Mysql PHP Update Table Values

Actually I want to change it, but according to the condition the changes do not occur.

All code:

<div class="add"> <center> <span><strong>Карточки</strong></span> <a href="/admin/components/carts/add_carts.php" class="back-element">добавить карточку</a> <div class="form-add"> <form method="post"> <select name="item"> <option value="series">Серия</option> <option value="num">Номер</option> <option value="status">Статус</option> </select> <input type="text" name="find" value="" placeholder="Текст поиска..." class="calc_input"> <input type="submit" name="search" value="Поиск / Все элементы" class="calc_submit"> </form> </div> <br> <? if (isset($_POST["search"])) { $search = trim($_POST["find"]); $item = trim($_POST["item"]); $query = "SELECT * FROM carts WHERE $item LIKE '%$search%' ORDER by id DESC"; // print_r($query); $result = mysql_query($query); echo "<div class='CSSTableGenerator'><table><tr><td>Серия</td><td>Номер</td><td>Открыто</td><td>Закрыто</td><td>Окончание</td><td>Статус</td></tr>"; while ($row = mysql_fetch_array($result)) { echo '<tr> <td><a href="?id=', $row["id"], '">', $row["series"], '</a></td> <td><a href="?id=', $row["id"], '">', $row["num"], '</a></td> <td><a href="?id=', $row["id"], '">', $row["date_start"], '</a></td> <td><a href="?id=', $row["id"], '">', $row["date_finish"], '</a></td> <td><a href="?id=', $row["id"], '">', $row["activity"], '</a></td> <td><a href="?id=', $row["id"], '">', $row["status"], '</a></td> </tr>'; } echo "</table></div><br>"; require($_SERVER['DOCUMENT_ROOT'] . "/admin/main/footer.php"); exit(); } // А это форма редактирования записи if (!empty($_GET["id"])) { $query = "SELECT * FROM carts WHERE id=" . $_GET['id'] . ""; $result = mysql_query($query); $row = mysql_fetch_array($result); } // Добавление if (isset($_POST["insert"])) { $query = "INSERT INTO carts (series,num,date_start,date_finish,date_last_use,status,history,summ) VALUES ('{$_POST['series']}', '{$_POST['num']}', '{$_POST['date_start']}','{$_POST['date_finish']}','{$_POST['date_last_use']}','{$_POST['status']}','{$_POST['history']}')"; mysql_query($query); } //Корректировка if (isset($_POST["edit"])) { $query = "UPDATE carts SET series='{$_POST['series']}',num='{$_POST['num']}',date_start='{$_POST['date_start']}',date_finish='{$_POST['date_finish']}',summ='{$_POST['summ']}',status='{$_POST['status']}',history='{$_POST['history']}' WHERE id='{$_POST['id']}'"; $result = mysql_query($query); unset($row); } //Удаление if (isset($_POST["delete"])) { $query = "DELETE FROM carts WHERE id='{$_POST['id']}'"; mysql_query($query); unset($row); } if (!empty($_GET["id"])) { echo ' <div class="form-add"> <form method="post"><table border="0"> <tr> <td><input style="-moz-user-select: none; -khtml-user-select: none; -webkit-user-select: none" type="text" size=10 value="' . $row["status"] .

Actually update processing code:

  <? $true_activity = strtotime($row["activity"]); $true_start = strtotime($row["date_start"]); if ($true_activity == $true_start) { $row["status"]="Просрочено"; $query = "UPDATE carts SET status='{$_POST['status']}' WHERE id='{$_POST['id']}'"; $result = mysql_query($query); unset($row); } ?>
