Not having luck displaying repeater fields

  • Hi there,
    I’m using ACF 4.4.5 and am having a little trouble getting this plugin to work. First of all, after creating a custom widget area, in the Location Rules I never get my custom-named widget available in the 3rd box. It’s always a generic widget called “Widget”. However, so long as I assign the right field group ID to the widget itself, the fields appear in admin correctly.

    But I’m using a repeater field here. I’ve tried the following code, and can’t get anything to print, let alone list properly:

    <div class="exampleWidget">

	<h3>This is our example widget</h3>

	<p>We can grab field values like this:</p>

	<?php
				// check for rows (sub repeater)
				if( have_rows('select_products', 218) ):
			?>

			<ul class="fa-ul">
				<?php
					// loop through rows (sub repeater)
					while( have_rows('select_products', 218) ): the_row();
						print_r(get_field('product_name', 218));
					// display each item as a list - with a class of completed ( if completed )
				?>
				<li><i class="fa-li fa fa-download"></i><?php the_sub_field('product_name', 218); ?></li>

				<?php endwhile; ?>
			</ul>

			<?php endif; //if( get_sub_field('documents') ): ?>

    </div>

    Not sure what I’m doing wrong. I’ve tried using $widget_id instead of the actual ID of 218, and still nothing. Help!

    Please use the prefilled $widget_id variable.

    So when you want to retrieve a field use:

    get_field( 'field_name', $widget_id );

    So your example would be:

    <div class="exampleWidget">

	<h3>This is our example widget</h3>

	<p>We can grab field values like this:</p>

	<?php if ( get_field( 'select_products', $widget_id ) ) : ?>
		<ul class="fa-ul">
			<?php while ( has_sub_field( 'select_products', $widget_id ) ) : ?>
				<li>
					<i class="fa-li fa fa-download"></i>
					<?php the_sub_field( 'product_name' ); ?>
				</li>
			<?php endwhile; ?>
		</ul>
	<?php endif; ?>

</div>

    Yeah, like I said, I’d tried that to no avail before. I’ve just used your code, and still nothing displays at all.

    Perhaps it’s a problem with the functions.php code?

    class DNF_Product_Slider_Widget extends ACF_Widget
{
	function __construct()
	{
		$widget_options = array(
			"classname"     => "dnf_product_slider_widget",
			"description"   => "Widget with image, title and a link."
			);

		parent::WP_Widget("DNF_Product_Slider_Widget", "DNF Product Slider", $widget_options);

		// This is the Group ID which will be preset in your custom widget
		$this->acf_group_id     = 218;

		// Want to show a title in the widget box, please fill in your title field key
		$this->title_field_key  = "title";
	}

	function widget($args, $instance)
	{
 		// Variables
		$acf_key = "widget_" . $this->id_base . "_" . $this->number;

		// Widget HTML output
		include(realpath(dirname(__FILE__)) . "/blocks/product-slider-widget.php");
	}
}

$GLOBALS["acf_widget_types"][] = "dnf_product_slider_widget";
register_widget("DNF_Product_Slider_Widget");

    And I’ve modified the markup inside product-slider-widget.php thusly:

    <div class="exampleWidget">

	<h3>This is our example widget</h3>

	<p>We can grab field values like this:</p>

	<?php if ( have_rows( 'select_products', $widget_id ) ) : ?>
		<ul class="fa-ul">
			<?php while ( have_rows( 'select_products', $widget_id ) ) : ?>
				<li>
					<i class="fa-li fa fa-download"></i>
					<?php the_sub_field( 'product_name' ); ?>
				</li>
			<?php endwhile; ?>
		</ul>
	<?php endif; ?>

</div>
