如何在使用php的两个按钮提交的表格单元格中保留数据？ 以下是输出：

这是我想要的结果（注意：下面的图像只是使用图像编辑器编辑的）：

这是我使用的代码：

<html>
<head>
<title>Sample </title>
</head>
<body>

<table border = "1" align = "center" cellpadding = "10" >
<form method = "post" action = "<?php echo $_SERVER['PHP_SELF']; ?>">

<tr>
<td>Output1 : 
  <?php 
     if (isset($_POST['run1'])) {
     echo "<b>" .$_POST['input1']. "</b>"; 
     }  
  ?> 
 /td>

<td>Output2 : 
<?php 
   if (isset($_POST['run2'])) {
     echo "<b>" .$_POST['input2']. "</b>"; 
   }
?>
</td>
</tr>

<tr>
<td><input type = "text" name = "input1" value = "Type here..."></td>
<td><input type = "text" name = "input2" value = "Type here..."></td>
</tr>

<tr>
<td align = "center"><input type = "submit" name = "run1" value = "Button 1"></td>
<td align = "center"><input type = "submit" name = "run2" value = "Button 2"> </td>
</tr>

</form>
</table>
</body>

您只需检查其他密钥名称：


 <?php 
     if(!empty($_POST['input1'])) {
        echo "<b>" .$_POST['input1']. "</b>"; 
     }  
  ?> 




编辑：因为您确实想要持久化数据，所以需要一个会话：


<?php
# Start session (don't hide warnings)
session_start();
# Check if content being submitted
if(!empty($_POST['input1']))
    $_SESSION['input1'] = $_POST['input1'];
if(!empty($_POST['input2']))
    $_SESSION['input2'] = $_POST['input2'];
?>
<html>
<head>
<title>Sample </title>
</head>
<body>
<form method = "post" action = "<?php echo $_SERVER['PHP_SELF']; ?>">
    <table border = "1" align = "center" cellpadding = "10" >
        <tr>
            <td>Output1 : 
                <?php 
                if(!empty($_SESSION['input1']))
                    echo "<b>" .htmlspecialchars($_SESSION['input1']). "</b>";
                ?> 
            </td>
            <td>Output2 : 
                <?php 
                if(!empty($_SESSION['input2']))
                    echo "<b>" .htmlspecialchars($_SESSION['input2']). "</b>";
                ?> 
            </td>
        </tr>
        <tr>
            <td>
                <input type = "text" name = "input1" value = "Type here...">
            </td>
            <td>
                <input type = "text" name = "input2" value = "Type here...">
            </td>
        </tr>
        <tr>
            <td align = "center"><input type = "submit" name = "run1" value = "Button 1">
            </td>
            <td align = "center">
                <input type = "submit" name = "run2" value = "Button 2">
            </td>
        </tr>
    </table>

输出2：

可能使用$_SESSION保存数据，即使页面重新加载。将其保存到任何持久性存储：SESSION、cookie、database，因此forthI已经尝试了$_SESSION，但仍然得到相同的结果：（感谢您的回复，但我仍然遇到同样的问题，当我在第一个输入框中键入“Hello 1”，然后单击按钮1时，它会出现在第一列（输出1）但当我在第二个输入框中键入“Hello 2”并点击按钮2时，第二列（输出2）上有一个输出但是第一列中的输出1消失了？谢谢，感谢您的帮助。您是在尝试同时加载它们，还是让用户执行一个、提交、另一个，然后再次提交并同时显示？如果是这样，您必须使用会话来持久化数据。是的，这就是我尝试执行的操作：P 1。在第一个文本框中输入，然后点击按钮n 1，出现在顶部表格单元格（第1列）2。再次在第二个文本框中输入，然后点击按钮2，然后再次出现在顶部表格单元格（第2列）谢谢！那么是的，如果你想在不同的时间单击提交按钮，那么你需要保存到会话，但是你需要在html输出到页面之前完成。顺便问一下，有没有办法清除我输入框中记录的数据？我的意思是，当我重新加载页面时，所有数据都会被清除？这是图片：再次感谢高级：）非常感谢：）感谢您提供另一个解决方案：）
