Bulletproof is a single-class PHP library to upload images securely.
Install using git
$ git clone https://github.com/samayo/bulletproof.gitInstall using Composer
$ composer require samayo/bulletproof:5.0.*Or download it manually in a ZIP format
To quickly upload images, use the following HTML & PHP code:
<form method="POST" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="1000000"/>
<input type="file" name="pictures" accept="image/*"/>
<input type="submit" value="upload"/>
</form>require_once "path/to/bulletproof.php";
$image = new Bulletproof\Image($_FILES);
if($image["pictures"]){
$upload = $image->upload();
if($upload){
echo $upload->getPath(); // uploads/cat.gif
}else{
echo $image->getError();
}
}For more options or configurations, check the following examples:
Methods to set restriction on the image name, size, type, etc.. to upload
// To provide a name for the image. If unused, image name will be auto-generated.
$image->setName($name);
// To set the min/max image size to upload (in bytes)
$image->setSize($min, $max);
// To define a list of allowed image types to upload
$image->setMime(array('jpeg', 'gif'));
// To set the max image height/width to upload (limit in pixels)
$image->setDimension($width, $height);
// To create a folder name to store the uploaded image, with optional chmod permission
$image->setStorage($folderName, $optionalPermission);Methods to retrieve image data before/after upload.
// To get the image name
$image->getName();
// To get the image size (in bytes)
$image->getSize();
// To get the image mime (extension)
$image->getMime();
// To get the image width in pixels
$image->getWidth();
// To get the image height in pixels
$image->getHeight();
// To get image location (folder where images are uploaded)
$image->getStorage();
// To get the full image path. ex 'images/logo.jpg'
$image->getPath();
// To get the json format value of all the above information
$image->getJson();How to use the property setters and getters.
$image = new Bulletproof\Image($_FILES);
$image->setName("samayo")
->setMime(["gif"])
->setStorage(__DIR__ . "/avatars");
if($image["pictures"]){
if($image->upload()){
echo $image->getName(); // samayo
echo $image->getMime(); // gif
echo $image->getStorage(); // avatars
echo $image->getPath(); // avatars/samayo.gif
}
}To crop, resize or watermak images, use functions stored in src/utils
Use php exceptions to define custom error responses
if($image['pictures']){
try {
if($image->getMime() !== 'png'){
throw new \Exception('Only PNG image types are allowed');
}
// check size, width, height...
if(!$image->upload()){
throw new \Exception($image->getError());
} else {
echo $image->getPath();
}
} catch (\Exception $e){
echo "Error " . $e->getMessage();
}
}- Uses
exif_imagetype()to get the true image mime (.extension) - Uses
getimagesize()to check if image has a valid height / width in pixels. - Sanitized images names, strict folder permissions and more...
