is_front_page returns false - if used after the loop starts

[christian_gnoth]

hello,
I am using is_front_page() on different places in my theme template files.

It returns for the front page and home page true if I call it inside the loop - if I call it before the loop starts ( if(have_posts()) ) it returns false for the front page. it also returns false if I call it in my functions.php file in a customized excerpt action hook.

Can't reproduce. Are you using query_posts() by any chance?

sorry, it was written wrong - it returns outside true and inside false. and I am using query_posts.

Problem is, that I am showing on my front page an excerpt and I have a customized excerpt function - in that customized excerpt function I am testing if it is front page or not and return different content. (​http://wp-theme-t1.it-gnoth.de)

if query posts is teh reason - it should be possible to show different posts on the front page and still the function returns true.

Please post a snippet of code that reproduces this on any install.

$biq_theme_options = biq_get_theme_options();

I can't reproduce anything with that code per se, but it is obvious why is_front_page is returning two different values. Between calls, you call query_posts(), which resets the query object and changes all of the conditionals to reflect the new query.

If you don't want to alter things that low-level, then using get_posts or a new WP_Query will suffice.

Also, if you're going to use $_SERVER['PHP_SELF'], better not to use it, but if you do, then make sure you escape it. ​http://markjaquith.wordpress.com/2009/09/21/php-server-vars-not-safe-in-forms-or-links/
