Mail In Both Plain Text And HTML At The Same Time!

[beaver6813]

Hey,

I was looking around for ages trying to get this damn thing working with thunderbird. Basically it sends an email using multipart/alternative which, if the email client supports MIME lets it decide whether to show the email in plain text or HTML.

Created By Beaver6813, a special thanks to Jonathan at The PHP Solution
 for all your help along the way.
 CHANGES:
 -- Is Now Compatible With GMail 
 -- Encrypts Messages In Base64 For Easier Transportation
 NOTES:
 -- From experience with different mail services i've discovered some key pointers
 when sending html or any type of email:
  * DO NOT link to external CSS stylesheets, most of the time these are either filtered out
  or do not load properly
  * As discovered in GMail it strips out any stylesheets completely, even inline ones so you're
  going to have to use the style='' tags on any div's etc you want to make look pretty
  * Bear in mind linking to any external resources will bring up a warning on the clients
  end and they can choose to or not to load external resources.
  * Keep HTML resources as simple as possible, most of the time they aren't loaded as well as
  they would in firefox and so can be really mucked up if you do some complicated magic with 
  them.
 COMING SOON:
 -- Will be turned into a class making it easier to send emails :)

Any comments or suggestions just lemme know here

EDIT:
Updated: Plain and HTML versions can now be defined in the $email_html and $email_plain variables
UPDATED 17/02: USE THIS VERSION! This is much more compatible with different mail services, see notes at top of code for more info

Rep or $NP Appreciated As Always :hehe:

Great job beaver, very helpful!

An easier way to give both parts of the message would be nice.
I never knew you could do that, but I knew you could send HTML. :o

Updated script above I'm personally using this to send out confirmation emails and what not so you dont have to ask initially whether they just want plain or HTML. Then after they confirm etc ill give them the option to decide whether to have it in plain or html on its own

I :hearts: multipart/alternative

 

[DylanButler]

Will use this, thanks

edit: also be sure to verify this will work on your server as many large hosting companies (dreamhost included) have been disabling the 4th parameter (headers) on mail().

 

[beaver6813]

Will be updating script soon.. gmail didnt like this version so i rewrote for a script i am currently working on I'll cut out the script and update it asap

 

[Barrucadu]

I was wondering how to do that, well well, the wonders of e-mail headers! lol

 

[beaver6813]

MAJOR UPDATE! Read updated first post for more info!

Is now compatible with Gmail and other services.

Well if they disable headers a) it makes it very hard to send out valid emails
b) i can't do anything about it :P having just the to, subject and message field is madness if you want to send out a decent email... they really should just filter out specific variables used for spoofing But.. meh!

Thanks for sharing. Great...

Ya there's nothing you can do about it. However, hosts are doing it and we will have to account for it nonetheless.
