I have a simple web page with some option tags:
<!DOCTYPE HTML>
<html>
<head>
<title>Test</title>
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js" type="text/javascript"></script>
</head>
<body>
<form>
<label>Seleziona l'ente</label>
<select name="data" id="data">
<option value="PRO - 011142764">COMUNE DI AGLIE'</option>
<option value="PRO - 011120674">COMUNE DI AGRATE CONTURBIA</option>
</select>
<input type="text" name="textfield" id="textfield" />
</form>
<script>
$('#data').change(function() {
$.post("richiesta.php", { value: this.value });
$('#textfield').val(this.value);
});
</script>
</body>
</html>
Here's richiesta.php (called from the $.post function):
<?php
function soldipubblici() {
list($comparto, $ente) = explode("-", $_POST['value'], 2);
$curl_parameters = array(
'codicecomparto' => trim($comparto),
'codiceente' => trim($ente),
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://soldipubblici.gov.it/it/ricerca");
curl_setopt($ch,CURLOPT_POST,true);
curl_setopt($ch,CURLOPT_POSTFIELDS,http_build_query( $curl_parameters ));
curl_setopt($ch,CURLOPT_HTTPHEADER,array (
"Content-Type: application/x-www-form-urlencoded; charset=UTF-8",
"Accept: application/json",
"X-Requested-With: XMLHttpRequest",
));
$output=curl_exec($ch);
curl_close($ch);
}
echo soldipubblici();
?>
Everything works fine. In Firebug I can see the request made from richiesta.php using the data gathered from POST is returned correctly.
I just can't find out how to print the response I see in Firebug on screen (or in the input tag).. I tried something like:
$('#data').change(function() {
$.ajax({
url: 'richiesta.php',
type: 'POST',
dataType: 'json',
data: {value: this.value},
}).done(function ( data ) {
$('#textfield').val(data);
});
});
The request still works but in #textfield I get [object Object], not the JSON.
