[TYPO3-dev] ExtJS date pickers and date ranges (working prototype maybe for Core?)

[Stefano Cecere]

hi
i just modified the date pickers to support (minimal) date ranges
(i had the date2cal extension patched for this.. but moving to 4.4  
date2cal doesn't work well anymore, and i wanted all native)

the patch is very simple, and maybe it could be expanded to propose it for  
Core 4.5 ?

i did this:

in file t3lib/class.t3lib_tceforms.php i added a custom class to the date  
input element (in my case "fromTomorrow', since i'm interested in blocking  
selection of past dates)

		if (in_array('date', $evalList)) {
			$inputId = uniqid('tceforms-datefield-');
			
			// XCLASS start
			if ($config['range']['lower'] > 0 ) {
				$range = ' fromTomorrow';
			}
			
			$cssClasses[] = 'tceforms-textfield tceforms-datefield'.$range;
			// XCLASS end
			$fieldAppendix = t3lib_iconWorks::getSpriteIcon(
				'actions-edit-pick-date',
				array(
					'style' => 'cursor:pointer;',
					'id' => 'picker-' . $inputId
				)
			);



and file t3lib/js/extjs/tceforms.js cehcks for that class and adds native  
ExtJS minDate value


	convertDateFieldsToDatePicker: function() {
		var dateFields = Ext.select("input[id^=tceforms-date]");
		dateFields.each(function(element) {
			var index = element.dom.id.match(/tceforms-datefield-/) ? 0 : 1;
			var format = TYPO3.settings.datePickerUSmode ?  
TYPO3.settings.dateFormatUS : TYPO3.settings.dateFormat;

			var datepicker = element.next('span');
				
			// XCLASS: added minDate option
			var minDate = (element.dom.className.match(/fromTomorrow/)) ? new  
Date().add(Date.DAY, 1) : null;

			var menu = new Ext.menu.DateMenu({
				id:			'p' + element.dom.id,
				format:		format[index],
				value:		Date.parseDate(element.dom.value, format[index]),
				minDate:	minDate,
				handler: 	function(picker, date){
					var relElement = Ext.getDom(picker.ownerCt.id.substring(1));
					relElement.value = date.format(format[index]);





it  should be easy to pass both lower and upper ranges (as normally  
defined in TCA) putting them as classes of the input element, and then  
modify the JS to use those values.

what do you think?
could it be a useful core feature?
