How to attach files to Atlassian Confluence page using PHP - php

Question

I'm working on attaching files via PHP to confluence (version 5.9.10)
Here is my code
$ch=curl_init();
$headers = array(
'X-Atlassian-Token: no-check'
);
$data = array('file' => '#test.txt');
curl_setopt_array(
$ch,
array(
CURLOPT_URL=>'https://<path_to_confluence>/rest/api/content/<page_id>/child/attachment',
CURLOPT_POST=>true,
CURLOPT_VERBOSE=>1,
CURLOPT_POSTFIELDS=>$data,
CURLOPT_SSL_VERIFYHOST=> 0,
CURLOPT_SSL_VERIFYPEER=> 0,
CURLOPT_RETURNTRANSFER=>true,
CURLOPT_HEADER=>false,
CURLOPT_HTTPHEADER=> $headers,
CURLOPT_USERPWD=>C_USERNAME.":".C_PASSWORD
)
);
$result=curl_exec($ch);
$ch_error = curl_error($ch);
if ($ch_error) {
echo "cURL Error: $ch_error";
} else {
var_dump($result);
}
curl_close($ch);
But after running script I've next error:
>

What I'm doing wrong? What have I missed?

Answer 1

Try this:
$data = array('file' => '#' . realpath('test.txt'));
...
CURLOPT_POSTFIELDS=>$data
If the filename is required, you can try this instead:
$data = array('file' => '#' . realpath('test.txt') . ';filename=test.txt'));
...
CURLOPT_POSTFIELDS=>$data

Answer 2

I encountered this error when I was using the lib cURL and was doing it the old way, like:
CURLOPT_POSTFIELDS => [
'file' => '#/pathToFile'
]
But since it's deprecated from PHP 5.5, you need to use it the new way:
Imperative way:
CURLOPT_POSTFIELDS => [
'file' => curl_file_create($filePath)
]
Object way:
CURLOPT_POSTFIELDS => [
'file' => new CurlFile($filePath)
]
