Foreach element in $_POST?

[IWP506]

Hey

Is there a way to go through each element in the $_POST supervariable?

I'm making a page with dynamic forms, so I don't know for sure how many
$_POST variables there will be (the number of textboxes, radio buttons,
etc changes).

How can I either count them or do a foreach loop to do this?

Thanks

iwp506,

Easy, just treat $_POST as an array and use foreach.

Don't forget to make the post values safe before using them if they were
input by the users...

Following on from Carl's message. . .

Further don't forget that elements of $_POST may be arrays in their own
right. eg Checkboxes. Here is a snippet of code as illustration
#---------------------------------------------------------------------
function POSTget($VarName,$tidy=TRUE){
# read POSTed value from HTTP_POST_VARS
# Normally we'll tidy up the input to remove leading and trailing spaces
and control chars
# but this can be overridden.
#---------------------------------------------------------------------
if (isset($_POST[$VarName])){
$rv = $_POST[$VarName];
if(!is_array($rv)){
if ($tidy) {$rv = TidyInput($rv);}
}
}else{
$rv='';
}
return $rv;
}

fun with forms... iterate_form() not only spits out the values, but
will give you the $var = $_POST['var'] code for the receiving page...
have fun

function iterate_form()
{
echo "<b>Values:</b><br>";
foreach($_POST as $key => $value)
{
echo $key . " = " . $value . "<br>";
}
echo "<br><br><b>Happy Coding:</b><br>";
foreach($_POST as $key => $value)
{
echo "$". $key . " = \$_POST['". $key . "'];<br>";
}
build_back_form();
exit;
}

function build_back_form()
{
echo "<form name='error' method='post' action='".
$_SERVER['HTTP_REFERER'] ."'>\n";
foreach ($_POST as $key => $value)
{
echo "<input type='hidden' name='" . $key . "' value='" .
$value . "'>\n";
}
echo "<input type='submit' name='submit' value='Go
Back'></form>\n";
}
