This is my full coding,
<?php
if(isset($_POST['submit']))
{
$username = $_POST['username'];
$password = $_POST['password'];
if($username && $password){
$insert = mysql_query("INSERT INTO users VALUES('', '$username', '$password')");
$msg = "User is created successfully";
}
else{
$error = "Please fillup all required fields!";
}
}
?>
<form class="form-horizontal" action="settings_user.php" method="POST">
<div class="form-group"><label class="col-lg-2 control-label">User Name</label>
<div class="col-lg-4"><input type="text" name="username" placeholder="" class="form-control" autofocus>
</div>
</div>
<div class="form-group"><label class="col-lg-2 control-label">Password</label>
<div class="col-lg-4"><input type="password" name="password" placeholder="" class="form-control"></div>
</div>
<div class="form-group">
<div class="col-lg-offset-2 col-lg-10">
<button class="btn btn-sm btn-primary" name="submit" type="submit">ADD</button>
</div>
</div>
<?php echo $msg; ?>
<?php echo $error; ?>
</form>
two error message appears: Undefined index for $msg and $error
how can I fix this?
This might work. Instead of using 2 variables for "success" and "failure", use single variable and put the message accordingly. Initialize the variable globally.
<?php
$msg="";
if(isset($_POST['submit'])) {
$username = $_POST['username']; $password = $_POST['password'];
if($username && $password){
$insert = mysql_query("INSERT INTO users VALUES('', '$username', '$password')");
$msg = "User is created successfully";
}
else{
$msg = "Please fillup all required fields!";
}
}
?>

I have the following form:
<form asp-controller="Manage" asp-action="RemoveDetails" method="post" class="form-horizontal">
#if (Model.RequirePassword)
{
<div id="password-container">
<div class="col-md-6">
<div class="form-group">
<label asp-for="Password"></label>
<input asp-for="Password" class="form-control" id="password" autocomplete="current-password" aria-required="true" />
<small>
<span asp-validation-for="Password" class="text-danger"></span>
</small>
</div>
</div>
</div>
}
<div class="col-6">
<hr class="mt-2 mb-3">
<button type="submit" class="btn btn-style-1 btn-danger">Confirm</button>
</div>
<div class="row">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
</div>
</form>
If I leave the password empty, a validation message (the model uses DataAnnonations) is displayed right below the control. This is fine.
If I enter the wrong password, the Post action validates it and adds an error to the ModelState. This error is displayed below the form.
Is it possible to display such model errors below the relevant controls?
Try this code in Controller: ModelState.AddModelError("Password", "validation summary error."); The error message won't display in <div asp-validation-summary="ModelOnly"></div>, but it can display error message in #Html.ValidationSummary(false, "", new { #class = "text-danger" }).

I'm new to laravel 8. I try to make an update function controller when user already edit their data and store it in database. I try to click submit button and it's not working without any reason when i try to inspect at chrome. So i try another way which is comment the $request->validate and it's only change for name data while organisation_id leave blank and return to NULL. I wonder do we need to always validate the data in update function ?
Here is my Controller
public function edit($id)
{
$record = User::find($id);
$org = Organisation::all();
$t = Organisation::pluck("name");
return view ('user.edit',compact('record','org','t'));
}
public function edit_store(Request $request, $id)
{
$request->validate([
'name' => 'required',
'organisation_id' => 'required',
]
);
$record= User::find($id);
$record->name = $request->name;
$record->organisation_id = $request->organisation_id;
$record->save();
return redirect ('user')->with('success', 'Thank you');
}
Here is my edit blade
<div class="card">
<div class="card-body">
<form action="{{route('user_edit_store1', $record->id)}}" method="POST">
#csrf
<input type="hidden" name="id" value="{{ $record->id }}">
<div class="form-group row">
<label for="name"
class="col-md-4 col-form-label text-md-right">{{ __('Name') }}</label>
<div class="col-md-6">
<input id="name" type="text"
class="form-control #error('name') is-invalid #enderror" name="name"
value="{{ old('name') ? old('name') : $record->name }}"
</div>
</div>
<div class="form-group row">
<label for="organisation_id"
class="col-md-4 col-form-label text-md-right">{{ __('Organisation') }}</label>
<div class="col-md-6">
{!! Form::open(['route' => 'user_store']) !!}
{!! Form::select('id', $t, 'id', ['class' => 'form-control']) !!}
</div>
</div>
<div class="form-group row mb-0">
<div class="col-md-6 offset-md-4">
<button type="submit" class="btn btn-primary" >
{{ __('Save') }}
</button>
</div>
</div>
</form>
</div>
</div>
Routes
Route::get('user_edit/{id}',[UserController::class,'edit'])->name('user_edit');
Route::post('user_edit_store/{user}',[UserController::class,'edit_store'])->name('user_edit_store1');
Model user.php
protected $fillable = [
'name',
'organisation_id',
];
It appears that the <select> that you're creating with the Form::select form helper will have name of 'id' instead of 'organisation_id' which will result in a validation fail.

When I debug, IFormFile is always null. I tried using [FromForm] but it didn't help. I googled and found out that my name in form and parameter name was different but it had effect. Could you, please give me a little hint on how I can solve it. Thank you and have a good day!
You have to specify <form>'s enctype attribute set to multipart/form-data to be able to send files to server
<form class="form" method="post" asp-controller="Meal" asp-action="Update" enctype="multipart/form-data">
