\ValidFormBuilderGroup

Create a group of radio buttons or checkboxes

Use the Group object to create a group of either Radio buttons or Checkboxes.

Example 1; Standard way of creating a checkbox/radio button list

$objForm->addField(
    "rating",
    "Rate ValidForm Builder",
    // Replace with ValidForm::VFORM_RADIO_LIST for radio buttons
    ValidForm::VFORM_CHECK_LIST
);
$objSelect->addField("Awesome", 1);
$objSelect->addField("Great", 2);
$objSelect->addField("Super Cool", 3, true); // This item is selected by default
$objSelect->addField("Splendid", 4);
$objSelect->addField("Best thing ever happened", 5);

//*** Read submitted value
if ($objForm->isSubmitted() && $objForm->isValid()) {
    // When 'Awesome' and 'Great' is selected, $arrCheckboxValue equals: array('1', '2')
    $arrCheckboxValue = $objForm->getValidField("rating")->getValue();
}

__construct()

__construct(string  $name, integer  $type, string  $label = "", array  $validationRules = array(), array  $errorHandlers = array(), array  $meta = array())

Construct new Group element

See \ValidFormBuilder\Base::addField()

Parameters

string	$name	Field name
integer	$type	Field type
string	$label	Field label
array	$validationRules	Validation rules
array	$errorHandlers	Error rules
array	$meta	The meta array

isDynamicCounter()

isDynamicCounter() : boolean

Checks if this element is a dynamic counter for another element

Returns

boolean —

True if it is, false if not. Default false.

toHtml()

toHtml(boolean  $submitted = false, boolean  $blnSimpleLayout = false, boolean  $blnLabel = true, boolean  $blnDisplayErrors = true) : string

Generate HTML output

See \ValidFormBuilder\Element::toHtml()

Parameters

boolean	$submitted	Force if this field should behave like a submitted field or not (e.g. validate etc.)
boolean	$blnSimpleLayout	Force 'simple layout' output -- no labels and wrapping divs.
boolean	$blnLabel	Show label. Don't show if false.
boolean	$blnDisplayErrors	Show errors (default true). Don't show errors if false.

boolean	$blnDisplayErrors
integer	$intCount

Returns

string

setError()

setError(string  $strError, integer  $intDynamicPosition)

Set a (custom) error message on this specific element

This is mostly used when doing custom server-side validation like validating a username existance. Example:

if ($objForm->isSubmitted() && $objForm->isValid()) {
    $objUserNameField = $objForm->getValidField("username");
    $strUserName = $objUserNameField->getValue();
    if (User::exists($strUserName)) {
        $objUserNameField->setError("User already exists.");
        $strOutput = $objForm->toHtml();
    } else {
        $strOutput = "Account created successfully with the following details:<br />";
        $strOutput .= $objForm->valuesAsHtml();
    }
}

Parameters

string	$strError	The error message
integer	$intDynamicPosition	Set the error message on a specific dynamic field with this index

toJS()

toJS(integer  $intDynamicPosition) : string

See \ValidFormBuilder\Element::toJS()

Parameters

integer

$intDynamicPosition

Dynamic position counter

Returns

string

getRandomId()

getRandomId(string  $name) : string

Generate a random ID for a given field name to prevent having two fields with the same name

Parameters

string

$name

Field name

Returns

string

isValid()

isValid(null  $intCount = null) : boolean

Validate the current field.

This is a wrapper method to call the Validator->validate() method. Although you could validate fields on a per-field basis with this method, this is mostly used internally. For instance, when \ValidFormBuilder\ValidForm::validate() is called, it loops trough it's elements collection and calls this method for each element it finds.

Parameters

null

$intCount

Optional. If set, only the dynamic field with this index will be validated.

Returns

boolean —

True if field validates, false if not.

getDynamicCount()

getDynamicCount(boolean  $blnParentIsDynamic = false) : integer

Get the number of dynamic fields from the dynamic counter field.

Parameters

boolean

$blnParentIsDynamic

Returns

integer —

The dynamic count of this field

setDynamicCounter()

setDynamicCounter(\ValidFormBuilder\Element  $objCounter)

Parameters

\ValidFormBuilder\Element

$objCounter

getValue()

getValue(integer  $intDynamicPosition) : mixed

Get the *valid* value of the current field.

Parameters

integer

$intDynamicPosition

Optional parameter to get the value of a dynamic field.

Returns

mixed —

The valid value of this field. If validation fails, it returns null.

hasFields()

hasFields() : boolean

Placeholder function to determine wheter or not a field contains other fields.

Returns

boolean —

Return false by default.

setName()

setName(string  $strName)

Set a new name for this element

This method also updates the name in the elements Validator instance.

Parameters

string

$strName

The new name

getDefault()

getDefault() : array|string

Get default value

Returns

array|string

setDefault()

setDefault(array|string  $varValue)

Set default value on this element

Parameters

array|string

$varValue

The value to set as default value

__getValue()

__getValue(boolean  $submitted = false, integer  $intDynamicPosition) : string|null

Get the value of the field.

If the value is valid then it will return that value, otherwise the invalid value is returned.

Parameters

boolean	$submitted	Indicate if the form is submitted.
integer	$intDynamicPosition	The position of the field in a dynamic field setup.

Returns

string|null

isDynamic()

isDynamic() : boolean

Check if the current field is a dynamic field.

Returns

boolean —

True if dynamic, false if not.

addCondition()

addCondition(string  $strType, boolean  $blnValue, array  $arrComparisons, string  $intComparisonType = \ValidFormBuilder\ValidForm::VFORM_MATCH_ANY)

Add a new condition to the current field

For examples, check \ValidFormBuilder\Condition

Parameters

string	$strType	Define the condition type. This can be either `required`, `visibile` or `enabled`
