Jinput always returns "Array"

[jmdc]

Hello,

I am trying to debug the code above and it always shows me "Array" in form?s top.
I am just trying to echo the value that is inserted into {fichapedagogica___Alunopedagogicaaescolher}.

PHP Code validation:

$jinput = JFactory::getApplication()->input;
$p = $jinput->get('fichapedagogica___Alunopedagogicaaescolher');
echo $p;

This {fichapedagogica___Alunopedagogicaaescolher} element is a databasejoin element.
Any idea why it doesn?t echo the data inserted into this element?

Thank you.

Joins always return arrays. Basically any element type which uses dropdowns, checkboxes or radio buttons will be an array. If it's a single select, like a dropdown, you can just grab the first entry.

So do something like this ...

$p = $jinput->get('fichapedagogica___Alunopedagogicaaescolher');
$p = is_array($p) ? $p[0] : $p;

You could just do $p = $p[0], but it's good to be in the habit of testing if an input is actually an array before accessing it.

BTW, it's usually better to get our form data using $formModel->getElementData('table___element'). If you want the raw data, add a second argument of true.

It works...thank you...
I have put this code:

$db = JFactory::getDBO();
defined('_JEXEC') or die();
$p = $formModel->getElementData('fichapedagogica___Alunopedagogicaaescolher', true);
$p = is_array($p) ? $p[0] : $p;
echo $p;
