I get: Warning: Invalid argument supplied for foreach()

Hello there,

I am getting the same error.

I can select the gallery from within the page I want to display it on.

I used the following code to pull the gallery in:

<?php
foreach ( get_field ( ‘nextgen_gallery_id’ ) as $nextgen_gallery_id ) :
if ( $nextgen_gallery_id[‘ngg_form’] == ‘album’ ) {
echo nggShowAlbum( $nextgen_gallery_id[‘ngg_id’] ); //NextGEN Gallery album
} elseif ( $nextgen_gallery_id[‘ngg_form’] == ‘gallery’ ) {
echo nggShowGallery( $nextgen_gallery_id[‘ngg_id’] ); //NextGEN Gallery gallery
}
endforeach;
?>

In the first line –

foreach ( get_field ( 'nextgen_gallery_id' ) as $nextgen_gallery_id ) :

You need to change ‘nextgen_gallery_id’ with the id of your gallery.

HAHAHAAHAHA…?@ckfrantz No!

You need to wrap the foreach in an if statement to insure $nextgen_gallery_id ≠ null.

@ckfrantz – that worked for me.
