Hi All,
These days I'm busy with the PHP Photo Gallery Solution.
In this system Admin can upload images and its' descriptions. When user point mouse on the image, tooltip will appear. That tooltip windows contain images' description.
My problem is, Image Details are stored in photos table. And its' description stored in another table called description.
In gallery page, images will appear according to its' category. Now I have to take data from two tables and have to use two while loop.
I tried to do something but I couldnt.
Following I listed my code

if(!empty($_GET['Go']))
{
    $photo_category = $_GET['photo_category'];
    echo "<h3>". $photo_category . "</h3><br><br>";


    $get = mysql_query("SELECT * FROM `photos` WHERE `category`='$photo_category'");
    if(!empty($get))
    {
            while($row = mysql_fetch_array($get)){

        {

            $photoid=$row['id'];

            $get1 = mysql_query("SELCT * FROM `description` WHERE `pid`='$photoid'");
            if(!empty($get1))
            {
                while($row2 = mysql_fetch_array($get1))
                {


    echo '<div id="main_item"> 
             <div class="new_mark"></div>';
    echo '<div id="item_img"><a href="'.$row['link'].'" class="zoom"><img src="photo/'.$row['link'].'" id="img_pen"/></a></div>';
    echo '<div id="item_dis">
            <div class="your_selector">
                          More  <br/>
                                     ';
    echo '<div class="tooltip_description" style="display:none;" title="'.$row[1].'">';

    echo "
    <table id='tool_dis_td' border='0' style='padding:0px; margin:0px'>

    <tr height='5'>
    <td colspan='2'> <p id='top_head'>Gemstone Information</p> </td>
    </tr>

    <tr>
    <td width='140'> Type : </td>
    <td width='260'> ".$row[4]." </td>
    </tr>

    <tr>
    <td> Colour : </td>
    <td> ".$row[5]." </td>
    </tr>

    <tr>
    <td> Origin : </td>
    <td> ".$row[6]." </td>
    </tr>

    <tr>
    <td> App. Carat Weight : </td>
    <td> ".$row[7]." </td>
    </tr>


  </table>";

    echo '</div></div><a href="contact.php"><div class="order_click"> Order Now</div></a></div></div>';
}
}

        }
        }}}
