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 Web server used (IIS, Apache, etc.).
    See the documentation about the Web server used for more details.
    For example, with the IIS server, in the Web server configuration, "Filtering requests" section, click "Modify the function parameters..." and modify the "Maximum allowed content length (bytes)" section.
    Another method to access this setting is to go via the "configuration editor" of IIS, section "system.webServer/security/requestFiltering" sect ion, "requestLimits" and "maxAllowedContentLength" choices..
  • 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 24 applications, select the following key: HKEY_LOCAL_MACHINE\SOFTWARE\PC SOFT\WEBDEV\24.0 on a 32-bit computer and HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\PC SOFT\WEBDEV\24.0 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.
