    <p>I'm trying to learn CodeIgniter, but unfortunately many of the tutorials they list on their wiki are several years old and, based on others' comments, don't work on the newest version of CodeIgniter.</p> <p>I did find one that didn't have any negative comments - on <a href="http://www.ibm.com/developerworks/web/library/wa-codeigniter/index.html#icomments" rel="nofollow">IBM DeveloperWorks</a>- but I can't get it to work. Everything up until the form submit is fine, but after I submit I get a blank page and nothing is sent to the database. </p> <p>How can I test/troubleshoot a database connection in CodeIgniter? I know my settings (as far as host, dbname, username/password, etc.) are correct because I'm using them successfully with a plain vanilla PHP site.</p> <p>Edit to add: alternatively, can anyone point me to a recent beginner tutorial that works with the recent version? I don't need an MVC tutorial; I'm familiar with the design pattern. I just need to learn CodeIgniter.</p> <p>Edit to add database.php file:</p> <pre><code>&lt;?php if ( ! defined('BASEPATH')) exit('No direct script access allowed'); $active_group = "default"; $active_record = TRUE; //$db['default']['hostname'] = "localhost"; $db['default']'hostname'] = "myHostName.powwebmysql.com"; $db['default']['username'] = "myUserName"; $db['default']['password'] = "myPassword"; $db['default']['database'] = "codeigniter"; //yes, database is called codeigniter $db['default']['dbdriver'] = "mysql"; $db['default']['dbprefix'] = ""; $db['default']['pconnect'] = TRUE; $db['default']['db_debug'] = TRUE; $db['default']['cache_on'] = FALSE; $db['default']['cachedir'] = ""; $db['default']['char_set'] = "utf8"; $db['default']['dbcollat'] = "utf8_general_ci"; /* End of file database.php */ /* Location: ./system/application/config/database.php */ </code></pre> <p>EDIT: error message when adding database load to constructor:</p> <pre><code>A PHP Error was encountered Severity: Notice Message: Undefined property: Welcome::$load Filename: controllers/welcome.php Line Number: 6 </code></pre> <p>where line 6 is $this->load->database();</p>

    3. CO@rabidmachine9 - from what I was able to gather from the tutorial, all connections are set up in the application/config/database.php file. I've posted mine above, minus some details.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
