Apologies in advance if this is the wrong place for this post and/or numptiness!
I am developing a search page and would like this to output a sentence of background text for each search result. This is easy for calendar events and standard pages which have a metadata description, but a fair proportion of the standard page assets don't have a metadata description and there are a lot of these assets, so it would be a long task to manually add the metadata.
I'm using keyword modifiers for other Type Formats (for instance %asset_attribute_description^maxwords:80% for calendar events) but would like to know if it's possible to nest keyword modifiers so I have a single line of code that looks for the metadata and if this is empty, get the first 50 words of the asset contents.
The ^empty keyword modiifier looks hopeful and %asset_metadata_Description^empty:asset_contents^maxwords:80% works in my head, but not in Matrix as it just outputs the text 'asset_contents' onto the page.
Have tried adapting it with curly brackets, extra % signs and the replace_keywords modifier, but think I may be barking up the wrong tree.
So I guess it boils down to two questions:
1) Is it possible to nest keyword modifiers and if so, what's the correct 'grammar'?
2) If it's not possible, do you have any ideas for a workaround?
Welcome to the forums! You are thinking along the right lines - but note replace_keywords modifier only came in a relatively recent release so check the manuals page to ensure your system is up to date enough. I stress I havent tested this so I may still get the syntax a bit wrong, but I'd expect something like:
I think asset_contents includes the paint layout, so if that has formatting you wouldnt want then you might want to try asset_contents_raw or set up a separate layout and specify it explicitly like asset_contents_paint_X where X is a layout designed to render for search. You might also want to build in the ^striphtml modifier in case there is formatting in the asset contents that you wouldnt want showing in your search results.
Hi Tony and thanks for your help and welcome! I've been lurking for a while, but not needed to post anything up to now...
Have tried a few more variants and discovered you can apply mutliple modifiers to the same var e.g. %asset_contents_raw^maxwords:25^striphtml^trim%, which is fantastic and will come in very handly.
It doesn't look like modifiers can handle different dynamic vars within the same statement though, at least on v 4.18.6 ...
