Trying to add conditional display to blog-list

I have the list of posts (aka blog-list)
They currently display featured image, excerpt, and a read-more link.

I want to add the labels and values of the advanced custom fields to this display.

However, when I use the below code, it does not display the label (text) or the value (link) for anything and treats every entry as “!empty” despite many of the fields being empty.

<?php
$buttons = get_field_objects();
if( $buttons ) { ?>
  <div class="et_pb_button_module_wrapper et_pb_button_3_tb_body_wrapper">
    <?php foreach( $buttons as $button ) { ?>
      <?php if (!empty($button['value'])) { ?>
        <a class="vendor-link" title="<?php echo $button['label']; ?>" href="<?php echo $button['value']; ?>"><?php echo $field['label']; ?></a>
      <?php } ?>
    <?php } ?>
  </div>
<?php }?>

I would use get_field — except I want this to be a one time edit which pulls the data, even if I add or remove fields.
(the goal is to display a series of links, styled as buttons for each post in the list)

TYIA for any assistance you can provide

empty depends on what the value is.

https://www.php.net/manual/en/language.types.boolean.php#language.types.boolean.casting.

The values in the field object are the values before acf has formatted them (raw value), a true/false field set to false could be a string value "0" which is not empty.

Try get_fields() instead of get_field_objects() and then use get_field_object() for non empty fields to get the field label.

ok, trying again. This doesn’t display empty buttons… but seems to not display anything at all.

							$buttons = get_fields();
							if( $buttons ) { 
								echo
									'<div class="et_pb_button_module_wrapper et_pb_button_3_tb_body_wrapper">';
									foreach( $buttons as $but_name => $but_value ) {
										if( !empty( $but_value ) ) { 
											$but_label = get_field_object($but_name);
											echo
												'<a class="vendor-link" title="',$but_label['label'] ,'" href="', $but_value ,'">', $but_label['label'] ,'</a>';
										}
									}
								echo
									'</div>';
							}

Am I missing something obvious?

I don’t see anything obvious.

What is it getting?

$buttons = get_fields();
var_dump($buttons);

Ok, found the problem. I had to add the code in TWO placed within the theme template file….

This was my final working code – if anyone finds this in a future search

							/* START position for Advanced Custom Fields Content -- aka vendor-links */
							$buttons = get_fields();
							if( $buttons ) { 
								echo
									'<div class="button-strip et_pb_button_module_wrapper et_pb_button_3_tb_body_wrapper">';
									foreach( $buttons as $but_name => $but_value ) {
										if( !empty( $but_value ) ) { 
											$but_label = get_field_object($but_name);
											echo
												'<a class="vendor-link3 ', $but_name ,'-button" title="',$but_label['label'] ,'" href="', $but_value ,'" target="_blank">', $but_label['label'] ,'</a>';
										}
									}
								echo
									'</div>';
							}
							/* FINISH position for Advanced Custom Fields Content -- aka vendor-links */

I then used some CSS on “vendor-link3” and the button name (like amazon-button) to style them as buttons.

Thanks for the pointers John.
