PHP Fatal error: Call to a member function bind_param()
$statement= $db->prepare("insert into uploaddetails(idnum,title,desc,author,tags,title) values(?,?,?,?,?,?)");
$id='NULL';
$title=$_POST['title'];
$description=$_POST['description'];
$author=$_POST['author'];
$tags=$_POST['tags'];
$file= basename($_FILES["fileToUpload"]["name"]);
$statement->bind_param( 'isssss', $id,$title, $description,$author,$tags,$file);
$statement->execute();
$db->close();
$statement->close();

Answer 1

Since nobody else has spotted the issue, I'll post it for you. The reason you're prepare() is failing is because you're trying to use a MySQL Reserved Word. The word desc is a reserved word in MYSQL, which means you need to wrap it in backticks like this:
$statement= $db->prepare("insert into uploaddetails(idnum,title,`desc`,author,tags,file) values(?,?,?,?,?,?)");
It also helps to use proper practice when inserting into a database/using prepared statements.
$statement= $db->prepare("insert into uploaddetails(idnum,title,`desc`,author,tags,title) values(?,?,?,?,?,?)");
if($statement !== FALSE) {
// do the binds...etc
}
Notes
file is also a reserved word, I don't know what your actual file columns name is, so keep that in mind.

Answer 2

Your prepare statement is failing because of the query, what you need to do is to make sure the statement is not false in order to execute bind_param, otherwise view the prepare query error as follows :
//Make sure the statement is not false
if($statement !== FALSE)
{
$statement->bind_param( 'isssss', $id,$title, $description,$author,$tags,$file);
$statement->execute();
$db->close();
$statement->close();
}
//Otherwise check why the prepare statement failed
else
{
die('prepare() failed: ' . htmlspecialchars($db->error));
}

Answer 3

Try this. your code is modified.
$statement= $db->prepare("INSERT INTO uploaddetails (title,desc,author,tags,file) VALUES(?,?,?,?,?)");
//$id='NULL';
$title=$_POST['title'];
$description=$_POST['description'];
$author=$_POST['author'];
$tags=$_POST['tags'];
$file= $_FILES["fileToUpload"]["name"];
$statement->bind_param( 'isssss',$title, $description,$author,$tags,$file);
$statement->execute();
$db->close();
$statement->close();
//---- Move the file to desired location...
-ID is not required because it is auto increment and mysql will take care of it,
-and you had wrong field name for file, which was title and I change it to file(correct it if you have any other name instead).

Answer 4

possible errors
1)column count in the table is different from your query.
2)although it shows the error in the bind_param line, the error may occur in the prepare statement line(in your case line 1)
3)you can put echo statement before and after these lines and caught the error
(in my case I repeated the same field name twice in the prepared statement)
fetch following code with your requirements and tryout
$stmt = $conn->prepare("INSERT INTO SalesReturn(CRDNUMBER, CRDDATE, REFERENCE,CUSTOMER,ITEM,QTYRETURN,UNITPRICE,TIAMOUNT1,TIAMOUNT2,EXTCRDMISC,TAMOUNT1,TAMOUNT2,CRDSUBTOT,CRDNET,CRDETAXTOT,CRDNETNOTX,CRDNETWTX,TransactionType) VALUES (?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)");
echo "after prepare";
$stmt->bind_param("ssssssssssssssssss",$CRDNUMBER,$CRDDATE,$REFERENCE,$CUSTOMER,$ITEM,$QTYRETURN,$UNITPRICE,$TIAMOUNT1,$TIAMOUNT2,$EXTCRDMISC,$TAMOUNT1,$TAMOUNT2,$CRDSUBTOT,$CRDNET,$CRDETAXTOT,$CRDNETNOTX,$CRDNETWTX,$TransactionType);
echo "after bind_param statement";
