GetTextAreaValue

string
CForm::GetTextAreaValue(
 int answer_id,
 array answer,
 mixed form_values = false
)

If the array, passed in the parameter form_values, is initialized (for example, when editing the [link= 6660053#result]result[/link]), the method returns the current value of the "textarea" type [link= 6660053#answer]answer[/link], ID of which is passed in the parameter answer_id.

If the array, passed in the parameter form_values, is not initialized (for example, when creating new [link= 6660053#result]result[/link]), the method will return the default value for this [link= 6660053#answer]answer[/link] (that is, what is set in the answer["VALUE"]).

Non-static method.
