What you mean when you say "I'm not able to use hooks"?

Here is the example - you need to add following code to your current theme's functions.php file and adjust the field name and code according to your needs:

add_filter('cred_form_validate','func_validate_taxonomy_select',10,2);
function func_validate_taxonomy_select($error_fields, $form_data)
{
    //field data are field values and errors
    list($fields,$errors)=$error_fields;
    //uncomment this if you want to print the field values
    //print_r($fields);
    //validate if specific form
    if ($form_data['id']==12)
    {
        //check my_field value
        if ($fields['wpcf-my_field']['value']!='correct_value')
        {
            //set error message for my_field
            $errors['wpcf-my_field']='Wrong Value';
        }
        //check if featured image exists
        if (empty($fields['_featured_image']['value']))
        {
            //set error message for featured image
            $errors['_featured_image'] = 'Missing featured image';
        }
    }
    //return result
    return array($fields,$errors);
}

I mean that I would really like to understand how to insert Hooks.

in your example there are items to change to adapt to my needs
example: id form.

where can I find a guide to learn how to use Hooks ONLY?

thank you

I already shared the Doc link before for the hook Doc:
=> https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_validate
[Click on "+ More" button to see examples ]

You can find CRED form ID when you edit your CRED form in URL.

Thanks Minesh,
I solved with the code you gave me

it would be nice to be able to CHANGE the field name in the error message.
It's not nice to see, example: "featured image error"
