getting username from form and search in github api - php

Question

I'm trying to search a user using the Github api, but I'm not sure what I'm doing wrong here.
My html form:
<form action="" method="get">
<div class="form-group">
<label >Buscar Usuario</label>
<input class="form-control" type="text" name="username">
</div>
<button type="submit" name="submit" class="btn btn-default">Procurar</button>
</form>
My php code:
<?php
function buscaUser()
{
$user= $_GET['username'];
$ch = curl_init();
$url ="https://api.github.com/search/users?q=".$user;
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
var_dump(json_decode($result));
}
?>

Answer 1

YOu didn't call the buscaUser() anywhere
Do it this way:
<?php
function buscaUser($user) {
$ch = curl_init();
$url ="https://api.github.com/search/users?q=".$user;
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
var_dump(json_decode($result));
}
?>
Then you can call the function and pass the submitted value:
<?php
echo buscaUser($_GET['username']);
?>
Should do!
