Displaying CSV file content in Yii Framework's CGridView - yii

Question

I am trying to display CSV file content in CGridView, I want to display CSV file header as CGridView "Column" and its content as DataProvider. Please provide any idea to achieve this?

You can use CArrayDataProvider.
http://www.yiiframework.com/doc/api/1.1/CArrayDataProvider
$dataProvider = new CArrayDataProvider(str_getcsv(file_get_contents('file.csv')));
You can do something like this.
$file = fopen('test.csv', 'r');
$data = array();
while (($line = fgetcsv($file)) !== FALSE) {
//$line is an array of the csv elements
$data[] = $line;
}
fclose($file);
$columns = array();
foreach ($data[0] as $key => $value) {
$columns[] = array(
'name' => $key,
'header' => $value,
);
}
$data = array_slice($data, 1);
$dataProvider = new CArrayDataProvider($data, array(
'keyField' => 0,
));
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $dataProvider,
'columns' => $columns
));
If you want to create a generic data provider for CSV, you can create a new class.
class CsvDataProvider extends CArrayDataProvider {
private $_columns = array();
public function __construct($file, $config = array()) {
$handler = fopen($file, 'r');
$data = array();
while (($line = fgetcsv($handler)) !== FALSE) {
$data[] = $line;
}
fclose($handler);
$this->_columns = array();
foreach ($data[0] as $key => $value) {
$this->_columns[] = array(
'name' => $key,
'header' => $value,
);
}
$data = array_slice($data, 1);
parent::__construct($data, array_merge($config, array(
'keyField' => 0,
)));
}
public function getColumns() {
return $this->_columns;
}
}
Then you can do something like this.
$dataProvider = new CsvDataProvider('file.csv');
$this->widget('zii.widgets.grid.CGridView', array(
'dataProvider' => $dataProvider,
'columns' => $dataProvider->getColumns(),
));
