evaluate and default

colak · 2020-08-15 07:21:16

I know I could use variables but this was just an experiment. The default global has an odd behaviour when used in the context below returning 1 if the image’s alt field has, or has not been filled. Is this expected?

<txp:images id="##">
<txp:evaluate test='<txp:image_info type="alt" />' default="alt text" />
</txp:images>

Actually, nothing is expected in this case, since <txp:evaluate /> expects either content or query attribute to be provided. But we can tweak it to cover such situations too.

But why wouldn’t you use just

<txp:image_info type="alt" default="alt text" />

I could. This was just an experiment:)

Will work as expected in 4.8.3 :-)
