將多維數組保存到mysql數據庫中

Question

我正在開發一個在線時間跟蹤網頁。但我堅持將數據傳輸到數據庫的部分。

<?php 
 
\t /* This loop will iterate through all days. */ 
 
\t foreach($_POST["startTime"] as $day=>$startTimes){ 
 
\t /* This loop will give start & end times for a particular day, i.e. $day */ 
 
\t \t \t \t \t 
 
\t foreach($startTimes as $timeIndex=>$startTime){ 
 
\t \t $endTime = $_POST["endTime"][$day][$timeIndex]; 
 

 
\t \t if (mysqli_connect_errno($con)) { 
 
\t \t \t \t echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
 
\t \t \t } else { 
 
\t \t \t \t $sql = "INSERT INTO timetableschedule (name, day, startTime, endTime) ". 
 
\t \t \t \t \t \t "VALUES ('$name', '$day', '$startTime', '![enter image description here][1]$endTime')"; 
 
\t \t \t \t 
 
\t \t \t \t \t \t if (!mysqli_query($con, $sql)) { 
 
\t \t \t \t \t \t \t die('Error: ' . mysqli_error($con)); 
 
\t \t \t \t \t \t } 
 
\t \t \t \t \t \t echo "1 record added"; 
 
\t \t \t \t \t \t mysqli_close($con); 
 
\t \t  } 
 
\t  }   
 
    } \t \t \t \t \t 
 

 
\t \t \t \t ?>

的形式是這樣的，

<table id="dataTable" class="form-control"> 
 
         \t <label for="Monday">Monday</label> 
 
    \t \t \t \t \t \t <input type="button" value="Add Schedule" onClick="addRow('dataTable')" /> 
 
          <tbody> 
 
          <tr>

數據庫應該是這樣的，

但唯一的數據的第一行設法進入數據庫。我不確定當我的php代碼出錯的時候。

Answer 1

更改您的HTML這個

    <td> 
          <label>Start Time</label> 
          <input type="text" class="form-control" name="time[0]['start']"> 
         </td> 
         <td> 
          <label>End Time</label> 
          <input type="text" class="form-control" name="time[0]['end']"> 
         </td> 

休息指數將

time[1]['start'] 
time[1]['end'] 

等

那麼你的PHP代碼會更容易閱讀

foreach($_POST['time'] as $day => $time) { 
     $sql = "INSERT INTO timetableschedule (name, day, startTime, endTime) ". 
         "VALUES ('$name', '$day', '" . $time['start'] . "', '" . $time['end'] . "')"; 
}
