Create a Dynamic Modal using PHP and HTMX #0

Imam Ali Mustofa ・ Mar 26

Well, I am still at the point where I left before. Yes! The next part about:

The Head Voice!

How can I create a modal that display form to create a new supplier in my app and load the content from backend (Yes! PHP) that generate the content, also doing validation and stuff, and removing the modal after the create operation is done!.

Jd Headless Jd GIF - https://tenor.com/view/jd-headless-jd-john-dorian-bye-funny-gif-14134807

After I create a the modal and displaying form with awesome CSS transition (copy & paste) from htmx docs. Then what I need is make that form work with insert action.

The Routing #2 POST

To make the form work with backend I need to create 1 more route that handle POST request from client to server.

<?php
// Filename: /home/darkterminal/workspaces/fck-htmx/routes/web.php
use Fckin\core\Application;

/** @var Application $app  */

$app->router->get('suppliers/create', 'Suppliers@create');
$app->router->post('suppliers/create', 'Suppliers@create');
Enter fullscreen mode Exit fullscreen mode

Myself: Why you don't use match routing method? Like:

$app-router->match(['GET','POST'], 'suppliers/create', 'Suppliers@create')
Enter fullscreen mode Exit fullscreen mode

Aaaah... I won't! If you want, create for yourself! (btw, it's not available in my fck PHP Framework, cz I am too egoist). Don't ask about the my fck PHP Framework documentation, they doesn't exists.

The Controller #2 POST

Still in the same file, but need lil tweak! ✨

The controller before

<?php
// Filename: /home/darkterminal/workspaces/fck-htmx/controllers/Suppliers.php

namespace App\controllers;

use App\config\helpers\Utils;
use App\models\Suppliers as ModelsSuppliers;
use Fckin\core\Controller;
use Fckin\core\Request;
use Fckin\core\Response;

class Suppliers extends Controller
{
    protected $suppliers;

    public function __construct()
    {
        $response = new Response();
        if (!isAuthenticate()) {
            $response->setStatusCode(401);
            exit();
        }
        $this->suppliers = new ModelsSuppliers();
    }

public function create(Request $request)
    {
        $params = []; // <-- I will do it something here when make POST request

        return Utils::addComponent('suppliers/modals/modal-create', $params);
    }
}
Enter fullscreen mode Exit fullscreen mode

The controller after

<?php
// Filename: /home/darkterminal/workspaces/fck-htmx/controllers/Suppliers.php

namespace App\controllers;

use App\config\helpers\Utils;
use App\models\Suppliers as ModelsSuppliers;
use Fckin\core\Controller;
use Fckin\core\Request;
use Fckin\core\Response;

class Suppliers extends Controller
{
    protected $suppliers;

    public function __construct()
    {
        $response = new Response();
        if (!isAuthenticate()) {
            $response->setStatusCode(401);
            exit();
        }
        $this->suppliers = new ModelsSuppliers();
    }

    public function create(Request $request)
    {
        $params = [
            'errors' => []
        ];
        if ($request->isPost()) {
            $formData = $request->getBody();
            $formData['supplierCoordinate'] = empty($formData['latitude']) || empty($formData['latitude']) ? null : \implode(',', [$formData['latitude'], $formData['longitude']]);
            $formData = Utils::remove_keys($formData, ['latitude', 'longitude']);
            $this->suppliers->loadData($formData);
            if ($this->suppliers->validate() && $this->suppliers->create($formData)) {
                \header('HX-Trigger: closeModal, loadTableSupplier');
                 exit();
            } else {
                $params['errors'] = $this->suppliers->errors;
            }
        }

        return Utils::addComponent('suppliers/modals/modal-create', $params);
    }
}
Enter fullscreen mode Exit fullscreen mode

Emmm.... deez neat! How the App\models\Suppliers as ModelsSuppliers look like? Did you mean the Model? Sure whatever you want! But before going further... I need to breakdown deez controller first.

$this->suppliers = new ModelsSuppliers();
Enter fullscreen mode Exit fullscreen mode

Initialized the supplier model that accessible in the entire Class Controller from the __constructor method. Then I modify the $params variable

$params = [
    'errors' => []
];
Enter fullscreen mode Exit fullscreen mode

I add the errors key that store the error messages from validation. The validation part I will explain in the next paragraph, so the story will be inline as possible. Trust me!

if ($request->isPost())
Enter fullscreen mode Exit fullscreen mode

Check if the client request to POST method, if yes then collect the payload from that request using

$formData = $request->getBody();
Enter fullscreen mode Exit fullscreen mode

and store into $formData variable. Because I am handsome and stupid I create field for latitude and longitude separately and don't comment about the ternary if else statement! Pleaaaaseee....

$formData['supplierCoordinate'] = empty($formData['latitude']) || empty($formData['latitude']) ? null : \implode(',', [$formData['latitude'], $formData['longitude']]);
Enter fullscreen mode Exit fullscreen mode

So I can combine the latitude and longitude as a supplierCoordinate value. Then remove the latitude and longitude from payload cz I don't need anymore.

$formData = Utils::remove_keys($formData, ['latitude', 'longitude']);
Enter fullscreen mode Exit fullscreen mode

Also I load that payload into the model

$this->suppliers->loadData($formData);
Enter fullscreen mode Exit fullscreen mode

So the model can read all the payload and validate the payload

$this->suppliers->validate()
Enter fullscreen mode Exit fullscreen mode

In the background I have the rules for the input. They look like this:

public function rules(): array
{
    return [
        'supplierName' => [self::RULE_REQUIRED],
        'supplierCompanyName' => [self::RULE_REQUIRED],
        'supplierAddress' => [self::RULE_REQUIRED],
        'supplierPhoneNumber' => [self::RULE_REQUIRED],
        'supplierEmail' => [self::RULE_EMAIL],
        'supplierCoordinate' => []
    ];
}
Enter fullscreen mode Exit fullscreen mode

If validation passed! Then create the new supplier from the payload

$this->suppliers->create($formData)
Enter fullscreen mode Exit fullscreen mode

If both of them is passed then send the trigger event to the client from the backend

\header('HX-Trigger: closeModal, loadTableSupplier');
Enter fullscreen mode Exit fullscreen mode

Wait! Wait!! Wait!!! Please... tell me where what the loadTableSupplier?! Where is the table!

Sorry for that... I will explain. Please be patient...

The HX-Trigger is the way how htmx communicate between server and client. This trigger place into the response headers. then telling the client to react on that event.

and if one of them (the validate and create) method doesn't passed then

$params['errors'] = $this->suppliers->errors;
Enter fullscreen mode Exit fullscreen mode

get the error messages to the response payload.

return Utils::addComponent('suppliers/modals/modal-create', $params);
Enter fullscreen mode Exit fullscreen mode

the Utils::addComponent is a glue and part of hypermedia content that can deliver to the client instead sending fixed-format JSON Data APIs.

Error Validation Message

Did you remember the Utils::getValidationError method in my form?

Utils::getValidationError($errors, 'supplierName')
Enter fullscreen mode Exit fullscreen mode

In each form field? Yes, that the draw how server and client exchange the dynamic hypermedia content. Oh My Punk!

Aaaah Too handsome

Whenever the $errors is empty the message isn't appear in that form, but if the $errors variable is not empty then it will display the validation message.

The Validation

Where Is The Table?

Angry

Hold on... don't look at me like that! this is wasting my time. I know, when you choose this topic, you willing to read this and wasting your time also.

Here is the table, but don't complain about the Tailwind Classes and everything is wide and long to read to the right side 🤣 Oh My Punk! this is funny... sorry, I regret. Cz this table is look identical with

In that table what I want to highlight is just the first div!

<div 
    class="overflow-x-auto"
    id="suppliers-table"
    hx-trigger="loadTableSupplier from:body"
    hx-get="<?= base_url('suppliers?' . http_build_query(array_merge($currentPage, ['column' => 'suppliers.updatedAt', 'limit' => 10, 'search' => '', 'order' => 'desc']))) ?>"
    hx-target="this"
    hx-swap="outerHTML"
>
Enter fullscreen mode Exit fullscreen mode

laugh

🤣 Yes! The hx attributes:

  • hx-trigger="loadTableSupplier from:body" is responsible to receive the loadTableSupplier event that sent from the server and come to the client page from:body
  • then the hx-get with their long value that really mess up! But the hx-get will get the latest content from server
  • and the hx-target will placed the content to the element
  • and the hx-swap will replace the entire div with the latest content also display the new supplier inside

🤯 Boom!!!

The Model

The model look pretty clean... and I hate it so much cz I forgot how it's work!

Simple things sometime make me blind. But in the chaotic things, I see the pattern. .darkterminal

<?php

namespace App\models;

use Fckin\core\db\Model;

class Suppliers extends Model
{
    public string $supplierName;
    public string $supplierCompanyName;
    public string $supplierAddress;
    public string $supplierPhoneNumber;
    public string|null $supplierEmail;
    public string|null $supplierCoordinate;

    public string $tableName = 'suppliers';

    public function rules(): array
    {
        return [
            'supplierName' => [self::RULE_REQUIRED],
            'supplierCompanyName' => [self::RULE_REQUIRED],
            'supplierAddress' => [self::RULE_REQUIRED],
            'supplierPhoneNumber' => [self::RULE_REQUIRED],
            'supplierEmail' => [self::RULE_EMAIL],
            'supplierCoordinate' => []
        ];
    }

    public function create(array $data): bool
    {
        $created = $this->table($this->tableName)->insert($data);
        return $created > 0 ? true : false;
    }
}
Enter fullscreen mode Exit fullscreen mode

You can look at thc-fck core of my PHP Framework about the Fckin\core\db\Model. That's it!

😊 Sorry for wasting your time...
