return from header("location:....")

NoBullMan

Hi,
in my php file, I go to a form if a condition is true using header("location:...")
Can I return to the next statement in the php file after submit button is pressed in th form, passing the form values?

if(!isset($_SESSION['cart'])) { // first item to be added to the cart
    header("Location: info_form.php"); // fill out the form
	// get form variables from form's POST
	// ...
	// initialize session variables
  }

Thanx.

Sure, because the condition will be false, right?

It looks good, are you getting an error?

Thanks for the reply guys.
No, I don't get any error messages, just that upon clicking "Submit", nothing happens! Being new to PHP, I was wondering if after clicking the "Submit" button, logically I would be executing the next line of code right after "header("location:infor_form.php")", which would be something like:

if(!isset($_SESSION['cart'])) { // first item to be added to the cart
  header("Location: info_form.php?builder=$builder");
  $_SESSION['cart'] = array();
  // get form variables from POST
  $_SESSION['Name'] = $_POST['Name'];
  $_SSSSION['Email'] = $_POST['Email'];
  etc....

How would you setup the submit button in the form?
Right now, in my form, I have:

<a href="javascript:;" onClick="if (checkForm(document.info_form)) location.href='add_cart.php'; else return false;"><img src="../images/Submit.gif" border="0" /></a>

(the form's name is info_form in the file info_form.php; the php file that uses the form is add_cart.php, and checkForm checks if the required fields are filled out.)

Thanx.

It may be just me but from what I can tell you will never get to the code below the header function:

       if(!isset($_SESSION['cart'])) { // first item to be added to the cart
      header("Location: info_form.php?builder=$builder"); /* This will send you to a new page */
      $_SESSION['cart'] = array(); // sincel the above line sends you away you never get here or below
      // get form variables from POST
      $_SESSION['Name'] = $_POST['Name'];
      $_SSSSION['Email'] = $_POST['Email'];
      etc....

you may want to do the cart check then put another check to see if the page got posted. ie:

 if(!isset($_SESSION['cart'])) 
{ // first item to be added to the cart
      if(!isset($_POST)) // see if post varibale set
      {      

            header("Location: info_form.php?builder=$builder");
      }
      $_SESSION['cart'] = array();
      // get form variables from POST
      $_SESSION['Name'] = $_POST['Name'];
      $_SSSSION['Email'] = $_POST['Email'];
      etc....
}

or something like that. I think that may work.

Ya, buck2bcr is right. I was just looking at your if statement, which looked fine, I guess I should have read the post huh? Anyway, you are getting redirected before the rest of the code is getting processed.

Thanks for the info.
So, if I want to check if there are any arguments sent to a php file, in form of a POST or GET (through file.php?arg1=val1&arg2=val2), I can use:

if(isset($_POST)) 
and
if (isset($_GET))

Thanks.

buck2bcr

I think that you may have to actually do a check on a variable.

if(isset($_POST['Name'])) 
and
if (isset($_GET['Name']))

or whatever one of you form fields names that was populated.

To submit the form, should I use:

 
<a href="java script:;" onClick="if (checkForm(document.info_form)) location.href='add_cart.php'; else return false;"><img src="../images/Submit.gif" border="0" /></a>

or add an action=add-cart.php to the form?

<form name="info_form action="add_cart.php" submit="checkForm">
