Dans ce didacticiel PHP CRUD, nous allons créer une application PHP CRUD entièrement fonctionnelle avec Bootstrap 5, PHP et MySQL.

PHP CRUD signifie Créer, Lire, Mettre à jour, Supprimer, ce qui est un moyen facile de mémoriser tous les composants nécessaires à une application de site Web entièrement dynamique. Nous allons utiliser des instructions MySQL appelées INSERT , SELECT , UPDATE et DELETE qui correspondent à la fonctionnalité CRUD.

Vous allez aussi apprendre à ajouter des données dans une basse de données, de supprimer un étudiant, ajouter un étudiant, de mettre à jour les informations d’un étudiant, de lister les étudiants ainsi que leurs détails. vous allez aussi apprendre à utiliser les classes Bootstrap, de faire la responsivités etc.

Pour un didacticiel vidéo complet de ce tutoriel application CRUD PHP, vous pouvez regarder la vidéo YouTube donnée. Nb: n’oubliez de visiter les autres vidéos disponible sur la chaine et n’oubliez pas aussi de vous abonner à la chaine pour

Avant de commencer, vous devez au préalable se rendre dans phpMyAdmin pour créer une base de données.

Ensuite nous passons directement à la création de notre fichier de configuration php qui nous permet de faire connecter la base de données récemment crée au niveau de phpmyadmin avec notre travail.

Créez un fichier avec le nom connect.php. copiez et collez les codes donnés dans votre fichier PHP. N’oubliez pas que vous devez créer un fichier avec une extension .php

				
					<?php 
 $con = mysqli_connect('localhost', 'root', '');
 	if (!$con) {
 		die("database connection failed" . mysqli_error($con));
 	}

 $select_db = mysqli_select_db($con, 'php_crud_app');
 	if (!$select_db) {
 		die("database selected failed" . mysqli_error($con));
 	}

 ?>
				
			

Ensuite Créez un fichier avec le nom navbar.php. qui nous permet de créer la barre de navigation entre les différentes pages qu’on va crée par la suite; copiez et collez les codes donnés dans votre fichier PHP. N’oubliez pas que vous devez créer un fichier avec une extension .php

				
					
<nav class="navbar navbar-expand-lg navbar-light bg-nav">
  <div class="container-fluid">
    <a class="navbar-brand" href="#">Sen Dev Tech</a>
    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarText" aria-controls="navbarText" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbarText">
      <ul class="navbar-nav m-auto mb-2 mb-lg-0">
        <li class="nav-item">
          <a class="nav-link active" aria-current="page" href="view.php">Home</a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href="index.php">Ajouter un Etudiant</a>
        </li>
    
      </ul>
      <span class="navbar-text">
        Profil Admin
      </span>
    </div>
  </div>
</nav>
				
			

Créez un fichier avec le nom index.php. copiez et collez les codes donnés dans votre fichier PHP.

				
					<?php 

require_once ('connect.php');
	if (isset($_POST) & !empty($_POST)) {
		$nom = ($_POST['nom']);
		$prenom = ($_POST['prenom']);
		$email = ($_POST['email']);
		$gender = $_POST['gender'];
		$age = $_POST['age'];

		$CreateSql = "INSERT INTO `etudiant` (first_name, 	last_name, email, gender, age)  VALUES('$nom', '$prenom', '$email', '$gender', '$age') ";
		$res = mysqli_query($con, $CreateSql) or die(mysqli_error($con));
		if ($res) {
			$message = "insertion reussi avec succès";
		}else{
			$erreur = "erreur d'insertion a la base";
		}
	}
