Method to bind an associative array or object to the JTable instance. This method only binds properties that are publicly accessible and optionally takes an array of properties to ignore when binding. Binding is the process where values are copied into their equivalently named instance properties (see examples).


bind($from, $ignore=array())
Argument Data type Description Default
$from array or object An associative array or object to be bind to the JTable instance.
$ignore array or string An optional array or space separated list of properties to ignore while binding. array()


boolean (true if bind is successful)

Defined in



jimport( 'joomla.database.table' );

Source Body

function bind( $from, $ignore=array() )
        $fromArray      = is_array( $from );
        $fromObject     = is_object( $from );
        if (!$fromArray && !$fromObject)
                $this->setError( get_class( $this ).'::bind failed. Invalid from argument' );
                return false;
        if (!is_array( $ignore )) {
                $ignore = explode( ' ', $ignore );
        foreach ($this->getProperties() as $k => $v)
                // internal attributes of an object are ignored
                if (!in_array( $k, $ignore ))
                        if ($fromArray && isset( $from[$k] )) {
                                $this->$k = $from[$k];
                        } else if ($fromObject && isset( $from->$k )) {
                                $this->$k = $from->$k;
        return true;

In this example the class TableGreeting corresponds to a table called 'jos_greeting' in the Joomla database.

class TableGreeting extends JTable
   var $id       = null;
   var $greeting = null;
   var $language = null;
   var $_code    = null;
   function __construct( &$db )
	parent::__construct( '#__greeting', 'id', $db );

Now, in the model, create an array of fields/properties to be updated and bind it to the table object:

// Create the array of new/amended fields/properties.
$from = array( 'id'        => 6,
               'greeting'  => 'Nǐ hǎo',
               'language'  => 'Chinese',
               'continent' => 'Asia'
               '_code'     => 'ASC012'
// Specify which columns are to be ignored. This can be a string or an array.
$ignore = 'id';
// Get the table object from the model.
$table = $this->getTable( 'greeting' );
// Bind the array to the table object.
$table->bind( $from, $ignore );
// Show the result of the bind for illustration purposes only.
echo '<pre>';
print_r( $table );
echo '</pre>';

This would result in the following output:

TableGreeting Object
    [id] => 
    [greeting] => Nǐ hǎo
    [language] => Chinese
    [_code] =>

Notice that

  • the 'continent' array entry has not been bound to the table object, since 'continent' is not a property of the object.
  • the 'id' array entry has not been bound to the table object either, since 'id' was on the ignore list.
  • the '_code' array entry has not been bound to the table because it is a private property of the table object (its name begins with an underscore).
