    <p>I'm trying to use PHP and MySQL to automatically update my <code>"Products"</code> page. I use MySQL to store my product's IDs, Product name, price, quantity etc. I need help getting PHP to take the MySQL data and put each ID into a <code>&lt;div&gt;</code> with a specific class.</p> <p>I figured I needed a <code>while()</code> loop to get the array of the data and a <code>foreach()</code> loop to get each instance of the ID, but I am not using the <code>foreach()</code> loop right.</p> <p>Please excuse my mess of coding. I'm trying to get all the concepts down and working before I look for more efficient ways of doing things. Note that the <code>sql2['id']</code> contains more than just one item.</p> <pre><code>&lt;?php mysql_connect('localhost', 'user', 'password'); mysql_select_db('store'); $sql1 = mysql_query(' SELECT c.id, c.name, c.description, c.price, c.quantity, c.itemid, c.imgname, c.position, (SELECT Count(t.id) FROM topics AS t WHERE t.parent = c.id AND t.id2 = 1) AS topics, (SELECT Count(t2.id) FROM topics AS t2 WHERE t2.parent = c.id AND t2.id2 != 1) AS replies FROM categories AS c GROUP BY c.id ORDER BY c.position ASC '); if($sql1 === false){ die(mysql_error()); } while($sql2 = mysql_fetch_array($sql1)){ foreach($sql2['id'] as $value){?&gt; &lt;div class="itemInset"&gt; &lt;p&gt;&lt;?php echo $sql2['name']; ?&gt;&lt;/p&gt; &lt;img src="admin/image/&lt;?php echo $sql2['imgName']; ?&gt;" alt="&lt;?php echo $sql2['imgName']; ?&gt;" /&gt; &lt;/div&gt;&lt;?php } } ?&gt; </code></pre> <p>The categories SQL:</p> <pre><code>CREATE TABLE IF NOT EXISTS `categories` ( `id` smallint(6) NOT NULL, `name` varchar(256) NOT NULL, `description` text NOT NULL, `price` text NOT NULL, `quantity` int(10) NOT NULL, `itemID` text NOT NULL, `cC` text NOT NULL, `imgName` text NOT NULL, `position` smallint(6) NOT NULL, PRIMARY KEY (`id`), KEY `name` (`name`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; </code></pre> <p>And a <code>var_dump()</code>:</p> <pre><code>array(20) { [0]=&gt; string(1) "1" ["id"]=&gt; string(1) "1" [1]=&gt; string(9) "PC" ["name"]=&gt; string(9) "PC" [2]=&gt; string(58) "computer " ["description"]=&gt; string(58) "computer " [3]=&gt; string(6) "150.00" ["price"]=&gt; string(6) "150.00" [4]=&gt; string(4) "1000" ["quantity"]=&gt; string(4) "1000" [5]=&gt; string(8) "PCR-1000" ["itemID"]=&gt; string(8) "PCR-1000" [6]=&gt; string(0) "" ["imgName"]=&gt; string(0) "" [7]=&gt; string(1) "1" ["position"]=&gt; string(1) "1" [8]=&gt; string(1) "0" ["topics"]=&gt; string(1) "0" [9]=&gt; string(1) "0" ["replies"]=&gt; string(1) "0" } </code></pre>

    1. COYour connection constructors look weird?. Just to clarify, your user is called `store` and your database is called `user`?

    3. COMind you I need $sql2['id'] to be equal to multiple values. Which is why I thought of the foreach loop

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.

SQuiL has stopped working due to an internal error.

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