#calendariffic_input(calendar_is_before_text, text_name, image_source, image_name, date_format, text_value, text_attributes = {}, image_attributes = {}) ⇒ Object

Creates a DHTML pop-up calendar icon and an associated text-box to display the selected date.

calendar_is_before_text: boolean to determine whether the calendar icon is placed before or after the text-box

e.g. true will produce <img ... /><input type="text" ... /> whereas false will generate <input type="text" ... /><img ... />

text_name: specifies the name and id attributes of the text-box. The user MUST specify this value and it MUST be different from the value specified in image_name. image_source: relative path specifying the location of an icon to represent the pop-up calendar.

Several calendar icons are located in public/images/calendariffic

image_name: the name and id you want associated with your calendar icon. The user MUST specify this value and it MUST be different from the value specified in text_name. date_format: the format in which the date will appear within the text_box. See table below for valid abbreviations for date.

a date_format of nil will default to mm/dd/yy.

text_value: the initial value you want to show up within the text box (e.g. ‘07/04/2007’)

if the user passes the string 'today' the text_value will initially display today's date in whichever format is specified by the date_format parameter.
the 'today' string is case-insensitive.

text_attributes: any other attributes that can be placed into an <input type=“text” /> HTML element can be placed here within a Hash. e.g. => ‘myfavoriteclass’ image_attributes: any other attributes that can be placed into an <img src=“” … /> HTML element can be placed here within a Hash. e.g. => ‘cal’
