Semi-working AJAX code: what's wrong?

Hi everyone,

 

First time here, so I am hoping one of y'all will be able to help me with my problem.

 

Quick background: I have a basic HTML form. I'd like to store all of the data from that form in a MySQL database. I was able to do this with PHP, but I don't want the page to refresh, so naturally I turned to AJAX. I have ZERO exposure to AJAX, and am learning on-the-go, so apologies if I am making an elementary mistake.

 

Anyway, here's the code of the HTML page with the input form and the AJAX code at the very end.

 

My main problem: upon clicking the "apply" button, I receive the "failure" dialog box, even though the data DOES get stored inside my database.

 

<form>
<table cellpadding="10">

<tr>
<td><b>Chapter:</b></td>
<td><input type="text" name="chapter"></td>
</tr>

<tr>
<td>First Name:</td>
<td><input type="text" name="first"></td>

<option value="other">Other</option>
</td>
</tr>

<tr>

<select name="year_in_school">
<option value="freshman">Freshman</option>

</form>

<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.8.0/jquery.min.js"></script>
    <script type="text/javascript">
        $(function() {
            $('form').bind('submit', function(){
                $.ajax({
                    type: 'post',
                    url: "/InsertNewMentor.php",
                    dataType: 'html',
                    data: $('form').serialize(),
                    ssuccess: function(){
    			alert('success');
  },
  error: function(){
    alert('failure');
  }
});

                return false;
            });
        });
    </script>

 

And here's InsertNewMentor.php

 

<?php
$username="";
$password="";
$database="";

$first = $_POST['first'];
$last = $_POST['last'];
$email = $_POST['email'];
$gpa = $_POST['gpa'];

$address = $_POST['address'];
$phone = $_POST['phone'];
$gender = $_POST['gender'];
$ethnicity = $_POST['ethnicity'];
$year_in_school = $_POST['year_in_school'];
$suite_number = $_POST['suite_num'];
$city = $_POST['city'];
$state = $_POST['state'];
$zip_code = $_POST['zip_code'];
$major = $_POST['major'];
$twitter_handle = $_POST['twitter_handle'];
$why_moneythink = $_POST['why_moneythink'];
$teaching_experience = $_POST['teaching_experience'];
$date = date("m/d/Y");

mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");

$query = "INSERT INTO students VALUES ('','$address','$phone','$first','$last','$gender', '$ethnicity', '$year_in_school', '$email', '$suite_number','$city','$state','$zip_code','$major','$gpa','$twitter_handle','$why_moneythink','$teaching_experience','pending','$date')";
mysql_query($query);

mysql_close();
?>

You will also need to read up on input validation and output escaping, as your script is wide open to attackers.

Also, please indent your code properly, as it makes it a lot easier to read. Preferably also use proper and semantic HTML, leaving all of the formatting to CSS. That means, no use of tables for layout purposes.

<form method="post" action="">
    <fieldset>
        <legend>Login form</legend>

        <label for="uname">Username:</label>
        <input id="uname" type="text" name="username" value="">

        <label for="passw">Password:</label>
        <input id="passw" type="password" name="password">
    </fieldset>

    <fieldset>
        <input type="submit" name="submit" value="Log in">
   </fieldset>
</form>

 

As you can see, this is a lot easier to read than the code you posted above. By using CSS you can make it look exactly the same, with the added benefit that it'll be useful everywhere.
