"Enhance user experience with AJAX for selecting multiple checkboxes or performing mult

Hey there! So, I've got a question about handling multiple checkboxes with the same name in a form. Here's an example of what I'm working with:

<input type="checkbox" name="myname[]" value="1" />
<input type="checkbox" name="myname[]" value="1" />
<input type="checkbox" name="myname[]" value="2" />
<input type="checkbox" name="myname[]" value="3" />
<input type="checkbox" name="myname[]" value="4" />

I prefer to keep things simple and avoid using jQuery for this particular task. My goal is to serialize this form correctly for use in an ajax post request in PHP. Can you help me out with that?

Answer №1

To easily retrieve all the checked checkboxes, you can use the document.getElementsByName method to obtain them and then iterate through to find out which ones are checked.

var selectedCheckboxes = [];
var allCheckboxes = document.getElementsByName("mycheck[]");
for(var j = 0; j < allCheckboxes.length; j++){
    if (allCheckboxes[j].checked)
       selectedCheckboxes.push(allCheckboxes[j].value);
}

In PHP, a comma-separated list of values can be treated as an array like this:

selectedCheckboxes.join();   //after testing, yields ---> 2,5,7
