Preserve $_POST variables for multiple reloading of page............

Question

I have some datas that are submitted with POST method on the same page. I have some actions and layout which follow up using these datas. Among those actions, I also have a quick action which sends the parameter in query string. When I click on this link, I can fetch the action that I am trying to do, but I loose all the variables from my POST, which I need to display the same page again.

Is there a way, that I can preserve POST variables, for multiple reloading times.

Answer 1

You can try saving that data in a session instead ?

Answer 2

You'll need to parse the data in $_POST and recreate it in your form. You can do it with hidden fields.

Or, you can save the $_POST data in a user session and refer to it when you need it. You'll have to manage the lifecycle of the data to make sure it doesn't stay around too long.

Answer 3

The problem is that you are sending the data in via the URL which is stored in the $_GET variable, not in $_POST. If you want the ability to submit the data in either format, use $_REQUEST instead.

There is a bit of a debate on whether it is a good idea to use $_REQUEST, but if you are doing a simple site, there is little wrong with it.

If you would rather not use $_REQUEST, then you can use the following code on each variable you are expecting:

if (!empty($_GET['foo'])) {
    $foo = $_GET['foo'];
} elseif (!empty($_POST['foo'])) {
    $foo = $_POST['foo'];
} else {
    die("Foo not submitted");
}

Answer 4

I would suggest not using $_POST but using $_REQUEST. This means you can format your links thus, which will preserve all of the data in $_REQUEST:

function addParams($link){
  $result = $link;
  $first = true;
  foreach($_REQUEST as $key=>$value){
    $link .= ($first) ? '?' : '&';
    $first = false;
    $link .= "$key=$value";
    }
  return $link;
  }

...

echo "<a href='".addParams('nextpage.php')."'>Next Page</a>";

However I don't condone this method, you should use $_SESSION!
