[RESOLVED] Passing error message stored in class

[kilbey1]

I'm a bit new to working with classes in PHP. What I'm attempting to do is create some back-end processing, and when an error is returned, store the error and let it display wherever I need it to display.

The basic flow I'm shooting for:
1. edit.php?status=new sets up the empty form
2. process.php calls class newsHandler.php to do some checking and/or insertion
3. if an error occurs, store the error message, return use to edit.php?status=new and display error message

So as an example, we set up a new form on the edit.php page:

case 'new':
		$addnews = new newsHandler;
		$addnews->pageTitle("New Article");
		$oFCKeditor->Value		= '' ;
	break;
....
<form action="process.php" method="post">
			<input name="id" type="hidden" value="<?php echo $_POST['id']; ?>">
			<?php 
			$oFCKeditor->Create() ;
			?>
			<br><br>
			<input type="button" value="Return to Main" onClick="location.href='main.php'">
			<input type="submit" value="Submit">
		</form>

The form posts to process.php. Process.php calls class newsHandler.php addArticle method:

class newsHandler {
	function addArticle($id,$text,$date='') {
		if ( isset( $_POST ) ) {
		   $postArray = &$_POST ;			// 4.1.0 or later, use $_POST
		} else {
		   $postArray = &$HTTP_POST_VARS ;	// prior to 4.1.0, use HTTP_POST_VARS
		}

	foreach ( $postArray as $sForm => $value )
	{
		if ( get_magic_quotes_gpc() ) {
			$postedValue = htmlspecialchars( stripslashes( $value ) ) ;
		} else {
			$postedValue = htmlspecialchars( $value ) ;
		}
	}

	//if date is empty, set it to now
	if($date=='') { $date = strtotime("now"); }

	$data = array(
	   'id' => $id, 
	   'text' => $postedValue,
	   'created_dtm' => $date
	   );

		$database = new db_class;
		$database->connect();
		if (empty($data['text'])) {
			$message[] = "Please enter some text into the editor; we can't allow empty text.<br />";
		} else {
			$insert_data = $database->insert_array(TBL_NEWS, $data);
			if (!$insert_data) {
				$database->print_last_error(false);
				$database->print_last_query();
			} else {
				$message[] = "Article successfully added.<br />";
			}
		}

		foreach($message as $key => $value){
			return $value . "<br />";
		}	
}
}	

Here is process.php in its barest form.

		require_once('../database/constants.php');
		require_once('../database/db.class.php');
		require_once("includes/newsHandler.php");

   $referer = $_SERVER['HTTP_REFERER'];

   if (preg_match("/status=new/i", $referer)) {
		$addnews = new newsHandler;

		$data = $addnews->addArticle('Null',$postedValue,strtotime("now"));

		if($data == false) {
			//$host  = $_SERVER['HTTP_HOST'];
			//$uri   = rtrim(dirname($_SERVER['PHP_SELF']), '/\\');
			//$extra = 'mypage.php';
			//header("Location: http://$host$uri/$extra");
			//exit;

			print_r($_POST);
			echo $message;

			return;
		} else {
				//$addnews->pageTitle("New Article");
		}
  } elseif (preg_match("/status=edit/i", $referer)) {
  		print_r($_POST);
  }

Ok, I learned about $this....very cool. Passing the error array into an error($text) function works nicely, and I can then call error() on my page. My main goal now is to get it to redirect where I need to, and display that error message.

Process.php

...if we have errors, relocate page to last referrer
header("Location: $referer");
exit;

Resulting page:

if(isset($addnews->errors()) {
     $addnews->errors();
}
