Redirecting value in same page

Question

lets say, I am sending a question number from page a.php to page b.php.

<a href=../home/Open.php?var=$row[id]></a>

After receiving the question number in b.php at

$var=$_GET['var'];  

now the problem is I want to redirect the same page b.php using header

header("Location:open.php?var=".$var);

and passing the same value that I received from a.php.

Now is it possible to receive the value at

$var=$_GET['var'];  

again?

Answer 1

Your var is empty because you use your PHP value wrong.

• There is no quote around id - if id is not a variable.

• No echo

• No <?php ?> around it.

Should be:

<a href="../home/Open.php?var=<?php echo $row['id']; ?>"></a>
