[SOLVED] Pick a pic

[Brian W]

I am trying to create a function that will find the thumbnail for a given property for a real estate website I am working on. In a folder called images/ I have the pics named first by the reference number to the property then a unique number (example: 101_2.jpg is the second picture for the property 101)

For every property, there is a thumbnail pic named ###_thumb.jpg (101_thumb.jpg)

So, what I figured I should do is pull the extension off of the name using explode (was using list and split, but moved to explode hoping that it would fix my problem... it didn't of course) then I try to find a match of the ref number I input into the function that has "_thumb" on it.

Here is what I have,

<?php
function findthumb($IDset){
$dir= 'images/';
foreach (glob($dir."*", GLOB_NOCHECK) as $filename) {
	$listingID = explode(".", $filename);
		if($listingID[0] == $IDset."_thumb") {
			$img = $filename; }
} return $img;
}

?>
<?php $id = "101"; echo findthumb($id); ?>

I'm using 101 as a test again.

I've echod every variable out and every thing seems to work up to

if($listingID[0] == $IDset."_thumb") {
$img = $filename; }

Even though $listingID[0] echos as 101_1, 101_2, 101_thumb    Its *seems* not catching as being == to $IDset

any input appreciated.

Never mind, figured out what the problem was.

I echod out $listingID[0] again and realized that it wasn't coming out as ###_thumb, it was images/###_thumb. so I just had to add $dir onto my if( == ) statement
