form & post

[liorda]

Hi all!

in the form i have many checkboxs with same name, only different values.
in the cofimiration php file, when using <?php echo $_POST "recipient"]; ?>, it only echos the last checkbox value.

how can i make it echo all the values that is "on"?

thanks!

<?
if (!isset($_POST['submit'])) 
{
	echo '
	<form action="" method="POST"> 
	please select numbers:<br>
	<input type="checkbox" name="numbers[]" value="1">1<br>
	<input type="checkbox" name="numbers[]" value="2">2<br>
	<input type="checkbox" name="numbers[]" value="3">3<br>
	<input type="checkbox" name="numbers[]" value="4">4<br>
	<input type="checkbox" name="numbers[]" value="5">5<br>
	<input type="submit" name="submit" value="submit"> 
	</form> 
	'; 
} 
else 
{ 
    if (isset($_POST['numbers'])) 
    { 
        echo 'you selected the following '  . count($_POST['numbers']) . ' number(s):<br><br>'; 
        foreach ($_POST['numbers'] as $value) 
        { 
            echo $value . '<br>'; 
        } 
    } 
    else {echo 'you did not select any numbers';} 
} 
?>

but what if the name of the checkboxes is without the []?
i can't use it because i have a function in the refering page the uses name in loop.

thanks, and it's very elegant, though. 🙂

that actually was the whole point of my example: to illustrate how to return form data (numbers[]) as an array which makes it very simple to iterate through on the form processor. your original post said all of the form elements have the same name. that is your problem. if they all have the same name then the last one will overwrite all of the previous ones. this is the whole purpose of using a compound variable type (like an array) to store similar data (like a list of checkboxes).
you have 2 choices:
1. use an array like i had suggested (which as you yourself said is "elegant")
2. hard code unique names for each individual checkbox and validate them individually on the form processor (which is incredibly inelegant, in my view).

i'll change it to an array.

thanks a lot!
