Question

现在尝试了几个小时，几乎快要达到临界点了。尝试了很多不同的东西，但似乎无法让我的自定义搜索栏按预定的选择价格范围来查询结果。我正在使用“高级自定义字段”将元标记“ investmentprice”添加到名为“ investments”的自定义帖子类型中。我觉得这与WordPress没有在我的meta_query中选择正确的“键”有关，即使我现在已经做了很多次更改。

以下是配置栏的代码：

vscode.window.createTreeView()

这是我的高级搜索查询功能：

<div class="config_bar cf">
<form method="get" role="search" action="<?php echo esc_url( home_url( '/' ) ); ?>">
    <input type="hidden" name="s" value="">
    <input type="hidden" name="post_type" value="investments" />

    <div class="col">
        <?php 
            $taxonomy = 'type';
            $args = array( 'orderby' => 'name', 
                'order'             => 'ASC',
                'hide_empty'        => true,
            );      
            $tax_terms = get_terms($taxonomy, $args);
        ?>
        <span class="label_inner">Investment Type</span>
        <select name="type" id="type" class="postform standard">
            <option value="" selected="selected">All Investment Types </option>
            <?php if($tax_terms): ?>
                <?php foreach ($tax_terms as $tax_term): ?>
                    <?php $title = $tax_term->name;

除非有任何其他问题，否则这应该是一个小问题。您在元查询中使用数组键“ terms”而不是“ value”。根据{{3}}，元查询的嵌套args数组应使用 value ，如下所示：
