Ваш ответ отлично работает в первом массиве lvl, например:
$args['meta_query'][] = array(
'key' => 'tour_itinerario_ciudades_repeater_%_tour_ciudades_nombre',
'_key_compare' => 'LIKE',
'value' => 'MEXICO',
'compare' => 'LIKE',
);
Мне нужно сделать некоторые изменения для работы во втором уровне в массиве:
$args['meta_query'][] = array(
'relation' => 'OR',
array(
'key' => 'tour_itinerario_ciudades_repeater_%_tour_ciudades_nombre',
'_key_compare' => 'LIKE',
'value' => 'CONDESA',
'compare' => 'LIKE',
),
array(
'key' => 'tour_itinerario_ciudades_repeater_%_tour_ciudades_nombre',
'_key_compare' => 'LIKE',
'value' => 'Ciudad 1',
'compare' => 'LIKE',
)
);
Теперь,
add_action('pre_get_posts', function( $q ) {
// Check the meta query:
$mq = $q->get('meta_query');
if (empty($mq))
return;
// Init:
$marker = '___tmp_marker___';
$rx = [];
// Collect all the sub meta queries, that use REGEXP, RLIKE or LIKE:
// Only works for 1st level in array
foreach ($mq as $k => $m) {
if (isset($m['_key_compare']) && in_array(strtoupper($m['_key_compare']), [ 'REGEXP', 'RLIKE', 'LIKE']) && isset($m['key'])
) {
// Mark the key with a unique string to secure the later replacements:
$m['key'] .= $marker . $k; // Make the appended tmp marker unique
// Modify the corresponding original query variable:
$q->query_vars['meta_query'][$k]['key'] = $m['key'];
// Collect it:
$rx[$k] = $m;
}
}
// custom code to make it work with arguments on Multidimensional array
foreach ($mq as $k => $m) {
foreach ($m as $k_i => $m_i) {
if (count($m_i) >= 3) {
if (isset($m_i['_key_compare']) && in_array(strtoupper($m_i['_key_compare']), [ 'REGEXP', 'RLIKE', 'LIKE']) && isset($m_i['key'])
) {
// Mark the key with a unique string to secure the later replacements:
$m_i['key'] .= $marker . $k_i; // Make the appended tmp marker unique
// Modify the corresponding original query variable:
$q->query_vars['meta_query'][$k][$k_i]['key'] = $m_i['key'];
// Collect it:
$rx[$k][$k_i] = $m_i;
}
}
}
}
// Nothing to do:
if (empty($rx))
return;
// Get access the generated SQL of the meta query:
add_filter('get_meta_sql', function( $sql ) use ( $rx, $marker ) {
// Only run once:
static $nr = 0;
if (0 != $nr++)
return $sql;
// Modify WHERE part where we replace the temporary markers:
//PRIMER NIVEL
foreach ($rx as $k => $r) {
$sql['where'] = str_replace(
sprintf(
".meta_key = '%s' ", $r['key']
), sprintf(
".meta_key %s '%s' ", $r['_key_compare'], str_replace(
$marker . $k, '', $r['key']
)
), $sql['where']
);
}
//SECOND NIVEL
foreach ($rx as $k => $r) {
//TODO: test with several cases since may have bugs
if (!isset($r['key'])) {//FORZO LA ENTRADA
foreach ($r as $k_i => $r_i) {
$sql['where'] = str_replace(
sprintf(
".meta_key = '%s' ", $r_i['key']
), sprintf(
".meta_key %s '%s' ", $r_i['_key_compare'], str_replace(
$marker . $k_i, '', $r_i['key']
)
), $sql['where']
);
}
}
}
var_dump($sql);
return $sql;
});
}); Просто, если любой нужен аналогичный ответ,
