我尝试过:
I don't how to upload image in database through PHP and get response in json code.
I am using Postman for run that code
What I have tried:
<?php
//importing dbDetails file
define('HOST','localhost');
define('USER','root');
define('PASS','');
define('DB','db_images');
//this is our upload folder
$upload_path = 'uploads/';
//Getting the server ip
$server_ip = gethostbyname(gethostname());
//creating the upload url
$upload_url = 'http://'.$server_ip.'/AndroidImageUpload/'.$upload_path;
//response array
$response = array();
if($_SERVER['REQUEST_METHOD']=='POST'){
//checking the required parameters from the request
if(isset($_POST['name']) and isset($_FILES['image']['name'])){
//connecting to the database
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect...');
//getting name from the request
$name = $_POST['name'];
$mobile = $_POST['mobile'];
$uid = $_POST['uid'];
$point = $_POST['point'];
//getting file info from the request
$fileinfo = pathinfo($_FILES['image']['name']);
//getting the file extension
$extension = $fileinfo['extension'];
//file url to store in the database
$file_url = $upload_url . getFileName() . '.' . $extension;
//file path to upload in the server
$file_path = $upload_path . getFileName() . '.'. $extension;
//trying to save the file in the directory
try{
//saving the file
move_uploaded_file($_FILES['image']['tmp_name'],$file_path);
$sql = "INSERT INTO `db_images`.`images` (`id`, `url`, `name`,`mobile`, `uid`, `point`) VALUES (NULL, '$file_url', '$name', '$mobile', '$uid', '500');";
//adding the path and name to database
if(mysqli_query($con,$sql)){
//filling response array with values
$response['error'] = false;
$response['url'] = $file_url;
$response['name'] = $name;
$response['uid'] = $uid;
$response['mobile'] = $mobile;
$response['point'] = '500';
}
//if some error occurred
}catch(Exception $e){
$response['error']=true;
$response['message']=$e->getMessage();
}
//displaying the response
echo json_encode($response);
//closing the connection
mysqli_close($con);
}else{
$response['error']=true;
$response['message']='Please choose a file';
}
}
/*
We are generating the file name
so this method will return a file name for the image to be upload
*/
function getFileName(){
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect...');
$sql = "SELECT max(id) as id FROM images";
$result = mysqli_fetch_array(mysqli_query($con,$sql));
mysqli_close($con);
if($result['id']==null)
return 1;
else
return ++$result['id'];
}
?>
推荐答案
upload_path ='uploads /';
//获取服务器ip
upload_path = 'uploads/'; //Getting the server ip
server_ip = gethostbyname(gethostname());
//创建上传网址
server_ip = gethostbyname(gethostname()); //creating the upload url
upload_url ='http://'。
upload_url = 'http://'.
