Returning to Form

drag0n

Hi:

I was wondering if I could get some input/opinions about what would be the best way to return a user to a form on another page because they entered in wrong info or left fields blank?
I am already using Jscript to "precheck" the form before actually submitting it; but people could cheat that or if there are other reasons I need them to redo the form then what can I do?
I am currenting using the history(-1) function basically same as the back button and storing the values in sessions to keep them on the form.
Any other way to do this better and more efficently? Because in some areas I am using ajax pop-out model boxes to display forms and whatnot; if I do a back button then the whole page goes back and everything is lost.
What are you guys currently using to do this?

Thanks

hello,

its an example:

http://www.phpcode.hu/example.txt

add.php: it is a form to collect the info from the user,

added.php is the insert program.

in added.php i store the posted data in $_SESSION["content_filedname"] , and there is a check for required values. And that's name stored a session variable, to make the missed form elements into red background.

in added.php you can write a session delete, when a succesfully inserted happened.

i cant access the link u gave me... would you mind posting the code please?
also; i have a question about classes maybe you can help me answer.
In a class I have I am returning boolean values in a function. everything works but when I try to use an if state to test the value of the return like this:
if($user->isLoggedIn() = FALSE) { //whatever }
I get an error saying "Can't use method return value in write context"; but when I test to see if the value is NOT true; then it works perfect. what is wrong with my function? I am just either using return TRUE; or return FALSE;.

Thanks

if that is the problem you don't use double = sign in the IF clause.

I have not start to learn more about this OOP topic.

Here is the example:

i thought you only use double = sign for values; and one equal sign for boolean.
what would u recommend as a good tutorial for me to read on? i already know java so thats why im using php oop.

One equals sign for assignment, two for testing values, the same as

java

except that PHP also has === for testing values and types.

When comparing objects, $obj1==$obj2 looks to see if the two objects have the same properties and the same values, $obj1===$obj2 looks to see if they are references to the same object.

So; does anybody have any ideas about returning user to previous page while using ajax? Such as css popup models and such?

You don't need to use submit to send the user, the entered data is wrong, is already in the database, not a number or contains special chars.

check if the user change a form element, and send those variables to a php useing ajax. And then you could use a javascript popup to tell the visitor if its values are wrong. The Submit button was generated with javascript and disabled while the user gives wrong data.
