Thanks for the compliment and for your question.
The easy way to use [mla_gallery] from PHP code is by calling the WordPress do_shortcode() function. Here are two earlier topics with some examples:
do_shortcode categories and taxonomies not working
album name begins with (like)
Using do_shortcode() is the best way to insulate your code from changes in future MLA versions. If you must, you can call the MLA shortcode processing functions directly, e.g.:
echo MLAShortcodes::mla_gallery_shortcode( $attr, $content );
A direct call gives you some flexibility in composing the shortcode parameters and avoiding some WordPress parsing issues but is somewhat more difficult to implement.
I am marking this topic resolved, but please update it if you have any problems or specific questions about calling [mla_gallery] from your application’s PHP code. Thanks for your interest in the plugin.
Hi
Thanks a lot!
I tried to use MLAShortcodes::mla_gallery_shortcode but just to be sure.
My $attr array looks like :
$attr = array(
'post_mime_type' => 'all',
'tax_query' => array ('taxonomy' => 'attachment_tag', 'field' => 'id', 'terms' => array($wp_query->query_vars['photo_id']), 'include_children' => 0
),
'mla_target' => 'blank',
'columns' => 2,
'posts_per_page' => 30,
'size' => 'large',
'link' => 'file',
);
Is it correct ?
Then I call echo MLAShortcodes::mla_gallery_shortcode( $attr, $content );
But I don’t see what $content is supposed to be 🙂
For the moment, it makes my page crash and returns a blank document.
Thanks again for your help,
Marc
Thanks for reporting your progress and for adding the PHP code composing your $attr array. The syntax of the statement is fine and compiles correctly. There is one small error in your parameters; the 'mla_target' => 'blank' parameter should be 'mla_target' => '_blank'. The underscore is required for the HTML target attribute.
The $content parameter is optional; it contains the shortcode content when using the “enclosing shortcode” syntax. You can simply omit this parameter.
The page crash might be because the $wp_query->query_vars['photo_id'] element is not defined. You can try something like this:
if ( empty( $wp_query->query_vars ) ) {
echo 'query_vars not defined';
elseif ( empty( $wp_query->query_vars['photo_id'] ) ) {
echo 'photo_id not defined';
else {
$attr = ...
echo MLAShortcodes::mla_gallery_shortcode( $attr );
}
That should help identify any problems.
Hi
Thanks a lot!
Actually my tax_query was incorrect, it is supposed to be a multidimensional array, not a single one.
All fixed now!
Thanks again for your great support!
Good point – I looked at the syntax of the array statement but I didn’t investigate whether it was a valid WordPress tax_query. I regret any inconvenience caused by my incomplete response.
I am marking this topic resolved. Thanks for letting me know it’s working for you now.
