Question

我不知道为什么我的html表单没有发送数据。我有3个名为default.php，prosesbacasoal.php和bacasoal.php的文件。因为default.php太长了，所以我只想写一下我从inspect element

获得的html表单

<form method="post" action="prosesbacasoal.php"><div class="head-main-   recenttest-result">
<input type="hidden" name="nomor" value="2">
<button class="head-main-recenttest-result-wait" style="text-decoration:none;" type="submit" name="submit">2.Soal Kedua</button> </div></form>

prosesbacasoal.php

 <?php
session_start();
if(isset($_POST['submit'])) {
if(isset($_POST['nomor'])) {
$_SESSION['submitsoal'] = true;
$_SESSION['nomorsoal'] = $_POST['nomor'];
header("Location:bacasoal.php");
exit;
} else {
header("Location:bacasoal.php");
exit;
}
} else {
header("Location:bacasoal.php");
exit;
}
?>

bacasoal.php也太长了所以我只写了它的一部分：

<?php
session_start();
if(isset($_SESSION['submitsoal'])) {
if(isset($_SESSION['nomorsoal'])) {
$nomorsoal = $_SESSION['nomorsoal'];
$queryjudulnya = "SELECT nomorsoal,judul,soal FROM soal WHERE   nomorsoal='".$nomorsoal."'";
$runqueryjudulnya = mysqli_query($konek,$queryjudulnya);
$countqueryjudulnya = mysqli_num_rows($runqueryjudulnya);
if($countqueryjudulnya != 0) {
$assocqueryjudulnya = mysqli_fetch_assoc($runqueryjudulnya);
$juduldatabase = mysqli_real_escape_string($assocqueryjudulnya['judul']);
$soaldatabase = mysqli_real_escape_string($assocqueryjudulnya['soal']);
$nomorsoaldatabase =      mysqli_real_escape_string($assocqueryjudulnya['nomorsoal']);
} else {}
} else {}
} else {}
?>

<?php 
if(isset($juduldatabase) && isset($nomorsoaldatabase)) {
echo "<div class=\"head-main-recent\"> ".$nomorsoaldatabase.$juduldatabase."  </div>";
} else {
echo "<div class=\"head-main-recent\">Judul soal tidak ditemukan!</div>";
}
?>

bacasoal.php保持回显失败声明"Judul soal tidak ditemukan!"

有谁知道为什么？（现场演示：http://english-lesson.16mb.com/）

Answer 1

你可以像下面这样做，这样如果有错误，那么它将显示或至少显示一些有用的信息： -

如default.php： - 的

<form method="post" action="prosesbacasoal.php">
<div class="head-main-recenttest-result">
    <input type="hidden" name="nomor" value="2">
    <button class="head-main-recenttest-result-wait" style="text-decoration:none;" type="submit" name="submit">2.Soal Kedua</button> 
</div>
</form>

prosesbacasoal.php： - 的

<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors',1);
if(isset($_POST['nomor'])) {
$_SESSION['submitsoal'] = 'true';
$_SESSION['nomorsoal'] = $_POST['nomor'];
header("location:bacasoal.php");
exit;
} else {
header("location:default.php");
exit;
}
?>

bacasoal.php： - 的

<?php
session_start();
error_reporting(E_ALL);
ini_set('display_errors',1);
$juduldatabase = '';
$soaldatabase = '';
$nomorsoaldatabase = '';
if(isset($_SESSION['submitsoal']) && isset($_SESSION['nomorsoal'])) {
    $nomorsoal = $_SESSION['nomorsoal'];
    $queryjudulnya = "SELECT nomorsoal,judul,soal FROM soal WHERE   nomorsoal='".$nomorsoal."'";
    echo $queryjudulnya;
    $runqueryjudulnya = mysqli_query($konek,$queryjudulnya);
    if($runqueryjudulnya){
        $countqueryjudulnya = mysqli_num_rows($runqueryjudulnya);
        if($countqueryjudulnya > 0) {
            while($assocqueryjudulnya = mysqli_fetch_assoc($runqueryjudulnya)){
                $juduldatabase = $assocqueryjudulnya['judul'];
                $soaldatabase = $assocqueryjudulnya['soal'];
                $nomorsoaldatabase =  $assocqueryjudulnya['nomorsoal'];
            }
        } else {
            echo "No matching record found";
        }
    }else{
        echo "Query execution failed because of:-".mysqli_error($konek);
    }
}else {
    echo "Session variables are not set";
}
?>
<?php 
if(isset($juduldatabase) && isset($nomorsoaldatabase)) {
echo "<div class="head-main-recent"> ".$nomorsoaldatabase.$juduldatabase."</div>";
} else {
echo "<div class="head-main-recent">Judul soal tidak ditemukan!</div>";
}
?>

注意： - 如果仍然没有错误且没有记录，那么回显查询并在db中手动运行该查询并检查是否有任何记录？

Answer 2

在HTML代码的第3行，我可以在表单标记结束之前看到</div>。我无法在表格标签

之后看到潜水开始标签

<button class="head-main-recenttest-result-wait" style="text-decoration:none;" type="submit" name="submit">2.Soal Kedua</button> </div></form>

替换为

<button class="head-main-recenttest-result-wait" style="text-decoration:none;" type="submit" name="submit">2.Soal Kedua</button></form>

Answer 3

这是php会话问题，在session_destroy（）之后修复了它;它使用logout.php

Html不发送帖子数据到PHP
