slice / filter problem

[Alessio Dal Bianco]

Hi all,

i found a problem regarding filtering items.

For example i limit the number of images (4) in this way:

<?php if( count($page->images) )  foreach( $page->images->filter("limit=4") as $seoImg ): ?>
        <meta property="og:image" content="<?php echo "http://".$config->httpHost.$seoImg->size(300,300)->url ?>" />
<?php endforeach; ?>

More later in the template i create the main gallery with ALL images (about 10 images):

<?php foreach( $page->images as $img ): ?>
                <li>
                    <div class="text" style="background-image:url(<?php echo $img->width(80)->url ?>)">
                        <?php echo $img->description; ?>
                    </div>
                </li>
<?php endforeach; ?>

But when i call "$page->images" it returns me only 4 items, same behavior with "slice(0,4)". I've tried also with "$page->get('images')" with the hope that in this way i can override the filter... But nothing, it seems that the results of filters override the original results in the property.

Alessio, that's the intended behavior of filter. It changes your wireArray forever

Use find() instead on your first foreach.

$page->images->find("limit=4")

  my fault.

Also slice works as expected, because when i was trying there was another same filter below for other meta tags!

Thank you diogo!
