File Validation with redirect

Hi
I have a problem with my file (image) upload.
The upload itself works fine. However, an error occurs in the validation in connection with the resulting redirect, which I cannot explain to myself.
I use this redirect with all form controllers and so far it has output exactly what it should output. As an example I have attached both examples once.
I have also attached the associated private function for validation.
When I use form_open, everything is displayed as it should be displayed.
When I change to form_open_multipart the error occurs

Sorry for my bad english

When I try this the statusError is shown

PHP Code:

if(!$this->validate($this->validation_edit_profile_image())):
    return redirect()->back()
                     ->with('statusError', lang('system/auth/pages/edit_profile_image.messages.error.edit_profile_image'));
else:
    // image upload itself working fine
endif; 


When I add ->with('validation', $this->validator) the statusError and the validation is not shown

PHP Code:

if(!$this->validate($this->validation_edit_profile_image())):
    return redirect()->back()
                     ->with('statusError', lang('system/auth/pages/edit_profile_image.messages.error.edit_profile_image'))
                     ->with('validation', $this->validator);
else:
    // image upload itself working fine
endif; 


In all other controllers where a form is submitted this is working fine, for example

PHP Code:

if(!$this->validate($this->validation_edit_profile())):
    return redirect()->back()
                     ->with('statusError', lang('system/auth/pages/edit_profile.messages.error.edit_profile'))
                     ->with('validation', $this->validator)
                     ->withInput();
else:
    // profile updater
endif; 


Private Validation Function for the Image Upload

PHP Code:

private function validation_edit_profile_image()
    {
        $rules = [
 'avatar' => [
 'rules'  => 'uploaded[avatar],is_image[avatar]|ext_in[avatar,png,jpeg,jpg,gif]|mime_in[avatar,image/png,image/jpg,image/jpeg,image/gif]|max_size[avatar,2048]|max_dims[avatar,1024,1024]',
 'errors' => [
 'ext_in' => lang('system/auth/validation/clubs.edit_profile_image.profile_image.ext_in'),
 'is_image' => lang('system/auth/validation/clubs.edit_profile_image.profile_image.is_image'),
 'max_dims' => lang('system/auth/validation/clubs.edit_profile_image.profile_image.max_dims'),
 'max_size' => lang('system/auth/validation/clubs.edit_profile_image.profile_image.max_size'),
 'mime_in' => lang('system/auth/validation/clubs.edit_profile_image.profile_image.mime_in'),
 'uploaded' => lang('system/auth/validation/clubs.edit_profile_image.profile_image.uploaded')
 ]
            ]
 ];
 return $rules;
    } 


PHP Code:

private function validation_edit_profile()
    {
        $countries_list = $this->countriesModel->getCountriesValidationList();
        $languages_list = $this->languagesModel->getLanguagesValidationList();
        $nationalities_list = $this->countriesModel->getCountriesValidationList();
        $rules = [
 'country' => [
 'rules'  => 'required|in_list['.$countries_list.']',
 'errors' => [
 'in_list' => lang('system/auth/validation/edit_profile.country.in_list'),
 'required' => lang('system/auth/validation/edit_profile.country.required')
 ]
            ],
 'firstname' => [
 'rules'  => 'required|min_length[3]|max_length[255]',
 'errors' => [
 'max_length' => lang('system/auth/validation/edit_profile.firstname.max_length'),
 'min_length' => lang('system/auth/validation/edit_profile.firstname.min_length'),
 'required' => lang('system/auth/validation/edit_profile.firstname.required')
 ]
            ],
            'language' => [
                'rules'  => 'required|in_list['.$languages_list.']',
                'errors' => [
                    'in_list' => lang('system/auth/validation/edit_profile.language.in_list'),
                    'required' => lang('system/auth/validation/edit_profile.language.required')
                ]
            ],
            'lastname' => [
 'rules'  => 'permit_empty|min_length[3]|max_length[255]',
 'errors' => [
 'max_length' => lang('system/auth/validation/edit_profile.lastname.max_length'),
 'min_length' => lang('system/auth/validation/edit_profile.lastname.min_length')
 ]
 ],
            'location' => [
 'rules'  => 'permit_empty|min_length[3]|max_length[255]',
 'errors' => [
 'max_length' => lang('system/auth/validation/edit_profile.location.max_length'),
 'min_length' => lang('system/auth/validation/edit_profile.location.min_length')
 ]
            ],
            'nationality' => [
                'rules'  => 'required|in_list['.$nationalities_list.']',
                'errors' => [
                    'in_list' => lang('system/auth/validation/edit_profile.nationality.in_list'),
                    'required' => lang('system/auth/validation/edit_profile.nationality.required')
                ]
            ]
 ];
 return $rules;
    } 


When I add ->with('validation', $this->validator) the statusError and the validation is not shown

PHP Code:

if(!$this->validate($this->validation_edit_profile_image())):
    return redirect()->back()
                     ->with('statusError', lang('system/auth/pages/edit_profile_image.messages.error.edit_profile_image'))
                     ->with('validation', $this->validator);
else:
    // image upload itself working fine
endif; 


The problem is when you return redirect()->back()->with('validation', $this->validator) second parameter should be string or an array.
In you code you're setting as a parameter validation class object.
Your code should be like

PHP Code:

redirect()->back()->with('validation', $this->validator->getErrors()) 


It sets validation errors as flash data in session.

Good morning

I tried your code but i got still errors

This is my view code, I want to display the errors per each form field
This is working in EVERY other Controller/View Combination as posted below
Only the file upload will not work like this

PHP Code:

<?= form_label(lang('system/auth/pages/edit_profile_image.form.label.profile_image'), 'profile_image', ['class' => 'form-label']); ?>
<?= form_upload('avatar', set_value('avatar', $user->profile_image), ['autocomplete' => 'off', 'class' => 'form-control'.$viewData['bs_form_control_size'].((session()->has('validation') && session('validation')->hasError('avatar'))?' is-invalid':'').((session()->has('validation') && !session('validation')->hasError('avatar'))?' is-valid':''), 'id' => 'profile_image']); ?>
<?= (session()->has('validation') && session('validation')->getError('avatar'))?'<div class="form-text text-danger fw-bold">'.session('validation')->getError('avatar').'</div>':''; ?>

Why can i give class to session in other controllers and here its not workin?
