完整可以的WordPress文章遠程(外鏈)圖片自動保存本地化(親測可用哦)
[重要通告]如您遇疑難雜癥,本站支持知識付費業(yè)務(wù),掃右邊二維碼加博主微信,可節(jié)省您寶貴時間哦!
有些時候我們在寫文章的時候,難免可能要用到別人的圖片,或者說轉(zhuǎn)載文章,就要用到了復(fù)制文章,但是里面的老是別人的,總歸不好,有一天別人站打不開,在想查看文章的時候,圖片就全是XXX的,感覺會很不爽,如何才能讓讓WordPress遠程文章中圖片本地化呢?方法固然有,插件不少,還是秉著少用一個插件略微安全的原則,還是使用代碼比較好,具體呢請看;
百度了一下,網(wǎng)上都是很多的ctrl+c然后加V,復(fù)制粘貼類型,也都不測試,根本就是不能用的代碼;比如(網(wǎng)上都是這個109行代碼的保存):
//自動本地化外鏈圖片 add_filter('content_save_pre', 'auto_save_image'); function auto_save_image($content) { $upload_path = ''; $upload_url_path = get_bloginfo('url'); //上傳目錄 if (($var = get_option('upload_path')) !=''){ $upload_path = $var; } else { $upload_path = 'wp-content/uploads'; } if(get_option('uploads_use_yearmonth_folders')) { $upload_path .= '/'.date("Y",time()).'/'.date("m",time()); } //文件地址 if(($var = get_option('upload_url_path')) != '') { $upload_url_path = $var; } else { $upload_url_path = bloginfo('url'); } if(get_option('uploads_use_yearmonth_folders')) { $upload_url_path .= '/'.date("Y",time()).'/'.date("m",time()); } require_once ("../wp-includes/class-snoopy.php"); $snoopy_Auto_Save_Image = new Snoopy; $img = array(); //以文章的標(biāo)題作為圖片的標(biāo)題 if ( !emptyempty( $_REQUEST['post_title'] ) ) $post_title = wp_specialchars( stripslashes( $_REQUEST['post_title'] )); $text = stripslashes($content); if (get_magic_quotes_gpc()) $text = stripslashes($text); preg_match_all("/ src=(\"|\'){0,}(http:\/\/(.+?))(\"|\'|\s)/is",$text,$img); $img = array_unique(dhtmlspecialchars($img[2])); foreach ($img as $key => $value){ set_time_limit(180); //每個圖片最長允許下載時間,秒 if(str_replace(get_bloginfo('url'),"",$value)==$value&&str_replace(get_bloginfo('home'),"",$value)==$value){ //判斷是否是本地圖片,如果不是,則保存到服務(wù)器 $fileext = substr(strrchr($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;//圖片保存的路徑目錄 !is_dir("..".$filepath) ? mkdirs("..".$filepath) : null; //$filename = date("His",$filetime).random(3); $filename = substr($value,strrpos($value,'/'),strrpos($value,'.')-strrpos($value,'/')); //$e = '../'.$filepath.$filename.'.'.$fileext; //if(!is_file($e)) { // copy(htmlspecialchars_decode($value),$e); //} $fp = @fopen("..".$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; //添加數(shù)據(jù)庫記錄 $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); //替換文章里面的圖片地址 } } } $content = AddSlashes($text); remove_filter('content_save_pre', 'auto_save_image'); return $content; } function mkdirs($dir) { if(!is_dir($dir)) { mkdirs(dirname($dir)); mkdir($dir); } return ; } function dhtmlspecialchars($string) { if(is_array($string)) { foreach($string as $key => $val) { $string[$key] = dhtmlspecialchars($val); } }else{ $string = str_replace('&', '&', $string); $string = str_replace('"', '"', $string); $string = str_replace('<', '<', $string); $string = str_replace('>', '>', $string); $string = preg_replace('/&(#\d;)/', '&\1', $string); } return $string; }
我也是用了此代碼,然后看我使用的效果;遠程圖片可以正常下載在,但是在顯示文章會出現(xiàn)路徑不正確;是不是,這就很尷尬了,那就自己動手豐衣足食,那我們就來操作一下吧;
修改后的代碼(非常滴可用):
//自動本地化外鏈圖片 add_filter('content_save_pre', 'auto_save_image'); function auto_save_image($content) { $upload_path = ''; $upload_url_path = get_bloginfo('url'); //上傳目錄 if (($var = get_option('upload_path')) != '') { $upload_path = $var; } else { $upload_path = 'wp-content/uploads'; } if (get_option('uploads_use_yearmonth_folders')) { $upload_path.= '/' . date("Y", time()) . '/' . date("m", time()); } //文件地址 if (($var = get_option('upload_url_path')) != '') { $upload_url_path = $var; } else { $upload_url_path = get_bloginfo('url'); } if (get_option('uploads_use_yearmonth_folders')) { $upload_url_path.= '/wp-content/uploads/' . date("Y", time()) . '/' . date("m", time()); } require_once ("../wp-includes/class-snoopy.php"); $snoopy_Auto_Save_Image = new Snoopy; $img = array(); //以文章的標(biāo)題作為圖片的標(biāo)題 if (!empty($_REQUEST['post_title'])) $post_title = wp_specialchars(stripslashes($_REQUEST['post_title'])); $text = stripslashes($content); if (get_magic_quotes_gpc()) $text = stripslashes($text); 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); //每個圖片最長允許下載時間,秒 if (str_replace(get_bloginfo('url'), "", $value) == $value && str_replace(get_bloginfo('home'), "", $value) == $value) { //判斷是否是本地圖片,如果不是,則保存到服務(wù)器 $fileext = substr(strrchr($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; //圖片保存的路徑目錄 !is_dir(".." . $filepath) ? mkdirs(".." . $filepath) : null; //$filename = date("His",$filetime).random(3); $filename = substr($value, strrpos($value, '/'), strrpos($value, '.') - strrpos($value, '/')); //$e = '../'.$filepath.$filename.'.'.$fileext; //if(!is_file($e)) { // copy(htmlspecialchars_decode($value),$e); //} $fp = @fopen(".." . $filepath . $filename .

PS:值得說明的一下,在老梁博客網(wǎng)站上復(fù)制的代碼可能會轉(zhuǎn)碼成GBK,請使用的時候轉(zhuǎn)換成U8再使用哦,切記哦,不然會導(dǎo)致網(wǎng)站掛掉的哦~~~具體請看下面的鏈接即可;
