php - Wordpress 自定义联系表不起作用

Question

我正在尝试为我的 Wordpress 主题创建自定义联系表单页面。但是，在我完成代码的过程中，页面上的错误消息不会显示。

此外，我在本地主机上运行以测试此自定义页面，它似乎不会将我的消息发送到在我的 Wordpress 安装中设置的 ADMIN EMAIL。

这是我的 WP Custom Contact Form 上的片段:

<?php 
    /* Template Name: Contact Page */
?>


<?php 

    // Function for email address validation
    function isEmail($verify_email) {

        return(preg_match("/^[-_.[:alnum:]]+@((([[:alnum:]]|[[:alnum:]][[:alnum:]-]*[[:alnum:]])\.)+(ad|ae|aero|af|ag|ai|al|am|an|ao|aq|ar|arpa|as|at|au|aw|az|ba|bb|bd|be|bf|bg|bh|bi|biz|bj|bm|bn|bo|br|bs|bt|bv|bw|by|bz|ca|cc|cd|cf|cg|ch|ci|ck|cl|cm|cn|co|com|coop|cr|cs|cu|cv|cx|cy|cz|de|dj|dk|dm|do|dz|ec|edu|ee|eg|eh|er|es|et|eu|fi|fj|fk|fm|fo|fr|ga|gb|gd|ge|gf|gh|gi|gl|gm|gn|gov|gp|gq|gr|gs|gt|gu|gw|gy|hk|hm|hn|hr|ht|hu|id|ie|il|in|info|int|io|iq|ir|is|it|jm|jo|jp|ke|kg|kh|ki|km|kn|kp|kr|kw|ky|kz|la|lb|lc|li|lk|lr|ls|lt|lu|lv|ly|ma|mc|md|me|mg|mh|mil|mk|ml|mm|mn|mo|mp|mq|mr|ms|mt|mu|museum|mv|mw|mx|my|mz|na|name|nc|ne|net|nf|ng|ni|nl|no|np|nr|nt|nu|nz|om|org|pa|pe|pf|pg|ph|pk|pl|pm|pn|pr|pro|ps|pt|pw|py|qa|re|ro|ru|rw|sa|sb|sc|sd|se|sg|sh|si|sj|sk|sl|sm|sn|so|sr|st|su|sv|sy|sz|tc|td|tf|tg|th|tj|tk|tm|tn|to|tp|tr|tt|tv|tw|tz|ua|ug|uk|um|us|uy|uz|va|vc|ve|vg|vi|vn|vu|wf|ws|ye|yt|yu|za|zm|zw)$|(([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5])\.){3}([0-9][0-9]?|[0-1][0-9][0-9]|[2][0-4][0-9]|[2][5][0-5]))$/i",$verify_email));

    }

            $receiver_email = get_option('admin_email');

            $headers .= "Content-Transfer-Encoding: quoted-printable" . PHP_EOL;

有什么想法吗？或者如果您看到一些错误，有没有办法可以更正我的代码？

Answer 1

让你开始

1. 确保在您的 wp-config.php 文件中将 WP_DEBUG 设置为 true。
2. 您可以从 mail() 获取最后的错误(已回答 here)
3. 如果可用，请使用 wordpress 的功能，在本例中为 wp_mail随时为您服务。
4. 有 wordpress 插件，例如 gravity forms 或 contact form 7 可以完成任务。
5. 使用过滤器和操作。
