losing values.

I have admin.php: It includes the various scripts into the main table layout.

<tr><td><? echo "\n<!-- INCLUDE HEADER START-->\n"; 
include("heading.php"); 
echo "\n<!-- INCLUDE HEADER FINISH-->\n";?></td></tr>
<tr><td><? echo "\n\n<!-- INCLUDE MAIN CONTENT START-->\n\n";
//SEARCH
if (isset($mode)){include("search.php");}

Then I have heading.php: it provides nav links depending on what $vars are set.

if (isset($mode)) //SEARCH
		{
			if ($mode=1)//advanced?
			{
				if (isset($submit))
				{
				$heading="Search Result.";
				$head_nav="<a href=\"admin.php?mode=1\">Search Again</a>";
				}
				else 
				{
				$heading="Advanced Search.";
				$head_nav="<a href=\"admin.php?mode=2\">Simple Search.</a>";
				}
			}
			if ($mode=2)//Simple?
			{
				if (isset($submit))
				{
				$heading="Search Result.";
				$head_nav="<a href=\"admin.php?mode=2\">Search Again</a>";
				}
				else 
				{
				$heading="Simple Search.";
				$head_nav="<a href=\"admin.php?mode=1\">Advanced Search.</a>";
				}
			}
		} //END SEARCH 

And then search.php which initially checks for advanced or simple ($mode1, 2). If I comment out the code in the heading the $mode is there and search.php shows the right content, but with the code in the heading it will only ever recognise $mode as 2, even when it has mode=1 in the calling URL!

Any Ideas?

[packland]

you are setting $mode =2 in the if statement ..

use this

if ($mode==2)//Simple?
(means if $mode equals 2 {})

because what you have means

if ($mode=2)//Simple?
(set $mode =2; if mode exists then{})

understand?

Yeah, Packland is right.

One equal sign means you're assigning a value to that variable

$one = 1;

Two equal signs means is equal to (what you'd want to use to check if $mode [is equal to] 2

if ($mode = 1) // means you're assigning 1 to $mode

if ($mode == '2') // means you're checking to see if $mode equals 2

P.S. Sorry Packland, I posted before you added the full explanation. 😉

😃 Yes I understand, thankyou.
I had it set that way in search.php, but missed it here.
It works 🙂
/me bows.
