=====phplist Coding Style Guidelines=====
 
Please use the following guidelines when developing code for phplist.

===PHP Code===
	-Use long-format code escaping: %%(php)<?php. . .?>%% (manual page: [[http://www.php.net/manual/en/language.basic-syntax.php]])
	-Use ##echo## to output all data, and don't forget the semi-colon:%%(php)<?php echo $mydata; ?>%%
	-Add newlines ##""(\n)""## after output lines, to help debug the output.
	-When embedding variables in
	-Make sure you properly quote array keys, i.e. %%(php)$array['key']%% and **NOT** %%(php)$array[key]%%
This latter syntax is [[http://www.php.net/manual/en/language.types.array.php improper code according to the manual]] (see "Array Do's and Don'ts") //and// has been broken with at least one PHP release (during 2003).

===HTML Code===
	-Aim for XHTML Strict output.
		-All tags and attributes in lower-case.
		-Put all attribute values in double-quotes.
		-Close all tags, including stand-along tags like %%(html4strict)<br />%%
	-Use CSS positioning except for tabular data.
	-Web browser compatibility:
		-Verify all output using the W3 validator: [[http://validator.w3.org/]]
		-Start testing with a Gecko-based browser (Mozilla, Firefox, ""K-Meleon"", etc) then verify with IE, Opera, Safari, etc.
	-Forms:
		-Include both the 'name' and 'id' attributes on all form fields.
		-Include accessibility features:
			-tabindex.
			-label.
