将url参数传递给短代码

Question

Background of my question: I created over 300 slideshows. In my WordPress page/post they are activated with a shortcode i.e [masterslider id=15]. I pass the value (id=15) as an url-parameter to my custom-template. i.e //url?nmbr=15. That works. I can echo the value, I can echo the complete shortcode [masterslider id="15"] but the slider doesn't start to show pictures.

of course, I can create one page with 100 shortcodes wich will make the page very slow. I can create 100 pages with one slider but I don't like that.

Some of the fifty different codelines I tried in my own-template.php is: ` '

I also tried ob_start with ob_clean without succes. Please help.

I suspect the moment you apply your short-code value , content for the page is already loaded. So it never gets executed.

So I would try adding the_content filter to add/edit the short-code's ID so it gets changed before content gets displayed.
