W3C errors on PHP URL String variables

Maybe I did not clearly explain the problem.  I continued to work on a solution and have now resolved the problem.

Here is the old URL Link that worked on the page, but produced a W3C error (online w3c check of the host page) followed by the new link that uses php variables for the string variables.

• Link that has W3C error: <a href="http://mlsonlinecr.com/mlshomesforsale_page.php?company_id=010002&type=%25&city=%25&provin ce=%25">Homes</a>
• Link that has NO W3C errors and sucessfully links to the URL:  <a href="http://mlsonlinecr.com/mlshomesforsale_page.php<?php echo "?company_id=" . $company_id . "&type=" . $all_values . "%25&city=" . $all_values . "&province=" . $all_values ; ?>">Homes</a>

Hope this clarifies things.   With the above change, The problem is now solved.

As PZ said, W3C validation is useless on raw PHP code.  You need to check the Live Code.

Assuming you have a local PHP development environment set-up in CC 2017,  open your PHP document.  Go to View > Live Code.  This will parse the PHP code and display the document as one would see it in a browser on the server.

Go to Window > Results > Validation.

Click the triangle to check Live Document.  See screenshot.

Just to be clear, the W3C checker does not see your PHP code, unless the code is not correctly contained within code tags.

You may want to use the PHP functions urlencode and urldecode on your urls to make sure the urls don't contain anything that will break. I do see a blank space in provin ce, which would be a problem.

You cannot.

The W3C checker can only check html or css code, and flags anything else as an error. To check your html or css then you will have to do this before inserting the php code, or ignore errors that you know are php code.
