pb PHP using mysql prepare statement

**fomalhaut** · 11-02-2009 09:36 AM

Hello.

I want use prepare statement for a mysql insert statement but I have the following error :
Parse error: syntax error, unexpected ':' in C:\xampp\htdocs\fomalhaut\gesUtil.php on line 2
I don't understand really how do I link this $dbh with my database which would already connected ?!

PHP Code:


<?php session_start(); 
  $ins = $dbh->prepare("INSERT INTO ayant-droit (utilisateur, upass, service, creation, limite, RV) VALUES(?, ?, ?, ?, ?, ?)");
  $ins->bindParam(1, $utilAGerer);
  $ins->bindParam(2, $paAgerer1);
  
  $ins->bindParam(3, $servAGerer);
  $ins->bindParam(4, $creDateAGerer);
  $ins->bindParam(5, $revDateAGerer);
  $ins->bindParam(6, $RV);

1.

PHP Code:


session_start(); 

  $ins = $dbh->prepare("INSERT INTO ayant-droit (utilisateur, upass, service, creation, limite, RV) VALUES(?, ?, ?, ?, ?, ?)");

 

.....

 

  $con = mysql_connect("localhost", "user**", "pw**");

$db  = "jyc_ayantdroit";

if (!$con) {die('Connection impossible : ' . mysql_error());}

mysql_select_db($db, $con);

Where does $dbh come from, especially if you are connecting to the DB later on?

2. And I think you changed something between the error and posting here.

Parse error: syntax error, unexpected ':' in C:\xampp\htdocs\fomalhaut\gesUtil.php on line 2

There is no ':' even close to line 2 and when I cut a paste your code, that parse error does not occur.

Hmmmmmmmm.. Wild guess. 'gesUtil.php' is a file you include, but you did not show the include in what you posted. And gesUtil.php is where you get $dbh. And there is probably a ':' in the first couple of lines of gesUtil.php which is unexpected because there is a missing { or ( or " .

Further guess: there's a colon rather than a semicolon at the end of the line.

  $ins->bindParam(1, $utilAGerer);

  $ins->bindParam(2, $paAgerer1);

  

  $ins->bindParam(3, $servAGerer);

  $ins->bindParam(4, $creDateAGerer);

  $ins->bindParam(5, $revDateAGerer);

  $ins->bindParam(6, $RV);

?>

At this point, none of the variables you're binding params to (e.g. $utilAGerer) are defined. Either move these lines after you set the variables or pass the values to PDO::execute (which you seem to be using):

PHP Code:


$ins->execute(array($utilAGerer, $paAgerer1, $servAGerer, $creDateAGerer, $revDateAGerer, $RV));

mysql_select_db($db, $con);



// on regarde si l'utilisateur à gérer existe

$check = mysql_query("SELECT * FROM ayant_droit WHERE utilisateur = '" . $utilAGerer . "'")

or die(mysql_error());

Don't neglect to prepare this query using the same connection you used for the INSERT.

There should be only one line in one script that's responsible for creating a DB connection. The more scripts contain user credentials, the more files there are for you to secure and the greater chance of typos screwing things up. Reduce critical code repetition.

die() is a bad choice, both here and when you test that all user input is defined. Use an "if {...} else {...}" statement or exceptions. You can configure PDO to throw exceptions when errors occur:

PHP Code:


$dbh = new PDO("mysql:host=localhost;dbname=$dbname", 'username', 'password');

$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

Hello

I'm very ashamed of myself, sheepish, and confused !!!! :dunno:

The error message I gave was not the one corresponding to the code I joined !

Sorry...

Descalzo, you're right ! this isn't the good message ! The real message was :

Fatal error: Call to a member function prepare() on a non-object in C:\xampp\htdocs\fomalhaut\gesUtil.php on line 2

However, I've not poured down too much whisky in my milk, that morning ! :drool:

But this is now resolved :

I had misplaced the db connect, which was bad written !

I've write it now before the "prepare" statement, with your example, Misson... and of course, that works fine !!!

I thought the dbconnect made in the previous php file was enough !

Delcazo, Misson, thank you very much again and forgive me for my drivel !
