Post Array - Form Data

[stig1]

I have a form with lots of fields.

 

How would I run a loop to get each field name and data into an array, so i can then send it off to a function to process each field name / data differently. Instead of typing all the variables in the main function name for each post.

 

Would a foreach statement work?

Your form data is already in an array, either $_POST or $_GET, depending on the form's method="" attribute.

 

You should however have a master array that contains a list of the expected field names so that you can iterate over the expected fields and detect/ignore any that a bot script or hacker is attempting to send that are not part of your actual form.

i pretty sure i worked it out, i wrote the following:

 

$kv = array();

 

foreach ($_POST as $key => $value) {

    $kv[$key] = "$value";

}

 

to pull the data out i just use the $kv["keyname"] and it seems to work!

the $_REQUEST array will contain passed $_POST and $_GET data regardless of the method declaration.

 

as to protection, use a challenge-response mechanism protection (like captcha/reCaptcha) to prevent automation through your forms. I do not recommend session tickets in hidden form values because they can be bypassed automatically by parsing the html for the hidden values.

I guess you could use that foreach() loop to do that, but it would be identical to assigning it directly, like $kv = $_POST. What would be the point in looping through one array ($_POST) simply to assign its values to another identical array, when you can just use them directly?

agreed - it's redundant.

 

each $_REQUEST['keyname'] can be accessed directly.
