Conditional Post to another php page

[Deepzone]

Hi there,

 

I use ACTION="xxx.php" in form tag to move to another page. Is it possible, in php, for me to remain on the same page if error occur else then post to xxx.php page? Thanks.

With strictly PHP I do not believe this to be possible since the form handler would need to process the form before determining if any errors occurred.

A better approach would be to handle both the form and any errors that occur on the landing page.

Uhmm... yes. Validate your form with Javascript/jQuery then submit the form (submit()) to the desired page if no error(s) was found.

Javascript validation is not reliable. The user may choose to turn off Javascript.

 

The best approach (IMO) is to post to the same page and process the data. If an error occurs, you can show the form, with the user's supplied data so they don't have to re-type everything, just the invalid stuff.

 

If there are no errors you can use PHP to redirect to the final page:

header('Location: http://www.mydomain.com/thankyou.php');
exit();
