Class Email

CakePHP Email class.

This class is used for sending Internet Message Format based on the standard outlined in https://www.rfc-editor.org/rfc/rfc2822.txt

Configuration

Configuration for Email is managed by Email::config() and Email::configTransport(). Email::config() can be used to add or read a configuration profile for Email instances. Once made configuration profiles can be used to re-use across various email messages your application sends.

Namespace: Cake\Mailer

Attach a file with a different filename:

$email->setAttachments(['custom_name.txt' => 'path/to/file.txt']);

Attach a file and specify additional properties:

$email->setAttachments(['custom_name.png' => [
     'file' => 'path/to/file',
     'mimetype' => 'image/png',
     'contentId' => 'abc123',

     'mimetype' => 'image/png'
   ]
]);

The contentId key allows you to specify an inline attachment. In your email text, you can use <img src="cid:abc123" /> to display the image inline.

The contentDisposition key allows you to disable the Content-Disposition header, this can improve attachment compatibility with outlook email clients.

config() ¶ public static

config(string|array $key, array|null $config = null): array|null

This method can be used to define configuration adapters for an application or read existing configuration.

To change an adapter's configuration at runtime, first drop the adapter and then reconfigure it.

Adapters will not be constructed until the first operation is done.

Usage

Assuming that the class' name is Cache the following scenarios are supported:

Reading config data back:

Cache::config('default');

Setting a cache engine up.

Cache::config('default', $settings);

Injecting a constructed adapter in:

Cache::config('default', $instance);

Configure multiple adapters at once:

Cache::config($arrayOfConfig);

Parameters

string|array $key: The name of the configuration, or an array of multiple configs.
array|null $config optional: An array of name => configuration data for adapter.

Returns

array|null

Throws

BadMethodCallException
When trying to modify an existing config.

configTransport() ¶ public static

configTransport(string|array $key, array|Cake\Mailer\AbstractTransport|null $config = null): array|null

Add or read transport configuration.

Use this method to define transports to use in delivery profiles. Once defined you cannot edit the configurations, and must use Email::dropTransport() to flush the configuration first.

When using an array of configuration data a new transport will be constructed for each message sent. When using a Closure, the closure will be evaluated for each message.

The className is used to define the class to use for a transport. It can either be a short name, or a fully qualified classname

Parameters

string|array $key: The configuration name to read/write. Or an array of multiple transports to set.
array|Cake\Mailer\AbstractTransport|null $config optional: Either an array of configuration data, or a transport instance.

Returns

array|null

Throws

BadMethodCallException
When modifying an existing configuration.

$config = ConnectionManager::parseDsn($dsn);

$dsn = 'Cake\Log\Engine\FileLog://?types=notice,info,debug&file=debug&path=LOGS';
$config = Log::parseDsn($dsn);

$dsn = 'smtp://user:secret@localhost:25?timeout=30&client=null&tls=null';
$config = Email::parseDsn($dsn);

$dsn = 'file:///?className=\My\Cache\Engine\FileEngine';
$config = Cache::parseDsn($dsn);

$dsn = 'File://?prefix=myapp_cake_core_&serialize=true&duration=+2 minutes&path=/tmp/persistent/';
$config = Cache::parseDsn($dsn);

For all classes, the value of scheme is set as the value of both the className unless they have been otherwise specified.

setAttachments() ¶ public

setAttachments(string|array $attachments): $this

Add attachments to the email message

Attachments can be defined in a few forms depending on how much control you need:

Attach a single file:

$email->setAttachments('path/to/file');

Attach a file with a different filename:

$email->setAttachments(['custom_name.txt' => 'path/to/file.txt']);

Attach a file and specify additional properties:

$email->setAttachments(['custom_name.png' => [
     'file' => 'path/to/file',
     'mimetype' => 'image/png',
     'contentId' => 'abc123',

Adapters will not be constructed until the first operation is done.

Usage

Assuming that the class' name is Cache the following scenarios are supported:

Setting a cache engine up.

Cache::setConfig('default', $settings);

Injecting a constructed adapter in:

Cache::setConfig('default', $instance);

Configure multiple adapters at once:

Cache::setConfig($arrayOfConfig);

Parameters

The className is used to define the class to use for a transport. It can either be a short name, or a fully qualified class name

Parameters
