How to retrieve this variable?

[mike12255]

I have a variable $form in the code below what I cant figure out how do it is call it and get the information it has out so I can display the errors:

 

function login($subuser, $subpass, $subremember){
      global $database, $form;  //The database and form object

      /* Username error checking */
      $field = "user";  //Use field name for username
      if(!$subuser || strlen($subuser = trim($subuser)) == 0){
         $form->setError($field, "* Username not entered");
      }
      else{
         /* Check if username is not alphanumeric */
         if(!preg_match("^([0-9a-z])*$^i", $subuser)){
            $form->setError($field, "* Username not alphanumeric");
         }
      }
      
      if ($database->usernameBanned($subuser))
      {
      	$form->setError($field, "*Your Account has been banned");
      }

      /* Password error checking */
      $field = "pass";  //Use field name for password
      if(!$subpass){
         $form->setError($field, "* Password not entered");
      }
      
      /* Return if form errors exist */
      if($form->num_errors > 0){
         return false;
      }

      /* Checks that username is in database and password is correct */
      $subuser = stripslashes($subuser);
      $result = $database->confirmUserPass($subuser, md5($subpass));

      /* Check error codes */
      if($result == 1){
         $field = "user";
         $form->setError($field, "* Username not found");
      }
      else if($result == 2){
         $field = "pass";
         $form->setError($field, "* Invalid password");
      }
      
      /* Return if form errors exist */
      if($form->num_errors > 0){
         return false;
      }

You will need to look at your form class and see what setError() is doing with the error data that is passed to it.

Sorry Ment to attach it, here it is:

* field values that were entered correctly.

class Form
{
   var $values = array();  //Holds submitted form field values
   var $errors = array();  //Holds submitted form error messages
   var $num_errors;   //The number of errors in submitted form

   /* Class constructor */
   function Form(){
      /**
       * Get form value and error arrays, used when there
       * is an error with a user-submitted form.
       */
      if(isset($_SESSION['value_array']) && isset($_SESSION['error_array'])){
         $this->values = $_SESSION['value_array'];
         $this->errors = $_SESSION['error_array'];
         $this->num_errors = count($this->errors);

         unset($_SESSION['value_array']);
         unset($_SESSION['error_array']);
      }
      else{
         $this->num_errors = 0;
      }
   }

   /**
    * setValue - Records the value typed into the given
    * form field by the user.
    */
   function setValue($field, $value){
      $this->values[$field] = $value;
   }

   /**
    * setError - Records new form error given the form
    * field name and the error message attached to it.
    */
   function setError($field, $errmsg){
      $this->errors[$field] = $errmsg;
      $this->num_errors = count($this->errors);
   }

   /**
    * value - Returns the value attached to the given
    * field, if none exists, the empty string is returned.
    */
   function value($field){
      if(array_key_exists($field,$this->values)){
         return htmlspecialchars(stripslashes($this->values[$field]));
      }else{
         return "";
      }
   }

   /**
    * error - Returns the error message attached to the
    * given field, if none exists, the empty string is returned.
    */
   function error($field){
      if(array_key_exists($field,$this->errors)){
         return "<font size=\"2\" color=\"#ff0000\">".$this->errors[$field]."</font>";
      }else{
         return "";
      }
   }

   /* getErrorArray - Returns the array of error messages */
   function getErrorArray(){
      return $this->errors;
   }
};

?>

 

I assumed it would be something like $errors = getErrorArray(); echo $errors[0] but I couldnt get it to work either  lol gonna keep trying though

[Buddski]

$form->errors

echo '<pre>' , print_r($form->errors,true) , '</pre>';

[mike12255]

yeah I tried the errors thing as well since it says its an array of the errors but I couldnt figure out how to access that array there is one element so I tried

 

echo $form->errors[0] and echo $form->errors(0)

 

btw your code output:

 

Array
(
    [user] => *Your Account has been banned
)

[Buddski]

The errors array is not stored with numeric keys, that is why it was failing.

oh ok so I access it via user i take it, thanks.

 

Thanks a lot for guiding me through this.
