我有一个自定义搜索代码,用于搜索WooCommerce订阅的元字段。它有效,但是有一个因某种原因而没有搜索的元?我想知道是否可能是因为其数字?
function custom_search_query( $query ) {
$custom_fields = array(
// put all the meta fields you want to search for here
"gender",
"barcode",
"birthdate",
"employment"
);
$searchterm = $query->query_vars['s'];
// we have to remove the "s" parameter from the query, because it will prevent the posts from being found
$query->query_vars['s'] = "";
if ($searchterm != "") {
$meta_query = array('relation' => 'OR');
foreach($custom_fields as $cf) {
array_push($meta_query, array(
'key' => $cf,
'value' => $searchterm,
'compare' => '=='
));
}
$query->set("meta_query", $meta_query);
};
}
add_filter( "pre_get_posts", "custom_search_query");
其他字段(性别,出生日期和就业)都可以完美搜索。但是“条形码”并不是出于某种原因,我对此感到困惑。例如,当我删除“生日”时,它不会搜索我是否在搜索框中输入了生日,因此我知道此代码有效。
任何帮助都会很棒!
