Question

我有一个名为course_duration的自定义字段，即numeric。

这就是我建立meta_query的方式：

$duration = $_GET['course_duration'];

$args = array(
        'fields'         => 'ids',
        'post_type'  => 'cp_course', 'numberposts' =>-1,'orderby' => 'ID', 'order' => 'ASC', 's' => $searchterm,
        'meta_query' => 
            array(
                'key' => 'course_duration', 
                'type' =>'numeric',
                'compare' => '=',
                'value' => $duration,               
            ),

    );

    $course = get_posts($args);

$duration成功传递，我可以通过echo对其进行检查，并且$searchterm为空。这是产生的$args：

array (size=7)
  'fields' => string 'ids' (length=3)
  'post_type' => string 'cp_course' (length=9)
  'numberposts' => int -1
  'orderby' => string 'ID' (length=2)
  'order' => string 'ASC' (length=3)
  's' => string '' (length=0)
  'meta_query' => 
    array (size=3)
      'key' => string 'course_duration' (length=15)
      'type' => string 'numeric' (length=7)
      'value' => string '5' (length=1)

但是查询失败。它应该只返回带有duration=5的课程，但返回所有课程。我在做什么错了？

编辑

即使我尝试使用硬编码的$duration也不起作用。像这样：

$duration = $_GET['course_duration'];

$args = array(
        'fields'         => 'ids',
        'post_type'  => 'cp_course', 'numberposts' =>-1,'orderby' => 'ID', 'order' => 'ASC', 's' => $searchterm,
        'meta_query' => 
            array(
                'key' => 'course_duration', 
                'type' =>'numeric',
                'compare' => '=',
                'value' => 15,              //Hardcoded
            ),

    );

    $course = get_posts($args);

Answer 1

请使用以下代码：

$duration = $_GET['course_duration'];

$args = array(
        'fields'         => 'ids',
        'post_type'  => 'cp_course', 'numberposts' =>-1,'orderby' => 'ID', 'order' => 'ASC', 's' => $searchterm,
        'meta_query' => 
             array(
     array(
                'key' => 'course_duration', 
                'type' =>'numeric',
                'value' => intval($duration)               
            )
          ),    
    );

    $course = get_posts($args);

在这里您可以为meta_query设置'compare'=>'='
