Remove post if exist by title

时间:2021-05-22 作者:JonatanPN

我想按标题从PHP中删除一篇文章。

如果帖子按标题存在,我有一个发布或更新的代码,但我不知道如何插入wp_delete_post() function.

这是我发布或更新帖子的实际代码(如果帖子按标题存在):

<?php
// require wp-load.php to use built-in WordPress functions
require_once("/var/www/mysite.com/wp-load.php");

//Title
    $TítleProduct = ("Title Product 1");
//Desc
    $Desc = ("Product descripction 1");

// Register Post Data

$post = array();
$post[\'post_status\']   = \'publish\';
$post[\'post_type\']     = \'post\'; // can be a CPT too
$post[\'post_title\']    = "$TítleProduct";
$post[\'post_content\']  = ($Desc);
$post[\'post_author\']   = 1;

    function wp_exist_post_by_title($title)
    {
        global $wpdb;
        $return_id = $wpdb->get_row("SELECT ID FROM wp_posts WHERE post_title = \'" . $title . "\' && post_type = \'post\' ", \'ARRAY_N\');
        if (empty($return_id)) {
            return false;
        } else {
            return $return_id;
        }
    }

    $id = wp_exist_post_by_title($post[\'post_title\']);

    if($id !== false)
    {
        $post[\'ID\'] = $id["0"];
        $post_id = wp_update_post( $post );
    } else {
        $post[\'post_date\']     = $my_post[\'post_date\'];
        $post_id = wp_insert_post( $post );
    }

/*******************************************************
** SIMPLE ERROR CHECKING
*******************************************************/

$finaltext = \'\';

if($post_id){

$finaltext .= \'Se ha creado/actualizado correctamente el post \'.$post[\'ID\'].\'.<br>\';

} else{

$finaltext .= \'Something went wrong and I didn\\\'t insert a new post.<br>\';

}

echo $finaltext;
?>
我试着替换wp_update_post 对于wp_delete_post 并结合wp_delete_post function 但我不知道如何将其结合起来,下面是wp\\u delete\\u post函数代码示例:

function wp_delete_post( $postid = 0, $force_delete = false ) {
    global $wpdb;
 
    $post = $wpdb->get_row( $wpdb->prepare( "SELECT * FROM $wpdb->posts WHERE ID = %d", $postid ) );
 
    if ( ! $post ) {
        return $post;
    }
 
    $post = get_post( $post );
 
    if ( ! $force_delete && ( \'post\' === $post->post_type || \'page\' === $post->post_type ) && \'trash\' !== get_post_status( $postid ) && EMPTY_TRASH_DAYS ) {
        return wp_trash_post( $postid );
    }
 
    if ( \'attachment\' === $post->post_type ) {
        return wp_delete_attachment( $postid, $force_delete );
    }
 
    /**
     * Filters whether a post deletion should take place.
     *
     * @since 4.4.0
     *
     * @param bool|null $delete       Whether to go forward with deletion.
     * @param WP_Post   $post         Post object.
     * @param bool      $force_delete Whether to bypass the Trash.
     */
    $check = apply_filters( \'pre_delete_post\', null, $post, $force_delete );
    if ( null !== $check ) {
        return $check;
    }
 
    /**

    do_action( \'before_delete_post\', $postid, $post );

        if ( $children ) {
            $wpdb->update( $wpdb->posts, $parent_data, $parent_where + array( \'post_type\' => $post->post_type ) );
        }
    }
 
    // Do raw query. wp_get_post_revisions() is filtered.

这个s posts表的title和content列中的WP Query搜索帖子的参数。您可以使用它来缩短代码。下面是一个帮助您入门的示例。

你可以把它钩住wp_footer 只运行一次(保持在那里很糟糕,但对测试很好),或者创建一个cron作业以在选定的时间间隔自动运行它。

function wpse388545_delete_selected_posts() {
    
    $get_posts = get_posts(array(
        \'post_type\' => array(\'post\'),
        \'posts_per_page\' => -1,
        \'s\' => \'This is the search term\',
    ));
    
    if ( !empty($get_posts) ) {
        foreach( $get_posts as $post ) {
            wp_delete_post($post->ID, true);
        }
    }
}
