soon!');
}
$contact = new PHP_Email_Form;
$contact->ajax = true;
$contact->to = $receiving_email_address;
$contact->from_name = $_POST['name'];
$contact->from_email = $_POST['email'];
$contact->subject = $_POST['subject'];
// Uncomment below code if you want to use SMTP to send emails. You need to enter your correct SMTP credentials
/*
$contact->smtp = array(
'host' => 'example.com',
'username' => 'example',
'password' => 'pass',
'port' => '587'
);
*/
$contact->add_message( $_POST['name'], 'From');
$contact->add_message( $_POST['email'], 'Email');
$contact->add_message( $_POST['message'], 'Message', 10);
echo $contact->send();
?>
This is index.html
<div class="form">
<form action="forms/contact.php" method="post" role="form" class="php-email-form">
<div class="row">
<div class="form-group col-md-6">
<input type="text" name="name" class="form-control" id="name" placeholder="Your Name" required>
</div>
<div class="form-group col-md-6 mt-3 mt-md-0">
<input type="email" class="form-control" name="email" id="email" placeholder="Your Email" required>
</div>
</div>
<div class="form-group mt-3">
<input type="text" class="form-control" name="subject" id="subject" placeholder="Subject" required>
</div>
<div class="form-group mt-3">
<textarea class="form-control" name="message" rows="5" placeholder="Message" required></textarea>
</div>
<div class="my-3">
<div class="loading">Loading</div>
<div class="error-message"></div>
<div class="sent-message">Your message has been sent. Thank you!</div>
</div>
<div class="text-center"><button type="submit">Send Message</button></div>
</form>
</div>
Anf for some reason some kind of a error log file came up in the folder that says:
[19-Nov-2021 13:49:31 UTC] PHP Fatal error: Uncaught Error: Class 'PHP_Email_Form' not found in /home/domain/public_html/forms/contact.php:16
Stack trace:

[19-Nov-2021 13:49:32 UTC] PHP Fatal error: Uncaught Error: Class 'PHP_Email_Form' not found in /home/domain/public_html/forms/contact.php:16
Stack trace:
#0 {main}
thrown in /home/domain/public_html/forms/contact.php on line 16
I guess I should add this home/domain/public.html/froms/contact.php on line 16 but I don't know how to do that properly apparently.

Answer 1

Or you can write own sender. Something like this.
contact.php
$to = 'yourmail#yourdomain.ltd';
$name = filter_input(INPUT_POST, 'name', FILTER_SANITIZE_SPECIAL_CHARS);
$from = filter_input(INPUT_POST, 'email', FILTER_SANITIZE_EMAIL);
$subject = filter_input(INPUT_POST, 'subject', FILTER_SANITIZE_SPECIAL_CHARS);
$message = filter_input(INPUT_POST, 'message', FILTER_SANITIZE_SPECIAL_CHARS);
if (filter_var($from, FILTER_VALIDATE_EMAIL)) {
$headers = ['From' => ($name?"<$name> ":'').$from,
'X-Mailer' => 'PHP/' . phpversion()
];
mail($to, $subject, $message."\r\n\r\nfrom: ".$_SERVER['REMOTE_ADDR'], $headers);
die('OK');
} else {
die('Invalid address');
}

Answer 2

the code is searching for a file "php-email-form.php" in this particular directory/folder,-> ../assets/vendor/php-email-form/php-email-form.php,
check if the required php is present there, otherwise you need to create one and place it there.

Answer 3

You can't assign a variable in file_exists(). Use
if( file_exists('../assets/vendor/php-email-form/php-email-form.php')) {
include('../assets/vendor/php-email-form/php-email-form.php');
} else {
die( 'Coming Soon!');
}
or
$php_email_form = '../assets/vendor/php-email-form/php-email-form.php';
if(file_exists($php_email_form)) {
include($php_email_form);
} else {
die('Coming Soon!');
}

Answer 4

you are using the free template and the PHP Form
requires the "PHP Email Form" library and
the "PHP Email Form" library is available only in the pro version of the template.
you must to buy the pro version template
if you don't want to buy you must create your own php code
