Error from PHP file

Post by vikas »

Hi Plum team

I am having 2 issues using PHP script with VXML. Below is the PHP section of the code.

[1] the "VXML Validator" tool complains at line "echo "<?xml version=\"1.0\"?>\n";". However this line I had copied from one of the examples I found on plum voice forum.
Error ->
"This document is not valid VoiceXML!
Error on line 43: Start tag expected, '<' not found. "

[2] Later in vxml code I am using below 2 lines to use the variables assigned in PHP section. However getting an error which says that "<" is not allowed within "expr". Can you please check and confirm?

<assign name="IVR_Name" expr="'<?= $name_db ?>'"/>
<assign name="environmentType" expr="'<?= $env_db ?>'"/>

Code: Select all

header('Content-type: text/xml');
require '/home/ec2-user/vendor/autoload.php';


use Aws\DynamoDb\Exception\DynamoDbException;
use Aws\DynamoDb\Marshaler;

$sdk = new Aws\Sdk([
    'endpoint'   => 'https://dynamodb.us-west-1.amazonaws.com',
    'region'   => 'us-west-1',
    'version'  => 'latest'

$dynamodb = $sdk->createDynamoDb();
$marshaler = new Marshaler();

$tableName = 'IVR';

$DNIS = '8332866732';

$key = $marshaler->marshalJson('
        "DNIS": "' . $DNIS . '"

$params = [
    'TableName' => $tableName,
    'Key' => $key

try {
    $result = $dynamodb->getItem($params);
    $env_db = $result["Item"]["env"]["S"];
    $name_db = $result["Item"]["name"]["S"];
} catch (DynamoDbException $e) {
    echo "Unable to get item:\n";
    echo $e->getMessage() . "\n";
echo "<?xml version=\"1.0\"?>\n";
<vxml version="2.0">
	<property name="inputmodes" value="dtmf"/>
	<property name="interdigittimeout" value="6s"/>
	<property name="termtimeout" value="5s"/>

Hi Vikas,

Can you send us the URL that you are attempting to get the IVR to load? We'll be able to zero in on the issue more easily that way.
