get names of form objects

Anon

Suppose I do not know the names of the form objects in a form posted to a php script. Is it possible to have a php script to extract out the names and values of all the form objects posted to it ? This is useful for dynamically generated forms.

This will do the trick

while (list ($key, $value) = each($HTTP_POST_VARS)) {
print "Key = ". $key ." -- Value = ". $value >" ";
}

Hi,
That works. Thanks! But I have another problem now.

Due to some scripting, I have several text boxes that share the same name but because it is dynamically generated, I do not know the name of the textbox. The values posted with the textbox would be an array. How do I get the array information and also get the name associated with the array ?

I think this will do the trick, I haven't tested it so let me know if it doesn't work

while (list ($key, $value) = each($HTTP_POST_VARS)) {
if (is_array($value)) {
$count = sizeof($value));
print "Array name: ". $value ." ";
for ($i=0; $i < $count; $i++) {
print "Value ". $i ." = ". $value[$i] ." ";
}
}
else {
print "Key = ". $key ." -- Value = ". $value >" ";
}

Thanks. I think that works. After much figuring, I did write something similar as:

while (list ($key, $val) = each($HTTP_POST_VARS)) {
if (is_array($val)) {
$count = count($val));
echo "Key: ". $key ." ";
for ($i=0; $i < $count; $i++) {
echo "Value ". $i ." = ". $val[$i] ." ";
}
}
else {
echo "Key = ". $key ." -- Value = ". $val . " ";
}

It works! Thanks for your help.
