I've searched the docs and also various search terms here on stack to no avail. Any help would be greatly appreciated.

myController and storage the file

public function imageSave($filex,$destination){

        $ext=$filex->getClientOriginalExtension();
        $name = $filex->getClientOriginalName();
        $mainFilename =$name.'_'.time().'.'.$ext;
        $filex->move($destination, $mainFilename);

        return $mainFilename;
}

public function store(Request $request)
{

    $this -> validertor( $request , [
        'rip' => 'required' ,
        'rip. *' => 'mimes: jpeg, png, jpg, gif, svg | max: 2048',
        'filep' => 'required' ,
        'filep. *' => 'mimes: jpeg, png, jpg, gif, svg | max: 2048',
        'fishea' => 'required' ,
        'fishea. *' => 'mimes: jpeg, png, jpg, gif, svg | max: 2048'
]);

        $data[] = [
            'filep' => $request->filep->getRealPath(),
            [
                'mime' => $request->filep->getClientMimeType(),
                'as' => $request->filep->getClientOriginalName()
            ],
            'rip' => $request->rip->getRealPath(),
            [
                'mime' => $request->rip->getClientMimeType(),
                'as' => $request->rip->getClientOriginalName()
            ],
            'fishea' => $request->fishea->getRealPath(),
            [
                'mime' => $request->fishea->getClientMimeType(),
                'as' => $request->fishea->getClientOriginalName()
            ],
        ];


    if ($request->hasFile('filep') && $request->hasFile('rip') && $request->hasFile('fishea')) {
        $filep = $this->imageSave($request->filep,'uploads/cin/');
        $rip = $this->imageSave($request->rip,'uploads/rip/');
        $fishea = $this->imageSave($request->fishea,'uploads/anthropo/');

        // Required validation
        $contact = new Contact();

        $contact->name = $request->name;
        $contact->adresse = $request->adresse;
        $contact->ville = $request->ville;
        $contact->num = $request->num;


        $contact->filep = $filep;
        $contact->rip   =  $rip;
        $contact->fishea = $fishea;
     }

    $admin_email = 'contact@admin_email.com';
    Mail::to($admin_email)->send(new SendMailP($data));
    session()->flash('success', 'Thank you! ');
