global variables

kraftwerk

i have a php variable that was created through an input text box

ex:
<b>Name: </b><input type="text" name="name"><br>

i'm making a multi-page thing. i want the $name variable to be global, but its not working. on the next page, i create a txt file based on the $name variable and then store data into that txt file. like this:
$file=fopen("$name.txt",'a');
fwrite($file,$picks);
fclose($file);

it works only for that page. when i go on to the next page(s), it stores everything into ".txt" instead of "$name.txt". so i assume that this is b/c $name is not global. how do i fix this?

Ok first off, do you know if register_globals is 'on' for your site / host? If not, then the value stored in $name will not track from one script to the next. You have to use either $POST['name'] or $GET['name'] depending on which method you use in your form.
Another issue may be how the script that handles the form data is using those vars. Something you may want to try is temporarily editing your script to just print out the value stored in $name to see if it even makes it over, then work out from there.

i'm using a POST method on my form. so should i just do this:

$file=fopen("$_POST['name'].txt",'a');
fwrite($file,$picks);
fclose($file);

will that work?

Right. Or you could just define $name beforehand like this:

$name = $_POST['name'];

I don't know for certain that that's your problem, but try that out and see if it works.
