[PHP Form unwanted refreshing/redirecting]

Thanks for all the help already!

 

I didn't really know a lot about the differences between PHP and Javascript, since most of our classes have been self-study...

 

I'll look into the solutions once I get home from class and see if I can solve my problem!

[PHP Form unwanted refreshing/redirecting]

I have an exercise for school that I have to work out. My teacher is letting us figure it out ourselves, but I've ran into some troubles:

 

- We have to make 2 files: sescook1.php and sescook2.php.

- We have to make a form for the user to fill out their name and favorite color (in sescook1.php).

- We have to check the input (whether there is input or no). If there's isn't any input, we have to echo 'Please fill out __' (in sescook1.php)

- We have to store the name in a session variable and the color in a cookievariable (in sescook1.php)

- If both fields are filled in, we ave to show a link 'go to the next page' (where 'next page' is an URL to sescook2.php).

- All info has to be shown in sescook2.php (Entered name: __, Entered color: ___)

- You have a link 'Go back to previous page' (where 'previous page' is an URL to sescook1.php)

 

My code:

<?php

session_start();

function checkContent() {

if($_POST["name"] == "")

echo "Please enter your name";

elseif($_POST["favcolor"])

echo "Please enter your favorite color";

else

echo "Go to <a href='http://localhost/webadv1011/PHPCookiesSessies/sescook2.php'>next page";

}

?>

 

<form name="color" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>" onsubmit="<?php checkContent(); ?>">

<p>Name: <input type="text" name="naam" /></p>

<p>Favourite color: <input type="text" name="favcolor" /></p>

<p><input type="submit" name="submit" value="send" /></p>

</form>

 

This is the code I got so far. My problem is that the page refreshes itself after it does the checkContent function. I'm also not sure how I save my name in a session variable and the color in a cookie variable (and pass them to the next page as well!).

 

We haven't learned anything on cookies and sessions except our own trial and error and things I found on the internet. Unfortunately, I can't really find lots of useful info (most people refer to Ajax, but we can only use php), or I'm looking in the wrong place.

 

Thanks for your help in advance!
