Topic: TIP: Count number of images in gallery with php

[Syrinx]

This will count how many .jpg and .gif images there are in a listing's gallery, you can use this in the vcard or detail view templates:

<?php $gallery_images = count(glob("images/com_sobi2/gallery/$mySobi->id/$mySobi->id{_image*.gif,_image*.jpg}", GLOB_BRACE)); ?>

You can then show the # of images by using:

<?php echo $gallery_images; ?>

You can also test/use the variable $gallery_images in other php operations ("if" statement to show gallery tab etc).

I cant get this working on my vCard template.

Any ideas why this might be? It works fine on my details view template.

On the page above if you scroll to the bottom and go to Gold Listing example, this listing has images so should show 5 in the image count.

Make sure this line near the top of the template isn't commented out:
$mySobi = new sobi2( $id );

If it looks like this:

// $mySobi = new sobi2( $id );

Remove the two slashes

Hello Syrinx,

I have self-made gallery and I'm pulling images from folders manually.

First, I get the number of images (using your code) than iI use FOR loop to echo all images.
I'm using variable from FOR loop to tuck correct image number.

Here is the code:

Code: [Select]

<?php $gallery_images = count(glob("images/com_sobi2/gallery/$mySobi->id/$mySobi->id{_image*.png,_image*.jpg}", GLOB_BRACE)); ?>
<?php if ($gallery_images == 0) {
echo "<strong>Napomena: </strong>Galerija nije dodana ili ne sadrži slike.";
} ?>
<?php
$images_limit = $gallery_images;
for ( $counter = 1; $counter <= $images_limit; $counter += 1) { ?>
<a href='<?php echo JURI::base(); ?>images/com_sobi2/gallery/<?php echo $mySobi->id; ?>/<?php echo $mySobi->id; ?>_image_<?php echo $counter ?>.jpg' title='Konzum 3' onclick="return hs.expand(this)"><img src='<?php echo JURI::base(); ?>images/com_sobi2/gallery/<?php echo $mySobi->id; ?>/<?php echo $mySobi->id; ?>_thumb_<?php echo $counter; ?>.jpg' alt='Konzum 3' class="thumb" title='Konzum 3' /></a>
<?php } ?>

This code is working but ONLY for jpg images.

Code: [Select]

_image_<?php echo $counter ?>.jpg

I would love to have code which will detect image extension (.png  or  .jpg). and than create this:

_image_<?php echo $counter ?>.png

or this

_image_<?php echo $counter ?>.jpg


Can You tell me how can I do this?
