ajax jquery form stopped sending emails

hawk :

I have a form which was sending emails from the server before but all of a sudden it stopped working. I cant seem to figure out the issue. When I use the form without ajax then email works perfectly. I saw http 200 code in the dev tools and no errors. Any help would be much appreciated. Thank you.

html:


<form id="form1" class="form-action" action="" method="POST">

        <input type="text" name="name" id="name" class = "name" required />
        <input type="email" name="email" id="email"  required />
        <input type="text" name='company' id="company" class="company" required />
        <textarea class= "message" name="message" id="message" required /> 
        </textarea>

    $(document).ready(function(){

Mr Khan :

You seem to be missing the Recaptcha secrets. Removing the Recaptcha if condition it works fine.

<?php

    $email_to = '[email protected]'; //-----------> Invalid Email Id was added here
    $email_subject = 'form submission';
    $email = $_POST ['email'];

    $required = array('name','email','company', 'message');


    $form1_complete = FALSE;

    $validation = array();

    if(!empty($_POST)) {

        foreach($_POST as $key => $value) $_POST[$key] = remove_email_injection(trim($value));

        foreach($required as $field) {

            if(!array_key_exists($field, $_POST)) array_push($validation, $field);

            if($_POST[$field] == '') array_push($validation, $field);

            if($field == 'email') if(!validate_email_address($_POST[$field])) array_push($validation, $field);
        }

        if(count($validation) == 0) {
            $email_content = 'New Comment: ' . "\n\n";

            foreach($_POST as $key => $value) {
                if($key != 'submit') $email_content .= $key . ': ' . $value . "\n\n ";
            }

            //Recaptca Secrets are Missing?????? Random string passed!
            $recaptcha_secret = "x";

            $response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret="
            .$recaptcha_secret."&response=".$_POST['g-recaptcha-response']); //-----> Also Recapta response from
            //the form is also missing since there its not working and neither getting passed

            $response = json_decode($response, true);

            //Printed the Output in which it shows the recapta Error
            echo "<pre>";
            print_r($response);

            //If you ae to remove the Recapta Condition, the mail will be send!
            // if($response["success"] === true) {
                echo "==========";

                echo "email_subject:".$email_subject.", email:".$email.",email_to:".$email_to;
                mail($email_to, $email_subject, $email_content, "From:" . $email);

                echo "==========";

            // }
            // else
            // {
            //     echo "Failed";
            // }

            echo "<br>";
            echo 'submitted';
        }
    }

    function validate_email_address($email = FALSE) {
        return (preg_match('/^[^@\s]+@([-a-z0-9]+\.)+[a-z]{2,}$/i', $email))? TRUE : FALSE;
    }

    function remove_email_injection($field = FALSE) {
        return (str_ireplace(array("\r", "\n", "%0a", "%0d", "Content-Type:", "bcc:","to:","cc:"), '', $field));
    }

?>

Hope it helps :)
