Change the location of the tmp directory for SwiftMailer in Symfony2

问题

My shared hosting does not allow me to use the root \tmp directory.

I know that the location of the temp directory can be updated using the Swift_Preferences class, however, how do I do that for a SwiftMailer instance autoloaded by Symfony2?

Is there a way to set it in my config.yml?

I think the code should be:

\Swift_Preferences::getInstance()->setTempDir($newTempDir);

But how/where can I set this config?

回答1:

There is more than a one way to do this. However, I think the best place for that would be inside boot method of your "main" bundle.

.../My/WebsiteBundle/MyWebsiteBundle.php:

...

public function boot() {
    $tmpDir = $this->container->getParameter('my_website.swift_tmp_dir');

    \Swift_Preferences::getInstance()->setTempDir($tmpDir);
}

...

You can modify the whole parameter via a autoprepend.php script:

<?php
putenv('TMPDIR=/var/www/yourdir/tmp');

and set it in the .htaccess in your document root:

php_value auto_prepend_file /var/www/yourdir/htdocs/autoprepend.php
