Datenbank-export in excel-Datei mit codeigniter

Schritt 1: Holen Sie MySql-Daten in Schlüssel-Wert-paar.

    Array
(
    [14] => Array
        (
            [Name] => Parvez Alam
            [Age] => 21
            [Gender] => Male
        )

    [15] => Array
        (
            [Name] => Shavez Alam
            [Age] => 21
            [Gender] => Male
        )

)

Schritt 2: PHP-code zu bekommen, Optionen zu geben und Kraft zu browser-download-Datei, anstatt Sie anzuzeigen.

if(isset($_POST["ExportType"]))

{

switch($_POST["ExportType"])
{
    case "export-to-excel" :
        //Submission from
        $filename = $_POST["ExportType"] . ".xls";       
        header("Content-Type: application/vnd.ms-excel");
        header("Content-Disposition: attachment; filename=\"$filename\"");
        ExportFile($data);
        //$_POST["ExportType"] = '';
        exit();
    default :
        die("Unknown action : ".$_POST["action"]);
        break;
}

}

function ExportFile($records) {
    $heading = false;
        if(!empty($records))
          foreach($records as $row) {
            if(!$heading) {
              //display field/column names as a first row
              echo implode("\t", array_keys($row)) . "\n";
              $heading = true;
            }
            echo implode("\t", array_values($row)) . "\n";
          }
        exit;
}

Schritt 3: Definieren Sie die html-layout für die Anzeige der Daten in Tabelle und-Taste, um Feuer-export-to-csv-Aktion.

<div><a href="javascript:void(0)" id="export-to-excel">Export to excel</a></div>


<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" id="export-form">
                        <input type="hidden" value='' id='hidden-type' name='ExportType'/>
                      </form>
                  <table id="" class="table table-striped table-bordered">
                    <tr>
                        <th>Name</th>
                        <th>Status</th>
                        <th>Priority</th>
                        <th>Salary</th>
                  </tr>
                <tbody>
                  <?php foreach($data as $row):?>
                  <tr>
                  <td><?php echo $row ['Name']?></td>
                  <td><?php echo $row ['Status']?></td>
                  <td><?php echo $row ['Priority']?></td>
                  <td><?php echo $row ['Salary']?></td>
                  </tr>
                  <?php endforeach; ?>
                </tbody>
              </table>

Schritt 4: Nun werden wir nutzen jQuery-code, um zu bekommen, klicken Sie auf Ereignis.

    <script  type="text/javascript">
$(document).ready(function() {
jQuery('#Export to excel').bind("click", function() {
var target = $(this).attr('id');
switch(target) {
    case 'export-to-excel' :
    $('#hidden-type').val(target);
    //alert($('#hidden-type').val());
    $('#export-form').submit();
    $('#hidden-type').val('');
    break
}
});
    });
</script>
