What I do when I need multidimensional arrays from forms, is name my
variables:
<INPUT NAME="i::foo::bar" VALUE=" ... ">
i.e., I delimit the dimensions with "::". Then, on the page they are posted
to, I do:
<?
parseInputVars('i');
?>
And here is the code for that function, which looks for all the variables
that start with 'i::' and creates the multidimensional array needed.
<?
###############################################################
#
# parseInputVars
#
# - parses HTTP_POST variables into a multi-dimensional
# arary, using '::' as the delimiter, and also runs
# a function on each element of the array during parsing,
# and optionally another function on the entire array
# after parsing
#
function parseInputVars($var, $function=false, $global_function=false) {
global $HTTP_POST_VARS, $$var;
if (is_array($HTTP_POST_VARS)) {
$temp = '';
foreach($HTTP_POST_VARS as $k=>$v) {
$s = explode('::',$k);
if ($s[0] == $var) {
$s2 = array();
foreach ($s as $k2=>$v2) {
if ($k2) {
$s2[] = $v2;
}
}
if (is_object($v) || is_array($v)) {
$temp .= sprintf("\$t[%s] =
unserialize(urldecode(\"%s\"));",
join('][',$s2), urlencode(serialize($v))
);
} else {
if ($function) {
$temp .= sprintf("\$t[%s] = %s(urldecode(\"%s\"));",
join('][',$s2), $function, urlencode($v)
);
} else {
$temp .= sprintf("\$t[%s] = urldecode(\"%s\");",
join('][',$s2), urlencode($v)
);
}
}
}
}
eval($temp);
$$var = $t;
if ($global_function) {
$global_function($$var);
}
}
}
?>
