vbulletin input clean classes

Hi,

I am trying to make a vbulletin powered custom page which is a html form.
The user fills the form and the data is entered into the database.

I use the database classes of vBulletin to connect to the database and insert values. My problem is that i use a insert statement as

$var1 = $_REQUEST["var1"];
INSERT INTO TABLE VALUES (1, '$var1');

Now, if $var1 already contains a single quotes, i get an database error on submitting the form. Is there some class of vBulletin that i can use to insert the data into the database so that the database stores ' as well.

Also, is there a easy way to prevent SQL injection?

Thanks

I figured how to escape the single quotes error. I used the following code

Code:

$vbulletin->input->clean_array_gpc('p', array(

                'name'                => TYPE_STR,

                 'category'      => TYPE_NOCLEAN,

                 'contact'    => TYPE_STR,

));



$db->query_write("INSERT INTO table (id,name,category,contact) values ('','". $db->escape_string($vbulletin->GPC['name']) ."', '". $db->escape_string($vbulletin->GPC['category']) ."','". $db->escape_string($vbulletin->GPC['contact']) ."')");      



eval('print_output("' . fetch_template('testtemplate') . '");');

But i have a problem with the blank lines. For example, contact is actually a textarea where the user can enter blank lines. I need the database to store the <br> as well. When i retrieve the information from the database and print it on html, i want the text to have the same formatting as it had when the user submitted the form.

I hope my question is clear.

Please help me

Use the function

nl2br() after it is retrieved from the database.
