WORDPRESS远程图片本地化实现程序

wordpress博客发文章时如果带有图片不会自动下载而是使用原网站图片了,下面我们一起看看WORDPRESS远程图片本地化例子.

将远程图片本地化代码写入/wp-content/themes/twentyfourteen/主题的functions.php文件中即可,以后每次在wordpress发布文章时如果文章中含有外链图片就会自动本地化了,无需任何设置操作非常方便,代码如下:

// 远程图片本地化

add_filter(‘content_save_pre’, ‘auto_save_image’);

function auto_save_image($content){

$upload_dir = wp_upload_dir(date(‘Y/m’));

$upload_path = $upload_dir['path'];

$upload_url_path = $upload_dir['url'];

require_once (“../wp-includes/class-snoopy.php”);

$snoopy_Auto_Save_Image = new Snoopy;

$img = array();

if (!emptyempty($_REQUEST['post_title']))

$post_title = wp_specialchars(stripslashes($_REQUEST['post_title']));

$text = stripslashes($content);

preg_match_all(“/ src=(＼”|＼’){0,}(http:＼/＼/(.+?))(＼”|＼’|＼s)/is”, $text, $img);

$img = array_unique(dhtmlspecialchars($img[2]));

foreach ($img as $key => $value){

set_time_limit(180); //每个图片最长允许下载时间,秒

if(str_replace(get_bloginfo(‘url’), “”, $value) == $value && str_replace(get_bloginfo(‘home’), “”, $value) == $value){

$fileext = substr(strrchr($value, ‘.’), 1);

$fileext = strtolower($fileext);

if($fileext == “” || strlen($fileext) > 4)

$fileext = “jpg”;

$savefiletype = array(‘jpg’, ‘gif’, ‘png’, ‘bmp’);

if (in_array($fileext, $savefiletype)){

if($snoopy_Auto_Save_Image->fetch($value)){

$get_file = $snoopy_Auto_Save_Image->results;

}else{

echo “error fetching file: ” . $snoopy_Auto_Save_Image->error . “<br>”;

echo “error url: ” . $value;

die();

}

$filetime = time();

$filepath = “/” . $upload_path; //图片保存的路径目录

$filename = substr($value, strrpos($value, ‘/’), strrpos($value, ‘.’) – strrpos($value, ‘/’));

$fp = @fopen(“..” . $filepath . $filename . “.” . $fileext, “w”);

@fwrite($fp, $get_file);

fclose($fp);

$wp_filetype = wp_check_filetype($filename . “.” . $fileext, false);

$type = $wp_filetype['type'];

$post_id = (int)$_POST['temp_ID2'];

$title = $post_title;

$url = $upload_url_path . $filename . “.” . $fileext;

$file = $_SERVER['DOCUMENT_ROOT'] . $filepath . $filename . “.” . $fileext;

$attachment = array(‘post_type’ => ‘attachment’,

‘post_mime_type’ => $type,

‘guid’ => $url,

‘post_parent’ => $post_id,

‘post_title’ => $title,

‘post_content’ => ”,

);

$id = wp_insert_attachment($attachment, $file, $post_parent);

$text = str_replace($value, $url, $text); //替换文章里面的图片地址

}

}

}

$content = AddSlashes($text);

remove_filter(‘content_save_pre’, ‘auto_save_image’);

return $content;

}

function dhtmlspecialchars($string){

if(is_array($string)){

foreach($string as $key => $val){

$string[$key] = dhtmlspecialchars($val);

} //开源软件:phpfensi.com

}else{

$string = str_replace(array(‘&’, ‘”‘, ‘<‘, ‘>’), array(‘&’, ‘"’, ‘<’, ‘>’), $string);

if(strpos($string, ‘&#’) !== false) {

$string = preg_replace(‘/&((#(＼d{3,5}|x[a-fA-F0-9]{4}));)/’, ‘&＼＼1′, $string);

}

}

return $string;
