How to append a URL parameter to all outbound URLs
Inbound vs Outbound links: I guess it’ll be helpful to clarify these concepts: Inbound links = links from another website to your own website. Outbound links = links from your website to another website. An external link would be any link that points to any domain other than the domain the link exists on. From … Read more
How to auto-approve internal pingbacks?
The comment handling is somewhat difficult to follow in code. My educated guess is that you have comment whitelist enabled (Comment author must have previously approved comment), but since pingbacks are not identifiable by author they are treated as requiring moderation.
How can I find all internal links that are pointing to post/page?
I would search the database’s wp_posts table to find the URL(s) you are looking for, using phpmyadmin.
Add / Remove Post Type from “Link to existing content” popup
Old question but I found an answer at Here by Simon Hampel at the bottom. Cool filter, but I coulnd’t find a whole lot of documentation on it so I’m not 100% sure everything it’s connected to. One thing I do know is it’s used to pull the links on ‘Link to existing content’. Put … Read more
opening links in new tab using – add_filter( ‘the_content’, ‘make_clickable’);
I am not sure if there’s a native function for this, but a little regex might help the case: function open_links_in_new_tab($content){ $pattern = ‘/<a(.*?)?href=[\'”]?[\'”]?(.*?)?>/i’; $content = preg_replace_callback($pattern, function($m){ $tpl = array_shift($m); $hrf = isset($m[1]) ? $m[1] : null; if ( preg_match(‘/target=[\'”]?(.*?)[\'”]?/i’, $tpl) ) { return $tpl; } if ( trim($hrf) && 0 === strpos($hrf, ‘#’) … Read more
Is it possible to link to draft pages?
I should start off by saying that linking to drafts will only work for logged in users (with appropriate permissions) – other users will simply hit a 404 Not Found! You’d be much better off getting all your content ready & published, or only link to it once it is ready! Nevertheless, to answer your … Read more
Links redirecting to localhost after migration to server
if anyone comes across with this issue, I resolved it by editing both the ‘home’ and ‘siteURL’ fields in the wp-options table of the database on the server (not the localhost one) to replace the ‘localhost/wordpress’ with ‘http://www.youehostedsitename‘. replace Both ‘home’ and ‘siteurl’.
Default Image Link Removal
This is not able to be changed through a filter. In WordPress 2.9.2 and lower, the setting can be changed in /wp-admin/options.php. The image_default_link_type field is set to “file” by default. If you set it to “none”, then scroll to the bottom and save, it will disable media links. This option has been removed from … Read more
How can I link to the most recent post in a category?
It’s not built into core, but it’s certainly possible to add, however – I wouldn’t consider it a good idea to have a single post available at multiple URLs, so a redirect is probably best. Of course, it will require a bit of PHP, as WordPress doesn’t operate on magic or willpower. First, we hook … Read more
