如果我从这里添加代码https://stackoverflow.com/a/31904911/21533506它只会在产品标题中搜索：
function search_by_title( $search, $wp_query ) {
if ( ! empty( $search ) && ! empty( $wp_query->query_vars['search_terms'] ) ) {
global $wpdb;
$q = $wp_query->query_vars;
$n = ! empty( $q['exact'] ) ? '' : '%';
$search = array();
foreach ( ( array ) $q['search_terms'] as $term )
$search[] = $wpdb->prepare( "$wpdb->posts.post_title LIKE %s", $n . $wpdb->esc_like( $term ) . $n );
if ( ! is_user_logged_in() )
$search[] = "$wpdb->posts.post_password = ''";
$search = ' AND ' . implode( ' AND ', $search );
}
return $search;
}
$args = array(
's' => 'search string',
'numberposts' => 5,
'offset' => 0,
'category' => 0,
'orderby' => 'post_date',
'order' => 'DESC',
'post_type' => 'post',
'post_status' => 'publish',
'suppress_filters' => true);
add_filter( 'posts_search', 'search_by_title', 10, 2 );
$recent_posts = wp_get_recent_posts($args, ARRAY_A);
remove_filter( 'posts_search', 'search_by_title', 500 );
foreach($recent_posts as $posts) {
// your custom code here
}
如果我从这里添加代码https://wordpress.stackexchange.com/a/412121按SKU搜索：
function search_by_sku( $search, $query_vars ) {
global $wpdb;
if(isset($query_vars->query['s']) && !empty($query_vars->query['s'])){
$args = array(
'posts_per_page' => -1,
'post_type' => 'product',
'meta_query' => array(
array(
'key' => '_sku',
'value' => $query_vars->query['s'],
'compare' => 'LIKE'
)
)
);
$posts = get_posts($args);
if(empty($posts)) return $search;
$get_post_ids = array();
foreach($posts as $post){
$get_post_ids[] = $post->ID;
}
if(sizeof( $get_post_ids ) > 0 ) {
$search = str_replace( 'AND (((', "AND ((({$wpdb->posts}.ID IN (" . implode( ',', $get_post_ids ) . ")) OR (", $search);
}
}
return $search;
}
add_filter( 'posts_search', 'search_by_sku', 999, 2 );
如果我添加两者，它只会从产品标题中搜索。我尝试将它们组合起来，但我没有设法使它们发挥作用。你能帮我一下吗？
原文：
根据此处的代码https://awhitepixel.com/making-autocomplete-search-in-wordpress-with-code/，我有以下代码：
add_action('wp_enqueue_scripts', function() {
wp_enqueue_script('autocomplete-search', get_stylesheet_directory_uri() . '/assets/js/autocomplete.js',
['jquery', 'jquery-ui-autocomplete'], null, true);
wp_localize_script('autocomplete-search', 'AutocompleteSearch', [
'ajax_url' => admin_url('admin-ajax.php'),
'ajax_nonce' => wp_create_nonce('autocompleteSearchNonce')
]);
$wp_scripts = wp_scripts();
wp_enqueue_style('jquery-ui-css',
'//ajax.googleapis.com/ajax/libs/jqueryui/' . $wp_scripts->registered['jquery-ui-autocomplete']->ver . '/themes/smoothness/jquery-ui.css',
false, null, false
);
});
add_action('wp_ajax_nopriv_autocompleteSearch', 'awp_autocomplete_search');
add_action('wp_ajax_autocompleteSearch', 'awp_autocomplete_search');
function awp_autocomplete_search() {
check_ajax_referer('autocompleteSearchNonce', 'security');
$search_term = sanitize_text_field($_REQUEST['term']);
if (!isset($search_term)) {
echo json_encode([]);
wp_die();
}
$suggestions = [];
// Query for products
$args = [
'post_type' => 'product',
'posts_per_page' => -1,
's' => $search_term,
];
$query = new WP_Query($args);
if ($query->have_posts()) {
while ($query->have_posts()) {
$query->the_post();
global $product;
$product_id = $product->get_id();
$product_name = $product->get_name();
$product_image_url = get_the_post_thumbnail_url($product_id, 'thumbnail'); // Obține URL-ul imaginii produsului
$suggestions[] = [
'id' => $product_id,
'label' => $product_name,
'image' => $product_image_url, // Adaugă URL-ul imaginii produsului în array
'link' => get_permalink($product_id),
];
}
wp_reset_postdata();
}
echo json_encode($suggestions);
wp_die();
}
add_action('wp_head','woocommerce_js');
function woocommerce_js() {
// break out of php ?>
<script>
jQuery(function($) {
$('.woocommerce-product-search input[type="search"]').autocomplete({
source: function(request, response) {
$.ajax({
dataType: 'json',
url: AutocompleteSearch.ajax_url,
data: {
term: request.term,
action: 'autocompleteSearch',
security: AutocompleteSearch.ajax_nonce,
},
success: function(data) {
response(data);
}
});
},
select: function(event, ui) {
window.location.href = ui.item.link;
},
}).data('ui-autocomplete')._renderItem = function(ul, item) {
return $('<li>')
.append('<div><img src="' + item.image + '" width="25" height="25" style="float:left; margin-right:10px;">' + item.label + '</div>')
.appendTo(ul);
};
});
</script>
<?php
}
它工作正常，但是...我怎样才能让它只在产品标题和SKU中搜索？可以帮我修改一下吗？
我的代码也是在产品描述中搜索，而不是按SKU搜索。我尝试修改它，但无法使其发挥作用。你能帮我解决问题吗？
提前谢谢您！
你可以修改你的awp_autocomplete_search方法来实现
function awp_autocomplete_search() {
check_ajax_referer('autocompleteSearchNonce', 'security');
$search_term = sanitize_text_field($_REQUEST['term']);
if (!isset($search_term)) {
echo json_encode([]);
wp_die();
}
$suggestions = [];
// Custom WHERE clause to search in post_title and meta_value (for SKU)
add_filter('posts_where', 'custom_posts_where', 10, 2);
function custom_posts_where($where, $query) {
global $wpdb;
$search_term = $query->query_vars['s'];
if (!empty($search_term)) {
$where .= $wpdb->prepare(" OR {$wpdb->postmeta}.meta_key = '_sku' AND {$wpdb->postmeta}.meta_value LIKE %s", '%' . $wpdb->esc_like($search_term) . '%');
}
return $where;
}
$args = [
'post_type' => 'product',
'posts_per_page' => -1,
's' => $search_term,
'meta_query' => [
'relation' => 'OR',
[
'key' => '_sku',
'value' => $search_term,
'compare' => 'LIKE',
],
],
];
$query = new WP_Query($args);
remove_filter('posts_where', 'custom_posts_where', 10);
if ($query->have_posts()) {
while ($query->have_posts()) {
$query->the_post();
global $product;
$product_id = $product->get_id();
$product_name = $product->get_name();
$product_image_url = get_the_post_thumbnail_url($product_id, 'thumbnail');
$suggestions[] = [
'id' => $product_id,
'label' => $product_name,
'image' => $product_image_url,
'link' => get_permalink($product_id),
];
}
wp_reset_postdata();
}
echo json_encode($suggestions);
wp_die();
}
