Hello peole,

I saw that there is a export button that exports the list to xls.
It opens fine in excell, but it is actualy a csv.
When I want to ceate a mailinglist in word and connect to this xls file it gives a error.
I can solve this by rename .xls to .csv.
Is there a way that when I hit the export button, that it saves the list with the extention .csv instead of .xls?

Regards

Ralph

Here's a cheesy way of doing it:

 

In your editor, open Grocery_CRUD.php inside the libraries folder under the applications folder.

 

Proceed to line# 1602. 

 

You will find these last few characters in that line: ".xls";

 

Replace the xls with csv.

 

Save the file and you're good to go.

 

That's it!

 

Regards,

Exporting to CSV instead of XLS can be accomplished several ways. The neater way of doing this is to replace the default grocerycrud action for export using the getState function. Always remember that this procedure works only if you use the datatables theme.

 

step 1 - Insert the code to use the datatables theme.

example:

  $gcrud->set_theme('datatables');

 

step 2 - Insert the code to override using getState. The code is placed between the render and the view.

For example, your code might look like this:

  $output = $gcrud->render();

  $this->load->view('report.php',$output); 

 

Insert getState, adjusting the location of your view:

  $output = $gcrud->render();

  // overriding the export action

  $state = $gcrud->getState();

  $state_info = $gcrud->getStateInfo();

  if($state == 'export')

  {

    // this new function replaces grocerycrud's export action

    $this->export_to_csv($state_info);

  }

  else

  {

    // your view is repositioned to this location

    $this->load->view('report.php',$output); 

  }

 

step 3 - Add these 2 new functions to replace grocerycrud's export function. Copy exactly as is:

public function export_to_csv($state_info = null)

{

$data = $this->get_common_data();

 

$data->order_by  = $this->order_by;

$data->types  = $this->get_field_types();

 

$data->list = $this->get_list();

$data->list = $this->change_list($data->list , $data->types);

$data->list = $this->change_list_add_actions($data->list);

 

$data->total_results = $this->get_total_results();

 

$data->columns  = $this->get_columns();

$data->primary_key  = $this->get_primary_key();

 

@ob_end_clean();

$this->_export_to_csv($data);

}

 

 

protected function _export_to_csv($data)

{

$string_to_export = "";

foreach($data->columns as $column){

$string_to_export .= $column->display_as."\t";

}

$string_to_export .= "\n";

 

foreach($data->list as $num_row => $row){

foreach($data->columns as $column){

$string_to_export .= $this->_trim_export_string($row->{$column->field_name})."\t";

}

$string_to_export .= "\n";

}

 

// Convert to UTF-16LE and Prepend BOM

$string_to_export = "\xFF\xFE" .mb_convert_encoding($string_to_export, 'UTF-16LE', 'UTF-8');

 

$filename = "export-".date("Y-m-d_H:i:s").".csv";

 

header('Content-type: application/vnd.ms-excel;charset=UTF-16LE');

header('Content-Disposition: attachment; filename='.$filename);

header("Cache-Control: no-cache");

echo $string_to_export;

die();

}

 

Then you're done!

Hmm ok, i like the first post better and easyer.
Why use such a bunch of text while you can fix it with changing one line.
The thing is that you dont save a xls file, you are saving a csv file with the extention xls
Try opening a real xls file in notepad, you get rubish,
Try open this export file and you see a readable tab sepperated file.


So why is the second post neater?

Freindly regards Ralph

The second option is for others who are following this thread and want a solution that applies to one particular controller only but don't want to fiddle around with the core grocerycrud files.
