问题
I set debug mode to true in config->app and deployed it on the server:
'debug' => env('APP_DEBUG', true),
I have following code in Controller to check the mode:
...
$debug = config('app.debug');
var_dump($debug);
$product->save();
Result on local machine:
C:\xampp\htdocs\MK\app\Http\Controllers\ProductController.php:45:boolean true
Result on the server:
bool(false) Whoops, looks like something went wrong.
Why isn't debug mode set on server side?
回答1:
This line in your config file, 'debug' => env('APP_DEBUG', true), may be the cause of your issue.
It is saying; set debug to the value defined in my .env file, and if there is none then use true.
As such it is looking at APP_DEBUG=false in your .env file, even though you have set the second parameter to true.
Try updating the setting in your .env file to true.
回答2:
In your case, just go to your .env file and change "APP_DEBUG=false" to "APP_DEBUG=true"
回答3:
You can also change the setting into your .env file from
APP_ENV=production
APP_DEBUG=false
to
APP_ENV=local
APP_DEBUG=true

First of all the debug mode need to be activated! And the APP_ENV need to be set to local.
Now how to do that! We need to check in multiple places
.env file
APP_ENV=local
APP_DEBUG=true
Make sure they are not set twice! You can Uncomment with # APP_ENV=production (using #).
Too importantly you need to change APP_ENV to local.
And to check, you can run
php artisan env
You get something like:
config/app.php
Next thing to check is config/app.php
Know that the .env is processed by this file! And that file is where the config is managed!
Check that the config line is not removed or commented!
(depending if it's a new install or some already worked on project)
Depending on what version of Laravel you are using! It may be slightly different!
But the point is to make sure that the .env config is loaded or it will default to true!
'debug' => env('APP_DEBUG', true) // second param the default value
In our current project! The setting were as bellow:
'debug' => (function_exists('env')) ? env('APP_DEBUG', true) : true,
it check if env exists! if yes it use it ! If not it will set the default value directly!
My teammate! Didn't notice that! And he got an error! Becaues somebody before us have changed it as bellow (and was commented):
The image is added to illustrate how a mistake can be made! Also for navigation clearance!
Bottom line check it out and make sure it's all right! (if all right then just move to the next section)
Ok all set but not working
Yea to be expected !
Clear views and cache
Importantly you should know that you may need to clear the cache
Run
php artisan view:clear
and
php artisan cache:clear
After that it should work!
If not!
Files permissions
You may have file system permission problems!
