如何从php

Question

我想将表单中的数据插入到数据库中，但它会提供大量错误通知。

Notice: Array to string conversion in C:\xampp\htdocs\thesis\admin\gov_sched_save.php on line 181

很多错误都会在不同的行中注意到。

这是表单结构structure

和表单的代码（只是我发现令人困惑的部分的片段）：

                        <table class="table table-bordered table-striped" style="margin-right:-10px">
                        <thead>
                          <tr>
                            <th>Time</th>
                            <th>M</th>
                            <th>T</th>
                            <th>W</th>
                            <th>Th</th>
                            <th>F</th>

                          </tr>
                        </thead>

                        <?php
               include('dbcon.php');
                $query=mysql_query("select * from time where days='mtwthf' order by time_in")or die(mysql_error());

            while($row=mysql_fetch_array($query)){
                    $id=$row['time_id'];
                    $start=date("h:i a",strtotime($row['time_in']));
                    $end=date("h:i a",strtotime($row['time_out']));
    ?>
                          <tr >
                            <td><?php echo $start."-".$end;?></td>
                            <td><input type="checkbox" id="check" name="m[]" value="<?php echo $id;?>" style="width: 20px; height: 20px;"><input style="width: 150px;" type="text" placeholder="Post Area" name="area[]"></td>

                          </tr>

    <?php }?>   

    </table>    
    </div><!--col end -->
    <button class="btn btn-lg btn-primary" id="daterange-btn" name="submit" type="submit">
                 Save Schedule
                </button>

这是错误来自的php部分。可能是代码故障的根源。 这部分是插入查询：

$th = $_POST['th'];
$f = $_POST['f'];

事情是我不知道我在html表单结构或php方面是错的。我发现它真的很混乱。

数据库中area字段的字段强制存储单词Array。
