Checking Links: While K-12math.info greatly appreciates comments from users on link problems (send to: k-12math(at)sbcglobal(dot)net ),
there is an ongoing program to check for link problems. Beyond the random checking that is done frequently, some great time saving
link checking utilities are used. Fortunately textbook publishers realize the need for stability.
All the pages you see are written in pure HTML code (efforts are being made to remove the CSS link); except one which is written in PHP code using a small MySQL table. The single PHP program is responsible for the 1000 screens of information that are given in options 2 to 8 on the left side of the Information screen. The writing and updating of 1000 HTML programs to equal what that one program yields would be a nightmare (unless you have half a dozen graduate students in need of …..). The PHP program insures a higher degree of accuracy in reporting the information.
Unfortunately the PHP program has one draw back.
When linked to from outside K-12math.info the screen displaces an empty spreadsheet.
DO NOT EXTERNALLY LINK TO THE SPREADSHEET (https://www.k-12math.info/einfo.php ).
The screens previous to the spreadsheet (options 2 to 8 on the left side of the Information screen)
send parameters to the PHP spreadsheet program which then constructs the spreadsheet with content information in it.
Doing a screen print is the best way to have a complete spreadsheet. (K-12math.info assumes the user knows that coping the spreadsheet to an Excel spreadsheet will carry the text and URL
with it.)
The use of HTML and PHP minimize the problems of adapting to different web operating systems.
It has been successful on all major browsers.
Hint: Sometimes it is faster to use your web browser's backup arrow to return to the previous page.
Please let me know if you encounter any problems. Jim Kelly at: k-12math(at)sbcglobal(dot)net
