Re: Re: Formatting

Ethan, is this valid PHP? What is the ampersand for? What is it doing? Just curious. $args[] = &$_POST[$k]; // Note the addition of the ampersand here Karl On Nov 26, 2012, at 12:14 AM, Matt Pelmear wrote:

FYI, this really is not the appropriate mailing list for these types of questions. Are you positive they are empty lines? i.e., are they in the html code of the page, or only appear as empty space in the rendered page? If they are just in the rendered page, in addition to losing the "</div>" in the middle of your table (as someone has suggested), you might also want to check your stylesheets. In particular, this looks like it could cause some strange things to happen depending on what you're doing with it: <td class="first-col"> Try loading up firebug and looking at the table element and the elements around it to see if there is some strange padding. Or, try disabling any stylesheets you are loading with the page to see if it still renders in an undesirable way. Good luck, -Matt On 11/25/2012 07:05 PM, Jim Giner wrote:

Help and advice, please Ethan

If this is the ACTUAL code you are executing you need to remember to NOT include any blank lines. Each and every one gets echoed to the client and with all the blank lines I see above, that could very well be a full but empty page.

+++++++++++++ Jim - Thank you. I removed all the blank lines, and get the same behavior. Ethan Ethan

I see nothing in this code but you really should do some more debugging. Add some echos all around in your script so you can see where the blank lines are coming from. Come on - we can't do your work for you - you have to be creative and find a way to isolate and identify your problem.
