give unique id

[kkshansid]

i hav an online regitration form i m confused about how to give unique id to each student and pass it to printstudent.php so that after filling registration form and after clicking this submit button
printstudent opens which print details

echo "<meta http-equiv='refresh' content='1; url=printstudent.php'>";

@kkshansid
that you have to figure out yourself, but

@kkshansid
this can be done through an URL parameter (though I wonder why you use a HTML redirect instead of calling printstudent.php directly)

i am new to php someone told me form validation occur only when action="" if action="printstudent.php"will form validation occur? what about unique id?

@kkshansid
yes and no. the form’s action attribute is required (you must not leave that out) if you want to submit the form.

validation as is does not require a form per se. it simply means “check if a set of values is valid (conforms to a certain schema)”. though it is obvious that you should validate the user’s input you get (and a form is the standard method to get user input through (a) HTML (page)).

@kkshansid
validation does not depend on a form (validation starts when you tell your script to do so), action="printstudent.php" simple tells the browser, where to send the form data.

@kkshansid
you have to make them somehow. although PHP can help you with the computation, you have to provide the data (it’s like giving a child a name)

Are you using a database of some sort?
