First of never tell "Reply me fast". That is very rude.

Secondly your question does not make any sense.

if you want the checkbox to be selected then simply:

do below:

Expand|Select|Wrap|Line Numbers

<INPUT TYPE="Checkbox" CHECKED>

if you want it to be judge by php then it can look like something below:

Expand|Select|Wrap|Line Numbers

 
if(certain_condition_fulfilled()==true)

{

 $sel="SELECTED";

}

else $set="";

?>

<INPUT TYPE="Checkbox" <?php echo $set;?>>

I can't understand your question. On checkbox you can only have one answer... Like, gender: masculin or feminin.

A if you use a radio, then you can have more than one answer...

I don't know if i'm helping, but i can't do better with your question!

ATNC33 you have that backwards. Checkboxes are for multiple values. Radio buttons are for a single value from multiple choices.

Anis Nimi, You literally want the values concatenated? Like:

value1value2

or you want them in an array?

array[0]=value1
array[1]=value2

or do you want them as an array in PHP?

You need to clarify your question.

@jd, ATNC33 is not the original poster. I believe they were trying to answer the original poster.

HI ! i think you could try this :

Expand|Select|Wrap|Line Numbers

 <html>

<head>

<title>Serializing Checkbox</title>

<script src="http://code.jquery.com/jquery-latest.js"></script>

<script>

$(document).ready(

        function()

        {

                $("#test").click(

                function() {

                        serializeCheckbox();

                }

                );

        }

);
 
function serializeCheckbox()

{

        var string = '&string=';
 
        var inputs = document.getElementsByTagName('input');
 
        for( var x = 0; x < inputs.length; x++ )

        {

                if(inputs[x].type == "checkbox" && inputs[x].name == 'field') 

                {

                        if(inputs[x].checked == true)

                        {

                                string += inputs[x].value + ',';

                        }

                }

        }

    if (/,$/.test(string)) {

        string=string.replace(/,$/,"")

    }

        alert(string);

}
 
</script>

</head>

<body>

<form>

<input type="button" id="test" value="Click me" />

<br />

<input name="field" type="checkbox" value="blue" />Blue<br />

<input name="field" type="checkbox" value="red" />Red<br />

<input name="field" type="checkbox" value="green" />Green<br />

</form>

</body>

</html>

Hi,
I hope this short code shall help you to understand the whole concept.

Expand|Select|Wrap|Line Numbers

 
$concated_str = '';

if(isset($_POST['checkboxvalues'])){

    $concated_str = implode(',',$_POST['checkboxvalues']);

}

//store $concated_str in the database

In short, use simply implode function. For more detail.
