Question

目前我正在尝试在数组中赋值，这是我现有的数组看起来像..

Array
(
    [detals] => Array
        (
            [0] => Array
                (
                    [make] => xyx
                    [yeardeta] => 2001
                    [model] => Array
                        (
                            [0] => Test one
                            [1] => test fix
                            [2] => Hamour
                            [3] => Imagica
                        )
                )

            [2] => Array
                (
                    [make] => xyx
                    [yeardeta] => 2002
                    [model] => Array
                        (
                            [0] => Test Two
                        )

                )


        )

)

我希望它像这样输出..

<?php
$data = array();
 $cat = get_terms('car_category');
        foreach ($cat as $catVal) {
                   $term_id =$catVal->term_id;

                    $get_query = $wpdb->get_results("SELECT DISTINCT meta_value FROM wp_postmeta as pm
                         LEFT JOIN wp_term_relationships as tr
                         ON tr.object_id=pm.post_id
                         WHERE pm.meta_key='car_year'
                         AND tr.term_taxonomy_id='".$term_id."'");

                foreach ($get_query as $key => $value) {

                    $data[] = array('make'=>$catVal->term_id,'yeardeta'=>$value->meta_value);

                         $get_query = $wpdb->get_results("SELECT post_title FROM wp_posts as p
                                LEFT JOIN wp_postmeta as pm
                                ON p.id=pm.post_id
                                LEFT JOIN wp_term_relationships as tr
                                ON tr.object_id=pm.post_id
                                WHERE pm.meta_key='car_year'
                                AND pm.meta_value='".$value->meta_value."'
                                AND tr.term_taxonomy_id='".$term_id."'");
                         $str = array();
                         foreach ($get_query as $key => $value) {
                              $str[] = $value->post_title;
                        }

                        $data[] = array('model'=>$str);

                }

                $term_id =$catVal->term_id;

                $main_array = array('detals'=>$data);

            print_r($main_array);

        }

?>

这是我的完整PHP代码

我想输出我上面已解释过我该怎么做？

我已修改了粘贴在下面的代码。在循环中，您使用了$data[]两次，因此插入了新的数组元素。请检查以下代码（我无法测试），根据需要进行修改，并告知我任何说明：

<?php
$data = array();
$cat = get_terms('car_category');
foreach ($cat as $catVal) {
    $term_id =$catVal->term_id;

    $get_query = $wpdb->get_results("SELECT DISTINCT meta_value FROM wp_postmeta as pm
         LEFT JOIN wp_term_relationships as tr
         ON tr.object_id=pm.post_id
         WHERE pm.meta_key='car_year'
         AND tr.term_taxonomy_id='".$term_id."'");

    foreach ($get_query as $key => $value) {
        $make = $catVal->term_id;
        $yeardata = $value->meta_value;                    

        $get_query_model = $wpdb->get_results("SELECT post_title FROM wp_posts as p
                LEFT JOIN wp_postmeta as pm
                ON p.id=pm.post_id
                LEFT JOIN wp_term_relationships as tr
                ON tr.object_id=pm.post_id
                WHERE pm.meta_key='car_year'
                AND pm.meta_value='".$value->meta_value."'
                AND tr.term_taxonomy_id='".$term_id."'");
        $model = array();
        foreach ($get_query_model as $model_key => $model_value) {
          $model[] = $model_value->post_title;
        }

        $data[] = array('make'=>$make,'yeardata'=>$yeardata, 'model'=>$model);
    }

    $term_id =$catVal->term_id;

    $main_array = array('detals'=>$data);

    print_r($main_array);

}
?>

Answer 2

而不是

\\file\

替换为

$data[] = array('model'=>$str);

上面的内容在$data['model'] = $str;中创建了一个新数组。

追加 - ＆gt;使用$data['newkey']中的model键。

如何在主数组中安排具有适当值的数组
