i want to add som php code to home_main.tpl, how to do?

You can't add php code to templates, you need to add it to the php files - what exactly are you trying to do?

[Shamun]

You can add php code to the .tpl files using {php}{/php} but for simplicity you should be adding it to a .php file outside of the /skin1/ directory tree.

Sorry, I should have said 'It is not good practice to add php to the templates'

[sinobest]

for example, i want to add the following php code to x-cart:

<?php
// Include Wordpress 
define('WP_USE_THEMES', false);
require('../../wp/en/glasses/wp-load.php');
query_posts('showposts=5');
?>
<?php while (have_posts()): the_post(); ?>
<h2><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h2>
<?php the_excerpt(); ?>
<p><a href="<?php the_permalink(); ?>">Read more...</a></p>
<?php endwhile; ?>

how to do?

tks.

Just so you know, it probably won't work.
If Wordpress has any php functions with the same names as in X-cart (which is likely) then you'll have errors. You will probably have session problems as well.

As for how, I believe you'll need to put that into init.php
You will also need to assign the php variables as smarty variables to call via {$variable} in your template.

Your wanting to use non-xcart and non-smarty code in an xcart and smarty environment. Not to mention wordpress is huge...

You should talk to qualiteam, bcse etc. if you really want it done.

To avoid conflicts with X-Cart you should pull the Wordpress posts using an RSS feed. I created a Smarty plugin to do this. Create a file include/templater/plugins/function.sr_wpfeed.php with this code:

PHP Code:

<?php
if ( !defined('XCART_START') ) { header("Location: home.php"); die("Access denied"); }

  $smarty->assign($var, $posts);
}
?>

The sample usage comments in the code shows what you can drop into your desired .tpl file to display the posts.
