I have a slightly older version of NGG because I have modded it and have yet to transfer those mods to the latest version. But I just made another minor change that I wanted to document before I forget what I did.<\/p>\n
Using the [nggtags gallery=tag_selection]\u00a0 works well for showing the images from the gallery that are tagged as an automated gallery creation.<\/p>\n
But I wanted to get the captions displayed as well like the syntax for the standard gallery by id display [nggallery id=60 template=caption].\u00a0 So I needed to add the ” template=caption” as an option for the nggtags shortcode.<\/p>\n
Edit \/wp-content\/plugins\/nextgen-gallery\/nggfunctions.php<\/p>\n
Around line 867 should start the function into which I inserted the $template value (with relevant comma’s etc.) at 3 places as highlighted with the new text.<\/p>\n
[php highlight=”1,13,23″]
\nfunction nggShowGalleryTags($taglist, $template = ”) {<\/p>\n
\/\/ $_GET from wp_query
\n$pid\u00a0\u00a0\u00a0 = get_query_var(‘pid’);
\n$pageid = get_query_var(‘pageid’);<\/p>\n
\/\/ get now the related images
\n$picturelist = nggTags::find_images_for_tags($taglist , ‘ASC’);<\/p>\n
\/\/ look for ImageBrowser if we have a $_GET(‘pid’)
\nif ( $pageid == get_the_ID() || !is_home() )
\nif (!empty( $pid ))\u00a0 {
\n$out = nggCreateImageBrowser( $picturelist, $template);
\nreturn $out;
\n}<\/p>\n
\/\/ go on if not empty
\nif ( empty($picturelist) )
\nreturn;<\/p>\n
\/\/ show gallery
\nif ( is_array($picturelist) )
\n$out = nggCreateGallery($picturelist, false, $template);<\/p>\n
$out = apply_filters(‘ngg_show_gallery_tags_content’, $out, $taglist);
\nreturn $out;
\n}<\/p>\n
[\/php]<\/p>\n
That sorts out the function that is called from the\u00a0 \/wp-content\/plugins\/nextgen-gallery\/lib\/shortcodes.php<\/p>\n
Around line 114 there is a string evaluation test process that we change to look for a second option referenced as template= etc..\u00a0 shown in the highlighted line.<\/p>\n
[php highlight=”6″]<\/p>\n
if ( stristr( $content, ‘[tags’ )) {
\n$search = "@(?:<p>)*s*[tagss*=s*(.*?)s*]s*(?:<\/p>)*@i";
\nif (preg_match_all($search, $content, $matches, PREG_SET_ORDER)) {<\/p>\n
foreach ($matches as $match) {
\n$replace = "[nggtags gallery="{$match[1]}" template="{$match[2]}"]";
\n$content = str_replace ($match[0], $replace, $content);
\n}
\n}
\n}<\/p>\n
[\/php]<\/p>\n
Finally around line 273 there is the call to the nggShowGalleryTags in the show_tags function. Insert a new line for $template as a parameter and to the output option.<\/p>\n
[php highlight=”5,12″]<\/p>\n
function show_tags( $atts ) {<\/p>\n
extract(shortcode_atts(array(
\n‘gallery’\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 => ”,
\n‘template’\u00a0 => ”,
\n‘album’\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 => ”
\n), $atts ));<\/p>\n
if ( !empty($album) )
\n$out = nggShowAlbumTags($album);
\nelse
\n$out = nggShowGalleryTags($gallery, $template);<\/p>\n
return $out;
\n}<\/p>\n
[\/php]<\/p>\n
Now the nggtags option that will create a custom gallery from Tagged images can optionally include the image caption as well.<\/p>\n
