Hey rottenuncle
How comfortable are you with PHP?
I can add in a filter that’ll allow you to control some additional jQuery. For example, this would be the output and you would control the date part:
jQuery(".datepicker").datepicker("setDate","2011/7/11");
You would have to make sure the default date is in the same format as the date fields. And it would apply the default to all date fields in the form.
For example, you would add in a apply_filter that outputs a date as a string – so using PHP you could make this a static date such as 01/01/2015 or do some PHP magic and calculate the desired date, such as the first Monday of the month.
The filter would then fill in the date in the above.
How’s that sound?
