在文章中插入广告
其实就是判断查找文章的第一个p,然后,插入代码,放到functions里使用即可。
function themeInit($archive) {
// 判断是否是文章,如果是就插入广告
$ad_code = '<div>这是你的广告</div>';
if ($archive->is('single')) {
$archive->content = prefix_insert_after_paragraph( $ad_code, 2, $archive->content );;
}
}
// 插入广告所需的功能代码
function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
$closing_p = '</p>';
$paragraphs = explode( $closing_p, $content );
foreach ($paragraphs as $index => $paragraph) {
if ( trim( $paragraph ) ) {
$paragraphs[$index] .= $closing_p;
}
if ( $paragraph_id == $index + 1 ) {
$paragraphs[$index] .= $insertion;
}
}
return implode( '', $paragraphs );
}
Typecho Nginx 伪静态规则
适用于nginx使用。军哥lnmp内置:
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php$1 last;
}
apache规则:
RewriteEngine On
RewriteBase /
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^(.*)?$ https://%{SERVER_NAME}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php/$1 [L]
