happy new years function error...

[prezident]

if(!is_array($e))
{
    $fulldisp = 1;
    $e = array('title' => 'No Entries Yet',
               'entry' => '<a href="../admin.php">Post an entry!</a>'
             );
        }
    }
    // Add the $fulldisp flag to the end of the array
    array_push($e, $fulldisp);
    
    return $e;
}

can someone please tell me why I'm getting this notice ?

Notice: Undefined variable: e in /var/www/blog/inc/functions.inc.php on line 40

is the $e is declared before checking is_array($e)...that might be the error...

<?php
function retrieveEntries($db, $id=NULL){
    if(isset($id))
    {
        $sql = "SELECT title, entry
                FROM entries
                WHERE id=?
                LIMIT 1";
        $stmt = $db->prepare($sql);
        $stmt->execute(array($_GET['id']));
        $e = $stmt -> fetch(); 
               $fulldisp = 1;
    }
    else
    {
        $sql = "SELECT id, title
                FROM entries
                ORDER BY created DESC";
            foreach($db->query($sql) as $row){
            $e[] = array('id' => $row['id'],
                         'title' => $row['title']
                         );
            }
        $fulldisp = 0;
if(!is_array($e))
{
    $fulldisp = 1;
    $e = array('title' => 'No Entries Yet',
               'entry' => '<a href="./admin.php">Post an entry!</a>'
             );
        }
    }
    array_push($e, $fulldisp);
    return $e;
}
function sanitizeData($data){
    if(!is_array($data))
    {
               return strip_tags($data, "<a>");
    }
    else{
         return array_map('sanitizeData', $data);
    }
}
?>

Maybe it's the database not saving my entry to the array because when i click save my entries don't save here is the update code...

<?php
//if the full display flag is set, show the entry
if($fulldisp==1)

{

    ?>
            <h2> <?php echo $e['title'] ?> </h2>
            <p>  <?php echo $e['entry'] ?> </p>
            <p class="backlink"><a href="./">Back to Latest Entries</a>
            </p>
<?php

} //end the if statement

//if the full display flag is 0, format linked entry title
else{
    //loop through each entry
    foreach($e as $entry){

?>
            <p>
                <a href="?id=<?php echo $entry['id'] ?>">
                <?php echo $entry['title'] ?>
                
                </a>
            </p>
<?php

    } //end the foreach loop 
} //end the else 
            
?>
                <p class="backlink"><a href="/admin.php">Post a New Entry</a>
                </p>
      </div>
</body>
</html>

You need to correctly tab your code so your opening and closing brackets align.  You'll probably see your error that way.  I think:

    array_push($e, $fulldisp);

 

may be the problem.  It's outside the if,then section, meaning it is not checked whether it is an array or not.  Can you tell us which is line 40, the line it errors on?
