Question

I am getting this error when running my page through the W3C validator:

= in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.

Here is the code that is causing this error:

$prevPage = "?main=men&category1=1&pagenum=$prevp"."&lowRowNum=$prev_page_low".
                    "&highRowNum=$prev_page_high";

print("<a class='left' href=$prevPage>".
                    "Previous Page</a>&nbsp;&nbsp;&nbsp;");

I am not getting any error like this in any of my other PHP scripts , so I am guessing it is something specific I am doing wrong here?

Can anyone see why this code is causing this error?

I have researched this and read that it may be down to HTML special characters? I am not sure..

Thank you

Simply try:

<a class='left' href='$prevPage'>

Notice the quotes. Always try to quote your attributes in HTML. Better practice would be to:

echo '<a class="left" href="' . $prevPage . '">' //etc etc;

Try not to echo the entire HTML string as you might get confused when using single vs. double quotes.
