Do you know withInput() and Validation errors?

redirect()->withInput() and Validation errors have an undocumented behavior.

If you redirect with withInput():

PHP Code:

if (! $this->validate($rules)) {
    return redirect()->back()->withInput();
} 


https://github.com/kenjis/ci4-validation...hp#L53-L55

You can use the Validation object with the validation errors in the previous page.

PHP Code:

<?= service('Validation')->listErrors() ?>

https://github.com/kenjis/ci4-validation...rm2.php#L7

But this feature has bugs or design flaw.
So I would like to remove the feature, and add a new helper function to get the validation errors.

Any opinion?

@luckmoshy What do you mean?
Have you ever used the feature?

@kenjis of cause at earlier from CI 4.0 I didn't know what to do with redirect withinput back and get a specific error because of  CI documentation The global return

PHP Code:

redirect()->back()->withInput(); 


  was not shown any specific errors result method or how to get a specific error or succeeded reply from failed action query. So when you call this action, I totally agree with you that we should have errors resulting from the helper function than using a 

PHP Code:

<?= service('Validation')->listErrors() ?>

(validation) service in view or  look we see we can get an errors to list ok and how about succeded result ?? or  is it formed for only errors result???!!!

@kenjis  I truly have been using this  global CI

PHP Code:

redirect()->back()->withInput(); 


  with additional fourth session methods like 

PHP Code:

redirect()->back()->withInput()->with('danger/*success*/',/*In modal*/$this->modal->errors() /*or something else apart with modal */); 


and then

PHP Code:

session()->get('danger/*success*/'); / 


in a view

but I may have a view of the point that it could be good if you design a new helper function and may have a specific single error validation result perimeter or with multiple validations on its parameter something like that or  this

PHP Code:

redirect()->back()->withInput(); 


in  additionally, Why this

PHP Code:

redirect()->back()->withInput(); 


if you have an app with a bulk of routes with

Code:

routes priority

it redirects back to an unintended route  so it's forcedly me to use

PHP Code:

redirect()->to(current_url())->withInput();

The undocumented redirect()->withInput() and Validation errors behavior was treated as a bug.
It won't work, so do not use it.

Since v4.3, you can use Form helper validation_list_errors() (and validation_errors(), validation_show_error()).
