Call to a member function get_uri() on a non-object in simplepie/library/SimplePie/Misc.php on line 83

Hi there,

I'm using your very wonderful code but I noticed that I run into this problem:
Call to a member function get_uri() on a non-object in simplepie/library/SimplePie/Misc.php on line 83

I really don't have an idea why this is happening.

Kindly guide me how to fix this one.

Thanks!

[hakimihamdan88]

yeah, im getting those error too

Same here...

Yeah, too bad no one is answering here. :(

When I enter this URL: http://bfgb.wordpress.com/feed/
I get this error: Fatal error: Call to a member function get_uri() on a non-object in D:\xampp\htdocs\simplepie\library\SimplePie\Misc.php on line 83

What's the problem?!

I just got this error using a fresh git checkout on an Ubuntu box.

PHP Fatal error:  Call to a member function get_uri() on a non-object in /path/git/simplepie/library/SimplePie/Misc.php on line 83

Perhaps change Misc.php since SimplePie_IRI::absolutize can return false.

public static function absolutize_url($relative, $base)
{
    $iri = SimplePie_IRI::absolutize(new SimplePie_IRI($base), $relative);
    // return $iri->get_uri();
    if($iri) return $iri->get_uri();
}

However, making that change results in:

PHP Notice: This XML document is invalid, likely due to invalid characters. XML error: > required at line 1110, column 141 in /home/david/www/git/simplepie/library/SimplePie.php on line 1374

Thanks for reporting this issue! In future @hakimihamdan88, it's not necessary to CC me as I get notified of all issues automatically. I would have responded sooner, but it has been a busy week. :)

I'll take a look into this. @gsnedders, want to check this when you check #219? This also seems like somewhere we need unit tests too.

For those reporting this issue: can you var_dump() the parameters being passed in to SimplePie_Misc::absolutize_url() please?

public static function absolutize_url($relative, $base)
{
$iri = SimplePie_IRI::absolutize(new SimplePie_IRI($base), $relative);
return $iri->get_uri();
}

That is where the error happens. When I try to var dump $relative and $base using this feed: http://bfgb.wordpress.com/feed/,
This are the results:
var_dump($relative)
Result:
string(31) "http://bfgb.wordpress.com/feed/"

The error happens when this code is being run return $iri->get_uri();

Your help would be greatly appreciated since we are already using your library in our live site.

Thanks!

Is there any workaround ?

I am getting this error on $item->get_content() as well:

get_items() as $item): ?> get_permalink(); ?> get_title(); ?>

Posted on get_date('j F Y | g:i a'); ?>

get_content(); ?>

[mazard]

Same problem here.

base:http://www.mnac.cat/?lan=002
relative:http://www.flickr.com//photos/73401757@N05/sets/72157630431743284/show/

It looks like there is a problem in the url validation, I think in my case the problem is the '@'.

As a fast workaround I replaced the is_valid function to return always true.

public function is_valid()
{
        return true;
    }

It seems to work fine, I don't know if it can cause any other problems but its not breaking my production site at least.

Regards!
mazard

@mazard Is that the function in the IRI.php?
This is the function

public function is_valid()
{
$isauthority = $this->iuserinfo !== null || $this->ihost !== null || $this->port !== null;
if ($this->ipath !== '' &&
(
$isauthority && (
$this->ipath[0] !== '/' ||
substr($this->ipath, 0, 2) === '//'
) ||
(
$this->scheme === null &&
!$isauthority &&
strpos($this->ipath, ':') !== false &&
(strpos($this->ipath, '/') === false ? true : strpos($this->ipath, ':') < strpos($this->ipath, '/'))
)
)
)
{
return false;
}

return true;

}

I remove everything but retained return true, but the error still exists :(

I think it chokes on that %21 at the end of the "embed youtube" link

Hope this helps!

[woody0130]

is there an ETA on a fix for this? My customer is getting very anxious...

[booruguru]

I'm having the same problem with the feed --- http://rss.cbc.ca/lineup/topstories.xml

Note: The error is preventing my page from fully rendering. Any suggestions on how I force the page to load fully despite this (or any future) errors?

[cookiejest]

Hi,

I think this problem is being caused if the URL contains numbers for some reason.

My code works with other feeds that have no numbers but not with http://rss.cnn.com/rss/edition_business360.rss

With this feed I get the error quoted above.
