Saving to database via Ajax

Question

I have a situation,I need to add lot of text to server (via ajax & php).Each is happeening by clicking on a add button.In order to reduce round trip.I am planning to give a save all button so once I store everything in client side and I can save all together to database via ajax so only one round trip.

I have 6 input fields and needs to save this info everytime

My planning

Store everything in a JavaScript hidden variable and itreate this in php side and save it. I will have to store lot of text in hiden field.Is my approach correct ? any better way ?

This approach sounds fine. Without further details thats all i can say — Steve

You can use the local Storage Object of Javascript to store the data e.g. as a json-string and send this json to your server — empiric

hidden fields or javascript arrays ? which is good and easy and secure. — atc

Have in mind that hidden-fields in HTML can be seen and (in the worst case) manipulated by the user — empiric

You dont need to store it on hidden fields, just make a JSON object containing the data you want and then send it to the server throught ajax.

You can create the JSON object this way:

var jsonObject = {'name': $('#name').val(), 'city': $('#city').val()};

And then you send it to PHP throught AJAX:

$.ajax({
    type: 'POST',
    url: 'some.php',
    data: jsonObject,
    dataType: 'json'
}).done(function() {
    alert('success');
}).fail(function() {
    alert('error');
}).always(function() {
    alert('complete');
});

I would recommed to set the dataType option of ajax to json in this case

That depends on how the Server will return the data. But i agree with you, better to work with json-json format.
