Question

在我的视图页面上使用HMVC的codeigniter项目中，$ class显示不正确。当我尝试查看我的模块时，如果没有列左或右，则应该转到 col-sm-12

出于某种原因，如果没有列左侧或右侧，它应显示 col-sm-9 col-sm-12 。

<?php echo $header; ?>
<div class="container">
  <div class="row"><?php echo $column_left; ?>
    <?php if ($column_left && $column_right) { ?>
    <?php $class = 'col-sm-6'; ?>
    <?php } elseif ($column_left || $column_right) { ?>
    <?php $class = 'col-sm-9'; ?>
    <?php } else { ?>
    <?php $class = 'col-sm-12'; ?>
    <?php } ?>
    <div id="content" class="<?php echo $class; ?>"><?php echo $content_top; ?><?php echo $content_bottom; ?></div>
    <?php echo $column_right; ?></div>
</div>
<?php echo $footer; ?>

如果没有列左列或右列，如何显示col-sm-12？

提前致谢。

添加了控制器

<?php defined('BASEPATH') OR exit('No direct script access allowed');

class Home extends MX_Controller {

public function index() {
    $data['column_left'] = Modules::run('catalog/common/column_left/index');
    $data['column_right'] = Modules::run('catalog/common/column_right/index');
    $data['content_top'] = Modules::run('catalog/common/content_top/index');
    $data['content_bottom'] = Modules::run('catalog/common/content_bottom/index');
    $data['footer'] = Modules::run('catalog/common/footer/index');
    $data['header'] = Modules::run('catalog/common/header/index');

    return $this->load->view('theme/default/template/common/home_view', $data);
}
}

Answer 1

elseif(empty($column_left) || empty($column_right)){ ?>
    <?php $class = 'col-sm-12'; ?>
    <?php } ?>

Answer 2

如果设置了$column_left或$column_right，那么它将永远不会到达最后else部分。只需查看!empty()即可。它将检查值是否为空。

<?php if ($column_left && $column_right) { ?>
<?php $class = 'col-sm-6'; ?>
<?php } elseif (!empty($column_left) || !empty($column_right)) { ?>
<?php $class = 'col-sm-9'; ?>
<?php } else { ?>
<?php $class = 'col-sm-12'; ?>
<?php } ?>

Answer 3

你不需要把那千个php打开和关闭标签。

<?php 
    if (!empty($column_left) && !empty($column_right)) {
        $class = 'col-sm-6'; 
    } elseif (!empty($column_left) || !empty($column_right)) {
        $class = 'col-sm-9';
    } else { 
        $class = 'col-sm-12';
    } 
?>

从此声明中删除返回

return $this->load->view('theme/default/template/common/home_view', $data);

这应该是：

$this->load->view('theme/default/template/common/home_view', $data);

我发现什么问题是最简单的事情我忘记了在我的列上左右添加id

感谢@tiGer的删除回复也帮助了

列左侧模块

<?php if ($modules) { ?>
<column id="column-left" class="col-sm-3 hidden-xs">
  <?php foreach ($modules as $module) { ?>
  <?php echo $module; ?>
  <?php } ?>
</column>
<?php } ?>

专栏

<?php if ($modules) { ?>
<column id="column-right" class="col-sm-3 hidden-xs">
  <?php foreach ($modules as $module) { ?>
  <?php echo $module; ?>
  <?php } ?>
</column>
<?php } ?>
