Question : MySQL Query

I have set up a html form:
<FORM ACTION="http:// -----------" METHOD="post">
<INPUT TYPE='text" NAME="quest" SIZE="40" MAXLENGTH="100" VALUE="" />
etc.
and a php file that contains
$query = $_POST['quest'];

The idea is that an SQL Query is typed in as text and then that is passed to the php file which executes the query. It works sometimes, but doesn't work most of the time --- evidently that $_POST doesn't capture the query just as typed. (The php program works fine if I type the query in.

This is my first question to Experts-Exchange.

Answer : MySQL Query

You have to add :

foreach($_POST as $name => $value){
if(get_magic_quotes_gpc()==1){
$_POST[$name] = stripslashes($value);
}else{
}
}

at the beginning of the php code, so finally :

(this file has to be named index.php because the post method posts to itself, or change the form action to the file)
