Question

<?php
echo "<form action='bossconfirm2.php' method='post' name='bossex' onsubmit='blankCheck()' >";

echo "<td><select id='disapprove".$i."' name = 'sel".$i."'>
              <option value = '".$row['LeaveID']."'>Approve</option>
              <option value = '2'>Disapprove</option>
          </select>".$i."</td>";

我的代码与上面的内容类似。我试图将sel + $ i（连接时为sel1）的值传递给php文件bossconfirm2.php。这是我的bossconfirm2.php的代码：

$se11 = $_POST['sel1'];
$se12 = $_POST['sel2'];
$se13 = $_POST['sel3'];
$test = $_POST['test'];

echo "HI<br>";
echo "<br> ".$test."<br>";

echo "Sel 1 <br>".$sel1."Sel 2<br>".$sel2."Sel 3 ".$sel3;

每当我显示$sel1的值时，都不显示任何内容。我放了一个回音“HI
”;看看PHP语法是否有问题，但我发现$_POST[]无法访问表单。我尝试在文件末尾添加一个html语法，看看我是否可以使用此代码将值传递给$test

<td><input type='text' name='test'></td>

它有效。我使用纯PHP（echo ..etc）创建的表单似乎无法传递值。有人请告诉我如何才能使它发挥作用？

编辑：这是我的完整代码

echo "</tr>";
}                 
echo "</form>";


?>
<td><input type='text' name='test'></td>

这是我的bossconfirm.php的代码

<?php
include 'config.php';
include 'opendb.php';
session_start();
$sessionID = $_SESSION['id'];
$x = 0;
$checkValue = $_POST['value'];

$sel1 = $_POST['sel1'];
$sel2 = $_POST['sel2']; 
$sel3 = $_POST['sel3']; 
$test = $_POST['test'];

echo "HI<br>";
echo "<br> " . $test . "<br>";

echo "Sel 1 <br>" . $sel1 . "Sel 2<br>" . $sel2 . "Sel 3 " . $sel3;

$today = date('Y-m-d');
?>

Answer 1

检查发布内容的一种方法是print_r（$ _ POST）函数，它将打印发布值数组。

您还可以将此包装在预标签中，如下所示，以更易读的形式格式化输出，例如

<pre>
<?php print_r($_POST); ?>
</pre>

无法从PHP表单中读取$ _POST []值
