Question

I have dynamically loaded the values of checkbox using php, n m using AJAX in that page to call the processing page.

<form name="form1" id="form1" action="javascript:wait1();getPass('go.php?**place**='+ document.form1.place.value);" method="post" enctype="multipart/form-data">


<input name="place[]" type="checkbox" value="<?=$ro['article_title']?>" /><?=$ro['article_title']?>

As the checkbox consists of arrays, I do not get the values.

Plz help..

Thanks in advance.

Use the “array style” to access the form’s properties, like form1['place[]']. As this is a checkbox, several values can be selected and form1['place[]'] will return a node list. You could build the URL by traversing through the list:

var places = document.form1['place[]'];

var checked_places = [];
for (var i = 0, l = places.length; i < l; i++) {
    if (places[i].checked) {
        checked_places.push('place[]=' + places[i].value);
    }
}
var url = "go.php?" + checked_places.join('&');

But why do it like that? As you are POSTing the form anyway, why not just read the values via $_POST on the server side?
