Support » Plugins » Dynamic list of radio options in custom field

  • I am trying to add a custom field radio group to one of my custom post types and ma hitting wall after wall. Here’s what I would like to occur:

    On my CPT “service” I would like to show a list of specific items from the media library that have a certain custom field marked as true. Each of these media items should display as a radio option. I can create the queries and stuff but can’t seem to create options for the radio group that are anything but static. By this I mean I can manually enter values as options just fine. But I cannot for the life of me get it to just automatically grab all the appropriate posts and use each as an option.

    I can post the code I’m using if anyone would like. I was just wondering if there was anyway to modify my array so that options are dynamic and not static as in:

    $meta_box['service'] = array(
        'id' => 'service-info',
        'title' => 'Service info',
        'context' => 'normal',
        'priority' => 'high',
        'fields' => array(
            array(
                'name' => 'Service background',
                'desc' => 'The background for this service',
                'id' => 'service-bg',
                'type' => 'radio',
    	'options' => array(
                    array('name' => ?????, 'value' => ??????)
                )
            )
        )
    );

    Here is the full code right now. Kind of messy I know:

    $attachments = get_posts( array(
    			'post_type' => 'attachment',
    			'posts_per_page' => -1,
    			'meta_key'         => '_kjm_is_service',
    			'meta_value'       => '1'
    		) );
    		            if ( $attachments ) {
    			foreach ( $attachments as $attachment ) {
    
    			$kjm_alt = get_post_meta($attachment->ID, '_wp_attachment_image_alt', true);
    			$kjm_image_title = $attachment->post_title;
    			$kjm_url = wp_get_attachment_url( $attachment->ID , false );
    			}
    			}
    
    $meta_box['service'] = array(
        'id' => 'service-details',
        'title' => 'Service Details',
        'context' => 'normal',
        'priority' => 'high',
        'fields' => array(
            array(
                'name' => 'background-image',
                'desc' => 'bla bla bla',
                'id' => 'service-bg',
                'type' => 'radio',
    	'options' => array(
                    array('name' => 'Name 1', 'value' => 'Value 1'),
                    array('name' => 'Name 2', 'value' => 'Value 2'),
                    array('name' => $kjm_url, 'value' => $kjm_url)
                )
            )
        )
    );
    
    add_action('admin_menu', 'kjm_add_box');
    
    //Add meta boxes to post types
    function kjm_add_box() {
        global $meta_box;
    
        foreach($meta_box as $post_type => $value) {
            add_meta_box($value['id'], $value['title'], 'kjm_format_box', $post_type, $value['context'], $value['priority']);
        }
    }
    
    //Format meta boxes
    function kjm_format_box() {
      global $meta_box, $post;
      //print_r(array_values($meta_box));
      // Use nonce for verification
      echo '<input type="hidden" name="kjm_meta_box_nonce" value="', wp_create_nonce(basename(__FILE__)), '" />';
    
      echo '<table class="form-table">';
    
      foreach ($meta_box[$post->post_type]['fields'] as $field) {
          // get current post meta data
          $meta = get_post_meta($post->ID, $field['id'], true);
    
    		     echo '<tr>'.
                  '<th style="width:20%"><label for="'. $field['id'] .'">'. $field['name']. '</label></th>'.
                  '<td>';
          switch ($field['type']) {
    
              case 'radio':
                  foreach ($field['options'] as $option) {
    
                      echo '<input type="radio" name="' . $field['id'] . '" value="' . $option['value'] . '"' . ( $meta == $option['value'] ? ' checked="checked"' : '' ) . ' />' . $option['name'];
                  }
                  break;
    
                  }
          }
          echo     '<td>'.'</tr>';
      }
    
      echo '</table>';
    
    }
    
    // Save data from meta box
    function kjm_save_data($post_id) {
        global $meta_box,  $post;
    
        //Verify nonce
        if (!wp_verify_nonce($_POST['kjm_meta_box_nonce'], basename(__FILE__))) {
            return $post_id;
        }
    
        //Check autosave
        if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
            return $post_id;
        }
    
        //Check permissions
        if ('page' == $_POST['post_type']) {
            if (!current_user_can('edit_page', $post_id)) {
                return $post_id;
            }
        } elseif (!current_user_can('edit_post', $post_id)) {
            return $post_id;
        }
    
        foreach ($meta_box[$post->post_type]['fields'] as $field) {
            $old = get_post_meta($post_id, $field['id'], true);
            $new = $_POST[$field['id']];
    
            if ($new && $new != $old) {
                update_post_meta($post_id, $field['id'], $new);
            } elseif ('' == $new && $old) {
                delete_post_meta($post_id, $field['id'], $old);
            }
        }
    }
    
    add_action('save_post', 'kjm_save_data');

    The data does save but this currently just returns the first two static options plus one with the most recent URL from the $attachments query.
