By default the Mass Mailer in Dolphin 7 Administration is very basic and simple. On top of that the area to actually type in is so small you can barely see anything.

This tutorial will show you how to switch it to the Advanced editor with more features. It will also show you how to increase the size so you can actually see what you are typing.

The current version at the time of this post is: Dolphin 7.0.7

First you will need to download and backup the following files just in case you mess up:
/administration/notifies.php
/administration/templates/base/css/forms_adv.css

How to switch Simple Editor to Advanced Editor

Now open /administration/notifies.php with some form of text editor and find:

'body' => array(
'type' => 'textarea',
'name' => 'body',
'value' => $sBody,
'caption' => $sBodyC,
'required' => true,
'html' => 1,
'checker' => array (
'func' => 'length',
'params' => array(10,32000),
'error' => $sErrorC,
),                   

Change to:

'body' => array(
'type' => 'textarea',
'name' => 'body',
'value' => $sBody,
'caption' => $sBodyC,
'required' => true,
'html' => 2,
'checker' => array (
'func' => 'length',
'params' => array(10,32000),
'error' => $sErrorC,
),                   

Then, save the changes back to your server / hosting account.

At this point if you go back to your Dolphin 7 Administration -> Tools -> Mass Mailer you should see the Advanced Editor.


If you would like to increase the height or width of the editor area you can continue reading the next section.

How to increase the Mass Mailer Editor height and width

Open /administration/templates/base/css/forms_adv.css with some form of text editor and find:

@import url(../../../../templates/base/css/forms_adv.css);

Simply add the following code under it:

.form_input_textarea {
border: none;
background-color: #ffffff;
width: 100%;
height: 357px;
resize: none;
}


The entire code would look like:

@import url(../../../../templates/base/css/forms_adv.css);

.form_input_textarea {
border: none;
background-color: #ffffff;
width: 100%;
height: 357px;
resize: none;
}


Save the changes back to your server / hosting account.


Note:
You can adjust the following to your desired width and height:
width: 100%;
height: 357px;

Example:

@import url(../../../../templates/base/css/forms_adv.css);

.form_input_textarea {
border: none;
background-color: #ffffff;
width: 500px;
height: 500px;
resize: none;
}
