OOP class assigning issue

[strazdinjsh]

would anyone know how to assign the value (value returned by some function in the class) of variable $temp in the class: source looks like:

 

class newRecord{
var $temp = listCat('gallery_menu', 'submenu', 'submenu_id'); ////// this line is not working, does not assign?

	function listCat($table, $submenu, $submenu_id)
	{
	$return = '<select name="'.$submenu_id.'" id="'.$submenu_id.'">';
	$result = mysql_query("SELECT * FROM $table");
	while($row=mysql_fetch_object($result))
		{
		$return = $return.'<option value="'.$row->id.'">'.$row->$submenu.'</option>';
		}
		$return = $return.'</select>';
	return $return;
	}


}

 

if function is used out of the class and used in index.php directly, returns expected value of it (there is no doubts - works ok)

You need to put it within the classes constructor.

 

class newRecord
{
  private $temp = array();

  public function __construct()
  {
    $this->temp = $this->listCat('gallery_menu', 'submenu', 'submenu_id');
  }

  // rest of code.
}

thanks a lot, it works.

 

If it is possible, could you tell me in few words the assigning as array - why? what does _construct do in this case? i apologize i am still newbie.

Sorry, $temp shouldn't be setup as an empty array, because it ends up being a string. That's just a blatant mistake on my part.

 

The __construct() is a method which is called automatically when your class is instantiated.
