The price of every image could, for instance, be calculated as Width * Height – how would I do that in the panel, and how could I then show it in such a nice box? (That’s not an Info field, is it?)
One thing that I noticed when copy+pasting from the docs page
was that the example code for the shop.php model file doesn’t contain the PHP opening
<?
line – for quick copy+pasters like me, it might be helpful to put it there (especially as that file doesn’t necessarily throw a particularly visible error message)?
Yes, you are right, but if you use an IDE that creates PHP files with the opening PHP tag already included (should be <?php not the short <? tag), it can be just as annoying to have to remove it;)
