php - Making data save in uppercase with laravel

Solution:

You can use validation hopefully it will solve your problem

public function store(Request $request)
{
    $validator = Validator::make($request->all(), [
    '//your_field' => 'required|string|regex:/(^([A-Z]))/u'   
     ]);
        if ($validator->fails()){
            return "invalid data";
        }
else{
    $energy = new Energy;
    $energy->energyid = $request->input('energyid');
    $energy->energydetail = $request->input('energydetail');
    $energy->save();
    return redirect('/page')->with('success', 'data added');
}

}
Copy code

Solution:

There are a couple of ways with which you can achieve this, one is as mentioned by Doggo$energy->energyid = strtoupper($request->input('energyid')); and the other is creating a request file and using a package (https://github.com/Waavi/Sanitizer)

here is how your code will look like

class EnergyStoreRequest extends BaseFormRequest
{
    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    {
        return true;
    }

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    {
        return [
            'energyid' => 'required',
            'energydetail' => 'required'
        ];
    }


    /**
     *  Filters to be applied to the input.
     *
     * @return array
     */
    public function filters()
    {
        return [
            'energyid' => 'trim|uppercase',
        ];
    }

}
Copy code

And your controller will look likt this

public function store(EnergyStoreRequest $request)
    {
      $input = $request->validated();
      $energy = new Energy;
      $energy->energyid = $input['energyid'];
      $energy->energydetail = $input['energydetail'];
      $energy->save();
      return redirect('/page')->with('success', 'data added');
    }
Copy code
