[PHP-DB] foreign key
Okay. I am pretty new to mysql so this may seem like a ridiculous question to some people. I am trying to use a LEFT JOIN query, but the results I am finding unusual. For every record occurrence there is for the query, the results are duplicated by that amount. So if there are 3 records from the query results, then the output is 3 times what I expect.. if that makes sense. From what I have researched so far. I believe I may need to add a foreign key to build the relations between the two tables. Based on the query can any tell me the correct way of adding the foreign key if ,in fact, that is what I need? I can provide table structures and information if necessary. The query is: $posts_sql = SELECT store_subject, store_comments, store_date, store_tptest, store_by, users.user_id, users.user_name, users.first_name, users.last_name FROM stores LEFT JOIN users ON stores.store_by = users.user_id WHERE stores.store_subject = ' . mysql_real_escape_string($_GET['id']).' ORDER BY stores.store_date DESC ; The query dump is: SELECT store_subject, store_comments, store_date, store_tptest, store_by, users.user_id, users.user_name, users.first_name, users.last_name FROM stores LEFT JOIN users ON stores.store_by = users.user_id WHERE stores.store_subject = 'Noland Park Plaza 3509 S.

Re: [PHP-DB] Re: radio form submission
Thanks everyone.
If there is no purpose, I would make the values of the inputs the values you
want to store in your database.
Muuch easier..
So I am trying to keep this simple and just assign the value with the
radio button and then insert it into mysql database, but with the
following code I am getting the mysql error: Unknown column '250kbps'

I think it has to do with the value being a string, but I haven't been
able to figure out the fix.

[PHP-DB] mysql_query
Hello all,
Not sure what I am doing wrong.
I have a simple form that populate the variables in a mysql query. I
know the selected values are making it to the form porcessing script
because I can echo them on the processing script as indicated below.
You Selected Cell_Sect = 1_1
You Selected Date = 03/10/11 18:15
You Selected Market = MCI
For some reason the above is all I am getting when I submit my form.
I beleive it has somthing to do with my results query below.
$result = mysql_query(select * FROM evdo WHERE Market like '%$term'
and Cell_Sect = '$cat' and Date = '$subcat' LIMIT 10);
Beow is my whole script for processing the form in case it maybe something else.
Thanks,
Chris

[PHP-DB] automactic email notification
I have an all-in-one form which allows record edits, adds and deletes
in a mysql table.
I would like to add the ability to automatically send email update to
a distribution list whenever a record is edited, deleted, or added.
I won't be hosting my own mail server so instead I will be using remote SMTP.
The mail script I created works just fine I am just not sure how to
put this all together for the notifications when the table is altered.
Thank you in advance!
Mail Script:
?php
require_once Mail.php;
$from = Someone email@.com;
$to = Someone Recipient email@.com;
$subject = Hi!;
$body = Hi,\n\nHow are you?;
$host = example.com;
$port = 587;
$username = example;
$password = example;
$headers = array ('From' = $from,
'To' = $to,
'Subject' = $subject);
$smtp = Mail::factory('smtp',
array ('host' = $host,
'port' = $port,
'auth' = true,
'username' = $username,
'password' = $password));
$mail = $smtp-send($to, $headers, $body);

[PHP-DB] jpgraph and mysql passing array
Hello,
I hope you can help me. The Jpgraph forum seems to be pretty
uneventful with participation.
I am trying to pass arrays through the image tag to populate my
variables for my graph.
I keep getting an error that there is no input. Do you have any suggestions?
I would greatly appreciate it! I have been trying to figure this out
for several hours.
Below is my code:
I need some help with finding a solution. For some reason my graph is
not showing up when it evident that my arrays are being passed.

Dear List -
Thank you for all your help. Here is another one.
I have a file [/home/ethan/PHP/RecNum] which consists of the number
1005. It also has been 1005. No matter how I do it, it is only
recognized as 1.
Here is the code. In this case, the file is 1005.
$fptr1 = fopen(/home/ethan/PHP/RecNum, r+);
$recNum = (int)fscanf($fptr1,%s);
echo $recNum; //which always is 1
If I do not typecast $recNum to int, the value is Array.
Right, which is what the manual says as well:
http://www.php.net/fscanf
If only two parameters were passed to this function, the values parsed
will be returned as an array.
So you can either do:
$line = fscanf($fptr1, %s);
$recNum = $line[0]; // get the first element in the array as $recNum
or
while ($line = fscanf($fptr1, %s\n)) {
$recNum = $line[0];

You can't do a full text match across tables.
One of the previous suggestions was to union the results, you end up
with something like
select field from t1 where match(field1, field2) against ('search term')
union all
select field from t2 where match(field3, field4) against ('search term')

Doesn't look like it should - it looks like a valid query.
Check your database logs or even run the query inside a transaction (and
rollback) to see if it errors.

Re: [PHP-DB] Slashes or no slashes
In the case that your comparing a field to a field in the database (the
field name)
do you escape that or because it is hardcoded you dont need to?
My thoughts are that you need to escape all data going in.
Correct. A field name is not data though. You've already validated it
(somehow, either by hardcoding it, or checking it against field names to
make sure it's a proper field and doesn't contain weird chars).
But I do not know if it will match.
EG:
/**
* updateProduct */
function updateProduct($ProductName, $field, $value){
$q = UPDATE .TBL_PRODUCTS. SET .$field. =
'.mysql_real_escape_string($value).' WHERE ProductName =
'.mysql_real_escape_string($ProductName).';
return $this-query($q);
}
Do I escape $field? mysql_real_escape_string($field)?
You can only escape data, not field or table (or database) names.

Re: [PHP-DB] Slashes or no slashes

Re: [PHP-DB] Slashes or no slashes
To be more specific. Is this correct?
function confirmUP($username, $password){
$username = mysql_real_escape_string($username);
/* Verify that user is in database */
$q = SELECT password FROM TBL-U WHERE username = '$username';
I normally do it in the query in case you use the variable somewhere
else but here it's ok because you don't use $username elsewhere. Be
careful though, it may bite you and it will be difficult to track down.
eg
$q = select password from table where username=' .
mysql_real_escape_string($username) . ';
echo You entered . htmlspecialchars($username) . , either it was
wrong or the password was wrong. Try again.;
Doing the escape_string before the query means you end up with (basically)
htmlspecialchars(mysql_real_escape_string($username));
which will cause weird characters to show up in certain cases.
$result = $this-query($q);
if(!$result || (mysql_numrows($result) 1)){
return 1; //Indicates username failure
}
/* Retrieve password from result */
$dbarray = mysql_fetch_array($result);
$dbarray['password'] = htmlspecialchars($dbarray['password']);
$password = mysql_real_escape_string(md5($password));
$password = htmlspecialchars($password);
You're not displaying the password so don't htmlspecialchars it.
Just:
if ($dbarray['password'] == md5($password)) {
return 0; // success!
}
Only specialchars it when you display it (like the echo above).

Perfect.
/* Retrieve password from result */

$dbarray['password'] = htmlspecialchars($dbarray['password']); //Or is

Leave it off.
You're not displaying $dbarray['password'] here - so you don't need to
use htmlspecialchars.

You're missing at least one brace.
If the code you supplied is a copy of what you have, you're missing a
} for the end of the while loop and one for the end of the else
condition.
So it's treating } else { as part of the while construct (and while()
doesn't have anything like an else condition).

Re: [PHP-DB] Building indexes
listread wrote: Chris, I just assumed that everyone on this list was using MySQL... That's what we're using (v. 5.1.45 GA) with InnoDB as the engine. Most people are but there are lots of types of databases out there :) (I just read your tutorial at http://www.designmagick.com/article/16/ It was very helpful - I look forward to checking out more of your articles.) If it is just as efficient to use multiple separate indexes, that would make index building less complicated on our large db. It is, though wildcard searches can't always use indexes. If you do field like 'abcdef%'; then an index can potentially be used because the db (mysql or otherwise) can look at the start of the string to see if it matches. The longer the string the more likely an index can be used (eg doing field like 'a%' probably won't use an index, it'll end up being quicker to scan the actual data). If you do field like '%abcdef%'; then an index can't be used since abcdef could appear anywhere in the string. Without a large dataset, it hard to truly test a system and if you have a large dataset, like we do, it takes quite a while to build indexes. Definitely, it's the best way to test and also the hardest since rebuilding the db takes so long. Our project is a petition signature validation suite. Since many of the handwritten names and addresses on petition sheets are difficult to read, the user needs to be able to do some fuzzy searching. Sometimes it's easier to read the address than it is the name. The zip code is usually easy to read. We almost always need to use LIKE queries, since some part of the name or address is typically hard to read. (We try to use as many of the leading characters as we can and wildcard the remaining.) I'd suggest fulltext but that won't work with innodb, only myisam. You could do something like keep the addresses and names in a separate myisam table just for searching, though that means a whole new import process and also means you'd end up having to do two queries (maybe a subquery or join, you'd have to test) - one do to full text search and one to get the rest of the data based on the result of the first.

I'm assuming your using mysql but that's just a guess. What database? (mysql, oracle, postgres, firebird, sqlite, other) If it's mysql, what db engine? Here are some questions: 1) If a query uses two or three fields is it best to prepare an index with those two or three fields, or will the query be just as efficient if we build three separate index, one for each field? Relates to above, but assuming mysql then it depends on what version. multicolumn indexes work well in all mysql versions. separate indexes can be used and combined in newer versions (v5 I think it came in). 2) Is the index building process any slower, per index, if you are building more than one index at a time? Most indexing I think takes an exclusive lock on the table, so index 1 gets created, index 2 has to wait it's turn until index 1 finishes.

Re: [PHP-DB] Cross reference query help
Ron Piggott wrote: The following is a query I am working on today. I need help tweaking on it. What I am trying to get for results from the query are where there are rows in either table, not all 3 tables linked together. In other words I am trying to INNER JOIN these two pairs of tables for possible results: `store_product_profile` and `paypal_cart_info` OR `store_product_profile` and `mail_order_cart` SELECT `store_product_profile`.`product_name` FROM ( `store_product_profile` INNER JOIN `paypal_cart_info` ON `store_product_profile`.`reference` = `paypal_cart_info`.`itemnumber` ) INNER JOIN `mail_order_cart` ON `store_product_profile`.`reference` = `mail_order_cart`.`store_product_profile_reference` WHERE `store_product_profile`.`discontinued` =0 AND `store_product_profile`.`reference` =7 Finally I need help with the GROUP BY syntax also. I only want the name of the product once, not if it was in several previous purchases. Any help is appreciated. So a product is either in the paypal_cart_info table or it's in the mail_order_cart table ? Though maybe this is a bad example - it's looking for reference=7 - you can check for that in your other tables since it seems to be a foreign key of some sort I'm guessing. You could use a union (or union all is probably better in this case) to bring them together. select itemnumber from paypal_cart_info where itemnumber=7 union all select store_product_profile_reference from mail_order_cart where store_product_profile_reference=7 put that into your other query and add your group by: select product_name from store_product_profile where reference in ( select itemnumber from paypal_cart_info where itemnumber=7 union all select store_product_profile_reference from mail_order_cart where store_product_profile_reference=7 ) and discontinued=0 group by product_name; If you put the check for '7' in the paypal and mail_order_cart tables it'll be faster than putting it in the bigger query. The smaller subquery will return less results (I'm guessing 0,1, or 2 results) and therefore the discontinued check will be quicker and so will the group by. If you don't put the check for '7' in the subquery, then mysql will have to go through *all* entries in paypal_cart_info and mail_order_cart (which may or may not be big tables), then make sure there is a reference entry in product_profile (which could be a pretty big table) and finally at the end of all that, check if reference '7' is in that list and it's not discontinued (then the group by etc). So in general, the further down the query chain you can put your where clauses to reduce the number of rows returned, the better. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If you put the images OUTSIDE of the webroot/docroot/public_html

the file.
e.g.
/home/sites/your_site/public_html/images/image1.jpg

But ...
/home/sites/your_site/public_html/getImage.php
/home/sites/your_site/hidden_images/image1.jpg
Now, there is no way I can load image1.jpg from my browser. I have to
use getImage.php, which I assume would require me to login or
authenticate myself in some way.

I have my photos in /public_html/img/gid directory and with this path:
img src='http://www.mydomain.com/img/{$gid}/{$photoFileName}' in getImage.php
the server displays the photos.
Now if I put my photos outside of the public_html like this:
/hidden_images/img/gid
what would be the correct path to the photos in the getImage.php script?
Do you mean what url? You'll need a script to pull them from outside the
document root. The advantage of this is you can do authentication checks
before displaying the image. The disadvantage is the web-server isn't
serving the images directly so there will be a slow down.
So you point your images to
getimage.php?image=123456
and getimage.php does your authentication checks if necessary then pulls
the image back using something like http://www.php.net/fpassthru

Good idea but you don't addslashes the whole query (and addslashes is
the wrong thing to use).
Use mysql_real_escape_string around bits and pieces you want to escape:

This works as far as populating the database, but my results page does
not return anything.
Only if the VALUES is set like this:

but some do not work with this setup. variables like $UserEmailVerified,
$UserRegistrationDate and $UserIP are not created from the form that was
submitted.
for example, User IP date is created like this.
$UserIP = md5($_SERVER[REMOTE_ADDR]);
Problem 1 is sql injection. Wrap each variable in a
mysql_real_escape_string call:
insert into table (...) values (' . mysql_real_escape_string($username)
. '
also quoting 'NULL' means it will add 'NULL' as the id - not what you
want. You can leave out the column to use the default from the database.
Any errors from mysql?
Add:
echo mysql_error();
after your insert call.
-
Below is a snip of how I retrieve the info on the result page (dont want
to clutter with whole code. also $fieldOne etc are MySql wildcards '%'
from some dropdown lists that show before this code is executed. The
results from adding show up fine there.)
$query_users = SELECT * FROM users WHERE UserID LIKE '$fieldOne' AND

UserPassword LIKE '$fieldFour' AND UserFirstName LIKE '$fieldFive' AND
UserLastName LIKE '$fieldSix' AND UserCompany LIKE '$fieldSeven' AND

UserCity LIKE '$fieldTen' AND UserState LIKE '$fieldEleven' AND
UserCountry LIKE '$fieldTwelve' AND UserZip LIKE '$fieldThirteen' AND
UserPhone LIKE '$fieldFourteen' AND UserFax LIKE '$fieldFifteen' AND
UserEmailVerified LIKE '$fieldSixteen' AND UserRegistrationDate LIKE
'$fieldSeventeen' AND UserVerificationCode LIKE '$fieldEighteen' AND
UserIP LIKE '$fieldNineteen' AND UserLastLogin LIKE '$fieldTwenty' LIMIT
$min, $max_results;
Again you need to escape all your data (except $min, $max_results - just
make sure they are always integers).
I'm assuming there are no errors reported by mysql.
To debug this, I'd simplify the query and work out which bit isn't
matching what you want (it could be $fieldOne isn't quite what you
expect, or it could be $fieldEleven or $fieldEighteen or ..).
Start off with one field, then add another and go from there.

You're not getting '2' because the second part is returning 0.
I substituted dummy variables for your subqueries (select 1 and select 2).
SELECT COUNT( * )
FROM `verse_of_the_day_Bible_verses`
WHERE seasonal_use =2;
What does that return by itself?
that is what your query will run instead of my 'select 2'.
That in turn goes into the
select least(14, result_from_above_query);
and takes that away from date('2009-12-25');
If the current date is not in that range, it will return 0.
Here's the second part of your query isolated for you to test:
SELECT
IF
(
CURDATE() =
DATE_SUB(
DATE('2009-12-25'),
INTERVAL LEAST(14, (SELECT COUNT(*) FROM

Did you try names with single quotes? (Tim O'Reilly is a common example
to try).
But when I would view results, it didnt read anything from the database.
Sure it went in? Did you see the data when you viewed the table in
phpmyadmin or some other tool?
Again you need to escape all your data (except $min, $max_results -
just make sure they are always integers).
Those are so I can control the number of items shown per page.
I realise that. mysql_real_escape_string is used for data in your query,
and may cause problems if used in limit clauses. If you end up with this
for example:
select * from table limit mysql_real_escape_string('blah');
of course it's not going work.
Hence the check to make sure $min and $max_results are int's before
passing them to the query so if anyone messes with them it won't break
your queries.
if (!is_int($min)) {
$min = 0;
}
if (!is_int($max_results)) {
$max_results = 5;
}
Basically the result page would not show anything in the database unless
it was inserted in the database using the $_POST method.
That still suggests an error with the insert.

A mysql query would do it but you'd use something to talk to mysql and
process the results (whether it's php, perl, python, ruby etc depends on
your other requirements).
What I'm trying to do is to have a record picked from the database at random
on the 1st of every month and display it on the page. Here is some code I have
been working with:
$query = SELECT DATEADD(mm, DATEDIFF(mm,0,getdate()), 0);
$result = @mysql_query($query);
if (!$result){
$query = SELECT * FROM monthlyPooch ORDER BY RAND() LIMIT 1;
$result = @mysql_query($query);
while ($row = mysql_fetch_array($result)){
echo $row[poochName] ;
echo $row[Birthdate];
}
}
You can check the day of the month in php then do your other query:
$today = date('j');
if ($today !== 1) {
echo Today isn't the first. No need to continue.\n;
exit;
}
..
random query etc here.
