[英]Using preg_replace need to replace random directory in an image src
I have been struggling with this now for 2 hours and it's driving me nuts. 我已经为此苦苦挣扎了2个小时,这真让我发疯。 And I don't think it is likely hard. 而且我认为这可能很难。 I am using Wordpress and need to replace the IMG urls from an old path to a new path. 我正在使用Wordpress,需要将IMG网址从旧路径替换为新路径。 Problem is..everything about the url is static except a particular directory which is random. 问题是..除了特定的随机目录之外,所有关于URL的信息都是静态的。
Example: 例:
https://cdn2.content.mysite.com/uploads/user/76eb326b-62ff-4d37-bf4b-01a428e2f9f6/0ffd6c15-8a13-437c-9661-36edfe11cb41/Image/ b1493cd89a29c0a2d1d8e0939f05d8ee /booth_w640.jpeg
should become 应该成为
/wp-content/uploads/imports/booth_w640.jpeg /wp-content/uploads/imports/booth_w640.jpeg
The bold part is random. 粗体部分是随机的。 So I have this in my wordpress functions.php 所以我在wordpress functions.php中有这个
function replace_content($content) {
$reg = '#/https://cdn2.content.mysite.com/uploads/user/76eb326b-62ff-4d37-bf4b-01a428e2f9f6/0ffd6c15-8a13-437c-9661-36edfe11cb41/Image/([^/]+)#i';
$rep = '/wp-content/uploads/imports';
$content = preg_replace($reg, $rep ,$content);
return $content;
}
add_filter('the_content','replace_content');
but that isn't working. 但这不起作用。 I can't figure it out. 我不知道。 Any help? 有什么帮助吗?
I think what you need is: 我认为您需要的是:
function replace_content($content) {
$reg = '#/static-part-of-url/([^/]+)#i';
$rep = '/wp-content/uploads/imports';
$content = preg_replace($reg, $rep ,$content);
return $content;
}
add_filter('the_content','replace_content');
Using a different delimiter than /
is better when trying to match URLs. 尝试匹配URL时,使用不同于/
分隔符会更好。
I determined the answer to my problem using the below code 我使用以下代码确定了问题的答案
preg_match( '/src="([^"]*)"/i', $content, $match ) ;
$getURL = $match[1];
$urlArr = explode("/",$getURL);
$fileName = end($urlArr);
$newURL = "/blog/wp-content/uploads/imports/" . $fileName;
$content = str_replace($getURL, $newURL, $content);
