複数の画像をサーバーにアップロードし、各画像の異なる解像度バージョンを作成しようとしています。これを行うために、私は初めて class.upload.php を使用しています。http://www.verot.net/php_class_upload.htm
ドキュメントを見て、デモの例から始めます http://www.verot.net/php_class_upload_download_zip.htm
複数入力フォームを作ってみた
<form name="form3" enctype="multipart/form-data" method="post" action="upload.php">
<p><input type="file" size="32" name="my_field[]" value="" /></p>
<p><input type="file" size="32" name="my_field[]" value="" /></p>
<p><input type="file" size="32" name="my_field[]" value="" /></p>
<p><input type="file" size="32" name="my_field[]" value="" /></p>
<p><input type="file" size="32" name="my_field[]" value="" /></p>
<p class="button"><input type="hidden" name="action" value="multiple" />
<input type="submit" name="Submit" value="upload" /></p>
</form>
例の元の php は、サイズを変更せずに画像のみをアップロードします。
$files = array();
foreach ($_FILES['my_field'] as $k => $l) {
foreach ($l as $i => $v) {
if (!array_key_exists($i, $files))
$files[$i] = array();
$files[$i][$k] = $v;
}
}
// now we can loop through $files, and feed each element to the class
foreach ($files as $file) {
// we instanciate the class for each element of $file
$handle = new Upload($file);
// then we check if the file has been uploaded properly
// in its *temporary* location in the server (often, it is /tmp)
if ($handle->uploaded) {
// now, we start the upload 'process'. That is, to copy the uploaded file
// from its temporary location to the wanted location
// It could be something like $handle->Process('/home/www/my_uploads/');
$handle->Process($dir_dest);
// we check if everything went OK
if ($handle->processed) {
// everything was fine !
echo 'ok';
} else {
// one error occured
echo ' Error: ' . $handle->error . '';
}
} else {
// if we're here, the upload file failed for some reasons
// i.e. the server didn't receive the file
echo ' Error: ' . $handle->error . '';
}
}
私がやりたいのは、if ($handle->processed) {} 内の各ファイルを処理することです。そのため、img のサイズを変更して if ($handle->processed) {} 内に貼り付ける例から関数を取り出しました。部。次のようになります。
if ($handle->uploaded) {
// now, we start the upload 'process'. That is, to copy the uploaded file
// from its temporary location to the wanted location
// It could be something like $handle->Process('/home/www/my_uploads/');
// now, we start a serie of processes, with different parameters
// we use a little function TestProcess() to avoid repeting the same code too many times
function TestProcess(&$handle, $title) {
global $dir_pics, $dir_dest;
$handle->Process($dir_dest);
// we check if everything went OK
if ($handle->processed) {
// everything was fine !
echo 'ok';
} else {
// one error occured
echo ' Error: ' . $handle->error . '';
}
}
if (!file_exists($dir_dest)) mkdir($dir_dest);
// ----------- save the uploaded img adding _xl to the name
$handle->file_name_body_add = '_xl';
$handle->file_overwrite = true;
TestProcess($handle, 'File originale', '');
// ----------- save the uploaded img adding _l to the name and downsizing it
$handle->file_name_body_add = '_l';
$handle->image_resize = true;
$handle->image_ratio_y = true;
$handle->image_x = 1024;
$handle->file_overwrite = true;
TestProcess($handle, 'Ridimensionato a 1024px');
}
この時点で、スクリプトは最初の img でのみ正常に動作します。「foreach ($files as $file)」を $files 配列に追加することはできません...エラーの場所を見つけるのを手伝ってもらえますか? ありがとうダニエレ
