Question

I would like a new item to be added to an array if a button is pressed

This is my code…

$engineers = array();

if(isset($_POST['add_user'])){
    $engineers[] = $_POST['engineer'];
    $array_count = count($engineers);
}

All it does is replace the only item in the array rather than add to it, where am I going wrong?

Thanks

The form used is

$dropdown = '<select id="engineer" name="engineer" class="select_engineer" type="text" name="engineer" /><option>Select Diary</option>';
while($row = mysql_fetch_assoc($result)){
    $dropdown .= "\r\n<option value='{$row['user_name']}'>{$row['user_name']}</option>";
}
$dropdown .= "\r\n</select>";

(The list of engineers is populated from a MySQL database).

There isn’t anywhere else that adds to the array, I just want a button that will add the engineers user name to the array

Answer 1

your array resets every time you reload the page.
you have to store the data in cookies or sessions or database or …
simple idea :

<?php
session_start();
if(!isset($_SESSION['engineers']))
$engineers = array();
else
$engineers = unserialize($_SESSION['engineers']);
if(isset($_POST['add_user'])){
    $engineers[] = $_POST['engineer'];
    $array_count = count($engineers);
}
$_SESSION['engineers'] = serialize($engineers);
