Any recommendations would be appreciated FCKEditor was a pretty simple to integrate into a CMS. I had to edit some of the code to segregate image uploads on an article by article basis with permissions blocking, but all in all a decent experience. They have good separation of the configuration system such that you can override configuration settings in several different ways to suit your needs. The only part that was a bit questionable was configuring their PHP scripts that hook into their dialogs (such as the filemanager).

[PHP] HOW update time and date-fields to mysql....
Hi there guys!
I have used a date-field and a time-field in a mysql-database.
How should I update these fields through php?
This is my code now (it works fine locally with data on a win-machine, but
not on Linux at my webhotel - Time doesn't work at all)
function safeQuote($value)
{
// Stripslashes
if (get_magic_quotes_gpc()) {
$value = stripslashes($value);
}
// Quote if not integer
if (!is_numeric($value)) {
$value = "'" . mysql_real_escape_string($value) . "'";
}
return $value;
}
$sql = "UPDATE tbforum SET";
$sql .= " question=" . safeQuote($frmQuestion);
$sql .= ", insertDate='" . $dat . "'";
$sql .= ", insertTime='" . time() . "'";
$sql .= " WHERE IDForum=" . safeQuote($idForum);
$querys = mysql_query($sql);

Have you tried printing out $sql? Does it contain what you expected? Does the mysql_query() succeed? what does mysql_error() tell you about what went wrong? I'd be absolutely amazed if time() really doesn't work. I'm *guessing* that as you're running stripslashes() on these variables, you're running your local machine with register_globals set on, but the Linux machine has register_globals turned off. -robin

MySQL will then add the date and time according to whatever those values are on your db machine. Cheers Matt

Thanx for your input about date & time...

function currenttime() {
-snip- lot's of code.
Hi Gustav:
Not meaning to embarrass, but your code could be shortened
considerably by using date(), like so:
Your lengthy -- function currenttime()
can be replaced simply with:
echo("Date: " . date('Y\-\ m\-\ d') . "" );
and your -- function currentdate()
can be replaced with:
echo("Time: " . date('h\:\ i\:\ s') . "" );
If you don't like the spaces in the output, then strip them out, like so:
$date = date('Y\-\ m\-\ d');
$date = str_replace(" ", "", $date);
echo("Date: " . $date. "" );
and
$date = date('h\:\ i\:\ s') ;
$date = str_replace(" ", "", $date);
echo("Time: " . $date. "" );
You can find more code examples at:

something like
$domain = preg_replace('{^([a-z]+://[^/]+).*$}X', '%1', $uri);
We are two different people !? Not sure how that's difficult.
Did I say difficult? What I meant is that seing a question from Chris,
immediately followed by a message from Chris leds to think it's an
"extension" of the question (maybe something he forgot, or something
new), but it wasn't, it was an answer from (a different) Chris, hence a
little akward.
--I hope this makes things clear for you.
I don't know why you'd use a regular expression when you can use a
function instead (easier to maintain, it'll be faster, you won't make a
mistake)...
What I sent was a way to get what he wants in 1 function call. You
should understand that preg_* family functions are just like str_*
family functions, they work with strings, it's as simple as that -and
yes, they're functions too.
Now, probably parse_url() relies in preg_* or ereg_* functions -that
wouldn't be rare-, so I don't think parse_url() would be faster than
preg_replace(), and even if it is the difference would be meaningless;
and neither I see how writing more lines would be faster. I also would
like to know how the use of parse_url() would guarantee that he won't
make a mistake.
Man, I can only conclude you've satanized preg_* functions because of a
lack of knowledge, and I suggest you to investigate more about them,
they're quite useful the same for easy and complex tasks. Someone said
once that you don't know the power of regexp until you know them, and
that's definetely true.
But of course there is always more than one way to solve a problem.
Agreed, so Chris may consider whatever he likes the most. If he, like
you, thinks that regular expressions are too complex and don't like the
idea of knowing them, then he will most likely choose parse_url() -which
is just fine.

So you know $res *isn't* an array, which is why you're getting the warning that "The argument should be an array". So you need to find out what *is* in $res, which is why I suggested the print_r(). Now do a var_dump($res) and see what *is* in $res. Then you'll have to work out *why* it's not an array - and the answer to that is somewhere in those 300 lines of code you can't post. The few lines at the end of the loop seem to be treating $res as an array. But as it's *not* an array, either those lines aren't being executed or you've initialised $res to something silly beforehand, like a string. -robin
[PHP] Session problem when upgrading from 4 to 5.
Hi, Unfortunately it is not possible (for me) to initialise the 'session.save_path' directive in PHP 5. Up to version 4.3.5. there was no problem and the directive was set to '/tmp'. After upgrading to 5.0.2. and later to 5.1.2. I did not succeed in initialising the directive. /usr/local/lib/php/php.ini: session.save_path = "/tmp" Configuration history related to the 'session.save_path' directive: PHP Version 4.0.0/tmpgood PHP Version 4.3.5/tmpgood PHP Version 5.0.2no valuewrong PHP Version 5.1.2no valuewrong Checked with phpinfo(). I have checked the NEWS file and found two remarks concerning the save_path directive: - Fixed bug #33072 (Add a safemode/open_basedir check for runtime "session.save_path" change using session_save_path() function). (Rasmus) - Fixed bug #33520 (crash if safe_mode is on and session.save_path is changed). (Dmitry) So my question is: Is it possible to define the directive 'session.save_path' in PHP 5 in the php.ini file? Matthijs Dijkstra

It is and the key word here is "Follow" as in resolve the real file location before parsing.
This is clearly an Apache problem. I have asked this question on a few Apache forums and lists now and have not had any response.
Is there any way to make Apache parse the files where it finds them and not go looking for the real file?

I am trying to stop PHP from resolving symlinks. I have a PHP CMS that I use

the sites to run the exact same PHP CMS code but use their unique
directories to host the different config files. The problem is that the PHP
scripts are running from the directory that the links point to and not the
directory where the site is. The big problem with that is the CMS tries to
read a configuration file that is in a relative location to the PHP script
like ../config.php.

Bash is doing what I need. It sees the current directory as the full path of
the symlink.
The admin.php at this point only has system("pwd"); in it and it prints out
/usr/local/cms/admin as the directory it is in, not what I want. It will
never see the ../config.php file.
I tried doing this
chdir ($_SERVER[DOCUMENT_ROOT]."/".$_SERVER[REQUEST_URI]);
but it still resolves the link and does not accept the path that I
constructed.
How can I make PHP use the symlink and stop trying to resolve the original
files?

I have implemented file uploads to my server. At the end of upload, file is beeing moved from /tmp to permanent directory. However, whenever this happens, CPU goes berzerk and waits for disk to finish moving file. As allowed files may be up to 100 MB per file, having more then 3 users makes complete server freeze. Meantime, server load reaches skyhigh 40+. After file is moved, server resumes normal operation, however while moving file server is completely not responding. I'm just taking a wild guess at this moment, but usually is a sign when disk access is an issue and tends to be because it is rather full excpecially with larger files. Some questions that i that I would first look at: - how much space is on /tmp or the drive you are moving it to - is /tmp on the same drive as where ever you are moving it to. - if it is the same drive, the move should be quick - test a move directly on the filesystyem and see how long it takes Just in case you arn't familiar with disk usage do a: du -h and observe the output. Is there a work around? I am not so good with linux (yet ^^), so I do not know if there is place for improvement on OS itself. I asked this question on Debian forum, but am trying here as well. If someone has same problem and prefferably solution, or even sugestions - all is welcome! :) Although of what I mentioned really shouldn't explain your 40+ load unless you are under requests and you are very close to 100% on one of those disk partitions from 'du'. 2 x 80 GB IDE HDD Since you have 2 disks i would suggest putting all your logging information on one disk or the other and reserver the other disk for accessing pages or uploads. But then again it really doesn't explain the 40+ server load, you may have other issues at hand.

[PHP] Array sort question
Hi,
How can I sort a 2 dimensional array by number of
elements?
Ex:
rgArray[0] = ("1","2");
rgArray[1] = ("1");
rgArray[2] = ("1","2","3","4");
rgArray[3] = ("1","2","3");
Now I would like to sort it so I can loop through
them from least elements to most (or vice versa):
rgArray[1] (now
rgArray[0]) 1
rgArray[0] (now
rgArray[1]) 1,2
rgArray[3] (now
rgArray[2]) 1,2,3
rgArray[2] (now
rgArray[3]) 1,2,3,4
Thanks.

and your -- function currentdate()

If you don't like the spaces in the output, then strip them out, like so:

$date = str_replace(" ", "", $date);

That's not entirely fair. I would have said his usort() suggestion was
a better pointer than a link to count() - which gives no hint as to
how to sort the list, which is after all what the OP's trying to do.
ObSuggestion:
function byLength($a, $b)
{
return sizeof($a) - sizeof($b);
}
usort($rgArray, 'byLength');

The docs for date() (http://www.php.net/date) show that there are a
number of different options for the first parameter. If you check out
the table on that page, you'll find:
>> H | 24-hour format of an hour with leading zeros | 00 through 23

[PHP] Basic PDO Questions
I have a three quick PDO questions. 1) If a PDOStatement is created within a function or method, is it's server result set connection is automatically freed up when the function returns (I assume so, but want to make sure)? 2) Does setting a PDOStatement to null (PDOStatement = null) terminate the server result set connection (I assume so, but want to make sure)? 3) The documentation for PDO::quote encourages us to use prepared statements over the PDO::query() or PDO::exec() methods citing the economy and portability of prepared statements. For queries that will run only once, is there significantly more overhead using prepared statements rather than the PDO::query() or PDO::exec() methods? I know that that's kind of an unclear/subjective question, but I just don't know how to state it better.

Go in through ftp or ssh and fix the permissions.
If you only want to read the file, then it only needs to be 644.
If you need to write the file it will either need to be 646 or 664.
That's your only option apart from deleting the file (through ftp) and
recreating it through your php script ... or getting your host to change
to the CGI version of php which is most unlikely to happen.

print "There are currently no categories";
} else {
while($r = $mysql->fetchrow()) {
$cid[] = $r['cid'];
}
foreach($cid as $value) {
Try that as
foreach($cid as $cidpos => $value) {
Does $cid actually have all the values that it should?
echo sizeof($cid);
just before the foreach.

[PHP] Dynamic Form List - how to change values
I have a list from a MYSQL database that I am dumping to a screen. I'd like the user to be able to change the quantity on the form for any record on the screen, then post that information back so the user can review it, and I can then update the database. Simple checkout routine. Or so I thought. I have these fields displayed on the screen before the user changes the quantity: $imageqty = $row["cialbum"]."-".$row["ciset"]."-".$row["ciimage"]; $qty = $row["ciqty"]; print "name='$imageqty' size='5' value='$qty'>"; I've set the $imageqty variable to hold the initial value from the database. The initial screen works fine. However, when I reprocess the file, how can I retrieve the original value of the field that is named the same as $imageqty? The form outputs something like this: http://.../chkout.php?NATURE-1.jpg=6&continue=Continue+Checkout, which does show the $imageqty of "NATURE-1.jpg" value with the new qty of "6". How can I get the script to pull the value? $imageqty = $row["cialbum"]."-".$row["ciset"]."-".$row["ciimage"]; $newqty = $_GET["$imageqty"]; Retrieves nothing. Thanks for your help.

Correct. Assuming you dont return it or assign a function input
variable that is being passed by reference.

I assume you mean a variable that contains a PDOStatement:
$stmt = $dbh->prepare($sql);
$stmt = null;
Yes this is correct. The one thing to keep in mind though is the
above will be only true if you havn't assigned $stmt to another
variable:
$another_stmt = $stmt;
$stmt = null;
The result set connection will still exist, until all variables
referencing to the object are unset/null'd

The key points addressed in the docs with using prepare instead:
* portable
* immune to sql injection
* speed
As far as portable, as noted in the next paragraph, the ODBC driver
doesn't support the quote() method, so if you are crafting a sql
by hand (within your app) you will have to know what driver you are
dealing with.
Also, using just a prepare/execute method, it makes your code much
easier to allow for abstract database servers. This is why i like
pdo so much, it isn't an abstract layer but allows you to build a
common interface that can be abstracted.
The Immune to sql injection. This is rather straight forward, you
just set up your query with input variables and assign the
variables to the input variables:
$sql = "select * from some_table where userid = ? and name = ?";
$stmt = $dbh->prepare($sql);
$stmt->bindValue(1, $_GET['userid'], PDO::PARAM_INT)
$stmt->bindValue(2, $_GET['name'], PDO::PARAM_STR);
With the above code you dont have to worry about escaping data nor
how it is needed to quote the variable, it is handled by the
driver.
With speed, benchmarks will only show a difference if you have code
like:
$sql = "select * from some_table where id = ?";
$stmt = $dbh->prepare($sql);
foreach(array(1,2,3) as $id) {
$stmt->bindValue(1, $id, PDO::PARAM_INT);
$stmt->execute();
}
vs.
foreach(array(1,2,3) as $id) {
$sql = "select * from some_table where id = " . (int) $id;
$stmt = $dbh->query($sql);
}
The speed difference is with query() and the server has to parse
the query to make sure it is valid and then execute within each
iteration of the loop. With the prepare/execute method, the server
just parses the query once. I would assume stored procedures or
views benefit more with this method since they are a bit more
complicated to parse.
HTH,
Curt.
