<?php
include('includes/db_connection.php');
include('includes/sessions.php');
include('includes/functions.php');
include('includes/header.php');
include('includes/navbar-logged.php');
require_once('api-sape.php');
// init sape
$sape = new SapeApi();
$userId = $sape->login(SAPE_USER, SAPE_PASS);
?>
<style type="text/css">

Once the "search" is pressed, i wanted a loading .gif to appear to show the user it's working (this shows fine) the problem is, the form doesn't seem to be submitting, the if (isset($_POST['search'])) { is not being triggered for some reason, can anyone see anything i have missed?

Answer 1

This is the major problem with W3Schools and people following it.
if (isset($_POST['search'])) {
Will never be sent! Or triggered. You need to check the Network Tab for what all is going to the POST request.
You need to check with:
if (count($_POST) > 0) {
Or something that you are sending.
