php - 在 PHP 代码中应用 HTML 代码 - 语法错误

Question

早上好，

当我尝试执行此代码时遇到语法问题错误:

while($row = mysqli_fetch_array($result))
{
    $output .= '
        <tr>
            <td>'.$row["reqname"].'</td>
            <td>'.$row["month"]."/".$row["day"]."/".$row["year"].'</td>
            <td>'.$row["empname"].'</td>
            <td>'.$row["position"].'</td>
            <td>'.$row["account"].'</td>
            <td>'.$row["platform"].'</td>
            <td>'.$row["processor"].'</td>
            <td>'.$row["ram"].'</td>
            <td>'.$row["monitor"].'</td>
            <td>'.$row["phone"].'</td>
            <td>'.$row["phonetype"].'</td>
            <td>'.$row["headset"].'</td>
            <?php'. if ($row['status']) : .'?>
            <td>'.$row["status"].'</td>
            <?php else : ?>
            <td>
                <form method="post" action="update-request-status.php">
                    <input type="hidden" name="reqnumber" value="<?php echo $row_message['reqnumber']; ?>" />
                    <button class="button" type="submit" name="completed" value=""><span>New Request!</span></button>
                </form>
            </td>
            <td><a href="records.php?reqnumber='.$row['reqnumber'] .'"><i class="fa fa-edit" style="color: black; font-size: 25px;"></i></a></td>
            <td><a href="delete.php?reqnumber='.$row['reqnumber'] .'"><i class="fa fa-trash" style="color: red; font-size: 25px;"></i></a></td>
        </tr>
    ';
}
echo $output;

我认为我遇到了具体的问题:

<?php'. if ($row['status']) : .'?>
                <td>'.$row["status"].'</td>
                <?php else : ?>
                <td>
                    <form method="post" action="update-request-status.php">
                        <input type="hidden" name="reqnumber" value="<?php echo $row_message['reqnumber']; ?>" />
                        <button class="button" type="submit" name="completed" value=""><span>New Request!</span></button>
                    </form>
                </td>

如您所见，我尝试添加 '. 和 .' 来模仿其他代码，但由于某种原因我仍然收到错误。

PS:抱歉，如果我的代码不干净，我尝试在粘贴到此处之前清理它，但由于某种原因它不遵循格式。

编辑:

<tr>
    <td><?php echo $row_message['reqname']; ?></td>
    <td><?php echo $row_message['month']."/".$row_message['day']."/".$row_message['year']; ?></td>
    <td><?php echo $row_message['empname']; ?></td>
    <td><?php echo $row_message['position']; ?></td>
    <td><?php echo $row_message['account']; ?></td>
    <td><?php echo $row_message['platform']; ?></td>
    <td><?php echo $row_message['processor']; ?></td>
    <td><?php echo $row_message['ram']; ?></td>
    <td><?php echo $row_message['monitor']; ?></td>
    <td><?php echo $row_message['phone']; ?></td>
    <td><?php echo $row_message['phonetype']; ?></td>
    <td><?php echo $row_message['headset']; ?></td>
    <?php if ($row_message['status']) : ?>
    <td><?php echo $row_message['status']; ?></td>
    <?php else : ?>
    <td>
        <form method="post" action="update-request-status.php">
            <input type="hidden" name="reqnumber" value="<?php echo $row_message['reqnumber']; ?>" />
            <button class="button" type="submit" name="completed" value=""><span>New Request!</span></button>
        </form>
    </td>
    <?php endif ; ?>
    <td><a href="records.php?reqnumber=<?php echo $row_message['reqnumber']; ?>"><i class="fa fa-edit" style="color: black; font-size: 25px;"></i></a></td>
    <td><a href="delete.php?reqnumber=<?php echo $row_message['reqnumber']; ?>"><i class="fa fa-trash" style="color: red; font-size: 25px;"></i></a></td>
</tr>

您可以使用 echo 打印 HTML，但无法打印 PHP，因为这是由浏览器解释的

你的代码应该是

while($row = mysqli_fetch_array($result))
{
    $output .= '<tr>
                <td>'.$row["reqname"].'</td>
                <td>'.$row["month"]."/".$row["day"]."/".$row["year"].'</td>
                <td>'.$row["empname"].'</td>
                <td>'.$row["position"].'</td>
                <td>'.$row["account"].'</td>
                <td>'.$row["platform"].'</td>
                <td>'.$row["processor"].'</td>
                <td>'.$row["ram"].'</td>
                <td>'.$row["monitor"].'</td>
                <td>'.$row["phone"].'</td>
                <td>'.$row["phonetype"].'</td>
                <td>'.$row["headset"].'</td>';
    if ($row['status']) :
        $output .= '<td>'.$row["status"].'</td> ';
    else:
        $output .= '
                <td>
                    <form method="post" action="update-request-status.php">
                        <input type="hidden" name="reqnumber" value="'.$row_message['reqnumber'].'" />
                        <button class="button" type="submit" name="completed" value=""><span>New Request!</span></button>
                    </form>
                </td>
                <td><a href="records.php?reqnumber='.$row['reqnumber'] .'"><i class="fa fa-edit" style="color: black; font-size: 25px;"></i></a></td>
                <td><a href="delete.php?reqnumber='.$row['reqnumber'] .'"><i class="fa fa-trash" style="color: red; font-size: 25px;"></i></a></td>
            </tr>
        ';
     endif;
}  
echo $output;
