HOW TO export CGridView results to CSV file?

Postby administrator » Apr 10th, '17, 12:38

To implement export feature you have to perform 3 simple steps:

1. Add Export button in view file:

Code: Select all

echo '<a href="listings/export" class="export-data align-right"><b class="icon-export">&nbsp;</b> '.A::t('directory', 'Export').'</a>';

2. Create "export" action in yuor controller:

Code: Select all

 * Export data action handler
public function exportAction()
   Website::prepareBackendAction('edit', 'directory', 'listings/manage');

   $filename = 'listings.csv';
   $output = "\xEF\xBB\xBF";
   $listings = Listings::model()->findAll();
   $headersCount = 0;
   foreach($listings as $listing){
      $fieldsCount = 0;
      // Prepare headers
         foreach($listing as $key => $val){
            if($headersCount++) $output .= ',';
            $output .= ucwords(str_replace('_', ' ', $key));
         $output .= "\n";
      // Prepare records
      foreach($listing as $key => $val){
         if($fieldsCount++) $output .= ',';
         $output .= '"'.$val.'"';
      $output .= "\n";
      A::app()->getRequest()->downloadFile($filename, $output, 'application/csv');         
   }catch(Exception $e){
      $this->_view->errorHeader = A::t('directory', 'Export Error');
      $this->_view->errorText = CWidget::create(
         'CMessage', array('error', A::t('directory', 'An error occurred while exporting operation! Please try again later.'))

3. Create "export" view file (for errors):

Code: Select all

    $this->_activeMenu = 'listings/manage';
    $this->_breadCrumbs = array(
        array('label'=>A::t('directory', 'Modules'), 'url'=>'modules/'),
        array('label'=>A::t('directory', 'Business Directory'), 'url'=>'modules/settings/code/directory'),
        array('label'=>A::t('directory', 'Listings Management'), 'url'=>'listings/manage'),

<h1><?= A::t('directory', 'Listings Management'); ?></h1>
<div class="bloc">
    <div class="sub-title">
        <?= $errorHeader; ?>       
        <a href="listings/manage" class="back-link"><?= A::t('directory', 'Back'); ?></a>
    <div class="content">
        <p style="text-align:center;"><?= $errorText; ?></p>
