Question

虽然很简单，但我似乎无法找到以下内容表单采用某些数据，然后表示表中的数据。

下一步，我点击将我带回表格的超链接现在我的问题是，当再次填写相同的表格时，我是如何才能实现这一目标的，因此两个结果都显示在同一个表格中？然后用数据填写另一个表格会添加另一行，依此类推。

问候。

下面的代码（原谅我不是英文）。

<?php
session_start();
?>

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>
<title>ExpoFormulier</title>

<body>

<?php
if (!empty($_POST))
{
$standnaam = $_POST["standnaam"];
$oppervlakte = $_POST["oppervlakte"];
//value in the form van checkboxes op 1 zetten!
$verdieping = isset($_POST["verdieping"]) ? $_POST["verdieping"] : 0;  //if checkbox    checked value 1 anders 0
$telefoon = isset($_POST["telefoon"]) ? $_POST["telefoon"] : 0;  
$netwerk = isset($_POST["netwerk"]) ? $_POST["netwerk"] : 0; 


if (is_numeric($oppervlakte)) 
{
    $_SESSION["standnaam"]=$standnaam;
    $_SESSION["oppervlakte"]=$oppervlakte;
    $_SESSION["verdieping"]=$verdieping;
    $_SESSION["telefoon"]=$telefoon;
    $_SESSION["netwerk"]=$netwerk;
    header("Location:ExpoOverzicht.php"); //verzenden naar ExpoOverzicht.php dmv header
}
else 
{
    echo "<h1>Foute gegevens, Opnieuw invullen a.u.b</h1>";
}  
}

?>

<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="post" id="form1">
<h1>Vul de gegevens in</h1>
<table>
    <tr>
        <td>Standnaam:</td>
        <td><input type="text" name="standnaam" size="18"/></td>
    </tr>
    <tr>
        <td>Oppervlakte (in m^2):</td>
        <td><input type="text" name="oppervlakte" size="6"/></td>
    </tr>
    <tr>
        <td>Verdieping:</td>
        <td><input type="checkbox" name="verdieping" value="1"/></td>
        <!--value op 1 zetten voor checkbox! indien checked is value 1 -->
    </tr>
    <tr>
        <td>Telefoon:</td>
        <td><input type="checkbox" name="telefoon" value="1"/></td>
    </tr>
    <tr>
        <td>Netwerk:</td>
        <td><input type="checkbox" name="netwerk" value="1"/></td>
    </tr>
    <tr>
        <td><input type="submit" name="verzenden" value="Verzenden"/></td>
    </tr>
</table>

</form>

Answer 1

您的会话变量只会存储输入的最后一段数据。不要将它们作为简单变量存储在会话中，而是尝试在会话中放入一个数组。然后，当再次提交表单时，向这些数组添加另一个条目。这样你就不会覆盖之前的那些。

ETA：

在第1页上，您设置会话变量，请尝试以下方法：

$_SESSION["standnaam"][]=$standnaam;
$_SESSION["oppervlakte"][]=$oppervlakte;
$_SESSION["verdieping"][]=$verdieping;
$_SESSION["telefoon"][]=$telefoon;
$_SESSION["netwerk"][]=$netwerk;

在第2页上，您写出表行，请尝试：

for($i = 0; $i < count($standnaam); $i++) {
    echo "<tr>";     
        echo "<td>".$standnaam[$i]."</td>";
        echo "<td>".$oppervlakte[$i]."</td>";
        echo "<td>".$verdieping[$i]."</td>";
        echo "<td>".$telefoon[$i]."</td>";
        echo "<td>".$netwerk[$i]."</td>";
        echo "<td>".$totalePrijs[$i]."</td>";
    echo "</tr>";
}

我认为应该这样做。

PHP表单：获取结果后，在输入新信息时添加新表行
