今天粘贴代码时候发现半角的" " 都变成了乱七八糟的有半角有全角“”,代码粘下来用的时候就困难比较多了，总结一下解决方法：
1、插件方法
Quotmarks Replacer是一个通过禁用wptexturize函数来解决WordPress自动将半角的单引号、双引号和省略号转换为全角标点的问题。使后台输入的标点格式与前台读者浏览的标点格式保持一致的插件。

2、直接更改WP安装目录下wp-includes/formatting.php更改里面的过滤参数就可以避免这种情况了。具体如下：
#文件：wp-includes/formatting.php，将以下代码

$static_characters = array_merge(array('---', ' -- ', '--', 'xn–', '...', '``', '\'s', '\'\'', ' (tm)'), $cockney);
$static_replacements = array_merge(array('—', ' — ', '–', 'xn--', '…', '“', '’s', '”', ' ™'), $cockneyreplace);
$dynamic_characters = array('/\'(\d\d(?:’|\')?s)/', '/(\s|\A|")\'/', '/(\d+)"/', '/(\d+)\'/', '/(\S)\'([^\'\s])/', '/(\s|\A)"(?!\s)/', '/"(\s|\S|\Z)/', '/\'([\s.]|\Z)/', '/(\d+)x(\d+)/');
$dynamic_replacements = array('’$1','$1‘', '$1″', '$1′', '$1’$2', '$1“$2', '”$1', '’$1', '$1×$2');

替换成

$static_characters = array_merge(array(), $cockney);
$static_replacements = array_merge(array(), $cockneyreplace);
$dynamic_characters = array('/(\d+)x(\d+)/');
$dynamic_replacements = array('$1×$2');

3、编辑 wp-includes/formatting.php
将如下代码

for ( $i = 0; $i < $stop; $i++ ) {
         $curl = $textarr[$i];

        if (isset($curl{0}) && '<' != $curl{0} && '[' != $curl{0} && $next && !$has_pre_parent) { // If it's not a tag
            // static strings
            $curl = str_replace($static_characters, $static_replacements, $curl);
            // regular expressions
            $curl = preg_replace($dynamic_characters, $dynamic_replacements, $curl);
        } elseif (strpos($curl, '<code') !== false || strpos($curl, '<kbd') !== false || strpos($curl, '<style') !== false || strpos($curl, '<script') !== false) {
            $next = false;
        } elseif (strpos($curl, '<pre') !== false) {
            $has_pre_parent = true;
        } elseif (strpos($curl, '</pre>') !== false) {
            $has_pre_parent = false;
        } else {
            $next = true;
        }

        $curl = preg_replace('/&([^#])(?![a-zA-Z1-4]{1,8};)/', '&#038;$1', $curl);
        $output .= $curl;
    }

改为

for ( $i = 0; $i < $stop; $i++ ) {
         $curl = $textarr[$i];

        if (isset($curl{0}) && '<' != $curl{0} && '[' != $curl{0} && $next && !$has_pre_parent) { // If it's not a tag
            // static strings
            //$curl = str_replace($static_characters, $static_replacements, $curl);
            // regular expressions
            //$curl = preg_replace($dynamic_characters, $dynamic_replacements, $curl);
        } elseif (strpos($curl, '<code') !== false || strpos($curl, '<kbd') !== false || strpos($curl, '<style') !== false || strpos($curl, '<script') !== false) {
            $next = false;
        } elseif (strpos($curl, '<pre') !== false) {
            $has_pre_parent = true;
        } elseif (strpos($curl, '</pre>') !== false) {
            $has_pre_parent = false;
        } else {
            $next = true;
        }

        $curl = preg_replace('/&([^#])(?![a-zA-Z1-4]{1,8};)/', '&#038;$1', $curl);
        $output .= $curl;
    }

方法2和3其实使之一样，修改过滤方法的具体内容而已，只是地方不一样，3是直接注销掉过滤方法的调用了。希望不会出什么别的问题。
