php - PHP搜索页面超过1页
问题描述
我在搜索后的 url 链接页面分页上有问题...如果我按升序搜索，结果只会显示在第 1 页，然后如果我单击第 2 页，结果将返回默认列表。我知道问题是由于 url 链接问题引起的，但是任何人都可以给我一个关于如何解决问题的建议..
代码如下
<?php
if(!function_exists("add_action")) {
return;
}
get_header();
the_post();
$member_categories = get_terms(
[
"taxonomy" => "member_category",
"hide_empty" => false
]
);
/** Define default values */
$default_query = [
"post_type" => "directory_member",
"posts_per_page" => 36,
"orderby" => "title",
"order" => "asc",
"keywords" => "",
"paged" => get_query_var("paged")
];
$query = wp_parse_args($_GET, $default_query);
if(isset($_GET["keywords"])) {
$query["s"] = esc_attr($_GET["keywords"]);
}
if(isset($_GET["member_categories"])) {
$query["tax_query"] = [
[
"taxonomy" => "member_category",
"fields" => "term_id",
"terms" => $_GET["member_categories"]
]
];
}
if(isset($_GET["order_by"])) {
$query["orderby"] = esc_attr($_GET["order_by"]);
}
if(isset($_GET["order_by"])) {
$query["order"] = esc_attr($_GET["order"]);
}
$members = new WP_Query($query);

解决方案
问题出在 build_query() 函数内部。不幸的是，您没有提供该功能的来源。我只能猜测您的 build_query() 没有传递所有需要的参数或以错误的方式传递它们。
