Problem: I would like to include a generic checkboxes field in my CRED form. Each post in a CPT should be shown as a checkbox.
Solution:
Use this format to create a generic checkboxes field that uses a View to provide each option:
[cred_generic_field field='provider-checkboxes-slug' type='checkboxes' class='' urlparam='']
{
"required":0,
"validate_format":0,
"default":[],
"options":[ [wpv-view name='providers-checkboxes-options-view-slug'] ]
}
[/cred_generic_field]
Use this format in your View to generate the proper options format:
<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 raw text output filter in PHP to clean up the output a bit further:
add_filter( 'wpv_filter_wpv_view_shortcode_output', 'prefix_clean_view_output', 5, 2 );
function prefix_clean_view_output( $out, $id ) {
if ( $id == '9999' ) { //Please adjust to your Views ID
$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 );
}
}
return $out;
}
Replace 9999 with your View ID.
