标签： php wordpress

我创建了一个页面模板并将其作为页面的主题。之后我选择了此页面作为二十七个主题选项中的页面部分，但是如果您直接访问该页面而不是页面部分，则不会显示此页面的内容。

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

<?php
if(isset($_POST['submitted'])) {
    if(trim($_POST['contactName']) === '') {
        $nameError = 'Please enter your name.';
        $hasError = true;
    } else {
        $name = trim($_POST['contactName']);
    }

    if(trim($_POST['email']) === '')  {
        $emailError = 'Please enter your email address.';
        $hasError = true;
    } else if (!preg_match("/^[[:alnum:]][a-z0-9_.-]*@[a-z0-9.-]+\.[a-z]{2,4}$/i", trim($_POST['email']))) {
        $emailError = 'You entered an invalid email address.';
        $hasError = true;
    } else {
        $email = trim($_POST['email']);
    }

    if(trim($_POST['comments']) === '') {
        $commentError = 'Please enter a message.';
        $hasError = true;
    } else {
        if(function_exists('stripslashes')) {
            $comments = stripslashes(trim($_POST['comments']));
        } else {
            $comments = trim($_POST['comments']);
        }
    }

    if(!isset($hasError)) {
        $emailTo = get_option('tz_email');
        if (!isset($emailTo) || ($emailTo == '') ){
            $emailTo = get_option('admin_email');
        }
        $subject = '[PHP Snippets] From '.$name;
        $body = "Name: $name \n\nEmail: $email \n\nComments: $comments";
        $headers = 'From: '.$name.' <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email;

        wp_mail($emailTo, $subject, $body, $headers);
        $emailSent = true;
    }

我希望你能帮助我们。提前致谢！ ：）

修改

直接访问页面时会显示包含自定义页面模板的网站，例如http://example.com/testing。

direct link

但是如果你想在主题选项下的二十七个主题中将其设置为页面部分，那么自定义模板应该出现的空间是空白的。如果您通过http://example.com访问它，就属于这种情况。该网站是onepager，带有自定义页面模板的测试页面是其中的一部分。

front page

第二次编辑：

我将自定义页面设置为页面部分，只需在主题选项中进行设置即可。

答案 0 :(得分：0)

您正在尝试使用wordpress中的wordpress函数。将此代码require_once($_SERVER['DOCUMENT_ROOT'] . '/wp-load.php');直接放在代码第8行的开始php代码<?php的下一行。

如果您的wordpress安装位于主服务器目录的某个文件夹中，则此功能可能无效。然后你可以尝试这个：

//place this at the same position, as I mentioned above
$needPath = realpath(__DIR__ . '/../../..');
require_once($needPath . '/wp-load.php');

来自here的已使用的解决方案在文件系统中提升了几个级别。因为我们需要从{wp-main-folder}/wp-content/themes/twentyseventeen/{your-file}转到主要的wordpress安装文件夹，所以我们应该向上移动3级以获取wp-load.php文件。

修改

此外，如果您的WordPress安装调用了您的页面，将会很有用。因此，您可以使用此解决方案：

//place this to the same place as described above
if(!defined(ABSPATH)) {
    $needPath = realpath(__DIR__ . '/../../..');
    require_once($needPath . '/wp-load.php');
}

经过测试和工作

从wordpress调用此模板。您需要将其称为（如果您的网站网址为http://example.com）：

从wordpress page创建dashboard，然后从template右侧的列表create page section中选择，而不是要使用的Default Template：

how it looks

之后（不要忘记添加page title）保存页面并转到url，在那里提供。如果网页没有parent，或永久链接为?p=123，那么您应该像以下网址一样访问该网页：http://example.com/your-page-title。

如果您要直接访问该模板，则应将url写为http://example.com/wp-content/themes/twentyseventeen/your-template-filename.php。此示例作为模板提供，直接位于twentyseventeen theme文件夹中。
