I know that you can choose Post Object, or Post ID, so specifically this means that it will be either an array or ID? So if I wanted to put a specific ID into the field would I be able to create a variable and place that ID into the field?
So as an example…
<?php
function store_relationship_id( $args ) {
echo '<input type="hidden" name="relationship_field" value="MyValue"';
}
add_action( 'acf/input/form_data', 'store_relationship_id', 10, 1 );
?>
Will this get stored correctly?
The Relationship field holds an array of post IDs. I don’t think you can add a hidden field and do this, ACF uses the field IDs in the form and the posted data all in the “acf” index of $_POST.
I think you need to create an acf/save post filter to add posts to the relationship field. http://www.advancedcustomfields.com/resources/acfsave_post/
So if I’m understanding this hook correctly I’d be able to do something like this:
<?php
function my_acf_save_post( $project_id ) {
// bail early if no ACF data
if( empty($_POST['acf']) ) {
return;
}
//obtain the current page's post ID
$project_id = get_the_ID();
// array of field values
$fields = $_POST['acf'];
// specific field value
$field = $_POST['acf']['assigned_project'];
}
// run before ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 1);
// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 20);
?>
And $project_id would be stored in the ‘assigned_project’ acf field?
Thanks, after looking over a few more documents and other examples I was able to figure it out! Really great plugin, makes application creation very easy for me.
Sorry I didn’t get back about to you on your follow up, glad you got it worked out.
That’s what I use ACF for, application development. WP is a good base to start with and ACF really helps with making it into a real CMS.
