loginSend.js
- $('#loginButton').on('click', function(){ //the id of the submit button = #loginButton
- var username = $('#userfield').val();
- var password = $('#passfield').val();
- if (username.length == 0 || password.length == 0 || password.length < 6) { // checks if username and pass have been entered
- $('#fillFields').text('*Please enter a valid username/password'); //#fillfields = the div where error message should appear in JQuery UI dialog box
- } else {
- //$('#formLogin').text('You have successfully logged in').dialog('close'); //Closes dialog box if logged in currently not in use
- $.post('loginProcess.php', {username: username, password: password}, funtion(data){ // sends data to loginProcess.php
- if (data == true){ //checks if the loginProcess has returned true (if the username exists or not)
- alert('true'); // just to check if the code works, display an alert message
- }
- }
- });
- });
loginProcess.php
- <?php
- require 'config.php';
- // LOGIN FORM Process
- if (user_exists('super')){ //user_exists() = a user defined function in config.php
- return true;
- }
- ?>
config.php
- function sanitize($data){
- return mysql_real_escape_string(strip_tags($data));
- }
- function user_exists($username){
- $username = sanitize($username);
- $query = mysql_query("SELECT COUNT(`id`) FROM `users` WHERE `Username` = '$username'");
- return (mysql_result($query, 0) == 1) ? true : false;
- }
i don't understand what i've done wrong. I'm trying to create a JQuery UI dialog, login form. Normlly when the user types in a username i want it to check if the username exists. But nothing happens. Since i added JQuery Post it doesn't work. How do i get it to display if username exists or not. I think the problem is in $.post because before i added that, my code works, but after i added it it stopped working. It doesn't even display error messages? The whole code just doesn't work.
How do i fix this and get it to work as intended?
Thanks
