Title: wppa_get_thumbs – undefined function Last modified: August 8, 2022 --- # wppa_get_thumbs – undefined function * Resolved [pfm](https://wordpress.org/support/users/pfm/) * (@pfm) * [3 years, 9 months ago](https://wordpress.org/support/topic/wppa_get_thumbs-undefined-function/) * Hi, * I did use some special code you provided me years ago. The idea is to list all picture thumbnails that fit to the TAG on the tag page. * Today I recognized this no longer works (maybe due to updates): * ``` Fatal error: Uncaught Error: Call to undefined function wppa_get_thumbs() in ... I commented the line with the call of wppa_get_thumbs. This solves the issue but sure does not show any pictures. Is there a new function or another solution I can use? Thank you! The original code was: Galerie-Fotos - passend zu dem Artikel-Schlagwort'; echo '
'; //echo do_shortcode( '[wppa type="slide" album="#tags,'.$my_tag.' size="auto" align="center"][/wppa]' ); echo wppa_insert_shortcode_output( do_shortcode( '[wppa type="thumbs" album="#tags,'.$my_tag.'" size="auto" align="center"][/wppa]' ) ); } // If no photos, say it and clean up ! else { //echo 'Es gibt leider keine passenden Fotos mit dem Schlagwort '.$my_tag.''; wppa_reset_occurrance(); } echo '
'; } ?> ``` * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwppa_get_thumbs-undefined-function%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Jacob N.

I replaced the function and now there is no error – but it does not show me the pictures… the calculation seems to return 0 * ``` wppa_get_thumbs(); $photo_count = is_array( $thumbs ) ? count( $thumbs ) : 0; // If photos, show them if ( $photo_count ) { ``` * e.g. [https://fosm.de/tag/talisker/](https://fosm.de/tag/talisker/) * Thread Starter [pfm](https://wordpress.org/support/users/pfm/) * (@pfm) * [3 years, 9 months ago](https://wordpress.org/support/topic/wppa_get_thumbs-undefined-function/#post-15902243) * I replaced wppa_get_thumbs() with wppa_get_photos() * Plugin Author [Jacob N.

The counter is still 0 and I do not get any pictures displayed. * I checked: – the album has 18 pics – each pic is “published” (not private) – each pic has the tag “Talisker” (might this be a case sensitive issue? nothing changed on this side) – I removed the if clause and it returned “no pics found” in a box – I did insert the debug line `echo 'Debug:Tag='.$my_tag;` => **Debug: Tag=,Talisker,** so there seem to be added commas…. * Anything else I can do? * Thank you! * Plugin Author [Jacob N.

tag, but then you can see if the shortcode works. * If so, find the number of photos by this code: * ``` global $wpdb; $photo_count = $wpdb->get_var( "SELECT COUNT(*) FROM $wpdb->wppa_photos WHERE tags LIKE '%$my_tag%'" ); ``` * The comma’s are assumend to be in $my_tag. Tags are stored this way: ‘,Tag1, Tag2,Tag3,’ * This is to prevent finding ‘Tag1extra’ when searching for ‘Tag1’ - This reply was modified 3 years, 9 months ago by [Jacob N.

The counter returns me the correct/expected 19. It goes inside the loop to show the pics, but the WPPA shortcode seems not to work as it returns still the above message in the box saying (translated): no pictures found that fits search criteria. * `echo do_shortcode( '[wppa type="slide" album="#tags,'.$my_tag.' size="auto" align="center"]' );` * the $my_tag: * ``` $my_tag = single_tag_title( '', false ); $my_tag = str_replace( '&', '&', $my_tag ); $my_tag = wppa_sanitize_tags( $my_tag ); $wppa['is_tag'] = $my_tag; ``` * Any other mistake in the above you can see? * Thank you! * Plugin Author [Jacob N.
