帮助：点击已发布按钮后，将WP与原始PHP代码集成

时间：2020-04-29 作者：XATA

大家好，让我打开，我不擅长两种Wp编码，我想集成我的Wp站点，这样一旦点击发布/更新按钮，它就会自动将外部mp3文件导入到我的服务器，并将外部mp3链接更改为刚刚导入到我的服务器的，但是这已经完成，下面是我使用的代码，尽管它是一个插件。

class DX_Auto_Save_Images{

    function __construct(){     

        //filter and action hook
        add_filter( \'content_save_pre\',array($this,\'post_save_images\') );   //save images
        add_action( \'admin_menu\', array( $this, \'menu_page\' ) );        //menu page
        add_filter( \'intermediate_image_sizes_advanced\', array( $this, \'remove_tmb\' ) );    //remove tmb
        add_action( \'submitpost_box\', array( $this, \'submit_box\' ) );   //submit_box
        add_action( \'submitpage_box\', array( $this, \'submit_box\' ) );   //submit_box
    }



    //save post exterior images
    function post_save_images( $content ){
        if( ($_POST[\'save\'] || $_POST[\'publish\']) && ($_POST[\'DS_switch\']!=\'not_save\') ){
            set_time_limit(240);
            global $post;
            $post_id=$post->ID;
            $preg=preg_match_all(\'/<a.*?href="(.*?)"/\',stripslashes($content),$matches);
            if($preg){
                $i = 1;
                foreach($matches[1] as $image_url){
                    if(empty($image_url)) continue;
                    $pos=strpos($image_url,get_bloginfo(\'url\'));
                    if($pos===false){

                    }
                    $i++;
                }
            }
        }
        remove_filter( \'content_save_pre\', array( $this, \'post_save_images\' ) );
        return $content;
    }

虽然我修改了一个插件来获得这个结果。

现在，我想将这段代码集成到我已经拥有的ID3 php音乐脚本中，这样我就可以更改专辑的艺术，歌曲的标题和艺人的名字将与wp帖子标题上的完全匹配，然后，wp内容中导入的外部url将通过此php脚本，一旦点击发布按钮，它将只在后端工作，并更改wordpress编辑器上的链接。下面是php脚本，无论脚本的php部分如何，如果我在浏览器上运行它，它都可以正常工作，这只是我想要与wp集成以共同工作的脚本的索引。

如果要在发布或编辑帖子时触发某些操作，可以查看save_post 和edit_post 行动。

您可以轻松地挂接编辑过程，在需要时修改帖子数据，然后再次保存。

function myplugin_save_post($post_id, $post) {
  // $post contains the post itself
  // so you can check the submitted data and see if you need to update it
  // $post->post_title is what you are looking for
  // call your script to get the music data
  // save the data in the wp_postmeta table so you can retrieve it later
}
add_action(\'edit_post\', \'myplugin_save_post\', 10, 2);
add_action(\'save_post\', \'myplugin_save_post\', 10, 2);
