Problème d'enregistrement au format PNG
Bonjour,
Je suis entrain de créer un script pour upload et le redimensionnement d'images:
Avec les fichiers JPG tous ce passe bien, avec les fichiers PNG je n'ai aucun message d'erreur mais le fichiers n'est pas enregistré!
D'avance merci pour vos réponses...(je publie la totalité de mon script il y a un appel a du JS puis le formulaire et la partie PHP désolé pour la longueur...)
JS:
<!--
function uploadInit() {
var oLoading = new Image();
oLoading.src = "loading.gif";
}
function uploadRun() {
document.getElementById("uploadStatus").innerHTML = "<img src=\"/default/images/loading.gif\" alt=\"OK...\" width=\"220\" height=\"19\" />";
document.getElementById("uploadSubmit").disabled = true;
return true;
}
function uploadEnd(sError, sPath) {
if(sError == 'OK') {
document.getElementById("uploadStatus").innerHTML = "<a href=\"" + sPath + "\" title=\"Go to " + sPath + "\">téléchargement réussi!</a>";
} else {
document.getElementById("uploadStatus").innerHTML = sError;
}
document.getElementById("uploadSubmit").disabled = false;
}
//-->
</script>
HTML:
<body onunload="uploadInit();">
<form id="uploadForm" enctype="multipart/form-data" action="test5.php" target="uploadFrame" onsubmit="uploadRun();" method="post" value="2097152">
<p> </p>
<p><input id="uploadFile" name="uploadFile" type="file" />
<input id="uploadSubmit" type="submit" value="télécharger" /></p>
<div align="left" class="vert" id="uploadStatus"></div>
<iframe id="uploadFrame" name="uploadFrame" src="#"></iframe>
</form>
PHP:
if(isset($_FILES['uploadFile']))
{
if ($_FILES['uploadFile']['error'] <= 0)
{
if ($_FILES['uploadFile']['size'] <= 2097152)
{
$filename = $_FILES['uploadFile']['name'];
$path = pathinfo($filename);
$filesext = $path['extension'];
$filesext = strtolower($filesext);
$extensions_autorisees = array('jpg', 'jpeg', 'pjpg', 'pjpeg', 'JPG', 'png', 'gif', 'tiff');
if (in_array($filesext, $extensions_autorisees))
{
$mimeext = array('jpg' => 'image/jpeg', 'jpeg'=>'image/jpeg', 'png'=>'image/png', 'gif'=>'image/gif', 'tiff'=>'image/tiff' );
$mimextie = array('jpg' => 'image/pjpeg', 'jpeg'=>'image/pjpeg');
if ($filesext == 'jpg' || $filesext == 'jpeg' || $filesext == 'pjpg' || $filesext == 'pjpeg')

$jpgimg = getimagesize($_FILES['uploadFile']['tmp_name']);
if($jpgimg['mime'] == $mimeext[$filesext] || $jpgimg['mime'] == $mimeextie[$filesext])
{
}
else

Bonjour, voici la solution:
$errors=null;
/*les tests*/

$path = pathinfo($filename);

$filesext = strtolower($filesext);
$extensions_autorisees = array('jpg','jpeg','pjpg','pjpeg','jpg','png','gif','tiff');
$destpath = './uploads_img/';
if ($_FILES['uploadFile']['error'] <= 0){
}else{
$errors.='Erreur lors de l\'upload image';
exit($errors);
}
if ($_FILES['uploadFile']['size'] <= 2097152){
}else{
$errors.='L\'image est trop lourde';
exit($errors);
}
if(in_array($filesext,$extensions_autorisees)){
}else{
$errors.='Le type MIME de l\'image n\'est pas bon';
exit($errors);
}
$img = @getimagesize($_FILES['uploadFile']['tmp_name']);
if($filesext==='jpg' && ($img['mime']==='image/jpg' || $img['mime']==='image/jpeg' || $img['mime']==='image/pjpeg')){
$jpgimg = imagecreatefromjpeg($_FILES['uploadFile']['tmp_name']);
$tjpgimg = getimagesize($_FILES['uploadFile']['tmp_name']);
$newlarg = 350;
$newhaut = ( ($tjpgimg[1] * (($newlarg)/$tjpgimg[0])) );
$newjpgimg = imagecreatetruecolor($newlarg,$newhaut) or die ("Erreur");
imagecopyresampled($newjpgimg,$jpgimg,0,0,0,0,$newlarg,$newhaut,$tjpgimg[0],$tjpgimg[1]);
imagedestroy($jpgimg);
$filerename = 'fichier_du_'.date('YmdHis').'.'.$filesext;
imagejpeg($newjpgimg ,$destpath.$filerename,100);
}
elseif($filesext==='png' && ($img['mime']==='image/png' || $img['mime']==='image/x-png')){
