redimentionnement d'image avec php sous ubuntu

je suis entrai de suivre le cours de php et je suis arriver au redimensionnement des images mais sa ne marche pas et pour savoir je suis sous ubuntu et je suis un debutant en ce qui concerne ubuntu , j'ai installe apache2, php5, mysql separement et je suis entrain de travailler normalement je suis aller sur phpinfo et j'ai trouver GD support enable donc sa veut dire que sa marche mes le redimentionnement d'image ne marche pas par contre sous windows march tre tre bien alr je vous empris aider moi pour que je puisse terminer le cours et avance plus rapidement bye et merci

Si tu veux qu'on t'aide faut nous d'aider un minimum de précision,

->Erreur dans ton fichier log.
->Ligne de l'erreur dans ton fichier php.

Ce sera déjà un bon début :ccool:

J'en connais un qui va encore faire du mal aux chats pour lire dans les entrailles et deviner ton code....

Tu peux regarder içi pour GD GD

je ne sais pas comment vous preciser plus car comme je vous les dit je suis debutant en ubuntu et j'ai installer apache, php, mysql separement, puis vant que je vienne ici je suivi un lien sur le forum d'ubuntu et qu'on ma donner là en dernier mais ca se veux pas marche car quand je veux redimensionner mon image je veux dire par là que la rendre plus petite que l'original et quand j'en registre et bien sa ne marche pas par contre avec win7 a l'aide wamp server sa marceh tres bien

Attend je vais faire un tour de magie 8-).

Tada :P, ah non ça marche toujours pas :calim2:

En gros on peut pas t'aider avec les infos que tu nous donne (parce qu'il y'en a pas). Je suis désolé mais le ça marche pas ne nous aide pas vraiment.

Encore une fois, si tu veux de l'aide dis nous ce qui cloche, et pour ça reporte toi à ton fichier de log. Nous ne somme pas devin, ça marche pas on a compris mais on est pas sur ta machine on ne sais pas ce que tu fais ni comment tu le fais donc des infos des infos et encore des infos (au risque de me répéter).

<?php

// La photo est la source up.png c'est la photo originale et elle se trouve sur le meme dossier que la page
$source = imagecreatefrompng("ub.png");

//destination c'est la mini photo
$destination = imagecreatetruecolor(200, 150); // On crée la miniature vide

// on prend le s dimension de chaqu'une des photos

$largeur_source = imagesx($source);
$hauteur_source = imagesy($source);
$largeur_destination = imagesx($destination);
$hauteur_destination = imagesy($destination);

// On crée la miniature
imagecopyresampled($destination, $source, 0, 0, 0, 0, $largeur_destination, $hauteur_destination, $largeur_source, $hauteur_source);

// On enregistre la miniature sous le nom "mini.png"
imagepng($destination, "mini.png");

?>

ou puis-je trouver le fichier log. ???

Tout d'abord prend l'habitude de mettre tes lignes de code entre les balises code (#) car comme ça on peut avoir la coloration syntaxique. Petite précision, tu rajoute le langage utilisé [CODE =php] ;).

En ce qui concerne ton error_log va dans fichier de configuration httpd.conf apache2.conf sur linux :D (/etc/apache2/apache2.conf) et cherche une ligne qui ressemble à ça :

Code:

---

ErrorLog /var/log/apache2/error.log

---

je crois que c'est le chemin par défaut mais je suis plus sur car je ne dev plus sur linux mais sur mac. (donc tu as maintenant le chemin de ton error_log).

merci cher mathias je tiendrai compte de ces remarque puis voila le contenue de mon fichier apache2.conf

#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "foo.log"
# with ServerRoot set to "/etc/apache2" will be interpreted by the
# server as "/etc/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
LockFile ${APACHE_LOCK_DIR}/accept.lock

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5

#
# DefaultType is the default MIME type the server will use for a document
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value. If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
# It is also possible to omit any default MIME type and let the
# client's browser guess an appropriate action instead. Typically the
# browser will decide based on the file's extension then. In cases
# where no good assumption can be made, letting the default MIME type
# unset is suggested instead of forcing the browser to accept
# incorrect metadata.
#
DefaultType None


#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

# ErrorLog: The location of the error log file.
# If you do not specify an ErrorLog directive within a <VirtualHost>
# container, error messages relating to that virtual host will be
# logged here. If you *do* define an error logfile for a <VirtualHost>
# container, that host's errors will be logged there and not here.
#

#
# LogLevel: Control the number of messages logged to the error_log.
# Possible values include: debug, info, notice, warn, error, crit,

LogLevel warn

# Include module configuration:
Include mods-enabled/*.load

# Include all the user configurations:

#
# The following directives define some format nicknames for use with
# a CustomLog directive (see below).
# If you are behind a reverse proxy, you might want to change %h into %{X-Forwarded-For}i
#

Maintenant que tu as le chemin de ton fichier log, ouvre le et met nous les erreurs qui concerne ta manip de GD.

comment ça je n'ai pas compris svp pouvez vous me donnez un exemple et merci d'avance

Je vais pas m'étendre sur le sujet, le fichier error_log recense toutes les erreurs qui surviennent sur tes scripts PHP.

Donc ce qu'il faudrait faire c'est l'ouvrir et relevé les erreurs, quel point ne comprend tu pas ?

j'ai trouver normalement mais je ne sais pas car j'ai fair bcp de modif leur de mon essye donc voilà et j'espere que sa vous aideras pour me donner la solution et merci

vérifie si tu(en fait le user utilisé par apache) a les droit d'écriture dans le répertoire ou tu sauve l'image

mais comment faire svp preciser impeu avec les commendes aproprié

oui merci c fait merci de votre aide et compréhension les gars

dans ubuntu tu va sur (pas dans) ton dossier qui contient ta page et ton image
click droit / propriété / onglet permission
et pour propriétaire et groupe et autres
tu selectionne
acces au dossier [création et suppression des fichiers]
acces aux fichiers [lecture et écriture]

ensuite tu click sur [appliquer les permissions aux fichiers inclus]
ensuite tu [ferme]

et tu reteste
