                                            }
                                        ]
                                    }
                                    
                                }

                            })

                });
</script>

this part is ajax part of buttons onclick

$("#savecourse").on("click", function() { 
      var code = $("#code").val();
      var section = $("#section").val();
      var coursename = $("#coursename").val();
       var totalduration = $("#totalduration").val();
    $.ajax({
      type: "POST",
      url: "course_add.php",
      data: ({coursecode:code,coursesection:section,ccoursename:coursename,duration:totalduration}),
      success: function(data) {
        window.alert("course added successfully.");
        window.location.reload(true);
      }
    });  
});

and this part is the form.

   <form class="ui form">
              <div class="two fields">
                <div class="field">
                  <label>Course Code</label>
                  <input name="code" id="code" type="text">
                </div>
                <div class="field">
                  <label>Section</label>
                  <input name="section" id="section" type="text" >
                </div>
              </div>
              <div class="two fields">
                <div class="field">
                  <label>Course Name</label>
                  <input name="coursename" id="coursename" type="text" >
                </div>
                <div class="field">
                  <label>Total Duration</label>
                  <input name="totalduration" id="totalduration" type="text">
                </div>
              </div>
              
              <button class="ui submit button" id="savecourse">Save Course</button>
              <div class="ui error message"></div>
    </form>

Hi @cemezgn,

You can do something like that in your click event:

$('#savecourse').on('click', function() { 
  if ( $('.ui.form').form('is valid') ) {
    // Do an AJAX call.
  }
})

The following is a standard reply.

The problem is caused by your “click” event on the button. It’s not validating anything; it’s just grabbing all the form’s values and sending them using AJAX.

You can check the validity of the form’s values by using the behaviors described in the documentation: http://semantic-ui.com/behaviors/form.html#/settings
