jquery: on each click event append and increment input name

Question

Each time the button is clicked I need this to increment the name='0fName' by one so the php script sees a unique name and does not overwrite the previous item.

$(document).ready(function(){
    $('#addMember').click(function() {
        for (var i = 0; i <= 6; i++); 
        console.log("addMember was called");
        $("#addfamMember").append("<input type='text' name='0fName'>");
    return false;
});

Future note: that is invalid markup for for loop.

Add a counter:

$(document).ready(function(){
var count=0;
    $('#addMember').click(function() {
        console.log("addMember was called");
        $("#addfamMember").append("<input type='text' name='" + count + "fName'>");
        count++;
    return false;
});

Another approach could be changing a name attribute to fName[]:

$('#addMember').click(function () {
    $("#addfamMember").append("<input type='text' name='fName[]'>");
    return false;
});

In this case data will be sent as fName array which may be more convenient to deal with than with a bunch of separate parameters.

Like epascarello says, add a counter:

$(document).ready(function(){

var counter = 0;

$('#addMember').click(function() {
    console.log("addMember was called");
    $("#addfamMember").append("<input type='text' name='" + counter + "fName'>");

    counter++;
    return false;
});

You need to fix name=counter + 'fName' then it'll be correct

.index() will do this too:

$('#addMember').click(function() {
    var idx = $(':input:last').index();
    $("#addfamMember").append("<input type='text' name='" + idx + "fName'>");
    return false;
});

Fiddle
