trying to search through sql data shown in php, not working


Hi I have a SQL database which contains information about properties. Above this I have a search button which searches the propertyLocation field to display relevant ones.


Property ID 1, 5 Bedroom House, London Property ID 2, 3 Bedroom House, Scotland Property ID 3, 2 Bedroom Flat, Cardiff.

At the top all i'm trying to do is put a search in which if the user types "london" only property ID 1 will be shown. I cannot seem to get it to work! My code is as follows:

Displaying the properties and search box:

<table id="propertyTable"> <form method="post" action="search.php"> <input type="text" name="search" /> <input type="submit" name="submit" value=" Search "> </form> <th>Property ID</th> <th>Property Name</th> <?php $result = mysql_query("SELECT * FROM Property"); while ($row = mysql_fetch_array($result)) { $pID = $row['pID']; $pLocation = $row['pLocation']; echo "<tr data-row='$pID'><td>$pID</td>"; echo "<td>".$pID."</td>"; echo "<td>".$pLocation."</td>"; } ?> </table>

Search.php code:

<?php $sql="SELECT * FROM Property WHERE pLocation like '$search%'"; $result=mysql_query($sql, $db) or die(mysql_error()); while ($row=mysql_fetch_array($result)) { $pID=$row["pID"]; $pLocation=$row["pLocation"]; } ?>

Please note I am connecting to my DB at the top. The first form does display the properties however, search just does not work.

Any help would be greatly appreciated!


I keep getting errors, Use of undefined constant search and undefined variable DB...

</li> <li>

Errors fixed, it leads to search.php but nothing is displayed! Current search.php code is:

"; echo "".$pID.""; echo "".$pLocation.""; } ?></li> </ul>


You need to get your $search var out of the $_POST array:

$search = $_POST['search'];


Saw your second error about DB. You said: "Please note I am connecting to my DB at the top. " but if you are getting $db undefined, there is an issue with this. Maybe follow the syntax on your other page and use the assumed connection like:

$result=mysql_query($sql) or die(mysql_error());

On the first page there is output echoed. You need to mimic that on your search results:

$pID = $row['pID']; $pLocation = $row['pLocation']; echo "<tr data-row='$pID'>"; echo "<td>".$pID."</td>"; echo "<td>".$pLocation."</td></tr>";

I tried to fix some of the wonky table structure; the first page seemed to output one long row?


Try the following, i.e. initialize the $search variable with the POST value

<?php $search = trim($_POST['search']); $sql="SELECT * FROM Property WHERE pLocation like '$search%'"; $result=mysql_query($sql, $db) or die(mysql_error()); while ($row=mysql_fetch_array($result)) { $pID=$row["pID"]; $pLocation=$row["pLocation"]; } ?>
