would like to extend the loop elements to include an option for enabling front end element such as a drop-down where the user can select how many items are presented per page.
the following code which is called into my template via {do_action:woocommerce_before_shop_loop}
has no effect on my products element loop unfortunately. it does work when used with the default woocmmerce template:
<?php
remove_action( 'woocommerce_before_shop_loop', 'woocommerce_catalog_ordering', 30 );
function woocommerce_catalog_page_ordering() {
?>
<?php echo '<span class="itemsorder">Items Per Page:' ?>
<form action="" method="POST" name="results" class="woocommerce-ordering">
<select name="woocommerce-sort-by-columns" id="woocommerce-sort-by-columns" class="sortby" onchange="this.form.submit()">
<?php
//Get products on page reload
if (isset($_POST['woocommerce-sort-by-columns']) && (($_COOKIE['shop_pageResults'] <> $_POST['woocommerce-sort-by-columns']))) {
$numberOfProductsPerPage = $_POST['woocommerce-sort-by-columns'];
} else {
$numberOfProductsPerPage = $_COOKIE['shop_pageResults'];
}
// This is where you can change the amounts per page that the user will use feel free to change the numbers and text as you want, in my case we had 4 products per row so I chose to have multiples of four for the user to select.
$shopCatalog_orderby = apply_filters('woocommerce_sortby_page', array(
//Add as many of these as you like, -1 shows all products per page
// '' => __('Results per page', 'woocommerce'),
'30' => __('30', 'woocommerce'),
'60' => __('60', 'woocommerce'),
'-1' => __('All', 'woocommerce'),
));
foreach ( $shopCatalog_orderby as $sort_id => $sort_name )
echo '<option value="' . $sort_id . '" ' . selected( $numberOfProductsPerPage, $sort_id, true ) . ' >' . $sort_name . '</option>';
?>
</select>
</form>
<?php echo ' </span>' ?>
<?php
}
// set cookie if needed
function dl_sort_by_page($count) {
if (isset($_COOKIE['shop_pageResults'])) { // if normal page load with cookie
$count = $_COOKIE['shop_pageResults'];
}
if (isset($_POST['woocommerce-sort-by-columns'])) { //if form submitted
setcookie('shop_pageResults', $_POST['woocommerce-sort-by-columns'], time()+1209600, '/', 'www.your-domain-goes-here.com', false); //this will fail if any part of page has been output- hope this works!
$count = $_POST['woocommerce-sort-by-columns'];
}
// else normal page load and no cookie
return $count;
}
add_filter('loop_shop_per_page','dl_sort_by_page');
add_action( 'woocommerce_before_shop_loop', 'woocommerce_catalog_page_ordering', 20 );
