Nabi,

There was a small mistake in the earlier code that i had posted (I had used 'i' instead of 'j' at one place in the for loop). I have edited that part and fixed it. Try the code that i have posted and see if it works for you.

Nabi, there are multiple ways to access the form in a document. A form is maintained in an array inside the document object. Here are the ways you can access the form:

This way, you first access the forms array and then access the first form in that array. You can change the form index from 0 to some other index depending on how many forms you have and which form you want to access. In the example that we tried out, we just had one form and hence form[0].

This way, you access the forms array and then access the form you are interested in, by its id. In our example, we had given our form the id form1 and hence document.forms.form1

This is a generic way of accessing any element in the document by its id.

All 3 of these methods are going to return you the reference to the form.

Do you mean you are having problem trying out the example on the checkboxes? I see that you have specified the name of the checkbox as edu[]. Change it to edu. Something like:

Reading through your post, again, i think i understand what you are asking. You want a array of values (from the checkbox) to be passed to your servlet. When you specify the checkboxes as:

the servlet will be able to get all the checked values by using the getParameterValues method available on the request object. Have a look at getParameterValues(java.lang.String)

As per the javadoc of this method:

Returns an array of String objects containing all of the values the given request parameter has, or null if the parameter does not exist.

If the parameter has a single value, the array has a length of 1.

So, all you have to do in your servlet is

This way you will get all the checked values.

You can let the PHP interpreter know that you are sending multiple values by appending '[]' to the end of the element's name attribute.
