您可以尝试将此过滤器添加到主题的函数中。php：

add_filter(\'comment_form_default_fields\', \'remove_url\');
function remove_url($val) {
    $val[\'url\'] = \'\';
    return $val;    
}

要删除任何字段，您应该传递$args，其中包含要在表单中显示的字段。

示例：

<?php
    $args = array(
        \'fields\' =>array(
            \'author\' => \'<p class="comment-form-author">\' . \'<label for="author">\' . __( \'Name\' ) . \'</label> \' . ( $req ? \'<span class="required">*</span>\' : \'\' ) . \'<input id="author" name="author" type="text" value="\' . esc_attr( $commenter[\'comment_author\'] ) . \'" size="30"\' . $aria_req . \' /></p>\',
            \'email\' => \'<p class="comment-form-email"><label for="email">\' . __( \'Email\' ) . \'</label> \' . ( $req ? \'<span class="required">*</span>\' : \'\' ) . \'<input id="email" name="email" type="text" value="\' . esc_attr(  $commenter[\'comment_author_email\'] ) . \'" size="30"\' . $aria_req . \' /></p>\',
            // \'url\' => \'<p class="comment-form-url"><label for="url">\' . __( \'Website\' ) . \'</label>\' . \'<input id="url" name="url" type="text" value="\' . esc_attr( $commenter[\'comment_author_url\'] ) . \'" size="30" /></p>\',
        ); 
    );
    comment_form($args);

如果您想进一步了解如何使用function comment_form(); 你应该看看这个Codex page

转到wp content\\themes\\suffusion\\comments。php文件

suffusion是我的主题名称，您应该转到各自的主题文件夹

查找此代码块

comment_form(apply_filters(\'suffusion_comment_form_fields\', array(
        \'fields\' => array(
            \'author\' => $author_field,
            \'email\' => $email_field,
        //  \'url\' => $url_field,  // comment this field 
        ),
