I have setup in Wordpress a custom post type ( Artists )...
I have a plugin that serializez the meta information from the Artists .. and i need to filter this information by channel ..: "channel";s:6:"trance" which is also in the serialized meta "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";}}'
The plugin unserializez the data like this :
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
Then goes on to loop through the arrays .... to form a calendar....
i need to filter out by channel type ( trance or techno ) ... i have tried with array_filter but .. had no luck :( .. im pretty green in php
i would have needed something like this :
[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] =>
)
)
then filter out only the trance using the shortcode arguments... result should be...
[78] => Array (
[57fba1b113187b95554339a0737e0309] => Array (
[dj_name] => DjValue
[show_name] => ShowValue
[channel] => trance
[show_image] =>
)
)
Thanks in advanceee

Array filter was a good try, did you do it like this :
$channel = 'trance';
$show_data = array_filter($show_data, function($data) use ($channel) {
return $data['channel'] == $channel;
});
You can do it by array_filter() using any key has value.
For e.g Channel => trance then it will return matched arrays.
$value = 'trance';
$key = 'channel';
$show_data = array_filter($array, function($itrate) use ($value,$key) {
return $itrate[$key] == $value;
});
