Bonjour!
J'utilise la class adodb_pager de adodb .
Suite à une requete , j'arrive à afficher mon tableau avec la pagination.tout marche .
Problème!
J'aimerai modifier le code de la class adodb_pager ci-dessous de manière à rajouter une colonne supplementaire(Action par exemple) pour mettre en
face de chaque ligne un bouton radio permettant le choix de la ligne. Je n'arrive pas !
Si quelqu'u à une idée. Merci d'avance
class ADODB_Pager {
var $id; // unique id for pager (defaults to 'adodb')
var $db; // ADODB connection object
var $sql; // sql used
var $rs; // recordset generated
var $curr_page; // current page number before Render() called, calculated in constructor
var $rows; // number of rows per page
var $linksPerPage=10; // number of links per page in navigation bar
var $showPageLinks;
var $gridAttributes = 'width=100% border=1 bgcolor=white';
// Localize text strings here
var $first = '<code>|<</code>';
var $prev = '<code><<</code>';
