Running Two "foreach" loops?

[MatthewSchenker]

Greetings,
My first post here. I'm learning PHP as rapidly as I can, but I still have some basic questions.

OK, I'm trying to run the Gallerific gallery script on my site. The way Gallerific works, it looks at an unordered list to populate the gallery. In each list item, it grabs a main image and a thumbnail image.

I have folders that are created dynamically as a user uploads photos. There is a main folder and a "thumbs" sub-folder. That's all taken care of before the script comes into play

I need to loop through both the main images and the thumbnails at the same time, and call each one in the list items.

I know this code must be wrong, but I'll post it as a starting place. Can someone help me figure out how to do this correctly? Maybe I should not even be using foreach?

<div id="thumbs" class="navigation">
                    <ul class="thumbs noscript">
<?php foreach($cck->get( 'property_listing_images' )->value as $large){
    foreach($cck->getValue( 'property_listing_images' )->value as $thumb1){ ?>
    <li>
    <a class="thumb" href="images/<?php echo $large->value; ?>" title="Title X">
    <img src="images/<?php echo $thumb1->value; ?>" alt="Title X" />
    </a>
    </li>
</ul>
<?php } ?>
<?php } ?>
</div>

Thank you ahead of time for your help!

I hesitant to suggest anything without a better understanding of what you would be looping on in each of those foreach()'s (and suspecting you may only need one foreach() in the end). It might be useful to see what arrays are actually being processed, so I'm wondering if you could do something like the following and show the results here within [noparse]

[/noparse] tags? (We don't need to see the entire arrays, just the first couple or three elements of each, perhaps.)
[code=php]
<?php
// whatever you do to initialize $cck, then... 
$largeImages = $cck->get( 'property_listing_images' )->value;
$thumbImages = $cck->getValue( 'property_listing_images' )->value
echo "<pre>Large:\n";
print_r($largeImages);
echo "\nThumb:\n";
print_r($thumbImages);
echo "</pre>";
?>

NogDog,
Thank you very much for jumping in to help!

I'm using Joomla (in the process of moving to a PHP framework -- a whole other story). Those particular "cck" references are to Joomla fields.

I apologize, but I think I might have complicated my question by referring to those Joomla-specific fields.

Maybe a better approach would be to reference folders. After all, the images are all uploaded to folders for the main image and the thumbnails. Each gallery grabs files from those folders.

OK, so assuming I reference straightforward folders, how would I loop the foreach() statement?

Thanks,
Matthew

Is there some sort of file naming convention in use, where if you know the name of the main image file then you would know the name of the thumb? If so, then you could just loop on the main image directory, and then extrapolate the thumbnail name based on the image name.

$dir = $userId; // for example
$images = glob($dir.'/images/*');
foreach($images as $img) {
   printf(
      "<a href='%s/images/%s'><img src='%s/thumbs/%s' /></a>",
      $dir,
      basename($img),
      $dir,
      basename($img)
   );
}

NogDog,
Thank you so much for helping me through these newbie questions! I'm working hard to learn, and this is really helpful...

Yes, the images and thumbs have identical names. One is stored in the main folder, and the other is stored in a "thumbs" sub-directory.

I like this approach much better, as it is closer to "standard" practices and moves me away from using those Joomla-specific references.

I'll give it a try now and see if it works. If not, I may have to bug you one more time!

Thank you again. I really appreciate this help.

Thank you for your help! I have been looking into this issue and combining your knowledge with other bits, I figured it out!

I'm working hard to get better at PHP, and this kind of discussion really help.

Thanks again for your help,
