class making page blank
 
this is my first ever class so i'm not sure why it's going wrong or where but hey it's the only way i'll learn right?

could someone tell me where i'm going wrong, it's based off of Boofo's stats serialize hack

PHP Code:
<?php

class DoStats
{

    var $prs_stats = array();
    var $updatetime;
    // var TIMENOW;

    function DoStats($prs_stats, $updatetime)
    {
        $this->updatetime = $updatetime;
        //$this->prs_stats = $prs_stats;

        if (!$this->prs_stats['lastupdate'])
        {
            $this->prs_stats['lastupdate'] = 0;
        }

        if ($prs_stats['lastupdate'] == 0 OR ($prs_stats['lastupdate'] + ($this->updatetime * 60)) < TIMENOW)
        {
            $starttime = mktime(0, 0, 0, date('m'), date('d'), date('Y'));

            // Total Pieces
            $stats_totalpieces = @$DB_site->query_first("

                FROM prs_pieces
            ");

            // Total Reviews
            $stats_totalreviews = @$DB_site->query_first("
                SELECT COUNT(*) AS count
                FROM prs_reviews
            ");
    
            // Average Rating
            $stats_avgrate = @$DB_site->query_first("
                SELECT AVG(rating) AS avg
                FROM prs_rating
            ");

            // Top Rated Piece
            $stats_toprated = @$DB_site->query_first("

                LEFT JOIN prs_pieces ON (prs_pieces.pieceid = prs_rating.pieceid)
                ORDER BY count
                DESC LIMIT 1
            ");

            // might need to change this into a quick query of select from piece 'review_count' order by review count
            // Top Reviewed

Dont you have to make an new instance of the class? I can be completly wrong...

sabret00the 06-23-2005 04:54 PM
i don't think so, i.e. it's called in my page via
PHP Code:
$makestats = DoStats($prs_stats, 15);
$prs_stats = $makestats->StatsFormat($make_stats); 

calorie 06-23-2005 05:24 PM
Code:

    function DoStats($prs_stats, $updatetime)
    {
        global $DB_site;
        $this->updatetime = $updatetime;
        ...

calorie, i am so so so so so grateful to you, you dont' know how much, this has been bothering me since yesterday, thank you very much for helping my first class come to life, unfortunately i never finished my database schema in order to test it properly, but it is throwing up the correct errors, thank you again :)

calorie 06-23-2005 05:46 PM
Blush, no problem, glad I could help. :)

sabret00the 06-23-2005 06:55 PM
Ok now i've finished the database scheme (i guess this is what you get from coding from the front-end)

i'm getting this when i do a print_r on the $makestats
PHP Code:
$makestats = new DoStats($prs_stats, 15);
$prs_stats = $makestats->StatsFormat($makestats);

print_r($makestats); 
it's giving me this
PHP Code:
DoStats Object ( [DoStats] => Array ( [totalpieces] => 1 [totalreviews] => 0 [avgrate] => 0 [toprated] => [toprated_pieceid] => 0 [topreviewed] => [topreviewed_pieceid] => 0 [topviewed] => [topviewed_pieceid] => 0 [topposter] => [topposterid] => 0 [topreviewer] => [topreviewerid] => 0 [lastupdate] => 1119559839 ) [GetStats] => Array ( [0] => Array ( [totalpieces] => 1 [totalreviews] => 0 [avgrate] => 0 [toprated] => [toprated_pieceid] => 0 [topreviewed] => [topreviewed_pieceid] => 0 [topviewed] => [topviewed_pieceid] => 0 [topposter] => [topposterid] => 0 [topreviewer] => [topreviewerid] => 0 [lastupdate] => 1119559839 ) [1] => Array ( [0] => Array ( [totalpieces] => 1 [totalreviews] => 0 [avgrate] => 0 [toprated] => [toprated_pieceid] => 0 [topreviewed] => [topreviewed_pieceid] => 0 [topviewed] => [topviewed_pieceid] => 0 [topposter] => [topposterid] => 0 [topreviewer] => [topreviewerid] => 0 [lastupdate] => 1119559839 ) ) ) ) 
it's got 4 arrays in the makestats instead of just overwriting it and giving me the last one, how would i remedy this?

the bit in question (making the $makestats->GetStats[$var]) is
PHP Code:
    function StatsFormat($prs_stats)
    {
        foreach($prs_stats AS $key => $value)
        {
            if (is_numeric($value))
            {
                $this->GetStats[] = vb_number_format($value);
            }
            else
            {
                $this->GetStats[] = $value;
            }
        }
        return $this->GetStats;
    }

thanks though i managed to fix it by changing
PHP Code:
        return $this->GetStats; 
into
PHP Code:
        return $this->GetStats['0']['1']; 
but i reckon yours is the cleaner code.

though i have one more problem, sorry about this.

debugging the code i have
PHP Code:
$prs_stats1 = unserialize($datastore['prs_stats']);
echo $prs_stats1 . "<--";
print_r($prs_stats1);
$makestats = new DoStats($prs_stats1, 15);
$prs_stats2 = $makestats->StatsFormat($makestats); 
the problem is though, that $prs_stats1 is returning nothing, while $datastore is giving the correct array, it's like $prs_stats1 isn't unseralizing.

the reason $prs_stats1 is go relevant is because of the conditional in the first method of the class that saves me 8 queries

Do a print_r on $datastore and see if there is a value for the prs_stats key.
