Question

我想请求帮助重新创建以下代码。我将page1.php中的表单数据传输到page2.php，其中包含来自page1.php的表单数据。场景是每当变量ddList1大于0时，它将执行下面的代码，在html中显示它。否则，当变量设置为0时，它将隐藏html代码的块

    <?php
        if($_POST["ddList1"] > 0)
         echo $_POST["ddList1"];
    ?>
<table>
                  <tr>
                    <td><?php echo $_POST["ddList1"]; ?></td>
                    <td><?php echo $_POST["ddList1name"]; ?></td>
                    <td><?php echo $_POST["ddList1desc"]; ?></td>
                    <td>
                        <?php
                                $_ddList1 = $_POST["ddList1"];
                                switch ($_ddList1) {
                                    case "1":
                                        echo "<button type=\"button\" class=\"btn btn-info ButtonOne1\" onclick=\"openwindow1();\" aria-label=\"Left Align\"><span class=\"glyphicon glyphicon glyphicon-list-alt\" aria-hidden=\"true\"></span></button>&nbsp;";
                                        break;
                                    case "2":
                                        echo "<button type=\"button\" class=\"btn btn-info ButtonOne1\" onclick=\"openwindow1();\" aria-label=\"Left Align\"><span class=\"glyphicon glyphicon glyphicon-list-alt\" aria-hidden=\"true\"></span></button>&nbsp;";
                                        echo "<button type=\"button\" class=\"btn btn-info ButtonOne1\" onclick=\"openwindow1();\" aria-label=\"Left Align\"><span class=\"glyphicon glyphicon glyphicon-list-alt\" aria-hidden=\"true\"></span></button>&nbsp;";

Answer 2

你的if语句将运行语句echo $ _POST [“ddList1”];因为如果遵循这种格式。

if(expression) 
 statement;

自“echo $ _POST [”ddList1“];”是以下语句，条件将仅适用于此语句。

您可能想尝试以下格式：

<?php 

 if(condition): 
 statement1;
 statement2;
 ...
 ?>
 <h1>HTML code here!<h1>
 <?php endif; ?>

祝你好运！
