A full description of the issue:

I am testing the Stories module for news and have run in to an interesting problem. I have installed the module on our Linux system which is running PHP 4 and it works fine. I have also installed it on my personal development/test machine (Windows XP) that uses PHP 5 and I am getting a blank page when I go in to the News section. When I go to the Admin I can get into Preferences but not Topics Manager or Post/Edit News (they bounce to the index).

When I turned on all debugging there were no errors. The Apache log file has the following error:

PHP Fatal error:  Using $this when not in object context in C:\xoops-2.0.15\htdocs\modules\stories\class\class.newsstory.php on line 135


From what I can see, the file looks fine. In fact, this is the same file that I copied to the Linux server that is working great. I suspect that this has something to do with the fact that I'm running PHP 5 but I'm not sure what the problem could be.

Re: PHP Error in class.newsstory.php (Stories module)

It is a PHP 5 related problem.

I cannot remember the actual details from when I experienced it first.

I think the problem is that there is a call to $this->something() from within a class function that is called like this:
NewsStory::doSomething()

It is called statically (with :: instead of -> on an object) and then $this doesn't exist in the class function.

Could you paste the whole function code of the function that is around line 135?

Re: PHP Error in class.newsstory.php (Stories module)

Thanks Mithandir. That explanation makes sense although I wonder why PHP 4 would let that slide.

Anyway, the following code is the function containing the problem.

function getPublished($limit=0, $start=0, $topic=0, $author='', $ihome=0, $asobject=true)
    {
        $db =& Database::getInstance();
/*135*/        $this->table = $db->prefix("stories");
        $this->topicstable = $db->prefix("topics");
        $this->vltable = $db->prefix("vlstories");
        $myts =& storiesTextSanitizer::getInstance();
        $ret = array();
        $sql = "SELECT DISTINCT * FROM ".$this->table.", ".$this->vltable." WHERE ".$this->table.".storyid=".$this->vltable.".storyid AND published > 0 AND published <= ".time()." AND (expired = 0 OR expired > ".time().")";
        if ( !empty($topic) ) {
            $sql .= " AND topicid=".intval($topic);
        }
        if ( !empty($author) ) {
            $sql .= " AND author='".$author."'";
        }
        if ( $ihome == 0 ) {
            $sql .= " AND ihome=0";
        } else {
            $sql .= " AND (ihome=1 OR ihome=0)";
        }
        if (!empty($uid) && intval($uid) > 0) {
            $sql .= ' AND uid='.$uid;
        }
         $sql .= " ORDER BY tocid DESC";
        $result = $db->query($sql,intval($limit),intval($start));
        while ( $myrow = $db->fetchArray($result) ) {
            if ( $asobject ) {
                $ret[] = new NewsStory($myrow);
            } else {
                $ret[$myrow['storyid']] = $myts->makeTboxData4Show($myrow['title']);
            }
        }
        return $ret;
    }

I added a comment to line 135. When I commented out all references to $this in the function the same error occurred in another function further down in the class.

The problem is more an academic one for me now as I am switching to News 1.44. It has a better submission page than Stories does.
