织梦dedecms循环判断是否为第一个

判断是否为第一个
dedecms的arclist循环中,判断如果是第一个li,则添加固定的css,否则不加。

{dede:arclist row=4  flag='p'}
 <li [field:global name=autoindex runphp="yes"](@me==1)? @me="class=on":@me="";[/field:global]>[field:global.autoindex/]</li>
{/dede:arclist}

在手机网站详情页模板内,将调用上一页、下一页标签插入。

<ul class="am-pagination blog-pagination">

      <li>{dede:prenext get='mobile_next'/}</li>

Cannot use object of type PHPExcel_RichText as array

不能将富文本对象转换为数组。一般我们在上传导Excel的时候会出现此问题,问题的原因是Excel表格中有富文本对象。

解决方法1:
$student['actual_residence']=(string)$objPHPExcel->getActiveSheet()->getCell("M".$i)->getValue();
原理:将富文本对象转换为string类型。

解决方法2:
其实在PHPExcel中已经有转换的方法写好了,直接调用即可。
$objPHPExcel->getActiveSheet()->getCell("M".$i)->getValue()->__toString();

当然,最简单的方式那就直接把excel表格格式化样式即可。

wamp升级php5.5.12到5.6.30

最近计划入坑Laravel,无奈php>5.6,现用wamp为5.5.12,升级。

1.下载php5.6.30 VC11 x64 Thread Safe,http://windows.php.net/download/
2.wamp/bin/php目录创建php5.6.30目录并复制文件
3.复制php5.5.12下的php.ini、phpForApache.ini、wampserver.conf至php5.6.30目录 下,并将php.ini、phpForApache.ini中的5.5.12全部替换成5.6.30
注:也可复制php.ini-development文件,修改后保存为php.ini及phpForApache.ini
4.删除wamp\bin\apache\apache2.4.9\bin下的php.ini文件
5.wamp中重启服务,此时php版本只显示5.5.12,点击重启,便可出现5.6.30版本,选择。
备注:php5.6以上版本,curl拓展开启问题
php.ini中 ;extension=php_curl.dll 前的;已经去除,但仍提示curl未开启
解决办法:将php安装目录下的libssh2.dll复制到apache的bin目录,并重新启动apache

浏览器同源策略以及跨域手段

同源策略(Same origin policy)

同源策略,它是由Netscape提出的一个著名的安全策略。现在所有支持JavaScript 的浏览器都会使用这个策略。所谓同源是指,域名,协议,端口相同。

那问题来了,如何合法规避浏览器的同源策略呢

跨域资源共享(CORS)

服务器端添加 Header 头信息,指定允许访问的源

以 PHP 语言为例

header("Access-Control-Allow-Origin: http://www.codefun.cn");
header("Access-Control-Allow-Credentials: true");
例如,上面的字段值将允许来自 http://www.codefun.cn 的请求
