表单在提交时尝试下载文件

时间：2017-02-03 作者：J Robz

所以我正在开发这个插件，以获取表单的输入，并将其放入。CSV文档，然后发送。通过电子邮件发送CSV文档。所有这些都很好。但是，按submit时，会下载一个名为“download”的rouge文件。当这个文件在我的文本编辑器中打开时，它似乎只是页面的编译代码。这很奇怪。以下是我的插件的源代码：

表单到csv。php

<?php

// Make sure we don\'t expose any info if called directly
if ( !function_exists( \'add_action\' ) ) {
    echo \'Hi there!  I\\\'m just a plugin, not much I can do when called directly.\';
    exit;
}

define( \'FORM_TO_CSV__VERSION\', \'1\' );
define( \'FORM_TO_CSV__MINIMUM_WP_VERSION\', \'4.7.2\' );
define( \'FORM_TO_CSV__PLUGIN_DIR\', plugin_dir_path( __FILE__ ) );
define( \'FORM_TO_CSV__DELETE_LIMIT\', 100000 );

register_activation_hook( __FILE__, array( \'Form_To_CSV\', \'plugin_activation\' ) );
register_deactivation_hook( __FILE__, array( \'Form_To_CSV\', \'plugin_deactivation\' ) );

require_once( FORM_TO_CSV__PLUGIN_DIR . \'form-to-csv_run.php\' );
以及form-to-csv\\u运行。php文件，我认为这就是问题所在

此外，它的功能屏幕截图：

the rouge download

而该文件在文本编辑器中显示的内容，我百分之百确定它就是im所在的页面：

the rouge download's source code

像往常一样，这可能只是某个地方的一个小错误，但我一直在努力解决这个问题。因此，任何帮助都将不胜感激。

更新时间：

我尝试删除“标题”行，并将“邮件”行更改为：

wp_mail($mailto, $subject, $header, \'\', $file);
而且它不会随机下载文件！它仍然发送电子邮件，但是现在csv文件没有附加。所以还是很不幸地被难住了。

最合适的回答,由SO网友:David Lee 整理而成

要将文件附加到电子邮件，您需要按如下方式指定文件的路径：

<?php
$attachments = array( WP_CONTENT_DIR . \'/uploads/file_to_attach.zip\' );
$headers = \'From: Test Name <[email protected]>\' . "\\r\\n";
wp_mail( \'[email protected]\', \'subject\', \'message\', $headers, $attachments );
?>
无论是字符串还是数组（对于多个文件），都可以在此处看到接受的参数wp_email. 不在标题中，我可以在这里看到：

$header .= "Content-Disposition: attachment; filename=\\"" . $FileName . "\\"\\r\\n\\r\\n"; // For Attachment

表单操作设置为空字符串。我认为这可能是问题的一部分。不是百分之百肯定，但希望这能有所帮助！

SO网友:Steve

只是一件小事，用wp_mail(); 而不是mail();

看看接下来会发生什么。

也不认为你需要header(\'Content-Type: application/csv\');.

将返回页面的页眉设置为CSV文件。CSV文件不能通过网页打开，而是下载文件。

该文件是否下载了CSV文件？
