单击提交按钮重定向到index.php

Question

here's my code.

if(isset($_POST['add']))
{
  $_POST['os_number'];
  $_POST['product'];
  $_POST['quantity'];
  header('location:index.php?page=pos');
}

this code belongs to pos.php and link (pos/index.php?page=pos) but when I click the submit button it redirects to index.php with this link (pos/index.php?os_number=1001&product=1&quantity=&add=ADD) I wonder why. I need your help guys. it should remain in pos/index.php?page=pos link.

Answer 1

If you want to post your forms to index.php you can erase your code and use this on your html. This will redirect you to index.php?page=pos when click submit

<form action="index.php?page=pos" method="post">
    <input type = "text"    name = "os_number"/> 
    <input type = "text"    name = "product"/> 
    <input type = "text"    name = "quantity"/> 
    <input type = "submit"  name = "add" value = "ADD" /> 
</form>

and better you can just put page=pos on a hidden input

<input type = "hidden"  name = "page" value = "pos"/> 

Hope this help

Use exit after header('location:index.php?page=pos'); line.
