Eu tenho um site wordpress que se conecta a um servidor de sabão. O problema é que sempre que executo o script, o "wp_insert_post" está usando o mesmo resultado novamente. Gostaria de verificar se o post_title existente corresponde ao valor de $ title e, se corresponderem, evite que o wp_insert_post use o mesmo valor novamente.

Aqui está o código:

try {
    $client = new SoapClient($wsdl, array('login' => $username, 'password' => $password));
    } catch(Exception $e) {
      die('Couldn\'t establish connection to weblink service.');
    }
$publications = $client->GetPublicationSummaries();
foreach ($publications->GetPublicationSummariesResult->PublicationSummaries->PublicationSummary as $publication_summary) {

    // get the complete publication from the webservice
    $publication = $client->getPublication(array,('PublicationId' => $publication_summary->ID))->GetPublicationResult->Publication;

    // get all properties and put them in an array
    $properties = array();
    foreach ($publication->Property as $attribute => $value) {
        $properties[$attribute] = $value;
    }

    // Assemble basic title from properties
    $title = $properties['Address']->Street . ' ' . $properties['Address']->HouseNumber . $properties['Address']->HouseNumberExtension . ', ' . $properties['Address']->City->_;
}

$my_post = array(
    'post_title'=>$title,
    'post_content'=>'my contents',
    'post_status'=>'draft',
    'post_type'=>'skarabeepublication',
    'post_author'=>1,
);
wp_insert_post($my_post);

Obrigado por qualquer ajuda
