I've got TEXT_MAIN being displayed on my page
An uppercase set of words akin to
SOMETHING_LOOKING_LIKE_THIS is called a “constant” in PHP language terms.
define() statement is used to declare a constant.
This is what Zen Cart currently uses to build language output content, among other things.
Commonly you’ll see language definitions in the form of:
define('TEXT_MAIN', 'Something to display here');
Then, in a template file or somewhere else in the system, there will be a request to display the contents of
TEXT_MAIN, often in a PHP “echo” statement, but could be in many other forms too.
If the constant
TEXT_MAIN hasn’t been defined anywhere, or if the file in which it is defined has a syntax error above where it’s defined (causing it to not get defined), then the name of the constant will be displayed instead of the defined content.
If you’re seeing
TEXT_MAIN on your screen instead of regular normal language words, then somewhere in your files is a request to display the value defined to the
TEXT_MAIN constant, but, since you don’t have it defined, you’re seeing the constant name instead.
You have to find out where it was supposed to be defined, and fix it.
80% of the time this is a cause of someone editing a language file and “deleting” define statements that they don’t want to display, instead of just deleting the text that’s currently being displayed. ie: instead of just deleting the line altogether if they don’t like what TEXT_MAIN was defined to in the first place, one should use something like this to make it display “nothing”:
10% of the time it’s a result of a syntax error where a define statement earlier in the file has mismatched quotation marks, or a
; has been dropped.
10% of the time it’s because you’ve failed to upload the language file altogether, and thus the define is missing.
You might start with checking which files you’ve edited recently or contributions you’ve added, or compare your files vs a fresh set of Zen Cart files.
In your post, please include your Zen Cart and PHP versions, and a link to your site.
