Reload a page and redirect?

[gyzhao]

I am developing website for user to submit a form online. I have insertAction page1 that serves for this need. When a user fills the stuffs on insertAction1 and hit submit button, it then calls inserAction2 page to display the data. In the meantime, the data go into the backend database.

Here is my problem, however, if the user reloads or refreshes the browser while he is at insertAction page2. All the insert data will be duplicated. Is there any way in ColdFusion or JavaScript to avoid that or redirect to the update page? If so, how? Do you have any existing code that I can use?

Thanks for your help.

i think the standard way of doing it is sufficient for your purposes. First, let the form do a post to the action page. Second, wrap the code in the action page around a construction similar to <cfif isDefined("form.aFormField")></cfif> . You should therefore end up with something like

insertAction1.cfm
===============
<form action="insertAction2.cfm" method="post">

insertAction2.cfm
===============
<cfif isDefined("form.aFormField")>
<!--- data validation, business code such as inserting data, etc.--->
</cfif>

Then the only way to insert data is to submit a form to insertAction2.cfm.

BKBK, Peter,

using <cflocaion> does solve my problem. Thank you all so much!

I always redirect the user to another page after the action page is finished inserting or updating information. Usually I just go back to the original form page, this way the user can see that the information was updated. You can also put a message on this page saying that the information was submitted, deleted, updated, etc.

use <cflocation url="page1.cfm">
