// Define post fields into simple variables
$text = $_POST['text'];
$message = $_POST['message'];
/* Strip some slashes in case the user entered any escaped characters. */
$text = stripslashes($text);
$message = stripslashes($message);
You get the idea. Later on in the page error checking on the form posted fields are called (for empty fields), the information is sent to the database, an email with the info is sent, etc.
Here's the problem. If the user types an apostrophe, the information is not submitted and the user gets the error, "You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '....". After doing a little research, I read that I had to check my magic quotes. I found this:
magic_quotes_gpc On On
magic_quotes_runtime Off Off
magic_quotes_sybase Off Off
I am on a shared server and do not have access to server settings.
What do I need to do to allow a user to enter an apostrophe in a text box or textarea? The strange thing is I don't think I get the error when quotes are entered.
As the information is added to an email, I don't want slashes to be added before every apostrophe.
Thank you so much!
$emailtext = stripslashes($text);
$emailmessage = stripslashes($message);
then use $emailtext and $emailmessage in the part of you script that sends the mail.
The thing is, though, when you formulate a query that uses some of this user input, you need to put those slashes back in again. Use mysql_real_escape_string() if you have version 4.3 or more or mysql_escape_string on each part that contains user input, and put quotes around these strings as necessary.
I still am unsure of what I need to do. I did see mention of mysql_real_escape_string() in some readings, but I am not sure what that means, where and how it should be coded, etc.
I also saw some suggestions on how to set an htaccess file to turn magic quotes off, but I am not sure if this is desirable. Also the code I saw did not follow the format of an htaccess file.
I still need help!
If the database does not show the slashes, is there any kind of problem when I query the database? I had such a problem getting it into the database, will I have a problem getting it out of the database?
