    <p>I'm in a bit of a pickle with freshening up my PHP a bit, it's been about 3 years since I last coded in PHP. Any insights are welcomed! I'll give you as much information as I possibly can to resolve this error so here goes!</p> <p><strong>Files</strong></p> <ul> <li>config.php</li> <li>database.php</li> <li>news.php</li> <li>BLnews.php</li> <li>index.php</li> </ul> <p><strong>Includes</strong></p> <ul> <li>config.php -> news.php</li> <li>database.php -> news.php</li> <li>news.php -> BLnews.php</li> <li>BLnews.php -> index.php</li> </ul> <p>Now the problem with my current code is that the database connection is being made but my database refuses to be selected. The query I have should work but due to my database not getting selected it's kind of annoying to get any data exchange going!</p> <p><strong>config.php</strong></p> <pre><code>&lt;?php $dbhost = "localhost"; $dbuser = "root"; $dbpass = ""; $dbname = "test"; ?&gt; </code></pre> <p><strong>database.php</strong></p> <pre><code>&lt;?php class Database { //------------------------------------------- // Connects to the database //------------------------------------------- function connect() { if (isset($dbhost) &amp;&amp; isset($dbuser) &amp;&amp; isset($dbpass) &amp;&amp; isset($dbname)) { $con = mysql_connect($dbhost, $dbuser, $dbpass) or die("Could not connect: " . mysql_error()); $selected_db = mysql_select_db($dbname, $con) or die("Could not select test DB"); } }// end function connect } // end class Database ?&gt; </code></pre> <p><strong>News.php</strong></p> <pre><code>&lt;?php // include the config file and database class include 'config.php'; include 'database.php'; ... ?&gt; </code></pre> <p><strong>BLnews.php</strong></p> <pre><code>&lt;?php // include the news class include 'news.php'; // create an instance of the Database class and call it $db $db = new Database; $db -&gt; connect(); class BLnews { function getNews() { $sql = "SELECT * FROM news"; if (isset($sql)) { $result = mysql_query($sql) or die("Could not execute query. Reason: " .mysql_error()); } return $result; } ?&gt; </code></pre> <p><strong>index.php</strong></p> <pre><code>&lt;?php ... include 'includes/BLnews.php'; $blNews = new BLnews(); $news = $blNews-&gt;getNews(); ?&gt; ... &lt;?php while($row = mysql_fetch_array($news)) { echo '&lt;div class="post"&gt;'; echo '&lt;h2&gt;&lt;a href="#"&gt; ' . $row["title"] .'&lt;/a&gt;&lt;/h2&gt;'; echo '&lt;p class="post-info"&gt;Posted by &lt;a href="#"&gt; &lt;/a&gt; | &lt;span class="date"&gt; Posted on &lt;a href="#"&gt;' . $row["date"] . '&lt;/a&gt;&lt;/span&gt;&lt;/p&gt;'; echo $row["content"]; echo '&lt;/div&gt;'; } ?&gt; </code></pre> <p>Well this is pretty much everything that should get the information going however due to the mysql_error in <code>$result = mysql_query($sql) or die("Could not execute query. Reason: " .mysql_error());</code> I can see the error and it says: </p> <blockquote> <p>Could not execute query. Reason: No database selected</p> </blockquote> <p>I honestly have no idea why it would not work and I've been fiddling with it for quite some time now. Help is most welcomed and I thank you in advance!</p> <p>Greets</p> <p>Lemon</p>

    1. COSince you've been out of PHP for a little while, you should google PDO.

    2. COSorry but in your database class I don't see where you define vars as $dbhost or $dbuser. In the case you didn't, the if will be always false so you'll neither get a connection nor a die().

    3. CO@AurelioDeRosa: He says that the connection is being made, and if you look in his code, the connection will only be made if those variables are all set.

Querying!

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).
