Remarks

Maximum size of files to upload

By default, the size of files to upload is not limited in the WEBDEV engine. This size can be limited by the WEBDEV Application Server.
The file will not be uploaded if its size exceeds the limit size.
To modify the maximum size of files to upload in WEBDEV application server, the registry must be modified on the server:
  1. To modify the size of the uploaded files for all the WEBDEV 28 applications, select the following key: HKEY_LOCAL_MACHINE\SOFTWARE\PC SOFT\WEBDEV\28.0 on a 32-bit computer and HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PC SOFT\WEBDEV\28.0 on a 64-bit computer.
  2. Add the MAX_UPLOAD string. The value of this string will be the maximum size of files to upload (in KB).
PHP Limits in PHP:
  • The size of the uploaded files is limited by the "upload_max_filesize" directive in the configuration file of PHP (php.ini file).
  • The file upload must be allowed by the PHP server. To do so, the "file_uploads" directive must be set to "on" in the configuration file of PHP (php.ini file).
  • The upload_tmp_dir directive of the configuration file must be specified toward a directory with read/write rights.

Pre-launched sessions

If your project uses pre-launched sessions, this function must not be used in the project initialization event. This function must be used in the "Initializing the project after connection to the site" event.
