我试图在特定的自定义字段中提供一个包含所有值的数组。值本身也是数组。我尝试了各种数组函数,但没有遇到正确的一个或正确的组合。到目前为止,这是我的代码:
$args = array(
'post_type' => 'match_report',
'post_status' => 'publish',
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'report_home-scorers'
),
array(
'key' => 'report_away-scorers'
)
)
);
$reportscore = new WP_Query($args);
$scorersResults = array();
if ( $reportscore->have_posts() ) {
while ( $reportscore->have_posts() ) {
$reportscore->the_post();
$homescorers = get_post_meta($post->ID,'report_home-scorers',false);
$awayscorers = get_post_meta($post->ID,'report_away-scorers',false);
foreach ($homescorers as $homescorer){
array_push($scorersResults, $homescorer);
}
foreach ($awayscorers as $awayscorer){
array_push($scorersResults, $awayscorer);
}
?>
<?php } wp_reset_postdata(); //endif
}//endwhile
$scorerResults = remove_empty($scorersResults);
function remove_empty($array) {
return array_filter($array, '_remove_empty_internal');
}
function _remove_empty_internal($value) {
return !empty($value) || $value === 0;
}
如果我这样做,我会得到什么print_r($scorerResults);
:
Array
(
[1] => Array
(
[0] => 1
[1] => 63
)
[2] => Array
(
[0] => 263
[1] => 195
)
[3] => Array
(
[0] =>
)
[4] => Array
(
[0] =>
)
)
我只想要数组中内部数组中的值。
