Wordpress 从页面中的简码获取属性

Question

我正在构建一个 wordpress 联系表单插件，当使用简码时输出一个简单的联系表单。短代码有​​一个属性recipient_email，这是用户希望所有电子邮件从表单转到的电子邮件地址。我正在尝试在我的 php 邮件程序文件中获取收件人电子邮件的值。

这是我的简码输出的 html 及其属性：

extract(shortcode_atts(array(
            'el_class' => '',
            'title' => '', 
            'subtitle' => '',
            'recipient_email' => '',
        ), $atts));

        $el_class = $this->getExtraClass($el_class);
        $css_class = apply_filters(VC_SHORTCODE_CUSTOM_CSS_FILTER_TAG,$el_class, $this->settings['base']);
        $subtitle = '<legend>'.$subtitle.'</legend>';           

        $output .= '<div class="contact-form '.$css_class.'" >';
        $output .= '<h4 class="form-title">'.$title.'</h4>';            

        $output .=  '<div id="contact">

        <div id="message"></div>

        <form method="post" action="'. VCPB_PLUGIN_URL . 'contact.php' .'" name="contactform" id="contactform">

        <fieldset>';

        $output .= $subtitle;

        $output .= '<label for="name" accesskey="U"><span class="required">*</span> Your Name</label>
        <input name="name" type="text" id="name" size="30" value="" />

        <br />
        <label for="email" accesskey="E"><span class="required">*</span> Email</label>
        <input name="email" type="text" id="email" size="30" value="" />

        <br />
        <label for="phone" accesskey="P"><span class="required">*</span> Phone</label>
        <input name="phone" type="text" id="phone" size="30" value="" />

        <br />
        <label for="comments" accesskey="C"><span class="required">*</span> Your message</label>
        <textarea name="comments" cols="40" rows="5" id="comments" style="width: 350px;"></textarea>

        <p><span class="required">*</span> Are you human?</p>

        <label for="verify" accesskey="V">&nbsp;&nbsp;&nbsp;3 + 1 =</label>
        <input name="verify" type="text" id="verify" size="4" value="" style="width: 30px;" /><br /><br />

        <input type="submit" class="submit" id="submit" value="Submit" />';
        $output .= '</fieldset>

        </form>

</div>';          
        $output .= '</div>'; /* END .contact-form */
        return $output; 

如您所见，表单中的信息被发送到contact.php，后者处理表单并通过电子邮件发送出去。

这是我的 php 邮件文件 (contact.php) 的主要部分：

$address = "$recipient_email";
$e_subject = 'You\'ve been contacted by ' . $name . '.';
$e_body = "You have been contacted by $name, their message is as follows." . PHP_EOL . PHP_EOL;
$e_content = "\"$comments\"" . PHP_EOL . PHP_EOL;
$e_reply = "You can contact $name via email, $email or via phone $phone";

$msg = wordwrap( $e_body . $e_content . $e_reply, 70 );

$headers = "From: $email" . PHP_EOL;
$headers .= "Reply-To: $email" . PHP_EOL;
$headers .= "MIME-Version: 1.0" . PHP_EOL;
$headers .= "Content-type: text/plain; charset=utf-8" . PHP_EOL;
$headers .= "Content-Transfer-Encoding: quoted-printable" . PHP_EOL;

if(mail($address, $e_subject, $msg, $headers)) {

// Email has sent successfully, echo a success page.

echo "<fieldset>";
echo "<div id='success_page'>";
echo "<h1>Email Sent Successfully.</h1>";
echo "<p>Thank you <strong>$name</strong>, your message has been submitted to us.</p>";
echo "</div>";
echo "</fieldset>";

} else {
echo 'ERROR!';
}

这里最重要的是我要解决的问题：

$address = "$recipient_email";

我希望 $recipient_email 成为输入短代码的值。谁能帮我弄清楚我会怎么做？

Answer 1

有两种方法可以做到这一点 要么通过隐藏的输入类型发送收件人（这不是一个好的选择）

或

将表单操作放在同一页面上，而不是放在contact.php上 在同一页面上，您可以使用 shortcode_atts 获取收件人电子邮件
