DBO Form Widget

This is a very useful component that can be used to generate an edit form of the data, which is a very important component of the MST Library 3.1, which enables the loop nesting of the dbo form and the dbo form, is controlled in a form, and supports the DBO The custom widget component is nested again in the form. Many PHP frameworks, which write the form generation in the function, are understandable, but you cannot receive the performance cost of iterating over the user function when generating a form, and building a PHP and HTML-mixed code is much better than the performance of the loop execution function. And, most of the time, we know the structure of a data object, we have defined the value type of each field of the data object, we really do not need to manually write what form, or to use the code to judge, this with select, that with textarea or something. The image of the pair to manipulate $target must be based on Mst_dbo's example if (!isset ($data) | |!is_object ($DATA) | |! $data instanceof mst_dbo) { Echo ' $data not a mst_dbo instance! '; } else { Get the Contact module $model = Get_class ($data); Definition $columns If undefined, the Mst_dbo interface is taken if (!isset ($columns)) $columns = $data->getformcolumns ($data); if (Empty ($columns) | |!is_array ($columns)) { echo ' undefine form columns!
