For some reason, JavaScript/PHP wont delete my data from MySQL! Here is the rundown of the problem.
I have an array that displays all my MySQL entries in a nice format, with a button to delete the
entry for each one individually. It looks like this:
<?php
include("login.php");
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("<br/><h1>Unable to connect to MySQL, please contact support at
[email protected]</h1>");
//select a database to work with
$selected = mysql_select_db($dbname, $dbhandle)
or die("Could not select database.");
//execute the SQL query and return records
if (!$result = mysql_query("SELECT `id`, `url` FROM `videos`"))
echo 'mysql error: '.mysql_error();
//fetch tha data from the database
while ($row = mysql_fetch_array($result)) {
?>
<div class="video"><a class="<?php echo $row{'id'}; ?>" href="http://www.youtube.com/watch?v=<?php echo $row{'url'}; ?>">http://www.youtube.com/watch?v=<?php echo $row{'url'}; ?></a><a class="del" href="javascript:confirmation(<? echo $row['id']; ?>)">delete</a></div>
<?php }
//close the connection
mysql_close($dbhandle);
?>
The delete button has an href of javascript:confirmation(<? echo $row['id']; ?>) , so once you click on delete, it runs this:
<script type="text/javascript">
<!--
function confirmation(ID) {
var answer = confirm("Are you sure you want to delete this video?")
if (answer){
alert("
Entry Deleted")
window.location = "delete.php?id="+ID;
}
else{
alert("No action taken")
}
}
//-->
</script>
The JavaScript should theoretically pass the 'ID' onto the page delete.php. That page looks like this (and I think this is where the problem is):
<?php
include ("login.php");
mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
mysql_select_db ($dbname)
or die("Unable to connect to database");
mysql_query("DELETE FROM `videos` WHERE `videos`.`id` ='.$id.'");
echo ("Video has been deleted.");
?>
If there's anyone out there that may know the answer to this, I would greatly appreciate it. I am also opened to suggestions (for those who aren't sure).
Thanks!
