Filtrer certaines valeurs d'un tableau dans un post_meta sérialisé (PHP)

Question

J'ai installé dans Wordpress un type de message personnalisé (artistes) ...

J'ai un plugin qui serializez les méta-informations des artistes .. et j'ai besoin de filtrer ces informations par le canal ..: « canal »; s: 6: « transe » qui est aussi dans la méta sérialisé « show_data »

'a:1:{s:32:"57fba1b113187b95554339a0737e0309";a:7:{s:7:"dj_name";s:7:"DjValue";s:9:"show_name";s:9:"ShowValue";s:7:"channel";s:6:"trance";s:10:"show_image";s:0:"";s:4:"time";s:1:"0";s:8:"time_end";s:1:"0";s:4:"mon1";s:1:"1";}}' 

le plugin unserializez les données comme ceci:

foreach ($djs as $dj) { 
     $temp = maybe_unserialize(get_post_meta($dj->ID, 'show_data', true)); 
     if ($temp) 
      $show_data[ ] = maybe_unserialize(get_post_meta($dj->ID, 'show_data', true)); 

} //$djs as $dj 

Puis passe à la boucle à travers les tableaux .... pour former un calendrier ....

je dois filtrer par type de canal (trance ou techno) ... j'ai essayé avec array_filter mais .. eu pas de chance :(.. im pretty vert en php

j'aurais besoin de quelque chose comme ceci:

[78] => Array (
    [57fba1b113187b95554339a0737e0309] => Array (
     [dj_name] => DjValue 
     [show_name] => ShowValue 
     [channel] => trance 
     [show_image] => 
     ) 
    ) 
[79] => Array (
    [55ebc09f567af40917f650f430339772] => Array (
     [dj_name] => Emilian 
     [show_name] => Emilians Trance 
     [channel] => techno 
     [show_image] => 
     ) 
    ) 

puis filtrer uniquement la transe en utilisant les arguments de shortcode ... résultat devrait être ...

[78] => Array (
    [57fba1b113187b95554339a0737e0309] => Array (
     [dj_name] => DjValue 
     [show_name] => ShowValue 
     [channel] => trance 
     [show_image] => 
     ) 
    ) 

Merci à advanceee

Answer 1

filtre Array est un bon essai, avez-vous fait comme ceci:

$channel = 'trance'; 
$show_data = array_filter($show_data, function($data) use ($channel) { 
    return $data['channel'] == $channel; 
}); 

Answer 2

Vous pouvez le faire en array_filter() en utilisant tout La clé a de la valeur.

Par exempleChannel => trance puis il retournera les tableaux correspondants.

$value = 'trance'; 
$key = 'channel'; 

$show_data = array_filter($array, function($itrate) use ($value,$key) { 
    return $itrate[$key] == $value; 
});
