escape=tags attribute limitation?

Are there any limitations on using the escape="tags" attribute/value pair on the <txp:meta_description / in the <head /> of a document? Like this:

<txp:meta_description escape="tags" />

When inserted that way – coupled with the format="", inside the <body /> it works fine, output is the textual content of the meta-description of a section stripped of all HTML tags. But in the <head /> the output is a blank line – no output at all.

The same is true for the description meta field of an individual article. :-)

TXP 4.8.8 with PHP 8.1.x.

Re: escape=tags attribute limitation?

Any take on this ?

I can work around the problem by listing individual tags as values for the escape attribute. That works.

<txp:meta_description escape="a,b,i,em,span,strong,trim" />

As the description field for sections only accepts 256 characters, there is not much space for adding block level tags.

No, not specifically in <head />, it just does not play well with the default format="meta". In this case the tag outputs something like

<meta name="description" content="Hey <i>you</i>!" />

which is then filtered via escape. Hence escape="tags" strips out <meta /> tag itself, but escape="i" works as expected. You can surely use

<meta name="description" content='<txp:meta_description format="" escape="tags" />' />

but it would probably be better to limit escape to content.

Re: escape=tags attribute limitation?

Ok, thanks for explaining the limitation(s) with this particular combination. I see now that it is quite a sledge-hammer.

I find it quite useful to be able to use HTML tags or Textile in the section description field and use that as a short introduction type bit of text on list pages.

I will test out your suggestion as an alternative to my workaround. Thank you for that.

Yes, thanks that works perfectly

but it would probably be better to limit escape to content.

I would think so – intuitively I naively (?) expected these escape to work on the content of the description field (in the example in this thread).

Looks logical, will change.

Re: escape=tags attribute limitation?

Great, a test on my local playground: it seems to work just fine. TY.
