Question

我的程序运行方式有问题。情况是我有一个表格要求提供日期，然后当点击按钮提交时，将显示具有相同日期的记录。之后有一个按钮提取，如果我点击它，结果将导出为CSV文件。

这是我的代码：

 <html>
        <h1> TC/GC Per Sales Frequency Bracket </h1>
            <body>
            <?php   
                $df = $_POST['df'];
                $dt = $_POST['dt'];
                $db = 'mds_reports';

                if($connect = mysql_connect("172.16.8.32", "mds_reports", "password"))
                $connect = mysql_select_db($db);
                    else die ("Unable to connect".mysql_error());

                echo '<form action = "TCFrequencyBracket.php" method = "post">';
                echo '<table>';

                echo '<tr><td>Date From :</td><td><input name = "df" type = "text" /></td></tr>';
                echo '<tr><td>Date To :</td><td><input name = "dt" type = "text" /></td></tr>';
                echo '<tr><td><input name = "submit" type = "submit" id = "submit" value = "submit"/></td></tr>';
                echo '</table>';
                echo '</div>';
                echo '</div>';
                echo '</form>';

                if (isset($_POST['submit']))
                {
                    echo '<table border = "1" cellspacing = "1">';
                    echo '<th>Restaurant Code</th>';
                    echo '<th>Restaurant Name</th>';
                    echo '<th>100 & BELOW</th>';
                    echo '<th>101-200</th>';

                    echo '<th>301-400</th>';
                    echo '<th>401-500</th>';
                    echo '<th>501-600</th>';
                    echo '<th>601-700</th>';
                    echo '<th>701-800</th>';
                    echo '<th>801-900</th>';
                    echo '<th>901-1000</th>';
                    echo '<th>1001 & ABOVE</th>';

                    $out .= $_POST['extract'];

                    $filename = $file."_".date("Y-m-d_H-i",time());

                    print stripslashes($out);

                    exit;


                }
            ?>
        </body>
</html>`

现在错误是当我尝试打开程序时，即使主页面尚未显示，也已显示提示。此外，文件的内容是代码而不是结果。

Answer 1

我真的不明白这个问题，但我看到了一些问题：

我没有看到任何文件写入。
您的$out变量会获得按钮的值$_POST['extract']，该值始终为extract，仅此而已。

Answer 2

您必须检查为PHP启用设置的Web服务器。将页面本身作为内容获取的一种方法是在服务器未设置为运行PHP时。然后服务器会提示下载页面而不是运行/执行它。

在解决代码问题之前，请确保您的Web服务器可以正确地提供PHP脚本或文件。

接下来看一下如何存储包含文件的给定代码并检查其扩展名是否为.php。

然后检查您在主页中如何包含该页面或如何访问该页面。

导出查询结果
