Why is the feedback form not working correctly?

Question

PHP

Hello to all readers!)

In general, there is a form, not written by me, taken for use))
Here is php

<?php 
  $errors = '';
  $limit_size=10000000;
  $myemail = 'МЫЛО'; 
  if(empty($_POST['name'])  ||
     empty($_POST['email']) ||
     empty($_POST['subject']) ||
     empty($_POST['message']))
  {
  $errors .= "\n Error: Required Field";
  }	

    /*data*/
  $name = $_POST['name'];
  $email = $_POST['email'];
  $subject = $_POST['subject'];
  $message = $_POST['message'];
  $headers = "From: $email";

  if (!eregi(
  "^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$", 
  $email))
  {
  $errors .= "\n Error: Invalid Email Address";
  }

  if( empty($errors))
  {
  $to = $myemail;
  $email_subject = "A New Message Awaits: $subject";
  $txt = "You have received a new message from your website. Details are given below.\n Name: $name \n Email: $email \n Subject: $subject \n Message: \n $message";
  
  // preparing attachments
  $files = array();
    if($file_one)
     {
     array_push($files,$file_one);
   }	  
   
    $semi_rand = md5(time()); 
    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x"; 
    $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\""; 
    $message = "This is a multi-part message in MIME format.\n\n" . "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n" . "Content-Transfer-Encoding: 7bit\n\n" . $txt . "\n\n"; 
    $message .= "--{$mime_boundary}\n";
    
      for($x=0;$x<count($files);$x++){
      $file = fopen('tmp/'.$files[$x],"rb");
      $data = fread($file,filesize('tmp/'.$files[$x]));
      fclose($file);
      $data = chunk_split(base64_encode($data));
      $message .= "Content-Type: {\"application/octet-stream\"};\n" . " name=\"$files[$x]\"\n" . 
      "Content-Disposition: attachment;\n" . " filename=\"$files[$x]\"\n" . 
      "Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
      $message .= "--{$mime_boundary}\n";
    }
 
  mail($to, $email_subject, $message, $headers);
  }
?>

Here is the html

<section id="contact" class="contact_area">
      <div class="container-fluid">
        <div class="row">		
          <div class="col-lg-6 col-sm-12 col-xs-12 no-padding" data-aos="fade-up">
            <div class="contact_address">
              <h3>Контакты</h3>				
              <ul>
                <li><i class="fa fa-envelope"></i>мыло@gmail.com</li>
                <li><i class="fa fa-calendar"></i>Понедельник - Пятница</li>
                <li><i class="fa fa-clock-o"></i>9:00 - 17:00</li>
              </ul>
            </div>
          </div><!-- END COL -->						
          <div class="col-lg-6 col-sm-12 col-xs-12 no-padding" data-aos="fade-up">
            <div class="contact">
              <form id="contact-form" method="post" enctype="multipart/form-data">

                  <div class="form-group col-md-6">
                    <input type="text" name="name" class="form-control" id="first-name" placeholder="Имя" required="required">
                  </div>
                  <div class="form-group col-md-6">
                    <input type="email" name="email" class="form-control" id="first-email" placeholder="Email" required="required">
                  </div>
                  <div class="form-group col-md-12">
                    <input type="text" name="subject" class="form-control" id="subject" placeholder="Тема" required="required">

                    <textarea rows="6" name="message" class="form-control" id="description" placeholder="Сообщение" required="required"></textarea>
                  </div>
                  <div class="col-md-12">
                    <div class="actions">
                      <input type="submit" value="Отправить" name="submit" id="submitButton" class="btn btn-lg btn-contact-bg" title="Подтвердите Ваше сообщение!" />
                    </div>
                  </div>
                </div>
              </form>
            </div>
          </div>
        </div>			
      </div>	
    </section>

The bottom line is that the "Submit" button changes color on hover, but is not clickable, as I understand it. Nothing happens when you click. It is

necessary that the data entered be actually sent ..)
Be so kind as to tell me where and what I'm doing wrong?

Answer 1

How does html know about php? The action="" attribute of the form tag is missing.

Answer 2

Hmm .. do you indicate email as “soap”?

Answer 3

Here is the JS

$(document).ready(function() {
  $('form#contact-form').submit(function() {
  $('form#contact-form .error').remove();
  var hasError = false;
  $('.requiredField').each(function() {
  if(jQuery.trim($(this).val()) == '') {
    var labelText = $(this).prev('label').text();
    $(this).parent().append('<span class="error">Вы забыли ввести '+labelText+'</span>');
    $(this).addClass('inputError');
    hasError = true;
    } else if($(this).hasClass('email')) {
    var emailReg = /^([\w-\.][email protected]([\w-]+\.)+[\w-]{2,4})?$/;
    if(!emailReg.test(jQuery.trim($(this).val()))) {
    var labelText = $(this).prev('label').text();
    $(this).parent().append('<span class="error">Вы ввели не верный '+labelText+'</span>');
    $(this).addClass('inputError');
    hasError = true;
    }
    }
    });
    if(!hasError) {
    $('form#contact-form input.submit').fadeOut('normal', function() {
    $(this).parent().append('');
    });

     $("#loader").show();
        $.ajax({
            url: "contact.php",
            type: "POST",
            data:  new FormData(this),
            contentType: false,
            cache: false,
            processData:false,
            success: function(data){
        $('form#contact-form').slideUp("fast", function() {
        $(this).before('<div class="success">Спасибо! Ваше письмо было отправлено.</div>');
        $("#loader").hide();
        })
            }           
       });
     
     return false;
    }
 
   });
});
