[Mod] detecter URL image et affichage

Wan · 20-03-2012 10:45:30

D'autre part, j'ai trouvé le pourquoi de l'affichage multiple, et là c'est de ma faute, j'ai oublié un WHERE dans ma requête dans le plugin.
Donc dans AP_Forums_last_images.php, il faut remplacer la ligne :

$result = $db->query('SELECT f.id, f.forum_name, f.last_img, f.last_img_dsp FROM '.$db->prefix.'forums AS f INNER JOIN '.$db->prefix.'categories AS c ORDER BY c.disp_position, c.id, f.disp_position') or error('Unable to fetch category/forum list', __FILE__, __LINE__, $db->error());

par :

$result = $db->query('SELECT f.id, f.forum_name, f.last_img, f.last_img_dsp FROM '.$db->prefix.'forums AS f INNER JOIN '.$db->prefix.'categories AS c WHERE f.cat_id=c.id ORDER BY c.disp_position, c.id, f.disp_position') or error('Unable to fetch category/forum list', __FILE__, __LINE__, $db->error());

Bonjour,

Dis-moi déjà avec ça si tu n'as plus d'erreur "Unable to update".

Bah du coup j'ai une nouvelle erreur

La ligne en question : (l'une des lignes que tu ma dit de changer)

$db->query('UPDATE '.$db->prefix.'forums SET num_topics='.$num_topics.', num_posts='.$num_posts.', num_replies='.$num_replies.', last_post='.$last_post.', last_post_id='.$last_post_id.', last_poster=\''.$db->escape($last_poster).'\', last_img='.(is_null($last_img) ?

WHERE id='.$forum_id) or error('Unable to update last_post/last_post_id/last_poster', __FILE__, __LINE__, $db->error());

Je cherche l'erreur en question en m'aidant des autre topic sur ce forum. Si vous savez je suis preneur. smile

Du coup pour l'affichage multiple je n'ai pas pu verifier vu que j'ai cette erreur ! sad

Essaye de mettre en mode "Show Queries" pour afficher les requêtes qui sont effectuées sur ta BDD pendant l'exécution.
Pour cela, à la fin de ton config.php, rajoute :

define('PUN_SHOW_QUERIES', 1);

Ensuite tu vas jusqu'au moment où l'erreur se produit et tu nous montre la liste des requêtes.

a-snowboard · 20-03-2012 19:26:05

En fait l'erreur se fait d'entré de jeux sur l'index. et je suis dans l'impossibilité d'aller nulle part...

je regarde comment je fait pour trouver la liste des requêtes. Et oui patience je ne connais pas tout ! siffle

a-snowboard · 20-03-2012 21:01:28

je crois savoir comment afficher la liste de requête. mais pas pour une page précise.

Mais pour le coup je suis pas sur.

Otomatic a écrit :

Bonjour,
Tant pour les champs des tables de BDD que pour les variables PHP, NULL ne répond correctement à aucune condition, sauf :
IS NULL ou IS NOT NULL pour les champs des tables
is_null(...) Indique si une variable vaut NULL pour les variables PHP
isset(...) Détermine si une variable PHP est définie et est différente de NULL
Tout autre condition de test sur NULL engendre un résultat indéterminé
Il y a une seule valeur de type null, et c'est la constante insensible à la casse NULL. Ce qui veut dire que 'NULL' (Constante NULL entre quote) est considéré comme une chaîne dont le contenu est la suite de caractères N U L L.
La valeur spéciale NULL représente une variable sans valeur. NULL est la seule valeur possible du type NULL.
Une variable est considérée comme null si :
elle s'est vue assigner la constante NULL.
elle n'a pas encore reçu de valeur.
elle a été effacée avec la fonction unset().

Bonjour Otomatic.
En décriptant le code de parser.php j'ai trouvé ça (ligne 85) :

	if ($temp === null)

Et encore pire (ligne 678) :

	if ($alt == null)

Cela ne correspond pas à tes préconisations. Qu'en penses-tu ?

Bonjour,

Je vais faire un rapport de bug.
La comparaison avec l'opérateur de comparaison "===" est bonne. Ce type de comparaison permet de vérifier l'égalité ET le type. (http://www.php.net/manual/fr/language.o … arison.php)

C'est l'opérateur à utiliser pour vérifier, par exemple, que le résultat d'une fonction est bien false et non pas une valeur similaire à false, comme 0 (zéro).

Wan · 21-03-2012 20:15:47

Bon, du coup et pour résumer, les deux seuls tests valables d'une variable $variable à NULL (ou non) sont donc :
soit :
if (is_null($variable)) (ou if (!is_null($variable)))
soit :
if ($variable === NULL) (ou if ($variable !== NULL))

Du coup, tu vas pouvoir "gonfler" ton rapport de bug sur le code source de FluxBB 1.4.8 :

- dans functions.php :
ligne 968: if($date_format == null)
ligne 971: if($time_format == null)
ligne 1178: if ($key == null)

- dans moderate.php :
ligne 878: if ($cur_topic['moved_to'] == null)

- dans viewforum.php :
ligne 172: if ($cur_topic['moved_to'] == null)
ligne 201: if (!$pun_user['is_guest'] (...) && $cur_topic['moved_to'] == null)
ligne 248: <td class="tc2"><?php echo ($cur_topic['moved_to'] == null) ? (...)
ligne 249: <?php if ($pun_config['o_topic_views'] == '1'): ?> (...) <?php echo ($cur_topic['moved_to'] == null) ? (...)

- dans include/parser.php (déjà cité) :
ligne 678: if ($alt == null)

- dans include/dblayer/mysql.php :
ligne 324: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)
ligne 338: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)

- dans include/dblayer/mysqli.php :
ligne 331: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)
ligne 345: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)

- dans include/dblayer/mysql_innodb.php :
ligne 338: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)
ligne 352: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)

- dans include/dblayer/mysqli_innodb.php :
ligne 344: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)
ligne 358: return $this->query('ALTER TABLE ' (...) ($after_field != null ? ' AFTER '.$after_field (...)

Voilà, j'espère ne rien avoir oublié... hmm

[EDIT] J'ai finalement "gonflé" moi-même dans le ticket #642 du .org partie development/core : https://fluxbb.org/development/core/tickets/642/

heu...
je suis un peut perdu avec mon show query là... si vous avez un lien
qui m'explique comment extraire les requêtes...
car je suis completzment paumé la.

mais apres ce n'est pas une fonction prioritaire.
c'sst surtout l'affichage en baniere qui me sera beaucoup plus utile.

bon apres j'ai pas tout suivit ce probleme de bug... desole je suis a la deche ! sad

Otomatic · 22-03-2012 11:55:11

Bonjour,

Dans le fichier config.php, tu ajoutes (Ou décommente) la ligne :

define('PUN_SHOW_QUERIES', 1);

À partir de là, toutes les requêtes seront affichées en bas des pages du forum, avec leur durée d'exécution et le contenu complet de chaque requête.
Ne pas oublier de commenter la ligne après utilisation

Wan · 22-03-2012 12:24:28

Quand tu ajoutes à la fin de ton config.php :

define('PUN_SHOW_QUERIES', 1);

cela permet d'afficher les requêtes effectuées au bas de chaque page, dans un block titré "Informations de débogage".
Evidemment, si la page d'erreur s'affiche immédiatement, ces informations ne s'affichent pas.
Mais on peut peut-être avoir quand même des informations utiles en mode "Debug".
Pour cela, à la fin de ton config.php ajoute :

define('PUN_DEBUG', 1);

Va ensuite sur ton index qui pose problème et rapporte-nous le message qui s'affiche.

a-snowboard a écrit :

Pour cela tu peux essayer ceci :

Editer index.php et trouver :

require PUN_ROOT.'header.php';

Ajouter après :

// Display last posted images
$nb_img = 7;
$result = $db->query('SELECT p.id, p.message FROM '.$db->prefix.'posts AS p INNER JOIN '.$db->prefix.'topics AS t ON t.id=p.topic_id INNER JOIN '.$db->prefix.'forums AS f ON f.id=t.forum_id WHERE t.moved_to IS NULL AND f.last_img_dsp=1 ORDER BY p.posted DESC') or error('Unable to fetch message from posts', __FILE__, __LINE__, $db->error());
?>
<div id="lpi" class="blocktable">
	<h2><span><?php echo 'Dernières images postées' ?></span></h2>
	<div class="box">
		<div class="inbox">
			<table cellspacing="0">
				<tr>
<?php
$i = 0;
while ($tracked_post = $db->fetch_assoc($result))
{
	$list_img = detect_image($tracked_post['message']);
	if ($list_img[0] > 0)
 	{
		for ($j = $list_img[0] ; $j > 0; $j--)
			{
				$i += 1;
?>
				<th style="text-align:center"><a href="viewtopic.php?pid=<?php echo $tracked_post['id'].'#p'.$tracked_post['id'] ?>"><img src="<?php echo $list_img[$j] ?>" height="100" alt="" /></a></th>
<?php
				if ($i == $nb_img)
					break 2;
			}
	}
}					
?>					
				</tr>
			</table>
		</div>
	</div>
</div>
<?php

Envoyer sur le serveur.

Désolé pour ce hors-sujet. Il s'agissait de rectifier quelques erreurs dans le code de FluxBB concernant les tests de variables avec la valeur NULL dont le type est particulier.

Bonjour,

Et oui, une digression, mais profitable à tous. De plus : « bug » fixé : Setting all null-checks to use is_null().

a-snowboard · 22-03-2012 17:32:40

bon manière d'avoir un peut l'impression d'avancer j'ai mis le code pour l'index. ça marche sans problème. smile

J'ai juste une modification a faire pour que ce soit compatible avec fluxrewite. car le bête copiage de code ne marche pas sad (ça aurais été trop beau !)

Pour mon erreur initiale je fait ça dès que je peux ! smile
Bon après vu qu'il y a conflit avec une mod existante je ne sais pas si ça vaut le coup de batailler. Je vais quand même essayer ! smile

Bon j'ai suivit les instructions en ce qui concerne les requêtes.
Donc pour récapituler avec le nouveau code proposé par wan (voir ci dessus) :
J'ai un plantage dès l'index. impossibilité d’accéder nulle par. Je n'ai pu avoir aucune indication en ce qui concerne les requêtes. Mod débug ou pas.

Du coup j'ai remis le code initial (donc avant modification proposé par wan)
Voila ce qu'il en sort :

Bonjour,

num_replies=rien du tout, last_topic_id=rien_du_tout. Si les deux colonnes n'acceptent pas les NULL, il y a erreur.

a-snowboard · 22-03-2012 18:44:04

Bonsoir

Bon je sais que je deviens petit à petit l'homme à abattre sur ce sujet. Mais a force de faire des essais (vive le ctrl+z) et que ce n'est pas concluant je me tourne vers vous

En fait sur l'image suivante le problème est visible :
la phrase "Dernières images postées par les membres" est au même niveau que les images.

En fait le top serait d'avoir "Dernières images postées par les membres" de la même configuration que "derniers message"
et que les images s'affichent sur un fond blanc juste en dessous (sans l’icône carré bien entendu !)

Pour le moment a part ajouter </ br></ br> je n'ai rien trouvé de mieux, et c'est moche au possible ! sad

Merci d'avance

Ps : désolé j'ai oublié d'enlever firebug sur l'image.

fichier 2 : Concerne le problème d'affichage des images devant chaque forum sur l'index. en clair le mod qu'a fait wan et que j'ai adapté en fonction de mon code. Au risque de me répéter ce problème là est vraiment secondaire pour moi car j'ai plus une préférence pour l'affichage en bannière que devant chaque forum.

Après analyse de tes deux fichiers include/functions.php, il manque des modifs (ou peut-être ont-elles disparues lors de tes manips), d'où les dysfonctionnements.
Bon, procédons par ordre chronologique des modifs proposées, et commençons donc par ton fichier 2 :

Ligne 718, tu as :

	$result = $db->query('SELECT last_post, last_post_id, last_poster, subject, id, num_replies FROM '.$db->prefix.'topics WHERE forum_id='.$forum_id.' AND moved_to IS NULL ORDER BY last_post DESC LIMIT 1') or error('Unable to fetch last_post/last_post_id/last_poster', __FILE__, __LINE__, $db->error());

et il faut avoir :

	$result = $db->query('SELECT t.last_post, t.last_post_id, t.last_poster, t.subject, t.id, t.num_replies, p.message, f.last_img FROM '.$db->prefix.'topics AS t INNER JOIN '.$db->prefix.'posts AS p ON p.id=t.last_post_id INNER JOIN '.$db->prefix.'forums AS f ON f.id='.$forum_id.' WHERE t.forum_id='.$forum_id.' AND t.moved_to IS NULL ORDER BY t.last_post DESC LIMIT 1') or error('Unable to fetch last_post/last_post_id/last_poster', __FILE__, __LINE__, $db->error());

Concernant ton fichier 1, à la ligne 722, tu as :

		list($last_post, $last_post_id, $last_poster, $last_topic, $last_topic_id, $num_replies) = $db->fetch_row($result);

et il faut avoir :

		list($last_post, $last_post_id, $last_poster, $last_msg, $last_topic, $last_topic_id, $num_replies) = $db->fetch_row($result);

Maintenant, si tu veux que ta bannière fonctionne, il faut prendre comme base ton fichier 2 avec la modif de la ligne 718 correctement appliquée. Le fichier 1 est trop incomplet pour espérer quoi que ce soit.
