How to post array from javascript to php ?

Question

I want to post an array using Jquery Ajax to php. Is this possible ?

Thanks

EDIT:

I tried following :

type: "POST",
url: "path",
data: "styles=" + strstyles + "&templateId=" + custTempId, //strstyles is an associative array
dataType: "json",
success: function (data) { .....}

but, styles hold no data. I spent a lot of time, before adding data type to the declaration. What can be the reason for "styles" being posted as null ?

Second Edit

I want to post style sheet dom object and save the class names and properties to DB. With the above edit, adding datatype did not help. I think it is b'coz the string is not in json format as follows -

    {"a":1,"b":2,"c":3,"d":4,"e":5}

As the my string has double quotes, it is not following the format, and I think that's the reason, I'm getting an empty array. How can I handle this ?

Answer 1

With jQuery it is very easy:

$.ajax({
    type: "POST",
    url: location.href,
    data: data,//data is array
    dataType: "json",
    success : function () {
        // Something after success
    }
});

Answer 2

You can use in following way too

$.ajax({

type: "POST",
url: location.href,
data: ({'data[]' : array}),//array is array
dataType: "json",
success : function () {
    // Something after success
}

});

if you don't want to use JSON, PHP can automatically create arrays from Html forms so you could do something like this:

type: "POST",
url: "path",
data: "styles[key1]=" + strstyles.val1 + "&styles[key2]=" + strstyles.val2 + ... + "&templateId=" + custTempId
...

that is if you want to have an associative array in php, but if you want just an array you could do

data: "styles[]=" + strstyles.val1 + "&templateId=" + custTempId

Answer 4

In POST call you dont use & , So your code should be something like

type: "POST",
url: "path",
data: {styles: strstyles , templateId: custTempId}, //strstyles is an associative array
dataType: "json",
success: function (data) { .....}

is that point clear? So coming to my solution,

1. you should download JSON parser from http://www.mediafire.com/?x6k3su7bbdrcta8.
2. Create object strstylesOBJ, code: var strstylesOBJ = {};

3. insert your strstyles array into strstylesOBJ and stringify it then pass to it in your post call

    strstylesOBJ.styles = strstyles;    
    strstyles = JSON.stringify(strstylesOBJ);
   

4. In PHP code you refecth your array using $strstyles = json_decode($_POST['styles']);

5. do var_dump($strstyles) and please tell what was the output.
