Php Solutions
Solution 1 - Php
You can use the following:
return Redirect::back()->withInput(Input::all());
If you're using Form Request Validation, this is exactly how Laravel will redirect you back with errors and the given input.
Excerpt from \Illuminate\Foundation\Validation\ValidatesRequests:
> return redirect()->to($this->getRedirectUrl()) > ->withInput($request->input()) > ->withErrors($errors, $this->errorBag());
Solution 2 - Php
write old function on your fields value for example
<input type="text" name="username" value="{{ old('username') }}">
Solution 3 - Php
In your HTML you have to use value = {{ old('') }}. Without using it, you can't get the value back because what session will store in their cache.
Like for a name validation, this will be-
<input type="text" name="name" value="{{ old('name') }}" />
Now, you can get the value after submitting it if there is error with redirect.
return redirect()->back()->withInput();
As @infomaniac says, you can also use the Input class directly,
return Redirect::back()->withInput(Input::all());
Add:
If you only show the specific field, then use $request->only()
return redirect()->back()->withInput($request->only('name'));

Solution 4 - Php
this will work definately !!!
$validation = Validator::make($request->all(),[
'name' => ['Required','alpha']
]);
if($validation->passes()){
print_r($request->name);
}
else{
//this will return the errors & to check put "dd($errors);" in your blade(view)
return back()->withErrors($validation)->withInput();
}
Solution 5 - Php
You can use any of these two:
return redirect()->back()->withInput(Input::all())->with('message', 'Some message');
Or,
return redirect('url_goes_here')->withInput(Input::all())->with('message', 'Some message');
Solution 6 - Php
I handle validation exceptions in Laravel 5.3 like this. If you use Laravel Collective it will automatically display errors next to inputs and if you use laracasts/flash it will also show first validation error as a notice.
Handler.php render:
public function render($request, Exception $e)
{
if ($e instanceof \Illuminate\Validation\ValidationException) {
return $this->handleValidationException($request, $e);
}
(..)
}
And the function:
protected function handleValidationException($request, $e)
{
$errors = @$e->validator->errors()->toArray();
$message = null;
if (count($errors)) {
$firstKey = array_keys($errors)[0];
$message = @$e->validator->errors()->get($firstKey)[0];
if (strlen($message) == 0) {
$message = "An error has occurred when trying to register";
}
}
if ($message == null) {
$message = "An unknown error has occured";
}
\Flash::error($message);
return \Illuminate\Support\Facades\Redirect::back()->withErrors($e->validator)->withInput();
}
Solution 7 - Php
Laravel 5:
return redirect(...)->withInput();
for back only:
return back()->withInput();
Solution 8 - Php
You can try this:
return redirect()->back()->withInput(Input::all())->with('message', 'Something
went wrong!');
Solution 9 - Php
For Laravel 5
return redirect()->back()->withInput();
For Laravel 6, 7 and 8
return back()->withInput();

Solution 10 - Php
$request->flash('request',$request);
<input type="text" class="form-control" name="name" value="{{ old('name') }}">
It works for me.
