Here’s what I think is the complete rundown:

I’m using this URL:

/testing/?image_id=8324

There’s nothing on that page except for:

[test_shortcode]

And just to confirm I’m using the correct field name, here’s the source code of the field in the backend when editing an image:

<tr class="acf-field acf-field-number acf-field-64e143e0efab0" data-name="image_meta_image_id" data-type="number" data-key="field_64e143e0efab0">
<td class="acf-label">
<label for="acf-field_64e143e0efab0">Image ID</label></td>
<td class="acf-input">
<div class="acf-input-wrap"><input type="number" id="acf-field_64e143e0efab0" name="acf[field_64e143e0efab0]" value="8324" step="any"></div></td>
</tr>

And here’s the complete shortcode:

function get_test_shortcode() {
  $image_meta_image_id = $_GET["image_id"];
  // echo $image_meta_image_id;
  // *********************** FROM ACF FORUM 09-01-2023 ***********************
  // first you do a query for attachments looking for the exact image_meta_image_id
  $args = array(
      'fields' => 'ids', // return only IDs to use in the next query
      'posts_per_page'    => 1, // there should only be one image
                                // with this "image_meta_image_id"
      'post_type'      => 'attachment',
      'meta_query'    => array(
    		array(
    			'key'	 	=> 'image_meta_image_id',
    			'value'	  	=> $image_meta_image_id
    		)
    	)
  );
  $attachment_query = new WP_Query( $args );
  $attachments = $attachment_query->posts();

echo "<pre>";
  var_dump( $attachments );
echo "</pre>";

}
add_shortcode( 'test_shortcode', 'get_test_shortcode' );

The only thing showing on the page is the page title TESTING and bool(false).

Do you see anything amiss?

Thanks again!!
