PHP Help with Form Submit
Hi,
I have a custom HTML form that has a couple radio buttons and a text field that requires a number.
I'm not a php programmer and could use some help with putting together php code to calculate a total based on the radio button selection and the text field number.
-------------------------------
Here is a snippet from the form:
<input value="$1.20 standard design" class="radio radio radio" id="$1.20 standard design" name="radio2" type="radio" />
<label for="$1.20/standard_design" class="radio_label">$1.20/standard_design</label>
<input value="$2.10 extended_design" class="radio radio radio" id="$1.20 standard design" name="radio2" type="radio" />
<label for="$2.10/extended_design" class="radio_label">$2.10/extended_design</label>
<div class="form_element cf_textbox">
<label class="cf_label">Quantity to order? *</label>
<input class="cf_inputbox required validate-number" maxlength="150" size="30" id="text_27" name="text_27" type="text" />
</div>
-------------------------------
I need PHP code to take one of the Radio button values and then multiply it by the Quantity, then from the the discount table apply the appropriate discount and save the total in a variable.
Quantity Discount table is:
50-99 10% Off 400-799 40% Off
100-199 20% Off 800-1999 50% Off
200-399 30% Off 2000-4999 60% Off
I appreciate any help with this.
Thanks

LEARN ABOUT PHP
sqlsrv_begin_transaction
SQLSRV_BEGIN_TRANSACTION(3) SQLSRV_BEGIN_TRANSACTION(3)
sqlsrv_begin_transaction - Begins a database transaction
SYNOPSIS
bool sqlsrv_begin_transaction (resource $conn)
DESCRIPTION
The transaction begun by sqlsrv_begin_transaction(3) includes all statements that were executed after the call to sqlsrv_begin_transac-
tion(3) and before calls to sqlsrv_rollback(3) or sqlsrv_commit(3). Explicit transactions should be started and committed or rolled back
using these functions instead of executing SQL statements that begin and committ/roll back transactions. For more information, see SQLSRV
Transactions.
PARAMETERS
o $conn
- The connection resource returned by a call to sqlsrv_connect(3).
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
sqlsrv_begin_transaction(3) example
The following example demonstrates how to use sqlsrv_begin_transaction(3) together with sqlsrv_commit(3) and sqlsrv_rollback(3).
<?php
$serverName = "serverNamesqlexpress";
$connectionInfo = array( "Database"=>"dbName", "UID"=>"userName", "PWD"=>"password");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn === false ) {
die( print_r( sqlsrv_errors(), true ));
}
/* Begin the transaction. */
if ( sqlsrv_begin_transaction( $conn ) === false ) {
die( print_r( sqlsrv_errors(), true ));
}
/* Initialize parameter values. */
$orderId = 1; $qty = 10; $productId = 100;
/* Set up and execute the first query. */
$sql1 = "INSERT INTO OrdersTable (ID, Quantity, ProductID)
VALUES (?, ?, ?)";
$params1 = array( $orderId, $qty, $productId );
$stmt1 = sqlsrv_query( $conn, $sql1, $params1 );
/* Set up and execute the second query. */
$sql2 = "UPDATE InventoryTable
SET Quantity = (Quantity - ?)
WHERE ProductID = ?";
$params2 = array($qty, $productId);
$stmt2 = sqlsrv_query( $conn, $sql2, $params2 );
/* If both queries were successful, commit the transaction. */
/* Otherwise, rollback the transaction. */
if( $stmt1 && $stmt2 ) {
sqlsrv_commit( $conn );
echo "Transaction committed.<br />";
} else {
sqlsrv_rollback( $conn );
echo "Transaction rolled back.<br />";
}
?>
The above example will output something similar to:
