Removing everything BUT Images in a WordPress Post

A while back I wrote an article on Removing Images from a WordPress Post. Sebastian asked an interesting question; he wanted to remove everything but the images. This is actually pretty straightforward; here is how you do it:

 
.
.
.

           $beforeEachImage = "";
           $afterEachImage = "
";
           preg_match_all("/(]*>)/",get_the_content(),$matches,PREG_PATTERN_ORDER);
           for( $i=0; isset($matches[1]) && $i < count($matches[1]); $i++ ) {
                 echo $beforeEachImage . $matches[1][$i] . $afterEachImage;
           }
?>
.
.
.

Keep in mind this code needs to be in the WordPress Loop and you can control what is around each image using the variables beforeEachImage and afterEachImage above.

Moving a WordPress Install from one Domain (A) to another Domain (B)

From time to time I had have to move one installation of WordPress from one domain (let’s call it domain A) to a new domain (let’s call it domain B). Because WordPress embeds the domain all over the data schema (not faulting; simply disclosing) you have to make a lot of dB changes for the updated site location to function. Here is the quick and dirty way to move the data:

UPDATE wp_posts SET post_content = REPLACE(post_content,"[OLD_DOMAIN]","[NEW_DOMAIN]");
UPDATE wp_posts SET guid = REPLACE(guid,"[OLD_DOMAIN]","[NEW_DOMAIN]");
UPDATE wp_options SET option_value = REPLACE(option_value,"[OLD_DOMAIN]","[NEW_DOMAIN]");
UPDATE wp_postmeta SET meta_value = REPLACE(meta_value,"[OLD_DOMAIN]","[NEW_DOMAIN]");

Finally, for the final bit of trickery if you are using Advanced Caching on the site there is a great place where the localized PATH is hard coded. Edit your new and updated path on file advanced-cache.php

vi wp-content/advanced-cache.php

Removing Images in a WordPress Post (Revisited)

A while back I wrote a semi-popular post on removing images from a WordPress post — today I am revisiting it. The original solution used the_content() and the output buffer to remove the images out of the post. Now that I have used WordPress a bit longer and candidly had to use the solution again and thought “what was I thinking” I thought I would share the cleaner solution:

 echo preg_replace('/<img[^>]+./','',get_the_content()); ?>

Removing Images from a WordPress Post

Today I ran across a unique need to remove images from a WordPress post in a specific post loop. Because there is no way to do a “read more” excerpt while taking strict control of the raw content from the_content() I was limited to capturing and manipulating the content from PHP’s output buffer. My solution: obtain the output from the_content() and remove the image tags from the post using preg_replace().

Here is the solution:

.
.
.

   ob_start();
   the_content('Read the full post',true);
   $postOutput = preg_replace('/]+./','', ob_get_contents());
   ob_end_clean();
   echo $postOutput;
?>
.
.
.
