通过ajax将数据传输到php

Question

I resolve the problem with the format but I have a new problem in the transfer of the data by ajax to my php.

Ajax send data like:

$.ajax({
url: 'http://localhost/test-fullcalendar/php/add_evento.php',
data: 'title='+ title+'&start='+ start +'&end='+ end ,
type: "POST",
success: function(json) {
alert('OK');
}
});

And add_evento.php receive like:

$title=$_POST['title'];

$start=$_POST['start'];

$end=$_POST['end'];

It says me 'undefined index' in all of the variables so I included 'isset' in anyone. After that I did an echo of the variables and none receives correctly the data, all of them didn't show anything. I try to changing the data line to:

data: {title: title, start: start, end: end},

and the method POST to GET and still doesn't working.

How I can check if I sending correctly the data? I'm writing alert(data.title); inside ajax function but don't show anything.

Answer 1

Your data is incorrect. Try this:

$.ajax({
  url: 'http://localhost/test-fullcalendar/php/add_evento.php',
  data: {"title": title, "start": start, "end": end},
  type: "POST",
  success: function(json) {
    alert('OK');
  }
});

If type: "POST" you can access data with $_POST and if type: "GET" you can access with $_GET

Answer 2

 data: 'title='+ title+'&start='+ start +'&end='+ end

This should be changed to:

 data: {title:title, start:start, end:end}

You can also do the call like this:

$.post('http://localhost/test-fullcalendar/php/add_evento.php',{title:title, start:start, end:end}, function(json) {
alert('OK');
});
