How To Allow Certain HTML tags in Customization


(Yyhmsg) #1

I’m trying to add the google custom search engine to the header of our discourse forum. I put in the javascript to the head tag and then in the body there is something like <gcse:search linkTarget="_self"></gcse:search> - which will show the google custom search engine.

When I put this in and save it however, it doesn’t show up on the site. I imagine it is being removed by some sort of html filter? (and I should add that by “doesn’t show up” I mean the code itself, not just that the javascript isn’t loading somehow - when I surround it with <!-- -->, the code passes through, but obviously doesn’t work).

Is there a way to get this to pass through?

Thanks!

Looking at this it apparently strips gcse - so I get:

<search linktarget=\"_self\"><\/search>

Which doesn’t load anything

Instead of <gcse:search linkTarget="_self"></gcse:search> it strips out the : and the /gcse

I tried <gcse\:search><\/gcse\:search> but then I get <gcse search> (no : ) and </gcse> (no : or search)

Is there another way to get a variable to pass through the customization editor so that I can get it to show up?

This is just a proof of concept, so you’ll have to play around with it to see how/if it can work for your needs. Try adding this to the </head> tab of a theme:

<script type="text/discourse-plugin" version="0.8.18">
    api.decorateWidget('header-contents:after', helper => {
        return helper.rawHtml(`<gcse:search linkTarget="_self"></gcse:search>`);
    });
</script>

(Edit: improved the answer a little after having more time to look at it :slightly_smiling_face:)

That’s awesome - Thanks! Works perfectly. Both versions seemed to work the same, but I went with your current edit.

Actually I may have spoke a little too soon… It’s fairly intermittent when it will show up. I had both versions of your script in so I thought this newer one was working (and it did once - minus putting the search bar on top of the menu, etc. - lower half of the header).

The first script appears to work on the front page only if I put in at the body close section - then it shows up at the top of the page oddly.

I’d like to try to get it right below the header bar on top on every page.

Instead of ‘header-contents:after’ - is there a ‘body-contents:before’? that I could try. I went through the api docs, but couldn’t find anything that showed such a declaration…

Sure, if you change it from header-contents:after to just header:after, that should do the trick. You will need to style it with CSS to get it exactly how you want it, but that should get you on track :slightly_smiling_face:
