我无法让它工作。我遇到了障碍。请有人看一下，如果您发现我遗漏的内容，请告诉我。已验证与 mysql 的连接正常工作。当我提交表单时，它会显示“记录插入成功”。但数据库中没有创建实际记录。我尝试过不同的方法但没有成功
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST"){
$usrID = $_POST["usrID"];
$Fname = $_POST["Fname"];
$Lname = $_POST["Lname"];
$short_title = $_POST["short_title"];
$email = $_POST["email"];
$phone = $_POST["phone"];
$link = mysqli_connect("localhost", "username", "topsecret", "DBname");
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
$sql = "INSERT INTO tableName (usrID, Fname, Lname, short_title, email, phone) VALUES (?, ?, ?, ?, ?, ?)";
if($stmt = mysqli_prepare($link, $sql)){
mysqli_stmt_bind_param($stmt, "sss", $usrID, $Fname, $Lname, $short_title, $email, $phone);
mysqli_stmt_execute($stmt);
echo "Record inserted successfully.";
} else{
echo "ERROR: Could not prepare query: $sql. " . mysqli_error($link);
}
mysqli_stmt_close($stmt);
mysqli_close($link);
}
?>

最佳答案
看起来这个声明返回 true:
if($stmt = mysqli_prepare($link, $sql)){
无论执行的语句返回什么，如果上述语句为 true，它都会打印您的行:
mysqli_stmt_execute($stmt);
echo "Record inserted successfully.";
$stmt 中的语句是什么？检查sql并验证其是否正确。
