检查页面是否存在问题

我创建了一个类来动态创建页面。通过将新页面的标题与post_name. 这个比较似乎很有效，但即使有匹配项，页面也会被创建，我不知道为什么。

我的代码如下所示：

class createDynamicPage {

public function __construct( $nameArray ) {
    $this->title = $nameArray[\'title\']; //Title of the page
    $this->slug = $nameArray[\'slug\']; //Page slug
}

public $pageContent = \'\';

public function rps_createPage(){
    $allPages = get_pages();
    $exists = false;
    foreach( $allPages as $page ){
        if( strtolower( $page->post_name ) == strtolower( $this->title ) ){
            $exists = true;
        }
    }
    if( $exisits == false ) {
        $new_page_id = wp_insert_post(
            array(
                \'post_title\' => $this->title,
                \'post_type\'     => \'page\',
                \'post_name\'  => $this->slug,
                \'comment_status\' => \'closed\',
                \'ping_status\' => \'closed\',
                \'post_content\' => $this->pageContent,
                \'post_status\' => \'publish\',
                \'post_author\' => 1,
                \'menu_order\' => 0
            )
        );
    }
}

}

$cdArray = array( \'title\' => \'Biography\', \'slug\' => \'concert-diary\' );
$pageConcertDiary = new createDynamicPage( $cdArray );
add_action(\'init\', array( &$pageConcertDiary, \'rps_createPage\' ));

我想我很笨，但我想不出来！此外，作为一名OOP新手，我很乐意接受批评/指点，说明我是如何概述课程的。

干杯

$title = \'mytitlee\'; global $wpdb; $id_ofpost_name = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_name = \'$title\'"); $id_ofpost_title = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_title = \'$title\'"); if ($id_ofpost_name || $id_ofpost_title) {echo \'Exists, here is the id:\'.$id_ofpost_title.\' or \'.$id_ofpost_name;} else {echo \'post wasnt found\';}

WP_LINK_PAGES输出出现两次

我认为这与所问的问题完全不同here.我正在使用过滤器挂钩向主题添加分页。输出显示在内容的开头和结尾，而不仅仅是结尾。我的函数，在模板的函数中。php文件：add_filter(\'the_content\',\'pagination_after_post\',1); /** * Adds pagination after the post * * @uses is_single() */ function pagination_after
