I tried to apply none.PNG if input file empty and i use statement like this. I need to fix this to use it in my systems. thank you.
if(empty($image)){
$name = md5(time() . rand(0, 999)) . '.jpeg';
}else{
$name = 'none.jpeg';
}
public function saveimage()
{
if (isset($_POST['image_loc'])) {
$image = $_FILES['image_loc'];
$allowed = array('image/jpeg', 'image/jpg', 'image/png');
// print_r($image);
// die();
// check for erros
if ($image['error'] != 0) {
die('File upload error: ' . $image['error']);
}
// check if is image
if (in_array($image['type'], $allowed)) {
$name = md5(time() . rand(0, 999)) . '.jpeg';
move_uploaded_file($image['tmp_name'], ROOT . '/public/img/pics/' . $name);
echo $image['tmp_name'];
$this->insert($name);
}
}
}
After edited the code The result show only if I upload file. i need none.PNG as well to show if not upload file. how can i do this.
public function saveimage()
{
if (isset($_POST['image_loc'])) {
$image = $_FILES['image_loc'];
$allowed = array('image/jpeg', 'image/jpg', 'image/png');
// print_r($image);
// die();
// check if is image
if (in_array($image['type'], $allowed)) {
////////////////////////// here ///////////////////////
if (empty($image)) {
$name = md5(time() . rand(0, 999)) . '.jpeg';
} else {
$name = 'none.jpeg';
}
////////////////////////// here ///////////////////////
move_uploaded_file($image['tmp_name'], ROOT . '/public/img/pics/' . $name);
echo $image['tmp_name'];
$this->insert($name);
}
}
}
If $_POST["image_loc"]
is remote url, you can use function below that returns file size. So can check if it returns 0 or not. If $_POST["image_loc"]
isn't remote url and it's image path in your server, you can simply use filesize($image_path)
function to get image size.
function get_image_size($image_url){
$ch = curl_init($image_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE);
$data = curl_exec($ch);
$size = curl_getinfo($ch, CURLINFO_CONTENT_LENGTH_DOWNLOAD);
curl_close($ch);
return $size;
}
