Ethan - you are simply missing two dollar signs as pointed out. Once
you correct them, if there are any more errors you should then be
seeing
the message from mysqli_error.
And as for the advice to dump single quotes, I'd ignore it. The use of
double and single quotes is a very handy feature and makes for very
readable code. Escaping double quotes is such a royal pia and
makes for
more trouble deciphering code later on. The sample you provided
for us
is some of the best and most understandable code you've ever showed
us.
Also - Ethan - if you used an editor that was designed for php you
probably would have seen these missing $ signs since a good one would
highlight php syntax and the lack of the $ would have produced a
different color than you expected.
Jim -
I used Netbeans. All it said is "variable unused is scope", which is
a error that I often find does not mean anything. I am as pressurized
as you are. Any suggestions as to an editor?
Ethan
Did you mean to say "unused IN scope"? That would be telling you that
it is not yet defined and that could be a problem if you expect to be
already defined.
Several other posts here have listed their favorites. Notepad ++
seems to be a favorite. I use HTML-kit Tools as my developing
environment. Handles highlighting for php, html and js, as well as
project organization. Also includes an ftp engine to allow me to
modify, upload and then go test my code very quickly. (I don't run php
or apache locally.)
Jim -
Thanks.
unused IN scope - correct.
There are lots of editors mentioned in this email trail. I thank all
for the suggestions.
Netbeans, Aptana Studio, etc will all highlight code and show the errors
the code would generate in a browse. The problem here was two missing $
signs.
I'm probably wrong, but in some contexts; eg, sql query, $ signs are not
used. I tried and added the incorrect $ sign, and Netbeans did not
complain. If anyone knows of an editor that will able to spot this kind
of error, please inform the list.
Ethan
Wrong in one sense - all php vars must have a $ sign. When building a
query statemtent, if the editor doesn't tell you something (by not
colorizing it) Sql is going to tell you when you attempt to run it.
That's why one should ALWAYS include an error check after any operation.
BTW - this line
echo '$sql2';
isn't going to give you what you want.

If anyone knows of an editor that will able to spot this kind of error, please inform the list. You do need to take a little more care when using variables IN strings and watch that they are highlighted. As you say, the parsing is not actually wrong as it is valid 'text' and adding SQL parsers for every database is not really practical and probably would not fix the problem anyway? Personally I use Firebird, and have always built the SQL using parameters, so that the SQL is pure text, and values are passed in an array. This is something MySQL was a lot later in catching onto, but many of the simple security problems are totally eliminated using that approach. -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ethan - you are simply missing two dollar signs as pointed out. Once
you correct them, if there are any more errors you should then be seeing
the message from mysqli_error.
And as for the advice to dump single quotes, I'd ignore it. The use of
double and single quotes is a very handy feature and makes for very
readable code. Escaping double quotes is such a royal pia and makes for
more trouble deciphering code later on. The sample you provided for us
is some of the best and most understandable code you've ever showed us.
Also - Ethan - if you used an editor that was designed for php you
probably would have seen these missing $ signs since a good one would
highlight php syntax and the lack of the $ would have produced a
different color than you expected.

Dorschner"" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Good Morning, I've been searching and toying with this solution for some time but can't find that right answer. Looking for solutions/suggestions to the following: I created a program that will allow people to track sales and depending on what they've sold, they will either get a set bonus, or a bonus based on a percentage. I have no problem creating a drop down box for them to select from, and I could probably create a select button that would do the action, but I'd rather have it in one step. So what I'm trying to do is somehow when they select from the drop down (via a JavaScript onchange or something) I'd like it to pull data from the MySQL database. I'd like it to pull the amount and then each or per based on the ID of what they've selected from the drop down. If it was always based on each sale or based on a percentage, that would be easy as I could code that into the drop box, but I'd like to keep it based on the ID so that it can pull out of the database the name, and then when changed pull the info.

[PHP-DB] Re: MySQL query problems...
The error message and when I have problems I find it's very helpful to print the actual value of the $query variable. In your case it looks like AND acct_db.key1 LIKE \"%\".AllMid_Data.CPU_Hostname is adding AND acct_db.key1 LIKE "%".AllMid_Data.CPU_Hostname and you can't join two strings in SQL with a '.' like you can in PHP you should use a + for the two strings.

[PHP-DB] Re: MYSQL query help
There are several ways to get around the lack of subselect support in mysql. For your situation you can simply use: SELECT * FROM lib_asset_tbl, lib_copy_tbl WHERE lib_asset_tbl.material_id <> '' AND lib_asset_tbl.asset_id = lib_copy_tbl.asset_id of course, this will return a row for every instance of a many to many relationship, so you may want to use a GROUP BY clause to reduce the number of rows in the result.
