Unsupported operand type?

Ich habe zu sagen, ich bin völlig ahnungslos in Sachen PHP, ich weiß genug, um moderate, meine Seiten zu einem akzeptablen Umfang. Ich habe ein bisschen Mühe mit phpauction GPL, immer, wenn ich Sie auf eine meiner Kategorien, bekomme ich diese:

Fatal error: Unsupported operand types in /home/retrorea/public_html/tradepost/browse.php on line 175

Dies ist, was der Linie 175 liest...

$left_limit = ($page-1)*$lines;

Hier ist der rest von dem code.

Jegliche Hilfe würde sehr geschätzt werden. Danke!

vielleicht sollten Sie sich bewegen $lines = (int)$lines; obige Zeile 175? In dem code, den Sie zur Verfügung gestellt, es scheint, dass $lines ist nicht einmal definiert, noch.
Dein code ist inkonsistent, Variablen sollten im gleichen register geführt wird, in Ihrem Fall haben Sie variable $PAGE und $page es ist nicht das gleiche.
Nur tun var_dump auf die Variablen $page und $Zeilen und sehen, welche Arten Sie sind.
Wo sind $page & $lines definiert?

Zwingen Sie den Wert ein integer sein, die Nutzung intval.

versuchen Sie, diesen code rechts oben die Zeilen:
```
echo "<pre>";
var_dump($lines, $page);exit;
```
was wahrscheinlich passiert, ist Ihr immer ein boolescher Wert oder null oder einige andere Daten-Typ-multipliziert mit etwas, das es kann sich nicht mehr vermehren mit. dieser code wird Ihnen sagen, den Daten-Typ der beiden Variablen.

Werden Sie probablly am Ende umschließt, die Zeile in etwa wie folgt:
```
if(is_numeric($lines) && is_numeric($page)){ ---your code---- }else{$left_limit = --whatever your want as default value-- }
```

Versuchen Sie dies:
```
$left_limit = ((int)$page-1)*(int)$lines;
```
