    <p>I have some code that LIMITs data to display only 4 items per page. The column I'm using has about 20-30 items, so I need to make those spread out across the pages. </p> <p>On the first page, I have:</p> <pre><code> $result = mysqli_query($con,"SELECT * FROM menuitem LIMIT 4"); { echo "&lt;tr&gt;"; echo "&lt;td align='center'&gt;&lt;img src=\"" . $row['picturepath'] . "\" /&gt;&lt;/td&gt;"; echo "&lt;td align='center'&gt;" . $row['name'] . "&lt;/td&gt; &lt;td align='center'&gt; &lt;input type='button' value='More Info'; onclick=\"window.location='more_info.php?';\"&gt; &lt;/td&gt;"; echo "&lt;td align='center'&gt;" . $row['price'] . "&lt;/td&gt; &lt;td align='center'&gt; &lt;input type='button' value='Add to Order' onclick=''&gt; &lt;/td&gt;"; echo "&lt;/tr&gt;"; } echo "&lt;/table&gt;"; mysqli_close($con); ?&gt; &lt;table width="1024" align="center" &gt; &lt;tr height="50"&gt;&lt;/tr&gt; &lt;tr&gt; &lt;td width="80%" align="right"&gt; &lt;a href="itempage2.php"&gt;NEXT&lt;/a&gt; &lt;/td&gt; &lt;td width="20%" align="right"&gt; &lt;a href=""&gt;MAIN MENU&lt;/a&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p>You'll notice towards the bottom of the page my anchor tag within lists the second page, "itempage2.php". In item page 2, I have the same code, except my select statement lists the offset of 4.</p> <pre><code>$result = mysqli_query($con,"SELECT * FROM menuitem LIMIT 4 offset 4"); </code></pre> <p>This works, this way when there is a pre-determined number of items within my database. But it's not that good. I need to create a new page only if there are more items, not hard-coded into it like it is now. </p> <p>How can I create multiple pages without having to hard-code each new page, and offset?</p>

    1. COUsing $_GET at the top. If no $_GET, offset is 0. Limit could be hardcoded as a pagination system (for ex. 10 items per page)

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.
