Pushover API error sending message in PHP - php

Question

So I'm following the Pushover FAQ example for PHP:
<?php
curl_setopt_array($ch = curl_init(), array(
CURLOPT_URL => "https://api.pushover.net/1/messages.json",
CURLOPT_POSTFIELDS => array(
"token" => "APP_TOKEN",
"user" => "USER_KEY",
"message" => "hello world",
)));
curl_exec($ch);
curl_close($ch);
?>
That example works great, but if I try to send the message as a variable like:
"message" => $variable,
It gives me an error saying that I can't send a blank message.
I guess it's a language related problem. How can I assign a variable to the array "message"?
Thank you.

Answer 1

Maybe there is a problem with Curl, you can use this function to post array data into api.pushover.
function sendApiPushover(){
$url = 'https://api.pushover.net/1/messages.json';
$data = array(
"token" => "APP_TOKEN",
"user" => "USER_KEY",
"title" => "John",
"message" => "hello world"
);
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => http_build_query($data)
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return $result;
}

It seems that your variable $message is empty. Better to check before running this script by:
<?php
if(!empty($message)){
curl_setopt_array($ch = curl_init(), array(
CURLOPT_URL => "https://api.pushover.net/1/messages.json",
CURLOPT_POSTFIELDS => array(
"token" => "APP_TOKEN",
"user" => "USER_KEY",
"message" => $message,
)));
curl_exec($ch);
curl_close($ch);
}
?>
