Passing Variables Between Scripts

[Anon]

Hello,

I have a quick and probably stupid question.
I'm using a set of PHP scripts and I want to pass some variables between them. For example, let's set a variable called $name to 'Mike'. Now at the bottom of the page that this script generated, I want to have a submit button, and when I click submit, I want it to run a new .php script and pass it the value in $name. How would I go about doing this?

Thanks!
Mike

Hi Mike!

First, you are going to be very happy to realize how easy this is. Okay, forms :

http://htmlgoodies.earthweb.com/tutors/forms.html

As you go through the form tutorial above (or any other you choose) pay special attential to NAME and VALUE. Here is what it means :

name=value
variablename=itsvalue

And in the url :

index.php?name=value&anothername=value

Now, to use this create two pages. Put your form in the first page. For now, make all your forms the GET method and look at the urls. So :

---index.php-----

<form method="get" action="process.php">

<br><input type="text" name="foo">
<br><input type="text" name="blah">
<br><input type="submit" name="submit">
</form>

---

---process.php----

<?php

print "$foo and $blah";

?>

WOW, pretty easy huh? Whatever you typed in index.php will print out. Add more , experiment with different types and most of all, have fun :-)

If it's a form, you can include a hidden field with that name and value.

<FORM method="POST" action="next.php">
<INPUT type="hidden" name="name" value="<?php echo $name; ?>">
<INPUT type="submit" value="Submit">
</FORM>

Now next.php will have access to $name.

Or just add the variable to the URL at the point you redirect to the next script, e.g. if in an anchor tag;

<a href="next.php?name=<?php echo $name; ?>";
