Recursive Mini Converters is our newest tool. This tool is a proof of concept for the notion of recursive forms and recursive mini converters. It is available at http://minerazzi.com/tools/recursive-mini-converters/recursive-mini-converters.php On Recursive Forms If a single-line text field is used for input and output it can be called a two-way field. If this is the only text field that is visible at the front-end of a form, we may call said form a two-way mini form. If this form processes input and output by means of conversion factors, then said form defines a mini converter. If the output becomes the new input, the new output depends on the previous one and a recursive form and recursive mini converter is obtained. With that in mind, we show that recursive mini converters: —can be coded using pure PHP; i.e., no framework, JQuery, or JavaScript are needed. —are suitable for small screen displays like smartphones and tablets.…
