How To Solve Laravel and MySql Error Called SQLSTATE[23000] - php

Question

I want to create a Registration form. So, I have created a RegShortController.php file and after I have created view file called RegShort.blade.php. In RegShortController.php file , I have used a function called insert. But , When I run the Web Site , I got this error -
"SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name'
cannot be null (SQL: insert intoacademic(name,username,pw)
values (, , ))"
So , How to Fix this ??
Here is the RegShort.blade.php file
Unfortunately , I have removed name attributes in username and password when I edit this Thread. Now , I fixed it.
<form action="{{ route('RegShort') }}" method="post" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label>Name : *</label>
<input type="text" class="form-control" name="name">
</div>
<div class="form-group">
<label>Username : *</label>
<input type="text" class="form-control" name="username" required>
</div>
<div class="form-group">
<label>Password : *</label>
<input type="password" class="form-control" name="password">
</div>
<button type="submit" class="btn btn-primary" name="submit">Submit</button>
</form>
Here is the RegShortController.php file
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use DB;
class RegShortController extends Controller
{
public function index()
{
return view('RegShort');
}
function insert(Request $req)
{
$name = $req->input('name');
$username = $req->input('username');
$password = $req->input('password');
$data = array("name"=>$name,'username'=>$username,"pw"=>$password);
DB::table('academic')->insert($data);
}
}
Here is the Route that I have created.
Route::any('/RegShort', 'RegShortController#insert')->name('RegShort');

Answer 1

name field must be non empty, so u should validate data before inserting it (server side validation):
function insert(Request $req)
{
$this->validate($req, [
'name' => 'required'
]);
$name = $req->input('name');
$username = $req->input('username');
$password = $req->input('password');
$data = array("name"=>$name,'username'=>$username,"pw"=>$password);
DB::table('academic')->insert($data);
}
BTW would be nice to validate data by javascript as well before sending data to server (client side validation).
Edit ur HTML, uve missed name attributes for ur inputs:
<form action="{{ route('RegShort') }}" method="post" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label>Name : *</label>
<input type="text" class="form-control" name="name">
</div>
<div class="form-group">
<label>Username : *</label>
<input type="text" class="form-control" name="username" required>
</div>
<div class="form-group">
<label>Password : *</label>
<input type="password" name="password" class="form-control">
</div>
<button type="submit" class="btn btn-primary" name="submit">Submit</button>
</form>
Also change ur routes:
Route::get('/RegShort', 'RegShortController#index')->name('RegShort');
Route::post('/RegShort', 'RegShortController#insert');

Answer 2

It seems that you are unable to get data from the $req object. Be sure to check your data before inserting into the table.

Answer 3

you dont have name attribute for username and password
<div class="form-group">
<label>Name : *</label>
<input type="text" class="form-control" name="name">
</div>
<div class="form-group">
<label>Username : *</label>
<input type="text" name="username" class="form-control" required>
</div>
<div class="form-group">
<label>Password : *</label>
<input type="password" name="password" class="form-control">
</div>

Answer 4

Try to update html:
You are messing: name attribute here
<input type="text" name="username" class="form-control" required>
<input type="password" name="password" class="form-control">
Code:
<form action="{{ route('RegShort') }}" method="post" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label>Name : *</label>
<input type="text" class="form-control" name="name">
</div>
<div class="form-group">
<label>Username : *</label>
<input type="text" name="username" class="form-control" required>
</div>
<div class="form-group">
<label>Password : *</label>
<input type="password" name="password" class="form-control">
</div>
<button type="submit" class="btn btn-primary" name="submit">Submit</button>
</form>
