Hello,

I wish to use a repeater field in a form and get the values after the submission. I can acess at normal fields but not to repeaters, I don’t find the correct syntaxe, could you help me ?

Here is my code

add_action('genesis_entry_content', 'tsm_do_acf_form_content');
function tsm_do_acf_form_content() {
	
    $new_ticket = array(
		'field_groups'       => array('group_5781107cb5e71'), // Create post field group ID(s)
		'form'               => true,
		'html_before_fields' => '',
		'html_after_fields'  => '',
		'submit_value'       => 'Poster',
		'updated_message'    => 'Votre ticket a été créé.'
    );
    acf_form($new_ticket);
}

// Update existing post data
add_filter('acf/pre_save_post' , 'tsm_do_pre_save_post' );
function tsm_do_pre_save_post($post_id) {

	$repeater_field = 'repeater';
	$repeater_key = $_POST['acf']['field_5781197cd6ebr'];
	$sub_field_start = 'sub_field';
	$sub_field_start_key = 'field_5769116be53524';
	$sub_field_end = 'sub_field';
	$sub_field_end_key = 'field_5745116be9824';

	$ticket_date = 'Ticket';
	if( have_rows($repeater_field, $repeater_key) ):

		// loop through the rows of data
		while ( have_rows($repeater_field, $repeater_key) ) : the_row();
			$ticket_date = 'Ticket 2';
			// display a sub field value
			$ticket_date .= '<p> Start date '  . $sub_field_start_key ;
			$ticket_date .= ' End date '  . $sub_field_end_key . '</p>';
			
		endwhile;
	else :
		$ticket_date = "No ticket";
	endif;

}

Its always show “No ticket”

Hi @jacquesmivi

I’m afraid I don’t understand your setup. Could you please tell me what you want to do with the $ticket_date variable?

Regarding your issue, could you please check the value of the $repeater_key variable? Please keep in mind that the second parameter of the have_rows() function should be the post ID, so it will make more sense if you use it like this:

if( have_rows($repeater_field, $post_id) ):

Also, the acf/pre_save_post is executed before any saving process. If you need to do it after the data is saved, you need to use the acf/save_post hook with a priority of 20 instead. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/acfsave_post/.

I hope this makes sense 🙂

Thanks for your answer.

I have a form to pick one or * dates (repeater field), and i wish to send this by email.
So I try to construct ‘$ticket_date’ with the different walues.

If I send “$_POST[‘acf’][‘field_5781107cd6eaa’]” I just have “Array” in my email.
If I send have_rows($_POST[‘acf’][‘field_5781107cd6eaa’]) I got nothing in my email.

Hi @jacquesmivi

That’s because the repeater is posted as an array. If you want to see the values of the array, please try this code:

$ticket_date = print_r($_POST['acf']['field_5781107cd6eaa'], true);

To learn how to use an array, please take a look at this page: http://php.net/manual/en/language.types.array.php.

I hope this helps 🙂
