Data Dump V2
Data Dump V2 is the easiest web page form testing software I have used. It displays whatever information it receives.
Install a copy of Data Dump V2 on your server and have a wonderful testing tool available.
The first version of Data Dump was published in 2011. This second version added two information elements (form upload information and raw POST data).
Here is a short explanation of each information item that Data Dump V2 intercepts and publishes.
-
Method POST — When a form with
method="post"is submitted to the data dump software, Data Dump V2 will display the form field names and their values. All form fields that are submitted are displayed, including hidden fields and, if applicable, button names and values. -
Method GET — Similar to method POST, when a form with
method="get"is submitted to the data dump software, the received names and values are displayed. -
Uploaded FILE Data — When using a form to upload files (form field
type="file"), the upload information is processed with a special$_FILESarray. Formtype="file"fields can be single or multiple files; and may have unique or identical field names (with[]appended). Data Dump V2 will display an array of all upload data (name, size, type, …), so any combination of form upload fields can be represented. -
Raw POST — When the form data is sent to the data dump software with method POST, but not formated as standard name=value information, then Data Dump V2 publishes a copy of what was submitted. (An example of unformatted information is server software submitting the data instead of a web page form — JSON-encoded data, an image file, or any other data not formatted as normal name=value pairs.)
-
Cookies — If the data dump software receives cookie information from the browser, the cookies are displayed.
-
Environment Variables — The PHP script maintains a number of environment variables. They are displayed here in case some of the information is useful. For example, it shows what method was used to submit the form.

Installation is copy and paste: Name the file datadump.php or other preferred *.php file name. Make a note of the installed software's URL.
To use, temporarily replace the action value of your form tag with the URL of the installed Data Dump V2 software.
I think you will appreciate the data dump tool, especially if you do occasional or more website developing.
