[php] Erreur fatale : Types d'opérandes non supportés

I suspect that it comes from a problem with the array addition; what I don’t understand is how this array was created. Indeed, I had to change names and remove a space for the issue to be fixed, and that’s really what’s bothering me.
But thanks for your explanation ^^

Hello

Well, here are some explanations

I suppose the excerpt below comes from var_dump($_SESSION) unless I'm mistaken

["jours"]=> &array(6) { [1]=> array(7) { [1]=> string(0) "" [2]=> int(1) [3]=> int(2) [4]=> int(3) [5]=> int(4) [6]=> int(5) [7]=> int(6) }

$_SESSION is an associative array that holds all the session variables

["jours"]=> &array(6)

The variable "jours" is of type array, so it basically refers to an array (hence the ampersand & before)
that contains 6 elements

[1]=> array(7)
The element "1" of the "jours" array is itself an array of 7 elements

If we write $jours=$_SESSION["jours"]
then $jours[1][1] contains an empty string which corresponds to

["jours"]=>
&array(6) {
[1]=>
array(7) {
[1]=>
string(0) ""

Now, when you write
$travail=$_SESSION['jours'];
$travail=($travail+$count);

in $travail you have an array and in $count I don't know... the bottom line is that you can't add an array with another variable because it doesn't make sense, so $travail+$count fails with your error message: unsupported operand type, which is logical since generally addition operates on numbers. D'Oh!

Thank you for your response, I'm getting some weird stuff that I don't really understand, I'll put it here:

 ["ident"]=> &string(32) "ea5fdbf44f86b785707b62753207a015" ["compte"]=> ∫(1) ["jours"]=> &array(6) { [1]=> array(7) { [1]=> string(0) "" [2]=> int(1) [3]=> int(2) [4]=> int(3) [5]=> int(4) [6]=> int(5) [7]=> int(6) } [2]=> array(7) { [1]=> int(7) [2]=> int(8) [3]=> int(9) [4]=> int(10) [5]=> int(11) [6]=> int(12) [7]=> int(13) } [3]=> array(7) { [1]=> int(14) [2]=> int(15) [3]=> int(16) [4]=> int(17) [5]=> int(18) [6]=> int(19) [7]=> int(20) } [4]=> array(7) { [1]=> int(21) [2]=> int(22) [3]=> int(23) [4]=> int(24) [5]=> int(25) [6]=> int(26) [7]=> int(27) } [5]=> array(7) { [1]=> int(28) [2]=> int(29) [3]=> int(30) [4]=> int(31) [5]=> string(0) "" [6]=> string(0) "" [7]=> string(0) "" } [6]=> array(7) { [1]=> string(0) "" [2]=> string(0) "" [3]=> string(0) "" [4]=> string(0) "" [5]=> string(0) "" [6]=> string(0) "" [7]=> string(0) "" } } ["joursmax"]=> ∫(46) } array(6) { [1]=> array(7) { [1]=> string(0) "" [2]=> int(1) [3]=> int(2) [4]=> int(3) [5]=> int(4) [6]=> int(5) [7]=> int(6) } [2]=> array(7) { [1]=> int(7) [2]=> int(8) [3]=> int(9) [4]=> int(10) [5]=> int(11) [6]=> int(12) [7]=> int(13) } [3]=> array(7) { [1]=> int(14) [2]=> int(15) [3]=> int(16) [4]=> int(17) [5]=> int(18) [6]=> int(19) [7]=> int(20) } [4]=> array(7) { [1]=> int(21) [2]=> int(22) [3]=> int(23) [4]=> int(24) [5]=> int(25) [6]=> int(26) [7]=> int(27) } [5]=> array(7) { [1]=> int(28) [2]=> int(29) [3]=> int(30) [4]=> int(31) [5]=> string(0) "" [6]=> string(0) "" [7]=> string(0) "" } [6]=> array(7) { [1]=> string(0) "" [2]=> string(0) "" [3]=> string(0) "" [4]=> string(0) "" [5]=> string(0) "" [6]=> string(0) "" [7]=> string(0) "" } } int(2) 

I think I'm in deep trouble.

Edit: Well, I did billions of print, changed the name from "jours" to "nbjours" and set my $_SESSION['nbjours']= to my 0 and everything is working, thanks for the help.

(nothing like prints)

I'm going to shamelessly bump this topic, but oh well, it suits me just fine.
So, I have pretty much the same problem, I'm retrieving my variable passed by session (set to 0 some time before, and I increment it each time I visit the page that troubles me), it works perfectly on my local setup, but once online, it messes up.
My variable "jours" does exist though, I've done numerous tests, here is my code

 $travail=$_SESSION['jours']; $travail=($travail+$count); $_SESSION['jours']=$travail;

The message: Fatal error: Unsupported operand types in /homepages/33/d181993762/htdocs/arondor.com/Html/cra/account/docs/cra/cra_multi_print.php on line 40

Line 40 is the second one ^^'

Do you have any idea? Because I'm stuck x_x

Thanks for helping me :3

Indeed, I had forgotten that!
It works now.
Thank you

It's strange, we learn something new every day even when we don't seek information!!!!

Autant pour moi : remet les apostrophes ce code était bon !
J'avais pas lu ton code attentivement mais tu utilises un objet tableau au lieu d'une variable simple dans $compteur ! Pas étonnant que ça plante LOL

Remplace:

$compteur=mysql_fetch_array($result); $nombre=$compteur+1;

Par

$champs=mysql_fetch_array($result); $compteur = $champs['compteur']; // ou $champs[n] avec n correspondant à la position du champ compteur $nombre=$compteur+1;

My field is of type varchar...
is that where the problem comes from?

Hi

Oh, that's weird...

Maybe if your field "compteur" is of numeric type, try removing the quotes

$requete1="UPDATE visites SET compteur=$nombre WHERE compteur=$compteur";

but I hardly believe it...

What is the exact type of your field "compteur"?
