[SOLVED] if (isset) not working


whiskedaway

Recommended Posts

I think I've made a silly mistake somewhere, but I can't find it, so any help would be appreciated! I've used if (isset) in other parts of my website and it works fine, but I can't get it working here.

 

Basically, the PHP is meant to run a query on my database and return $staffID, $name, $address and $phone, and then is meant to be displayed in a table that is located in stafflook.inc.

 

Code snippets:

$cxn = mysqli_connect($host, $user, $password, $dbname) 
               or die ("Connection failed.");

    $sql = "SELECT staffID, name, address, phone FROM Staff
	       WHERE staffID = '$_POST[staffID]'";	
    $result = mysqli_query($cxn, $sql)
                  or die ("Couldn't execute query.");
        $rowname = mysqli_fetch_assoc($result);
        extract ($rowname);

	$echoName = "<tr><td><strong>ID:</strong></td><td>$name</td></tr>";
	$echoID = "<tr><td><strong>ID:</strong></td><td>$staffID</td></tr>";
	$echoAddress = "<tr><td><strong>ID:</strong></td><td>$address</td></tr>";
	$echoPhone = "<tr><td><strong>ID:</strong></td><td>$phone</td></tr>";

	include("stafflook.inc");

 

stafflook.inc:

<table width="250" border="0" align="center" cellpadding="2" cellspacing="2">
<?php
    if (isset($echoID)) { echo "$echoID";}
if (isset($echoName)) { echo "$echoName";}
if (isset($echoAddress)) { echo "$echoAddress";}
if (isset($echoPhone)) { echo "$echoPhone";}
?>
</table>

 

If someone can see where I've made a mistake, it'd be greatly appreciated.

I'm actually getting no output at all, even with putting print_r($array);. I would assume that opening the page I'd get no output, but when I run the query, it should work.

 

Here's the full code for both of the pages, hopefully it might be something that's not in the first code snippets:

<?php

    session_start();

    if (@$_SESSION['auth'] != "yes") {

        header("Location: management.php");
        exit();
    }
	include("credentials.inc");

switch (@$_POST['do']) {

    case "search":

    $cxn = mysqli_connect($host, $user, $password, $dbname) 
               or die ("Connection failed.");

    $sql = "SELECT staffID, name, address, phone FROM Staff
	       WHERE staffID = '$_POST[staffID]'";	
    $result = mysqli_query($cxn, $sql)
                  or die ("Couldn't execute query.");
        $rowname = mysqli_fetch_assoc($result);
        extract ($rowname);

	$echoName = "<tr><td><strong>Name:</strong></td><td>$name</td></tr>";
	$echoID = "<tr><td><strong>ID:</strong></td><td>$staffID</td></tr>";
	$echoAddress = "<tr><td><strong>Address:</strong></td><td>$address</td></tr>";
	$echoPhone = "<tr><td><strong>Phone:</strong></td><td>$phone</td></tr>";

	print_r($array);

	include("stafflook.inc");

        break;

        default:

        include("stafflook.inc");

}
?>
