Hi there,
I want to use acf_form only for the form itself (to hook into validations, etc instead of having to code a custom form. Essentially, I want to use fields to complete other actions via acf/save_post (specifically running actions for an External, Third Party API like Salesforce based on the acf_form fields)
My form
$options = array(
'id' => 'my-id',
'post_id' => false,
'new_post' => false,
'post_title' => false,
'field_groups' => array(
1234
),
'submit_value' => 'Submit',
'uploader' => 'basic',
);
acf_form($options);
I am able to execute the third-party API functions with the above, however, the post where I’m embedding the above acf_form creates post_meta on that post. What I would like to do is prevent this from happening (I am currently just resetting/deleting all of the field values upon completion, but would like to know if there’s a better way.
Thanks in advance!
This has not been tested and I don’t know if it will work.
Use an acf/pre_save_post filter https://www.advancedcustomfields.com/resources/acf-pre_save_post/
You’ll need to implement some checking to make sure you’re dealing with the right form, and you’ll also need to look in $_POST['acf'] to get the values.
Once you’re done processing the form
unset($_POST['acf']);
ACF only begins the save process based on this having a value…. I think.
I’m not sure the above works anymore. I keep running into empty posts created and can only be deleted from the database.
The ACF method pre_save_post expects something numeric OR ‘new_post’ so what I do is pass neither of those things but instead 'post_id' => 'no_new_post' which seems to work. I also use acf/save_post hook at a priority less than 10 ( in my case 4 ).
I also get errors when unsetting $_POST['acf'] so I’ve been opting to use $_POST['acf'] = array();
Undefined index: acf in advanced-custom-fields-pro\includes\acf-form-functions.php on line 157
@howdy_mcgee I got that undefined index when I foolishly did do_action() instead of add_action(). Maybe you did the same.
acf/pre_save_post happens before the post is created.
Trying to do it on acf/save_post, no matter what priority you set, will always happen after the post is created.
