I’ve a unsigned transaction hex. Now I need to signal this transaction enter with my personal key in PHP utilizing the BitWasp Library. I’ve adopted among the examples and searched the boards and can’t get my head round it.

I get the uncooked transaction from the https://counterparty.io/docs/api/

I get the error Invalid script Signature – Should be push solely.

My Uncooked Unsigned TX:

010000000147e4efecb198d013f9a938904d560d4c831cb3e7ae84cf899c10c5689ed0c2ed000000001976a91409c4d51c89d31a374706ae80249bb408f02b86ba88acffffffff0200000000000000002a6a2846e58e6bfb7a15bc6cd36b7e545f4c86b49ea57539d2b77b57a822a3ac811d7d6846e3416cccc4c673600000000000001976a91409c4d51c89d31a374706ae80249bb408f02b86ba88ac00000000

My code :

    <?php

require_once __DIR__ . "/vendor/autoload.php";

$community = Bitcoin::getNetwork();
$ecAdapter = Bitcoin::getEcAdapter();

$addrCreator = new AddressCreator();
$privFactory = new PrivateKeyFactory($ecAdapter);

$priv = $privFactory->fromWif('MY-PRIVATE-KEY');


$txHex = '010000000147e4efecb198d013f9a938904d560d4c831cb3e7ae84cf899c10c5689ed0c2ed000000001976a91409c4d51c89d31a374706ae80249bb408f02b86ba88acffffffff0200000000000000002a6a2846e58e6bfb7a15bc6cd36b7e545f4c86b49ea57539d2b77b57a822a3ac811d7d6846e3416cccc4c673600000000000001976a91409c4d51c89d31a374706ae80249bb408f02b86ba88ac00000000';
$myTx = TransactionFactory::fromHex($txHex);

$transactionOutputs = [];
foreach ($myTx->getInputs() as $idx => $enter) {
    $transactionOutput = new TransactionOutput(0, ScriptFactory::fromHex($input->getScript()->getBuffer()->getHex()));
    array_push($transactionOutputs, $transactionOutput);
}


$signer = new Signer($myTx, $ecAdapter);

foreach ($transactionOutputs as $idx => $transactionOutput) {
    $signer->signal($idx, $priv, $transactionOutput);
}

$signed = $signer->get();
echo $signed->getHex() . PHP_EOL;

Please can somebody clarify what it’s im doing fallacious and clarify it in layman phrases?
