Okay, first thing, I had a lot of trouble thinking of a title for this, and also of what to search for in Google. So that may just be me being stupid, but here is what I would like you help with.
I have a form, that has a button that will add additional input fields, but I would like the the name of the field to iterate everytime the button is pressed. E.g. the first time it will be:
<input type="textfield" name="field1" value=""/>
Then the second time it is pressed, it will be:
<input type="textfield" name="field2" value=""/>
I also have a small example of what I currently have here: /
Please let me know if you can help me, or if you require more info thanks :)

Reset to default 6The best way to handle this is to name them all field[].
When handled by the server-side code, it will build an array for you. For instance, in PHP you would get $_POST['field'][0], $_POST['field'][1] and so on.
For your example:
JQuery
var i=0;
$('span.add').click(function () {
$('<input>').attr({
type: 'textfield',
name: 'program'+i
}).appendTo('#addsoftware');
i++;
});
JSFiddle.
But @Kolink-s answer is much better.
Edit: I just saw the previous posts after sending this. Using an array would definitely be better, and JQuery is always nice :).
Just use some javascript:
<HTML>
<HEAD>
<TITLE>Dynamically add Textbox, Radio, Button in html Form using JavaScript</TITLE>
<SCRIPT language="javascript">
idx = 0;
function add() {
//Create an input type dynamically.
var element = document.createElement("input");
//Assign different attributes to the element.
element.setAttribute("type", "textfield");
element.setAttribute("name", "field" . idx);
element.setAttribute("value", "");
idx++;
var foo = document.getElementById("fooBar");
//Append the element in page (in span).
foo.appendChild(element);
}
</SCRIPT>
</HEAD>
<BODY>
<FORM>
<H2>Dynamically add element in form.</H2>
Select the element and hit Add to add it in form.
<BR/>
<INPUT type="button" value="Add" onclick="add()"/>
<span id="fooBar"> </span>
</FORM>
</BODY>
</HTML>
I took this example from: Add more text fields dynamically in new line (html)
