PHP error when uploading large files

when you implement file upload, you find that small files can be uploaded (less than 8M), but when uploading large files, the following error occurs :

Exception ' yii\web\badrequesthttpexception ' with message ' Unable to verify your data submission. ' In/var/www/html/labweb /vendor/yiisoft/yii2/web/controller.php:110

Stack Trace:

#0/var/www/html/labweb/vendor/yiisoft/yii2/base/controller.php: Yii\web\controller->beforeaction (Object (yii\base\inlineaction))

#1/var/www/html/labweb/vendor/yiisoft/yii2/base/module.php (454): yii\base\controller->runaction (' Upload ', Array)

#2/var/www/html/labweb/vendor/yiisoft/yii2/web/application.php (+): yii\base\module->runaction (' Admin/upload ', Array)

#4/var/www/html/labweb/web/index.php (): Yii\base\application->run ()

#5 {main}

After finding the data and verifying, finally find the method, modify the Upload_max_filesize and post_max_size parameters of the php.ini file. The following is a modification of the php.ini file under a Linux system.

First enter the command:

cd/etc/php5/apache2/ PS: Since I am installing PHP5, this is done according to the version of PHP I have installed.

Continue to enter the command:

sudo vim php.ini

Enter php.ini, press/To search upload_max_filesize

After finding this parameter, press the I key to enter edit mode, modify parameters, consider the maximum file that your site may upload, set, here I set to 1GB.

Similarly, find and modify the Post_max_size parameter, consider the maximum file settings that your site might upload, and then save it.

Finally, reboot Apache to

sudo/etc/init.d/apache2 Restart
