PHP How do we check for logged in?

Hi All,
I have a little project going here. I need to know how to check to see if a customer is logged in please.

Thanks in advance,
John

If the customer is logged in, then the value of $_SESSION['customer_id'] will contain their customer number.
If that value is blank or is not set, they're not logged in.

So this should work then?

echo 'Logged in customer id is: ' . $_SESSION['customers_id'];

It doesn't give me the id. Why not?

Thanks Dr.

Ahhh that's why it wasn't working!

echo 'Logged in customer id is: ' . $_SESSION['customers_id'];
should be
echo 'Logged in customer id is: ' . $_SESSION['customer_id'];

I have eyes like an Eagle! LOL

Thanks. I'm sure I'll be back for more later.

Thanks again,
John

['customers_id']

Look at DrByte's original post:

['customer_id']

OK good, you found it!

Hi All,
Is this a good way to test if the customer is logged in?

<?php

  if ($_SESSION['customer_id'] < 1) {
   echo 'Not Logged In!';
   } else {
   $testQuery = mysql_query("SELECT customers_firstname FROM customers WHERE customers_id = '".(int)$_SESSION['customer_id'] ."'");
   while ($customerName = mysql_fetch_assoc($testQuery)) {
   echo $customerName['customers_firstname'] ." ". $_SESSION['customer_id'];
   }
   }
   
   ?>

Please don't be to harsh I'm learning and I'm also sensitive.:yes:

Thanks,
John

Also:

I have cloned the About Us page. In the templates > MyTemp > templates >tpl_new_page.php I am trying to submit a form.

This is the php I'm using to submit. However it is not writing to the DB. Am I missing something here? Like a db connect? I figure we're already connected at this point.

   <?php
   $clientCustomersID = $_SESSION['customer_id'];
   $websiteURL = serialize($_POST['websiteUrl']);
   $keywords = serialize($_POST['keywords']);
   $description = serialize($_POST['description']);
   
   //Inject Customers website into client side DB
   
      if($_SERVER['REQUEST_METHOD']=='POST') {
   
      $qur="INSERT INTO websites (`customers_id`,`url`,`keywords`,`description`)values ('$clientCustomersID','$websiteURL','$keywords','$description')";
   }

  ?>
```Thanks,
            John

Okay,
Got this part. Got it to inject. May have more questions here in a bit though.

Thanks,
John
