This thread is resolved. Here is a description of the problem and solution.
Problem: I would like to filter the options shown in the Post Relationship field in the post editor screen. Only the current User's posts should be shown here.
Solution: There is not a good way to do this in wp-admin, but you can use generic fields in CRED to accomplish something similar.
- Create a CRED form to add posts and insert a generic select field
- Create a View of posts, filtered by author, where the author is the current User
- In the Loop Output editor, insert this code to replace the default wpv-loop tags:
<wpv-loop>
[wpv-item index=1]
{"value":"[wpv-post-id]","label":"[wpv-post-title]"}
[wpv-item index=other]
,{"value":"[wpv-post-id]","label":"[wpv-post-title]"}
</wpv-loop>
- Add the following custom code to your functions.php file:
add_filter( 'wpv_filter_wpv_view_shortcode_output', 'prefix_clean_view_output', 5, 2 );
function prefix_clean_view_output( $out, $id ) {
$ids = array( 12345 );
if ( in_array( $id, $ids )) {
$start = strpos( $out, '<!-- wpv-loop-start -->' );
if (
$start !== false
&& strrpos( $out, '<!-- wpv-loop-end -->', $start ) !== false
) {
$start = $start + strlen( '<!-- wpv-loop-start -->' );
$out = substr( $out , $start );
$end = strrpos( $out, '<!-- wpv-loop-end -->' );
$out = substr( $out, 0, $end );
} else {
$start = strpos( $out, '>' );
if ( $start !== false) {
$out = substr( $out, $start + 1 );
$end = strpos( $out, '<' );
$out = trim(substr( $out, 0, $end ));
}
}
}
return $out;
}
add_action('cred_save_data', 'cred_belongs_impresa_action',10,2);
function cred_belongs_impresa_action($post_id, $form_data)
{
$forms = array( 67890, 98765 );
// if a specific form
if (in_array($form_data['id'], $forms))
{
if (isset($_POST['selectcompany']))
{
update_post_meta( $post_id, '_wpcf_belongs_impresa_id', $_POST['selectcompany'] );
}
}
}
- Change 12345 to match the ID of the View
- Change 67890, 98765 to be a comma-separated list of CRED form IDs (your edit and add CRED forms)
- Place the View of posts inside the options of the generic select field:
[cred_generic_field field='your-field-slug' type='select' class='' urlparam='']
{
"required":0,
"validate_format":0,
"default":[],
"options":[ [wpv-view name="your-parent-post-view-slug"] ]
}
[/cred_generic_field]

It looks like the CRED form was changed to edit "Articoli" instead of the Opportunita Imprese CPT. This is why the "Modifica" links were not appearing. I changed that and now the links are back. So please check it out and let me know if you're ready to move to the next step, which is saving the parent post reference when the CRED form is submitted.
As you can see it doesn't seem to work. I added it as you wrote it. Do I have to change anything?
I tried adding a new child post but the company wasn't saved. Is the function you had me add to functions.php the same for both? Shouldn't I be adding a similar function for the adding process? The cred form ids are different. In fact you had me change the 9999 to the add post cred form id, in the previous post.
add_action('cred_save_data', 'cred_belongs_impresa_action',10,2);
function cred_belongs_impresa_action($post_id, $form_data)
{
$forms = array( 196, 9999 );
// if a specific form
if (in_array($form_data['id'], $forms))
{
if (isset($_POST['selectcompany']))
{
update_post_meta( $post_id, '_wpcf_belongs_impresa_id', $_POST['selectcompany'] );
}
}
}
I changed 9999 to 230, which is the id of the edit cred form, so I thought that for the adding process, there would be a similar function with different parameters...
