RT.

ThinkPHP的conf文件中的Convention.php有一个配置选项

'DEFAULT_FILTER'        =>  'htmlspecialchars', // 默认参数过滤方法 用于I函数...
Copy after login
默认这个方法是开启的。也就是说,我们往数据库里面存储的数据中都会经过htmlspecialchars这个函数的转义处理。

我在我的项目中使用了Kindeditor富文本编辑器(或许你使用的是Ueditor\ckeditor),通过富文本编辑器编辑文章的内容然后存储到数据库中,再从数据库中读取显示到网页上来。

在这个过程中,我遇到一个问题,当我在insert方法直接显示我将提交到数据库里的文本数据时,能够正常解析成HTML页面,但是当我再从数据库里面读取HTML数据时,文章内容就变成了一整段HTML代码。dump输出我读取到的数组内容,可以很清楚的看到是已经转义的内容。

1.数据库中存储的内容以及读取出来的文章内容实例:

<p>
	你们知道吗?
</p>
Copy after login
2.在html页面中解析出来的内容效果:
&ldquo;
        <p>
	<span style="white-space:pre">	</span><img src="/static/imghw/default1.png"  data-src="/17joys/Public/kindeditor/attached/image/20140807/20140807110915_31727.jpg"  class="lazy" alt=""    style="max-width:90%"  style="max-width:90%">
<span style="white-space:pre">	</span></p>
&rdquo;

很明显可以看出,原来应该变成HTML标签的内容现在被解析成了文本里面的内容,而且在文本内容的最外面还加上了双引号。
Copy after login

正常的显示应该是没有双引号的才对。数据库读取出来的数据就是HTML页面的源代码,然后插入HTML页面之后,标签被解释,标签内的内容显示成页面。

通过上面的分析,可以确定,是ThinkPHP在内容存储的过程中自动对内容进行了转义处理,导致了数据库中存储的内容变成了转义后的内容,再次读出来的时候HTML会自动将原本属于标签的内容转义成为正文文本。

所以,果断到TP的conf目录下找convention.php配置文件,将DEFAULT_FILTER功能禁用掉,以后需要使用的时候再手动调用即可。

再次测试,这一次就解决了问题了。
