using variables from form

[Phi]

Hi there,

I've just started learning php and I hope you guys could help me with
this problem. I've found a useful pice of code from a book to make a form
and I would like to use it. I would like to print the variables (input)
on the screen , but I can't make it work. I think I have to do something
with an array, but don't know what. I've tried

$field = $_POST['field'];
echo $field;

and also

$arr = $_POST['array'];
print_r($arr);

but it doesn't work.

Could some one show me what I'm missing?

Thanks a bunch!

try to make a phpinfo(); on the page you submit to and see if the
variables are there (almost at the bottom).

I don't know if it's this what you mean. Thanks for your time again...

1. you forgot to pass "post" to your function:

print_form("aut oform2.php", "post", "field", "field2", "field3",
"field4");

would work with your script.

2. the result from func_get_args() is an array, you you have to change

echo "$i <input type = text name =". func_get_args($ i) . ">

to this:

$fields= func_get_args() ;
echo "$i <input type = text name =". $fields[$i] . ">

With these changes your code works fine.

Regards

Marian

as you can see in your phpinfo() the variables are in _GET not in _POST,
so use _GET not _POST or change your submit method in the form.

Thanks, your tips did the trick. I changed it and it worked! Now I have a
much better understanding of how the script and certain functions work.

Thank you for your help. It works fine now with Marian's tips.
Thank for you tip to use phpinfo(). I'll make use of it more often.

Kind regards...
