In your code, it appears you forgot to close a pair of parentheses:
---
foreach($set as $key=value)
{
if (array_key_exists($key,$this-titles)
{
$this-a[$key] = $value;
}
}
---
It looks like that 3rd line should be:
---
if (array_key_exists($key,$this-titles))
---
I hope that helps. Having another set of eyes take a look at it usually
does. ;)

Yeah, just a joke. I forgot to put the Trademark ;-P in its place.
The etymology of that message could be attributed to the fact that
Zeev and Andi are Israeli. Just taking a guess at it though.

Re: [PHP] Validating Form input
I completely agree, server-side validation does always have to exist.
That said, I like providing feedback on the validity of a form before
the user leaves the page AND I hate duplicating the validation logic
in Javascript when it's already present in my PHP.
What I did in my PHP framework (probably framework 2 billion and 1)
was set it up so you can use REST-ful calls to the PHP page that
contains the validation so you can retrieve the results of the
validation, allowing you to render whatever feedback you'd like on the
calling page through AJAX, or allow the request to proceed if it was
valid. Additionally, I've set my framework up so it chunks web pages
into various sections ('pipes'), allowing for REST-ful calls to the
PHP page that contains a pipe to easily render the HTML fragment
associated with a particular section, so you can progressively enhance
pages with javascript quite easily.
I'm pleased with this approach after using for it for a while now, and
I recommend it to others.

I was wondering what others think of my approach to form
validation. I know many use Java script to do various validation.
However, since there is no way to be sure the data sent to the
server is actually valid, you have to check it in your php code on
the server anyway. Granted you don't have to, but if you don't, you
are just asking for someone to hack your system, or at the very
least screw up your data. So my question is since you have to do a
validity check on the server, why bother with the Java script? The
only advantage I can see to doing it with Java script is it will cut
down on the errors in data that get to the server and then in turn
reduce the number for resubmits and keep traffic down a little.
However since none of the projects I have worked on are very high
traffic sites, that hasn't been much of a concern.
Any thoughts?

Re: [PHP] Using SVN w/ Zend Studio for Eclipse
I do not want to copy the project into a new directory as the existing directory is where Apache's DocumentRoot is set. And although that's simple to change, I really don't think any IDE should mandate where I set my project's directory on the filesystem. I use PDT, and there is no problem to import a project from its current location. It might take you a while to exactly figure out how to do it, Eclipse is a bit organic in respect to the organization and working of the menus. Also, if I try to create a new project from an SVN Repository, it doesn't allow me to select what directory I want the code checked out in. This works very well with PDT and Subclipse. Otherwise I'd just cringe and let it overwrite what's in my existing document root, since that's all versioned code anyhow. If your current document root is a checked out svn project, PDT/Subclipse will see this, no need to overwrite anything. If any of you have run into similar frustrations, I'd love to hear it. So far I've spent the better part of the evening fiddling with extremely rudimentary features which no IDE in any programming environment I've ever worked with has imposed on me. Perhaps this thing isn't ready for mainstream yet, or perhaps I'm missing something obvious. Again, I work with PDT/Subclipse. Eclipse is simply too organic compared to what you are used to.

Re: [PHP] Variable Scope from child to parent
Ok, I forgot to reply-all to the list. Here we go again.

I am trying to get a child class to pass an array of valid keys to it's

later. I have tried explicitly stating the variable scope.

Unfortunately it seems to duplicate the child's array instead of appending.
Explicitly stating scope does not seem to help.

Array (

[1] = titleB
[2] = titleB
[3] = titleA
[4] = titleB
[5] = titleB
)

Array()
Any thoughts?
A couple. First, as Gabriel said, replace self::$this- with just
$this-. Second, the protected variable $vkeys in the childclass
effectively overwrites the variable of the same name in the parent
class, so it already has the values you are trying to merge
(array('titleA', 'titleB', 'TitleC')) when the childclass is
instantiated before you even call the constructor. That's why the
constructor duplicates the values. Try this for the constructor for
your childclass:
function __construct($set, $special = array())
{
$merged = array_merge($special, array('titleA', 'titleB', 'TitleC'));
parent::__construct($set, $merged);
}

It could be as simple as tags that don't close in HTML (e.g. img, br, hr) or it could be something much trickier to clean up such as mismatched tags, improper nesting, missing closing tags (since some browsers are too forgiving of not closing td, li or option), HTML entities that are not valid in XML, etc. In these cases, the DOM-type parsers will usually choke. You might be able to salvage something with the stream-based parsers like SAX. (I've never tried it.) Andrew

Re: [PHP] Validating Form input
At 9:48 PM -0500 5/14/08, Chris W wrote: I was wondering what others think of my approach to form validation. I know many use Java script to do various validation. However, since there is no way to be sure the data sent to the server is actually valid, you have to check it in your php code on the server anyway. Granted you don't have to, but if you don't, you are just asking for someone to hack your system, or at the very least screw up your data. So my question is since you have to do a validity check on the server, why bother with the Java script? The only advantage I can see to doing it with Java script is it will cut down on the errors in data that get to the server and then in turn reduce the number for resubmits and keep traffic down a little. However since none of the projects I have worked on are very high traffic sites, that hasn't been much of a concern. Any thoughts? Use javascript to enhance the user experience, but always validate server-side. If you are clever, you can tie the two together via ajax and present a nice data collection scheme that is both user-friendly and secure.

for something very simple how about add a drop down list for each item:
[chooose position..]
{ - before task 1 }
{ - before task 2 }
{ - before task 3 }
{ - before task 4 }
{ - at the end}
and when user clicks save, the php side will do it's magic and update.
i think there is a limitation especially if the user decides to
reorder many items. but then if you are handy with the javascript/ajax
then just do a visual update which can make it easier for the user.

[PHP] question about validation and sql injection
A) validating username in php
as part of a registration form a user fills there desired username and this
is stored in a mysql. there are certain conditions for the username.
a) the username should only begin either letters or numbers, and Underscore
character
example = user123, 123user, u_ser123, user_123 = completely case insensitive
b) a user may choose not to have an underscore or numbers sometimes. example
= username
presently my validation for username is
$username = $_POST[username];
if( $username == || !eregi(^[a-zA-Z0-9_]+$, $username) )
{
$error.=User name cannot be blank or has special characters;
}
Question = how can i rewrite this php validation for username to meet the
above criteria or is my validation correct
B) preventing sql injection
till now i have been capturing the form values and directly inserting into
the table without considering sql injection however for this project as it
is for a forum i would like to implement prevention of sql injection. from
what i have read about preventing sql injection there are several steps that
need to be followed,
htmlentities
addslashes
trim
mysql-real-escape-string
magic_quotes_gpc is ON
magic_quotes_runtime is OFF
magic_quotes_sybase is OFF
as i have not done preventing sql injection i am not sure what is the
correct process.
Question =
a) please advice a step by step process of how to go about avoiding the sql
injection before the insert sql query is executed starting from
$username = $_POST[username]; till the
insert into tablename(field1, field2) values($value1, $value2) SQL query is
executed which will prevent sql injection even if the user enters any
special characters while filling the form.
b) should i consider the setting of magic quotes as in should it be ON or
OFF or should i ignore it if so should it be
ON or OFF
c) also with the prevention methods if a user types a special character in
the data will that character be written in the table as a escaped character
or how does it store those special characters
d) a very important point here, i have a feature where a user can check if a
username is available or not. so while storing a username if the username is
stored as john\smith in mysql and if the user is searching for johnsmith
this would not match, so even in the table the username should be stored
without slashes as i have to read the username and compare with what the
user has typed to see if they both are same or different.
please advice if i have missed any other steps to prevent sql injection.
thanks a lot for your help.

I am assuming that each time you click the up or down arrow you are
re-loading the page (via a GET request). A simple solution to this, would
be to adjust the URLs assigned to the up and down arrows to carry an extra
variable, the item either directly above or directly below the one selected,
and instead of doing whole-sale renumbering, create a swap function. That
just swaps the position of the two items.
example:
?php
$rows = get_items_in_list();
for ($i = 0 ; $i count($rows); $i ++) {
echo $rows[$i]['taskname'].nbsp;;
// create move up link
if ($i 0) {
echo 'a
href=page.php?this='.rows[$i]['position'].'other='.$rows[($i-1)]['position'].'move
up/anbsp;';
}
//create mode down link
if ($i (count($rows) -1)) {
echo 'a
href=page.php?this='.rows[$i]['position'].'other='.$rows[($i+1)]['position'].'move
up/abr/';
}
}
?
Then your page would just have to watch for those two variables being set at
load and select the appropriate items in the database based on the order and
swap their two positions, this will allow you to handle gaps in the
positioning scheme, for example when you are only listing the status 1 items
and not all the items.
*note* The code above is completely off-the-cuff and not tested, don't blame
me if there are any bugs in it ;)

[PHP] fsockopen + fputs
Hello,
I use fsockopen and fputs to call a distant URL, but I have the following
error :
The requested URL /registration/test was not found on this server.
This is my code:
$req =
'username=' . $usr . 'password=' . $pass .
'date_of_birth=' . $year . - . $month . - . $day .
'email=' . $email . 'country=' . $country;
$fp = fsockopen(www.example.com, 80, $errno, $errstr, 30);
if (!$fp) {
echo $errstr ($errno)br\n;
} else {
$header = POST /registration/test HTTP/1.0\r\n;
$header .= Content-Type: application/x-www-form-urlencoded\r\n;
$header .= Content-Length: . strlen($req) . \r\n\r\n;
fputs ($fp, $header . $req);
while (!feof($fp)) {
echo fgets($fp, 1024);
}
fclose($fp);
}
However the path www.example.com/registration/test exists
so why does it says it cannot find the requested url ?
Any idea ? Thank you for any help !!

Re: [PHP] question about validation and sql injection
your validation looks good enough to me. If you only allow
alphanumerical chars, then your should not be worried about sql injection
also use addslashes($username) before you insert into database and you
should be fine.
Usually addslashes is enough to prevent this, but the validation that
you have is also enough. So if you worried about the sql injection, then
use both and you should be fine.

[PHP] Re: question about validation and sql injection
Sudhakar wrote: A) validating username in php If you do what needs to be done to prevent sql injection, it doesn't matter what you let users have for their user name. B) preventing sql injection htmlentities this has nothing to do with sql injection it just is needed so when you print data to the screen that may include html entities, they display right. addslashes This is a generic way to escape things and is a bad idea since it doesn't know what system you are using for your DB so you can't be sure it does it right. trim This is handy when reading form data just so you don't store any extra spaces at the beginning and end of entries. Often users will inadvertently add a space to the end or have spaces the come in from copy and paste. Again nothing to do with sql injection. mysql-real-escape-string If you are using MySQL this is the only function you need to prevent sql injection. Simply run any variable that will be part of a query through this function and then put single quotes around all variables in your queries and sql injection will be a non issue. Example $UserName = mysql_real_escape_string($UserName); $query = SELECT * FROM `user` WHERE `UserName` = '$UserName' ; run the query and all will be good. Many add the password to the where clause too but I prefer to use a php if statement to be sure the comparison is case sensitive (depending on the Collation you use in MySQL your conditional tests may or may not be case sensitive). magic_quotes_gpc is ON If you can, you should have this off. In php 6 Off will be the only option. With it on it adds slashes in an attempt to do a generic escape of characters to prevent sql injection. Since you can't be sure that will work right, the best bet is to read in your form data like this $UserName = trim(stripslashes($_POST['UserName'])); I do the same thing for all data read from forms. Then before I use the var as part of a query, I use the mysql_real_escape_string function on it. The only exception is when I am expecting an integer returned from a form, in which case I use this... $Status = (int) $_POST['Status']; that way no mater what the user or some hacker tries to get in, I am sure $Status contains an integer and I don't need to bother with the mysql_real_escape_string on that var. If magic_quotes_gpc is off, you can and should remove the strip slashes function call. Note the only reason I use trim is to get rid of any white space that may be at the ends of the string. magic_quotes_runtime is OFF magic_quotes_sybase is OFF These should both be off too. -- Chris W KE5GIX Protect your digital freedom and privacy, eliminate DRM, learn more at http://www.defectivebydesign.org/what_is_drm; Ham Radio Repeater Database. http://hrrdb.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

If I understand you right the problem is because you are showing a list
of items with the status of todo and there are other items with a status
of done, that if shown would have a priority in between the the ones
with a status of todo. So if you simply swithch the priority value with
the next record up in the priority order, it may not move because of
unseen items with the done status.
I have had this problem before but in much different type of
application. Basically you have several groups of records in the same
table and you want to sort them independent of each other. What I have
done is to specify what field(s) in the table define each group. In my
case I have often had 1 2 or even 3 fields needed to define the groups.
In your case it is just the todo / done status field. What I do is
have the up and down arrow and have the link pass the ID of the item I
want to move, the sort order value(priority in your case), the value(s)
of the group field(s) and the direction I want to move the item. So the
url for the move button would be something like this
Status ToDo = 1
Status Done = 2
ID of Record to move is say 34
priority of record 34 is say 21
Record has a status of ToDo.
Move.php?ID=34Order=21Status=1Move=Up
Then the move function does something like this.
if($Move == 'Up){
$query = SELECT ID, Priority FROM `todolist \n;
$query .= WHERE `Priority` '$Order' AND `Status` = '$Status' \n;
$query .= ORDER BY `Priority` DESC \n;
$query .= LIMIT 1 \n;
}else{
$query = SELECT ID, Priority FROM `todolist \n;
$query .= WHERE `Priority` '$Order' AND `Status` = '$Status' \n;
$query .= ORDER BY `Priority` \n;
$query .= LIMIT 1 \n;
}
run query
$TempID = $row['ID'];
$TempPriority = $row['Priority'];
$query = UPDATE `todolist` SET `Priority` = '$Order' \n;
$query .= WHERE `ID` = '$TempID'
run query
$query = UPDATE `todolist` SET `Priority` = '$TempPriority' \n;
$query .= WHERE `ID` = '$ID'
run query...
