Description

JTable::load() - Loads a row from the database and binds the fields to the object properties.

Preconditions

JTable is an abstract class. You need to write a child class, to use its functionality. See Part 4 of the MVC Tutorial

Example

Let's say we have a table, that stores greetings of different languages:

id greeting language
1 Hello English
2 Bonjour French
3 Guten Tag German

If we'd like to load the record with the id #3, we can call the table object from within the model, and load the record:

$table = $this->getTable('greeting');
$table->load(3);
echo '<pre>';
print_r($table);
echo '</pre>';
 
/* RETURNS:
TableGreeting Object
(
    [id] => 3
    [greeting] => Guten Tag
    [language] => German
)
 
*/
