Description
Object | --Persistent | --Component | --FormValidator
Located in File: /jsval/formvalidator.inc.php
This component provides an easy way to validate your form
Use this component to get an easy way to validate your form, by checking for specific data.
Rules for validation are stored on the Rules property, which is an array, in which every element is a rule to check.
After that, you can use javascript to call the validation function, which is named as the component plus _validate, for example fvValidate_validate().
That function shows any message if required and returns false if validation is not met, true otherwise.
- <?php
- function Unit464JSSubmit($sender, $params)
- {
- ?>
- return(fvValidate_validate());
- <?php
- }
- ?>

property Rules (line 101)
array Rules
This property specifies the rules to validate the form
Use this property to specify the validation rules to test against. In Delphi for PHP, there is a property editor you can use to setup this property, if you want do it in runtime, you can setup this array dynamically.
- <?php
- function Unit464BeforeShow($sender, $params)
- {
- $rules=array();
- $rules[]=array
- (
- 'Control'=>'Edit1',
- 'Equals'=>'Edit2',
- 'ErrorMessage'=>'Edit1 and Edit2 must match and are required',
- 'Name'=>'FieldsMustMatch',
- 'Required'=>true,
- 'MaxLength'=>'0',
- 'MinLength'=>'0',
- 'MaxValue'=>'0',
- 'MinValue'=>'0'
- );
- $this->fvValidate->Rules=$rules;
- }
- ?>

Summary: | __construct | Component constructor [Overrides Component::__construct()] |
 | dumpHeaderCode | Dumps header code required [Overrides Component::dumpHeaderCode()] |
| | dumpJavascript | Dumps the javascript code needed by this component [Overrides Component::dumpJavascript()] |
Defined in class Component |
||
| dumpChildrenJavascript | Dumps the javascript code for all the children |
| dumpFormItems | Dumps code just after the form tag, useful to dump hidden fields for state retrieving for non visible components |
| dumpHeaderCode | Dumps header code required |
| dumpJavascript | Dumps the javascript code needed by this component |
| hasValidDataField | Returns true if a valid data field is attached to the component |
| init | Initializes a component |
| loaded | Initializes the component after the form file has been read into memory. |
| loadedChildren | Calls childrens loaded |
| preinit | Method called before init() |
| serializeChildren | Serializes all children |
| unserializeChildren | Unserializes all children by calling unserialize for all the components |
Defined in class Persistent |
||
| serialize | Stores this object into the session. |
| unserialize | This method uses PHP reflection to iterate through published properties (the ones starting with get) and retrieve the properties stored by a previous serialize() call. |
Defined in class Object |
||
| __construct | Constructs an object and initializes its data before the object is first used. |
| className | Returns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument). |
| classParent | Returns the type of the immediate ancestor of a class. |
