Question

我在下面的函数中添加了两个额外的字段，工作正常（名称和数字字段），但是我想在提交按钮之前添加一个额外的字段，但无论我在哪里添加它都会出错。

你能告诉我我添加的代码有什么问题：

<input type="text" placeholder="'.__('Questions or comments: (required)','dt_themes').'" name="quescomms" required>';

对于此功能以及如何正确添加它，并添加＆＃34;添加到订阅者列表？勾选＆＃34;在提交按钮之前？

这是我的代码（请参阅给出错误的输入部分）：

function dt_sc_subscription_form( $atts, $content = null ) {
    extract(shortcode_atts(array(
        'image_url' => '',
        'slider' => '',
        'slider_id' => '',
        'title'  => __('Plan a Visit', 'dt_themse'),
        'submit_text' => __('Submit', 'dt_themes'),
        'success_msg' => __('Thanks for subscribing, we will contact you soon.', 'dt_themes'),
        'error_msg' => __('Mail not sent, please try again Later.', 'dt_themes'),
        'subject' => __('Subscription', 'dt_themes'),
        'admin_email' => get_bloginfo('admin_email'),
        'enable_planavisit' => 'true',
        'contact_label' => __('Inquiries', 'dt_themes'),
        'contact_number' => ''
    ), $atts));
    if($admin_email == '') $admin_email = get_bloginfo('admin_email');

$out = '';

$out .= '<div class="column dt-sc-two-third no-space">  
            <div class="dt-sc-subscription-frm-image">';

                if($image_url != '') {                          
                    $out .= '<img src="'.$image_url.'" alt="'.$title.'" title="'.$title.'">';
                } else if($slider != '' && $slider_id != '') {
                    if($slider == 'LayerSlider') {
                        $out .= do_shortcode("[layerslider id='{$slider_id}']");
                    } elseif($slider == 'RevolutionSlider') {
                        $out .= do_shortcode("[rev_slider $slider_id]");
                    }
                }

您不能只将原始HTML写入PHP代码。也许你打算做这样的事情：

$out .= '<input type="text" placeholder="'.__('Questions or comments: (required)', 'dt_themes').'" name="quescomms" required>';

如何向函数添加其他字段？
