laravel pass data from blade file to Controller

Question

I am trying to take data that a user inputs into a form, created in blade, and transport that data to my controller. At that point I can use a function in my controller to write the data into MySQL.

Here is the code for the form which I have in my blade file.

<form action="{{ route("users") }}" method="post">

<input type ="form" id="firstname"> firstname </input> <br>
<input type ="form" id="lastname"> lastname </input> <br>
<input type="form" id="email"> email </input> <br>
<input type="form" id="userlevel"> userlevel </input> <br>
<input type="form" id="password"> password </input> <br>


<br> <br>
<button type="submit"> Submit
</button>
</form>

Here is the code in my controller which writes data into MySQL. The code works when I am using dummy data, instead of the $name and $lastname variables.

public function users()
{
    $name = $_POST["firstname"];
    $lastname = $_POST["lastname"];

    DB :: table("newUsers") -> insertGetId
    (
        array("firstname" => $name, "lastname" => $lastname, "email" => "test")
    );

    return view("pages.users");
}

I am currently getting an error that says

Undefined index: firstname

Ideally what I want to happen is for whatever the user entered for firstname and lastname to be written into my MySQL table.

You need to add name attributes to your inputs and format them correctly they should look more like:

<input type="text" id="firstname" name="firstname"></input>

If you are placing 'firstname' between your openning and closing input tags for a placholder value use the placeholder attribute instead.

<input type="text" id="firstname" name="firstname" placeholder="first name"></input>

But do be warned the placeholder attribute doesnt work in older browsers

Also dont use $_POST laravel has built in ways of getting the values from your form.

Laravel 5

$request->input('firstname');

like this:

public function users(Request $request)
{
    $name = $request->input('firstname'); // This is better than using $_POST
    $lastname = $request->input('lastname');

    DB :: table("newUsers") -> insertGetId
    (
        array("firstname" => $name, "lastname" => $lastname, "email" => "test")
     );

    return view("pages.users");
}

Notice, I have passed in Request $request like a variable in the method users . You will also need to add use Illuminate\\Http\\Request as Request; to the top of your class:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request as Request; //here

class MyController extends Controller
{
}

Laravel 4

Input::get('firstname');

Answer 2

Change your Form as follows:

<form action="{{ route("users") }}" method="post">
  <input type ="form" name=firstname" id="firstname" placeholder="First name"> 
  <input type ="form" name=lastname" id="lastname">
  <input type="form" name="email" id="email">

  <button type="submit"> Submit </button>
</form>

You've to provide the name attribute to your form fields.

And in the controller, you don't have to use $_POST anymore.

Just use:

public function users(Request $request)
{
   $firstname = $request->input('firstname');
   $lastname = $request->input('lastname');

    DB :: table("newUsers") -> insertGetId(
       array("firstname" => $name, "lastname" => $lastname, "email" => "test")
    );
    return view("pages.users");
 }

You can access form data with $request->get('first_name') , for example.

To make it work, add name tags to your form inputs and catch data, for example, if you use store action:

function store(Request $request){

}

In this case you also can easily validate input data by using custom Reuqest classes: https://laravel.com/docs/master/validation#form-request-validation
