Laravel load settings from cache - php

Question

I'm using Laravel 5.7, and I'm saving settings in the database.
public function store(Request $request)
{
$data = $request->only('app_name', 'app_desc', 'company_phone', 'company_address',
'service_wage', 'kavenegar_api', 'kavenegar_number'
);
foreach ($data as $key => $value) {
Setting::updateOrInsert(
['name' => $key],
['val' => $value]
);
}
return redirect()->back()->withFlashSuccess("saved");
}
I can get settings with the following helper.
if (!function_exists('getSetting')) {
function getSetting($key)
{
return Setting::where('name', $key)->value('val');
}
}
But there is a problem; We are listing all settings and calling getSetting('setting_name') multiple times which is making one query to the database for each call. That’s a lot of queries to get the settings.
I want to use the cache but how can I when the settings are stored in the database? I also save them in the cache.

Answer 1

It's pretty straightforward. Consult the docs on caching for details, but the basic idea is this:
function getSetting($key)
{
return Cache::remember('setting:' . $key, 3600, function() use($key) {
return Setting::where('name',$key)->value('val');
});
}
You could also cache all the settings into a single cache value. Depending on how many of the settings there are and what proportion you use in an average request, that may or may not be a good approach.

Answer 2

try this
if (!function_exists('getSetting'))
{
function getSetting($key)
{
return Setting::where('name', $key)->first()->val;
}
}
And Dont forget to add the Namespace App\Setting
How does the function Work
For Example if you have the setting named as app_name and While You pass the value to the function
Setting::where('name', $key)->first()->val;
getSetting('app_name'); it will find the first record with the key app_name and select the val field value from the object and returns it
UPDATED FOR THE CACHE
THIS IS UNTESTED FUNCTION
function getSetting($name)
{
if (Cache::has('setting_'.$name)) {
return Cache::get('setting_'.$name);
}
$query = Setting::where('name', $key)->first();
Cache::forever('setting_'.$name, $query->val);
return $query->val;
}
This Will remember the cache forever and visit the documentation to read about the cache
https://laravel.com/docs/5.8/cache
And dont forget to add the use Illuminate\Support\Facades\Cache; in the namespace list
