How to store values from Form in Database using Laravel? - php

Question

This is my code for SubscriptionController:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class SubscribersController extends Controller
{
//
//This method is to process the form
public function postSubmit() {
//we check if it's really an AJAX request
if(Request::ajax()) {
$validation = Validator::make(Input::all(), array(
//email field should be required, should be in an email//format, and should be unique
'email' => 'required|email|unique:subscribers,email'
)
);
if($validation->fails()) {
return $validation->errors()->first();
} else {
$create = Subscribers::create(array(
'email' => Input::get('email')
));
if($create){
return Redirect::to('/')
->with('success','You have been successfully subscribe to us.');
}else{
echo 'We could not save your address to oursystem, please try again later';
}
}
} else {
return Redirect::to('subscribers');
}
}
}
This is my code for Eloquent
class CreateSubscribersTable extends Migration
{
public function up()
{
Schema::table('subscribers', function (Blueprint $table) {
$table->increments('id');
$table->string('email,100)->default('');
$table->timestamps();
});
}.....
In the Route/web :
Route::post('/subscribers', 'SubscribersController');
This is the code for welcome.blade.php
<form action="/subscribers" method="post">
<input type="email" name="email" placeholder="Email Address" required>
<button type="button" class="btn btn-danger">Subscribe</button>
</div>
</form>
The code dont insert in database and dont show any error in the console. I put in the postsubmit function echos if error appears and nothing.
I already search one tutorial and dont find.
I´m a noob in Laravel.

Answer 1

Routes should be Route::post('/subscribers','SubscribersController#postSubmit');
and add csrf_field() to form.
<form action="/subscribers" method="post">
{{csrf_field()}}
<input type="email" name="email" placeholder="Email Address" required>
<button type="button" class="btn btn-danger">Subscribe</button>
</div>
</form>`

Answer 2

In your routes file, your route need to send to an action, not just the controller.
Route::post('/subscribers', 'SubscribersController');
should be this
Route::post('/subscribers', 'SubscribersController#postSubmit');
And add the csrf field to your html form:
<form action="/subscribers" method="post">
{{ csrf_field() }}
<input type="email" name="email" placeholder="Email Address" required>
<button type="button" class="btn btn-danger">Subscribe</button>
</form>

Answer 3

First of all, did you run :
php artisan migrate
Second, as Hollings stated above, your route :
Route::post('/subscribers', 'SubscribersController#postSubmit');
Third, top of your SubscribersController, add :
use Subscribers;
Aside of having CreateSubscribersTable extends Migration, you need to have another model class named Subscribers which extends Model. All class you might need to have :
SubscribersController extends Controller (you have it)
CreateSubscribersTable extends Migration (you have this too)
Subscribers extends Model/Eloquent (Do you have this?)
Sorry, that are all i can figure. Will try to check more to help.
Or if you really dying to figure out where the problem is, try to put echo something maybe "Test", within each of your if else.

1) Your migration content is wrong
public function up()
{
Schema::create('subscribers', function (Blueprint $table) { //** 'create', not 'table'
$table->increments('id');
$table->string('email,100)->default('');
$table->timestamps();
});
}
Delete your db contents and php artisan migrate
2) Your form is
<form action="/subscribers" method="post">
{{ csrf_field() }} //** add token
<input type="email" name="email" placeholder="Email Address" required>
<button type="submit" class="btn btn-danger">Subscribe</button> //** Button type : submit
</div>
</form>
Your route:
Route::post('/subscribers', 'SubscribersController#postSubmit');
Your controller
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Subscribers; //********* change this
class SubscribersController extends Controller
{
//This method is to process the form
public function postSubmit(Request $request) {
$validation = Validator::make($request->all(), [
//email field should be required, should be in an email format, and should be unique
'email' => 'required|email|unique:subscribers,email',
]);
if($validation->fails()) {
return $validation->errors()->first();
}
$create = Subscribers::create(array(
'email' => $request->email,
));
return Redirect::to('/')->with('success','You have been successfully subscribe to us.');
}
}
Add protected $table = 'subscribers'; to your Subscribers Model.
Why are you using if (Request::ajax()) ? You are not submitting form via AJAX.
