Question

I am trying to include an image from an external website into a page in the wiki.

I've set the appropriate Config flag to allow included URLs.

This line of code works:

%INCLUDE{raw="on" pattern="^.*?original_image\",[ ]*\"(.*?)\".*" "http://www.amazon.co.uk/gp/product/0764526413" }%

giving this:

BUT, put this into a SEARCH which looks for specific pages in the wiki which hold an ISBN as a meta data item, and it fails to work:

%SEARCH{"$" scope="topic" regex="on" nosearch="on" nototal="on" format="| %INCLUDE{raw="on" pattern="^.*?original_image\",[ ]*\"(.*?)\".*"  "http://www.amazon.co.uk/gp/product/$formfield(ISBN)"}% |" }%

I get " Failed to include URL http://www.amazon.co.uk/gp/product/0764526413". It gets the META ISBN data ok, but doesn't get the image.

If I replace '$formfield(ISBN)' with a real ISBN number, it works fine.

I've bashed my head against a wall for a long time on this. Can anyone help fix it?

Answer

If you answer a question - or have a question you asked answered by someone - please remember to edit the page and set the status to answered. The status is in a drop-down list below the edit box.

The INCLUDE fires off before the SEARCH. You need to delay it until after. Do that by escaping the % sign inside the format:
format="| $percntINCLUDE{ raw=\"on\" pattern=\"...\"}$percnt |"

Thanks Peter. Worked a treat. I got my escapes muddled up!
