Changing font-lock for combined HTML and PHP code??

Changing font-lock for combined HTML and PHP code??

[William Case]

Hi;

I am working on web site made up of files that combine HTML and PHP.  My
main interest is in the PHP coding.  Is there a relatively easy way to
set the font-lock colors for the tags (constants) that distinguishes
between a HTML tag and a PHP tag when I am in php-mode. 

In case I am misusing terminology, by tag I mean expressions like
<p> ... </p> in HTML; <?php ... ?> in PHP.

Yes, perhaps. If you are using the Emacs 22 beta then you can use nXhtml:

    http://ourcomments.org/Emacs/nXhtml/doc/nxhtml.html

But at the moment I am working to fix some bugs, see the "News and Notes 
about nXhtml" at the top. I hope I can upload a new version the nearest 
days, ie version 0.98 (the latest upload is v 0.97).

The attached elisp file uses mmm-mode, psgml html mode, and php-mode
(which I obtained from Debian or via a google search) to make it do what
you want.  I have not used the php stuff in there very much, so it will
probably need a small amount of work.

I would like to find a good way to handle these kinds of files too,
with both html code and php code.
What I'm experimenting with just now is adding a keyboard setting for
the html-mode to go to php mode and keyboard setting for php mode to
go to html mode. Not ideal but better than what I had before which was
treating php-files like html-files, hehe. I like emacs' html mode. I
downloaded php mode from a third party.

The code is simply:

(require 'php-mode)

; php-mode actually runs this hook, maybe there's a better place to
put this...
(defun my-c-mode-common-hook ()
  (define-key c-mode-base-map "\C-c\C-h" 'html-mode)
)
(add-hook 'c-mode-common-hook 'my-c-mode-common-hook)


(defun my-html-mode-hook ()
  (define-key html-mode-map "\C-c\C-p" 'php-mode)
)
(add-hook 'html-mode-hook 'my-html-mode-hook)

The php-mode will actually font lock the html code but I don't like
the way it indents it at all. Thus I switch between the modes with
these keyboard bindings depending on if I'm editing a html part of the
file or a php part. As I said, not ideal, but better than my earlier
approach.

Hi Eric;

Since I am just starting on this HTML/PHP journey I may misspeak but ...

Since all the HTML tags are in the form <x> </x> i.e. double angle
brackets, it seems to me I should be able to add a definition somewhere
(where ?) that gets added to a php-mode font-lock mode and assigns a
special meaning and colour to expressions with double angle brackets.

At the moment I am using the global font-locks, so I would have to
create (or edit)
a php-mode font-lock using an amended global font-lock as my template.  

(Easy to say.  Doing is another thing.)

On second thought, it doesn't matter if HTML constants are always shown
in readable yellow while PHP show up in Orange in a global setting.

As I say, my concentration is on the PHP so I only need to differentiate
between PHP and the beginning and ending of a block of HTML.  I don't
need a full different set of syntatical font-locks for HTML.

I would suggest trying nxhtml - it has come on a lot recently and
Lennart is sufficiently motivated to support it. The whole html/php/css
situation is a bit of a mess for emacs at the moment - too many
competing hacks. nxhtml is quite a nice solution to all that.

Thanks for the kind words. But please hold on for a couple of hours if 
you want to test nXhtml. I am currently trying to add an improvement for 
XHTML completion in PHP. I will tell here when I am ready.

Re: Changing font-lock for combined HTML and PHP code??

[William Case]

Thanks Lennart;

You know how it is.  I missed the meeting of our local LUG and got
appointed as one of the maintainers our website.  Have only done very
very basic web stuff before.

I'll wait until I see a posting.  The problem is we seem to have a
mishmash of html and php that started out as php rather than the other
way around.  First, I need something that is just easy to update the
site with current information. 

We use subversion for updating.  In the longer term I think everything
has to be re-done but right now it is all *.php files with HTML tags and
code mixed in.  By the way, there is nothing wrong with the look of our
LUG site but the backend seems to be a dog's breakfast.

Did you ever get the nXhtml program completed ?
If so could you let me know where to get a test copy?
