rssdisplaybox Fatal error: Call to a member function set_feed_url()

[student101]

1) Script Title:
rssdisplaybox

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamici...rssdisplaybox/

3) Describe problem:

I kept getting location of cache folder errors
now the local errors are

PHP Fatal error: Call to a member function get_permalink() on a non-object in outputbody.php on line 11

the online errors
rssdisplaybox
or
demo

Fatal error: Call to a member function set_feed_url() on null in

Any ideas or fix? please

The first (local) error is because $item is a value but it isn't an object. The next (online) errors are because $feed is a null value. Posting your custom outputbody.php and main.php code and what version of SimplePie would help.

These errors are related to the SimplePie php statements. It would take someone familiar with SimplePie to directly help (I stopped looking at the code after scrolling through the 2nd 3000+ line file.) You could ask on the SimplePie support forum.

I did see that the code is using indirect (variable) referencing. This is one of the things that changed in php7. What version of php are you using on the online system, as this code may need to be updated to run under php7, so that it returns the correct values to the calling code?

Edit: and since you are getting different errors on your local and online systems, what php version are you using on your local system?

installing new xampp with php 7 to test

[DyDr]

For the code using the latest SimplePie version, this is nonsense logic.

$feed is the instance of SimplePie. You would call the SimplePie methods using $feed->method_name_here...()

$rsslist should be an array of the rss feed ids and urls, like in the 1st code. The rest of the code should get the appropriate URL from the $rsslist array and call the SimplePie methods with that URL.

AFAIK, to convert the 1st code to use the latest SimplePie, after you make the autoloader change, you should only need to change the names of the SimplePie methods that are being called. I don't specifically know what these are, but I did see a list of old/new names on the SimplePie web site. The logic being used in the 1st code, related to $feed and $rsslist should remain the same.

Edit: The blank page may be due to the errors occurring in the code, but could be due to the short opening php tags - <? You should always use full opening php tags - <?php
