Load/exclude scripts on specific pages/slugs (with wildcard)

Hi there,

There’s a filter called generate_element_display you can use for this. Reference: https://docs.generatepress.com/article/generate_element_display/

Usually, a conditional code like get_locale() == 'en' is used in conjunction with the filter for these instances.

Example snippet:

add_filter( 'generate_element_display', function( $display, $element_id ) {
    if (1234 === $element_id && get_locale() == 'en') {
        $display = true;
    } else if (5678 === $element_id && get_locale() == 'es') {
        $display = true;
    } 

    return $display;
}, 10, 2 );

You’ll need to replace 1234 and 5678 with the Element ID of the respective Element.

Adding PHP: https://docs.generatepress.com/article/adding-php/#code-snippets

Getting the Element ID: https://share.getcloudapp.com/YEuDdrnQ

You’ll need to check if that conditional statement will work for the plugin you used for the language change.

What plugin are you using for the language? Let’s see what needs to be altered for the conditional statement to work.

Are you using the paid version of that plugin? If so, they have a way to check the current plugin used through a code like this:

$current_lang = isset($_SERVER['HTTP_X_GT_LANG']) ? $_SERVER['HTTP_X_GT_LANG'] : '';

Reference: https://docs.gtranslate.io/en/articles/1349939-how-to-detect-current-selected-language#:~:text=Detecting%20current%20language%20for%20paid%20versions

Can you first create a Hook Element with this code:

<?php

$current_lang = isset($_SERVER['HTTP_X_GT_LANG']) ? $_SERVER['HTTP_X_GT_LANG'] : '';
var_dump($current_lang );

?>

Hook it to before_header.

Make sure to enable PHP in the Hook settings, and set the display rule to the entire site.

It’s best to do this on a staging site.

Let us know what appears on top of the page on an en and es page.

This way, we can construct a code that would have an appropriate conditional statement.

Hi there,

is that all that gets displayed on the site with Fernandos code ?

Ok, so if you make a note of the string values for each language then you can include them in the function like so:

add_filter( 'generate_element_display', function( $display, $element_id ) {
    $current_lang = isset($_SERVER['HTTP_X_GT_LANG']) ? $_SERVER['HTTP_X_GT_LANG'] : '';
    if (8790 === $element_id && $current_lang == 'and') {
        // display false if lang property contains and
        $display = false;
    } 
    return $display;
}, 10, 2 );

Yes, just expand the code. Example code:

add_filter( 'generate_element_display', function( $display, $element_id ) {
    $current_lang = isset($_SERVER['HTTP_X_GT_LANG']) ? $_SERVER['HTTP_X_GT_LANG'] : '';
    if (8790 === $element_id && $current_lang == 'en') {
        // display false if lang property contains en
        $display = false;
    }  else if (8791 === $element_id && $current_lang == 'fr') {
        // display false if lang property contains fr
        $display = false;
    }
    return $display;
}, 10, 2 );

You’re welcome!
