Need help with "if"

Hello guys,

Maybe someone can help me.

I'm using tradeexpert script in my wordpress blog.
To use skimming traffic, I changed the following code in my homepage

From:

<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>">

PHP:

To:

<a href="/webmasters/out.php?s=100,75,65&u=<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>">

PHP:

Now I have installed this plugin:
https://wordpress.org/plugins/page-links-to/

Screenshot of the plugin:


My idea is to use always this code in my posts:

<a href="/webmasters/out.php?s=100,75,65&u=<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>">

PHP:

But when I use a custom URL I want to use the default code:

<a href="<?php the_permalink() ?>" rel="bookmark" title="<?php the_title_attribute(); ?>">

PHP:

Would be great if someone can help me with this

Plugin code:

Thank you guys and a good week to all!

 

Well, you'll need some way to "pick up" that you're using either a modified URL, or the standard permalink. Then you would need to make something akin to:

$link = (something to distinguish which one to use, either custom or permalink) ? the_permalink() : custom_url;

Code (markup):

And then you would just use that $link-variable in the a-tag in the code you have.

Since I dunno how the other plugin works, or what kind of interface it uses, that's about as distinctive that I can get.

 

Hello PoPSiCLe,

Thank you for trying to help me.
Unfortunately I don't have enough skills to complete your code.

Can this file of the plugin help you complete the code?

Thanks!!

 

I'm close to the solution using this code:

add_filter('the_permalink', function( $url ){
    if ( get_post_meta( get_the_ID(), '_links_to', true ) === true) {
        return $url;
    } else {
        return '/webmasters/out.php?s=100,75,65&u=' . $url;
    }
});

PHP:

But unfortunately all my links are appearing with /webmasters/out.php...

Probably the issue is in this code line:

if ( get_post_meta( get_the_ID(), '_links_to', true ) === true) {

PHP:

Plugin code:

Any suggestions?

EDIT
---------------------------------

Fixed!

Just replaced:

if ( get_post_meta( get_the_ID(), '_links_to', true ) === true) {

PHP:

With:

$id=get_the_ID();
    if ( get_post_meta( $id, '_links_to', true )) {

PHP:

Thank you anyway

 

Glad you figured it out! Good work
