Saving value after a refresh

I'm passing a value 'name="idUser"' through a Form with POST from pageA to pageB.

Then in pageB I have a query that uses this value for different things, like select, updates, inserts,etc.

Ej: $updateIDU=$_POST["idUser"];

Select * from table where idUser = $updateIDU;

The pageB has a table in a Form that it can be updated (you can add values, with the form you send the values to the database).

After the information is updated to the database i refresh the page with this:

$link="LOCATION:pageB.php?ok=1";
header($link);

The problem is when i refresh the page with that method the querys for the tables crashes with errors:

Notice: Undefined index: idUser in C:\wamp64\www\pageB.php

Can somebody help me fix my problem or is there another way to pass this value (ID) from pageA to pageB without losing it on refresh (updating the form-table)?

Note When I refresh the page (F5) the page dosen't show me any errors, but when I update the table (with the form) it does show me the error.

Instead of using Post you can set a cookie to retain data across all the pages. Set cookie using this:

setcookie("TestCookie", $value);

And then access them using this:

$_COOKIE["TestCookie"];
