14468	Shortcode usage causes blog texts to not be output	cymric		"'''System configuration''': PHP 5.2.12 + Zend 2.2.0 running on SunOS 5.10; Wordpress 3.0 + Atahualpa 3.4.4 / 'STRATO Default' 1.5 (= based largely on Kubrick; STRATO is my webhost)

'''Problem''': adding the following code to the theme's functions.php ('foto' is Dutch for 'photo', 'fout' = 'error')
{{{
function shortcode_foto($atts, $content, $code)
{
	return '<span style=""color: red;""><strong>[FOTOFOUT]</strong></span>';
}
add_shortcode('foto', 'shortcode_foto');
}}}
and then using the shortcode [foto] in blogtext can result in the blog text itself disappearing completely from the screen. It is simply not output by Wordpress. The rest of the page looks normal, no missing content, no CSS errors, comments (if there are any) appear normal. After many trial and error I was able to create a text where the addition of a ''single'' letter to the last word in a very normal HTML-paragraph of text means the difference between visible text and non-visible text.

'''Switching themes''': Switching to a different theme, taking care to code the same few lines in the appropriate functions.php file, made no difference. The test cases behaved identically: the post disappeared when asked to view the text with one letter extra.

'''Using a different method of introducing the shortcode to Wordpress''': Originally I wanted to have the code wrapped as a plugin. This already caused the behaviour I reported above. Thinking the instantiation method was awry I coded it in a different way, which made no difference. The functions.php-approach is the third attempt to get the code working. At this point I believe the problem is not related to how I hook the shortcode into the system.

'''Using a different version of Wordpress''': Originally I started out with WP 2.8.5 where the bug raised its head too. I upgraded to WP 3.0, noticing but one difference: I could make the text slightly longer before the problem was triggered.

'''Adding text before the first use of the shortcode''': I can add as much text as I want to the texts before the moment I first use the shortcode without triggering the problem. It is only ''after'' the shortcodes are used that the issue appears.

'''Multiple uses of the shortcode''': I have some documents where the shortcode is used more than the two times of the test cases (4 to 5 times), and those texts are rendered without problem.

'''Access to the test cases''': Since I'm still working on a trial blog, copying over content from an older blog, I do not want to name the URL in public just yet; also I've added some simple HTTP Auth protection. Please contact me via email to get the necessary login information.

'''Possible causes''': For the moment I am not sure whether the problem resides with WP or PHP. Unfortunately I cannot change the PHP interpreter."	defect (bug)	closed	normal		Shortcodes	3.0	normal	duplicate
