Creating PHP Forms by hand is a tiresome, repetitive chore - and when you add in Ajax functionality for a smoother, better user experience it can quickly become complex.
Apeel PHP Code Generator Pro whip's up PHP Forms with advanced Ajax functionality in no time - just sit back and let it do all the hard work for you.
Automation also means less mistakes than when creating a large number of forms / fields by hand.
When selecting data in another table there is no "one size fits all" which is why several lookup field types are built-in and can be applied to any lookup field - Drop down Lists (for lookups with minimal options), Autocomplete (type in part of the value you are looking for and it will present a list of options), and search forms (useful when you need to search against multiple criteria - e.g. last name and postcode in a large customer table.)
The Data Grid allows you to resize/re-order columns, re-order data by one or more columns, filter, edit and export.
The user can filter data by zero or more criteria, using all relevant operands.
