Predict no comment form

thebombsite · 2013-10-12 15:45:14

I have a site where there is a small “sidebar” which is displayed vertically alongside the comment form when the form is displayed. If there is no form displayed the “sidebar” is displayed horizontally.

Now I can predict the display of the comment form in most situations using standard Textpattern tags however there is one situation where I can’t and that is when a visitor has just submitted a comment. Comments are, of course, still allowed so my sidebar displays vertically however there is no comment form displayed so it looks a bit stupid.

Is there some code I can use to predict this situation?

You can try to check if commented URL variable is set:

<txp:php>
	parse('<txp:variable name="commented" value="'.(isset($_GET['commented']) ? 'yes' : 'no').'" />');
</txp:php>

<txp:if_variable name="commented" value="yes">
	horizontal layout
<txp:else />
	vertical layout
</txp:if_variable>

Thanks for that Oleg. I’ll give it a whirl in the morning.

If your layout is purely CSS, another (dirty, but radical) solution could be including the appropriate <style> declarations directly in your comment_form.

I’ve used your first suggestion very successfully and can use it in several places at once seeing as it’s giving out a variable. I think I’ll leave your second possibility alone for now. Thanks.

You could simplify that down to, which avoids calling parser() function yourself:

<txp:variable name="commented"><txp:php>
    echo (int) (gps('commented') !== '');
</txp:php></txp:variable>

<txp:if_variable name="commented" value="1">
    <!-- preview -->
</txp:if_variable>

Its also better approach incase you are going to use the same snippet to extract other variables. Mixing PHP in Textpattern markup like that has the potency of leading into security issues, unless you are filtering the values beforehand. Never ever do it otherwise.

If you are using any plugins such as adi_gps, rah_function, smd_if, etc_query etc you could use that one too, since all of these are able to check HTTP GET params too.

Thanks Jukka. I’ll look at the plugins if you feel that it’s safer.
