I have a new installation of WordPress (v.4.3.1) and Piklist v.0.9.9.7.

After adding values to my fields (I’ve tried editor, text, and file upload fields so far) and saving the post, the values will not update. I cannot change/delete any text or remove/uploaded images once the post has been saved.

Here Is The Test Code That I Am Using (copied straight from the Piklist plugin demo folder):

<?php
/*
Title: Editor Examples
Post Type: page
Order: 100
*/

  piklist('field', array(
    'type' => 'editor'
    ,'field' => 'post_content'
    ,'required' => true
    ,'label' => __('Post Content', 'piklist-demo')
    ,'description' => __('This is a replacement for the post_content editor', 'piklist-demo')
    ,'value' => 'Lorem ipsum dolor sit amet, consectetur adipiscing elit.'
    ,'options' => array(
      'wpautop' => true
      ,'media_buttons' => true
      ,'shortcode_buttons' => true
      ,'teeny' => false
      ,'dfw' => false
      ,'tinymce' => array(
        'resize' => false
        ,'wp_autoresize_on' => true
      )
      ,'quicktags' => true
      ,'drag_drop_upload' => true
    )
  ));

  piklist('field', array(
    'type' => 'text'
    ,'field' => 'text'
    ,'label' => __('Text', 'piklist-demo')
    ,'help' => __('You can easily add tooltips to your fields with the help parameter.', 'piklist-demo')
    ,'attributes' => array(
      'class' => 'regular-text'
    )
  ));

  piklist('field', array(
    'type' => 'file'
    ,'field' => 'upload_media'
    ,'scope' => 'post_meta'
    ,'label' => __('Media Uploader', 'piklist-demo')
    ,'options' => array(
      'modal_title' => __('Add File(s)', 'piklist-demo')
      ,'button' => __('Add', 'piklist-demo')
    )
  ));

?>

To make sure it wasn’t my theme, I’ve tried this code on the Twenty Fifteen theme and had all other plugins disabled. Another weird thing is that everything seems to be working fine if the fields are in a Group. I was successfully using the following code before I noticed the above mentioned issue:

<?php
/*
Title: Sections
Post Type: page
Order: 20
ID: 2
*/
  
?>

<div class="piklist-demo-highlight">
  <?php _e('Individual Homepage Sections', 'piklist-demo');?>
</div>

<?php

  piklist('field', array(
    'type' => 'group'
    ,'field' => 'sections'
    ,'label' => 'Homepage Sections'
    ,'columns' => 12
    ,'add_more' => true
    ,'fields' => array(
      array(
		'type' => 'colorpicker'
		,'field' => 'bg_color'
		,'label' => 'Background Color'
        ,'columns' => 12
      )
	  
      ,array(
		'type' => 'html'
		,'label' => __('<div style="width:100%; height:1px; background:#d1d1d1; margin-top:-10px; margin-bottom:-30px;"></div>', 'piklist-demo')
      )

      ,array(
		'type' => 'text'
		,'field' => 'title'
		,'label' => 'Section Title'
		,'help' => 'Leave blank if no section title is needed.'
        ,'columns' => 12
		,'attributes' => array(
			'class' => 'regular-text'
		)
      )
	  
      ,array(
		'type' => 'html'
		,'label' => __('<div style="width:100%; height:1px; background:#d1d1d1; margin-top:0px; margin-bottom:-30px;"></div>', 'piklist-demo')
      )
	  
      ,array(
		'type' => 'editor'
		,'field' => 'subtitle'
		,'label' => 'Subtitle'
		,'help' => 'Leave blank if no subtitle is needed. Multiple lines are allowed.'
		,'options' => array(
			'wpautop' => true
			,'media_buttons' => true
			,'shortcode_buttons' => true
			,'teeny' => false
			,'dfw' => false
			,'tinymce' => array(
				'resize' => false
				,'wp_autoresize_on' => true
			)
			,'quicktags' => true
			,'drag_drop_upload' => true
			)
		)
	  
      ,array(
		'type' => 'html'
		,'label' => __('<div style="width:100%; height:1px; background:#d1d1d1; margin-top:0px; margin-bottom:-30px;"></div>', 'piklist-demo')
      )

      ,array(
		'type' => 'select'
		,'field' => '_' . piklist::$prefix . 'relate_post'
		,'label' => 'Choose Page Content From'
		,'choices' => piklist(
			get_posts(array(
				'post_type' => 'page'
				,'numberposts' => -1
				,'orderby' => 'title'
				,'order' => 'ASC'
			))
			,array('ID', 'post_title')
		)
		,'relate' => array(
			'scope' => 'post'
		)
      )

    )
  ));

?>

I have recorded a screencast of what is happening if this helps. I will send it to piklist support.

Thanks
