how to install / reference Simplepie.php

[swmagic999]

We've taken an old site (pre-3 WP) and upgraded to 3.4.2. But we are getting an error on a page:

Code: Select all

Warning: array_slice() expects parameter 1 to be array, null given in /home/content/k/p/w/kpw2006/html/4/wp-content/themes/calhousing/template-rss.php on line 51

Warning: array_reverse() [function.array-reverse]: The argument should be an array in /home/content/k/p/w/kpw2006/html/4/wp-content/themes/calhousing/template-rss.php on line 52

Warning: Invalid argument supplied for foreach() in /home/content/k/p/w/kpw2006/html/4/wp-content/themes/calhousing/template-rss.php on line 54

I installed WP-Debug, et.al. to discover that template-rss.php has been deprecated as of WP 3 and it recommends using Simplepie.php.

Message in WP-Debug "Use wp-includes/class-simplepie.php instead.
Deprecated in version 3.0."

How do I fix WP to reference that?

have you looked at the file "class-simplepie.php" in the /wp-includes/ folder?

I'm not familiar with it myself, but it sounds like it has the functionality you seek. i would explore the file to get function names etc and once you've found what you're looking for, go to appearance>editor>header.php and add a require() or include() for the file and update your function calls to the new function names

OK, this is a good first pass idea.

Now, I've noted that there's 477 functions. How do I discover which ones I need?

step one is identifying the deprecated functions that you were trying to use initially. Then identify what they do, hopefully the function names will be descriptive enough to remove a lot of the guesswork there. then browse through the code or documentation for the class-simplepie.php for functions with similar names. in the event that function names in one or both files are less than helpful, you can write up signatures for the deprecated functions; name, input parameters, return value and type. then go through simplepie looking for similar signature. Or you could just google for documentation, but I assumed you had already done
