[Resolved] Using elements to implement php script

[Karsten]

Hey friends,

could you please tell me the correct procedere to implement this script via Elements. I have tried hooks but always website is blocked afterwards. Thank you

<?php
add_filter( ‘generate_smooth_scroll_elements’, function( $elements ) {
$elements[] = ‘a[href*=”#”]’;

return $elements;
} );

Hi there,

so the GP Hook elements are for inserting code / content inside the themes templates.
And this means you cannot hook in certain codes including add_filter as those are also a Hook ( a filter hook ) that has be to called from your functions.php.

You must use one of the methods provided here instead:

I will continue on this thread and ask if there is any obvious problems adding this code in a GP-hook? Because I can’t make it work. Only with code snippets I can, but there shouldn’t be a problem using a GP-hook with this one?

<?php

function add_content_after_addtocart() {
	
	// get the current post/product ID
	$current_product_id = get_the_ID();
     
  // get the product based on the ID
  $product = wc_get_product( $current_product_id );
     
  // get the "Checkout Page" URL
  $checkout_url = WC()->cart->get_checkout_url();
     
  // run only on simple products
  if( $product->is_type( 'simple' ) ){
      echo '<div class="clear-sec">';
      echo '</div>';
      echo '<a href="'.$checkout_url.'?add-to-cart='.$current_product_id.'" class="buy-now button">Köp nu</a>';
      //echo '<a href="'.$checkout_url.'" class="buy-now button">Buy Now</a>';
        }
    }

add_content_after_addtocart();

?>

In code snippets it looks like this:

function add_content_after_addtocart() {
     
        // get the current post/product ID
        $current_product_id = get_the_ID();
     
        // get the product based on the ID
        $product = wc_get_product( $current_product_id );
     
        // get the "Checkout Page" URL
        $checkout_url = WC()->cart->get_checkout_url();
     
        // run only on simple products
        if( $product->is_type( 'simple' ) ){
            echo '<div class="clear-sec">';
            echo '</div>';
            echo '<a href="'.$checkout_url.'?add-to-cart='.$current_product_id.'" class="buy-now button">Köp nu</a>';
            //echo '<a href="'.$checkout_url.'" class="buy-now button">Buy Now</a>';
        }
    }
    add_action( 'generate_before_right_sidebar_content', 'add_content_after_addtocart' );

But in GP-hooks I remove the action and add it into a GP-hook instead.

I solved it! It was just a matter of removing the cache-plugin.

Hi there,

i can’t see any reason why it wouldn’t run.
As long as:

1. you have it wrapped in <?php // code here ?> tags
2. have checked execute PHP in the GP hook
3. have set the Display Rules so it only fires on pages where that code will work eg. Products

Then i can’t see any reason it would not work.

BUT…. i personally would not writher the function in the Hook element. Keep that in your child theme functions.php or code snippets. And only make the Callback in the Hook.

Glad to hear you got it working

I am on the hunt to find the best way to implement code on the website (and I find Child Themes a bit bothering, don’t you agree?). It seems WPCode with its conditional logic is a far stronger choice than your suggested Code Snippets. Since it is also free and offers full functionality that further makes it a better choice.

Your thoughts?

[David]

I have never used WPCode so i couldn’t advise on that.
Personally, i like child themes or in some cases writing a custom plugin.
If i were to list top reasons why, then ( scratching head ) i would say:

a. keep code in WP Admin to the bare minimum
b. provides a space for saving templates, fonts and media
c. can always access it via FTP
d. i edit the code directly in my IDE ( current fav their is VS Code )
e. easy to transfer to another site.

But this is just my preference. As those code snippets and wpcode plugins provide a lot of convenience and that has a lot of benefits for busy site builders.
