I disabled the Wordpress function 'Show comments cookies opt-in checkbox, allowing comment author cookies to be set.' but I added a checkbox in the comment form manually because I wanted to change the label of the checkbox.

I did this by adding the following code to the functions.php of my child theme:

add_filter( 'comment_form_default_fields', 'tu_comment_form_change_cookies_consent' );
function tu_comment_form_change_cookies_consent( $fields ) {
    $commenter = wp_get_current_commenter();

    $consent   = empty( $commenter['comment_author_email'] ) ? '' : ' checked="checked"';

    $fields['cookies'] = '<p class="comment-form-cookies-consent"><input id="wp-comment-cookies-consent" name="wp-comment-cookies-consent" type="checkbox" value="yes"' . $consent . ' />' .
                     '<label for="wp-comment-cookies-consent">By using this comment form you agree with our Privacy Policy</label></p>';
    return $fields;


This is working fine but now I wanna have this checkbox mandatory so that the user has to check it before pressing the 'Post comment' button.

So if the checkbox is unchecked, the user should see a error message when clicking on the 'Post comment' button.

How can I do that? All the suggestions I found so far are not working, like for example adding 'required' behind the input id or name.

Thanks for your help!

我禁用了Wordpress功能'显示评论cookie选择复选框,允许设置评论作者cookie。' 但我手动在评论表单中添加了一个复选框,因为我想更改复选框的标签。


函数tu_comment_form_change_cookies_consent($ fields){
 $ commenter = wp_get_current_commenter(); 
 $ consent = empty  ($ commenter ['comment_author_email'])?  '':'checked =“checked”'; 
 $ fields ['cookies'] ='&lt; p class =“comment-form-cookies-consent”&gt;&lt; input id =“wp-comment-  cookies-consent“name =”wp-comment-cookies-consent“type =”checkbox“value =”yes“'。  $同意。  '/&gt;'  。
'&lt; label for =“wp-comment-cookies-consent”&gt;使用此评论表单即表示您同意我们的隐私政策&lt; / label&gt;&lt; / p&gt;'; 
返回$ fields; 

这个工作正常,但现在我想强制使用此复选框,以便用户在按“发表评论”按钮之前必须检查它。 / p>


我该怎么做 ? 到目前为止我找到的所有建议都没有用,例如在输入ID或名称后添加'required'。

    There is a filter hook just before comment data is set. It is preprocess_comment. In that hook I have checked if the checkbox is set or not. If not it will block to post comment data.

    function wpso_verify_policy_check( $commentdata ) {
        if ( 'post' === get_post_type( $_POST['comment_post_ID'] ) ) {
            if ( ! isset( $_POST['wp-comment-cookies-consent'] ) ) {
                wp_die( '<strong>' . __( 'WARNING: ' ) . '</strong>' . __( 'You must accept the Privacy Policy.' ) . '<p><a href="javascript:history.back()">' . __( '&laquo; Back' ) . '</a></p>');
        return $commentdata;
    add_filter( 'preprocess_comment', 'wpso_verify_policy_check' );

    Edit: Added post type conditional so that this check is applied to post post type only.
