php - Query database on clicking a link -


i'm retrieving products database , listing them in while loop. this

<?php   while($row = mysql_fetch_row($result)){     echo '<div class="product_info">';      echo '<div class="category_product_title"><a href="category-page.php">product</a>';      echo '</div>';       echo '<div   class="category_product_number">#'.$row[0].'('.$row[1].')'.'</div>';//prints id , name      echo '<div class="category_product_description">'.$row[2].'</div>';//prints description      echo '<div class="category_product_price">'.$row[4].'tl</div>';//prints price       echo '<div class="category_details"><a href="productpage2.php">details</a></div>';//the link   list product details     echo '</div>';     echo '</div>';  } ?>

i want able print more details on paticular prodcut when "details" link clicked getting id or name of paticular product , using query database. tried saving id in session variable $_session['id'] = $row[0] since i'm looping through these products, i'm not able id of specific product when clicked. how can this?. i'm confused because of loop. thanks

you can assign different link each 1 of products get variable.
instead of <a href="productpage2.php">details</a>, link point <a href="productpage2.php?id='.$row[0].'">details</a>.

then, on product page productpage2.php, can selected id $_get superglobal array this:

$id = $_get['id'];
