    <p>I have created a form where the user can search the database, and the result depends on how the user fills out the form.<br> For example, say I have name, address, city, state, and zip field, and the user fills out name and city fields, the results reflect the input. When the form submits all records are displayed. for this I write this: </p> <pre><code>if(isset($_POST['submit'])) { $sql = mysql_query("SELECT * FROM table WHERE name LIKE '%" . $_POST['name'] . "%' OR address LIKE '%" . $_POST['address'] . "%' OR city LIKE '%" . $_POST['city'] . "%' OR state LIKE '%" . $_POST['state'] . "%' OR zip LIKE '%" . $_POST['zip'] . "%'"); } &lt;form method="post" action="&lt;?php $_SERVER['PHP_SELF']; ?&gt;"&gt; &lt;tr&gt; &lt;td&gt;Name:&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="name" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Address:&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="address" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;City:&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="city" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;State:&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="state" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;Zip:&lt;/td&gt; &lt;td&gt;&lt;input type="text" name="zip" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;tr&gt; &lt;td&gt;&amp;nbsp;&lt;/td&gt; &lt;td&gt;&lt;input type="submit" name="submit" value="Search" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/form&gt; &lt;/table&gt; &lt;?php if(isset($_POST['submit'])) { while($row = mysql_fetch_array($sql)) { echo $row['name'] . "&lt;br /&gt;"; } } ?&gt; </code></pre> <p>But in this case a user may leave a field blank.</p>

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.
