Datepicker help needed

I dont know where to put this so im sorry if its in the wrong place to start!

I have a date picker that inserts into a datebase a number of days in one column so for example:

datearriving would have: 11-8-2012, 12-08-2012, 12-8-2012


What im struggling with is calling the values from the database to grey out the days in my form. Any ideas???

PHP Code:

PHP Code:

---


var disabledDays = [ 

<?php while ($row = mysql_fetch_array($grey, MYSQL_ASSOC)) { 
   echo '"' . $row['datearriving'] . '",';   
} 
?> 
]; 


/* utility functions */ 
function nationalLeavingDays(date) { 
  var m = date.getMonth(), d = date.getDate(), y = date.getFullYear(); 
  for (i = 0; i < disabledDays.length; i++) { 
    if($.inArray((m+1) + '-' + d + '-' + y,disabledDays) != -1 || new Date() > date) { 
      return [false]; 
    } 
  } 
  return [true]; 
} 
function noWeekendsOrLeavingHolidays(date) { 
   
  return nationalLeavingDays(date); 
} 


/* create datepicker */ 
jQuery(document).ready(function() { 
     
    function displayVals() {      
        var numdays = $("#num_days").val(); 
        jQuery('#datepicker').multiDatesPicker({ 
            mode: 'daysRange', 
            autoselectRange: [0,numdays] 
             
             
        }); 
         
    }    
    $("#num_days").change(displayVals);     
    displayVals(); 
});
