Laravel : How to send variable from one page to another in blade - php

Question

I'm building a laravel application where from The first page I want to send a variable or say value to second page in a form ..How do I do it?
Let's say In my first page I have several buttons so when a user click on any one button, he will be redirected to another page where he has to submit a form.
In first page while he select a button, he automatically select a course_id which will also submit inside the second page form. But How do i send the course_id from the first page button?
<li> A </li>
<li> <a href="{{route('registration')}}" >B</a> </li>
When a user click on the button second page will appear ..Where I'm gonna submit a form where course_id will come from the first page means the <a> tag
Here is my form demo:
{!! Form::open(array('route' => 'postRegistration','class'=>'form-horizontal','method'=>'POST')) !!}
{!! Form::token(); !!}
{!! csrf_field() ; !!}
<div class="form-group">
<label class="sr-only" for="form-first-name">Name</label>
<input type="text" name="name" placeholder="Name..." class="form-first-name form-control" id="form-first-name">
</div>
<div class="form-group">
<label class="sr-only" for="form-email">Email</label>
<input type="text" name="email" placeholder="Email..." class="form-email form-control" id="form-email">
</div>
<div class="form-group">
<label class="sr-only" for="form-last-name">Address</label>
<textarea rows="4" style="height:100px;" name="address" placeholder="Address..." class="form-last-name form-control" id="form-last-name"></textarea>
</div>
<button type="submit" class="btn">Submit</button>
{!! Form::close() !!}
In my database I have to submit the above field as well as the course_id from the database.
How do I do it in Laravel?
Any suggestion or solution please?

Answer 1

You can send the variable as route parameter. To do this change your <a> tags like this.
<li> A </li>
<li> B </li>
Then you need to allow your registration route to take parameter. Suppose your route is like this
Route::get('/registration', [
'as' => 'registration', 'uses' => 'SomeController#method'
]);
Change it to
Route::get('/registration/{course_id}', [
'as' => 'registration', 'uses' => 'SomeController#method'
]);
Now you have to add this parameter into your SomeController#method
public method($course_id){ ... }
Now pass this $course_id to your form view. To submit this variable with your other fields you can add this as hidden input field.
<div class="form-group">
<input type="hidden" name="course_id" value="{{ $course_id }}">
</div>

Answer 2

So you want to create page with multiple course links and each link redirects to registration page with the course id to be used in the registration form.
Your a href link should look like this
{!! link_to_route('registration',
$title = 'Course 1', $parameters = ['1'], $attributes =
['class'=>'btn btn-success']) !!}
Routes file web.php
Route::get('/registration/{course_id}','
CourseRegistration#showForm')->name('registration');
CourseController CourseController
public function showForm($course_id){
return view('registration')->with('courseid',$course_id);
}
Now you can access the course id with $courseid in view. If you want to pass it in form create a hidden or input tag with the data.

Answer 3

According to me, you're looking for a type of web app in which when a user submits a form the page opens up with the registered user details.
This can be done in Laravel like this:
routes.php
// For submitting form on this route
Route::post('users/register', 'UsersController#create')->name('users.register');
// For showing user's profile via user's id
Route::get('users/{id}/profile', 'UsersController#show')->name('users.profile');
UsersController.php
class UsersController {
public function create() {
$inputs = request()->all();
// Use Eloquent to save user info to DB and fetch insert id from DB...
return redirect()->route('users.profile', array('id' => $insert_id));
// Will open registered user profile page
}
public function show($id) {
$user = User::find($id);
if(!$user) {
abort('404');
}
return view('users/profile', compact('user'));
// At the users/profile.php page you can use $user variable to populate user's info
}
}
Usage of route method with passing data with route in Blade
{{ route('users.profile', array('id' => $user->id)) }}
