    <p>I am having difficulties grasping the concept of echoing a variable from a database through php. Instead getting a variable in string format i get an integer. How can i display the category string variable through the select box?</p> <p>here is the info in my database: </p> <pre><code>CREATE TABLE `category` ( `c_id` tinyint(4) not null auto_increment, `category` varchar(30) not null, PRIMARY KEY (`c_id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=5; INSERT INTO `category` (`c_id`, `category`) VALUES ('1', 'Animals &gt;'); INSERT INTO `category` (`c_id`, `category`) VALUES ('2', 'Humans &gt;'); INSERT INTO `category` (`c_id`, `category`) VALUES ('3', 'Technology &gt;'); INSERT INTO `category` (`c_id`, `category`) VALUES ('4', 'Oceans &gt;'); INSERT INTO `category` (`c_id`, `category`) VALUES ('5', 'Desert &gt;'); INSERT INTO `category` (`c_id`, `category`) VALUES ('6', 'Jungles &gt;'); </code></pre> <p>Here is my php: </p> <pre><code>&lt;select name="category" size="6" onChange="autoSubmit();"&gt; &lt;?php //POPULATE DROP DOWN MENU WITH CATEGORIES $conn = new PDO($DSN, $USERNAME, $PASSWORD); $sql = "SELECT * FROM category ORDER BY c_id"; while($row = mysql_fetch_array($categories)) { echo ("&lt;option value=\"$row[c_id]\" " . ($category == $row["c_id"] ? " selected" : "") . "&gt;$row[category]&lt;/option&gt;"); } ?&gt; &lt;option value="1" &lt;?php if($category == 1) echo " selected"; ?&gt;&gt;&lt;? echo $category; ?&gt;&lt;/option&gt; &lt;option value="2" &lt;?php if($category == 2) echo " selected"; ?&gt;&gt;&lt;? echo $category; ?&gt;&lt;/option&gt; &lt;option value="3" &lt;?php if($category == 3) echo " selected"; ?&gt;&gt;&lt;? echo $category; ?&gt;&lt;/option&gt; &lt;option value="4" &lt;?php if($category == 4) echo " selected"; ?&gt;&gt;&lt;? echo $category; ?&gt;&lt;/option&gt; &lt;option value="5" &lt;?php if($category == 5) echo " selected"; ?&gt;&gt;&lt;? echo $category; ?&gt;&lt;/option&gt; &lt;option value="6" &lt;?php if($category == 6) echo " selected"; ?&gt;&gt;&lt;? echo $category; ?&gt;&lt;/option&gt; &lt;/select&gt; </code></pre>

    3. COAhhhh! Loops are your friend! Also, `>` is an html special character, so you need to be escaping your `echo $category;` like `echo htmlspecialchars($category);`.

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.
