Thanks Andy .. you da' man

[Choosing the right framework for me... HELP]

Hello,

 

You did not mention Smarty, but just in case you do consider itr .. don't. I am locked into a situation where it has to be used and I can tell you that it is "garbage" IMHO ..

[Undefined index problem ..]

Hello,

 

I have an interesting problem to solve ..

 

I am setting up a few radio buttons to establish a new or returning user. Using the below code I am getting the buttons to act the way I want them to, however, when no button is selected (I cannot have any "pre-selected" for this app) I get an  "Undefined index: userType" error in addition to my own error message to the user. The "mUserTypes" array is what I am using to load the radio buttons, and my "selected" value is mNeworReturn[user_type].

 

Thanks for any help offered .. Frank

 

 

 

$this->mNeworReturn = array('user_type' =>  ' ');

$this->mUserTypes = array ('New' => 'I am a first time customer, 'Return' => 'I am a returning customer');

 

if (isset ($_POST['Login']))

  {

      $this->mNeworReturn['user_type'] = $_POST['userType'];

 

        if (empty ($_POST['userType']))

            {

                $this->mUserTypeError = 1;

                $this->_mErrors++

              }

     

          }

 

If needed to review this problem, the below is the whole constructor of the class .. Thanks

 

 

 

class CheckoutStep1

{

  // Public stuff

  public $mErrorMessage;

  public $mLinkToLogin;

  public $mLinkToRegisterCustomer;

  public $mEmail = '';

  public $mNeworReturn;

  public $mUserTypes;

  public $mUserTypeError;

  public $mUserError;

 

 

 

  private $_mErrors = 0;

 

  // Class constructor

  public function __construct()

  {

    if (USE_SSL == 'yes' && getenv('HTTPS') != 'on')

      $this->mLinkToLogin =

        Link::Build(str_replace(VIRTUAL_LOCATION, '', getenv('REQUEST_URI')),

                    'https');

    else

      $this->mLinkToLogin =

        Link::Build(str_replace(VIRTUAL_LOCATION, '', getenv('REQUEST_URI')));

 

   

$this->mLinkToStep2 = Link::ToRegisterCustomer();

 

 

$this->mNeworReturn = array('user_type' => '');

$this->mUserTypes = array ('New' => 'I am a first time customer',

    'Return' => 'I am a returning customer');

 

if (isset($_POST['Login']))

{

      $this->mNeworReturn['user_type'] = $_POST['userType'];

 

  if (empty ($_POST['userType']))

      {

        $this->mUserTypeError = 1;

        $this->_mErrors++;

  }

     

}

 

  }

[Can't get data from my variable ..]

I solved my problem by using a table join and sub query in mySQL in order to eliminate the mProdCat variable that was giving me trouble. It is more efficient anyway, but I sure wonder what I was doing wrong with this .. Thanks anyway ..

[Can't get data from my variable ..]

Something else interesting here, when I run the following code:

 

$this->mProdCat = Catalog::GetCategoryByProduct($this->_mProductId);

if (array_key_exists('category_id', $this->mProdCat))

        $this->$mProdSelect =

          (int)$this->mProdCat['category_id'];

      else

        trigger_error('CategoryId not set');

 

$this->mProdCat  reads back as the term Array in my browser .. when I run the query manually:

 

SELECT category_id

  FROM product_category

  WHERE product_id = inProductId;

 

I get the expected result under category_id

 

Can anyone offer anything?

 

Thanks ..

 

Frank

 

[Can't get data from my variable ..]

I have tried casting the result as an int after this statement (becasue this->mProductSize requires an int) but same result. I am a real noob and I suspect that I may need additional processing since mProdCat is a variable (should only contain one number). I do not need to do anything with mProductSize though and it returns a much larger array.

 

Any suggestions on how I may "process further"?  I have tried giving mProductSize things like mProdCat[0] and mprodCat['category_id'] to no avail.

 

Thanks .. Frank

[Can't get data from my variable ..]

This is the varibale that is giving the problem..

 

$this->mProdCat = (int)Catalog::GetCategoryByProduct($this->_mProductId);

 

I am using the return of this as the variable input to the following ..

 

$this->mProductSize = Catalog::GetProdsByCategory($this->mProdCat);

 

I have read (and reread) my typing and verified my typing. and I am still only getting as return of the value 1 from    this->ProdCat  I am stumped..

 

Thanks for the interest ..

[Can't get data from my variable ..]

Hello,

 

I am a real noob here and I am pulling my hair out over this problem ..

 

I have a variable defined and I am only able to get a 1 or 0 value when calling it .. it is only one line, and interestingly, other just like it are working fine. Here is the line ..

 

$this->mProdCat = (int)Catalog::GetCategoryByProduct($this->_mProductId);

 

it is inside a function that is calling to the following ..

 

// Retrieves category id from product id

  public static function GetCategoryByProduct($productId)

  {

    // Build SQL query

    $sql = 'CALL catalog_get_category_by_product(:product_id)';

 

    // Build the parameters array

    $params = array (':product_id' => $productId);

 

// Execute the query and return the results

    return DatabaseHandler::GetAll($sql, $params);

  }

 

Finally, this is how I am using it ..

 

$this->mProductSize = Catalog::GetProdsByCategory($this->mProdCat);

 

Everything seems to be doing what it should except since I get this value of 1 (with varified data), I don't populate the list with the proper data .. This is probably easy for the experts, but me .. well ... Thanks for any help offered ..
