报告生成0的空行

标签： php html mysql

不久前，我编写了一些针对MySQL数据库运行查询的代码，然后遍历结果，将它们放入表格中，然后通过电子邮件发送结果。

最近，我收到了早上的邮件，有一段时间我有一个随机的空行，里面有一个“0”，如下所示：

当我运行查询时，其中没有任何0或空行。数据总是回来干净。所以，我认为这必须以某种方式在我的循环中。我不知道。无论如何......下面是我的if语句：

if ($result_count = $conn->query($sql_count)) {
    while($row = $result_count->fetch_assoc()) {
        $message .= '<tr style="white-space: normal;line-height: normal;font-weight: normal;font-variant: normal;font-style: normal;text-align: start;">
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["number"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["u_name"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["code"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["acode"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["name"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["success"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'
        .$row["comment"].
            '</td>
                  </tr>';
    }
} else {
    echo "No work orders have been entered into the system today.";
}

有人有什么想法吗？如果您需要查看其他任何内容，请告知我们。希望有人能发现我似乎看不到的东西。

修改

我会在这里添加更多内容并希望它能够清除它。所以，今天我又得到了另一份报告，并且还有更多的零行。现在几乎每天都在发生......

如果我运行查询，这是输出：

以下是表格的构建方式：

最后......这是用于生成电子邮件的页面（减去所有CSS）

   <!DOCTYPE html>
   <html>

   <head>
   <title>Daily Report</title>
<meta charset=utf-8>
   </head>

   <body>
    <?php 
    require 'db/spoc_config.php';
    ?>
    <?php

    $conn = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    }

    $sql_count = "
    select number, name, u_name, code, acode, success, comment from forms where Day(date) = Day(CURDATE()) and Month(date) = Month(CURDATE()) and year(date) = YEAR(CURDATE());";
    $result_count = $conn->query($sql_count);
    $count = mysqli_fetch_row($result_count);
    $str_count = implode($count);

    date_default_timezone_set('UTC');
    $today = date('l, jS F Y');
    $week = date('W');
    $to = "someemail@email.com";
    $subject = "WOR: Daily Report " . $today;        
    $heading = "<b>Work Order Daily Report: </b>";

    $message = "<h2>" . $heading . " " . $today . "</h2>"; 
    $message .= '<table>';
    $message .= '
     <thead>
     <tr>
     <th>WO#</th>

     <th>Site</th>
     <th>Airline</th>        
     <th>WO Description</th>
     <th>Status</th>
     <th>Comment</th>
     </tr>
     <tr></tr>
     </thead>
     <tbody>
     ';

     if ($result_count = $conn->query($sql_count)) {
     while($row = $result_count->fetch_assoc()) {
     $message .= '<tr>
      <td>'.$row["number"].'</td>
      <td>'.$row["u_name"].'</td>
      <td>'.$row["code"].'</td>
      <td>'.$row["acode"].'</td>
      <td>'.$row["name"].'</td>
      <td>'.$row["success"].'</td>
      <td>'
      .$row["comment"].
      '</td>
      </tr>';
            }
        } else {
            echo "No work orders have been entered into the system today.";
        }

     $message .= '</tbody></table>';         
     $header = "From:someemail@email.com \r\n";
     $header .= "MIME-Version: 1.0\r\n";
     $header .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

     $retval = mail ($to,$subject,$message,$header,'-fsomeemail@email.com');

     $conn->close();
    ?>

好的......所以我确定数据中有零。所以，显示的是正确的....但我无法弄清楚是什么导致了零。我已经包含在表单页面下面，因为我认为它必须是如何生成的。希望有人能看到问题：

    <?php
require 'db/spoc_config.php';

$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);

if (!$link){
    die('Could not connect due to: ' . mysql_error());
}

$db_selected = mysql_select_db(DB_NAME, $link);

if (!$db_selected){
    die('Can\'t use: ' . DB_NAME . ': ' . mysql_error());
}

$u_name = mysql_real_escape_string($_POST['u_name']);
$name = mysql_real_escape_string($_POST['name']);
$code = mysql_real_escape_string($_POST['code']);
$acode = mysql_real_escape_string($_POST['acode']);

mysql_close();

2 个答案:

答案 0 :(得分：0)

根据我的理解，请尝试以下步骤： -

  1. 检查数据库中提交的数据类型。还请
  2. 检查数据库中的数据是否有空白区域。 在代码中添加修剪
  3. 使用结果集检查返回的总行数。

答案 1 :(得分：0)

您可以将$ message包装在验证if（）：

中 
if($row["number"] && $row["number"] > 0)
{
    $message .= '<tr style="white-space: normal;line-height: normal;font-weight: normal;font-variant: normal;font-style: normal;text-align: start;">
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["number"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["u_name"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["code"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["acode"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["name"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'.$row["success"].'</td>
                  <td style="border-width: 1px;padding: 8px;border-style: solid;border-color: #666666;background-color: #ffffff;display: table-cell;vertical-align: inherit;">'
        .$row["comment"].
            '</td>
                  </tr>';
}
else
{
    // skip this line - do nothing
