Wordpress mail

WordPress has a built-in function to send emails using the wp_mail() function. Here's an example of how to use it:

wp_mail( '[email protected]', 'Subject', 'This is the email body' );

In this example, wp_mail() is used to send an email to [email protected] with the subject "Subject" and the body "This is the email body".

You can also add additional parameters to wp_mail() to customize the email, such as:

headers: an array of additional headers to add to the email
attachments: an array of file paths to attach to the email
content_type: the content type of the email (e.g. "text/plain" or "text/html")

Here's an example of how to use these additional parameters:

wp_mail( '[email protected]', 'Subject', 'This is the email body', array(
    'From' => '[email protected]',
    'Reply-To' => '[email protected]'
), array('file1.txt', 'file2.txt'), 'text/plain' );

In this example, the email is sent from [email protected] and the recipient can reply to the email by sending it back to [email protected]. The email also includes two attachments, file1.txt and file2.txt, and the content type is set to "text/plain".

You can also use the wp_mail() function to send emails with HTML content by setting the content_type parameter to "text/html". Here's an example:

wp_mail( '[email protected]', 'Subject', '<html>This is the email body</html>', array(
    'From' => '[email protected]',
    'Reply-To' => '[email protected]'
), array('file1.txt', 'file2.txt'), 'text/html' );

In this example, the email is sent with HTML content and the content type is set to "text/html".

It's also worth noting that you can use the wp_mail() function to send emails with attachments by using the wp_mail_attachment() function. Here's an example:

wp_mail_attachment( '[email protected]', 'Subject', 'This is the email body', 'file.txt' );

In this example, the email is sent with the attachment file.txt.

You can also use the wp_mail() function to send emails with multiple attachments by using the wp_mail_attachment() function multiple times. Here's an example:

wp_mail_attachment( '[email protected]', 'Subject', 'This is the email body', 'file1.txt' );
wp_mail_attachment( '[email protected]', 'Subject', 'This is the email body', 'file2.txt' );

In this example, the email is sent with two attachments, file1.txt and file2.txt.

It's also worth noting that you can use the wp_mail() function to send emails with a custom from name and email address by using the wp_mail_from_name and wp_mail_from_email filters. Here's an example:

add_filter( 'wp_mail_from_name', 'custom_from_name' );
add_filter( 'wp_mail_from_email', 'custom_from_email' );

function custom_from_name( $from_name ) {
    return 'Custom From Name';
}

function custom_from_email( $from_email ) {
    return '[email protected]';
}

In this example, the wp_mail_from_name and wp_mail_from_email filters are used to set the from name and email address to "Custom From Name" and "[email protected]" respectively.

It's also worth noting that you can use the wp_mail() function to send emails with a custom subject by using the wp_mail_subject filter. Here's an example:

add_filter( 'wp_mail_subject', 'custom_subject' );

function custom_subject( $subject ) {
    return 'Custom Subject';
}

In this example, the wp_mail_subject filter is used to set the subject of the email to "Custom Subject".
