Hello, I am trying to redefine meta tags for a web page and use this function function YOURTHEME_preprocess_html (& $ variables) {, I already realized that this does not work, but I have not found an analogue yet, how can I replace it?

template_preprocess_html() has been replaced by template_preprocess_page(), due to html.tpl.php being replaced by page.tpl.php: https://docs.backdropcms.org/change-records/htmltplphp-removed

Hello @MikheevDesign 👋

Thank you, I looked ngo in the meta tag module folder there is no such file, there is an API there, but only an example with a title
I apologize immediately, I did not figure it out, now I will understand and I will try, the link to the github is really useful in this case
I understand that this code no longer works function YOURTHEME_preprocess_html (& $ variables) {
// Set specific metatag description to Contact page, for avoiding
// Google Webmaster Tools warning about duplicate description with homepage
if (drupal_get_path_alias () == 'contact') {
$ metag = array (
'#type' => 'html_tag',
'#tag' => 'meta',
'#attributes' => array (
'name' => 'description',
'content' => 'Your contact page description here.',
),
);
drupal_add_html_head ($ metag, 'metatag_description_0');
}
}
even if using function template_preprocess_page (& $ variables), as soon as I add function backdrop_get_path_alias after this function, I get a "white screen". It's a pity that there are no examples of working with preprocessors.
The examples that I found in system themes are too simple, they just add style or a font.
I just can't figure out how to get the page address in the function template_preprocess_page, I tried it like this function template_preprocess_page (& $ variables) {
if (backdrop_get_path_alias ($ path = 'contact')) {to no avail, get error
Make sure you replace 'template' (in the function name) with your theme name, like you mentioned in your first post. For example:
YOURTHEME_preprocess_page(&$variables) {
if (backdrop_get_path_alias() == 'contact') {
// Set custom Metatags here...
}
}
I write that, but for some reason it does not work, I figured out the error, but the meta description is not displayed
function lateral_preprocess_page(&$variables) {
if (backdrop_get_path_alias() == 'contact') {
$metatag_description = array(
'#type' => 'html_tag',
'#tag' => 'meta',
'#attributes' => array(
'name' => 'description',
'content' => 'Your contact page description here.',
),
);
backdrop_add_html_head($metatag_description, 'description');
}
We don't have the function theme_html_tag in Backdrop, we've switched to using theme_head_tag instead: https://docs.backdropcms.org/change-records/themehtmltag-becomes-themehe...
Your code would need to look like this:
function lateral_preprocess_page(&$variables) {
if (backdrop_get_path_alias() == 'contact') {
$metatag_description = array(
'#type' => 'head_tag',
'#tag' => 'meta',
'#attributes' => array(
'name' => 'description',
'content' => 'Your contact page description here.',
),
);
backdrop_add_html_head($metatag_description, 'description');
}
}
I often like to look at examples of how this is done in core, so here's an example of the viewport head tag being added:
