File_Exists

[Philwn]

I am trying to do a loop which uses file_exists to check if an image exists and if so display it using the following code:

 

<?php
$i = 1;
while ($i <=  {
	$filename = $img_loc . "/hovers-800px/" . $image . "-" . $i . ".jpg";
	if (file_exists($filename)) {
?>
<a class="fuglybox" rel="gxr" href="<?php echo $filename; ?>"> <!--Main thumbnail image-->
      <img src="<?php echo $img_loc; ?>/product-detail-90px/<?php $image . "-" . $i . ".jpg"; ?>" alt="" width="90" height="90" /></a>
<?php
	}
$i++;
}
?>

 

I have echoed out $filename to check my directory structure and filename is fine and copied the echoed directory out. The structure is however Http://www.xxxxxx.com/img/filename.jpg. Could this be whats causing the problem?

I spotted an error, I had missed an echo out of the thumbnail image to be displayed, I have removed the file_exists check and the code works fine, but with file_exists it doesnt

Have you echoed $filename to make sure it's a valid filesystem path?

[Philwn]

yes i haved echoed $filename and even copied the echoed filename and pasted in the address bar to check the path was correct

[Pikachu2000]

Can you post the value it echoes? I suspect you're getting a path relative to the web root, not the filesystem root.

http://www.mydomain.com/img/hovers-800px/image-1.jpg

 

It is correct but this is why i asked if there was a problem using the absolute path with file_exists

[Philwn]

Ok i have tried without using the full directory path using the ../../ relative to the directory.

 

<?php
$i = 1;
while ($i <=  {
	$filename = "../../../../../img/hovers-800px/" . $image . "-" . $i . ".jpg";
	if (file_exists($filename)) {
?>
<a class="fuglybox" rel="gxr" href="<?php echo $filename; ?>">
      <img src="../../../../../img/product-detail-90px/<?php echo $image . "-" . $i . ".jpg"; ?>" alt="" width="90" height="90" /></a>
<?php
	}
$i++;
}
?>

 

this still doesnt work yet if i remove the If (file_exists) it works fine although it will always display 8 images even if there are 5.

 

<?php
$i = 1;
while ($i <=  {
	$filename = "../../../../../img/hovers-800px/" . $image . "-" . $i . ".jpg";
?>
<a class="fuglybox" rel="gxr" href="<?php echo $filename; ?>">
      <img src="../../../../../img/product-detail-90px/<?php echo $image . "-" . $i . ".jpg"; ?>" alt="" width="90" height="90" /></a>
<?php
$i++;
}
?>
