unsure how or why my lockunspent method is not working...

[nravanelli]

I have been trying for days, and I cannot seem to understand why the EasyBitcoin.php will not accept my parameters for locking unspent transactions using the rpc calls. Here is the code I am using;

$tx = $bitcoin->masternode('outputs');
$txid = array_keys($tx);
$tx_array = [];
	foreach($txid as $locktx) {
          $tx_array = [
                'txid'  => $locktx,
                'vout'  => (int)$tx[$locktx],
            ];
    $lock = "false";
		$lock_mn = $bitcoin->lockunspent($lock, $tx_array);
}

And no matter how I spin it, I keep getting errors like this:

Expected type bool, got string

Has anyone had any success with this rpc command?

$lock = "false";

Have you tried changing this to

$lock = false;

?

@erikdubbelboer yep .... I get this instead;

Expected type array, got object

and here is the var_dump of the txid and vout I am using;

Array
(
    [txid] => 14acd0774013685a4cda17246298f21101884f6be7198db36fa5e3ee498fab37
    [vout] => 1
)

Try this:

$tx = $bitcoin->masternode('outputs');
$txid = array_keys($tx);
$tx_array = [];
foreach($txid as $locktx) {
  $tx_array[] = [
    'txid' => $locktx,
    'vout' => (int)$tx[$locktx],
  ];
}
$lock = "false";
$lock_mn = $bitcoin->lockunspent($lock, $tx_array);

some issue @erikdubbelboer ; I get this:

Expected type bool, got string

And my array changed slightly;

Array
(
    [0] => Array
        (
            [txid] => 14acd0774013685a4cda17246298f21101884f6be7198db36fa5e3ee498fab37
            [vout] => 1
        )

)

Solved!!

$tx = $bitcoin->masternode('outputs');
$txid = array_keys($tx);
$tx_array = [];
foreach($txid as $locktx) {
  $tx_array[] = [
    'txid' => $locktx,
    'vout' => (int)$tx[$locktx],
  ];
}
$lock = false;
$lock_mn = $bitcoin->lockunspent($lock, $tx_array);

I was missing the [] after $tx_array in my first comment. I last too many hours on a simple mistake
thanks for the help @erikdubbelboer !

lockunspent expects an array of objects, you were only giving it one object because you had your call inside your loop instead of out of it.
