这是我的php文件... 我想在第二个表成功插入后更新第一个表,我要正确选择和插入,但是在插入数据后我想要更新的行没有得到更新。
if($_SERVER['REQUEST_METHOD']=='POST')
{
$full_name=$_POST['full_name'];
$email_address=$_POST['email_address'];
$contact_number=$_POST['contact_number'];
$gender=$_POST['gender'];
$location=$_POST['location'];
$standard=$_POST['standard'];
$institute=$_POST['institute'];
$code=$_POST['code'];
$sql = "SELECT * FROM activations WHERE code='$code' AND status='not used'";
$check = mysqli_fetch_array(mysqli_query($conn,$sql));
if(isset($check)==null)
{
echo 'exist';
}
else
{
$sql1="INSERT INTO students(full_name, email_address, contact_number, gender, location, standard, institute) VALUES('$full_name','$email_address','$contact_number','$gender','$location','$standard','$institute')";
}
if (mysqli_query($conn, $sql1)==true)
{
$sql2="UPDATE activations SET status='in use' WHERE code='$code';
} else {
echo "Error updating record: " . mysqli_error($conn);
}
任何人都可以告诉我如何用php mysqli程序方式写这个。
答案 0 :(得分:0)
您忘了致电mysqli_query()
来执行UPDATE
。
if (mysqli_query($conn, $sql1)) {
$sql2="UPDATE activations SET status='in use' WHERE code='$code'";
if (!mysqli_query($conn, $sql2)) {
echo "Error updating activations: " . mysqli_error($conn);
}
} else {
echo "Error inserting student: " . mysqli_error($conn);
}
