Question

我制作了一个代码来获取特定帖子类型cef_donor的所有元数据

$arg = array(
    'post_type' => 'cef_donor',
);
$posts_array = get_posts($arg);

$metaData = array();
foreach($posts_array as $key => $value){
    $metaData[] = get_post_meta($value->ID,'', true);
}

当我打印$ metaData时，我得到这样的数组

Array
(
    [0] => Array
        (
            [meta_key_one] => Array  (
                    [0] => value one
                )
            [meta_key_two] => Array
                (
                    [0] => value two
                )
            [meta_key_three] => Array
                (
                    [0] => value three
                )
        )
    [1] => Array
        (
            [meta_key_one] => Array  (
                    [0] => another value one
                )
            [meta_key_two] => Array
                (
                    [0] => another value two
                )
            [meta_key_three] => Array
                (
                    [0] => another value three
                )
        )
)

但我只需要一个像这样的数组

Array
(
    [0] => Array
        (
            [meta_key_one] => value one
            [meta_key_two] => value two
            [meta_key_three] => value three
        )
    [1] => Array
        (
            [meta_key_one] => another value one
            [meta_key_two] => another value two
            [meta_key_three] => another value three
        )
)

有没有其他简单的方法来获取帖子类型的所有meta_key及其meta_value。请帮忙

您可以创建一个新的。将旧值循环到新值。考虑这个例子：

$metaData = array( array( 'meta_key_one' => array('value_one'), 'meta_key_two' => array('value_two'), 'meta_key_three' => array('value_three'), ), array( 'meta_key_one' => array('another_value_one'), 'meta_key_two' => array('another_value_two'), 'meta_key_three' => array('another_value_three'), ),);
$new_values = array();
foreach($metaData as $key => $value) {
    foreach($value as $index => $element) {
        $new_values[$key][$index] = $element[0];
    }
}

print_r($new_values);

示例输出：

Array
(
    [0] => Array
        (
            [meta_key_one] => value_one
            [meta_key_two] => value_two
            [meta_key_three] => value_three
        )

    [1] => Array
        (
            [meta_key_one] => another_value_one
            [meta_key_two] => another_value_two
            [meta_key_three] => another_value_three
        )

)
