Hello,
I am running into an issue where when a user inputs an apostrophie '
into the textarea section of my form, it will generate an error in the SQL
statement.
I have narrowed down the issue to this snippet of code:
$insertQuery = INSERT INTO changeLog(vendorNumber, newVendorNumber,
oldName, newName, changedBy, dateChanged, comments)
VALUES('$vendorNumber','$newVendorNumber','$oldName','$newName','$changedBy'
,'$dateChanged','$comments');
The thing that is causing this issue is the use of apostrophies to
designate my variables in the SQL query. How do I rewrite this to avoid
this issue?
Thanks,

Re: [PHP] AOL problem with remote IP address
AOL uses load balancing proxy servers which means every new page load could
come from a different IP address.

I haven't heard about address' changing midway through a session (ie,
without reconnecting), but it's worth pointing out that there will be a
few
other reasons why this isn't a good idea:
1. if they have to reconnect, they're near guaranteed to have a new IP
2. with most big ISPs, all users may *appear* to have the same IP... so
any
of them could hijack the session?
The only way to test if IPs ARE changing is to get/borrow an AOL account,
and create a page which you can refresh 30 times over an hour, looking at
the IP address' each time. That should confirm/deny the problem.
But I wouldn't be relying on a remote IP for anything... they're too
unreliable.

Quite an interesting quandry I have.
What I have is this:
Table schooltypes:
(typeid is a unique# iding the type, schooltypes is the type of school,
say
Elementary School or High School)
| typeid | schooltypes |
Table schools:
(typeid is the type the school falls under, schoolid is the unique# iding
the school, schoolname is the general name like Park Shore High School)
| typeid | schoolid | schoolname |
Table teachers:
(tuserid is their unique id, salutation is the Mr/Mrs/Miss/Ms/Dr, last
name
is well, duh :))
| tuserid | salutation | last name |
Table teachers_schools:
(tuserid is the teacher's id, next to the school they are assigned to.
Note
the possiblity for a teacher assigned to more than one school (hello,
cutbacks and skeleton budgets)).
| tuserid | schoolid |
What I need to be able to do is list all this information as such:
School type:
+ School 1
- Teacher and their Teacher ID
- Teacher and their Teacher ID
+ School 2
- Teacher and their Teacher ID
- Teacher and their Teacher ID
- Teacher and their Teacher ID
+ School 3
- Teacher and their Teacher ID
- Teacher and their Teacher ID
Another School Type:
+ School 5
- Teacher and their Teacher ID
- Teacher and their Teacher ID
+ School 7
- Teacher and their Teacher ID
- Teacher and their Teacher ID
Currently, I AM able to list the school type and the school correctly.
However, when I come to listing the teachers in the school, every teacher
is
listed under every school, some more than one time.
Any ideas/code snips on how to do this?
In what direction should be I solving this?
Going from type-school-teachers assigned-teacher info?
Or teachers assigned-teacher info-schools-type?
Right now I am doing the first, sorta.

Hello!
How can I make a variable, which name I give to a function, global in
this function?
I want to make something like:
function MyFunc($sVarName)
{GLOBAL [$sVarName]_error, $sVarName_ok;
}
So if $sVarName = sHello, I want to access $sHello_error and
$sHello_ok in this function.
Any idea how I can make this variable gloabl and whats the easyst way to
access this var then?

Re: [PHP] Re: Making variable global / accessing variable
But how would you use this to create new global variables with $td as the
prefix?
$td = foo;
then we want new global variables
$foo_error and $foo_ok created.
