Question

I am using query for joomla.

$query = "INSERT INTO '#__demo'( 'id', 'fname', 'mname', 'lname' ) VALUES ( '$val', '$post['fname']', '$post['Mname']', '$post['Lname']' );";

It is giving error

syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING 

Answer 1

There are two mistakes on your query.

1. You haven’t escaped your quotes in $_POST values.

   '$post['fname']'
   //     ^ here and other places
   

2. You are using single quotes ' to represent tables and field names.

    .. INTO '#__demo'( ..       
   //       ^ here and other places
   

Now after removing all such problems. You query becomes:

$query = "INSERT INTO `#__demo` ( `id`, `fname`, `mname`, `lname` ) VALUES ( '$val', '$post[fname]', '$post[Mname]', '$post[Lname]' );";
