Question

如何创建允许多个操作的提交按钮？在这种情况下，我希望按钮添加新数据并使用一个提交按钮打印新数据。

但是，在我的提交按钮上添加onclick="printContent('div1')"后，INSERT查询不起作用。因此，它将打印旧的最新信息，因为没有添加新数据。

的index.php：

<html>
        <?php
            // Turn off all error reporting
            error_reporting(0);

            include 'dbconnect.php';
         ?>
    <head>
     <script>
                // script to print partial information only
                function printContent(el){
                var restorepage = document.body.innerHTML;
                var printcontent = document.getElementById(el).innerHTML;
                document.body.innerHTML = printcontent;
                window.print();
                document.body.innerHTML = restorepage;
        }
    </script>
    </head>

    <body>
    <form method="POST" action="">
          <button name="submit" type="submit" id="printStuff" class="btn v-btn no-three-d" onclick="printContent('div1')">PRINT!</button>
    </form>

      <?php
            if(isset($_POST["submit"])){
               $sql2 = "INSERT INTO Q_postitem (service_ID, created_time, queue_No) 
               SELECT 1, CONVERT_TZ(CURRENT_TIMESTAMP,'+00:00','+8:00'), max(queue_No)+1 FROM Q_postitem WHERE service_ID=1";

               if (mysqli_query($con, $sql2)) {
                  echo "New record created successfully";
                  } else {
                  echo "Error: " . $sql2 . "" . mysqli_error($con);
                  }

                  echo "<br>".$sql2;

             mysqli_close($con);
             } 

      ?>

     <div id="div1" style="display: none;">
      //ECHO NEW ADDED DATA HERE TO PRINT
     </div>

    </body>
    </html>
