Datepicker Unavailable dates (data retrieved from database) - php

Question

I'm trying to get dates from my database and put them in an array where it would be stored in json.
MAIN.PHP
$('#datepicker').focus(function(){
$.ajax({
url: 'getDates.php',
data: "artist_name="+$('#name').html(),
dataType: 'json',
success: function(data)
{
}
});
})
getDates.php
$fullname = $_GET['artist_name'];
$result = mysql_query("SELECT .... FROM .... WHERE ... ='$fullname'")
$arraydates = array();
while($details = mysql_fetch_assoc($result)) {
array_push($arraydates, $details['event_date']);
}
echo json_encode($arraydates);
I've managed to put all the dates from the selected artist in the "arraydates".
I found this on google:
var unavailableDates = ["21-8-2013"];
function unavailable(date) {
dmy = date.getDate() + "-" + (date.getMonth() + 1) + "-" + date.getFullYear();
if ($.inArray(dmy, unavailableDates) == -1) {
return [true, ""];
} else {
return [false, "", "Unavailable"];
}
}
That's fine. But now I'm trying to get the results from the array (within getDates.php) and use them in the "main.php". So basically I want to use the data like above with "unavailableDates" array. (and thus, disable the specific dates within the jquery date picker).
Instead of having "unavailableDates", I have the "arraydates". I don't really know how can I use my array inside the "unavailable" function.
I'm not really good with json, actually it's my first time I used json. So could anyone please help me with that?

Answer 1

you can use jquery:
//...
success: function(data){
var arrayLength=data.length;
for(var i=0;i<arrayLength;i++){
if(unavailable(data[i]){
//your code here
}
}
}
//...

Answer 2

The ajax will return $arraydates in a JSON format. Use parse.JSON(returned value)
for example
success: function(data)
{
var unavailableDates = parse.JSON(data);
//Your code ....
}
Hope that helped.
