Forms: Using 1 input box with 2 names - html

Question

my first post here so hope its not too dumb a question. Im including a search box in my nav bar and I want it to search by product title OR description, is this possible ? The code I have so far is as follows which works fine to search by one field but not two
<div class="search_box">
<form method="post" name="search" id="search" action="../admin/search_box.php">
<input type="submit" name="submit" value="Find" style="float: right" />
<div style="overflow: hidden; padding-right: .5em;">
<input type="text" name="description" style="width:100%;" />
</div>
</form>
</div>
and then for the data processing
<?php
require ('dbconnection.php');
$title = filter_var($_POST["title"], FILTER_SANITIZE_STRING);
$description = filter_var($_POST["description"], FILTER_SANITIZE_STRING);
if (isset($_POST['submit'])) // waits for user to enter data into the form
{
$sql_search_lookup = "SELECT * FROM item WHERE item.description LIKE '%$description%'";
$result=mysqli_query ($link, $sql_search_lookup) or die ('Problem:'.$sql_search_lookup);
if (mysqli_num_rows($result) > 0)
{
while ($row=mysqli_fetch_array($result))
{
?>
<div style="float: left; width: 98%; margin: 10px">
<p>
<div style="float:left; width: 20%;">
<a href="/products_detail.php?itemID=<?php print $row["itemID"]?>">
<img src="../images/products/<?php print $row['img_file_path'];?> " width="150" height="120">
</a>
</div>
<div style="float:left;width: 75%;vertical-align:middle; font-size:14px; padding:1%;">
<?php echo "Title: ". $row['title']?><br>
<?php echo "Description: ".$row['description']?>
</div>
</p>
</div>
<?php }
}
else
{
echo "We cant find what you're looking for sorry";
}
}
?>

Your HTML should be:
<div class="search_box">
<form method="post" name="search" id="search" action="../admin/search_box.php">
<input type="submit" name="submit" value="Find" style="float: right" />
<div style="overflow: hidden; padding-right: .5em;">
<input type="text" name="description" style="width:100%;" />
</div>
</form>
</div>
Your mysql query should be something like:
$sql_search_lookup = "SELECT * FROM item WHERE item.description LIKE '%"+$description+"%' or item.title LIKE '%"+$description+"%'";
