mysql_real_esca pe_string/htmlentities issue

<?php
//MAKE IT SAFE
$chunk = $_POST['foo'];
$title = $_POST['foo1'];
$url = $_POST['foo2'];
$tags = $_POST['foo3'];
$user = $_POST['foo4'];

$safe_chunk = mysql_real_esca pe_string(htmle ntities($chunk) );
$safe_title = mysql_real_esca pe_string(htmle ntities($title) );
$safe_url = mysql_real_esca pe_string(htmle ntities($url));
$safe_tags = mysql_real_esca pe_string(htmle ntities($tags)) ;
$safe_user = mysql_real_esca pe_string(htmle ntities($user)) ;

mysql_query("IN SERT INTO chunks VALUES ('$safe_chunk', '$safe_title',
'$safe_url', '$safe_tags', '$safe_user', CURDATE(), '')");

I guess an explanation is in order! The problem is that the values
aren't put in the database. I just get blank fields instead.

First of all, you shouldn't use htmlentities here. That's for
displaying the data, not storing it in the database. Rather, use it
after retrieving the data but before displaying it.

Next question is - what's in the $_POST array? Try

echo "<pre>\n";
print_r($_POST) ;
echo "</pre>\n";

Finally, what's the result from mysql_query? ALWAYS check the result of
a mysql call (or any other external call, for that matter). If it is
false, display the error with mysql_error().

Hello, My php.ini file currently has magic quotes set to On, but I have read that it is better to code with it off. Currently with magic quotes on, I only use stripslashes() to properly format strings that are displayed on the screen. I know that now with magic quotes off, I will have to manually handle escaping special characters with mysql_real_escape_string() or addslashes().

Hi all, I was hoping to get some clarification on a couple of questions I have: 1) When should htmlspecial characters be used?

Can someone please explain to me why/when one would use htmlspecialchars instead of htmlentities? I know: if you only want to get certain characters translated. This is not the answer I'm looking for, I would like to know *why* you would want that, as opposed to a full translation.
