页面重定向到php中的同一页面

Question

I have two pages let say www.abcd/cont.php and www.abcd/sign.php
When i fill the form in www.abcd/cont.php and click submit , it shows an alert msg and redirect to the same page (ie www.abcd/cont.php) itself .
But instead of redirection, it is going to www.abcd/sign.php page itself.

Here is my sign.php code

if(success){
echo echo '<script language="javascript">';
      echo 'alert("send")';
      echo '</script>';
} else {
 echo '<script language="javascript">';
      echo 'alert("Not send")';
      echo '</script>';
}
header("Location: http://www.abcd/cont.php");
      exit();

i am getting the alert msg but not redirect to that particular page(www.abcd/cont.php) when i click ok on alert message.
Can anyone suggest an idea to do this.

Answer 1

You can just change the URL in JavaScript:

if(success){
    echo '<script language="javascript">alert("send");window.location = "http://www.abcd/cont.php";</script>';
} else {
    echo '<script language="javascript">alert("Not send");</script>';
}

Answer 2

My best guess is that it is happening because you are already sending headers by using the echo function hence your Location() is not working, instead you can try this,

if(success){
echo echo '<script language="javascript">';
      echo 'alert("send")';
      echo 'window.location.href=http://www.abcd/cont.php;';
      echo '</script>';
} else {
 echo '<script language="javascript">';
      echo 'alert("Not send")';
      echo '</script>';
}
