Your quotes are wrong and you shouldn't use NOW like that: $query_rsENews = "SELECT * FROM NewsArchive WHERE YEAR(datePublished) = YEAR(NOW()) AND MONTH(datePublished) = MONTH(NOW()) ORDER BY sortBy DESC"; Should be a lot closer to what you want. -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html

You're mixing php and mysql, you've changed from using php's date() function to mysql's functions. Not to through a whole new twist into all your problems but your query probably should be written differently: $query_rsENews = 'SELECT * FROM NewsArchive WHERE datePublished >= DATE_FORMAT(NOW(), "%Y-%m-01") ORDER BY sortBy DESC'; And add an index on the datePublished column. You'll notice a considerable speed difference. Curt -- "I used to think I was indecisive, but now I'm not so sure."

this is supposed to return only the records that have the current month and year in the datePublished record.
got this error: Fatal error: Call to undefined function: year()
You sure you did not mean $dataPublished?
I think datePublished is his columnName?
But also:
Assuming mySQL (I can't find your original post?):
+++This is all wrong:
mysql> SELECT YEAR('NOW'());
ERROR 1064: You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '())' at line 1
+++This is even worse, really: mysql> SELECT YEAR('NOW()'); +---------------+ | YEAR('NOW()') | +---------------+ | NULL | +---------------+ 1 row in set (0.00 sec)
+++This is what you want: mysql> SELECT YEAR(NOW()); +-------------+ | YEAR(NOW()) | +-------------+ | 2004 | +-------------+ 1 row in set (0.00 sec)
So I'd guess at your syntax being: $query_rsENews = <<<_SQL SELECT * FROM NewsArchive WHERE YEAR(datePublished) = YEAR(NOW()) AND MONTH(datePublished) = MONTH(NOW()) ORDER BY sortBy DESC _SQL;

--- Begin Message ---Curt, thanks, your code works perfectly. Can I ask you two questions? 1. I am not sure what you mean by adding an index. I looked in the mySQL help files and from what I can figure, I have already done that... 2. Now that the code actually works, we have come up with an issue. When the current e-news newsletter (the table holds the current AND the archive enews newsletters) doesn't get updated until a few days into the month, then the page will be blank until she puts articles in for that month......is there a way to just say "show me the articles with the most current dates" ? thanks "Curt Zirzow" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] > * Thus wrote msa ([EMAIL PROTECTED]): > > > $query_rsENews = 'SELECT * FROM NewsArchive > WHERE datePublished >= DATE_FORMAT(NOW(), "%Y-%m-01") > ORDER BY sortBy DESC'; > > And add an index on the datePublished column.

If that is the case, you may be able to set up a key for the webserver user to access the remote account. An alternative would be to use the -i option to scp to specify the key file (man ssh). In that case, it's likely that the webserver user would need permissions to be able to read that key file. Either solution could be a security issue, if you are on a shared server, as it might allow other users to use that same key to access the remote server as well.

Uh, I was wrong...
Foreach evaluates only once at initialisation... You can even unset the array once into the loop and it still works perfectly well (not that I recommend this as good practice or whatever, just did some checking to be sure :)

That will work because foreach iterates over a copy of the array. I often do things like:
foreach($arr as $key => $val) { if(some condition) { unset($arr[$key]); } }
Just one other thought. For those of you using PHP5, you can change the actual values in an array by using a reference.
foreach ($arr as $key => &$val) { if ($condition) { $val = $newval; } }
Putting the & in front of the $val tells PHP to use references, which would change the values of the original array. Just another way to skin a cat :)

I haven't done it, but if you have Windows + Word on the server then you can take advantage of the native Word API using COM. Pseudocode would be something like this:
1. Handle uploading the file to a temporary directory 2. Create a COM object for Word 3. Use this COM object load the temporary file 4. Use the adobe/pdf distiller to convert the file to a pdf file.
Please, if you do this let us know how it went so others can benefit.

I don't think you need steps 2 and 3. Just upload the file, then have a cron job (or Windows "at" job) distill the file. However, there might be some licensing issues -- you should probably look at the Adobe Distiller license.
Adobe sells a Distiller server for 100 users for $5000, unlimited users for (cough) $15,000. See their website for details.

Hi all!
Let's say I have a PHP script that needs the user to input some data during its execution. At the point the data is needed the browser could be redirected to a new page with a form where the user could enter the data. But thus is necessary to save the script state in order to continue its execution once it gets the data.
It would be preferable to mantein the execution of the script waiting for the data (in a while loop or sth similar). But, how can then the
Why keep the script running in the background? You'd just waste server time waiting for a response. What if you never received the response?
user introduce such data? With frames? One frame could execute the script, maybe outputting some information about execution and the other frame could ask for the data when needed. I think this could be done
That's reasonable You could seperate the "data" form into a seperate form and pass information if you really wanted to. Using a login for users and then passing information via $_SESSION variables would be a good way to do this. Or if you really really refuse to use sessions you could use serialize() and unserialize().
http://www.php.net/serialize http://www.php.net/unserialize
inserting JavaScript tags in the output of the script and flushing them to the browser in order to redirect the other frame to a form page. Is this valid? Do all browsers execute JavaScript commands before the page is completely charged?
No. PHP runs server side and can't wait on client side JavaScript execution. Besides, some people don't use JavaScript at all so if this is something that is required input then some people just won't see it.
Please, tell me if anyone has solved this problem in any other (maybe better) way.
Use a login mechanism, go to the data form, save the data into the session, and then retreive the session data on the other page.
Thanks, Regards, Germán

Any ideas? Why not just strip out the braces and explode on commas? That'll be lighter than regexps any day. If the input is guaranteed to be formatted the way you describe, you could do something like: $out = explode(",", substr($in, 1, strlen($in)-2)); -- Paul Chvostek <[EMAIL PROTECTED]> it.canada http://www.it.ca/ Free PHP web hosting! http://www.it.ca/web/

I feel very lost. as I experienced some minutes ago, the package "config" has some problems with xml-parsing. I don't know where is the problem exactly, but it is not compatible.

I never bother with getting the initial record count. Unless you want to display the total number of available pages, of course (in the vein of Google search result set). If all you need is to include "Previous" and "Next" buttons in the right places, you could simply go with: $length=40; // or whatever if ($_GET['offset']) $offset=$_GET['offset']); else $offset=0; // do the query $q="SELECT colums FROM table WHERE yadda LIMIT $offset," . 1+$length; $r=mysql_query($q); // make Prev/Next links as required if ($offset > 0) $prev="<a href='?offset=" . $offset-$length . "'>"; else $prev=""; if (mysql_num_rows($r) > $length) $next="<a href='?offset=" . $offset+$length . "'>"; else $next=""; // show the head print " <td align=left>$prev</td>\n"; print " <td align=left>$next</td>\n"; print "</tr><tr>\n"; // show the page for ($i=0; $i<$length; $i++) { $row=mysql_fetch_array($r); print $row['blah']; // wrapped in stuff, of course } The idea here is that we always try to SELECT one more entry than we can display on the page. If mysql_num_rows() sees that many rows, then there's a page after the current one. And of course, if $offset is > 0 then there's a page before the current one. I find that this method simplifies my code. I don't need to store the result of a COUNT() in a session variable, so the "count" remains valid even if the number of records changes while someone's browsing. Note that this is not safe code as is. :) At the very least, you should format-check $_GET['offset'] before using it for anything. p -- Paul Chvostek <[EMAIL PROTECTED]> it.canada http://www.it.ca/ Free PHP web hosting! http://www.it.ca/web/

You could perform the full (without LIMIT) query once, Cache the results array (using PEAR Cache) and move back-and-forth through this Cached array. Depending on the size of your resultset and the srength of your MySQL Server, this may or may not provide a mild performance boost.

--- Begin Message ---Hi, i'm designing a web application and i want to protect my web page from printing and if possible want to protect source code too. Do you know any solution that can help me. I've find an application named HTML guard but it only work for static html pages. I need more a class or function to prevent for printing. Thanks for your help, Marc

I need more a class or > function to prevent for printing. Disclaimer:: To my knowledge! :) The only thing off hand that I can think of that would prevent printing is a PDF file during setup. Your comparing apples to oranges here. PHP is server side, printing takes place on the client's machine. So they do have control over printing. You could check with Javascript folks, not sure if there is anything there that would allow for printing to be disabled as your normal browser's hotkeys such as CTRL+P will allow for printing even if you took away all other menus and drop downs. One thing you can do to limit the viewablilty of the source code is to place your website in Frames (This is optionally the last resort, as frames [in my own opinion] suck). And then using a "no right click" javascript application. Otherwise aftermarket encryption tools could help you here. But again, PHP isn't the answer for either of these. HTH, Wolf :)

--- Begin Message ---Hi,
I have a little problem with a script I am trying to make.
The main problem is that when I draw something on a translucent png created with gd, it will still take the color which was set as transparent color.
For a demo look at
http://www.cranberries-fan.com/images/transparent/test.php
The backgroundcolor is set to black so in the black box it seems to be ok, but in the yellow box you can see that the transparentcolor is blended over black :-( while the empty spaces around the circle is actually translucent.
Am I doing something wrong? I read something on the net about the bundled gd having a bug compared to this issue, so I installed php 4.3.6 this morning so that the GD lib would have version 2.0.22
GD Support enabled GD Version bundled (2.0.22 compatible) FreeType Support enabled FreeType Linkage with freetype T1Lib Support enabled GIF Read Support enabled JPG Support enabled PNG Support enabled WBMP Support enabled XBM Support enabled
look for the script at http://www.cranberries-fan.com/images/transparent/genimage.phps
What am I doing wrong or what is the GD lib doing wrong?

--- Begin Message ---I'm working on a project that collects data from different mysql servers, combines the data and then displays it. My problem right now is the collection part. I have two ideas: 1st, write a php script that is placed on the webserver where the database is. Every time my webpage is opened, it contacts each webserver and retrieves the info from the script. --> for this I thought if I could do a db query and export the data to a file then just upload the file to my server. Then I would have a script import the data Or, have the script get the info, then contact my mysql database and import the data that way, but how does it get from one connection to an other? 2nd, write a script that connects to the database each time my webpage is called. which one is best? How would I get the data so that it can be imported into my database? How would I transmit the data efficiently after I get it?(there can be hundreds of records on any given server). For those of you who are interested, what I'm trying to do is provide a centeral location for stats to be displayed for an online game called Delta Force. Any ideas? Thanks, Seth
