Question

我尝试过使用ob_start（）;和exit（）; ，两者都不起作用，请指教，非常感谢

<?php 
    ob_start();

    // connect to the database
    include('connect-db.php');

    // check if the form has been submitted.
    // If it has, start to process the form and save it to the database
    // once saved, redirect back to the view page
    if (isset($_POST["submit"]))
    {
        foreach ($_POST['patientid'] as $index => $patientid)
        {
            $id = mysql_real_escape_string($_POST['id'][$index]);
            $data1 = mysql_real_escape_string($patientid);
            $data2 = mysql_real_escape_string($_POST['vaccineid'][$index]);
            $data3 = mysql_real_escape_string($_POST['vaccinename1'][$index]);
            $data4 = mysql_real_escape_string($_POST['vaccinename2'][$index]);
            $data5 = mysql_real_escape_string($_POST['vaccinename3'][$index]);
            $data6 = mysql_real_escape_string($_POST['totalnoofinjection'][$index]);
            $data7 = mysql_real_escape_string($_POST['nthinjection'][$index]);
            $data8 = mysql_real_escape_string($_POST['date'][$index]);
            $data9 = mysql_real_escape_string($_POST['nextdate'][$index]);
            $data10 = mysql_real_escape_string($_POST['skip'][$index]);
            $data11 = mysql_real_escape_string($_POST['language'][$index]);         

            mysql_query("UPDATE patientvaccinedetail SET patientid = '$data1',
                vaccineid = '$data2', vaccinename1 = '$data3',
                vaccinename2 = '$data4', vaccinename3 = '$data5',
                totalnoofinjection = '$data6', nthinjection = '$data7',
                date = '$data8', nextdate = '$data9', skip = '$data10', 
                language = '$data11'
                WHERE id=$id") or die(mysql_error());

            header("Location: start.php");
            exit;
        }
    }

刚更新，仍然无法重定向到其他页面

Answer 1

您在exit

之后缺少半冒号

更正后的代码：

exit;

Answer 2

在标题调用之前使用ob_end_clean();并使用exit;代替exit

尝试如下

ob_end_clean();
 header("Location: start.php");
exit;

php标题函数不起作用
