Hello,

I have a CPT called Pack (slug label), I have setup a taxonomy called Label (slug label), the taxonomy is attached to the CPT Pack(pack) and Media(attachment) via the UI of Metabox (Tab taxonomy).

Then I setup a custom field using the UI Tab Custom Fields. The field group ID is 'taxonomy_add', the field type is 'image advanced', the ID is 'label_image_upload', max number of file '1', ticked 'show as admin column', in the settings I have picked the Location 'Taxonomy' and Label(label).

With this setup it is possible to upload one image to the taxonomy 'label', the uploaded image is displayed in the admin edit screen of the taxonomy 'label'. so far so good !

CPT : pack
taxonomy : 'label' is attached to CPT 'pack' and Media
field group of custom field : taxonomy_add is attached to taxonomy 'label'
ID custom field : label_image_upload

I am using the oxygen page builder, the following code works halfway in the repeater (in a codeblock)
the first 4 attached images to the CPT 'pack' are shown (those images have nothing to do with the taxonomy 'label', those were attached via the admin media screen).

I have written in between the code, can you pls pls help me with this ?
```
<?php 
  if($images = get_children(array(
  	'post_parent'    => get_the_ID(),
  	'post_type'      => 'attachment',
  	'numberposts'    => 4, // show all 
	'post_status' 	 => 'published',
	'post_mime_type' => 'image',
  	'order'			=> 'asc'
	))) {

  foreach($images as $image) {
	  echo wp_get_attachment_image($image->ID, array('70','90'));
	}}

    // WORKS GOOD UNTIL HERE - 4 Attachments are shown

   // FROM HERE ON, I WANT TO CRY :-(

  //Getting the term by name
          $terms = get_the_terms($post->ID, 'taxonomy_add');
// used print_r and var_dump with $terms -> invalid taxonomy and additional_data:protected
			
  //Retrieving images from taxonomy by term id
        foreach($terms as $term) {
             $image_id = get_term_meta($term->term_id, 'label_image_upload', true);
        echo '<img src=' . $image_id . '>';
}
   ?>
```

So far I have accomplished this
```
<?php
//Getting the term by name
$terms = get_the_terms($post->ID, 'label'); 
		  
		  print_r ( $terms );

//Retrieving images from taxonomy by term id
foreach($terms as $term) {
	
	echo $term->term_id;
?>
```
the print_r($terms) function gives me the following:

Array ( [0] => WP_Term Object ( [term_id] => 53 [name] => Dog Art [slug] => dog-art [term_group] => 0 [term_taxonomy_id] => 53 [taxonomy] => label [description] => [parent] => 0 [count] => 7 [filter] => raw ) ) 53

which is great because this is the label, that is attached to the CPT, the term_id is also correct

now I just need the image ...
How do I get to the image of the custom field ?

Hi Joe,

If you use the field type image_advanced, you also need to use a loop to iterate through an array of image IDs. If you just want to upload 1 image, you can use the field single_image to simply get the image ID. Please read more on the documentation
https://docs.metabox.io/fields/image-advanced/#template-usage
https://docs.metabox.io/fields/single-image/#template-usage

And this documentation to get the term meta
https://docs.metabox.io/extensions/mb-term-meta/

Hi,

just found out how it works, if you have a better solution, please let me know :
```
<?php
//$terms = get_the_terms($post->ID, array('label', 'week', 'formate', 'pack'),
$terms = get_the_terms($post->ID, array('label'),
					   array(
                        'hide_empty'    => true,
					    'posts_per_page'   => null
                    )
            );
		  
foreach($terms as $term) {
	
	$image_id = get_term_meta($term->term_id, 'label_image_upload', true);
	$image_url = wp_get_attachment_image_src($image_id, 'full');
?>
	<img src="<?php echo $image_url[0]; ?>" width="<?php echo $image_url[1]; ?>" height="<?php echo $image_url[2]; ?>" />
<?php
}
?>
```

Hi,

The code is correct to display the term meta image on the frontend. It is the same as mentioned in the documentation https://docs.metabox.io/extensions/mb-term-meta/#getting-field-value
