php - Cookie through a form and GET -


i using $_get function carry database field forward throughout form. have come across stumbling block when try pull information database:

<?php $prodname=$_get["q"]; ?>   <h3>product name: <u><?php echo $prodname; ?></u></h3><br />   <?php $con = mysql_connect("localhost","cl49-vogalcms","vogalcms"); if (!$con)    {    die('could not connect: ' . mysql_error());    }    $prodname=$row['prodname'];  $catagory=$row['catagory'];  @mysql_select_db("cl49-xxx",$con)or die('unable select database ln 60:'.mysql_error()); $result=mysql_query("select * products prodname=$prodname")or die('ln 61 :'.mysql_error()); $cnt=$_cookie["count"];   setcookie("user",$myid,time()+10000); mysql_close($con); ?>    <form name="newad" method="post" enctype="multipart/form-data"  action="drtsavepic.php?q=<?php echo"$prodname"; ?>">  <br> <br>    <input type="file" name="image"> <input name="submit" type="submit" value="upload image">    </form>

when run code, following error

ln 61 :you have error in sql syntax; check manual corresponds mysql server version right syntax use near '' @ line 1

can shine light on issue?

try replacing mysql_query("select * products prodname=$prodname")

by 

mysql_query("select * products prodname='".$prodname."'")
