How to overwrite "wc_display_item_meta" function in WooCommerce - php

Question

I am looking to have an action included in my functions.php file that changes the echo array from true to false in the below code:
function wc_display_item_meta( $item, $args = array() ) {
$strings = array();
$html = '';
$args = wp_parse_args(
$args,
array(
'before' => '<ul class="wc-item-meta"><li>',
'after' => '</li></ul>',
'separator' => '</li><li>',
'echo' => true,
'autop' => false,
'label_before' => '<strong class="wc-item-meta-label">',
'label_after' => ':</strong> ',
)
);
The above code is found in the WooCommerce wc-template-functions.php file found on line 3273.
How can I do this?

Answer 1

In includes/wc-template-functions.php, you will see that the function in there is wrapped in a if ( ! function_exists( 'wc_display_item_meta' ) ) { conditional.
So redefine the same function in functions.php file of the active child theme (or active theme) and your custom function will override the existing.
Note: A function can only be reassigned this way once.
So you get:
/**
* Display item meta data.
*
* #since 3.0.0
* #param WC_Order_Item $item Order Item.
* #param array $args Arguments.
* #return string|void
*/
function wc_display_item_meta( $item, $args = array() ) {
$strings = array();
$html = '';
$args = wp_parse_args(
$args,
array(
'before' => '<ul class="wc-item-meta"><li>',
'after' => '</li></ul>',
'separator' => '</li><li>',
'echo' => false,
'autop' => false,
'label_before' => '<strong class="wc-item-meta-label">',
'label_after' => ':</strong> ',
)
);
foreach ( $item->get_formatted_meta_data() as $meta_id => $meta ) {
$value = $args['autop'] ? wp_kses_post( $meta->display_value ) : wp_kses_post( make_clickable( trim( $meta->display_value ) ) );
$strings[] = $args['label_before'] . wp_kses_post( $meta->display_key ) . $args['label_after'] . $value;
}
if ( $strings ) {
$html = $args['before'] . implode( $args['separator'], $strings ) . $args['after'];
}
$html = apply_filters( 'woocommerce_display_item_meta', $html, $item, $args );
if ( $args['echo'] ) {
// phpcs:ignore WordPress.Security.EscapeOutput.OutputNotEscaped
echo $html;
} else {
return $html;
}
}
