Understanding File Upload Limits

File uploads in CloudOnex Business Suite are subject to several PHP configuration limits that may need to be adjusted depending on your needs:

• upload_max_filesize: Maximum size of individual uploaded files
• post_max_size: Maximum size of POST data (should be larger than upload_max_filesize)
• memory_limit: Maximum memory a script can consume
• max_execution_time: Maximum time in seconds a script can run

Adjusting Limits in cPanel & Shared Hosting

If your hosting uses cPanel, you can easily modify PHP settings:

1. Log in to your cPanel account
2. Navigate to Software → Select PHP Version or MultiPHP INI Editor
3. Select your domain if prompted
4. Look for the following directives and adjust their values:

   upload_max_filesize = 64M
   post_max_size = 64M
   memory_limit = 256M
   max_execution_time = 300
   

5. Click Apply Changes or Save

For VPS or Cloud Server: Modifying PHP.ini Settings

If you have direct access to your server's PHP configuration:

1. Locate your php.ini file (common locations):

   • Linux: /etc/php.ini or /etc/php/[version]/apache2/php.ini
   • Windows: C:\php\php.ini

2. Add or modify these lines:

   ; Increase file upload size limit to 64MB
   upload_max_filesize = 64M
   
   ; Increase POST size limit to 64MB (should be equal or larger than upload_max_filesize)
   post_max_size = 64M
   
   ; Increase memory limit to 256MB
   memory_limit = 256M
   
   ; Increase max execution time to 5 minutes
   max_execution_time = 300
   

3. Save the file and restart your web server:

   # Apache on Linux
   sudo service apache2 restart
   
   # Nginx on Linux
   sudo service nginx restart
   
   # XAMPP on Windows
   restart Apache from XAMPP Control Panel
   

Using .htaccess Method

If you don't have access to php.ini or cPanel, you can try using .htaccess:

1. Create or edit .htaccess in your website's root directory
2. Add these lines:

   php_value upload_max_filesize 64M
   php_value post_max_size 64M
   php_value memory_limit 256M
   php_value max_execution_time 300
   

Using ini_set() Method

In some cases, you might need to set these values programmatically:

ini_set('upload_max_filesize', '64M');
ini_set('post_max_size', '64M');
ini_set('memory_limit', '256M');
ini_set('max_execution_time', 300);

Note: Some settings cannot be changed using ini_set() and must be set in php.ini or through server configuration.

Verifying Changes

To verify your changes have taken effect:

1. Create a PHP info file:

   <?php phpinfo(); ?>
   

2. Upload it to your server as info.php
3. Access it through your browser
4. Search for the directives you modified
5. Important: Delete this file after verification for security reasons

Common Issues and Solutions

1. Changes Not Taking Effect:

   • Ensure you're editing the correct php.ini file
   • Restart your web server after changes
   • Check if your hosting provider allows these changes

2. Server Restrictions:

   • Some hosting providers may have hard limits
   • Contact your hosting provider for assistance
   • Consider upgrading your hosting plan if needed

3. Memory Errors During Upload:

   • Increase both memory_limit and max_execution_time
   • Consider optimizing file sizes before upload
   • Implement chunked file uploads for very large files
