How to assign a fixed value to a custom field - php

Question

hope someone can help. I found the following code on the web and it works well to create a new custom field which I can input from the WP 'users' tab. Yet I need to give this field manually a value in php instead trough an input form. Thanks!
function custom_user_profile_fields($user){
if(is_object($user))
$company = esc_attr( get_the_author_meta( 'company', $user->ID ) );
else
$company = null;
?>
<h3>Extra profile information</h3>
<table class="form-table">
<tr>
<th><label for="company">Company Name</label></th>
<td>
<input type="text" class="regular-text" name="company" value="<?php echo $company; ?>" id="company" /><br />
<span class="description">Where are you?</span>
</td>
</tr>
</table>
<?php
}
add_action( 'show_user_profile', 'custom_user_profile_fields' );
add_action( 'edit_user_profile', 'custom_user_profile_fields' );
add_action( "user_new_form", "custom_user_profile_fields" );
function save_custom_user_profile_fields($user_id){
# again do this only if you can
if(!current_user_can('manage_options'))
return false;
# save my custom field
update_user_meta($user_id, 'company', $_POST['company']);
}
add_action('user_register', 'save_custom_user_profile_fields');
add_action('profile_update', 'save_custom_user_profile_fields');

If you are looking to save a fixed value to each company field to the usermeta table in the WordPress database, you can modify your saving function, to provide a fixed value instead of the POST field, you are assigning in your code snippet right now.
update_user_meta(
user_id: $user_id,
meta_key: 'company',
meta_value: 'your-custom-fiexed-value-here', // <--- here you go
);
(using named parameters requires PHP ^8.0.0)
