Class 'JTable' not found - joomla

Question

I am using Joomla 2.5.11 . I have a php file stored in the /public_html/joomtest/components/com_jumi/files which is pasted below.
I have a PHP form which is stored in the same location i.e /public_html/joomtest/components/com_jumi/files.
I want the PHP form to call the PHP script so that an article is created in Joomla. But whenever the PHP script is called, I receive the below error
Fatal error: Class 'JTable' not found
and the line on which Joomla throws error is
$table = JTable::getInstance('Content', 'JTable', array());
PHP script
<?php
$table = JTable::getInstance('Content', 'JTable', array());
$data = array(
'catid' => 8,
'title' => 'SOME TITLE',
'introtext' => 'SOME TEXT',
'fulltext' => 'SOME TEXT',
'state' => 0,
);
if (!$table->bind($data))
{
$this->setError($table->getError());
return false;
}
if (!$table->check())
{
$this->setError($table->getError());
return false;
}
if (!$table->store())
{
$this->setError($table->getError());
return false;
}
?>
</body>
</html>
I tried putting in
require_once('/libraries/joomla/database/table.php');
but this again didnt work. Please help.

Answer 1

You need to define path of table file you want to use. Use the following code for include the specific table. For example:
JTable::addIncludePath(JPATH_SITE.DS.'components'.DS.'com_content'.DS.'tables');
And then call your table like below:
$con_table = JTable::getInstance('Content', 'JTable', array());
Hope this will work. Good Luck.
