[PHP-DB] Determining if checkbox is selected in PHP
I'm storing the values from a groups of checkboxes in an array keyword[], but $_POST['keyword'] is undefined if none of the checkboxes is checked. I tried using in_array() with $_POST to determine if any of the group of 'keyword' checkboxes is checked, but can't get it to work; does anyone have any suggestions? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP-DB] Determining if checkbox is selected in PHP
you could first check for isset($_POST['keyword']) and then if that passes check what keywords you have. or you could write an additional html tag to the page like. input type=hidden name=keyword[] value=NA. This would force the $_POST['keyword'] array to exist and then you'd have to strip that from your array when processing it hth Jeff Keith Wilkinson [EMAIL PROTECTED]To: [EMAIL PROTECTED] be.ne.jpcc: Subject: [PHP-DB] Determining if checkbox is selected in PHP 09/09/2003 08:09 AM I'm storing the values from a groups of checkboxes in an array keyword[], but $_POST['keyword'] is undefined if none of the checkboxes is checked.

Re: [PHP-DB] Determining if checkbox is selected in PHP
I'm storing the values from a groups of checkboxes
in an array keyword[], but $_POST['keyword'] is
undefined if none of the checkboxes is checked.
The fact that it is undefined if none of the checkboxes
are checked is expected behavior. Just do:
if( isset( $_POST['keyword'] ) {
}
to determine if you need to do any further processing.
I tried using in_array() with $_POST to determine
if any of the group of 'keyword' checkboxes is checked,
but can't get it to work; does anyone have any
suggestions?
if( isset( $_POST['keyword'] ) {
foreach( $_POST['keyword'] as $checkboxValue ) {
echo 'Checkbox ' . $checkboxValue . ' was checkedbr';
}
}

[PHP-DB] Creating an autonumber setup
Hi, Could someone explain to me how this could be done? I have seen something similar using Access on a local machine and would like to know if it is posible to do it in PHP and Mysql In a project management web based applicaton using PHP and Mysql I would need to allow the user to create Quote Project Customer Supplier Invoice Each time one of the above will be created it needs to be assigned an autonumber. So If 3 quotes were created today each quote would receive an autonumber, maybe something like the fllowing: yy/MM/dd-01 yy/MM/dd-02 yy/MM/dd-03 Creating the autonumber isn't the problem if I want to have a set way of numbering, however, is it possible for me to allow the user to enter a setup page or something and define the way the autonumbers will look like and be created for quotes, projects, customers, suppliers or invoice. let's say I have five Project Managers each working with a seperate version of the app. The app currently sets each new project created with a default autonumber (let's say yy/MM/dd-01, -02, 03 and so on), however, each Project Manager wants their database to number new projects differently: PM1 = yy/MM/dd-a PM2 = dd/MM/yy-01 PM3= YY- (Number being the amount of projects this year) PM4 = PROJ- (Number being the amount of projects ever) PM5 = P-yyMMdd1 Instead of me creating a different application for each project manager can I allow them to setup their own number system in a set up page? Many thanks for any ideas Richi

Many thanks for any ideas Richi I'd suggest not mixing display with data storage. That is, use MySQL's autoincrement function to give each row in the table a unique ID. Then have a prefix/suffix combo for each proect manager. So if they want their numbering to be Fred's project #234 for this year, the prefix could be Fred's project # and the suffix would be for this year. You could have variables in there as well, and you can do number- text translation if necessary (a,b,c rather than 1,2,3). But do the translation in the application (or your query), not within the database. That way if a project manager takes over another one's work, you don't need to change the data, just the function that handles the numbering schemes. = Mark Weinstock [EMAIL PROTECTED] *** You can't demand something as a right unless you are willing to fight to death to defend everyone else's right to the same thing. *** __ Do you Yahoo!?

Re: [PHP-DB] foreach() db brainiacs please help?
couldn't this be accomplished with a Left Join? Depending on how your
tables are arranged you should be able to get all (sub)sub-names out and in
the same result set using the top_name with a Left Join. any key that
relates to the parent key would be returned.
it looks like you have them all in the same table thoughwhich may
furuther complicate things, if so, how is the relatoinship maintained in
the table(s)?

Re: [PHP-DB] RH 8.0 Mysql help
One comand and you are done: apt-get install mysql-server httpd php php-mysql Don't have apt for RedHat? Download this: http://ftp.freshrpms.net/pub/freshrpms/redhat/8.0/apt/apt-0.5.5cnc6-fr0.rh80.1.i386.rpm and run 'rpm -i' on it. There's no better way to install software than apt. Prefer a graphical installer? Do this: apt-get install synaptic Good luck! --Dave Robin Kopetzky wrote: Would some kind soul who has installed MySql on a RH8.0 box please email me (off list) and help me get this running??
