php - Joomla 2.5 MVC Model prepareTable function -

while developing mvc component, i'm faced following problem: before saving posted data default.php, data should revised, if necessary. know far, protected function preparetable(&$table) in specific model should cover need. started simple approach, follows:

protected function preparetable(&$table){  $table=$this->gettable();  $table->image="helloworld";  } 

my expectation is, after submitting template specific field in table has value "helloworld", isn't.

perhaps, give me advice how handle preparetable() function?

thank you

if else setup correctly preparetable(&$table) method has table object passed it.

generally preparetable() in class wouldn't gettable(), replace $table being passed in has row data bound it. replacing decouple work done.

i remove line method looks like:

protected function preparetable(&$table){      $table->image="helloworld";  } 

if @ simplest implementation of preparetable() in joomla core files, in com_banners see similar method;

/**  * prepare , sanitise table data prior saving.  *  * @param   jtable  jtable object.  * @since   1.6  */ protected function preparetable(&$table) {     $table->name = htmlspecialchars_decode($table->name, ent_quotes); }
