There are going to be a few PHP 8 incompatibilties - so this is probably the place to note them down.
Please add to this list if you find any ... JCook is not being developed anymore - so we need to help each other to keep our older websites running.

If you upgrade to PHP 8 and your whole website goes down... its is probably line 384 in libraries/jdom.php (which is loaded for eevry page).

If you swicth on the Joomla Degug mode, you will see this error...
"count(): Argument #1 ($value) must be of type Countable|array, null given"
This is because a emplty variable, a non-array, is being used with the count function.

In libraries/jdom edit file jdom.php line 384

Change

else if (($i !== null) && (count($args) > $i))

else if ($i !== null)

Just call me Chris

This is another bug in the item controller. In /public_html/administrator/components/com_yourcomponent/classes/controller/item.php Line 240 Change: if (!count($cid)) To if (empty($cid)) Just call me Chris The following user(s) said Thank You: jonathanbell

Did you change anything, or never mind ? if ($args[$i] !== null) Warning: Trying to access array offset on value of type null in /home2/user_xxx/public_html/my_site/libraries/jdom/dom.php on line 385 change to if (!empty($args[$i]) )

This is what you call a component builder. I was able to master using this in a very short time and the resulting component works like a charm. Not just a basic component builder but a fully working component builder with forms fields tables all ready to go. You can make the list and item views to display in the front and back end. Also there is a great forum just starting to evolve and I'm sure this will grow very rapidly when you all realise how good this tool is.
