$result = @mysql_query($sql,$connection) or die(mysql_error());

All code files are php.
Any help is appreciated.

$LETTER = $_GET;

should be

$LETTER = $_GET['LETTER'];

P.S. using uppercase for variable names is not preferred by most programmers :)

you are running mysql_query before you set $sql with the query.

wow, that is a lot of uneccessary code. why don't you use one sql query and just input the letter from the get array.

Yeh I already did something similar to that. I changed the if () statement to

if($_GET[LETTER] == "A"){$sql = "SELECT `EndowmentNumber`,`LotSize`,`Letter`,`Section`,`LotNumber`,`LotOwner`,`LastName`,`FirstName`,`MiddleInitial`,`MaidenName`,`Suffix`,`Born`,`Died`,`VeteranInfo`,`MiscInfo` FROM `BurialsTable` WHERE Letter='A' ORDER BY `Letter`, `LastName`, `FirstName`, `FirstName`, `Section`, `LotNumber` ";}

This makes it work.

kkeith29,
Believe t or not the way I reworked this code removed alot of uneccessary code. I am always interested in clening it up more so, how would you reccomend cleaning it up.

nav33n 472 Purple hazed! Team Colleague Featured Poster · Answer 3 · 2008-07-02T19:07:52+00:00

how would you reccomend cleaning it up.

Like this ?

$letter = $_GET['LETTER'];
if(!empty($letter)) {
$sql = "SELECT `EndowmentNumber`,`LotSize`,`Letter`,`Section`, `LotNumber`,`LotOwner`,`LastName`,`FirstName`,`MiddleInitial`, `MaidenName`,`Suffix`,`Born`,`Died`,`VeteranInfo`,`MiscInfo` FROM `BurialsTable` WHERE Letter='".$letter."' ORDER BY `Letter`, `LastName`, `FirstName`, `FirstName`, `Section`, `LotNumber` ";
}

This one query will do exactly what you are trying to do with so many conditions and queries.

Thanks, It works Great. I tried to do this before but couldn't get it to work. That's why I stuck with the if/esleif statements. I see now one problem I had was I forgot the '.'(period) on each side of the $letter statement in the sql query.

Another question I have is: is it possible to have 2 auto submit (document.forms[0].submit();) forms on one page. If so how do I make it work?? I tried once, but the way I had it submitted both forms on the page. The first form, which was empty, took priority resulting in a error - (sql query empty).

Thanks again.

Hey, I seem to have an error in this page (attached file), but I can't seem to find it.
Maybe someone could look over it and find the problem.
I had been getting a unexpected $end error.
I got that resolved, but now I get a 'query was empty' error.
I double checked and I think I got it the same way as was listed above.
Of course any reccomendations are appreciated.
The config/db2.pp is simply the sql connect info.

The code fil is attached.

sel_Town.php_.txt (1.79 KB)

<?php

include ('./config/db2.php');

//make connection to dbase
	$connection = @mysql_connect($server, $dbusername, $dbpassword)
				or die(mysql_error());
	$db = @mysql_select_db($db_name,$connection)
				or die(mysql_error());

$result = @mysql_query($sql,$connection) or die(mysql_error());

$town = $_GET['TOWN'];
if(!empty($town)) {$sql = "SELECT `Town`, `Cemetery` FROM `BurialsTable` WHERE Town='".$town."' ORDER BY `Cemetery` ";}

while ($row = mysql_fetch_array($result)) {
if (!$row["Cemetery"]) { $Cemetery=""; 
} else { $Cemetery = "<option value=\" ".$row['Cemetery']." \"> ".$row['Cemetery']."</option>";}

if (!$row["Town"]) { $Town=","; } else { $Town = "<strong>".$row['Town'].",</strong>"; }


$display_block .= "$Cemetery"; }

I knew whatever it was would be simple. Makes me feel dumb not catching that. Thanks a Lot
