A PHP program code for uploading files without refreshing_PHP tutorial

To achieve non-refresh file upload, we have an imaginary way to use the iframe framework to achieve file upload, and the other is to use ajax to achieve file upload. Both methods can achieve the non-refresh file upload function.

The most original and simple iframe upload example:

The front-end upload page index.html is mainly a form and a js callback function. When uploading files, the method and enctype attributes of the form must be the same as the following code. Then set the target value to the name of the iframe, so that files can be uploaded without refreshing.

The code is as follows

代码如下	复制代码
<script>  <br> function CallbackFunction(str){  <br> alert("上传成功");  <br> }  <br> </script>

Copy code

代码如下	复制代码
set_time_limit(0);  if($_SERVER['REQUEST_METHOD']=='POST') {    move_uploaded_file($_FILES["test_file"]["tmp_name"],    dirname($_SERVER['SCRIPT_FILENAME'])."/UploadTemp/" . $_FILES["test_file"]["name"]);    echo "<script>window.parent.CallbackFunction();</script>";  }  ?>

<script> <br> function CallbackFunction(str){ <br> alert("Upload successful"); <br> } <br> </script>

The background upload processing page uploadfile.php, this code is a simple upload code without error and exception handling. After the upload code is executed, you need to tell the parent page that the upload has been completed. Therefore, the callback function CallbackFunction of the parent page is called in this page. This function can have parameters and the form can be defined by yourself.

The code is as follows

Copy code

set_time_limit(0); if($_SERVER['REQUEST_METHOD']=='POST') { move_uploaded_file($_FILES["test_file"]["tmp_name"], dirname($_SERVER['SCRIPT_FILENAME'])."/UploadTemp/" . $_FILES["test_file"]["name"]); echo "<script>window.parent.CallbackFunction();</script>"; } ?> The above is a simple method to use iframe to upload files without refreshing.
