POST DATA on Json code for "Autocompleter"

Hi All,
i have this problem:

i'm opening a form passed data POST the string [azienda] (is a number code, on this case: 406)
I'm trying to create a Json code for Autocompleter with this data but it doesn't work.
If i print DATAPOST on a form, works fine, but in Json not.

This is my Json code for autocompleter:

<?php
$cod_azie = $_POST['azienda'];
$db = JFactory::getDbo();
$db->setQuery("SELECT  * FROM xcsri_ana_intranet WHERE
cod_azie = $cod_azie
");
$results = $db->loadObjectList();
foreach($results as $result ){
	if(!empty($form->data['tag']) AND stripos($result->nominativo, $form->data['tag']) === false){
		continue;
	}
	$json[] = array('id' => $result->id, 'text' => $result->nominativo);
}
echo json_encode($json);

Any ideas?

i forget ot say: if i write $cod_azie = 406; it works........

Hi andreasuriani,

You haven't defined $json anywhere - that will give a problem with recent PHP versions. Try

$results = $db->loadObjectList();
$json = array();
. . .

Hi Bob,
sorry to be late😟

I've tried but unfortunately doesn't work.

<?php

$cod_azie = $_POST['cod_azie'];
$db = JFactory::getDbo();
$db->setQuery("SELECT  * FROM xcsri_ana_intranet WHERE cod_azie = '" . $cod_azie . "' AND check_conguagliato IS NULL ORDER BY nominativo ASC");
$results = $db->loadObjectList();
$json = array();

foreach($results as $result ){
	if(!empty($form->data['tag']) AND stripos($result->nominativo, $form->data['tag']) === false){
		continue;
	}
	$json[] = array('id' => $result->codice_fiscale, 'text' => $result->nominativo);
}
echo json_encode($json);

Why?😟

Hi andreasuriani ,

I've no idea, I suggest that you add some debug code to echo out some of your intermediate steps so that you can see exactly what is happening.
