Hi guys,

I am trying to pass variables through my pages it can be asp or php, I have managed to pass "fname" to the next page but I would like page2 which retrieves this information to store it in a hidden field so that I can pass it to another page, any ideas on how to do this?

Thanks guys

If it's in a form, that's easy. So for example our original link which leads from page 1 to page 2 might be:

http://www.yoursite.com/page1.php?name=Joe

Then on page 2 you simply add this to your HTML form:

<input type="hidden" name="name" value="<?php echo $name; ?>">

:) :yes

Just off the cuff, I think a 'global function' should be able to handle that.

Once again, Corey is quick on the fly. He mentioned that you were "talking web pages". That's what I get for reading/replying too quick. I was thinking too deep. Need more java I guess.

Hi again,

I seem to be having a little trouble with this one.

I can post to the first page which is called welcome.php but I cannot seem to post to welcome2.php as I have an error on line 5

I cannot seem to work it out.

<html>
<body>Welcome <?php echo $_POST["name"]; ?>.<br />
</body>
<form action="welcome2.php" method="POST">
<input type="hidden" name="name" value="<?php echo $name; ?>">
<input type="submit" />
</form>

</html>

Any more help will be greatly appreciated.

Thanks :huh

Hi. In that case just use:

<input type="hidden" name="name" value="<?php echo $_POST["name"]; ?>">

:yes :)

Hi again guys,

I just have a little question about php and storing everything globally

I have used a include function on evey page and I am wondering if I enter my name and then retrieve it on page 3, then on page 4 if I have another input box which uses the var name "name" again wil it overwrite the stored var?

Thanks guys, and Ron thanks for your suggestion on globals it does keep everything nice and tidy and it is easier to learn with. :yes

Yes it will, you can only use each variable name once if you wish the value to hold, or at least you would have to shift the value to another variable/array if you want to keep it but re-use the variable name. :)

It's the same as in AMS if you replace a variable value, the first one is lost, i.e.:

name = "Joe";
name = "Bob";

Will result in the variable called "name" containing the value "Bob". "Joe" is lost forever unless you shift it somewhere else, i.e.

names={};
name = "Joe";
names[1] = name;
name = "Bob";
names[2] = name;

Would result in the variable "name" containing the value "Bob" but the table "names" containing both "Joe" and "Bob"... Hope that helps. :)
