Need input to resolve this... please :)

Haven't been here in a while but I have stumped myself at the moment or maybe I've looked at it too much LOL

 

This is what I have and it does work but gives me errors on my page...  This is my helper.php:

 

​function truncText($text, $chars)
{
if (strlen($text) <= $chars) return $text;
$new = wordwrap($text, $chars, "|");
$newtext=explode("|",$new);
return $newtext[0];
}

function getRSS( $params )
{
$doc = new DOMDocument();
$doc->load($params->get( 'feed', 'http://googleblog.blogspot.com/atom.xml' ));
$arrFeeds = array();
foreach ($doc->getElementsByTagName('item') as $node) {
if ($i >= $params->get('numitems',5)){ break; }
$arrFeeds[$i]->title = $node->getElementsByTagName('title')->item(0)->nodeValue;
$arrFeeds[$i]->desc = self::truncText($node->getElementsByTagName('description')->item(0)->nodeValue, $params->get( 'desclen', 120));
$arrFeeds[$i]->link = $node->getElementsByTagName('link')->item(0)->nodeValue;
$arrFeeds[$i]->pubDate = $node->getElementsByTagName('pubDate')->item(0)->nodeValue;

$i++;
}

return $arrFeeds;
}
 }

 

The error I am getting is this:

 

Notice: Undefined variable: i in helper.php on line 33

 

Notice: Undefined variable: i in helper.php on line 34

 

Warning: Creating default object from empty value in helper.php on line 34

So there you have it... not sure how to fix it... Any help is appreciated to show me the errors of my ways...

You need to define things before you try to use them. You try to use $i without giving it a value anywhere, and you do

$arrFeeds[$i]->title

without first setting $arrFeeds[$i] to anything.

 

Set $i=0, I assume, before you try to use it, and initialize the values in $arrFeeds with $arrFeeds[$i] = new stdClass();
