How to upload files with POST form-data in PHP? - php

Question

The normal curl way, works well.
curl \
-F "smfile=#test.png" \
-H "Content-Type: multipart/form-data" \
https://sm.ms/api/v2/upload
But in my PHP version curl, it returns bool(false) and string(0) "":
<?php
$url = "https://sm.ms/api/v2/upload";
$headers = array();
array_push($headers, "Content-Type: multipart/form-data");
array_push($headers, "User-Agent: ".$_SERVER['HTTP_USER_AGENT']);
// $fields = array('smfile' => curl_file_create('test.png', 'image/png', 'test.png'));
$fields = array('smfile' => new CURLFile('test.png', 'image/png', 'tset.png'));
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
var_dump(curl_exec($ch));
var_dump(curl_error($ch));
What's wrong with my code? ヽ(*。>Д<)o゜

Answer 1

Try this one:
<?php
$url = "https://sm.ms/api/v2/upload";
// I guess the file is in the same directory as this script
$file = __DIR__.'/test.png';
$headers = [
'Content-Type: multipart/form-data',
'User-Agent: '.$_SERVER['HTTP_USER_AGENT'],
];
$fields = [
'smfile' => new CURLFile($file, 'image/png')
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
var_dump(curl_exec($ch));
var_dump(curl_error($ch));
?>

you can use this simple code to upload files
$explode = explode('.', $_FILES['file']['name']);
$ext = $explode[count($explode) - 1];
if(is_uploaded_file($_FILES['file']['tmp_name']))
{
$result = move_uploaded_file($_FILES['file']['tmp_name'],
'uploads/'.basename($_FILES['file']['name']));
echo $result === true ? 'File uploaded successfuly' : 'There are some errors';
}
else
{
echo 'No File uploaded';
}
