SYSTEM FILE IS not generated if i install with composer installation command What is an alternate Option for it brother

[@foxbille]

Very interesting ! Thank you, this helps a lot !
but what if a new version of CI4 is coming ? every thing will be lost.
Like we used to do in CI3 for models, isn't it possible to put the new custom filter in a file located in app/ directory and named MY_Filters ... so that it can "survive" to further CI upgrades ?

[@GoPHP]

Yes, we can keep our filters into a separate folder, it is possible
1.create folder with name Viewfilters or MY_Filters in App folder: \App\Viewfilters
2. create class with name Filters and save it in Viewfilters folder. find the code below
namespace App\Viewfilters;
class Filters {
public static function hideNumbers(string $value, int $display = 4): string
{
$txt = '';
for($i = 0; $i < strlen($value); $i++)
{
if($i < $display)
{
$txt .= $value[$i];
}
else
{
$txt .= "X";
}
}
return $txt;
}
}
3. open view.php from the location App\Config\View.php and find the array
public $filters = [ ]
please update the path of your filter here like:
public $filters = [
'hidenumbers' => '\App\Viewfilters\Filters::hideNumbers',
'someother' => '\CodeIgniter\View\Filters::countVowels',
];
4. in view file apply your filter
Mobile: {mobile|hidenumbers(4)}
Save all the work and please check
I will prepare a small video for this and I'm going to update here
Thank You Eric

works like magic..

[@softwareEngineerKunwar]

thank you for your video.

[@vijaysrini27]

When how do you pass more than two variables in a filter. E.g you showed how to display 6 digits. But suppose, we want to display 6 digits and the remaining with a '*' instead of an 'X' (which should be our choice dynamically), how do we do that?

[@GoPHP]

Vijay, I have checked the manual and other resources as well, as of now I found, we can pass one parameter only, like: hidenumbers(2).
if I found any, I'll update you Vijay

HI Gophp,
When I'm trying to pass variable as 6 in hidenumbers it is showing complete mobile number, it is not hiding last 6 numbers
public function hideNumber(string $value, int $display = 4): string
{
$txt = '';
for($i = 0; $i

Sir System Folder is not in my folder structurer in ci4 how can i setup that?. Simply can we Copy and past sytem folder from the Original Downloaded folder.
is it correct way

[@GoPHP]

how did you install? Manual or Composer
if you did composer installation, no need to download system folder. it will available in C:\xampp\htdocs\Project\vendor\codeigniter4\framework
if you did manual installation, System folder will download automatically
please check...
