How to send the information from an HTML form to a CrudController?

  • 772

I want to save the information from an formHTML, in the database, through my CrudController.

But I have not known how to do it, my variables formare called the same as in my database and everything.

This is my file blade.

<form method="POST" action="/save_design">
    <input type="text" name="name" placeholder="Nombre del diseño">
    <input type="submit" value="Guardar">
</form>

And I get a little confused about the routes, I don't know if I should consult in web.phpor in custom.php. What I did in web.phpwas the following:

<?php

Route::post('/save_design', 'DesignController@setupCreateOperation');

But I have errors, likeApp\Http\Controllers\Admin\DesignCrudController is not invokable.

    In order to store the information that comes from your form I propose the following changes:

    First in your error message I notice that you have this folder structure:

    Controllers
 ----Admin
     ----DesignController

    To achieve the above you must execute from the terminal:

    php artisan make:controller Admin/DesignController

    Once that is done you will have the folder path mentioned above

    Changing the path in your fileweb.php

    Code:

    Route::get('/save_design/create', 'Admin\DesignController@create')->name('save_design.create');
Route::post('/save_design', 'Admin\DesignController@store')->name('save_design.store');

    What I did:

    • I call the name of the controller file preceded by the name of the folder Adminin this case that contains it and a backslash\
    • Add a name to the route through the method name(), this same name will be used to invoke it in the actionform
    • The file web.phpstores your routes but is not the one you should call
    • Inside you you controllermust have at least these 2 methods: createand store, where createit shows the form and storeprocesses the data to store it

    • I recommend editing the name of your method in the controller from: setupCreateOperation to store not only to improve its handling by having a simpler name but also to identify what operation we are doing

      • create: What is used to show the registration form through the methodGET

      • store: That will receive the data from the form with the help of the object $requestthat helps us process the data of the requests by some HTTP verb and in this case it will bePOST

    Modifying the code of your form

    <form method="POST" action="{{ route('save_design.store') }}">
    @csrf
    <input type="text" name="name" placeholder="Nombre del diseño">
    <input type="submit" value="Guardar">
</form>

    What I did was:

    • In it I call the name that I gave to the route that will process the registration of my record actionthrough the helperroute
    • Should I make use of the blade directive@csrf

    Now in the controller

    It should look something like this:

    <?php

namespace App\Http\Controllers\Admin;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;


use App\Modelo;

class DesignController extends BaseController
{
    public function create()
    {
        return view('vistaFormulario');
    }

    public function store(Request $request)
    {
      $registroNuevo = new Modelo;
      $registroNuevo->name = $request->input('name');
      ....
      ....
      $registroNuevo->save();
    }
}

    What I did was:

    • I invoke by its namespace the model that will help me to save the record in the corresponding table, there you must place the respective name that your
    • I create a new instance of said model assigning it to an object inside the methodstore
    • With the new object $nuevoRegistroI access ->the desired column by means of its name nameand later I obtain the value that I received from the form with the help of the object$request
    • I read the value that arrives from inputthrough its name attribute, which in this case isname
    • Finally, to register my new line, I use the methodsave
