Bonjour,

dans la page “gallery settings” je peux choisir une “preview image”, c’est-à-dire l’image qui ‘representera’ ma galerie. Le problème c’est que je ne sais pas l’afficher sur mon site. J’aimerais m’en servir comme “preview” dans la page category.php.

Quelqu’un saurait-il m’aider ?

Merci 🙂

Gueblo.

I’m using the following in my portfolio:

<?php
function getItemPreview()
{
	global $wpdb, $post;
	$img_cat = $wpdb->get_row('SELECT * FROM '.$wpdb->nggallery.' WHERE gid = '. get_post_meta($post->ID, 'pf_nextgen_gallery', true) .' ORDER by gid DESC limit 0,1');
	$first_image = $wpdb->get_row('SELECT * FROM '. $wpdb->nggpictures .' WHERE exclude != 1 AND galleryid = '. get_post_meta($post->ID, 'pf_nextgen_gallery', true) .' ORDER by pid DESC limit 0,1');

 	$albumPreview = $wpdb->get_results('SELECT pid, filename FROM '.$wpdb->nggpictures.' WHERE pid = '.$img_cat->previewpic.'', OBJECT_K);

	$toppreview = get_option ('siteurl') . '/' . $img_cat->path . '/' . $first_image->filename;

	if ( $previewimg = $albumPreview[$img_cat->previewpic]->filename )
	{
		$toppreview = get_option ('siteurl').'/' . $img_cat->path . '/' . $previewimg;
		echo '<style type="text/css">#image { background-image:url('.$toppreview.')!important; }</style>';
	}
	else
	{
		echo '<style type="text/css">#image { background-image:url('.$toppreview.')!important; }</style>';
	}
}
?>

As you can see I add a custom field pf_nextgen_gallery that stores the ID of the gallery I want the preview of on that page/post. Ofcourse the output can be changed according to your wishes 🙂
