if_variable and comments_web
Hello again! :)
I have been using this snippet in my comments form:
<a href="<txp:comment_web />" rel="nofollow"><txp:comment_name link="0" /></a>
I realized that this would produce links even for people who didn’t input a website, so I tried to use if_variable to avoid that.
I declared <txp:variable name="web" value='<txp:comment_web />' /> at the start of the comments form, and then used this:
<txp:if_variable name="web"><a href="<txp:comment_web />" rel="nofollow"><txp:comment_name link="0" /></a>
<txp:else /><txp:comment_name link="0" /></txp:if_variable>This still results in a link for comment authors that left no website address, however. If I understand the documentation correctly, that means that txp:comments_web isn’t empty even if the author leaves no website… so is there any way I can use the anchor tag and avoid links to people who don’t give a website? Thanks!

Re: if_variable and comments_web
Hi TWD you do not need the rel="nofollow". In Admin>Preferences>Advanced, there is an option: Apply rel="nofollow" to comments? - Yes No

More exactly, it means that as soon as you have set the variable (with <txp:variable />), it exists. So with <txp:if_variable name="web"> you are only checking for its existance. You should instead check if it’s empty or not:
<txp:if_variable name="web" value="">
<txp:comment_name link="0" />
<txp:else />
<a href="<txp:comment_web />"><txp:comment_name link="0" /></a>
</txp:if_variable>Edit: removed the rel="nofollow", colak already pointed out why ;)

Re: if_variable and comments_web
The easiest way is to use <txp:comment_name /> as it is. What it does:
If email address is supplied and allowed to be viewed, an email link is created. Otherwise, if a website is entered, the website URL is used. If neither is supplied, name displays as plain text.
Check the Wiki entry…
From my comments form on TXP Tips:
<p><txp:comment_name /><br />Output is like on this tip

Let me enjoy this moment – the first and only time I have better advice than Els! ;-)
Seriously, the TXP comments system is quite obtuse and hard to understand sometimes.

Don’t worry, I’m sure it will happen again ;) I just focused on the variable/if_variable tags and forgot to look at the context :)

Re: if_variable and comments_web
Thanks guys! I was going through all this because of I wanted nofollow in there (and completely forgot about the admin option), actually, so I guess that resolves everything! :)
