Hi,

I am trying to display the contents of an advanced ‘add-more’ using a Piklist plugin. This add-more does not contain any further nested add-mores, just a few fields. I read the docs, and I think I do understand the concept of having a separate template file for each ‘add-more level’. However, I’m still running into issues and errors.

The code that generates the metabox is the following.

<?php
/*
Title: My Piklist Test
Description: My Description
Post Type: piklist_test
Order: 1
Lock: true
Collapse: true
*/

piklist('field', array(
   'type' => 'group'
  ,'field' => 'piklist_test_addmore'
  ,'add_more' => true
  ,'fields' => array(

array(
   'type' => 'text'
  ,'field' => 'piklist_test_title'
  ,'label' => __('Title','piklist')
  ,'description' => __('Enter a title for this test.','piklist')
  ,'help' => __('Enter a title for this test.','piklist')
  ,'attributes' => array(
    'class' => 'large-text'
    ,'placeholder' => __('Enter title here','piklist')
  )
  ,'on_post_status' => array(
    'value' => 'lock'
  )
  ,'sanitize' => array(
  array(
    'type' => 'title'
    ,'context' => 'save'
  )
)
)
,array(
  'type' => 'editor'
  ,'scope' => 'post'
  ,'field' => 'piklist_test__content'
  ,'label' => __('Test Content','piklist')
  ,'description' => __('Enter content for this test.','piklist')
  ,'help' => __('Enter content for this test','piklist')
  ,'value' => '<h1>Headline.</h1><p>Some text here.</p>'
  ,'options' => array (
    'wpautop' => false
    ,'media_buttons' => true
    ,'tinymce' => true
    ,'quicktags' => true
  )
)

,array(
  'type' => 'file'
  ,'field' => 'piklist_test_media'
  ,'scope' => 'post_meta'
  ,'label' => __('Add Media','piklist')
  ,'description' => __('Add media for this test.','piklist')
  ,'help' => __('Add media for this test','piklist')
  ,'options' => array(
    'modal_title' => __('Add Test Media','piklist')
    ,'button' => __('Add Media','piklist')
  )
  ,'validate' => array(
    array(
      'type' => 'limit'
      ,'options' => array(
        'min' => 1
        ,'max' => 1
      )
    )
  )
)

,array(
  'type' => 'colorpicker'
  ,'scope' => 'post_meta'
  ,'field' => 'piklist_test_color'
  ,'label' => __('Test Color','piklist')
  ,'description' => __('Select a color for this test','piklist')
  ,'help' => __('Select a background color for this test','piklist')
  ,'attributes' => array(
    'class' => 'text'
  )
)

,array(
  'type' => 'select'
  ,'field' => 'piklist_test_option'
  ,'value' => 'option-1' // Sets default to option-1
  ,'label' => __('Test Layout','piklist')
  ,'description' => __('Choose an option for this test','piklist')
  ,'attributes' => array(
    'multiple'
  )
  ,'choices' => array(
    'option-1' => __('Option 1','piklist')
    ,'option-2' => __('Option 2','piklist')
  )
)

)
));

Next, I created a template file called test_template.php which I placed in the parts directory of my plugin which for now simply includes the following.

<?php echo $data['piklist_test_title']; ?>

I then opened up my theme’s folder, created a file called single-test.php and I placed the following content in the WP loop (just before the_content()).

<?php

	// Get the post meta information
	$piklist_test_addmore = get_post_meta($post->ID, 'piklist_test_addmore', true);
		 
	// 1. Display the data using the file test_template.php.
	// 2. Assign your $piklist_test_addmore parameter (from above) to 'data'.
	// 3. Loop through 'data'.
	piklist('test_template', array('data' => $piklist_test_addmore, 'loop' => 'data'));
?>

I’m not sure what I’m doing incorrectly, but I’m getting the following errors in the front-end (when viewing a single test).

Warning: array_keys() expects parameter 1 to be array, string given in C:\xampp\htdocs\wp-content\plugins\piklist\includes\class-piklist.php on line 827

Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\wp-content\plugins\piklist\includes\class-piklist.php on line 256

Notice: Undefined index: slide-name in C:\xampp\htdocs\wp-content\plugins\piklist-test\parts\test_template.php on line 1

Any ideas as to what I may be doing incorrectly?

Many thanks,
Ian
