Solution 1

Thanks for your reply. I'm working on Data-Table with PHP and I want Server-Side Processing to fetch data from database.

I'm posting my code here,

I found solution for this:

<div class="panel panel-default" id="refresh">
    <div class="panel-heading">
        <b>Defects List</b>
    </div>
    <div class="panel-body">

                );
        //output to json format
        echo json_encode($output);
    }

I put my whole code here, so that will help others.

Thanks.

It is important to recognise the difference between .search() and .column().search()

One issue that you have here is that you're using .search() as if it is acting subtractively on the currently filtered set of data. In reality, each call of the .search() function simply runs on the original set of data, so it will only ever return a dataset with 1 filter applied.

To get around this, your best option is to search specific columns for specific values, and take advantage of the chaining available on .column().search()

I would suggest changing your approach to the dropdowns to use data attributes for the column that they wished to filter, for instance:

<select class="table-filter" name="area_id" data-column-filter="2">
    <option></option>
</select>
<select class="table-filter" name="cluster_id" data-column-filter="3">
    <option></option>
</select>

Where the data-column-filter attribute is the index of the column that you want to filter.

You can then write a simple event listener for changes on all relevant select boxes. We can even test the select box to see if it is a multi-select box, and react the event accordingly - we can get an array of the values chosen, and then join them together into a workable regex statement:

$('.table-filter').on('change',function(){
    $('.table-filter').each(function(){

        var filterColumn = $(this).data('column-filter');
        var filterValue = $(this).val();

        if($(this).is('[multiple]'])){
            var filterValuesExpression = filterValue.join('|');
            dataTable.column(filterColumn).search(filterValuesExpression, true, false );
        }else{
            dataTable.column(filterColumn).search(filterValue);
        }
    });

    dataTable.draw();
});

In terms of the logic you use to determine which boxes should and should not be part of the filter at any one time (which boxes are dependent on which others), this is quite separate from DataTables itself.

The following approach relies on a random set of data including fictitious relationships between Area and City/Cluster in order to re populate the cities select list each time a different area is selected.

I commented the code to explain the proceedings as best as possible.

var infoText = "";
            var relationships = {};
            $(document).ready(function() {
                var columns = [
                    {"data": "Date"},
                    {"data": "Type"},
                    {"data": "ASYS"},
                    {"data": "Address1"},
                    {"data": "Area"},

                    {"data": "Status"},
                    {"data": "Landlord"},
                    {"data": "Rooms"}
                ];
                /*generate random relationships between area and cities*/
                generateRelationships();

                var data = generateRandomData(columns);
                var dataTable = $('#exampleProp').DataTable({
                    "data": data,
                    "columns": columns,
                    ordering: false
                });

                $('#areaId').on('change', function() {
                    var selectedAreaId = $(this).val();
                    if (this.value !== '') {
                        if (this.value == 1) {
                            dataTable.column(4).search("Midlands & East of England").draw();

                        }

                        /*trigger city filter*/
                        /*make the options related to this area become "selected"*/
                        $('#cluster_id option').each(function() {
                            if ($(this).val() !== '')
                                if (relationships[selectedAreaId].includes($(this).val())) {
                                    $(this).css('display', 'block');

About me, I'm simple and love to code. I made too much mistakes while coding and learned from them. I love to hear music and play chess.

    I'm trying to apply filters to my data-table with drop-down list box which are dependent. But when i'm trying to select a value from drop-down, data-table takes value from only one drop-down.

    Here is my code:

    Script:

    <script type="text/javascript">
  $(document).ready(function(){
    var dataTable = $('#exampleProp').DataTable({
      "processing": true,
      "serverSide": true,
      "dom": 'lfrtip',
      "ajax": {
        "url": "<?= base_url('Property/fetchProp'); ?>",
        "dataType": "json",
        "type": "POST"
      },
      "lengthMenu": [[50, 100, 200, -1], [50, 100, 200, "All"]],
      // "ordering": false,
    });

    $('#areaId').on('change', function(){
      if (this.value == 1) {
        dataTable.search("Midlands & East of England").draw();
      } else {
        dataTable.search("North East, Yorkshire & Humberside").draw();
      }
    });
    $('#cluster_id').on('change', function(){
       dataTable.search(this.value).draw();   
    });
    $('#prop_type').on('change', function(){
       dataTable.search(this.value).draw();   
    });
    $('#prop_status').on('change', function(){
       dataTable.search(this.value).draw();   
    });

  });
</script>

    In this, Cluster is dependent on Area, but if I select Area, it filters using area only, and not by cluster.

    Here is the code to pick a cluster list from database:

    $('#areaId').change(function(){
         var form_date =
         $.ajax({
          url: "<?= base_url('Property/clusterlistAddPropertyUse'); ?>",
          data: {areaId:$(this).val()},
          method:'POST',
          dataType: 'html',
          success:function(data){
              // $('#cluster_id option:selected').each(function(){
              // $(this).prop('selected', false);
              // });
              $('#cluster_id').html(data); 
              $('.propcluster').multiselect('rebuild');                 
             }
          }); 
    });

    Here is my view code:

    <?php if($this->session->flashdata('success_msg')){ ?>
  <div class="alert alert-success">
    <?php echo $this->session->flashdata('success_msg'); ?>
  </div> 
<?php } ?>

<?php if($this->session->flashdata('error_msg')){ ?>
  <div class="alert alert-danger">
    <?php echo $this->session->flashdata('error_msg'); ?>
  </div> 
<?php } ?>

    I want to filter data with both area and cluter and then type and stage also.

    Edit: **

    For more details, I'm adding Controller and model code here:

        $sub_array[] = $row->property_ASYS_no;
        $sub_array[] = $row->property_address_1;
        // $sub_array[] = $row->area;
        $sub_array[] = $row->cluster;
        $sub_array[] = $row->stage;
        $sub_array[] = $row->landlord;
        $sub_array[] = $row->rooms;

            }
        }


        // $sub_array[] = '<a style="text-decoration: none;" href="'.base_url('Property/propertyDetails/'.$row->property_id).'" class="btn-warning btn-xs">View</a>&nbsp;
        // <a style="text-decoration: none;" href="'.base_url('Property/viewRoom/'.$row->property_id).'" class="btn-success btn-xs">Rooms</a>';


        $data[] = $sub_array;
    }

    $output = array(
        "draw" => intval($_POST["draw"]),
        "recordsTotal" => $this->pm->prop_all_data(),
        "recordsFiltered" => $this->pm->prop_filtered_data(),
        "data" => $data
    );

    echo json_encode($output);
}

    I'm gone through this link Data-Tables, But it gives result from columns from table only, I'm not showing area column in the table.

    Edit_2:

    While googled, I got this link, Search API (regular expressions), Data table specific column filter with multi select drop down , Individual column searching (select inputs) , I'm trying to achieve result like this, But with Drop-down box.

    Any kind of help is welcome. Thanks in advance.
