[SOLVED] form/array processing - unknown number of $_POST

[mreish]

I'm building a "Tell a Friend" type script where the user can add input fields so that when they hit submit, there could be 1 or 100 input fields.

 

I can see each field using this:

 

echo print_r($_POST, true);

 

Which gives the output:

 

     Array
     (
         [personalMessage] => message text goes here.
         [email1] => bill@email.com
         [email2] => sue@email.com
         [email3] => 
         [email4] => 
         [email5] => 
         [email6] => 
         [description] => Tell a friend 
     )

 

But because there are other elements in the $_POST array (such as personalMessage and description) I'm not sure how to parse for the email elements.

 

Any constructive input or tips is most welcome!

in your form, change name = 'email1', name = 'email2' etc... to name = 'email[]' for all of them and then

 

foreach($_POST['email'] as $email) {
   // example 
   echo "$email <br />";
}

Aw man, I knew that but I don't do it very often so I completely forgot about it! 

 

Thanks a ton!
