Question

我是php的初学者，我正在尝试将此循环保存到数据库，但它只保存数据库的最后一行..我希望有人能提前回答这个问题。

<?php
    $child = $_REQUEST['NumberofChildren'];//requested from the lastpage

    echo "<form method='post' action='familysave.php'>";

    for($n=1; $n<=$child; $n++)

    {
        echo "<table>
        <tr>
        <td><input type='text' name='sibname' placeholder='Fullname' style='width: 150px;' required></td>
        <td><input type='text' name='sibage' placeholder='Age' style='width: 35px;' required></td>
        <td><input type='text' name='sibhea' placeholder='Highest Educational Attainment' style='width: 260px;'></td>
        <td><input type='text' name='sibcs' placeholder='Civil Status' style='width: 100px;' required></td>
        <td><input type='text' name='siboccu' placeholder='Occupation' style='width: 100px;' required></td>
        </tr>       

        </table>";
    }
    ?>
    <input type="submit" value="Save">
    <?php echo "</form>"; 
    ?>

这是familysave.php的代码

    <?php

    $conn = mysql_connect($host, $username, $password);

        if(! $conn)
        {
            die('Could not connect: ' . mysql_error());
        }
    $sibname =$_POST['sibname']
    $sibage =$_POST['sibage']
    $sibhea =$_POST['sibhea']
    $sibcs =$_POST['sibcs']
    $siboccu =$_POST['siboccu']

    $sql = "INSERT INTO $tblname (NameofSiblings, Age, HEA, CivilStatus, Occupation) VALUES     ('$sibname', '$sibage', '$sibhea', '$sibcs', '$siboccu')";
    mysql_select_db($dbname);
    $retval = mysql_query($sql, $conn);

    if(! $retval)
    {
        die('Could not Enter Data:' . mysql_error());
    }

    mysql_close($conn);

    ?>

即使在循环中重复字段集，所有FORM字段也具有相同的名称。将这些名称更新为name='sibname[]'，然后在PHP中运行所有这些名称以获取值。

<强>步骤1：

for($n=1; $n<=$child; $n++)
{
    echo "<table>
    <tr>
    <td><input type='text' name='sibname[]' placeholder='Fullname' style='width: 150px;' required></td>
    <td><input type='text' name='sibage[]' placeholder='Age' style='width: 35px;' required></td>
    <td><input type='text' name='sibhea[]' placeholder='Highest Educational Attainment' style='width: 260px;'></td>
    <td><input type='text' name='sibcs[]' placeholder='Civil Status' style='width: 100px;' required></td>
    <td><input type='text' name='siboccu[]' placeholder='Occupation' style='width: 100px;' required></td>
    </tr>       
    </table>";
}

<强>步骤2：

在表单中添加隐藏字段以指示添加的子项数

<input type="hidden" name="n" value="<?php  echo $child; ?>">

第3步：

现在运行一个循环来获取值

$n=intval($_POST["n"]);
for($i=0;$i<$n;$i++)
{
  $sibname =$_POST['sibname'][$i];    // better to use isset() as well
  $sibage =$_POST['sibage'][$i];
  $sibhea =$_POST['sibhea'][$i];
  $sibcs =$_POST['sibcs'][$i];
  $siboccu =$_POST['siboccu'][$i];
  // Now save these values but do not use the deprecated MySQL API, see the link below.
}
