Insert custom additional attributes to an input field

Hello @rierajf

Thank you very much for using our plugin. Yes, that’s possible, but it requires to use the plugin events.

I’ll try to describe the process with a hypothetical example.

Assuming you have the checkbox field:

<label>Posts</label>
[checkbox posts use_label_element]

And you want to populate it with the list of website posts, using the post ID as checkbox values and post_title as their texts, and additionally, you want to fill their data-prix attributes with the posts authors’ ids.

Enter the following form structure:

<label>Posts</label>
[checkbox posts use_label_element]

[cf7-recordset id="post-db" type="database" query="SELECT ID, post_author, post_title FROM {wpdb.posts}"]
[cf7-link-field recordset="post-db" field="posts" value="ID" text="post_title"]

<script>
jQuery(document).on('change', '[name="posts[]"]', function(evt, attr){
    if(attr == 'cf7-ds-fill') {
        let list = cf7_datasource_get_recordset_data('post-db');
        for(let i in list) {
            jQuery('[name="posts[]"]:eq('+i+')').attr('data-prix', list[i]['post_author']);
        }
    }
});
</script>

The event is triggered after filling in the checkbox choices. It walks through the recordset records and assigns the data-prix attribute to the checkboxes with post_author information.

Best regards.
