foreach loop is not showing all results (woocommerce variation dropdown) - php

Question

I am trying to customize the variations dropdown on the product page using the answers here:
Add the variation price to variable product dropdown item names in Woocommerce
function wiz_rebuild_variation_dropdown( $html, $args ) {
// Only if there is a unique variation attribute (one dropdown)
if( sizeof($args['product']->get_variation_attributes()) == 1 ) :
$options = $args['options'];
$product = $args['product'];
$attribute = $args['attribute'];
$show_option_none = $args['show_option_none'] ? true : false;
$show_option_none_text = $args['show_option_none'] ? $args['show_option_none'] : __( 'Choose an option', 'woocommerce' );
if ( empty( $options ) && ! empty( $product ) && ! empty( $attribute ) ) {
$attributes = $product->get_variation_attributes();
$options = $attributes[ $attribute ];
}
// Build the Select container
$html = '<select id="something">';
$html .= '<option value="something">' . esc_html( $show_option_none_text ) . '</option>';
if ( ! empty( $options ) ) {
foreach ( $options as $option ) {
// print_r($option);
$html .= '<option value="'. esc_html( $option ) . '">something</option>';
}
}
// Close the Select container
$html .= '</select>';
endif; // More than one attributes (multiple pulldowns) - code not executed
return $html;
}
add_filter( 'woocommerce_dropdown_variation_attribute_options_html', 'wiz_rebuild_variation_dropdown', 10, 2);
Somehow the dropdown will not show more than one tag. I have checked the array and there are 4 results (print_r in the foreach). If I comment out the 'Choose an option' option, the first result in the foreach will show, but not the other three. Is something going wrong with appending the $html variable?
I'm getting dizzy from trying :-/
Can anyone see what I am doing wrong here?

Thanks to all for the great help through the years!

Answer 1

So I found out what the problem was. Looks like this pulldown will not function without the correct name attribute in the SELECT tag.
by catching that like in the original example (see URL):
$name = $args['name'] ? $args['name'] : 'attribute_' . sanitize_title( $attribute );
and adding it to the SELECT:
name="' . esc_attr( $name ) . '"
the script adds the required class names to the option tags automatically and image/price changes function as well.
Thanks for the tips, guys! Pff.. one step made today :))
