SOAP web service not returning any value - php

Question

This is my code :
require_once('library/nusoap/nusoap.php');
$NAMESPACE = 'http://domain.com/';
$server = new nusoap_server();
$server->configureWSDL('cm', $NAMESPACE, 'http://domain.com/webservice.php');
$server->wsdl->addComplexType(
'Contacts',
'complexType',
'struct',
'all',
'',
array(
'contact_pid' => array('name'=>'contact_pid','type'=>'xsd:int'),
'contact_pfname' => array('name'=>'contact_pfname','type'=>'xsd:string'),
'contact_plname' => array('name'=>'contact_plname','type'=>'xsd:string')
)
);
$server->wsdl->addComplexType(
'ContactsArray',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array(
array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:Contacts[]')
),
'tns:Contacts'
);
$server->register(
'fetchAllContacts',
array('auth_user'=>'xsd:string','auth_pass'=>'xsd:string'),
array('return'=>'tns:ContactsArray'),
$NAMESPACE);
function fetchAllContacts($auth_user,$auth_pass)
{
$authenticate_query = "select * from users_master where user_email='".$auth_user."' and user_password='".md5($auth_pass)."' and user_status='1'";
$authenticate_user = mysql_query($authenticate_query) or die(mysql_error());
if(mysql_num_rows($authenticate_user) > 0)
{
$row_data = mysql_fetch_array($authenticate_user);
$select_all_contacts = mysql_query("select * from contacts_master where contact_userid='".$row_data['user_pid']."'") or die(mysql_error());
if(mysql_num_rows($select_all_contacts) > 0)
{
$contact_loop = 0;
while($row_contacts = mysql_fetch_array($select_all_contacts))
{
$contact_array[]['contact_pid'] = $row_contacts['contact_pid'];
$contact_array[]['contact_pfname'] = $row_contacts['contact_pfname'];
$contact_array[]['contact_plname'] = $row_contacts['contact_plname'];
$contact_loop++;
}
return $contact_array;
}
else
{
return array("error" => "No records found!");
}
}
else
{
return array("error" => "Error in authentication!");
}
}
if (!isset($HTTP_RAW_POST_DATA)){
$HTTP_RAW_POST_DATA = file_get_contents('php://input');
}
$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$server->service($HTTP_RAW_POST_DATA);
The problem i am having is that it is not returning anything.

Answer 1

When setting the array-values you arn't using the index.
Changing this:
$contact_array[]['contact_pid'] = $row_contacts['contact_pid'];
$contact_array[]['contact_pfname'] = $row_contacts['contact_pfname'];
$contact_array[]['contact_plname'] = $row_contacts['contact_plname'];
into:
$contact_array[$contact_loop]['contact_pid'] = $row_contacts['contact_pid'];
$contact_array[$contact_loop]['contact_pfname'] = $row_contacts['contact_pfname'];
$contact_array[$contact_loop]['contact_plname'] = $row_contacts['contact_plname'];
should do the trick.
