This is probably a basic question and something fairly easy to many people.
How can I connect for example a switch/radio button to change a value in my config.
For example I need to be able to toggle a maintenance page on and off I found this stackoverflow which basically says use the below code to change the value but I am struggling how to connect a switch radio button or something to it
If you do that, then maintenance mode will be on for just that request. If you want it on permanently (until someone flips the switch again) then that’s a more complex issue.
For the first situation (where you turn on maintenance mode for the current request) you just need to send a request to a controller action either via a form submit or AJAX and on the action side check the current state of the check-box (e.g. is it checked?) if yes [color=#660066][size=2]Yii[/size][/color][color=#666600][size=2]::[/size][/color][size=2]$app[/size][color=#666600][size=2]->[/size][/color][size=2]maintenanceMode[/size][color=#666600][size=2]->[/size][/color][size=2]enable to true, if not checked the set it to false.[/size]
[size=2]For the second situation you need to manipulate the config file and for this you need yii’s advanced application or a similar setup, in which a backend application switches the frontend application into maintenance mode.[/size]
[size=2]To do this, you have to have a form or ajax that send the current state of the check-box to a backed controller action. From there you include the frontend config file into a variable, activate or deactivate maintenance mode and then write using http://php.net/manual/en/function.var-export.php to the config file.[/size]
[size=2]If you don’t have to advanced application, then you have to put a condition to not block admin’s out of the application if it’s in maintenance mode.[/size]
[size=2]There are other tricks also, for example in the main config you can include a script for the maintenance mode value that dynamically return true or false based on cookies or IP etc.[/size]
