Hi Community

is there a way that a PHP script can count the number $_post items being sent to it, if that number is knot known.

fro example if a user selects form options: option1, option3, option6 and submits the form

can the following PHP script know to only get 3 $_post items, or can i right a loop to only assign the correct number of $_post variables?

thanks
Joe

[code=php]$num = count($_POST);

echo $num;[/code]

this is now how I retrieve the $_POST data.

[code=php]$arrtime = array();
$cou=0;
foreach ($_POST as $value)
{
$arrtime[$cou] = $value;

$cou++;
}
$submit = array_pop($arrtime);[/code]

@MindzaiMar 01.2010 — You code seems a little redundant. It is effectively the same as:

[code=php]$submit = array_pop($_POST);[/code]

However even if you do need to loop, you don't need the counter variable.

[code=php]
$arrtime = array();
foreach ($_POST as $value) {
$arrtime[] = $value;
}
$submit = array_pop($arrtime);[/code]

cheers for the help ?

[code=php]$arrtime = array();

foreach ($_POST as $value)
{
$arrtime[] = $value;
}
$submit = array_pop($arrtime);[/code]
