How to Translate Title and Description Based on Site Language

Hello,

I am using Osclass and I would like to know how to translate the Page Title and Page Description based on the language the user is browsing the site in. Currently, the title and description are displayed statically, but I want them to change according to the selected language.

For example:

If the user is browsing the site in Arabic, the title and description should appear in Arabic.
If the user is browsing the site in French, the title and description should appear in French.
And for any other language, the title and description should be shown in that language.
Can I translate these fields by adding translations in the theme's translation file or in the site settings? What is the best way to ensure the title and description are shown in the appropriate language?

Not possible.
You need seo plugin or customization.

All in one SEO plugin or SEO pro plugin

Any plugin will work, one or another.

Where can I find the code and modify it to fix the problem?

Hello,

It's not optimal, but it works by modifying 3 files

There is an easier way. In the theme's head.php, change the following:
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<title><?php echo meta_title(); ?></title>
<meta name="title" content="<?php echo osc_esc_html(meta_title()); ?>" />
<?php if( meta_description() != '' ) { ?><meta name="description" content="<?php echo osc_esc_html(meta_description()); ?>" /><?php } ?>
<?php if( osc_get_canonical() != '' ) { ?><link rel="canonical" href="<?php echo osc_get_canonical(); ?>"/><?php } ?>
<meta http-equiv="Pragma" content="no-cache">
<meta http-equiv="Cache-Control" content="no-cache" />
<meta http-equiv="Expires" content="Mon, 01 Jul 1970 00:00:00 GMT" />
<?php if( !osc_is_search_page() )  { ?>
<meta name="robots" content="index, follow" />
<meta name="googlebot" content="index, follow" />
<?php } ?>
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0" />
With this:

<meta http-equiv="Content-type" content="text/html; charset=utf-8" />

<?php
$current_locale = osc_current_user_locale(); 

// Define a secondary dynamic title and description based on the language. The primary language is set via the ADMIN panel. 
if ($current_locale == 'en_US') {
