[SOLVED] Using isset to run some php when form is submitted.

[dprichard]

I am trying to modify the login script one of the moderators here pointed me to.  It looks like it is working for me but I need it to only run after someone submits the form.  I tried adding isset, but when I did it just post back and does perform the query.

 

Here is my php

 

<?php 
session_start();
require_once('../Connections/prbc.php');

if(isset($_POST['login'])){
$username = '';
$password = '';

if (isset ($_POST['username']) && $_POST['username'] != '')

$username = $_POST['username'];

if(isset ($_POST['password']) && $_POST['password'] != '')

$password = $_POST['password'];

$username = mysql_real_escape_string( $username );
$password = mysql_real_escape_string( $password );

$db_password = md5($password);

mysql_select_db('prbcweb') or die(mysql_error());
$login = mysql_query("SELECT * FROM prbc_user WHERE `user_name` = '$username' AND `user_pass` = '$db_password'");
$row_login = mysql_fetch_array($login);
$row_login_total = mysql_num_rows($login);

if ($row_login_total == 1) {
$_SESSION['MM_Username'] = $row_login['user_name'];
$_SESSION['UID'] = $row_login['user_id'];
header("Location: approver.php");

} elseif ($row_login_total <> 1) {
header("Location: login_2.php");
}
}
?> 

 

And here is my form.  I am not sure what I am doing wrong.  Any assistance would be greatly appreciated.

 

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST" name="login" id="login">
              <p>Username: <br>
                <input name="username" type="text" id="username">
</p>
              <p>Password:<br>
                <input name="password" type="password" id="password"> 
</p>
              <p>
                <input type="image" name="submit" src="../images/button_login.gif" width="100" height="26">
</p>
              </form>

Try changing the image button to type submit, use CSS to get the right width/height/bg-image, and change the isset test from $_POST["login"] to $_POST["whatever_name_you_call_the_submit_button"].

Okay, it works if I change the input type to submit.  Is there no way to use an image for the submit button and still do this?

Nevermind found an answer.  Read your post again and saw the part about css.
