Preventing Double Orders

This small bit of JavaScript can prevent orders from being submitted twice.

The key is that instead of a standard "submit" button (<input type="submit"...>), we use a regular button (<input type="button"...>) that calls the "submit()" function using JavaScript.

This part goes in the head:

<SCRIPT language="JavaScript">
var submitted = false;

function doSubmit(form) {
if (!submitted) {
submitted = true;
// -->

And this is the generic button and function call:

<INPUT TYPE="BUTTON" VALUE="Click To Accept" NAME="submission" ONCLICK="doSubmit(this.form)">
