我的wordpress网站上的搜索结果是404。当我点击搜索按钮时，它试图在不存在wordpress/wordpress/index的路径中打开一个php文件。php。我不知道这是如何配置的，也不知道在哪里重置搜索按钮操作代码。

我认为安装“搜索一切插件”可以解决我的搜索问题，它做到了。这项测试做得很好。但我需要找出如何解决搜索按钮的问题。

我刚开始使用wordpress，不懂php。

编辑：我刚刚为我的主页做了一个“查看源”并找到

<form id="searchform" class="searchform" method="get" action="http://localhost/wordpress/wordpress/index.php">

我还做了一个

sudo grep -r "searchForm" .

找到我所有痛苦的根源，

./wp-content/themes/graphene/searchform.php:<form id="searchform" class="searchform" method="get" action="<?php echo get_home_url(), $_SERVER[\'PHP_SELF\']; ?>">

似乎url是从PHP-SELF获取其值的

所以我搜索PHP-SELF的价值来源

sudo grep --exclude-dir=.svn -r "SERVER\\[\'PHP_SELF\'\\] = " .
./wp-includes/load.php:     $_SERVER[\'PHP_SELF\'] = $PHP_SELF = preg_replace( \'/(\\?.*)?$/\', \'\', $_SERVER["REQUEST_URI"] );
./wp-login.php:     $_SERVER[\'PHP_SELF\'] = str_replace( $_SERVER[\'PATH_INFO\'], \'\', $_SERVER[\'PHP_SELF\'] );

现在，似乎使用REQUEST\\u URI初始化PHP\\u SELFORIts PATH\\u INFO和PHP\\u SELF

随着我进一步挖掘，它变得越来越复杂。我的问题是，What is expected to be the value of PHP_SELF.

sudo grep --exclude-dir=.svn -r "SERVER\\[\'REQUEST_URI\'\\] = " .
