Returning Form Error Fields

[David_Wood]

I have a .php form script which is processed by another script - no problem with this it all works.

Within the processing script some data validation takes place and if there are errors the user is returned to the input form along with suitable error messages. Again I have no problems here - this works fine,

What I now want to do is when the errors are returned I want the input form to be populated with the original data - at the moment all of the fields are blank.

Anyone have any ideas on this?

You can store the data in session variables and then populate the fields from the session when you get back to the form...

If you don't want to use session variables, you can submit the form page to itself. Put all the processing script at the top of the page (before you write anything to the browser or you will get a header error (also, see ob_start() )). The processing script can error check--if all is good, hit the db and redirect or whatever, if there are errors, you can display a message and your post/get data is still alive on the page to repopulate your form inputs. There are good posts around on populating drop down menus, radio buttons and check boxes, which are a little bit more involved than setting the value attribute in the text input fields.
