Hi guys,

Just wondering if there is a way to insert a variable into the global variable $_POST?

For example:

$_POST[$var]

Cheers for any help in advance.

What?!

Ok maybe I was too vague.

I have a form with a text field but the name of text field is created from a variable eg...

<input type="text" name=<?=$i?> class="text">

And I want to pass this form data to a mysql statement using the $_POST method eg...

UPDATE playerPoints SET week1 = '" . $_POST[$i] . "' WHERE player_id = 2

But this does not work as $_POST does not seem to pick up the variable $i.

Its quite complicated and hard to explain.

Hi gkirk,

Let me summarize things for you.

You have some form elements the name of which you
are generating on the fly. (Dynamically !).
You should be trying the same logic you provide
to build up the name and access the variable
when the from is submitted.

Well this thing will help you debug a bit.
print the whole request array.
<?
echo "Request";
print_r($_REQUEST);
echo "Get";
print_r($_GET);
echo "Post";
print_r($_POST);
?>

This will help you check whether you are reciving the variables
in your script.

Hi jmukesh,

Thanks for your reply.

Ok so I am receiving the variables but now I need to insert these values into my sql statement and this is what I am having a problem with.

The name of the form I am posting is a variable named $i so in theory to access this using $_POST I should use $_POST[$i] but this does not work???

>> so I am receiving the variables

May be you store these into some other variables before writing $query
$_POST[] is an array of $_POST[0], $_POST[1] etc.
And this may be a reason for error if you are using $i as 0, 1, 2..

loop through $_POST[] and store into another array ppoints[]
( you are getting the POST[], note that if you are starting from $i=0,1,2.., your initial $_POST[$i] may not be $_POST[0] since $_POST[] is an array and there may be some FORM variables before you wrote name=<?=$i?> in FORM, so another idea is to write name=<?='abc'.$i?>

UPDATE playerPoints SET week1='ppoints[$i]' WHERE player_id=2

I hope u'll resolve:)

I have resolved the problem using a for each loop on the $_POST array.

Thanks for all your help:D
