    1.php下foreach()错误提示Warning: Invalid argument supplied for foreach()

    错误提示:Warning: Invalid argument supplied for foreach() in E:wampwwwmyshopcart.php on line 95

    二、解决方案:

    错误提示 Warning:Invalid argument supplied for foreach() 的中文意思是说foreach需要是一个数组而给它的是一个无效的参数.

    就是在循环前面加上判断,直接使用is_array判断给的值是不是为数组,代码如下:

    复制代码 代码如下:

    if(is_array($items) && !emptyempty($items)){ 
    foreach( ) 
    }


    或者强制转换数据类型,代码如下:

    复制代码 代码如下:

    foreach((array)$v as $k1 => $v1) { 
         $edu[$k1][$k] = my_h($v1);// v1是最终要入库的数据,进行转义处理 
    }

    2.后台添加导航的错误

    3.首页显示分类产品列表

    在lib_goods.php里加个这个

    /**
     *
    首页获取指定分类产品
     *
     *
    @access      public
     *
    @param       string
     *
    @param       array
     *
    @return      array
     */
    function get_cat_id_goods_list($cat_id = '', $num = '') {
        $sql = 'Select g.goods_id, g.cat_id,c.parent_id, g.goods_name, g.goods_name_style, g.market_price, g.shop_price AS org_price, g.promote_price, ' .
            "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, " .
            "promote_start_date, promote_end_date, g.goods_brief, g.goods_thumb, goods_img, " .
            "g.is_best, g.is_new, g.is_hot, g.is_promote " .
            'FROM ' . $GLOBALS ['ecs']->table ( 'goods' ) . ' AS g ' .
            'LEFT JOIN ' . $GLOBALS ['ecs']->table ( 'category' ) . ' AS c ON c.cat_id = g.cat_id ' .
            "LEFT JOIN " . $GLOBALS ['ecs']->table ( 'member_price' ) . " AS mp " .
            "ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' " .
            "Where g.is_on_sale = 1 AND g.is_alone_sale = 1 AND g.is_delete = 0 " .
            $sql .= " AND (c.parent_id =" . $cat_id . " OR g.cat_id = " . $cat_id . " OR g.cat_id " . db_create_in ( array_unique ( array_merge ( array (
                    $cat_id
                ), array_keys ( cat_list ( $cat_id, 0, false ) ) ) ) ) . ")";
        $sql .= " LIMIT $num";
        $res = $GLOBALS ['db']->getAll ( $sql );
        $goods = array ();
        foreach ( $res as $idx => $row ) {
            $goods [$idx] ['id'] = $row ['article_id'];
            $goods [$idx] ['id'] = $row ['goods_id'];
            $goods [$idx] ['name'] = $row ['goods_name'];
            $goods [$idx] ['brief'] = $row ['goods_brief'];
            $goods [$idx] ['brand_name'] = $row ['brand_name'];
            $goods [$idx] ['goods_style_name'] = add_style ( $row ['goods_name'], $row ['goods_name_style'] );
            $goods [$idx] ['short_name'] = $GLOBALS ['_CFG'] ['goods_name_length'] > 0 ? sub_str ( $row ['goods_name'], $GLOBALS ['_CFG'] ['goods_name_length'] ) : $row ['goods_name'];
            $goods [$idx] ['short_style_name'] = add_style ( $goods [$idx] ['short_name'], $row ['goods_name_style'] );
            $goods [$idx] ['market_price'] = price_format ( $row ['market_price'] );
            $goods [$idx] ['shop_price'] = price_format ( $row ['shop_price'] );
            $goods [$idx] ['thumb'] = empty ( $row ['goods_thumb'] ) ? $GLOBALS ['_CFG'] ['no_picture'] : $row ['goods_thumb'];
            $goods [$idx] ['goods_img'] = empty ( $row ['goods_img'] ) ? $GLOBALS ['_CFG'] ['no_picture'] : $row ['goods_img'];
            $goods [$idx] ['url'] = build_uri ( 'goods', array (
                'gid' => $row ['goods_id']
            ), $row ['goods_name'] );
        }
        return $goods;
    }

    然后是index.php输出

    $smarty->assign('cat_id_goods_list_19', get_cat_id_goods_list(19,10));//进口水果额

    最后前台一遍历

    4.首页显示文章上传的file_url字段 来当图片用

    在对应的php方法里加个 file_url字段即可

    5.后台添加导航碰到这个错误  咋整

    解决下:上面代码可以输出值,但是报错Warning: Illegal string offset 'cat_name' in  ,原因是$catlist数组里面有空数组,空数组里没有cat_name这个字段。最终解决办法是在 foreach 下面加个判断 if(is_array($val)),这样就搞定了。

    6.登陆的时候 登陆没通过 有错误

    构造函数放到方法上面就好了

    7.Ecshop 如何在全站都调用购物车信息 比如买了几件 一共多少钱

    http://www.cnblogs.com/wangblognet/archive/2013/01/23/2873333.html

    8.文章列表页如何显示网页描述字段

    http://www.68ecshop.com/article-933.html

    9.登陆注册页面显示产品分类列表

    根目录的user.php 里大概79行 加一句这个

    $smarty->assign('categories',     get_categories_tree());        // 分类树

    10. Strict Standards: mktime(): You should be using the time() function instead in E:webshopexadminshop_config.php on line 32

    这个错误提示的意思:mktime()方法不带参数被调用时,会被抛出一个报错提示。

    找到文件第32行:

    $auth = mktime();

    将mktime()替换成time()方法,代码为:

    $auth = time();

    11. Strict standards: Redefining already defined constructor for class cls_sql_dump in

    调换一下两个函数的前后位置即可。
    以 includes/modules/payment/alipay.php  为例:
    将下面这两个函数的位置互换一下就OK了,__c**truct()在前,alipay()在后

    1. function alipay()    {
    2. }
    3.  
    4.     function __c**truct()
    5.     {
    6.         $this->alipay();
    7.     }

    12. Strict standards: Non-static method cls_sql_dump::get_random_name() should not be called statically

    13.上传的图片不清楚怎么办

    http://www.51php.com/ecshop/13916.html

    按照路径直接找到根目录下thems/default/goods.dwt这个文件 直接修改模板文件即可

    找到:

    <div class=”good_img”>

    <a href=”javascript:;” onclick=”window.open(‘gallery.php?id={$goods.goods_id}’); return false;” >

    <img src=”{$goods.goods_img}” alt=”{$goods.goods_name|escape:html}” id=”goodsimg” style=”340px;” />

    </a>

    </div>

    修改为:

    <div class=”good_img”>

    <a href=”javascript:;” onclick=”window.open(‘gallery.php?id={$goods.goods_id}’); return false;” >

    <img src=”{$goods.original_img}” alt=”{$goods.goods_name|escape:html}” id=”goodsimg” style=”340px;” />

    </a>

    </div>
