These are values returned from an auto-complete textbox in a successful response from the external program:
| Code Block |
|---|
{
"success": true,
"response": {
"results": [
{
"PNAME": "QUEST BOREAL",
"PRID": "523"
},
{
"PNAME": "QUEST ECLIPSE",
"PRID": "524"
},
{
"PNAME": "QUEST EQUINOX",
"PRID": "525"

This example is JSON information returned when the script encounters an error with an external program driven auto-complete.
| Code Block |

{
"success": false,
"errorId": "08001",
"errorText": "Authorization failure on distributed database connection attempt. SQLCODE=-30082"
}

Full PHP Script Example:

<?php
define("MAX", 10);
define("DB", "S100450A");
define("USER", "user");
define("PASS", "password");
$records = array();
$query = "";
$limit = 0;
if (isset($_REQUEST["query"])) $query = $_REQUEST["query"];
if (isset($_REQUEST["limit"])) $limit = intval($_REQUEST["limit"]);
if ($query != "") {
$query = strtoupper($query) . "%";
if ($limit == 0 || $limit > MAX) $limit = MAX;
// Example of error reporting.
$con = db2_connect(DB, USER, PASS, array("i5_naming" => DB2_I5_NAMING_ON));
if (!$con) {
$response = array(
"success" => false,
"errorId" => db2_conn_error(),
"errorText" => db2_conn_errormsg()
);
print json_encode($response);
return;
}
// The following will not be error checked, for brevity.
$stm = "select distinct pname, prid from rpgspcart/prodp where pname like ? order by pname";
$stm = db2_prepare($con, $stm);
db2_bind_param($stm, 1, "query", DB2_PARAM_IN, DB2_CHAR);
db2_execute($stm);
$count = 0;
while (db2_fetch_row($stm) && $count < $limit) {
$record = array();
$record["PNAME"] = trim(db2_result($stm, "PNAME"));
$record["PRID"] = trim(db2_result($stm, "PRID"));
$records[$count++] = $record;
}
}
// "colWidths" is optional, this helps the widget to
// size the columns when multiple fields are displayed.
$return = array(
"success" => true,
"response" => array (
"results" => $records,
"colWidths" => array(
db2_field_precision($stm, "PNAME"),
db2_field_precision($stm, "PRID")
)
)
);
print json_encode($return);
?>

For example, to make each record display as a block with 2 lines that display one field each, the "results template" property could be set to the following:
| Code Block | ||
|---|---|---|
| ||
<div class="autocomplete-item">
<div class="autocomplete-col"><strong>Label one:</strong> (MYFIELD)</div>
<div class="autocomplete-col"><strong>Label two:</strong> (MYFIELD2)</div>
</div>
