Help Needed : Creating dynamic charts with php and calling ajax on other page !

princeoo7

On a Journey called Life :P
Skilled
Hello Members,

I am on the verge of completing Final Year B.Sc.I.T Project and need to add reporting module in it!
The Project is an College ERP System !

I need to create many pages with can create reports representing data in pie, doughnut, bar etc alot of them :p

I have tried Highcharts, ChartJS !

I am able to create charts with Highcharts easly but I was not able to workout with ChartJS i.e. passing parameters to it by php :(

Now the problem is that this file is named as process_report.php in process : "process/process_report.php".

Plus i don't know how to add a loading animation like the one flipkart have. I want to add like that loading animation when my data is been called !

module is : AcademiaModule !

so in AcademiaModule / process / process_report.php !

in "AcademiaModule" there is a page called "dailyreport.php" which pass value to" process_report.php" and calls back the result and i am getting the table but the chart is not getting generated with ajax !

if i navigate to that page in browser the i am getting the chart !

I did some search on google but even after applying the solution i am failing !

The reason is that the javascript and its related file are not getting executed ! I have tried turning off the cache of ajax and other stuff but i am failing :arghh:

so what should i do ?

ajax code on dailyreport.php :
Code:
<script src="../js/ajax.jquery.min.js"></script>
        <script>
            $.ajaxSetup({
                // Disable caching of AJAX responses
                cache: false
            });
            $(document).ready(function(){
              $("button").click(function(){
                  var f = $("#first_name").val();
                var r = $("#roll_no").val();
                var y = $("#year").val();
                var c = $("#course").val();
                var l = $("#lecture").val();
                var d = $("#date").val();
                var d1 = $("#date1").val();
                var d2 = $("#date2").val();
                  var url = "process/process_reports.php";                
              
                $.post(
                    url ,
                    {
                        roll_no        : r,
                        course        : d,
                        year        : y,
                        first_name    : f,
                        course        : c,
                        lecture    : l,
                        date        : d,
                        date1        : d1,
                        date2        : d2
                    },
                function(data,status){
                  // $('#result').html(data);
                  $( "#result" ).load( "process/process_reports.php" );
                });
              });

This may be late but you need to make the code in the question more specific. Highlight where you are facing the problem. As far as i can understand you are trying to load an entire file from JS and display it . Instead you need to just get the required data from the process file in JSON/XML and then just fill the data parts that needed to be updated in the daily reports and reload the graph. Move the entire JS into the reports file and just make the process file just output a JSON based on the query . Hope it helps.
