Lovely little walkthru - thank you!
Because I wanted the planet pages to look like the basic pages, I copied some code and now my planet.php looks like:
<?php
include("./head.inc");
?>
<h2>Type: <?= $page->planet_type ?>, Age: <?= $page->planet_age ?> years</h2>
<p><?= $page->planet_summary ?></p>
<?php
echo $page->body;
include("./foot.inc");
?>
I then added the body field to my planet template. My intention is to write additional content to supplement the planet_summary. When I edit the Earth or Jupiter pages by pasting
A <?= $page->planet_type ?> is a planet that is composed primarily of silicate rocks or metals.
into the Body editor, after switching it to HTML Source editing mode, the result is not what I expected. Can't I mix PHP in with pure content? Or do I have to use some special templating syntax?
