 Posted: Mon Mar 16, 2009 1:40 pm Post subject: Unknown DataSource driver |
 |
|
hello all,
I just tested a mdb2 example and everything was right,
now I am following a another simple example using mdb2 combined with datagrid but it fails in datagrid->bind method raising the message “Unknown DataSource driver. Please specify an existing driver” which lead me to think that datagrid not know what data driver I intent to use or it is not where it is supposed to be,
| Code: | <?php
require_once 'DataGrid/DataGrid.php';
// Instantiate the DataGrid
$datagrid =& new Structures_DataGrid();
// Print error if any
if (PEAR::isError($test)) {
echo "Structures_DataGrid ";
echo $datagrid ->getMessage();
exit();
}
// Bind a basic SQL statement as datasource
$options = array('dsn' => 'mysql://username:password@hosturl/databasename');
$test = $datagrid->bind('SELECT id, cc, descripcion FROM tbl_pgc_espanol LIMIT 10', $options);
// Print binding error if any
if (PEAR::isError($test)) {
echo "binding ";
die($test->getMessage());
}
// Print the DataGrid with the default renderer (HTML Table)
$test = $datagrid->render();
// Print rendering error if any
if (PEAR::isError($test)) {
echo "rendering ";
die($test->getMessage());
}
?>
|
please take note that I am not installing pear on server I am just copying php folders and files into my web space directory, it is the only way i know to run pear in that server,
how datagrid knows where to find datasource binding code?,
thank you in advance. |

| Your require_once call indicates that your directories are not correct. DataGrid.php should be in a directory named "Structures", not in "DataGrid". |

thank you for your suggestion mark but i changed the folder name and require_once references accordingly but the error remains,
for more details below i copy the pear folders i copied in the web space folder in order to someone could detect some misleading folder or file into (if any),
thanks in advance,

Please don't try to be smarter than the PEAR installer is.  It's always a good idea to use it, at least for the initial local installation. (Just copying the files to the webserver from the local harddisk is fine in most cases.)
| Code: |
Structures/DataSource
Structures/DataSource/MDB2.php
|
need to be
| Code: |
Structures/DataGrid/DataSource
Structures/DataGrid/DataSource/MDB2.php
|
The same holds for the Renderer directory. |
