How to use arrays for form input and update respective database records

I'm new to PHP... I want to know how to populate a form from mySQL. I'm stumped at the input section where I am trying to allow the user to select choices for radio button /checkbox for each record. thanks in advance for anyone's help!

Here's a snippet of my code:

<?php

$mQuantity = 1;

$con = mysql_connect("localhost","t","c");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("tc", $con);

/*
    if request.form("itemname")<>" " then
        cSQLAcct =  "SELECT * FROM Restaurant_Menus WHERE Restaurant_ID='" & mRestaurant_ID & "' and Item like '%" & Request.Form("ITEMNAME") & "%'  ORDER BY FOODTYPE, ITEM"
    else
        cSQLAcct =  "SELECT * FROM Restaurant_Menus WHERE Restaurant_ID='" & mRestaurant_ID & "' ORDER BY FOODTYPE, ITEM"
    end if
*/

// retrieve form data 
$input = $_POST['itemname'];
echo $_POST['ITEM'];
$mItem = $_POST['ITEM'];
$mPrice = $_POST['PRICE'];
$mQuantity = $_POST['QUANTITY'];
$mOrderTotal = 0;
$mSide0 = '1';
$mOil = '1';
$mStarch = '1';
$mSalt = '1';

// use it 
echo "You searched for: <i>$input</i>"; 
echo $mSessionID;

mysql_query("INSERT INTO OrderQueue (SessionID,item,quantity,price,no_oil,no_starch,no_salt,side0) VALUES ('$mSessionID','$mItem','$mQuantity','$mPrice','$mOil','$mStarch','$mSalt','$mSide0')");

/*
$sql="SELECT * FROM Restaurant_Menus
WHERE
Item like '%$input%'";
*/


$sql="SEL开发者_运维问答ECT * FROM OrderQueue
WHERE
SessionID = '$mSessionID'";

$result = mysql_query($sql); 

//('$_POST[firstname]','$_POST[lastname]','$_POST[age]')";

//echo $input;
//echo $sql;

/*
if ($input!=" "){
    $result = mysql_query($sql); 
    }

//          cSQLAcct =  "SELECT * FROM Restaurant_Menus WHERE Restaurant_ID='" & mRestaurant_ID & "' and Item like '%" & Request.Form("ITEMNAME") & "%'  ORDER BY 
else
{   $result = mysql_query("SELECT * FROM Restaurant_Menus");
}
*/

$class[1] = 'odd';

You should name your HTML form elements as such: MyElement[] when using them as arrays. For example:

<form method="post" name="myForm" action="myForm.php">
    <select multiple name="myFormSelectMultiple[]">
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
    </select>
</form>

In this select multiple example, when the first two items are selected and then posted this form would produce similar output to the following:

array('myFormSelectMultiple' => array(1,2)); 

Hope this helps!
