A Craft CMS plugin. Grant your site users the power of communication, via private messaging!

##1. Send a private message

Add the following form to your template:

<form method="post" action="" accept-charset="UTF-8" id="privateMessagingSendForm">

    <input type="hidden" name="action" value="privateMessaging/message/saveMessage">
    <input type="hidden" name="redirect" value="/message-sent">
    <input type="hidden" name="senderId" value="{{ currentUser.id }}">
    <input type="hidden" name="recipientId" value="{{ recipientId }}">

    <label for="privateMessagingSubject">Subject</label>
    <input type="text" id="privateMessagingSubject" name="subject" value="">

    <label for="privateMessagingMessage">Message</label>
    <textarea id="privateMessagingMessage" name="body" form="privateMessagingSendForm" required></textarea>

    <input type="submit" value="Submit">
</form>

You will need to set the following form values:

• redirect - This should be set to the template to redirect to, upon successfully sending the private message
• senderId - This should be the ID of the user sending the message
• recipientId - This should be the ID of the user due to receive the message

##2. View messages

To view the logged in users messages, you will need to add the following to your template:

{% for message in privateMessages %}

{% endfor %}

Within this loop you can access the following private message attributes:

• message.id - The message ID. [type: integer]
• message.subject - The subject of the message. [type: string(255)]
• message.body - The body of the message. [type: text]
• message.sender - The sender user. [type: user object]
• message.recipient - The recipient user. [type: user object]
• message.isRead - Whether the message has been read. [type: boolean]
• message.dateCreated - The created dateTime of the message. [type: dateTime]

##3. View unread message count

To view the unread message count for the currently logged in user, you will need to add the following to your template:

{{ unreadPrivateMessageCount }}

##4. View total message count

To view the total message count for the currently logged in user, you will need to add the following to your template:

{{ totalPrivateMessageCount }}

##5. View a message

To access an individual message, you will need to pass the id of a message to your template.

This can be achieved by setting up a new route that passes the message id (number) to your template, like so:

Inside the template, we will use this ID (number) to retrieve the message, but, first we check to ensure we have actually been passed an ID:

{% if number is not defined %}
    {% exit 404 %}
{% else %}

If we have an ID, then we pass this to the getPrivateMessage method (which is a twig extension built into the plugin):

{% set message = number|getPrivateMessage %}

If this method does not return an associated message, it will return false. We may wish to handle that also:

{% if message == false %}
    {% exit 404 %}
{% endif %}

The getPrivateMessage method with return a false value when:

1. Out of range - A message with that ID doesn't exist in the database
2. Deleted - A message with that ID has been deleted from the database
3. Permissions - A message with that ID does not belong to the user trying to access it

##6. Delete a message

Add the following form to your template:

<form method="post" action="" accept-charset="UTF-8" id="privateMessagingDeleteForm">
    <input type="hidden" name="action" value="privateMessaging/message/deleteMessage">
    <input type="hidden" name="redirect" value="/messages">
    <input type="hidden" name="id" value="{{ message.id }}">
    <input type="submit" value="Delete">
</form>

You will need to set the following form values:

• redirect - This should be set to the template to redirect to, upon successfully deleting the private message
• id - This should be the ID of the message

NB: A user can only delete messages that belong to them.
