这两天在和老廖在弄wordpress发布磁力链的时候发现，如果链接地址是磁力链，发布上去会被替换。怎么测试都不行，把post接口发给公司的程序猿，他把里面所有涉及过滤的参数都注释掉了，不影响发布，但是还是被替换掉。然后没有办法，去百度搜了一下，没找到解决办法，但是找到了另外一个发布接口，抱着试一试的心态下载试了试，发现还是被替换掉。
于是开始研究发布接口文件，结果看到了接口的作者信息是个淘宝店的网址，点击进去，刚好店主也在，于是就咨询了一下，结果他说可以解决，收费十元。急着用，也就直接拍下了，反正也不够买盒烟的，店主有意思，说今天没开张，开张了都不收钱了。
分享他的解决方案
在wp-includes目录内找到post.php，搜索以下内容：
$postarr = sanitize_post($postarr, 'db');
注释掉，就可以了。
十块钱，买了三句话，果然熟悉wordpress的，知识就是金钱，古人诚不欺我。 阅读全文…
lnmp环境下的VPS主机，在安装了wordpress博客程序之后，上传了新的模板主题之后，发现后台不显示，或者以前的模板无法编辑，不管你安装什么主题都只显示启用的这个，如果是上传安装同一个提示安装的目录有存在，搞得人相当郁闷。
主要问题如下：1.WordPress后台主题只能显示启用的这一个。2.外观编辑无法使用。3.页面里面的模板功能无法使用
结果在群友“孤独依人”和“安豫”的指导下发现解决办法:原来是lnmp的php.ini禁止了scandir函数，导致模板无法被缓存，于是就找不到新模板了。
翻看php手册，scandir() 函数是这样被定义的：“scandir() 函数返回一个数组，其中包含指定路径中的文件和目录”，wordpress可能居于这个函数去开发的，所以就只显示了一个主题。
具体操作步骤：
在以下路径找到php配置文件： /usr/local/php/etc/php.ini
下载后打开编辑：搜索 “scandir” 然后将这个删除掉,顺便把”逗号”也删除了,然后保存退出
最后重启LNMP: /root/lnmp restart
这样就可以显示了。
今天在调试前几天共享的程序时候，看到一个提示：
Warning: fsockopen() has been disabled for security reasons in /wwwroot/FTP1EE7B/htdocs/inc/Taoapi_Util.php on line 807
PHP程序开头加上：
@error_reporting (E_ALL & ~E_NOTICE & ~E_WARNING);
