So currently I have 2 files that pretty much does the same thing but connects to 2 different tables. I sort of want to merge it together to save file space and make everything more efficient:
caseprice.php
<?php
$q = intval($_GET['q']);
$con = mysqli_connect('localhost','root','','test');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
mysqli_select_db($con,"compcase");
$sql="SELECT * FROM compcase WHERE id = '".$q."'";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['case_price'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
caselightprice.php
<?php
$q = intval($_GET['q']);
$con = mysqli_connect('localhost','root','','test');
if (!$con) {
die('Could not connect: ' . mysqli_error($con));
}
mysqli_select_db($con,"complight");
$sql="SELECT * FROM complight WHERE id = '".$q."'";
$result = mysqli_query($con,$sql);
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['caselight_price'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
also how can I use all this to display a sub total on my page when the radio buttons are pressed? I have it so the price shows I just cant seem to add them both up:
index.php
<script>
//CASE PRICE//
function casePrice(str) {
if (str=="") {
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else { // code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200) {
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","caseprice.php?q="+str,true);
xmlhttp.send();
}
//CASE PRICE//
//CASE LIGHT PRICE//
function caselightPrice(str) {
if (str=="") {
document.getElementById("txtHint").innerHTML="";
return;
}
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else { // code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200) {
document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","caselightprice.php?q="+str,true);
xmlhttp.send();
}
//CASE LIGHT PRICE//
</script>

<div id="txtHint"><b>Processor listed here</b></div>
<div id="txtTest"><b>Processor listed here</b></div>
as you can see, the price is displaying separately. Can I somehow calculate it as a subtotal instead of separate totals?
Thanks for any help.
