Solved: issue with wordpressMU image or media uploading

Single wordpress and wordpressMu has different behaviour.. If you are using apache webserver then there is no issue but if you are using than there is issue with image mapping. specially with nginx web server.
You need to write the rewrite rule for image. Also you need to check about folder permission in your “blogs.dir” directory. change folder permission to 777.
For single wordpress there is uploads folder is present but for wordpressMu there is no uploads folder present in directory. You should look for blogs.dir folder which is present in wordpressMu/wp-content folder.

For solve the issue add the following lines in your apache configuration(httpd.conf) file. If this file is not present then add following lines in your .htaccess file.

RewriteEngine On
RewriteBase /

#uploaded files
RewriteRule ^(.*/)?files/$ index.php [L]
RewriteCond %{REQUEST_URI} !.*wp-content/plugins.*
RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteCond %{REQUEST_URI} ^.*/wp-admin$
RewriteRule ^(.+)$ $1/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule . - [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(wp-.*) $2 [L]
RewriteRule  ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

One another issue.
You should check the “Upload File Types” settings going here.
http://yoursite/wp-admin/wpmu-options.php

Check the “Max upload file size” and also check the “Blog upload space”

For Nginx you will find the configuration code from https://purabtech.in/image-upload-issue-in-wordpressmu-with-nginx/

If you have still facing issue with image uploading in wordpressMU. Feel free to write to me or write a comment.

How to exclude images from wordpress post

In one of our project, we got the requirement of exclude images from wordpress post while showing post. We have written code for excluding the image from Post.

How to exclude images from wordpress post

you can use following code in functions.php file or you can use in single.php file. These files you can find in wordpress theme folder.

For changing the code you can use the wordpress admin -> editor section.

Above line I added in showing post without image.


<?php
$FormatedContent = content_with_formatting();
$content = the_content();
$postWithoutImage = preg_replace('/<img[^>]+./’,'' $FormatedContent);
echo $postWithoutImage;
?>

In above code we are checking the image tag and replacing with none.

If you want to find all images from post then Use following command.

preg_match_all('/<img[^>]+>/i',YOUR_text, $result);

You need to add following function in your function.php file(Theme files).

function content_with_formatting($more_link_text = ‘(more…)’, $stripteaser = 0, $more_file = ”)
{
$content = get_the_content($more_link_text, $stripteaser, $more_file);
$content = apply_filters(‘the_content’, $content);
$content = str_replace(‘]]>’, ‘]]>’, $content);
return $content;
}

If you want to Hide all images using CSS then use following code

img{
display:none;
}

Just put above code in your style.css file.
