- The API generates XHTML Strict 1.0 compliant code.
- Field validation on the client side to minimize traffic overhead.
- Field validation on the server to enforce validation rules and prevent tempering with the form through SQL injection.
- Client side validation displays inline to improve user satisfaction. No more annoying popups that don’t really tell you anything.
- Creation of complex form structures.
- Completely customizable using CSS rules.
- Automatic creation of field summaries for form mailers in HTML and plain text.
Why use ValidForm Builder?
- Super fast web form creation.
- Get rid of SQL injection problems.
- Create standards based CSS forms. No tables inside.
- Make form entry fun for the user. More feedback from your website.
- Write client- and server-side validation at the same time
The documentation still isn’t as complete as we’d like it to be but it should enable you to get started with the essential basics of ValidForm Builder.

Get started with Conditions and Comparisons
This feature is as new as it is powerful. Since ValidForm Builder 2.0 public beta (that’s what we called it back then), one of the many new awesome features are conditional fields. Here’s a quick preview on how they work:
1) Create two regular fields
$objFirstName = $objForm->addField( "name", "Your name", VFORM_STRING, [ "required" => true ], [ "required" => "This field is required" ] ); $objLastName = $objForm->addField( "lastname", "Last name", VFORM_STRING, [ "required" => true // not required for robin ;-) ], [ "required" => "This field is required" ] );
2) Now, add a condition to the
lastname field. For example, we want it to become optional when
Robin. After all, we all know that Robin’s last name is ‘Hood’. So the way we’ll write that out in plain text would be: lastname-field’s property
required will become
false when name-field’s
value will be
Robin. Here’s how the condition will look in PHP:
$objLastName->addCondition( "required", false, [ new VF_Comparison( $objFirstName, VFORM_COMPARISON_EQUAL, "robin" // Comparison values are case insensitive. ) ], VFORM_MATCH_ANY );
3) When you run this example and type in ‘Robin’ in the name field, last name will become optional. As always with ValidForm Builder: this validates both client-side and server-side!
For more information you’ll just have to dig in the code for now. More than ever we added comments and PHPDoc blocks to all the code we’ve been working on. This release is for those who don’t need to RTFM.
