Displaying WordPress Post Images

Question

I deduced in WordPress an array with id pictures:

var_dump ($gt3_theme_pagebuilder["post-formats"]["images"]);

Conclusion:

 array(3) { [78]=> array(1) { ["attach_id"]=> string(4) "1739" } [279]=> array(1) { ["attach_id"]=> string(4) "2457" } [280]=> array(1) { ["attach_id"]=> string(4) "2458" } }

Now I want to display pictures of all the photos by their ID:

 foreach ($gt3_theme_pagebuilder as $key => $foto_id) { wp_get_attachment_image ($foto_id); }

This code does not work. What am I doing wrong?

You yourself led the structure of the variable ...

At the input of the wp_get_attachment_image() function, an integer is expected, and you are passing an array. You think that the $foto_id variable in your loop contains the ID of the photo, and in fact there is an array of the form ["attach_id" => "1739"] . To get the ID, you need to access it by the key attach_id .

Here is the corrected code:

 $gt3_theme_pagebuilder = [ 78 => [ "attach_id" => "1739" ], 279 => [ "attach_id" => "2457" ], 280 => [ "attach_id" => "2458" ] ]; foreach ($gt3_theme_pagebuilder as $key => $foto) { wp_get_attachment_image($foto['attach_id']); }

I put the right pictures on the post page, everything is as it should, but now you need to make a slider gallery and zoom effect with a click on it, do you have any ideas?) Plugins ready for WP lightbox 2 do not work, here is the site on get pagebuilder and it displays pictures outside the box, therefore rewrite plugin, theme, etc.
