I am using a jQuery AJAX request to a page called like.php that connects to my database and inserts a row. This is the like.php code:
<?php
// Some config stuff
define(DB_HOST, 'localhost');
define(DB_USER, 'root');
define(DB_PASS, '');
define(DB_NAME, 'quicklike');
$link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die('ERROR: ' . mysql_error());
$sel = mysql_select_db(DB_NAME, $link) or die('ERROR: ' . mysql_error());
$likeMsg = mysql_real_escape_string(trim($_POST['likeMsg']));
$timeStamp = time();
if(empty($likeMsg))
die('ERROR: Message is empty');
$sql = "INSERT INTO `likes` (like_message, timestamp)
VALUES ('$likeMsg', $timeStamp)";
$result = mysql_query($sql, $link) or die('ERROR: ' . mysql_error());
echo mysql_insert_id();
mysql_close($link);
?>
The problematic line is $likeMsg = mysql_real_escape_string(trim($_POST['likeMsg']));. It seems to just return an empty string, and in my database under the like_message column all I see is blank entries. If I remove mysql_real_escape_string() though, it works fine.
Here's my jQuery code if it helps.
$('#like').bind('keydown', function(e) {
if(e.keyCode == 13) {
var likeMessage = $('#changer p').html();
if(likeMessage) {
$.ajax({
cache: false,
url: 'like.php',
type: 'POST',
data: { likeMsg: likeMessage },
success: function(data) {
$('#like').unbind();
writeLikeButton(data);
}
});
} else {
$('#button_container').html('');
}
}
});
All this jQuery code works fine, I've tested it myself independently.
Any help is greatly appreciated, thanks.
