PHP code doesn't work out of shape, but it works outside the shape



  • I've made a dependence field with a list, but if these fields are in shape, the second field with the list is not filled. Out works. How do you make the second field with the list filled in uniform?

        <div class="tb"><form><table>
        <tr>
          <th colspan="3" scope="col">Рецепт</th>
        </tr>
        <tr>
          <td width="77" style="text-align: center; font-weight: bold;">Категория</td>
          <td width="144" style="text-align: center; font-weight: bold;">Название</td>
          <td width="209" style="text-align: center; font-weight: bold;">Описание</td>
        </tr>
        <tr>
          <td>
    <?php
    require('connect.php');
    echo '<select name="category" id="category" class="StyleSelectBox" onchange="javascript:category(this.value);return false;">';
    if($_POST["category"]*1)
        echo '<option value="0">- Категория -</option>';
    else
        echo '<option value="0">- Категория -</option>';
    $query = mysqli_query($link,'select * from category where level=1');
    if(mysqli_num_rows($query))
        while($category = mysqli_fetch_array($query))
            if($_POST["category"] == $category["id_category"])
                echo '<option value="'.$category["id_category"].'" selected>'.$category["name"].'</option>';
            else 
                echo '<option value="'.$category["id_category"].'">'.$category["name"].'</option>';
    echo '</select>';
    echo '<br/><select name="category_2" id="category_2" class="StyleSelectBox"></select>';
    ?>
    </td>
          <td><input type="text" name="textfield" id="textfield"></td>
          <td><input type="text" name="textfield2" id="textfield2"></td>
        </tr>
        <tr>
          <td colspan="3"><input type="submit" name="submit2" id="submit2" value="Добавить запись">
            <input type="submit" name="submit3" id="submit3" value="Показать таблицу">
            <input name="submit5" type="submit" id="submit5" value="Отправить"></td>
          </tr>

  • As a matter of fact, have you in index.php in lines 76 and 83

    <b>Notice</b>:  Undefined index: category in <b>X:\xampp\htdocs\cookbook\index.php</b> on line <b>76</b><br />
    <option value="0">- Категория -</option><br />
    <b>Notice</b>:  Undefined index: category in <b>X:\xampp\htdocs\cookbook\index.php</b> on line <b>83</b><br />
    <option value="1">Супы</option><br />
    <b>Notice</b>:  Undefined index: category in <b>X:\xampp\htdocs\cookbook\index.php</b> on line <b>83</b><br />
