早上好
当我尝试执行以下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 $output;
我认为我在以下方面有问题:
<?php'. if ($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,但是由于某些原因,我仍然遇到错误。
PS:对不起,如果我的代码不干净,我在粘贴到此处之前尝试对其进行清理,但是由于某种原因,它不遵循该格式。
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>

<?php if ($row_message['status']) : ?>

<?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 ; ?>

您可以打印带有回显的HTML,但不能打印PHP,因为这是由浏览器解释的
您的代码应为
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;
对不起,我的英语不好。

您的输出中有一个未关闭的php标记,并且您错过了endif
那应该是以下代码:
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 $output;
但是您应该查看the Heredoc syntax,使用这种语法,您的代码将是:
while($row = mysqli_fetch_array($result)) {
$output .= <<<HTML
<tr>
<td>{$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>{$row['headset']}</td>
HTML;
if ($row['status']) {
$output .= '
<td>' . $row['status'] . '</td>';
} else {
$output .= <<<HTML
<td>
<form method="post" action="update-request-status.php">
<input type="hidden" name="reqnumber" value="{$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>
HTML;
}
}
echo $output;
更具可读性,减少了出错的风险,...
