$this and_(
HTML_QuickForm2_Rule
$next)

Adds a rule to the chain with an "and" operator

Evaluation is short-circuited, next rule will not be evaluated if the previous one returns false. The method is named this way because "and" is a reserved word in PHP.

Return: first rule in the chain (i.e. $this)
Throws: HTML_QuickForm2_InvalidArgumentException when trying to add a "required" rule to the chain
Access: public

Parameters:

HTML_QuickForm2_Rule $next —

mixed getConfig(
)

Returns the rule's configuration data

Return: Configuration data (specific for a Rule)
Access: public

string getJavascript(
[bool
$outputTriggers = true])

Returns the client-side representation of the Rule

This creates an instance of either qf.Rule or qf.LiveRule (depends on $outputTriggers) with initialization parameters:

callback: {@see getJavascriptCallback()}
element ID to set error for if validation fails
error message to set if validation fails
triggers: {@see getJavascriptTriggers()} (only for qf.LiveRule when $outputTriggers is true)
chained rules, array of arrays like in $chainedRules property

Throws: HTML_QuickForm2_Exception if Rule or its chained Rules can only be run server-side
Access: public

Parameters:

bool $outputTriggers — Whether the Rule will be run onblur / onchange

[ Top ]

string getJavascriptCallback(
)

Returns the client-side validation callback

This essentially builds a Javascript version of validateOwner() method, with element ID and Rule configuration hardcoded.

Return: Javascript function to validate the element's value
Throws: HTML_QuickForm2_Exception if Rule can only be run server-side
