+ +Once loaded you'll add the calendar script to the <head> of your page like this: + +<?php echo js_calendar_script('my_form'); ?> + +The above function will be passed the name of your form. + +Then to show the actual calendar you'll do this: + +<?php echo js_calendar_write('entry_date', time(), true); ?> +<form name="my_form"> +<input type="text" name="entry_date" value="" onblur="update_calendar(this.name, this.value);" /> +<p><a href="javascript:void(0);" onClick="set_to_time('entry_date', '<?php echo time(); ?>')" >Today</a></p> +</form> + + +Note: The first parameter is the name of the field containing your date, the second parameter contains the "now" time, +and the third tells the calendar whether to highlight the current day or not. + +Lastly, you'll need some CSS for your calendar: + +.calendar { + border: 1px #6975A3 solid;
