Re: [PHP-DB] Define constants: awkward usage?

Hi all,
I got this sets(20) of defined constants which using them as keys to an
array
eg
define(FNAME, fname);
farray = array( FNAME = hello ,...);
my question is how do I insert that directly into a javascript(to do
some client validation)
I need this:
var fname = document.addrform.fname.value
var fname = document.addrform.{FName}.value//don't work
var fname = document.addrform.{'FName'}.value//don't work
var fname = document.addrform.[FName].value//don't work
I know this work, but messey
$tmp = FNAME;
var fname = document.addrform.{$tmp}.value
you could try sprintf()/printf():
$output = sprintf('var fname = document.addrform.%s.value', FNAME );
or
printf('var fname = document.addrform.%s.value', FNAME );
I'am finding the use of define constants rather awkward. does anyone
make much use of them?
yes. :-) for...
session varnames
post/get varnames
bitwise flags
er...?
Thanks
Tony

Re: [PHP-DB] Define()
The reason it doesn't work may go beyond PHP. You are trying to make an HREF point to an exact location on your hard drive. When the user of your web page clicks the link, they do not have that location on their system so it will fail. Always use relative locations for links. Then once you get that ironed out, skip the defines, just use the variables. Change the code to be: $doc_dir = /store/; $image_dir = /images/; $control_dir = /control/; ?php echo $control_dir ?verify_login.php a href=?php echo $doc_dir ?click here/a and don't forget the 'php' after the ?

RE: [PHP-DB] Define()
Jim, Thanks for reply. I haven't moved this into production yet, the d:/is/ was just for testing as well as because when I use /client_name, the links do not work. I will to use the variable names instead of the define and see where this gets me. Just to note, I tried define(IMG_HOME_ROOT, /client_name/web/images/); and it didn't work What would be the difference between using that and $img_dir = /client_name/web/images/; --- Jonathan -Original Message- From: Jim Hunter [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 12, 2003 12:58 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: [PHP-DB] Define() The reason it doesn't work may go beyond PHP.

RE: [PHP-DB] Define()
For starters, and in general, does anyone know why a view source would not work in IE 6? This hasn't worked for weeks, so I usually have to use Mozilla to view the source. Anyway, Jim, this is my basic page setup. ?php include_once(../common/store_config.php); include_once(HOME_DOC_ROOT.common/header.php); ? This is where my HTML codes goes. So for example, a link to another page would look like this a href=? echo DOC_HOME_ROOT ?stuff/index.phplink/a a form would look like this form action=? echo CTL_HOME_ROOT ? method=POST /form ?php include_once(HOME_DOC_ROOT.common/footer.php); ? Note: within store_config.php I am declaring the constants along with including some other files which I reference. For example, there is a file called system_messages.php from which I pull system messages like Item was added to your cart, Please enter in all the required information, etc. Currently I have the constant IMG_HOME_PATH set to /killerspin/web/images/ and everything is fine. For DOC_HOME_PATH I have /killerspin/web/store/ but I get all kinds of errors like could not create stream. Specifically Here is the code. ?php include_once(common/store_config.php); include_once(DOC_HOME_PATH.common/header.php); ? p class=contentThis is the index page./p ?php include_once(DOC_HOME_PATH.common/footer.php); ? and here is the output Warning: main(/killerspin/web/store/common/header.php) [function.main http://www.php.net/function.main ]: failed to create stream: No such file or directory in D:\is\clients\killerspin\web\store\index.php on line 3 So I replace the code with this, include_once(/killerspin/web/store/common/header.php); Same thing happens, but if I put include_once(http://localhost/killerspin/web/store/common/header.php;); then it's fine BUT the images don't show and I haven't changed a thing on the for IMG_HOME_PATH!!

Re: [PHP-DB] define variable by querying MySQL
Hi,
I'm not sure what were you trying to do but there are some very obvious
errors
1. You cannot embed one php openning tag (?) in another
2. mysql_numrows() is not a valid mysql function - may be you were trying to
use mysql_num_rows()
If you are trying to put all fields my_name into the $WELCOME variable (I
can't think of a reason to do this) and then echo it may be you could use
this code
#start code
?
$link = mysql_connect(localhost,username,password) or die (Could not
connect to MySQL!);
mysql_select_db(database,$link);
$result = mysql_query(select * from table_name);
while ($row=mysql_fetch_array($result)){
$WELCOME.=$row[my_name];
}
echo $WELCOME;
?
#end code

Subject: [PHP-DB] define variable by querying MySQL
hello list. i have a problem that is relatively simple, but I can't seem to
figure it out.
is there any way to define a variable by querying a MySQL database?
here's an example of code I tried using:
?
$WELCOME =
echo ?php
$link = mysql_connect(localhost,username,password);
if(!$link) die (Could not connect to MySQL!);
mysql_select_db(database,$link);
$result = mysql_query(select * from table_name);
$num=mysql_numrows($result);
for($x=0;$x$num;$x++) {
$row=mysql_fetch_object($result);
print $row-my_name;
}
mysql_close($link);
?
;
;
?
? echo($WELCOME); ?
it kept coming up with the following :
Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or
`T_NUM_STRING' in c:\apache group\apache\htdocs\page.php on line 5
i can't figure out what to do, so if anyone can assist me, i'd be greatful.
I have a feeling it's something with some quotes but i can't figure out
which ones.
Thanks a lot,
Matt Nigh
