Re: [PHP] What's wrong with this code?
Hello everyone,
Much thanks. Sometimes when you stare at code for so long it blurs
together, that's how it is with me at least. That was my problem, case
sensitive variable.
Thanks a lot.
Dave.

That's not the whole code, but it is the problem code. Some output has
the ending date set, one or two records i can't remember how many i
entered with one, most do not, i want the echo to be conditional. The
output stops right before the if statement, echoes startdate and
that's it, comment out the if block and it works fine.
Thanks.

Re: [PHP] What's wrong with this code?
Could it be that you are not using the same variable name? In the if statement
you are using $row['EndDate'] and when attempting to print you are using
$row['enddate']. I think you need to be consistent about which capitalization
you use (and make sure it matches what is in the db).

Re: [PHP] What's wrong with this code?
So your code looks like this?
while($row = mysql_fetch_array($result3))
{
echo "";
echo "" . $row['name'] . "";
echo "" . $row['type'] . "";
echo "" . $row['startdate'] . "";
if (!empty($row['EndDate'])) { //This should probably be $row
['enddate']
echo "" . $row['enddate'] . "";
}
echo "" . $row['location'] . "";
echo "" . $row['summary'] . "";
echo "" . $row['description'] . "";
echo "";
}
Not to mention, you have a $row['EndDate'] and a $row['enddate'].
Probably need to choose one or the other.
HTH,
Karl

Could the exit() be terminating it? Do you need this exit() as the
else for that if statement? Try deleting just the else {}.

It's one of the bizarre security loopholes in Linux. If you have write permissions to a directory but not a file within it, you can still delete the file. I believe you can change this behaviour with filesystem security mods, but I've not tried that. Thanks, Ash http://www.ashleysheridan.co.uk

[PHP] unlink()?
Hi gang: Never-mind. I didn't change the parent directory permissions to unlink the file -- duh! Cheers, tedd --- I asked: Hi gang: I use unlink() to delete files on my server by using the statement: unlink($filename); where $filename is the physical path to the file plus file name, such as: $filename = '/var/www/vhosts/domain.com/httpdocs/a-dir/a-text.txt'; Now, I can read, write, and even create the file -- so I have the path and permissions correct. But if I unlink() the file and then examine the contents of the parent directory afterwards, I find the file remains -- what's up with that? This reminds me of the process of deleting files on your local hard disk, which basically sets the disk-space allocated to the file as "available for writing" without actually deleting the file.

Re: [PHP] CakePHP, alternatives?
One other thing I will add: Don't just learn PHP. Learn Javascript as well. Don't treat it as PHP without dollar signs, but learn Javascript as Javascript, and PHP as PHP. Then after you've gotten some time with those, take some time to learn, or at least learn about even if you never work with it, Erlang. Or Haskel. Or some other stricter, purely functional language. Something that works totally differently than PHP. Even if you don't ever use it, the perspective you gain from approaching a problem from a different angle will help you learn about the strengths and weaknesses of different languages, different ways of thinking, different ways of leveraging your tools well, etc. The 6 hours or so I spent reading about Erlang and purely functional languages helped my PHP skills considerably, even though I never wrote a single line of Erlang. (I was already very solid in PHP at the time, but it made me even better.) --Larry Garfield On Saturday 05 June 2010 12:51:47 am Shreyas wrote: > @ All - Points duly noted.
