有很多类似的问题,但是我没有任何错误,我需要进行更改。
我在代码中放入了警告框,但没有出现。
这是我的代码-
if(isset($_POST['submit'])){
$test= "select * from stable where Email = '$Email'";
$queryResult = $conn->query($test);
$foundRows = $queryResult->num_rows;
if($foundRows >= 1)
$mailerr="Email already register";
else {
header("location:student.php?id=".$row['id']);
$sql = "INSERT INTO stable
(Firstname,Lastname,DOB,Email,Phno,
Gender,Address,City,ZipCode,State,Country,
Hobbies,Course,id,Time,Date,IP)
VALUES('$Firstname','$Lastname','$Dob','$Email',
'$Phno','$Gender','$Address','$City','$Zipcode',
'$State','$Country','$Hobby','$Course','',
'$Time','$date','$IP')";
if($conn->query($sql))
?>
<script> alert('Data Inserted successfully');
window.location.href='student.php?id=<?php echo $id;?>' </script>
<?php
}
}
最佳答案
您可以将script标签与所有js一起包装在字符串中并回显它。它会工作
if($conn->query($sql)){
echo "<script> alert('Data Inserted successfully')window.location.href='student.php?id="+$id+"</script>";
}
