用按钮刷新php页面

Question

i have simple coding problem. i have created a page with textbox and share button. the page also contains one Points up button.

i had a problem with that points up button that when the user click on that button and refresh the page ... a window ask for resend of information

for that i have used following code which works fine.

`header('Location: samepageurl.php');

exit;`

but the problem with above code is when user scroll down page and click the button. the page automatically scrolls up. and user have to manually scroll it down.

what i want is the page should refresh but it should be on the same location where it was.

if the problem is still unclear please refer the following images

Answer 1

You can set a fragment identifier.

eg:

<a name="points_up"></a> <!-- this needs to be near that button, the page will scroll exactly where the element is -->

and redirect him to:

header('Location: samepageurl.php#points_up');
die;

Answer 2

Mihai answer is correct, but as you said that fragment identifier is not working because each user has points up button, you can pass user id as a fragment identifier and make a hidden( display : none; ) <a> tag and pass the user id in front of each user...

Like this:

You can set a prefix before a user id too (optional)

<a name="pu12345" style="display: none;"></a>

<?php
   header('Location: whatever.php#pu12345');
   exit;
?>

Answer 3

You can send the request via ajax instead relying on the normal form submission. That will not affect the scrolling of the current page.

Answer 4

Add this line at the bottom of your page before the the <\\body> tag

<button id="PageRefresh">Refresh a Page in jQuery</button>

<script type="text/javascript">
         $('#PageRefresh').click(function() {
         location.reload();
         });
</script>
