How to send serialize form data using JQuery if the input element is an array

Question

I have this piece of code in my PHP code:

while ($row = mysqli_fetch_assoc($result))
{
    extract($row);
    echo \"\";
    echo \"

        

Answer 1

If you have to post that array only and not other input fields, this is a clean and quick solution:

var selectedbooks = $('book_form input[name^="bookArray["]').serialize();
alert (selectedbooks); 

Explaination:

The selector ^= selects all elements with a name attribute value starting with 'bookArray', the open square bracket '[' makes sure the element is the array we want to serialize and not just a variable starting with the string 'bookArray'.

Answer 2

You have to replace left square brackets and right square brackets with this:

data: $(this).serialize().replace(/%5B/g, '[').replace(/%5D/g, ']'),
