I'm trying to create a drop down list that populates a <select>
with options pulled from a DISTINCT
argument. Code looks like this:
function cityData() {
$db =& JFactory::getDBO();
$query = "SELECT DISTINCT MSTCITY FROM " . $db->nameQuote('#__mls') . " ORDER BY MSTCITY;";
$db->setQuery($query);
$tbl = $db->loadObjectList();
echo $tbl;
}
Now, I have two views: one is RAW for an AJAX call and the other is the default view. I figured the simplest way would be to just use the default view and do it in PHP, since the default view wasn't really being used for much anyway. So I added a function:
function dropList($tpl = null){
$model = &$this->getModel();
$array = $model->cityData();
$this->assignRef('array', $array );
parent::display($tpl);
}
And then a call in the page
<?php
$thing = $this->array;
echo $thing;
?>
Nothing is being displayed for the echo $thing;
. In the past, when I used PHP to build content instead of AJAX, this worked fine. I don't know if it's using loadObjectList()
that's not giving me anything or what. I know the mySQL query works, as it's be tested in the cmd and I get the result I expect.
In order to debug and see the array values you need to use print_r. In your case edit the default.php file to
<?php
$thing = $this->array;
print_r($thing);
?>
You can also use var_dump
