我知道这看起来像是一个重复的问题。看过不同的问题和答案，但很难得到结果。所以基本上我的编辑配置文件工作得很好，在我决定有更多的字段和仍然字段以某种方式导致问题。所以我得到了这个错误
致命错误：在布尔值上调用成员函数bind_param（）。
我将向您展示我的 php代码

当我拿出$postcode字段时，我刚刚添加它时会发生什么通知它运行正常，这让我感到困惑的是问题所在。至于提到勒勒已经通过以前的问题，并回答没有运气。
答案 0 :(得分：-1)
你的问题在这里：
if(!($stmt = $con->prepare("UPDATE user SET firstname = ?, lastname = ?, profession = ?, user_name = ?, phone = ?, address = ?, email = ?, bio = ?,
gender = ?, postcode = ?, dob = ?, country = ? WHERE id = ?"))) {
echo "Prepare failed: (" . $con->errno . ")" . $con->error;
}
if(!$stmt->bind_param('ssssissssssi', $firstname, $lastname, $profession, $user_name, $phone, $postcode, $address, $email, $bio, $gender, $dob, $country, $userId)){
echo "Binding paramaters failed:(" . $stmt->errno . ")" . $stmt->error;
}
您在$ con＆gt; prepare（）
中放置了一个带有$ postcode的绑定参数，但没有将postcode =？替换为：
if(!($stmt = $con->prepare("UPDATE user SET firstname = ?, lastname = ?, profession = ?, user_name = ?, phone = ?, postcode = ?, address = ?, email = ?, bio = ?,
gender = ?, postcode = ?, dob = ?, country = ? WHERE id = ?"))) {
echo "Prepare failed: (" . $con->errno . ")" . $con->error;
}
if(!$stmt->bind_param('ssssissssssi', $firstname, $lastname, $profession, $user_name, $phone, $postcode, $address, $email, $bio, $gender, $dob, $country, $userId)){
echo "Binding paramaters failed:(" . $stmt->errno . ")" . $stmt->error;
}
