Wow...someone else that hasn't used it...I thought I was the only one in this day and age.

You're off-topic. This is the Perl forum. You may want to check out the Python[^] forum. I just took a peak, and a well-known CP regular has already posted there. He can probably give you a hand with your Python questions.

which apparently isn't much since there isn't any other activity yet.

Python, sounds like a pet to me 
but on a more serious note, all i know is that python is a scripting language. What exactly does that mean? why would i as a C# developer use python for?

see my response under "what is python's claim to fame?". The only reason not to learn Python is that once you do so much of C# will drive you insane,... that has certainly been my experience

Some background: I have taken a few measures to prevent SQL injection on my PHP/MySQL setup (currently WAMP for development, but will be LAMP for production server):
- In my users table, I have entered a "bad" user, with all the fields equal to 0.
- this is the first user in the table
- if a hacker tries to enter ' or ''=' in the uname field:
- (theoretically,) "bad" user will be first result, and
- (theoretically,) # of results will also be greater than 1 (more than 1 user)
- (theoretically,) the following code will prevent said hacker from gaining unauthorized access
- mysql_real_escape_string() function will be used to escape input when site is launched, but right now it is not in use to allow testing of common SQL injection methods.
- I have read that mysql_real_escape_string() has some vulnerabilities.
- I know mysql_real_escape_string() is more secure than addslashes().

} else <span style="color: blue">$loginError</span> .= <span style="color: red">"Error: Invalid username and/or password."</span>;
I dunno... maybe I'm just paranoid... I just want to make sure to CMA to prevent liability problems, since this will be a commercial site.
P.S. I hope the markup helps read my programming - I know my lines tend to be fairly long...

To prevent SQL injection all you need to do is escape and use good validation. Other stuff can be a waste of time.

I usually use this function to prevent SQL injection, maybe it's useful for you :
function quote_smart($value)
{
if (get_magic_quotes_gpc())
{
$value = stripslashes($value);
}
if (!is_numeric($value))
{
$value = mysql_real_escape_string($value);
}
return $value;
}

Like using parameters instead of inlining?

What level of validation is enough?
I think that using prepared statements with parameters is the safest way, what do you think ?
|
|

SQLi is best handled using the database's native escaping routines and not just relying on addslashes() -- there is actually a way to circumvent addslashes from what I remember.
Filtering is probably a good practice as well.
To avoid escaping, you could just use PDO and prepared statements which handles the escaping for you automagically as well.
I'm finding the only constant in software development is change it self.

Hi friends.
I usually use Smarty to create templates.
When I wanted to create somethings like this :
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Test</title>
</head>
<body>
<table>
<tr>
<td> </td>
</tr>
</table>
<table>
<tr>
<td> </td>
</tr>
</table>
<table>
<tr>
<td> </td>
</tr>
</table>
<table>
<tr>
<td> </td>
</tr>
</table>
</body>
</html>
I created three files ( for example Header.tpl , Footer.tpl , Body.tpl )
Header.tpl :
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Test</title>
</head>
<body>
Body.tpl :
<table>
<tr>
<td> </td>
</tr>
</table>
Footer.tpl :
</body>
</html>
Then I wrote this Smarty code in PHP to created above HTML file :
$smarty -> display('Header.tpl');
for ($i=0; $i<=3; $i++)
$smarty -> display('Body.tpl');
$smarty -> display('Footer.tpl');
This way is bad, because designing template is very difficult.
Are there any ways to use Smarty and create above HTML file.
Thanks in advance

Can't you just output the HTML? It doesn't stop normal PHP from working.

With Smarty you can sift Template through program , so we can change template easily.

Ok, well sorry I haven't really looked into Smarty so I'm not going to be of too much help. Check out the Smarty Forums[^]. They can probably help you out.

Can you tell us what happens? Does it through errors? Can you show us the code?
