I am using a loop with a form to show products in a table that can be edited. When I click the "edit" button to post the update, I want the changes to show up immediately in the form. Right now, I have to refresh the page to see the changes. How can I get the changes to show immediately after clicking on the "edit" (submit) button? My form for editing product is shown below. echo '<a name="Building Envelope Products"></a>';$sql = "SELECT * FROM products WHERE category='Building Envelope Products' order by id"; $result = @mysql_query($sql); if (!result) { $error = 'Error fetching information';exit();} echo '<table class="building"><tr><caption>Edit Building Envelope Products</caption</tr><tr><th>ID</th><th>CATEGORY</th><th>FAMILY</th><th>FAMILY ID</th><th>SBFM</th><th>NAME</th><th>DESCRIPTION</th><th>COLOR</th><th>WT</th><th>PRICE</th><th>INACT</th><th>PayPal #</th><th>EDIT</th></tr>'; while ($row = mysql_fetch_array($result)) { echo '<form action=" " method="post">'; echo '<tr><td><input type="text" name="id" value = "' . $row['id'] . '" size="9" /></td>'; echo '<td><input type="text" name="category" value = "' . htmlspecialchars($row['category'], ENT_QUOTES, 'UTF-8') . '" size="15" /></td>'; echo '<td><input type="text" name="familyname" value = "' . htmlspecialchars($row['familyname'], ENT_QUOTES, 'UTF-8') . '" size="10" /></td>'; echo '<td><input type="text" name="family_id" value = "' . htmlspecialchars($row['family_id'], ENT_QUOTES, 'UTF-8') . '" size="10" /></td>'; echo '<td><input type="text" name="subfamily_identifier" value = "' . htmlspecialchars($row['subfamily_identifier'], ENT_QUOTES, 'UTF-8') . '" size="5" /></td>'; echo '<td><input type="text" name="name" value = "' . htmlspecialchars($row['name'], ENT_QUOTES, 'UTF-8') . '" size="15" /></td>'; echo '<td><input type="text" name="description" value = "' . htmlspecialchars($row['description'], ENT_QUOTES, 'UTF-8') . '" size="45" /></td>'; echo '<td><input type="text" name="color" value = "' . htmlspecialchars($row['color'], ENT_QUOTES, 'UTF-8') . '" size="5" /></td>'; echo '<td><input type="text" name="weight" value = "' . htmlspecialchars($row['weight'], ENT_QUOTES, 'UTF-8') . '" size="3" /></td>'; echo '<td><input type="text" name="list_price" value = "' . htmlspecialchars($row['list_price'], ENT_QUOTES, 'UTF-8') . '" size="3" /></td>'; echo '<td><input type="text" name="inactive" value = "' . htmlspecialchars($row['inactive'], ENT_QUOTES, 'UTF-8') . '" size="1" /></td>'; echo '<td><input type="text" name="button" value = "' . htmlspecialchars($row['button'], ENT_QUOTES, 'UTF-8') . '" size="15" /></td>'; echo '<td><input type="submit" name="action" value="Edit" /></td>'; if (isset($_POST['id']))$id = $_POST['id']; $familyname = $_POST['familyname']; $subfamily_identifier = $_POST['subfamily_identifier']; $name = $_POST['name']; $description = $_POST['description']; $color = $_POST['color']; $weight = $_POST['weight']; $list_price = $_POST['list_price']; $inactive = $_POST['inactive']; $button = $_POST['button']; $description = mysql_real_escape_string($description); $familyname = mysql_real_escape_string($familyname); $subfamily_identifier = mysql_real_escape_string($subfamily_identifier); $name = mysql_real_escape_string($name); $color = mysql_real_escape_string($color); $weight = mysql_real_escape_string($weight); $list_price = mysql_real_escape_string($list_price); $inactive = mysql_real_escape_string($inactive); $button = mysql_real_escape_string($button); $sql = "UPDATE products SET id = '$id', familyname = '$familyname', subfamily_identifier='$subfamily_identifier', name = '$name', description = '$description', color = '$color', weight = '$weight', list_price = '$list_price', inactive = '$inactive', button = '$button' WHERE id ='$id'"; if (!@mysql_query($sql)) { echo '<p>Error updating product: ' . mysql_error() .

you need to use ajax to submit the form dynamically. http://w3schools.com/ajax and you can use DOM to manipulate the node where it needs update. when user click on edit you will change the content of node using DOM and then send the ajax request to update. if request failed fallback to previous data in that node which is being updated or show some error.
