| 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
