さて、画像をトリミングして表示するこのコードがあります。表示するだけでなく、画像をフォルダに保存したかったのは完全なコードです
<?php

define('DESIRED_IMAGE_WIDTH', 512);
define('DESIRED_IMAGE_HEIGHT', 289);
$source_path = $_FILES['Image1']['tmp_name'];
/*
* Add file validation code here
*/
list($source_width, $source_height, $source_type) = getimagesize($source_path);
switch ($source_type) {
case IMAGETYPE_GIF:
$source_gdim = imagecreatefromgif($source_path);
break;
case IMAGETYPE_JPEG:
$source_gdim = imagecreatefromjpeg($source_path);
break;
case IMAGETYPE_PNG:
$source_gdim = imagecreatefrompng($source_path);
break;
}
$source_aspect_ratio = $source_width / $source_height;
$desired_aspect_ratio = DESIRED_IMAGE_WIDTH / DESIRED_IMAGE_HEIGHT;
if ($source_aspect_ratio > $desired_aspect_ratio) {
/*
* Triggered when source image is wider
*/
$temp_height = DESIRED_IMAGE_HEIGHT;
$temp_width = ( int ) (DESIRED_IMAGE_HEIGHT * $source_aspect_ratio);
} else {
/*
* Triggered otherwise (i.e. source image is similar or taller)
*/
$temp_width = DESIRED_IMAGE_WIDTH;
$temp_height = ( int ) (DESIRED_IMAGE_WIDTH / $source_aspect_ratio);
}
/*
* Resize the image into a temporary GD image
*/
$temp_gdim = imagecreatetruecolor($temp_width, $temp_height);
imagecopyresampled(
$temp_gdim,
$source_gdim,
0, 0,
0, 0,
$temp_width, $temp_height,
$source_width, $source_height
);
/*
* Copy cropped region from temporary image into the desired GD image
*/
$x0 = ($temp_width - DESIRED_IMAGE_WIDTH) / 2;
$y0 = ($temp_height - DESIRED_IMAGE_HEIGHT) / 2;
$desired_gdim = imagecreatetruecolor(DESIRED_IMAGE_WIDTH, DESIRED_IMAGE_HEIGHT);
imagecopy(
$desired_gdim,
$temp_gdim,
0, 0,
$x0, $y0,
DESIRED_IMAGE_WIDTH, DESIRED_IMAGE_HEIGHT
);
/*
* Render the image
* Alternatively, you can save the image in file-system or database
*/
header('Content-type: image/jpeg');
imagejpeg( $desired_gdim );
/*
* Add clean-up code here
*/
?>
imagejpeg( $desired_gdim );
私の問題は、あるべき最後の行にありますimagejpeg( $desired_gdim, 'img/whatever-filename.jpg' );
しかし、画像はブラウザにも表示されず、ディレクトリにも送信されません。また、ファイル名で挿入したい場合は、既にアップロードした同じことが壊れた画像の小さなアイコンで発生します
