Answer 1

让我们来看一下这个观点：

<div class="post-body">
<hr>

<?php echo form_open('/posts/delete/'.$posts['id']);?>
         <?php if($this->session->userdata('user_id')==$posts['user_id']);?>
                <a class="btn btn-default " href="posts/edit/">Edit</a>
                <input type="submit" value="Delete" class="btn btn-danger">

</div>

以下是一些问题：

你的if语句最后有一个分号，这实际上是一个无操作。
您的视图中有两个表单，但只有一个</form>或form_close()来电（并且在评论创建表单之后）。从本质上讲，它归结为无效的HTML;按“提交”按钮将提交第一个表单（因为它从未关闭）。

以下代码解决了这些问题：

<div class="post-body">
    <hr>
    <?php if ($this->session->userdata('user_id') == $posts['user_id']): ?>
        <?= form_open('/posts/delete/' . $posts['id']) ?>
        <a class="btn btn-default" href="/posts/edit/<?= $posts['id'] ?>">Edit</a>
        <input type="submit" value="Delete" class="btn btn-danger">
        <?= form_close() ?>
    <?php endif ?>
</div>
