上传文件到数据库PHP/WordPress

上传文件到数据库PHP/WordPress

问题描述:

我已经创建了这个PHP代码上传文件到我的数据库(phpMyAdmin),但我不知道如何使它在WordPress上工作。上传文件到数据库PHP/WordPress

$con = mysqli_connect("localhost","root","","mydb"); 
if (mysqli_connect_errno()) { 
    echo "Unable to connect to MySQL! ". mysqli_connect_error(); 
} 
if (isset($_POST['submit'])) { 
    $target_dir = get_template_directory_uri() .'/Uploaded_Files'; 
    $target_file = $target_dir . date("dmYhis") . basename($_FILES["file"]["name"]); 
    $uploadOk = 1; 
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 

    if($imageFileType != "jpg" || $imageFileType != "png" || $imageFileType != "jpeg" || $imageFileType != "gif") { 
     if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) { 
      $files = date("dmYhis") . basename($_FILES["file"]["name"]); 
     } else { 
      echo "Error Uploading File"; 
      exit; 
     } 
    } else { 
     echo "File Not Supported"; 
     exit; 
    } 
    $filename = $_POST['filename']; 
    $location = get_template_directory_uri() .'/Uploaded_Files . $files'; 
    $getuser = $_SESSION['id']; 
    $settime = date("Y-m-d H:i:s"); 
    $setmsg = $con->real_escape_string($_POST['msg']); 
    // Database Query goes here. 
}

_注意:_ phpMyAdmin是不是一个数据库,它是一个基于Web的管理MySQL数据库的工具。 –

哦!我不是指PHPmyadmin作为数据库。无论如何。 – devsam247

通常当我们导出数据库从在WordPress站点它显示了这样的代码,它提供了有关WordPress插件页面等等等等表的信息

-- Table structure for table `wp_commentmeta` 
-- 

CREATE TABLE IF NOT EXISTS `wp_commentmeta` (
    `meta_id` bigint(20) unsigned NOT NULL, 
    `comment_id` bigint(20) unsigned NOT NULL DEFAULT '0', 
    `meta_key` varchar(255) COLLATE utf8mb4_unicode_ci DEFAULT NULL, 
    `meta_value` longtext COLLATE utf8mb4_unicode_ci 
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci; 


AT the head of exported sql sheet it shows...

首先,当工作与WordPress数据库不使用连接,如mysqli_connect,因为WordPress有自己的API与MySQL进行交互,官方文档:https://codex.wordpress.org/Class_Reference/wpdb

您约“WordPress数据库上传文件”说,我想你的意思是将其添加到媒体库的方式,在这种情况下,本教程应该帮助https://rudrastyh.com/wordpress/how-to-add-images-to-media-library-from-uploaded-files-programmatically.html
