Add Repeater Row From Another Field

Hi there,

I have a front end form using acf_form() where I’d like front-end users to add a row to a repeater from a textarea. In other words, I don’t want users to be able to edit/change rows, only add them via a textarea field (and then reset said textarea)

I’ve checked out add_row() and suppose that this needs to be used in conjunction with acf/save_post

My code:

function add_repeater_row_on_save($post_id) {	
	
	$my_textarea = get_field('my_textarea'); // My textarea field
			
	$row = array(  // my repeater sub-field
		'field_1s'	=> 'Repeater sub-field 1 text',
		'field_2S'	=> 'Repeater sub-field 2 text',
		'field_3s'	=> 'Repeater sub-field 3 text',
	);
	
	$i = add_row('field_repeater', $row);
	
	// Default Meta Key Array
	$reset_textearea_value = array(
		'my_textarea' => '',
	);

	
	// Set Default Meta Keys Loop
	foreach($reset_textearea_value as $meta_key => $meta_value) {
	   update_post_meta($post_id, $meta_key, $meta_value);
	};
	
};
add_action('acf/save_post', 'add_repeater_row_on_save', 20);

The above code does update my textarea, just not the repeater bit.

Thanks in advance for any insights!

Sigh, sometimes I feel like when I post here, the solution is about 5 minutes away. Turns out that I was missing the $post_id in the add_row() function.

So, the code that I have and is now working is:

function add_repeater_row_on_save($post_id) {	
	
	$my_textarea = get_field('my_textarea'); // My textarea field
			
	$row = array(  // my repeater sub-field
		'field_1s'	=> 'Repeater sub-field 1 text',
		'field_2S'	=> 'Repeater sub-field 2 text',
		'field_3s'	=> 'Repeater sub-field 3 text',
	);
	
	$i = add_row('field_repeater', $row,$post_id); // The $post_id here was missing
	
	// Reset Textarea
	update_field('my_textarea', '', $post_id);
	
};
add_action('acf/save_post', 'add_repeater_row_on_save', 20);
