PHP - Dynamically Delete Array Element

Submitted by razormist on Saturday, September 28, 2019 - 14:52.

In this tutorial we will create a Dynamically Delete Array Element using PHP. This code can delete an array element when the delete button in the table row. The code use PHP SESSION to store an array element that display in the table when you use for() loop and by setting an array index position as a argument in array_splice you can delete that array element. This is a user-friendly kind of program feel free to modify it. We will be using PHP as a scripting language and interpreter that is used primarily on any webserver including xamp, wamp, etc. It is being use to any famous websites and it has a modern technology that can easily be use by the next generation.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html. And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
</a>            </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">PHP - Dynamically Delete Array Element</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <?php
                        session_start();
                        if(!ISSET($_SESSION['member'])){
                                $array = ['John Smith'];
                                $_SESSION['member'] = $array;
                                
                        }
                ?>
 
                <div class="col-md-4">
                        <form method="POST" action="add.php">
                                <div class="form-group">
                                        <label>Full Name</label>
                                        <input type="text" name="name" class="form-control" required="required"/>
                                </div>
                                <center><button class="btn btn-primary" name="add">Add</button></center>
                        </form>
                </div>
                <div class="col-md-8">
                        <table class="table table-bordered">
                                <thead class="alert-info">
                                        <tr>
                                                <th>Full Name</th>
                                                <th>Action</th>
                                        </tr>
                                </thead>
                                <tbody>
                                        <?php
                                                $member = $_SESSION['member'];
                                                for($i=0; $i<count($member); $i++){
                                        ?>
                                        <tr>
                                                <td><?php echo $member[$i]?></td>
                                                <td><center><a href="delete.php?index=<?php echo $i?>" class="btn btn-danger">Delete</a></center></td>
                                        </tr>
                                        <?php
                                                }
                                        ?>
                                </tbody>
                        </table>
                </div>
        </div>
</boy>  
</html>

Creating the Main Function

This code contains the main function of the application. This code will delete an array element when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as shown below. delete.php

<?php
        session_start();
        
        if(ISSET($_REQUEST['index'])){
                $index=$_REQUEST['index'];
                $member = $_SESSION['member'];
                array_splice($member, $index, 1);
                
                $_SESSION['member'] = $member;
                
                
                echo "<script>alert('You have deleted one array element!')</script>";
                echo "<script>window.location='index.php'</script>";
        }
?>

add.php

<?php
        session_start();
        
        if(ISSET($_POST['add'])){
                $name=$_POST['name'];
                $member = $_SESSION['member'];
                array_push($member, $name);
                $_SESSION['member'] = $member;
                
                header("location: index.php");
        }
?>
