Content from shortcode within post NOT showing in widget

Hi All,

I have placed the shortcode, for a news ticker (and a RSS fed) into a post. The content from the feed shows up in the post with no problem. However, the content from the shortcode that I placed in the post will not show up in the GK News Slideshow and Tabs widgets. All I see in the widget is the post title and the actual shortcode.

How do I get the content from the shortcode that I placed in the post to show up in the GK News Slideshow and Tabs widgets?

Hi,

Slider and tabs content are filtered from the shortocodes. You can edit News/gavern/widget.slideshow.php file and add this line

Code: Select all

$art_text = apply_filters('the_content', $art_text);

in generate_art_text function, before this line:

Code: Select all

$art_text = $this->cut_text('article_text', $art_text);

and you should remove this line:

Code: Select all

$text = strip_tags($text);

from cut_text function (at the end of file).

Hi,

Thanks for the reply. I was excited to see that it could be done, but after I completed the task, it seems to not have worked. I followed your instructions, but I can still see the shortcode from the posts in the widget.

I have attached the "widgets.slideshow.php" file that I edited. Please take a look at the file to ensure that I edited it correctly.

NOTE: dont forget to add the php extension to the file I uploaded. Your software would not allow me to upload a php file.

Attaching the file didn't work..... here's the code

After editing the code, the appearance of the site changed. I have attached a copy of how it looks.

ALso - I anm using version 1.4 of the theme. I upgraded from version 1.1 with the expectation that it would make a difference. I tried your suggestions in both versions. It did not make a difference. Neither version worked.

FYI - I also tried {loadposition rss1) in a test Joomla 2.5 installation. Didn't work in Joomla either.

Your file seems to to be ok. You can zip your php file and then attach or use code shortcode to paste your code here.

Regarding your issue, it's also don't work with joomla, because it's default behaviour, shortcodes are cut - it's also the same situation with default wordpress post excerpt.

Could you send me a PM with backend access to your website?
