Неподдерживаемый тип операнда?

/ 24 марта 2012

Я должен сказать, что совершенно не разбираюсь в PHP, я знаю достаточно, чтобы модерировать свои сайты до приемлемой степени.У меня небольшие проблемы с phpauction GPL, когда я нажимаю на одну из моих категорий, я получаю следующее:

Неустранимая ошибка: неподдерживаемые типы операндов в /home/retrorea/public_html/tradepost/browse.phpв строке 175

Вот что в строке 175 читается ... 

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

Вот остальная часть кода.

Чтобы значение было целым числом, используйте intval.

попробуйте добавить этот код прямо над этими строками: 

echo "<pre>";
var_dump($lines, $page);exit;

вероятно, что вы получите логическое значение или ноль, или какой-либо другой тип данных, умноженный на то, с чем он не умножаетсяэтот код сообщит вам тип данных обеих этих переменных.

Вы, вероятно, в конечном итоге заключите эту строку в нечто вроде этого: 

if(is_numeric($lines) && is_numeric($page)){---your code----}else{$left_limit = --whatever your want as default value--}

Попробуйте это: 

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