why are arrays being dropped, and individual array elements that need to, not?
hi. i am at my end's wits here, this one is especially for Ray_Paseur and kaufmed to toggle over.
i have used the functions developed in other php/regular expression posts - to retrieve the form and elements as an array, giving info on wether the element is disabled or not.
now the weird thing is, the array gets emptied when i wish to step through it and prepare the POST strings? 0o
the code i am talking about is as follows:

the code i am talking about is as follows:
// load form
$url = "https://lmx.leads360.com/web/login.aspx";
$browser = file_get_contents($url);
$forms = getforms($browser);
$form = "form1";
// drop hidden elements and populate form
for ($i = count($forms[$form]) - 1; $i > 0; $i--) {
if (($forms[$form][$i]["checked"]=="false" && ($forms[$form][$i]["type"] == "checkbox" || $forms[$form][$i]["type"] == "radio")) || $forms[0][$i]["disabled"]=="true") {
unset($forms[$form][$i]);
}
if ($forms[$form][$i]["name"]=="usernameTextBox") {
$forms[$form][$i]["value"]="user@domain";
}
if ($forms[$form][$i]["name"]=="passwordTextBox") {
$forms[$form][$i]["value"]="P455W0rd";
}
}
// print_r of the array here prints as expected but it's not removing the items - ergo something is wrong with the if statement around the unset function - but i cannot see what -_-
// print_r($forms);
// compile post strings
$action = $forms[$form][0]["action"];
$url = http_build_url($url,$action,HTTP_URL_JOIN_PATH);
$data = "";
for ($n = 1; $n < count($forms[$form]); $n++) {
$data .= ($n > 0)?"&":"".$forms[$form][$n]["name"]."=".urlencode($forms[$form][$n]["value"]);
}
// print post data
echo $url."\n".
$data;
the root question is i guess, what the heck am i doing wrong that it does not return as expected???
Just perusing your code I noticed at the end of line 8 you have $forms[0][$i] where elsewhere on that line you have $forms[$form][$i]. I'm going to look a little deeper, but wondered if that was correct.
Can you either supply the getforms() function or a print_r($forms) before you start processing it please.
At this stage we don't know if the issue lies outside of this code.

The way I read this, your $data should be a string of ampersands "&&&&" since that's all that will be appended to $data if $n>0 which is always is since it starts with 1.

Try
The third expression doesn't terminate at the .
So you're current code looks like ..
rather than ...
$data .= (($n > 0) ? "&" : "") . $forms[$form][$n]["name"] . "=" . urlencode($forms[$form][$n]["value"]);

So you're current code looks like ..
if ($n >0) {
$data .= '&';
} else {
$data .= '' . $forms[$form][$n]["name"] . "=" . urlencode($forms[$form][$n]["value"]);
}
rather than ...
if ($n >0) {
$data .= '&';
} else {
$data .= '';
}
$data .= $forms[$form][$n]["name"] . "=" . urlencode($forms[$form][$n]["value"]);
Maybe it simply easier to ...
if ($n >0) {
$data .= '&';
}
$data .= $forms[$form][$n]["name"] . "=" . urlencode($forms[$form][$n]["value"]);

the current code is below the returned array, the function getforms behaves as expected and returns the following array from the print_r in line 17:

print_r($forms);

}
// print action & post data (post data remains blank :|)

thanks this worked :D can't believe i missed something small like that... :o

now the only problem is to figure out why the heck it's emptying the array after creating the post string. :(
the code has changed to follows:
