Probléme pagination

Par TheDarkNight17, il y a 13 ans


Bonjour, je suis a la partie un du tuto pour creer un blog et comme beaucoup de gens je bloque a la pagination..? Alors voila d'un cotés je met ça (PostsController) :

<?Php
class PostsController extends AppController{
var $name='Posts';
public $paginate = array(
'Post' => array(
'limit' => 1,
'order' => array(
'Post.date' => 'Desc'
)
));
function index(){
$q = $this->paginate('Post');
$this->set('articles',$q);
}
}
?>

Et dans l'autre (index.ctp):

<?php 
echo $this->Paginator->numbers();
debug($articles);
?>

Et il me met ça :

Fatal error: Class 'String' not found in C:\wamp\www\my_blog\lib\Cake\View\Helper\JsHelper.php on line 422

Désolé pour ça j ai sans le faire exprès appuyer sur enter :/

Des idées ? merci d'avance

Je suis pas persuadé que le script de pagination te renvoi l'erreur pour du JS et encore moins avec une class string qui n'apparait nul part !
Edit: tu as un bouton d'édition en haut à droite dans ton post pour éditer le message, et mettre le code en balise.

Pense à entourer ton code de la balise code "<>".
Sinon, essaye de faire juste:

$q = $this->paginate()

si non je sais pas

Voici un fonction paginate très simple coté controller :

public function index() {
        $this->Post->contain('Tag');
        $this->paginate = array(
            'limit' => 10,
            'order' => array('Post.created' => 'desc')
        );
        $data = $this->paginate('Post');
        $this->set('articles',$data);
    }

Et coté view pour afficher la pagination :

<?php echo $this->Paginator->numbers(array(
    'separator' => '-'
)); ?>

bonjour, Merci mais rien ne fonctionne il me met ça maintenant :

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'contain' at line 1

est-ce bien contain qui ce met la ?

Si tu n'as pas de tags associés à ta table Post c'est tout à fait normal ! Enlève cette ligne :

$this->Post->contain('Tag');

Bonjour, de nouveau le problème avec le "STRING" pourtant j'ai tout mis comme tu la mis :? voila mon fichier PostController.php et t-il bon ?

<?Php class PostsController extends AppController{
    var $name='Posts';
    public function index() {
        $this->paginate = array(
        'limit' => 1,
        'order' => array('Post.created' => 'desc')
    );
    $data = $this->paginate('Post');
    $this->set('articles',$data);
    }
    }
?>

A oui et quand je suis sur la page:2 (url) il me met l'erreur mais ci j'actualise plusieurs foie il me remet la page mais en me gardant au dessus cette erreur la :

Strict (2048): Declaration of JsHelper::value() should be compatible with Helper::value($options = Array, $field = NULL, $key = 'value') [CORE\Cake\View\Helper\JsHelper.php, line 422]
Digikube, il y a 13 ans

Voici ce que tu devrais avoir dans ta fonction index (erreur de parenthèse) :

public function index() {
        $this->paginate = array(
            'limit' => 1,
            'order' => array('Post.created' => 'desc')
        );
        $data = $this->paginate('Post');
        $this->set('articles',$data);
    }

Peux tu mettre le code de ta view index aussi stp car le JsHelper rien a voir avec ton controller.

Non ça ne change rien toujours la même erreur

Digikube, il y a 13 ans

Quel est l'erreur exactement ? Et avec le code de ta view ca serait le top :)
