    Updates Image doesnt work

    Hi Guys,
    I got a problem with updating images in mysql database wih php form.
    It succesfully inserted the images into the database, but it can't do any updates/changes on the existing image record.

    Thanks


    PHP Code:
    <?
    session_start();
    include("database.php");
    include("login.php");
    $pro_id = $_POST['pro_id'];
    $pro_name = $_POST['pro_name'];
    $pro_cat = $_POST['pro_cat'];
    $pro_desc = $_POST['pro_desc'];
    $pro_price = $_POST['pro_price'];

    if (isset($_POST['edit']))
    {
            $name = $_FILES['myfile']['name'];
            $tmp_name = $_FILES['myfile']['tmp_name'];

        if($name)
            {    
                $location = "image/$name";
                move_uploaded_file($tmp_name, $location);
                $sql = "UPDATE product SET pro_name ='$pro_name', pro_cat ='$pro_cat', pro_desc ='$pro_desc', pro_price ='$pro_price', location ='$location' WHERE pro_id ='$pro_id'";
                $result = mysql_query($sql);
                echo "<br>Product has been Edited.<br><br><br>";
                die();
            }
    }               

    $sql = mysql_query("SELECT * FROM product where user_id = '$_SESSION[user_id]'and pro_cat = '$pro_cat' ORDER  by pro_id ASC")or die(mysql_error());
    while($row = mysql_fetch_array($sql))
    {
    $location = $row[imagelocation];
        ?>
                bla...bla...bla....bla
                bla...bla...bla....bla
                
                <td>
                <? echo"<img src='$location' width ='250' height='250'>"                             
                </td>            
                                
                <TD>Image:</TD>
                <TD><input name='myfile' type='file'></TD>
                </TR><br>     

                <input type='hidden' name='pro_id' maxlength='60' value = '<?php echo $row['pro_id']; ?>'>
                <tr><td colspan='2' align='right'>
                <input type='submit' name='edit' value='Edit Product'>
                </td></tr>
                </table>
                </form>
        <?
    }
    ?>

    Maybe try adding parentheses around the items your updating like this...

    PHP Code:
    $sql "UPDATE product SET (pro_name='$pro_name', pro_cat='$pro_cat', pro_desc='$pro_desc', pro_price='$pro_price', location='$location') WHERE pro_id='$pro_id'"
    It may seem odd that it would fix it, but I've gotten results from it with my own experiences in the past using similar syntax.

    Hope this helps.

    Thumbs up

    If you will add else part as mentioned below. This may work.

    if($name)
    {
    $location = "image/$name";
    move_uploaded_file($tmp_name, $location);
    $sql = "UPDATE product SET pro_name ='$pro_name', pro_cat ='$pro_cat', pro_desc ='$pro_desc', pro_price ='$pro_price', location ='$location' WHERE pro_id ='$pro_id'";
    $result = mysql_query($sql);
    echo "<br>Product has been Edited.<br><br><br>";
    die();
    } else {
    $sql = "UPDATE product SET pro_name ='$pro_name', pro_cat ='$pro_cat', pro_desc ='$pro_desc', pro_price ='$pro_price', location='' WHERE pro_id ='$pro_id'";
    $result = mysql_query($sql);
    echo "<br>Product has been Edited.<br><br><br>";
    die();
    }

    Are you checking if $name is true or if it has a value?
    PHP Code:
    if($name
    versus
    PHP Code:
    if(isset($name)) 
    Or perhaps you are checking that the contents of $name are set and have some value?
    PHP Code:
    if(isset($name) && strlen($name)>0
