Keeping FORM variables

DennisMV

Hey,

Suppose you enter values in a form, and then press Submit.
I want the browser to go to the next page, and just display all the FORM data, with a message at the bottom, like "Are You Sure you want to add this to the database ? "

So, then, if you click YES, it would add the data to the database.
If no, then just go back.

I know that in Java you can do this using JavaBeans.

But in PHP I'm not sure how to do this. I'm feel there are several different ways to do this, but it there a better way ?

thanks !

There are several ways - whether there is a better one depends on which one it's supposed to be better than.

The simplest would be to have on the confirmation page a bunch of hidden fields in the form that contains the confirmation button, which would submit all those hidden fields to the script which puts them in the database.

That makes for a silly amount of back-and-forth of form data, though. Using session variables would mean that the form data can remain on the server for later retrieval by the database insertion script or the original form (depending on whether the user confirms or vetoes the submission).

Is ther a way to use an object and put all the variables there ?
Can this be done using session object ?

If that's possible, it will be a better way in terms of less code and therefore less work.

I'd rather have less code, that way I think it'll be easier to maintain and to understand.

I just found something advocating NOT to use session variables... expecially for objects, since that hurts performance.
Also, I remember somewhere that you can't store objects in session variables in PHP.

humm... but what about user tracking ? I think sessions are just the best for that.

I'm still wondering how to keep passing all the parameters from one page to another. There are about 30 different parameters in total. Having hidden forms is one way, but it's somewhat cumbersome. If there is a simpler way, I'd rather go for that.

thanks,
Dennis

You can create an array made up of the variables then

for($i=0;$i=sizeof($array);$i++) {
<input type="hidden" name="name[]" value="$array[$i]">
}
<input type="submit" value="Submit">

This way you get to pass all the variables without all the hidden form elements

However the easiest way to manage this sort of thing is to make sure your form field names make up the elements in an array to begin with.

For instance give all your form fields the same name;

formfield[0],formfield[1]......

Then when the you get the form elements on the next page you have everything you need without a bunch of code to deal with
