Flash Builder 4 and PHP Data/Services for beginners

Question

Hello,
I'm new here, so I do not know if I posted my doubts in the right place.
without much la la la go straight to the point.
I am developing an application in flex / mysql / php / zend DataWizard and used the flex to create the data service.
populei my dropdown with the desired data (cities) and populei my datagrid with their respective data (customer master), so far so good. That's when I came across a difficulty which already makes two weeks and try to solve anything. the little knowledge I have in programming know it's something silly, but I can not solve.
Difficulty: I select a city in my dropdown and display all my customers registered in the same city in my datagrid. simple! I found some tutorials on the net talking about it, did exactly what her boss but unfortunately got no success (not populates the datagrid), may be doing algor be unable to realize. so it follows my code so they can help me. grateful!!
FLEX CODE
/ / Populating DropDownList City
protected function ddl_cidade_cadastro_solutions_creationCompleteHandler(event:FlexEvent):void
getAllMunicipioResult.token = municipioService.getAllMunicipio();
//Populating DataGrid
protected function ddl_cidade_cadastro_solutions_changeHandler(event:IndexChangeEvent):void
txt_recebe_cidade.text = ddl_cidade_cadastro_solutions.selectedItem.Cidade_PJ;
getAllEmpresasResult.token = empresasService.getAllEmpresas(ddl_cidade_cadastro_solutions.selectedItem.Cidade_PJ);
PHP CODE
public function getAllEmpresas($q) {
$stmt = mysqli_prepare($this->connection, "SELECT * FROM $this->tablename WHERE 'Cod_Cidade_PJ' LIKE '%$q%'");
$this->throwExceptionOnError();
mysqli_stmt_execute($stmt);
$this->throwExceptionOnError();
$rows = array();
mysqli_stmt_bind_result($stmt, $row->Codigo, $row->CGC, $row->CEmpresa, $row->NomeFantasia, $row->RazaoSocial, $row->Endereco_PJ, $row->Bairro_PJ, $row->CEP_PJ, $row->Cod_Cidade_PJ, $row->Cidade_PJ, $row->Estado_PJ, $row->TelefoneDDD_PJ, $row->Telefone_PJ, $row->FaxDDD_PJ, $row->Fax_PJ, $row->Email_PJ, $row->RecEmail_PJ, $row->HomePage_PJ, $row->NumFunc, $row->CodPorte, $row->Porte, $row->CodRegiao, $row->Regiao, $row->CodCNAE, $row->CNAE, $row->Produto, $row->ExportaPais, $row->IndustriaSN, $row->AnuncianteSN, $row->RowNumber, $row->negrito);
while (mysqli_stmt_fetch($stmt)) {
$rows[] = $row;
$row = new stdClass();
mysqli_stmt_bind_result($stmt, $row->Codigo, $row->CGC, $row->CEmpresa, $row->NomeFantasia, $row->RazaoSocial, $row->Endereco_PJ, $row->Bairro_PJ, $row->CEP_PJ, $row->Cod_Cidade_PJ, $row->Cidade_PJ, $row->Estado_PJ, $row->TelefoneDDD_PJ, $row->Telefone_PJ, $row->FaxDDD_PJ, $row->Fax_PJ, $row->Email_PJ, $row->RecEmail_PJ, $row->HomePage_PJ, $row->NumFunc, $row->CodPorte, $row->Porte, $row->CodRegiao, $row->Regiao, $row->CodCNAE, $row->CNAE, $row->Produto, $row->ExportaPais, $row->IndustriaSN, $row->AnuncianteSN, $row->RowNumber, $row->negrito);
mysqli_stmt_free_result($stmt);
mysqli_close($this->connection);
return $rows;

Hi,
The first issue will be the pathing differences between wamp/mamp/xampp, some use www as root others htdoc you need to setup the php services on your local machine rather than importing a project.
The created services will have a connection array declared at the top of the code that points to the mysql server, in the project default debug folder you will have the config file that has the zend and webserver path
top of service file
============
var $username = "root";
var $password = "";
var $server = "localhost";
var $port = "3306";
var $databasename = "zend";
var $tablename = "clients";
var $connection;
amfconfig.ini
=========
[zend]
;set the absolute location path of webroot directory, example:
;Windows: C:\apache\www
;MAC/UNIX: /user/apache/www
webroot =C:/wamp/www
;set the absolute location path of zend installation directory, example:
;Windows: C:\apache\PHPFrameworks\ZendFramework\library
;MAC/UNIX: /user/apache/PHPFrameworks/ZendFramework/library
;zend_path =
[zendamf]
amf.production = false
amf.directories[]=Zender-debug/services
In your main project folder you have a .model folder the file there is an *.fml file that contains your channel endpoints etc.
