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',

   ]
]);

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, arrayCake\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.
arrayCake\Mailer\AbstractTransport|null $config optional: Either an array of configuration data, or a transport instance.

createFromArray(array $config): $this

Configures an email instance object from serialized config.

Parameters

array $config: Email configuration array.

Returns

$this

createView(string|null $viewClass = null): Cake\View\View

Constructs the view class instance based on the current configuration.

Parameters

string|null $viewClass optional: Optional namespaced class name of the View class to instantiate.

Returns

Throws

Cake\View\Exception\MissingViewException
If view class was not found.

Parses a DSN into a valid connection configuration

This method allows setting a DSN using formatting similar to that used by PEAR::DB. The following is an example of its usage:

$dsn = 'mysql://user:pass@localhost/database?';
$config = ConnectionManager::parseDsn($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.

Note that querystring arguments are also parsed and set as values in the returned configuration.

Saves a variable or an associative array of variables for use inside a template.

Parameters

string|array $name: A string or an array of data.
mixed $value optional: Value in case $name is a string (which then works as the key). Unused if $name is an associative array, otherwise serves as the values to $name's keys.

Returns

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',
     'contentDisposition' => false
   ]
]);

Attach a file from string and specify additional properties:

$email->setAttachments(['custom_name.png' => [
     'data' => file_get_contents('path/to/file'),
     '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.

string|array $attachments: String with the filename or array with filenames

$this

Throws

InvalidArgumentException

setConfig() ¶ public static

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

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

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:

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

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

Returns

void

Throws

BadMethodCallException
When trying to modify an existing config.
LogicException
When trying to store an invalid structured config array.

setConfigTransport() ¶ public static

setConfigTransport(string|array $key, arrayCake\Mailer\AbstractTransport|null $config = null): void

Sets 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 class name

Parameters

string|array $key: The configuration name to write. Or an array of multiple transports to set.
arrayCake\Mailer\AbstractTransport|null $config optional: Either an array of configuration data, or a transport instance. Null when using key as array.
