    <p>Really hoping someone can help me with this. I'm building a PHP / MySQL search form that, hopefully, will allow users to search our wine database and filter the results according to a range of prices selected via a drop down menu. </p> <p>The form works fine searching for, and returning, a nice list of accurate results. But it does NOT price filter the results. </p> <p>After days of searching and experimenting, I've mashed together various code snippets to get this far but, overall, PHP is still very much a mystery to me. </p> <p>It's the correct coding and syntax I struggle with.</p> <p>How might I code the PHP posted here to properly integrate the Price Range filter? I suspect my inclusion of "pricerange" in the sql query is way off base.</p> <ul> <li>MySQL Server version: 5.1.65-cll</li> <li>Price column type: decimal(10,2)</li> </ul> <p>Any help would be hugely appreciated. Please check the code blocks below. </p> <p>Thanks a ton!</p> <h2>HTML</h2> <pre><code> &lt;form method="post" action="winesearch.php?go" id="searchform"&gt; &lt;input type="text" size="35" name="user-entry"/&gt; &lt;select name="pricerange" size="1" id="pricerange"&gt; &lt;option value=""&gt;Price Range&amp;nbsp;&lt;/option&gt; &lt;option value="1"&gt;$&amp;nbsp;10 - $20&lt;/option&gt; &lt;option value="2"&gt;$&amp;nbsp;21 - $30&lt;/option&gt; &lt;option value="3"&gt;$&amp;nbsp;31 - $50&lt;/option&gt; &lt;option value="4"&gt;$&amp;nbsp;51 - $75&lt;/option&gt; &lt;option value="5"&gt;$&amp;nbsp;76 - $100&lt;/option&gt; &lt;option value="6"&gt;$101 - $200&lt;/option&gt; &lt;option value="7"&gt;$201 - Plus&lt;/option&gt; &lt;/select&gt; &lt;input type="submit" name="submit" value="Wine Search"/&gt; &lt;/form&gt; </code></pre> <h2>PHP</h2> <pre><code>&lt;?php if(isset($_POST['submit'])){ if(isset($_GET['go'])){ if(preg_match("/^[a-zA-Z0-9]+/", $_POST['user-entry'])){ $cob=$_POST['user-entry']; $pricerange=$_POST['pricerange']; //connect to the database $db=mysql_connect ("server", "user", "pass") or die (mysql_error()); //-select the database to use $mydb=mysql_select_db("db_name"); if($pricerange == 0) $pricerange = 1; switch ($pricerange) { case 1 : $pricerange = " where Price BETWEEN 10.00 AND 20.00 "; break; case 2 : $pricerange = " where Price BETWEEN 21.00 AND 30.00 "; break; case 3 : $pricerange = " where Price BETWEEN 31.00 AND 50.00 "; break; case 4 : $pricerange = " where Price BETWEEN 51.00 AND 75.00 "; break; case 5 : $pricerange = " where Price BETWEEN 76.00 AND 100.00 "; break; case 6 : $pricerange = " where Price BETWEEN 101.00 AND 200.00 "; break; case 7 : $pricerange = " where Price &gt; 200.00 "; break; } //-query the database table $sql=" SELECT ID, CSPC, Country, Producer, Wine, Year, Price FROM winecellar WHERE CSPC LIKE '%" . $cob .

    1. COWhat doesn't work exactly? Do you know exactly what SQL statement you have built? Have you printed the `$sql` that you have built before executing it?

    3. COIf the size of your products is relatively small I would consider removing the price range from the search feature. Then list all, and add a jquery table sorter on your results. Then the user can sort based on your table headers. Also, currently you display the results in an unordered list, might reconsider that as well.

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.
