Assign the row column values to the Zend_View instance. The variables assigned to the Zend_View object become the properties of the Zend_View object.

$view->id = $_POST['id'];
$view->journal = $rowset[0]["JOURNAL"];
$view->publisher = $rowset[0]["PUBLISHER"];
$view->edition = $rowset[0]["EDITION"];
$view->title = $rowset[0]["TITLE"];
$view->author = $rowset[0]["AUTHOR"];

Create a view script, resultView.php, associated with the Zend_View object. The view script will run in the scope of the Zend_View object. References to $this in the view script are references to the Zend_View object. Create a table header and add values to the table using the Zend_View properties assigned in the action controller. In the selectAction function render the resultView.php script.

echo $view->render('resultView.php');

Invoke the selectView.php view script with the URL http://localhost/views/selectView.php. Specify the catalog ID for the row that is to be retrieved and click select.

Selecting a database table row

The row corresponding to the specified catalog ID will be retrieved and the results displayed.

Update a Row

Next, update a catalog table row using the Zend Framework. Create an associative array, $data, of column names and values for the row to be updated. Create a SQL expression specifying the WHERE clause for the ID of the row to be updated.

$where[] = "ID ="."'".$_POST['id']."'";

Update the database table using the update() method.

$n = $db->update('Catalog', $data, $where);

Invoke the updateView.php script with URL http://localhost/views/updateView.php. Specify the catalog ID of the row to be updated and the column values to be updated and click on update.

Updating database table

A table row may be deleted using the delete() function.

MVC has a proven track record in simplifying the development and on-going maintenance of applications. Using Zend and the methodology I have outlined, you can now take advantage of MVC to simplify your work with PHP applications.®
