Problem using hashid.id library

Question

I’m trying to implement the library hashids in my project, I am not using the composer

My job is as simple as that:

function generate_hash_id($id){
    require("../libs/Hashids.php");
    $hashids = new Hashids\Hashids('teste');
    $hash = $hashids->encrypt($id);
    return $hash;
}

But it’s coming back 500 Internal Server Error

I call the function inside an iterator

for($i = 0; $i < 10, $i++){
    generate_hash_id($i);
}

The structure of my project:

From what I understand you’re accusing that the library is not in this path, but that’s the way!

Following the @Uilherme tips, I removed the require from within the function.

require("../libs/Hashids.php");

function generate_hash_id($id){
    $hashids = new Hashids\Hashids('teste');
    $hash = $hashids->encrypt($id);
    return $hash;
}

for($i = 0; $i < 10, $i++){
    generate_hash_id($i);
}

Now the error that returns:

Fatal error: Uncaught Error: Call to Undefined method Hashids Hashids::Encrypt() in /usr/share/Nginx/www/api/Automatic/index.php:16 Stack trace: #0 /usr/share/Nginx/www/api/Automatic/index.php(110): generate_hash_id(1) #1 {main} thrown in /usr/share/Nginx/www/api/Automatic/index.php on line 16

Answer 1

When you call more than once the require it will cause some exception error because the function has already been declared the first time it called the require '../libs/Hashids.php';, if you call again (in your case the loop) it will try to declare again and this is where the error occurs.

As you must be with the errors turned off appears 500 Internal error server, to fix trade require by require_once, something else the method $hashids->encrypt does not exist, the correct is $hashids->encode, see: https://github.com/ivanakimov/hashids.php/blob/master/lib/Hashids/Hashids.php#L114

The correct code would be:

function generate_hash_id($id){
    require_once "../libs/Hashids.php";
    $hashids = new Hashids\Hashids('teste');
    $hash = $hashids->encode($id);
    return $hash;
}
