5 WordPress Features You Probably Didn't Know About
Hidden deep inside the WordPress engine lies a ton of useful features that many developers don't even know about.. Many do not know about these functions, most likely because WordPress CODEX is underdeveloped and not everything is there, and even more so in Russian and Ukrainian.
Due to the great usefulness of such functions, I decided to post my favorite ones. . Some of them are very simple and can be used when developing your plugins., others may be used less frequently, but all these features are very useful.
wp_mail function ()
wp_mail - super easy feature to send mail. You can even send email with attachments.

1 2 3 4 5 6 7 8 9 10 |
<?php $to = 'user@wp-admin.com.ua'; $subject = 'Blog about WordPress!'; $message = 'Check it out -- my blog is emailing you!' $mail = wp_mail($to, $subject, $message); if($mail) echo 'Your message has been sent!'; else echo 'There was a problem sending your message. Please try again.'; ?> |
You can read more about the wp_mail function in codex wordpress. You can also read there that the function has two additional parameters $headers and $attachments, they make it possible to set up email headers and attach a file.

<?php $attachments = array(WP_CONTENT_DIR . '/uploads/file_to_attach.zip'); $headers = 'From: My Name <myname@wp-admin.com.ua>' . "\r\n"; wp_mail('test@test.com', 'subject', 'message', $headers, $attachments); ?> |
wp_loginout function()
Adds a login link / Exit the page without the need to enter the admin panel. If you have not logged in yet, then at the place where the function was located, there will be an inscription Login, if you enter, then the inscription will change to Exit. Very handy if you don't want to manually type /wp-admin/ or /wp-login.php.
We add the function anywhere in the template like this <? wp_loginout(); ?>.

clean_url functions() is esc_url()
Use esc_url () instead of obsolete clean_url(). The function makes the correct url addresses. For example, ampersand character converts to HTML special character. The function also knows how to add the missing http at the beginning of the url address. In a word, the function fixes poorly structured url addresses.

wpauto function()
The function is used to filter the full and brief content of the page, output by functions the_content and the_excerpt. I think the operation of the function is easy to understand with a simple example taken from wordpress code.
Code in the template:
|
1 2 3 4 5 6 7 8 9 10 |
<?php $some_long_text = <<<TXT Some long text that has many lines and paragraphs in it. TXT; echo wpautop($some_long_text); ?> |
Output code:
|
1 2 3 |
<p>Some long text<br/> that has many lines</p> <p>and paragraphs in it.</p> |
fetch_feed function()
Extracts the external channel and analyzes it. Uses SimplePie and FeedCache functions to retrieve, analysis and automatic caching. Deprecated analogue of the fetch_feed function() this is wp_rss().
