Hello everyone,

 

First off thank you very much for taking the time to read my post.

 

I have a custom Twitter feed reader built in php, it has been working great over the past month or two, but today it stopped working :( The following is the error messages:

 

Warning: simplexml_load_string() [function.simplexml-load-string]: namespace error : Namespace prefix twitter on geo is not defined in /home/*******/public_html/modules/mod_twitter/tmpl/default.php on line 107

And here is the code that we are using:

if (!is_numeric($params->get('tweets'))){

}else{
  $tweets = $params->get('tweets');
}
// This comes before the entire block of tweets.
$prefix = $params->get('prefix');
// This comes after the entire block of tweets.
$suffix = $params->get('suffix');

// Configure relative date and time
function smartTime($time){
  define("SECOND", 1);
  define("MINUTE", 60 * SECOND);
  define("HOUR", 60 * MINUTE);
  define("DAY", 24 * HOUR);
  define("MONTH", 30 * DAY);

$delta = time() - $time;
if ($delta < 2 * MINUTE){
	return "About 1 min ago";
}
if ($delta < 45 * MINUTE){
	return "About ".floor($delta / MINUTE) . " min ago";
}
if ($delta < 90 * MINUTE){
	return "About 1 hour ago";
}
if ($delta < 24 * HOUR){
	return "About ".floor($delta / HOUR) . " hours ago";
}

	return "Yesterday";
}
if ($delta < 30 * DAY){
	return floor($delta / DAY) . " days ago";
}
if ($delta < 12 * MONTH){
	$months = floor($delta / DAY / 30);
	return $months <= 1 ? "1 month ago" : $months . " months ago";
}else{
	$years = floor($delta / DAY / 365);

Ok I think I found the problem it looks like twitter added a new row to it's feed? <twitter:geo> I added this to my code around line 107 and all is well again.

 

I changed this code:

$fed = '<feed>' . $fed . '</feed>';
$fed = str_replace('<twitter:source>', '<twittersource>', $fed);
$fed = str_replace('</twitter:source>', '</twittersource>', $fed);
$fed = str_replace('<twitter:lang>', '<twitterlang>', $fed);
$fed = str_replace('</twitter:lang>', '</twitterlang>', $fed);

 

To this:

$fed = '<feed>' . $fed . '</feed>';
$fed = str_replace('<twitter:geo>', '<twittergeo>', $fed);
$fed = str_replace('</twitter:geo>', '</twittergeo>', $fed);
$fed = str_replace('<twitter:source>', '<twittersource>', $fed);
$fed = str_replace('</twitter:source>', '</twittersource>', $fed);
$fed = str_replace('<twitter:lang>', '<twitterlang>', $fed);
$fed = str_replace('</twitter:lang>', '</twitterlang>', $fed);
