How to Create a jQuery Ajax Contact Form in PHP

This is a simple contact form made in PHP with JQuery Ajax. Using Ajax we can avoid using a submit where you don’t want to refresh the page.

Using jQuery Ajax we can avoid using a submit where you don’t want to refresh the whole page.

In this tutorial we will use:

  1. HTML – for designing our form structure. We will use just text fields with one submit button.
  2. CSS – design our structure styles. Simple CSS, but #error and #loading classes are important
  3. JQuery – to check our contact form validation before sending to PHP, like if all fields are filled. We can do this in our PHP code too but, if we have a chance to do client-side validation, we should prefer that in case we don’t want to make SERVER-REQUEST.
  4. PHP code – sending mail.

Let’s Start!

First, create an HTML document and add the following code:

<div id="contactform">
  <form action="index.php" method="post">
    <label for="name">Name:</label>
    <input type="text" name="name" id="name" />

    <label for="email">Email:</label>
    <input type="text" name="email" id="email" />

    <label for="comment">Comment:</label>
    <textarea name="comment" id="comment"></textarea>

    <input type="submit" value="Send" name="submit" id="submit" />
    <img src="loading.gif" id="loading" alt="Wait" />
  </form>
</div>

Then our PHP code.

//if we got POST method from our JavaScript Code
<?php
if ($_POST) {
    
    // if all informations are filled
    if (($_POST[name]) & ($_POST[email]) & ($_POST[comment])) {
        
        // Your email address
        $to = "[email protected]";
        
        // Get name value
        $name = $_POST['name'];
        
        // Get email value
        $email = $_POST['email'];
        
        // Get comment text
        $comment = $_POST['comment'];
        
        // Email tile
        // if client name is Robert, title will be "Robert send you an email"
        $title = "$name send you an email"; 
        
        // Email parameters
        $mailText .= "From: $namen";
        $mailText .= "E-mail: $emailn";
        $mailText .= "Comment:n";
        $mailText .= $comment;
        
        // Set "From Header parameter"
        $headers = 'From:' . $email;
        
        // Send email
        $sendMail = mail($to, $title, $mailText, $headers);
        
        // If email is sucessful send
        if ($sendMail) {
            
            // Write sucessful message
            echo "<strong>$name</strong>, we recived your comment.";
            exit;
            
            // If email is NOT sucessful send
        } else {
            
            // Write  message
            echo "<strong>Error</strong>, please try again.";
            exit;
        }
        
        // If we dont have POST method
    } else {
        
        // Write message
        echo "<strong>Error</strong>, please try again.";
        exit;
    }
}
?>

Then we create our JavaScript code.

$(function () {
  // If "Send" button is pressed
  $("#submit").click(function () {
    // Get  value
    var name = $("#").val();

    // Get email
    var email = $("#email").val();

    // Get comment text
    var comment = $("#comment").val();

    $("#answer").remove();
    $("#error").remove();

    if (name == "" || email == "" || comment == "") {
      $("#contactform").append("<strong>Error:</strong> Fill all values.");
      $("#error").hide().fadeIn();
      return false;
    }

    $("#loading").show();

    $.ajax({
      type: "POST",
      url: "index.php",
      data: "name=" + name + "&l=" + email + "&comment=" + comment,
      error: function () {
        $("#contactform").append(
          "<strong>Error</strong> Correct This."
        );
        $("#error").hide().fadeIn();
        $("#loading").fadeOut();
      },

      success: function (rezultat) {
        $("#contactform").append(rezultat);
        $("#answer").hide().fadeIn();
        $("#loading").fadeOut();
      },
    });
    return false;
  });
});

Finally our CSS styles (#loading and #error classes are very important)

* {
     margin: 0;
     padding: 0 
}
 body {
     font: 100% Verdana, Arial, Helvetica, sans-serif;
     background: #EEE 
}
 #contactform {
     background: #FFF;
     margin: 50px auto;
     width: 300px;
     border: 1px solid #DDD;
     padding: 30px 
}
 input {
     margin-bottom: 10px 
}
 label, textarea {
     display: block 
}
 label, input, textarea, p {
     font: 0.75em Verdana, Arial, Helvetica, sans-serif;
     color: #333 
}
 input, textarea {
     padding: 5px 2px;
     border: 1px solid #CCC;
     width: 294px 
}
 textarea {
     height: 100px;
     line-height: 1.6em 
}
 input:focus, textarea:focus {
     border: 1px solid #AAA 
}
 label {
     margin-bottom: 2px;
     color: #069;
     font-size: 0.875em 
}
 #submit {
     width: 100px;
     margin-top: 10px 
}
 #submit:hover {
     border: 1px solid #AAA 
}
 #loading {
     display: none 
}
 #error {
     font-size: 0.6875em;
     background: #FFEBE8;
     border: 1px solid #C33;
     color: #333;
     display: block;
     padding: 5px 
}
 #answer {
     font-size: 0.6875em;
     background: #FFFFE0;
     border: 1px solid #E6DB55;
     color: #333;
     display: block;
     padding: 5px 
}
