Question

我正在尝试在会话变量中存储选定的下拉值，每次我打印我在其他页面上使用的变量时，它会向我显示数组的最后一个值，我从中基本上填充了我的下拉列表。这是代码;

<?php $options = array('2CHECKOUT','PAYPAL'); ?>

<select name="payment" style="width:225px;" id ="mySelect">
    <?php foreach($options as $opt) { ?>
        <?php $selected = (isset($_SESSION['payment']) && $opt == $_SESSION['payment']) ? ' SELECTED' : '';
        echo '<option value="'.$opt.'"' .$selected.'>'.$opt.'</option>'; ?>
    <?php } ?>
    <?php error_log("the session var".print_r($_SESSION['payment'])); ?>
</select> </div>

有人能帮助我吗？

将您的代码更改为

<?php $options = array('2CHECKOUT','PAYPAL'); ?>

<div>
<select name="payment" style="width:225px;" id ="mySelect">
    <?php foreach($options as $opt) { ?>
        <?php $selected = (isset($_SESSION['payment']) && $opt == $_SESSION['payment']) ? ' SELECTED' : '';
        echo '<option value="'.$opt.'"' .$selected.'>'.$opt.'</option>'; ?>
    <?php } ?>

</select> 
<?php error_log("the session var".print_r($_SESSION['payment'])); ?>
</div>

会话变量不存储选定的下拉值
