自动选择<select><options>标签

数据我有一个用户填写并击中形式“保存&下一步”，这将带他们到另一个页面，用户可以上传图片，并点击“提交最终”。他们还可以回到以前的页面编辑数据。自动选择<select><options>标签

当时，所有他以前填补了数据应在文本框中显示。我使用会话变量来存储数据并显示它。

我卡在下拉框中。

<select name="District"> 
     <option value="East">East</option> 
     <option value="West">West</option> 
     <option value="North">North</option> 
     <option value="South">South</option> 
</select>

当用户提交，我在会议$_SESSION['District'] = $_POST['District'];存储选择的值，当用户点击回走的前一页，我需要自动选择在下拉菜单中该选项的值了。

我该如何做到这一点？在会议上，如果设置attibute比赛

使用array会更容易。

<?php 
$options = array(
    'East', 'West', 'North', 'South', 
); 
?> 
<select name="District"> 
    <?php foreach($options as $option) { ?> 
     <option value="<?php echo $option; ?>" <?php echo (isset($_SESSION['District']) && $_SESSION['District'] == $option) ? "selected" : "" ?>><?php echo $option; ?></option> 
    <?php } ?> 
</select>

只是检查对一个存储在会话中选择的值。您的选项将是这样的：

<option value="East" <?php echo ($_SESSION['District']=="East" ? "selected" : ""; ?>>East</option>

而且

<select name="District"> 
     <option value="East" <?php echo ($_SESSION['District'] == "East") ? "selected" : "" ?>>East</option> 
     <option value="West" <?php echo ($_SESSION['District'] == "West") ? "selected" : "" ?>>West</option>
