如何在执行查询php后重定向

Question

Here is my code:

    $id = $_GET['id'];
$data = $_POST['name'];
$data1 = $_POST['id'];
$c = 0;

foreach ($data1 as $key => $value) {
    $sql = "UPDATE ".$table_comp." SET score = " . $data[$c][$value] . " where id = " . $value .";" ;
    mysqli_query($connect,$sql);
    $c++;
} 
header('Location: http://www.csscorecard.com/admin/?id=$id');

I have problem in my redirect there is an error:

Warning: Cannot modify header information - headers already sent by (output started at /home/csscorecard/public_html/wp-content/themes/twentyseventeen/ajax/submit.php:3) in /home/csscorecard/public_html/wp-content/themes/twentyseventeen/ajax/submit.php on line 54

Answer 1

use javascript instead of headers.

you can use this code to redirect

<?php

echo "<script>window.location.href = 'http://www.csscorecard.com/admin/?id=".$id."'</script>";

?>
