I encountered such trouble recently. The error code returned was 6 when the temporary folder could not be found.

The main method is to find the PHP configuration file php.ini and make corresponding modifications. Please refer to this article for the specific solution. I hope it can help you.

Error reason:

1. The configuration file does not set a temporary folder

2. Temporary folder There is no or the upper-level folder does not have the corresponding permission

Processing method:

Find the PHP configuration file PHP.ini and find the following code

;upload_tmp_dir =

Change to:

upload_tmp_dir = "C:/Windows/Temp"  //后面的文件夹路径根据您的系统来设置

If the permissions are insufficient, you can change it according to the different operating systems. The system adds corresponding permissions to its files respectively

Other knowledge:

Other knowledge With a value of 0, no errors occurred and the file was uploaded successfully.

The value is 1, and the uploaded file exceeds the limit of the upload_max_filesize option in PHP.ini.

The value is 2, and the size of the uploaded file exceeds the value specified by the MAX_FILE_SIZE option in the HTML form.

The value is 3, and only part of the file is uploaded.
