passing array to another function

[Anon]

Hello everyone!

I'm passing an array to another function.
Do i have to serialize it first??

or can I just do this:
PRINT"<FORM NAME=\"choiceForm\"
ACTION=\"sessions.php?section=results&nameArray=$nameArray&orgID=$orgID\" METHOD=\"POST\">";

I am trying it this second way. In my results function I have:
GLOBAL $nameArray;

print"$nameArray"; gives me "Array"
which is right.
but print"$nameArray[0]"; Gives me "A"
and print"$nameArray[1]"; Gives me "r"

Anyone know why??
Any help would be greatly appreciated!
Thank you!

Your printing out $nameArray which is, well, an array, in your form action. Instead, try implode(",",$nameArray) and then explode(",",$nameArray) on the script receiving it.

1. You are passing the array to another script through a POST operation. This is not passing an array to another function.

2. You cannot add extra parameters to the 'action' value. You may only put the url of the script without any ? or & parameters
   If you want to send an array as FORM data, you must put the content into an input field (like a hidden field)
   You can either serialize it or add a seperate input field for each element.

i tried serializing $nameArray and passing it to results function by <INPUT type="hidden" name="nameArray" value="$nameArray">

And in results function:
GLOBAL $nameArray;

$nameArray=unserialize($nameArray);

when I did a count it said there was the right amount in there but when I print:
print"$nameArray[0]";

it didn't work. Do I need to unrlncode or something??

... and that only works if you submit the script using the POST method.

It's a lot cleaner to use a hidden field.

urlencode en urldecode do make a difference.
Read the annotations in the manual:

I agree, but she was printing $nameArray out and wondering why its value was "Array"... so i figured don't confues to much 😉
