如何在使用自定义模板时在wordpress文件夹中保存图像

Question

这是我的代码

 $actual_name = pathinfo($filename,PATHINFO_FILENAME);
   $original_name = $actual_name;
   $extension = pathinfo($filename, PATHINFO_EXTENSION);

  

$文件类型= $ _ FILES [ '文件'] [ '类型'];          $目标= “../可湿性粉剂内容/主题/ childtheme / IMG /”;

   if($filetype=='image/jpeg' or $filetype=='image/png' or 
   $filetype=='image/gif')
   {
   $i = 1;
   while(file_exists($target.$actual_name.".".$extension)){       
   $actual_name = $original_name.$i;
   $filename = $actual_name.".".$extension;
   $i++;
   }
   $target = $target.basename( $filename ) ; 
   move_uploaded_file($_FILES['file']['tmp_name'],$target);
   $insert="INSERT INTO EnterSchool(SliderImg ) VALUES('".$target."' )";

   if (mysqli_query($db, $insert)) {
   echo "saved ";
   }
   else {
   echo "Error: " . $insert . "" . mysqli_error($db);
   }
   $db->close();
   }}
