(三个不同的数据库,它只是没有插入表中..) 我一直试图将它修复三个小时,如果不是更多的话。也许我只是个白痴,但我看不出有什么不对。
-table name是电子邮件
- 有2行:email varchar(255)和id自动递增

在执行查询时检查变量的名称 你写了$ conn并在初始化连接时使用了$ con

可能会有所帮助的事情:
可变检查!
$con =
mysqli_connect("mysql.hostinger.co.uk",
"u394e","ere31","u159il");
有$con
。其中
$run = mysqli_query($conn, $sql);
有$conn
<强>反引号强>
使用反引号可以使用插入数据库。如下例所示:
$sql = "INSERT INTO emails (`email`)
VALUES ('$email')";
检查您的查询
尝试使用sql_error在查询周围添加if语句,如果它不起作用的话。示例如下:
if(isset($_POST['submit'])) {
$email = $_POST['email'];
$sql = "INSERT INTO emails (email)
VALUES ('$email')";
if ($con->query($sql) === TRUE) {
echo "<script>alert('Uw reactie is toegevoegd.')</script>";
} else {
echo "Error: " . $sql . "<br>" . $con->error;
}
}
希望这有帮助!

您的代码使用了错误的变量 $ conn 时出现错误,请将其替换为$ con,尝试使用此代码。它有效。
<form action="main.php" method="POST">
<input type="email" name="email" placeholder="Enter your email">
<img type="image" id="send" src="bs.png" alt="Submit Form"/>
<button type="sumbit">Submit</button>
</form>
<?php
if(isset($_POST['email'])){
$con = mysqli_connect("mysql.hostinger.co.uk","u1e","1","u1il");
$email = $_POST['email'];
$sql = "INSERT INTO emails (email) VALUES ('$email')";
$run = mysqli_query($con, $sql);
header("Location: result.htm");
}
?>
