Have rows (ACF)

The function have_rows checks to see if a parent field (such as Repeater or Flexible Content) has any rows of data to loop over. This is a boolean function, meaning it returns either true or false.

This function is intended to be used in conjunction with the_row() to step through available values.

Using have_rows() together with the_row() is intended to feel native much like the have_posts() and the_post() WordPress functions.

Syntaxis

have_rows( $selector, [$post_id = false] ); as boolean - True if row exists

• $selector(string, required): Veldnaam of veldsleutel
• $post_id (mixed, optional): Post-ID. Voor items op pagina Options, moet dit option zijn.

Voorbeeld: Heeft deze repeater subvelden?

if (have_rows('add_code_to_head', 'option'))
{
	echo "It has rows!";
}
