Hai everyone!

I have lots of question about u'r book Thomas. Despite lot's of error inside of it, i have to say this is a really nice book.

I have a couple of question if you don't mind Thomas.

1. I can't click any link from the shopping sample code, until I change the config.php, and the value $config['index_page'] = ""; and use the index.php inside it. Why this happen?

2. Cannot login into the dasbord. I manage to login, after I change the autoload helper autoload.php and remove security in it. $autoload['helper'] = array('url','form','text','date',''); and remove this entry from models madmins.php

Quote:

//$this->db->where('username',db_clean($u,16));
//$this->db->where('password', db_clean(dohash($pw),16));

Can you explain to me?

3. In the admin pages home, on the Full Path collumn i keep getting error "
A PHP Error was encountered

Quote:

Severity: Notice

Message: Undefined index: category_id

Filename: views/admin_pages_home.php

Line Number: 22

i really stuck in this, can you give a hand? I have attach the view (admin_pages_home.php), controller (pages.php) and models (mcats.php).

Sory for my bad english. English not my primary language :)
Thanks before i really need u'r help.

Hi guys, I'm working with langithitam via email as I suspect I'll need to dig through his config and setup. When I get it all straightened out, I'll post here.

For #3, please use code on page 243. I think I sent the publisher the wrong file for admin_pages_home.php, so the ZIP is incorrect. Not sure how that happened. Will remediate as soon as I can.

For login, the original code hash the pw using SHA1 and use the first 16 letters.
So I suggest you put back the code as original.
Then go to http://www.whatsmyip.org/hash_generator/, and copy and paste the first 16letters of SHA1 into password for admin in admins table in your database.

Then try it again.

Regarding #3.
The following is the code for admin_page_home.php I use to show the path.

Code:

<h1><?php echo $title;?></h1>
<p><?php echo anchor("admin/pages/create", "Create new page");?></p>
<?php
if ($this->session->flashdata('message')){
	echo "<div class='message'>".$this->session->flashdata('message')."</div>";
}

if (count($pages)){
	echo "<table border='1' cellspacing='0' cellpadding='3' width='600'>\n";
	echo "<tr valign='top'>\n";
	echo "<th>ID</th>\n<th>Name</th><th>Full Path</th><th>Status</th><th>Actions</th>\n";
	echo "</tr>\n";
	foreach ($pages as $key => $list){
		echo "<tr valign='top'>\n";
		echo "<td>".$list['id']."</td>\n";
		echo "<td>".$list['name']."</td>\n";
		echo "<td>";
   		if (!preg_match("/\.html$/",$list['path'])){
  			$list['path'] .= ".html";
  		}		
		
		if ($list['category_id'] == 0){
			echo "/". $list['path'];
		}else{
			echo "/". $cats[$list['category_id']]. "/". $list['path'];
		}
		echo "</td>";
		echo "<td align='center'>".$list['status']."</td>\n";
		echo "<td align='center'>";
		echo anchor('admin/pages/edit/'.$list['id'],'edit');
		echo " | ";
		echo anchor('admin/pages/delete/'.$list['id'],'delete');
		echo "</td>\n";
		echo "</tr>\n";
	}
	echo "</table>";
}
?>
