PHP 图像另存为对话框

发布于 2024-12-26 05:39:35 字数 519 浏览 1 评论 0原文

我想在单击图像时打开保存图像对话框。我设法打开相同的图像，但保存时，它不会保存打开的已保存图像，因为图像的内容未以某种方式保存。

PHP 代码：

$imageName = $_GET['i'];
$imageName = $imageName . '-HR.jpg';
header ("Content-Type: application/download");
header ("Content-Disposition: attachment; filename=$imageName");
header("Content-Length: " . filesize("$imageName"));
$fp = fopen("$imageName", "r");
fpassthru($fp);

传递的 URL 类似于： mydomain/download_image.php?c=atherothrombosis&i=embolus-carotid-artery-illustration

请建议解决方案。谢谢。

I wanted to open a save image dialog box when I click on an image. I managed to open the same but when saved, it does not save open saved image as the content of image is not saved somehow.

PHP code:

$imageName = $_GET['i'];
$imageName = $imageName . '-HR.jpg';
header ("Content-Type: application/download");
header ("Content-Disposition: attachment; filename=$imageName");
header("Content-Length: " . filesize("$imageName"));
$fp = fopen("$imageName", "r");
fpassthru($fp);

The passing URL is something like:
mydomain/download_image.php?c=atherothrombosis&i=embolus-carotid-artery-illustration

Please suggest solution. Thanks.

还添加此标头

header("Content-Type: application/force-download");

我设法使用下面的代码来做到这一点：

<?php 
$imageName = $_GET['i'];$imageName = $imageName . '-HR.jpg';
$imageCatName = $_GET['c'];
$imageCatName  = ucwords($imageCatName);
$file_path = $docRoot . '/static/media/images/content/image_library/'.$imageCatName . '/'. $imageName;
if(file_exists($file_path)) {
header("Content-disposition: attachment; filename={$imageName}");
header('Content-type: application/octet-stream'); 
readfile($file_path); 
}else {
echo "Sorry, the file does not exist!";
}
?>

仍然非常感谢您的支持。 :)

I managed to do so by using below code:

<?php 
$imageName = $_GET['i'];$imageName = $imageName . '-HR.jpg';
$imageCatName = $_GET['c'];
$imageCatName  = ucwords($imageCatName);
$file_path = $docRoot . '/static/media/images/content/image_library/'.$imageCatName . '/'. $imageName;
if(file_exists($file_path)) {
header("Content-disposition: attachment; filename={$imageName}");
header('Content-type: application/octet-stream'); 
readfile($file_path); 
}else {
echo "Sorry, the file does not exist!";
}
?>

still thanks a lot for your support. :)
