Question

i need to save in a folder on server pdfs and in a db the relative url.
but with the code that i show you below i get the error in php:"please choose a file"...i don't know why.
I show you my code:
REST CLIENT SIDE:
enter image description here
SERVER SIDE:
<?php
//importing dbDetails file
require_once 'dbDetails.php';
//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;
$upload_url = 'http://'.$server_ip.'/azz/'.$upload_path;
//response array
$response = array();
if($_SERVER['REQUEST_METHOD']=='POST'){
//checking the required parameters from the request
if( isset($_POST['nome_pdf']) && isset($_FILES['pdf']['nome_pdf']) && isset($_POST['id'])){
//connecting to the database
$con = mysqli_connect(DB_HOST,DB_USERNAME,DB_PASSWORD,DB_NAME) or die('Unable to Connect...');
//getting name from the request
$nome = $_POST['nome_pdf'];
//getting file info from the request
$fileinfo = pathinfo($_FILES['pdf']['nome_pdf']);
//getting the file extension
$extension = $fileinfo['extension'];
$id = $_POST['id'];
//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['pdf']['tmp_name'],$file_path);
$sql = "INSERT INTO `my_db`.`pdfss` (`id_pdf`, `nome_pdf`, `url_pdf`,`id_user`) VALUES (NULL, '$nome','$file_url', '$id');";
//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['nome_pdf'] = $nome;
$response['url_pdf'] = $file_url;
}
//if some error occurred
}catch(Exception $e){
$response['error']=true;
$response['message']=$e->getMessage();
}
//closing the connection
mysqli_close($con);
}else{
$response['error']=true;
$response['message']='Please choose a file';
}
//displaying the response
echo json_encode($response);
}
I hope that you can help me!

Answer 1

This line
if( isset($_POST['nome_pdf']) && isset($_FILES['pdf']['nome_pdf']) && isset($_POST['id'])){
Should be
if( isset($_POST['nome_pdf']) && isset($_FILES['nome_pdf']['tmp_name']) && isset($_POST['id'])){
Or
if( isset($_POST['nome_pdf']) && isset($_FILES['nome_pdf']['name']) && isset($_POST['id'])){

Answer 2

Your error comes from here
isset($_FILES['pdf']['nome_pdf'])
NOTE: You do not use $_POST when dealing with file uploads in PHP. Use $_FILES. I think you are confused with the name of the file and also the array_keys that are associated with the $_FILES array
nome_pdf is not in the $_FILES array. If you try a dump of var_dump($_FILES['pdf']);, you will see that nome_pdf is not in the array.
Replace the line with:
if( isset($_FILES['pdf']) && $_FILES['pdf']['tmp_name'] != '' && isset($_POST['id'])){
#add your code
else{
$response['error']=true;
$response['message']= 'PDF FILE: '. $_FILES['pdf'].' ID of post: '.$_POST['id'];
exit;
}
echo(json_encode($reponse));
The above change will make sure the tmp_name is not empty.
Also before moving the file, i suggest using mime type to check for the extensions
