and passing the variable to a bootstrap modal, for some reason I am getting the following error:Notice: Undefined index: name

$(document).ready(function(){
  $(document).on('click','.idname', function(){
      alert('est123');
    //e.preventDefault();
    //var data = $(this).serialize();
    $.ajax({
      type: 'POST',
      url: 'index.php',
      data: ({name:"test"}),
      cache: false,
      success: function(data){
        $('#results').html(data);
      }
    })
    return false;
  });
});

Solution 2

try

$(document).ready(function(){
  $(document).on('click','.idname', function(){
      alert('est123');
    //e.preventDefault();
    //var data = $(this).serialize();
    $.ajax({
      type: 'POST',
      url: 'index.php',
      data: {name:"test"},
      cache: false,
      success: function(data){
        $('#results').html(data);
      }
    })
    return false;
  });
});

That is remove the "()" around the data

Nice, but you should wrap your code block in <pre>...</pre> tags instead of <code>...</code> tags.

See how much nicer it looks now? :D
