事实上,我无法更新数据
请帮我解这个代码。我更新时找不到任何错误
谢谢。正在查看您的SQL更新语句
UPDATE news set title =?, short_desc =?, isi =?, author =?, status =?, category =? WHERE newsid =?
我能数到7个参数。当我看到你的bind_参数
调用
$sql->bind_param('aaaaa',
$title,$short_desc,$isi,$author,$status,
$date_period_start, $date_period_end, $category);
我计算了5个类型字符(
'aaaaaa'
)和8个参数($title、$short\u desc、$isi、$author、$status、$date\u period\u start、$date\u period\u end、$category
)。这些都需要匹配。阅读可能会有所帮助。绑定参数中的aaaa无效,它需要是s表示字符串,i表示整数,d表示双精度。是的,我已经在8参数中更改了它。但仍然不起作用。非常感谢。
$sql->bind_param('aaaaa',
$title,$short_desc,$isi,$author,$status,
$date_period_start, $date_period_end, $category);
