好的,所以我正在尝试更新博客条目,当我尝试运行脚本时,我正在调用非对象上的成员函数 bind_param().我已经做了大量的研究,想看看我是否可以自己修复它,但我一定遗漏了一些东西.
Okay, so I'm trying to update a blog entry, and I'm getting Call to a member function bind_param() on a non-object when I try to run the script. I have done extensive research to see if I could fix it myself, but I must be missing something.
<?php
$stmt = $mysqli->prepare("UPDATE blogentries SET
headline = ?,
image = ?,
caption = ?,
article = ?
WHERE id = ?");
$stmt->bind_param('ssssi',
$_POST['headline'],
$_POST['image'],
$_POST['caption'],
$_POST['article'],
$_POST['id']);
$stmt->execute();
$stmt->close();
?>
提前致谢,

更新:这是数据库连接
我添加了额外的 $mysqli 连接用于调试目的,即使没有它也会发生错误.
I added the extra $mysqli connection for debugging purposes, and the error occurs even without it.
$stmt
可能是 false
.
if ($stmt = $mysqli->prepare(...)) {
$stmt->bind_param(...);
...
}
else {
printf("Errormessage: %s
", $mysqli->error);
}
