Ok, I tried what you said....Here's the code:
$res = mysql_query(
"SELECT ZG_LATITUDE, ZG_LONGITUDE FROM zip_code where
zg_zipcode = '$zip'");
List($Lat,$Lon) = mysql_fetch_row($res);
$Lat1 = ($Lat-2);
$Lat2= ($Lat+2);
$Lon1= ($Lon-2);
$Lon2= ($Lon+2);
//echo ($Lat1);
//echo ($Lat2);
//echo ($Lon1);
//echo ($Lon2);
$zipcode = mysql_query(
"SELECT * FROM zip_code where ZG_LATITUDE >= $Lat1
and ZG_LATITUDE <= $Lat2 and ZG_LONGITUDE >= $Lon1 and ZG_LONGITUDE <=
$Lon2");
if (!$zipcode) {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
exit();
}
while ( $row = mysql_fetch_array($zipcode) )
{
echo("<b>City: </b>" . $row["ZG_CITY"]. "<br>");
echo("<b>State: </b>" . $row["ZG_STATE"]. "<br>");
echo("<b>Zip Code: </b>" . $row["ZG_ZIPCODE"]. "<br>");
echo("<b>Area Code: </b>" . $row["ZG_AREACODE"]. "<br>");
echo("<b>County FIPS: </b>" . $row["ZG_COUNTY_FIPS"]. "<br>");
echo("<b>County Name: </b>" . $row["ZG_COUNTY_NAME"]. "<br>");
echo("<b>Time Zone: </b>" . $row["ZG_TIME_ZONE"]. "<br>");
echo("<b>Day Light Savings?: </b>" . $row["ZG_DST"]. "<br>");
echo("<b>Latitude: </b>" . $row["ZG_LATITUDE"]. "<br>");
echo("<b>Longitude: </b>" . $row["ZG_LONGITUDE"]. "<P>");
}
I get no results with this still, it acutally doesn't even go to the this
page. When I uncomment out:
//echo ($Lat1);
//echo ($Lat2);
//echo ($Lon1);
//echo ($Lon2);
and comment out everything below this, I get the expected results for
$Lat1,$Lat2,$Lon1, and $Lon2. So I have to believe my issue is below those
lines, can anyone see what I have that is incorrect here?

Hi,
Your problem is that your variables $Lat1,$Lat2,$Lon1,$Lon2 all reffer
to resultsets and not the Latitudes or Longitudes.
Try something like this:
$res = mysql_query(
"SELECT ZG_LATITUDE, ZG-LONGITUDE FROM zip_code where
zg_zipcode = '$zip'");
List($Lat,$Lon) = mysql_fetch_row($res);
$Lat1=Lat-2; $Lat2=Lat+2; $Lon1=Lon-2; $Lon2=Lat+2;
Now you can use the values in your final query.

Emne: PHP and MySql question
Hello, I'm kinda new at PHP programming with MySQL. I am having an
issue and am not sure if this is the corret way to do this: Here is my
code, I'll start there:
<?php
$Lat1 = mysql_query(
"SELECT (ZG_LATITUDE-2) FROM zip_code where zg_zipcode =
'$zip'");
if (!$Lat1) {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
exit();
}
$Lat2 = mysql_query(
"SELECT (ZG_LATITUDE+2) FROM zip_code where zg_zipcode =
'$zip'");
if (!$Lat2) {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
exit();
}
$Lon1 = mysql_query(
"SELECT (ZG_LONGITUDE-2) FROM zip_code where zg_zipcode =
'$zip'");
if (!$Lon1) {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
exit();
}
$Lon2 = mysql_query(
"SELECT (ZG_LONGITUDE+2) FROM zip_code where zg_zipcode =
'$zip'");
if (!$Lon2) {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
exit();
}
$ZipCode = mysql_query(
"SELECT * FROM zip_code where ZG_LATITUDE >= '$Lat1'
and ZG_LATITUDE <= '$Lat2' and ZG_LONGITUDE >= '$Lon1' and ZG_LONGITUDE
<= '$Lon2'");
if (!$Zipcodesearch) {
echo("<P>Error performing query: " .
mysql_error() . "</P>");
exit();
}
while ( $row = mysql_fetch_array($ZipCode) ) {
echo("<b>City: </b>" . $row["ZG_CITY"]. "<br>");
echo("<b>State: </b>" . $row["ZG_STATE"]. "<br>"); echo("<b>Zip Code:
</b>" . $row["ZG_ZIPCODE"]. "<br>"); echo("<b>Area Code: </b>" .
$row["ZG_AREACODE"]. "<br>"); echo("<b>County FIPS: </b>" .
$row["ZG_COUNTY_FIPS"]. "<br>"); echo("<b>County Name: </b>" .
$row["ZG_COUNTY_NAME"]. "<br>"); echo("<b>Time Zone: </b>" .
$row["ZG_TIME_ZONE"]. "<br>"); echo("<b>Day Light Savings?: </b>" .
$row["ZG_DST"]. "<br>");
echo("<b>Latitude: </b>" . $row["ZG_LATITUDE"]. "<br>");
echo("<b>Longitude: </b>" . $row["ZG_LONGITUDE"]. "<P>"); } ?>
Basically I'm trying to have a user input a zip code and then have a php
script pull all zip codes that are in a region of that submitted zip
code.
Can you have a look at my code and see what I'm doing wrong? When using
this it returns no results but makes the connection to the database so I
have to believe that it's within here that I have my issue.
I have Apache/2.0.47 (Win32) PHP/4.3.9 Server and MySql 4.0.14 (I know I
can upgrade and be able to do subselects but I would like to know what
I'm doing wrong here.
Thanks in advance for any help.
Thanks
-rich
