I am new to PHP and really just troubleshooting a migration issue (moving from live working server to new server with this error). I'm not well versed in coding so I apologize in advance if I'm overlooking something stupid simple.

Here's the error:

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /###/###/public_html/diss/modules/CMS/CMS_Class.php on line 134

Here's the code from line 134:

while ($block = mysql_fetch_assoc($blockresult)){
	 		$blockid = $block['blockid'];
	 		$blockorder = $block['blockorder'];
	 		$typeid = $block['typeid'];
			$title = $block['title'];

And lastly here is the entire code:

<?php

	private $id;	// page id
	private $editable = FALSE;
	public $title;
	public $parentid;
	public $pagetype;

		$CMS = ($_SERVER['PHP_SELF'] == '/page.php' || $virtual_file);
		// if CMS, make sure the page even exists before continuing further
		if ($CMS) {
			if ($virtual_file)
				$this->virtual_file = $virtual_file;
			else {
				$temp = explode('.', $_GET['id']);
				$this->virtual_file = mysql_escape_string($temp[0]);
			}

I can't see any connect information
you will need to connect to your daatbase at the top of the script,
then select the database when making the query

//Connect to database
$host="localhost"; // Host name 
$username=""; // Mysql username 
$password=""; // Mysql password 
$db_name=""; // Database name 
$tbl_name="members"; // Table name 
mysql_pconnect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

Since you're new we'll cut you some slack! But if you noticed there is a pinned thread at the top of the forum that talks specifically about this error. Be sure to check out this great thread. It's bound to have your solution!

I've added the DB connection settings to the top of the script and it didn't help at all... I also read the FAQ (prior and post your response) - I'm clueless.

I am new to this, but I'm not really a programmer. I'm just troubleshooting this for a client and I would really like some help on this error. If you don't mind taking the time to explain how to troubleshoot, it would mean a lot.

I added the connection string, database select statement and the mysql_query() call with no success...

Again, thanks in advance for your patience and input :)

The mysql_fetch_assoc() error can also be due to an invalid mysql_query() syntax input. So try doing mysql_query($sql) or die(mysql_error()); so that you get debugging information. Then tell us what additional errors it reports back.
Also don't forget to use mysql_real_escape_string().

Thanks cwarn23!

The message displayed now reads "Query was empty"...
