Hello,

I try to update a CPT with a front end form.

I call my form with an URL like this:

http://xxx.com/my-form/?action=presentation&_post[ID]=57

And this is the code from my form file:

<?php
/*
Method: post
*/

piklist( 'field', 
                array(
                        'type'  => 'hidden',
                        'scope' => 'post',
                        'field' => 'post_type',
                        'value' => 'presentation',
                )
);

piklist( 'field', 
                array(
                        'type'          => 'text',
                        'scope'         => 'post',
                        'field'         => 'post_title',
                        'label'         => esc_html__( 'Title' , 'katt' ),
                )
);

piklist( 'field', 
                array(
                        'type'          => 'textarea',
                        'scope'         => 'post',
                        'field'         => 'post_content',
                        'label'         => esc_html__( 'Content' , 'katt' ),
                        'attributes' 	=> array(
        					   'rows' => 10,
        					   'cols' => 50,
        					   'class' => 'katt-proposition-content',
										 )
                )
);

piklist( 'field', 
                array(
                    'type'              => 'submit',
                    'field'             => 'submit',
                    'value'             => esc_html__( 'Submit' , 'katt' ),
                    'attributes'        => array(
                                                'class' => 'button button-primary',
                                        )
                )
);

1- My inputs form are empty and not populated by the id=57 “presentation” CPT data.
Do I need to do it myself with a get_post_type($args) function or Piklist is supposed to do it itself?
If I put some content in the (empty) fields and submit the form, my id=57 CPT is updated. However, the front end input fields remain empty.

2- Have got some warning messages on each fields (Mode debug > true)
Warning: Illegal string offset ‘field’ in /xxx/wp-content/plugins/piklist/includes/class-piklist-form.php on line 926
