将数组添加到数组，并将其与特定键关联

Question

我有一个像这样的数组：

$args = array(
    'post_type' => 'player',
    'posts_per_page' => -1,
);

然后我有了另一个数组，例如：

[stateArray] => Array
    (
        [0] => OR
        [1] => WI
    )

我需要添加到原始$args数组中以特别得到此结果：

$args = array(
    'post_type' => 'player',
    'posts_per_page' => -1,
    'meta_query' => array(
        'compare' => 'AND',
           [0] => array(
               'key'     => 'state',
               'value'   => 'OR',
               'compare' => '=',
           ),
           [1] => array(
                'key'     => 'state',
                'value'   => 'WI',
                'compare' => '=',
                ),
    )
);

尝试此代码：

$stateArray = $_POST['stateArray'];
$state_array_wrapper = array('meta_query' => array());
foreach ($stateArray as $state) {
    $single_state_array = array(
        'key'     => 'town_state',
        'value'   => $state,
        'compare' => '='
    );
    array_push($state_array_wrapper, $single_state_array);
}
$state_array_wrapper = array_values($state_array_wrapper);
array_push($args, $state_array_wrapper);

我得到这个结果：

Array (
[post_type] => player
[posts_per_page] => -1
[0] => Array
    (
        [0] => Array
            (
            )

        [1] => Array
            (
                [key] => town_state
                [value] => OR
                [compare] => =
            )

        [2] => Array
            (
                [key] => town_state
                [value] => WI
                [compare] => =
            )

    )

 )

[不知道为什么我在最终数组中根本看不到'meta_query'，或者即使我确实看到了如何将这两个$single_state_array推入meta_query中也是如此。如何正确地做到这一点？

Answer 1

您需要为$ args提供meta_query的密钥那么您需要推送到该数组

$args['meta_query'] = array('compare'=>'AND');

foreach ($stateArray as $state) {

    $single_state_array = array(
        'key'     => 'town_state',
        'value'   => $state,
        'compare' => '='
    );

    array_push($args['meta_query'], $single_state_array);
    /* short hand in php 7 */
    //$args['meta_query'][] = $single_state_array;
}

Answer 2

这看起来很简单。如果我读错了，请告诉我...

$args['meta_query'] = array('compare'=>'AND');
foreach($stateArray as $val)
  $args['meta_query'][] = array('key'=>'town_state', 'value'=>$val, 'compare'=>'=');

就这些。
