如何通过在运行"wp_insert_post"之前检查帖子标题是否存在来防止重复发帖？

Question

我有一个连接到肥皂服务器的wordpress网站.问题是我每次运行脚本时"wp_insert_post"再次使用相同的结果.我想检查现有的post_title是否与$ title的值匹配,如果匹配,则阻止wp_insert_post再次使用相同的值.

这是代码:

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);

感谢您的任何帮助.

Answer 1

您现在可以使用,get_page_by_title()因为它支持自定义帖子类型.

if (!get_page_by_title($title, OBJECT, 'skarabeepublication')) :

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

endif;

很惊讶没有post_exists在wp-includes/post.php中看到功能的提及.请参阅wpseek上的条目.在手抄本中没有条目.最简单的方法就是get_page_by_title返回一个post id(如果没有找到则返回0)而不是对象(或null).

$post_id = post_exists( $my_title );
if (!$post_id) {
    // code here
}

回复晚了非常抱歉。我使用了机器人在评论中所说的内容，这解决了我的问题。谢谢

$post_if = $wpdb->get_var("SELECT count(post_title) FROM $wpdb->posts WHERE post_title like '$title_from_soap'");
if($post_if < 1){
    //code here
}
