Generating and validating web forms with pear htmlquickform
Just give apply Filter() the function name as a parameter.- to Array() now returns a different structure and calls an external renderer: elements in groups are rendered as seperate elements, every element has a numeric index for key.- Validation rules are validated in the order they were set.- File validation happens only when the file is required.- Direct calls to on Quick Form Event() with 'set Default' and 'set Constant' events won't work anymore, these events have been replaced by an 'update Value' event.- Grouped elements index is now a numeric key only.
PHP, being primarily a web language, sees a lot of reinventing in regards to form display, processing and validation.It allows for validation against regular expressions or custom functions and methods.You can define your own validation rules and apply them to the elements or groups you want.In this section, we will explore the different possibilities Quick Form offers to make validation easier.Quick Form can verify if required elements are filled when the form is submitted.This works with every type of elements or groups, integer 0 is not considered as an empty value.
The HTML_Quick Form::validate() method will scan through each rules in the order they have been set.
Now I had a form that could solicit data from the user and pass it to another function for processing.
However, this is nothing that an ordinary HTML form cannot do.
The new PEAR package HTML_Quick Form-3.0 (beta) has been released at
Release notes-------------* Major changes in this release- Renderers Quick Form now uses external renderers to output the form.
I'm also always keen to separate the presentation logic (typically HTML) from the programming logic (PHP, in this case).
