Invalid argument supplied for foreach()

[jrahma]

Hi,

I am trying to use the following in my page but getting the above error:

<?php foreach ($result->data as $post) { ?>
	<a href="<?php echo $post->images->standard_resolution->url ?>" data-fancybox-group="gallery" title="<?php echo $post->caption->text ?>"><img src="<?php echo $post->images->thumbnail->url ?>" alt="<?php echo $post->caption->text ?>" /></a>
<?php } ?>

So [font=monospace]$result->data[/font] is not an array (or at least, not something that can be iterated).

You might want to
A) alter any function that defines $result->data to make sure that it always returns an array

or

😎 use [man]is_array[/man] to check if $result->data is actually an array before trying to use foreach on it.
