pbootcms默认只有一个上传图片的地方，响应式模板这种调用，图片是要写在一起的，那么我们要给轮播图片再增加一个上传项要怎么操作呢？

首先到数据库【ay_slide】表中新增一个轮播图字段，假如是【picc】，新增字段如下图：这里配合的是Navicat，操作前记得先备份数据库。

打开/apps/admin/controller/content/SlideContrller.php文件

找到代码：// 轮播图增加，添加【picc】这个新增的数据字段名称，该文件共需要新增四处，可以对照其他字段进行添加

// 轮播图增加
    public function add()
    {
        if ($_POST) {
            // 获取数据
            $gid = post('gid', 'int');
            $pic = post('pic');
            $link = post('link');
            $title = post('title');
            $subtitle = post('subtitle');
            $sorting = post('sorting', 'int');
            
            if (! $gid) {
                $gid = $this->model->getMaxGid() + 1;
            }
            
            if (! $pic) {
                alert_back('图片不能为空！');
            }
            
            // 构建数据
            $data = array(
                'acode' => session('acode'),
                'gid' => $gid,
                'pic' => $pic,
                'link' => $link,
                'title' => $title,
                'subtitle' => $subtitle,
                'sorting' => $sorting,
                'create_user' => session('username'),
                'update_user' => session('username')
            );
            
            // 执行添加
            if ($this->model->addSlide($data)) {
                $this->log('新增轮播图成功！');
                if (! ! $backurl = get('backurl')) {
                    success('新增成功！', base64_decode($backurl));
                } else {
                    success('新增成功！', url('/admin/Slide/index'));
                }
            } else {
                $this->log('新增轮播图失败！');
                error('新增失败！', - 1);
            }
        }
    }

改为

// 轮播图增加
    public function add()
    {
        if ($_POST) {
            // 获取数据
            $gid = post('gid', 'int');
            $pic = post('pic');
            $picc = post('picc');//这里是增加的内容-AB模板网提供
            $link = post('link');
            $title = post('title');
            $subtitle = post('subtitle');
            $sorting = post('sorting', 'int');
            
            if (! $gid) {
                $gid = $this->model->getMaxGid() + 1;
            }
            
            if (! $pic) {
                alert_back('图片不能为空！');
            }
            
            // 构建数据
            $data = array(
                'acode' => session('acode'),
                'gid' => $gid,
                'pic' => $pic,
                'picc' => $picc,
                'link' => $link,
                'title' => $title,
                'subtitle' => $subtitle,
                'sorting' => $sorting,
                'create_user' => session('username'),
                'update_user' => session('username')
            );
            
            // 执行添加
            if ($this->model->addSlide($data)) {
                $this->log('新增轮播图成功！');
                if (! ! $backurl = get('backurl')) {
                    success('新增成功！', base64_decode($backurl));
                } else {
                    success('新增成功！', url('/admin/Slide/index'));
                }
            } else {
                $this->log('新增轮播图失败！');
                error('新增失败！', - 1);
            }
        }
    }

在找到//修改操作

    // 修改操作
    if ($_POST) {
        
        // 获取数据
        $gid = post('gid', 'int');
        $pic = post('pic');
        $link = post('link');
        $title = post('title');
        $subtitle = post('subtitle');
        $sorting = post('sorting', 'int');
        
        if (! $gid) {
            $gid = $this->model->getMaxGid() + 1;
        }
        
        if (! $pic) {
            alert_back('图片不能为空！');
        }
        
        // 构建数据
        $data = array(
            'gid' => $gid,
            'pic' => $pic,
            'link' => $link,
            'title' => $title,
            'subtitle' => $subtitle,
            'sorting' => $sorting,
            'update_user' => session('username')
        );
        
        // 执行添加
        if ($this->model->modSlide($id, $data)) {
            $this->log('修改轮播图' . $id . '成功！');
            if (! ! $backurl = get('backurl')) {
                success('修改成功！', base64_decode($backurl));
            } else {
                success('修改成功！', url('/admin/Slide/index'));
            }
        } else {
            location(- 1);
        }
    } else {
        // 调取修改内容
        $this->assign('mod', true);
        if (! $result = $this->model->getSlide($id)) {
            error('编辑的内容已经不存在！', - 1);
        }
        $this->assign('gids', $this->model->getGid());
        $this->assign('slide', $result);
        $this->display('content/slide.html');
    }
}

改成

    // 修改操作
    if ($_POST) {
        
        // 获取数据
        $gid = post('gid', 'int');
        $pic = post('pic');
        $picc = post('picc');
        $link = post('link');
        $title = post('title');
        $subtitle = post('subtitle');
        $sorting = post('sorting', 'int');
        
        if (! $gid) {
            $gid = $this->model->getMaxGid() + 1;
        }
        
        if (! $pic) {
            alert_back('图片不能为空！');
        }
        
        // 构建数据
        $data = array(
            'gid' => $gid,
            'pic' => $pic,
            'picc' => $picc,
            'link' => $link,
            'title' => $title,
            'subtitle' => $subtitle,
            'sorting' => $sorting,
            'update_user' => session('username')
        );
        
        // 执行添加
        if ($this->model->modSlide($id, $data)) {
            $this->log('修改轮播图' . $id . '成功！');
            if (! ! $backurl = get('backurl')) {
                success('修改成功！', base64_decode($backurl));
            } else {
                success('修改成功！', url('/admin/Slide/index'));
            }
        } else {
            location(- 1);
        }
    } else {
        // 调取修改内容
        $this->assign('mod', true);
        if (! $result = $this->model->getSlide($id)) {
            error('编辑的内容已经不存在！', - 1);
        }
        $this->assign('gids', $this->model->getGid());
        $this->assign('slide', $result);
        $this->display('content/slide.html');
    }
}

然后打开后台模板/apps/admin/view/default/content/slide.html文件

找到

<div class="layui-form-item">
  <label class="layui-form-label">图片</label>
  <div class="layui-input-inline">
    <input type="text" name="pic" id="pic" required  lay-verify="required" placeholder="请上传图片"  class="layui-input">
  </div>
  <button type="button" class="layui-btn upload" data-des="pic"> <i class="layui-icon">&#xe67c;</i>上传图片 </button>
  <div id="pic_box" class="pic"></div>
</div>

在这段代码下面加入下面代码

<div class="layui-form-item">
  <label class="layui-form-label">图片2</label>
  <div class="layui-input-inline">
    <input type="text" name="picc" id="picc" required  lay-verify="required" placeholder="请上传图片2"  class="layui-input">
  </div>
  <button type="button" class="layui-btn upload" data-des="picc"> <i class="layui-icon">&#xe67c;</i>上传图片 </button>
  <div id="pic_box" class="pic"></div>
</div>

再找到

<div class="layui-form-item">
  <label class="layui-form-label">图片</label>
  <div class="layui-input-inline">
    <input type="text" name="pic" id="pic" required  lay-verify="required" value="{$slide->pic}" placeholder="请上传图片"  class="layui-input">
  </div>
  <button type="button" class="layui-btn upload" data-des="pic"> <i class="layui-icon">&#xe67c;</i>上传图片 </button>
  <div id="pic_box" class="pic">{if([$slide->pic])}
    <dl>
      <dt><img src="{SITE_DIR}{$slide->pic}" data-url="{$slide->pic}"></dt>
      <dd>删除</dd>
    </dl>
    {/if}</div>
</div>

在这段代码下面加入下面代码

<div class="layui-form-item">
  <label class="layui-form-label">图片2</label>
  <div class="layui-input-inline">
    <input type="text" name="picc" id="picc" required  lay-verify="required" value="{$slide->picc}" placeholder="请上传图片"  class="layui-input">
  </div>
  <button type="button" class="layui-btn upload" data-des="picc"> <i class="layui-icon">&#xe67c;</i>上传图片 </button>
  <div id="pic_box" class="pic">{if([$slide->picc])}
    <dl>
      <dt><img src="{SITE_DIR}{$slide->picc}" data-url="{$slide->picc}"></dt>
      <dd>删除</dd>
    </dl>
    {/if}</div>
</div>

前端调用代码

{pboot:slide gid=* num=*}
<img src="[slide:src]">//原本的图片调用
<img src="[slide:picc]">//新增的图片调用
{/pboot:slide}
