Why won't my snippet call another snippet?

I created a test snippet called runSnippet.



When I call this snippet from a template with [[runSnippet]] (or [!runSnippet!]), it will display the value of documentObject[’content’], but it will not run the AjaxSearch snippet. I’ve tested AjaxSearch on its own and it worked so I know it’s installed properly. I don’t know why it won’t work when called from a snippet. What am I missing?

Hmm, I put an echo in front and now it works. I didn’t think that was necessary. If there’s a better solution, please post it.

You need to use ’echo’ or capture the output into a variable and use ’return’ to output it to the page. The runSnippet() method always returns the string output of the snippet being called so it’s up to you to process the output.

Try something like this:

I prefer this to echo, explicitly returning the content from the snippet. This way the parser is in full control of where the output goes. Otherwise, it’s just echo’d into the output buffer at the point of execution.

Excellent, thanks! I’m curious though, was there any specific reason for the <pre> tags?

No, was just exemplifying how to store the content into a string.
