Pausing RSS scroller JavaScript engine

1) Script Title:
Pausing RSS scroller
2) Script URL (on DD):
http://www.dynamicdrive.com/dynamici...ller/index.htm
3) Describe problem:

php array association syntax error:(filename:scrollbrigde.php:line74)

writen:
echo "rsscontentdata.$divid" . "[$i]={link:\"" . sla****($item[link]) . "\", title:\"" . sla****($item[title]) . "\", description:\"" . sla****($item[description]) . "\", date:\"" . sla****($item[pubDate]) . "\"}\n";

the script above produce notice that prevent browser to work properly (stop at all).


suppose to be:
echo "rsscontentdata.$divid" . "[$i]={link:\"" . sla****($item["link"]) . "\", title:\"" . sla****($item["title"]) . "\", description:\"" . sla****($item["description"]) . "\", date:\"" . sla****($item["pubDate"]) . "\"}\n";

note: since PHP 4.3 array association with text should be using "" mark, otherwise parser will consider it as constant.

I suggest that the outputRSS_JS function be revised to the following:

function outputRSS_JS($url, $divid) {
    global $rss;
    if ($rs = $rss->get($url)){
	    echo "rsscontentdata.$divid=new Array();\n";
	    $i=0;
            foreach ($rs['items'] as $item) {
                echo "rsscontentdata.$divid" . "[$i]={link:\"" . sla****($item['link']) . "\", title:\"" . sla****($item['title']) . "\", description:\"" . sla****($item['description']) . "\", date:\"" . sla****($item['pubDate']) . "\"}\n";
		$i++;
            }
			echo "CurTime = new Date();\n";
            if ($rs['items_count'] <= 0) { echo "rsscontentdata.$divid" . "[0]={link:\"" . "" . "\", title:\"" . "Error" . "\", description:\"" . "Sorry, no items found in the RSS file" . "\", date: CurTime}\n"; }
    }
    else {
		echo "rsscontentdata.$divid=new Array();\n";
		echo "CurTime = new Date();\n";
		echo "rsscontentdata.$divid" . "[0]={link:\"" . "" . "\", title:\"" . "Error" . "\", description:\"" . "Sorry: It's not possible to reach RSS file $url" . "\", date: CurTime}\n";
        // All else fails
		// Prevents other scrollers from freezing due to incorrect data format being sent to Javascript functions
    }
}

The later half (the main "else" statement) has been changed in order to send data to the javascript functions. Without this, any time a single rss file fails to open, all rsspausescrollers on the page will freeze. With this change, only the failed file's scroller will show a problem, which will display error text formatted by the javascript. This should make pages that use multiple scrollers less prone to complete failure.
