building a URL & a db query

[rbragg]

I am building a URL and a SELECT query at the same time. I have a GET method form on search.php. It sends the user to searchResults.php where I am retrieving searchStatus:

 

<?php
if ( !empty($_GET['searchStatus']) ) # if searched
{
  $_SESSION['status'] = mysql_real_escape_string($_GET['searchStatus']); # get selected status from previous page
  $searchStatus = $_SESSION['status'];
  $querySearch.= "AND vigil_call.status_num = '$searchStatus' ";
}
if ( !empty($_GET['refreshStatus']) ) # if refreshed, grab session from URL
{
  $refreshStatus = mysql_real_escape_string($_GET['refreshStatus']);
  $querySearch.= "AND vigil_call.status_num = '$refreshStatus' ";
}
?>

 

If the user is sent from the previous page, then the query is built with the searched status. However, this results page is auto refreshed. On the refresh,  I am trying to display the same results ... just updated. So, I am grabbing the session from the newly built URL.

 

<?php
# build URL
$url = "?lastCall=" . $_SESSION['dbLast'] . "&refreshEagle=" . $_SESSION['eagle'] . "&refreshStatus=" . $_SESSION['status'] . 
"&refreshHall=" . $_SESSION['hall']. "&refreshTech=" . $_SESSION['tech'];
?>

 

I am testing by echoing the values of the 2 variables and it correctly echoes a duplicate number:

 

<?php
echo "status: " . $_SESSION['status'];
echo "<br>refresh status: " . $refreshStatus;
?>

 

The query is successful when first reaching the page and I get my results, but upon refresh the I have no results.  :-\ Can someone be of assistance? Or maybe you know of an easier/cleaner method to achieve the same effect?

Or better yet - why wouldn't this work?

 

<?php
# build URL
$url = "?lastCall=" . $_SESSION['dbLast'] . "&refreshEagle=" . $_SESSION['eagle'] . "&searchStatus=" . $_SESSION['status'] . "&refreshHall=" . $_SESSION['hall']. "&refreshTech=" . $_SESSION['tech'];

if ( !empty($_GET['searchStatus']) )
{
  $_SESSION['status'] = mysql_real_escape_string($_GET['searchStatus']); 
  $searchStatus = $_SESSION['status'];
  $querySearch.= "AND vigil_call.status_num = '$searchStatus' ";
}
?>

 

The session is able to be echoed from the URL but it is still not used in my query.
