<INPUT TYPE="image" NAME="submit_two" SRC="b2.gif">
//Properly determining which submission button was clicked in PHP:
<?php
if(isset($_GET["submit_one_x"])) {
} elseif(isset($_GET["submit_two_x"])) {
} else {
}
?>

Using Arrays with Form Data in PHP
<SELECT NAME="myselect[]" MULTIPLE SIZE=3>
<OPTION VALUE="value1">A</OPTION>
<OPTION VALUE="value2">B</OPTION>
<OPTION VALUE="value3">C</OPTION>
<OPTION VALUE="value4">D</OPTION>
</SELECT>
//The PHP code to access which value(s) were selected:
<?php
foreach($_GET["myselect"] as $val) {
echo "You selected: $val<BR>";
}
echo "You selected ".count($_GET["myselect"])." Values.";
?>
