Fix for `undefined function tpt_yield()`

After upgrading from 4.5.7 to 4.6.2, I got this error when trying to load my site:

Fatal error: Call to undefined function tpt_yield() in /mysite/textpattern/publish/taghandlers.php(4344) : eval()'d code on line 2

I was using tpt_yield in one of my forms, inside a <txp:php> block. It seems there’s a new way to call this function now. It took me a little while to figure out, so I’m documenting it here in case anyone else has the problem.

Replace: txp_yield()
With: Txp::get('\Textpattern\Tag\Syntax\Partial')->renderYield()

curious. what does the code actually do?

It’s the PHP equivalent of the <txp:yield /> tag.

I’m using it like this:

<txp:output_form form="my_form">my-file.jpg</txp:output_form>

my_form:

<txp:php>
$imagefile = 'images/'.Txp::get('\Textpattern\Tag\Syntax\Partial')->renderYield();
if (file_exists($imagefile)) { ... }
</txp:php>

??? tpt_yield() ??? Are you sure you did not mistype something?

I think there was a reason for it having a deliberately alternative name. Jukka explained it here.
