$_POST array variables

[robcrozier]

ok, im trying to retrieve some variables which were created using a form. Each variable was initialized like so:
[code]

<input name="page_name<? $i ?>" type="text" class="style183" size="40">

[/code]

then if the form is submitted i'm trying to access the variables like this:
[code]

for ($i = 1; $i <= (($_SESSION['no_of_pages'])+2); $i++)
{
    $page_name[$i] = $_POST['page_name[$i]'];
    echo "".$page_name[$i];
}

[/code]

Its the $_POST['page_name[$i]']; bit that i think may be wrong. 

Can anyone shed any light on this?

Cheers!

Hey, Im not too sure myself..

But should it not be

    $page_name[$i] = $_POST['page_name']['i'];

All depends on what you want it to do

Cheers mate!

Well some progress...

It's now printing only the last variable from the array the ammount of times the loop states. Why do you think it's only picking up the last variable???

Not sure I really get it but

I think it should be:

[code]for ($i = 0; $i <= (($_SESSION['no_of_pages'])+2); $i++)
{
    $page_name = $_POST['page_name[$i]'];
    echo "".$page_name;
}
[/code]

why use $i on page_name?
Arrays are zero based. Start at 0.

Hope this helps you. If not, sorry that I might of misunderstood your code.

Try

[code]
    $page_name[$i] = $_POST['page_name']['$i'];
[/code]

?

Going back to the OP's original code. If the input line is
[code]
<input name="page_name<? $i ?>" type="text" class="style183" size="40">
[/code]
as was stated, then none of the solutions will work since the above statement will not really work as intended. The correct line would be either
[code]
<input name="page_name<?php echo $i ?>" type="text" class="style183" size="40">
[/code]
or
[code]
<input name="page_name[<?php echo $i ?>]" type="text" class="style183" size="40">
[/code]

I personally prefer the second form, since then the incoming values can be referenced as values in the $_POST['page_name'] array:
[code]<?php
for ($i=0;$i<count($_POST['page_name']);$i++) {
//
//  do your code
//
}
?>[/code]
