    Tutorial CMS

    HI. I've recently created a tutorial cms (content management system) out of a tutorial. But, whenever I try and create a tutorial, it gives me an error. Not a php error.

    Here's the code:
    Code:
    //tutorials.php
    <?php
    
    //Getting the file db.php which includes our database settings. 
    define( 'DB_PATH'  , "./" );
    require DB_PATH."db.php";
    
    
    //Setting up a variable to request the category which is in the URL
    $request_cat = $_REQUEST['category'];
    
    
    //Displaying an actual tutorial
    if (isset($id)) {
    
    // Updating the views, and grabbing a tutorial based on what id it has.
    $update = mysql_query("UPDATE $mysql_table SET views = views + 1  WHERE id='$id'");
    $result = mysql_query("SELECT * FROM $mysql_table WHERE id='$id'");
    while($row = mysql_fetch_array($result)){
     
      // Template for the tutorial
      echo "

    I'm guessing the problem is in here:
    Code:
      if ($_POST['submit']) {
    
      $name = $_POST['name'];
      $avatar = $_POST['avatar'];
      $category = $_POST['category'];
      $description = $_POST['description'];
      $author = $_POST['author'];
      $email = $_POST['email'];
      $content = $_POST['content'];
      $date = date('m-d-Y');
    
        if (!$name || !$avatar || !$category || !$description || !$author || !$email || !$content) {
        die ('Sorry, a field was left blank.  Check all fields again!');
        }
        else {
        mysql_query("INSERT INTO & #036;mysql_table(id,title,avatar,date,category,description,author,email,content,
    views) VALUES('','$name','$avatar','$date','$category','$description','$author','$email','$content','')") or die('Sorry, it failed');
        echo "Success!  You have added the tutorial <strong>$name</strong> to the category <strong>$category.</strong>
    <br>What would you like to do?<br>
    <a href=\"?act=addnew\">Add  a new tutorial</a> &nbsp; ----&nbsp; 
    <a href=\"?act=view\">Edit / Delete a previous tutorial</a>";
        }
      }
    }
    EDIT: Don't know if this will help but here's the install.php file that isntalled the mySQL:

    Code:
    <title>Installer</title>
    <?php
    
    //Getting the file db.php which includes our database settings. 
    define( 'DB_PATH'  , "./" );
    require DB_PATH."db.php";
    
    //Installing
    mysql_query("
    CREATE TABLE `$mysql_table` (
    `id` tinyint(11) NOT NULL auto_increment,
    `title` text NOT NULL,
    `avatar` text NOT NULL,
    `date` varchar(50) NOT NULL,
    `category` varchar(25) NOT NULL default '',
    `description` text NOT NULL,
    `author` text NOT NULL,
    `email` text NOT NULL,
    `content` text NOT NULL,
    `views` varchar( 30 ) NOT NULL default '0',
    PRIMARY KEY (`ID`)
    ) TYPE=MyISAM AUTO_INCREMENT=1 ;
    ")
    or die('Error, something is wrong.  Please make sure all information is correct and try again.');
    
    echo "Install Complete!  All the tables have been installed, and you are all set!  This file has been deleted for security purposes.  If not, please delete it manually.";
    
    ?>
    Hopefully you understand the code. I really need help on this.

    Sorry for the long code.

    You could have posted which error message you get.
    From the glimpse of it, I noticed one possible error:

    PHP Code:
    mysql_query("INSERT INTO [B]& #036;[/B] 
    Remove the bolded part from your code.
    It's located under your "I'm guessing the problem is in here:".
    If that doesn't correct it, please post which error message you get.

    I see... it wasn't a php/server error, it was the message that the code puts out if the tutorial submission didn't work.



    &#036

    Has anyone else had a problem with the tutorial? As it looks like all the code is wrong. Or you have dont something wrong!

    The original tutorial: http://www.forums.pixel-designz.net/...?showtopic=975

    I've edited it and fixed one error. Then I changed the ouput of the tutorial template. That's where I'm having the problem.

    Here's the PHP source file for tutorials.php:

    <span align=\"right\">Category: <a href=\"tutorials.php?category=".$row['category'].\">".$row['category']."</a></span></td>
    Avoid " whenever possible... they parse slower then '....

    Also try this:
    <span align='right'>Category: <a href=\"tutorials.php?category=$row['category']\">$row['category']</a></span></td>
