This document is for a version of CakePHP that is no longer supported. Please upgrade to a newer release! The FormHelper is a new addition to CakePHP. Most of the heavy lifting in form creation is now done using this new class, rather than now deprecated methods in the HtmlHelper. The FormHelper focuses on creating forms quickly, in a way that will streamline validation, re-population and layout.

The FormHelper is also flexible - it will do almost everything for you automagically, or you can use specific methods to get only what you need. This special method outputs an opening form tag. All parameters are optional. If create is called with no parameters supplied, it assumes you are building a form that submits to the current controller, via either the add or edit action.

The default method for form submission is POST. The form element also is returned with a DOM ID.

The ID is generated using the name of the model, and the name of the controller action, CamelCased. This will place your form data into the array: This can be handy for short forms that may not represent anything in your database.

This is to be used if there are any file elements inside the form.

The absence of the proper enctype attribute will cause the file uploads not to function. This allows CakePHP to emulate proper REST support in web browsers. The action key allows you to point the form to a specific action in your current controller. The supplied URL can be relative to your CakePHP application, or can point to an external domain.

The FormHelper also includes an end method that completes the form markup. Often, end only outputs a closing form tag, but using end also allows the FormHelper to insert needed hidden form elements other methods may be courses binary options trading system upto 90 accuracy on.

If a string is supplied as the first parameter to endthe FormHelper outputs a submit button named accordingly along with the closing form tag.
