I need to turn this code:
<?php if ( function_exists( 'echo_ald_crp' ) ) echo_ald_crp(); ?>
into a shortcode. Can someone help me do this? I have researched but am just lost to be honest. Thanks!

It's a plugin that displays related blog posts based off of the page title.Brian Schnurr– Brian Schnurr2016-07-28 21:05:34 +00:00Commented Jul 28, 2016 at 21:05

If you're adding this to the end of every single posts content, you would be better off adding it to your theme template instead of as a shortcodeTom J Nowell– Tom J Nowell ♦2016-07-29 10:05:10 +00:00Commented Jul 29, 2016 at 10:05

Init your shortcode
add_shortcode('shortcode_ald_crp', 'myshortcode_echo_ald_crp');
The function what you want:
function myshortcode_echo_ald_crp() {
ob_start();
if ( function_exists( 'echo_ald_crp' ) ) echo_ald_crp();
return ob_get_clean();
}
you call you shortcode in a post like this:
[shortcode_ald_crp]
Or into the php code:
echo do_shortcode('[shortcode_ald_crp]');
UPDATE
Change the function add_shortcode
shortcode_ald_crp for myshortcode_echo_ald_crp

Thanks! I tried adding the shortcode [shortcode_ald_crp] but it just displays that text rather than the blog posts. I added everything you said to the functions. What would cause that? Thanks!Brian Schnurr– Brian Schnurr2016-07-28 21:09:40 +00:00Commented Jul 28, 2016 at 21:09

are you sure
that echo_ald_crp()return the whole blog post? Because it is suppose to alter the "output".Jean-philippe Emond– Jean-philippe Emond2016-07-28 21:13:21 +00:00Commented Jul 28, 2016 at 21:13 -
Yes. I am currently using the PHP script on my product page template, and it's showing the related blog posts.Brian Schnurr– Brian Schnurr2016-07-28 21:16:01 +00:00Commented Jul 28, 2016 at 21:16

I added this to my functions:
//blog posts add_shortcode('shortcode_ald_crp', 'myshortcode_echo_ald_crp'); function shortcode_ald_crp() { ob_start(); if ( function_exists( 'echo_ald_crp' ) ) echo_ald_crp(); return ob_get_clean(); }Brian Schnurr– Brian Schnurr2016-07-28 21:22:11 +00:00Commented Jul 28, 2016 at 21:22 -
So all you see is
[shortcode_ald_crp]? And this code is in functions.php of your active theme?czerspalace– czerspalace2016-07-28 21:32:02 +00:00Commented Jul 28, 2016 at 21:32
Do you mean something like this (untested):
// function for your shortcode
function shortcode_action($atts) {
ob_start();
if ( function_exists( 'echo_ald_crp' ) ) echo_ald_crp();
$content = ob_get_clean();
return $content;
}
// creates shortcode [shortcodehandle] so change it accordingly
add_shortcode( 'shortcodehandle', 'shortcode_action' );
Update: using ob_get_contents to return the content of the output of echo_ald_crp.
Update 2: using ob_get_clean() as highlighted by @jgraup in the comments.

It's probably better to use ob_get_clean() - php.net/manual/en/function.ob-get-clean.php - ob_get_contents doesn't clear the output buffer.jgraup– jgraup2016-07-29 02:45:59 +00:00Commented Jul 29, 2016 at 2:45

@jgraup Great catch, I've updated the answer.2016-07-29 09:27:47 +00:00Commented Jul 29, 2016 at 9:27

While you're at it, maybe wrap it all in the conditional. No need to run excess functions if nothing will yield ;)jgraup– jgraup2016-07-29 13:26:50 +00:00Commented Jul 29, 2016 at 13:26
