Extraction d'un fichier Excel Entre deux dates (Date debut et Date fin)

Version imprimable

bonjour ,
je fais l'exportation d'un fichier excel contenant tous les donnés enregistrés dans la base, au niveau de mon interface j'affiche liste des donnés entre deux dates, je veux faire même chose pour le fichier excel qu'il n'affiche que les donnés entre deux dates .

J'ai pas réussi à faire ceci pendant l'extraction: je vous communique le code de la fonction d'affiche et puis le code de la fonction d'extraction .

Code:

 function FindDisqueDate($d_debut,$d_fin) {
        $cnx = new Connection();
        try {
            $sql = "SELECT * FROM disque WHERE D_T BETWEEN '$d_debut' And '$d_fin'  ";
            return $cnx->getDB()->query($sql)->fetchAll(2);
        } catch (PDOException $e) {
            echo $e->getMessage() . "<br>";
            echo "la requete n'est pas valide";
            exit;
        } 
    }

 function generatecsv(){
	$this->layout = 'layout';
		$this->loadModel('disque');
		$dis = new Disque();
		$disque = $dis->OutCSV();//$d_debut,$d_fin);
		echo json_encode(0);
		exit;
	}

ici c'est le code de la fonction d'exportation :

Bonjour, as-tu fait un print_r sur $data pour voir si ta requête sort bien agencée dans le tableau?
C'est un peu bourrin d'utiliser un array_unshift avec deux tableaux en arguments, me semble-t-il.
De plus tu veux surement ajouter les éléments de data en début de $rowrn donc il faut faire autrement.

Sinon je ne vois aucune référence à $data par la suite dans les fonctions de mise en forme du xlsx, ça ne me parait pas normal...

php excel te génère-t-il un fichier xlsx aux normes?

si c'est bien le cas, je ne sais pas d'où ça vient, sinon vérifie le header php que tu fais, il n'est peut-être plus correct.

Erreur Excel

voilà mon code est là : j'arrive ni à afficher les légendes ni à résoudre le probléme montré

pourquoi trois fois save?
tu bourres le tampon de php avec deux saves successifs, puis tu génères un fichier sur disque.

comprends pas, seul un save suffit à priori...

Avec ce code essaie de charger un xlsx depuis le disque:
Code:

1 2 3 4 5 6 7 8 9 $file = "myfile.xlsx" ; header('Content-Disposition: attachment; filename=' . $file ); header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); header('Content-Length: ' . filesize($file)); header('Content-Transfer-Encoding: binary'); header('Cache-Control: must-revalidate'); header('Pragma: public'); readfile('myfile.xlsx');
si ça marche, essaie de reproduire ce code dans ton fichier php après avoir fait un save sur le disque, un petit usleep pour laisser le temps au systême de fichiers de le prendre en compte et le read de ce code fonctionnera.
