 $poddata = Array(
'pod_id' => $this->pod_id,
'url' => $this->url,
'name' => $this->name,
'description' => $this->description,
'service' => $this->service,
'status' =>$this->status,
'price' => $this->price
);

foreach ( $poddata as $k => $v ){

if ( get_post_meta( $this->id, $k ) == '' )
add_post_meta( $this->id, $meta_box, $v, true );

elseif ( $v != get_post_meta( $this->id, $k, true ) )
update_post_meta( $this->id, $k, $v );

elseif ( $v == '' )
delete_post_meta( $this->id, $k, get_post_meta( $this->id, $k, true ) );

}

I have an array saved in postmata, each array key become a metakey. I want to change the code to save the whole array with one metakey. How to do that? Thanks!

$poddata = Array(
'pod_id' => $this->pod_id,
'url' => $this->url,
'name' => $this->name,
'description' => $this->description,
'service' => $this->service,
'status' =>$this->status,
'price' => $this->price
);

foreach ( $poddata as $k => $v ){

if ( get_post_meta( $this->id, $k ) == '' )
add_post_meta( $this->id, $meta_box, $v, true );

elseif ( $v != get_post_meta( $this->id, $k, true ) )
update_post_meta( $this->id, $k, $v );

elseif ( $v == '' )
delete_post_meta( $this->id, $k, get_post_meta( $this->id, $k, true ) );

}

Vousn'avezpasbesoin deparcourir les valeurs.Utilisez simplement update_post_meta($post_ID, {key}, {array of vals}),ça devraitfaire!

 <?php
$poddata = Array(
    'pod_id' => $this->pod_id,
    'url' => $this->url,
    'name' => $this->name,
    'description' => $this->description,
    'service' => $this->service,
    'status' =>$this->status,
    'price' => $this->price
    );

//Update inserts a new entry if it doesn't exist, updates otherwise
update_post_meta($post_ID, 'poddata', $poddata);
?>

C'esttout!Lorsque vous le récupérezpour utilisation,procédez comme suit:

     $poddata = get_post_meta($post_ID, 'poddata');

$poddataest letableau de valeurs.

You don't need to loop through the values. Just use update_post_meta($post_ID, {key}, {array of vals}), it should do!

<?php
$poddata = Array(
    'pod_id' => $this->pod_id,
    'url' => $this->url,
    'name' => $this->name,
    'description' => $this->description,
    'service' => $this->service,
    'status' =>$this->status,
    'price' => $this->price
    );

//Update inserts a new entry if it doesn't exist, updates otherwise
update_post_meta($post_ID, 'poddata', $poddata);
?>

Thats it! When you fetch it for usage, do the following:

    $poddata = get_post_meta($post_ID, 'poddata');

$poddata is the array of values.

J'aiessayé update_post_meta ($post_ID,'poddata',$postdata),après avoirenregistré lemessage,je vois que lamétan'estpasenregistrée.

I tried update_post_meta($post_ID, 'poddata', $postdata), after save the post, i see the meta is not saved.

Lors de la récupération des données,parget_post_meta ($post ID,'posdata'); J'obtiens array (0) de var_dump.Commentpuis-je obtenir letableau complet?

When retrive the data, by get_post_meta($post_ID, 'poddata'); I get array(0) from var_dump. How can I get the whole array?

De rien! Essayez d'utiliserprint_r () ... echo "
"; print_r ($poddata); echo "
";
You're welcome! Try using print_r()... echo "
"; print_r($poddata); echo "
";

print_r ($poddata) affiche Array ()

print_r($poddata) shows Array()

Ohh ... alors les valeursne sontpas stockées.Vous obtenez untableau vide.J'aiessayé l'exemple localementet cela abien fonctionné.Essayez unprint_r dutableau de valeurs avant demettre àjour_post_meta.Iln'obtientprobablement aucune valeur.

Ohh... then the values aren't stored. You're getting an empty array. I tried the example locally, and it worked fine. Try a print_r of the array of values before you update_post_meta. It's probably not getting any values.

It's stored, I can see it in phpAdmin, new posts has metakey of "pod" and and value of the array. Just can't fetch it.

Essayez `$poddata=get_post_meta ($post_ID,'poddata',true);`

Try `$poddata = get_post_meta($post_ID, 'poddata',true);`

Jenny,essayez aussi la solution ci-dessus. @Bainternet J'ai délibérémentignoré letroisièmeparamètre,quiest le drapeau «unique»,car la valeurmétaest untableau dansget_post_meta.Est-cenécessairepourtraiter destableaux au lieu de chaînes commeméta-valeurs?Jene l'utilise que lorsqueje stocke des chaînesen tant queméta-valeurs.

Jenny, Try the above solution too. @Bainternet I deliberately skipped the third parameter, which is the 'single' flag, as the meta value is an array in get_post_meta. Is it required when dealing with arrays instead of strings as meta values? I use it only when I store strings as meta values.

Le vrai 3èmeparamètre doit êtreignoré si vous avezplus d'un champs avec lemêmenom,sa valeurpeut être une chaîne,unbooléen,unentier ou untableaumais cen'estpas de quoiil s'agit.

The true 3rd parameter should be skipped if you have more then one fields with the same name, it value can be a string,boolean,integer or array but that is not what this parameter is about.

Thanks! Now I've a clear understanding of the 'true' parameter!
