WPForms: Submit the form only once for logged in users.

wpforms-submit-form-once-loggedin.php

<?php

add_action( 'wp', function () {
	if ( ! is_user_logged_in() ) {
		return;
	}

	$entries = wpforms()->entry->get_entries(
		array(
			'form_id' => 74, // CHANGE THIS FORM ID
			'user_id' => get_current_user_id(),
		),
		true // count values only, we don't need actual data
	);

	// We allow to fill the form only once.
	if ( $entries >= 1 ) {
		add_action( 'wpforms_frontend_output_before', function () {
			echo '<p>You have already submitted this form.</p>';
		} );
		add_action( 'wpforms_frontend_load', '__return_false' );
	}
} );

made my day thanks!

im soory for the newb question, but where do i put this code? inside themes functions.php? or somewhere else?

@Maks1983, here is a blog article that has all the details about where and how to put a code snippet to make it work: https://www.wpbeginner.com/plugins/how-to-easily-add-custom-code-in-wordpress-without-breaking-your-site/
Please note, this code snippet works only with a paid version of the WPForms plugin because entries storage is available only from the Basic license (not available in WPForms Lite).

You can also consider upgrading to WPForms Pro to get access to Form Locker addon with a lot more features, as well as many others addons. Also, the Black Friday deal is coming ;)

@slaFFik, thank you very much. Love you

hi,
I tried this code in three wp code snippet plugins, but in all of them, one form can be sent multiple times.
please guide me.

hi,

I tried this code in three wp code snippet plugins, but in all of them, one form can be sent multiple times. Or it locks other forms and does not allow sending other forms
please guide me.
