This is a very useful component that can be used to generate a data editing form. It is a very important component of MST Library 3.1. It can realize the loop nesting of dbo form and dbo form, and control it in one form. It also supports dbo The custom widget component is nested again in the form.
Many PHP frameworks write form generation in functions. This is understandable, but you cannot accept the performance cost of cyclically calling user functions when generating a form. At this time, build a mixed PHP and HTML Code, the performance is much higher than the function of loop execution.
Moreover, most of the time, we know the structure of a data object and have defined the value type of each field of the data object. We really don’t need to manually write any form, or use code to judge. This uses select , that uses textarea or something.
