Could you help me please? Here is my code at the file leasing.php:

<?php
/* Thanks to Deemru */

require __DIR__ . '/vendor/autoload.php';

$wk = new WavesKit('T');
$wk->setSeed('my seed dream embrace caution accuse panic uncover chicken');

$sleep = 10;

$tx = $wk->txLease($wallet_leasing, $leaseAmount);

$trx = $wk->txTransfer($wk->getAddress($wallet_leasing), $leaseAmount);
$tx = $wk->txBroadcast($tx);

But when I execute from console it's work and successful:

Thank you before for your help.

I tried with the fix #6 , but nothing has change: may I try something else? there's a way to get exactly the answer from Waves? Probably there's something wrong with my code...

Proposal to add a method to retrieve Data by specifying a regexp. The engine should extract all keys satisfying a certain regexp.

There could be a performance problem if the regexp expression extract too many items, maybe a limit can be added.

Alternatively please evaluate an API to extract all data from an address so it can be processed in an array

Hi, I'm using the latest version of the WavesKit, txInvokeScript function in particular.
$wk = new WavesKit( 'T' ); // 'T' for testnet
$wk->setSeed( $user_bc_seed );
$options = array(
"fee" => 900000
);
$args = [
$titolo,
$arrayData
];
$tx = $wk->txSign( $tx );
$tx = $wk->txInvokeScript( $user_bc_address, "addItem", $args, null, $options);
$tx = $wk->txBroadcast( $tx );
$response = json_encode($tx);

$tx before txBroadcast look like
{
"type":16,
"version":1,
"sender":"3MsJAaF5QnFSPWt1FbTYg2rZEYGE89zL9xm",
"senderPublicKey":"AuwNnJne9DDzFJMVzgSTvELEvJKcS6sAwa1pYot7NSZc",
"timestamp":1565976714741,
"dApp":"3MsJAaF5QnFSPWt1FbTYg2rZEYGE89zL9xm",
"call":{
"function":"addItem",
"args":[
{"type":"string","value":"eee"},
{"type":"string","value":"{"titolo":"eee","descrizione":"ytutyuty","allegato":""}"}]
},
"payment":[],
"fee":500000,
"chainId":84
}

The function addItem is a script deployed into dApp and works if called from Waves IDE.
From my php code, I get FALSE as answer but I can't understand what happens.

Someone can help me? Thank in advance

How can I get an address using the phrase seed?

And how can I get the private key using the seed phrase?

Hi, I would like to use the "Update Asset Info Transaction", but when I've tried to compile an asset script with a restriction on it, I've got an error even if the script was correct in waves-ide.com.
Basically I think that it depends on version: is it possible to have this transaction using your library? In the documentation I have not seen this kind of functionality, but... better ask!

Thanks in advance.

I am still not get the date format for waves timestamp more than 10 digits, something like this: 1561174381555 as I know In PHP date format just 10 digits. I have try to use:
date('Y-m-d H:i:s T') but the output: 51441-08-25 05:25:55 WIB
but if I substr 3 digit from behind 1561174381(555) the output: 2019-06-22 10:33:01 WIB
what is the actual date format for waves timestamp?
Thank you.

Hello @deemru I have an issue when implemented txTransfer using bot. When I use the entire parameter no issue found. But when I devide the two parameters ($recipient and $amount) I get an error:

ERROR: https://nodes.wavesplatform.com (1) (failed to parse json message)

notes: $cmd_second = recipient and $cmd_third = amount are the 2 parameters input by user on Telegram bot
/send 3P3gpCLtTJb63Ac94LVoUmFLMQwcyjKbfRW 100

Here is my code:

$wk = new WavesKit('W');
$wk->setPrivateKey('Csv3gBlAblablalallAlbalal');
$assetId = '42LxnagWNNeEvHNk5zhWg6WPPpgYoyxjbSAA8m28MTQb';
$feeAssetId = '8RwwkZJ373Nm6fJCgV2Lefe6FeWawUY2APujcsauUNMR';

$options = ['fee' => 1, 'feeAssetId' => $feeAssetId];
$tx = $wk->txTransfer($cmd_second, $cmd_third, $assetId, $options);
$tx = $wk->txSign($tx);
$tx = $wk->txBroadcast($tx);

if I wrote directly the parameter no error appear:

$tx = $wk->txTransfer(3P3gpCLtTJb63Ac94LVoUmFLMQwcyjKbfRW, 100, $assetId, $options);

Please help me to solve this issue. Thank you.

I installed with composer require deemru/waveskit
And what I get you can see here
I think you need to update package

Hi, I'm trying to use txIssue method in the following way
$wk = new WavesKit( 'T' );
$wk->setSeed( $user_bc_seed );
$confirmations = 1;
$sleep = 10;
$tokenName = $user_bc_alias . '_' . strval($order_id);
$tokenDescription = 'NFT per ' . $titolo;
$tx = $wk->txIssue( $tokenName, $tokenDescription, 1, 0, false );
$tx = $wk->txSign( $tx );
$tx = $wk->txBroadcast( $tx );
$tx = $wk->ensure( $tx, $confirmations, $sleep );
$tokenId = $tx['id'];

the trace for $tx is
{"type":3,"version":2,"sender":"3MsJAaF5QnFSPWt1FbTYg2rZEYGE89zL9xm","senderPublicKey":"AuwNnJne9DDzFJMVzgSTvELEvJKcS6sAwa1pYot7NSZc","fee":100000000,"timestamp":1566380070986,"name":"INARTE_PippoPippo_80557","description":"NFT per Prova LUI","quantity":1,"decimals":0,"reissuable":false}

but I get no answer, neither FALSE nor array.
What can I try?

Thanks in advance

I don't know if I am making some mistakes...

Testing with TESTNET address: 3Mzp4yJ3CGWTX5Wy1f67aLaTvxdCW2ZdyPj, private key: BG3qtTABZnx74zZqMkFs5Q8tusKaCXDefmzLAswK9AzT

        $wk = new deemru\WavesKit( 'T' );

Hi, I would like to add an alias for a NFT created using php script. Is there a way I can follow?
Thanks

Добрый день!
У меня уже подключена support/Keccak.php отдельным пакетом. Вы не сменили namespace в переопределенном классе Keccak.php и теперь возникают ошибкa Cannot declare class kornrunner\Keccak, because the name is already in use

using API /matcher/orderbook/market

https://docs.waves.exchange/en/waves-matcher/matcher-api#place-market-order

Thanks

Thank you for sharing this package.

I can seem to get the txOrder to work.

I most likely have got the sequence for transmitting an order incorrect. Can you point me in the right direction.

`require DIR . '/../vendor/autoload.php';
use deemru\WavesKit;

$wk = new WavesKit();
$wk->setPrivatekey('REDACTED_BUT_CORRECT');
$order = $wk->txOrder ('Ft8X1v1LTa1ABafufpaCWyVj8KkaxUWE6xBhW6sNFJck', 'BiHyoWW3M3AjbU1pE5t1hNrJG5KtmtFvD43UDpqRyyzh', false, 25, 100, 10 * 60 );
$signed = $wk->txSign($order);
$return = $wk->txOrderBroadcast($signed);
var_dump($signed);
var_dump($return);`

Here is the output:

array(13) { ["version"]=> int(2) ["sender"]=> string(35) "3PGmcbDUGaTtxMSv1HsCmVSbAQkj7CagQ3a" ["senderPublicKey"]=> string(43) "8VAwR7Tpd9h189YGJQHJwWFxCGU31qvuZCAbSTY45qb" ["matcherPublicKey"]=> string(44) "7kPFrHDiGw1rCm7LPszuECwWYL3dMf6iMifLRDJQZMzy" ["assetPair"]=> array(2) { ["amountAsset"]=> string(44) "Ft8X1v1LTa1ABafufpaCWyVj8KkaxUWE6xBhW6sNFJck" ["priceAsset"]=> string(44) "BiHyoWW3M3AjbU1pE5t1hNrJG5KtmtFvD43UDpqRyyzh" } ["orderType"]=> string(3) "buy" ["amount"]=> int(25) ["price"]=> int(100) ["matcherFee"]=> int(300000) ["timestamp"]=> int(1559810103668) ["expiration"]=> int(1559810104268) ["id"]=> string(44) "C3kQxnhnbzwJwV5bLjbHMGAnUTP1hdoVhgx7SXASnReA" ["proofs"]=> array(1) { [0]=> string(87) "Nfy7Fqt2B8XiuhHhE4zs8CqhscS3C75vmpkEo4yeMxHru2vdjY5AAMHEXkrpgc3iZh6NfnPwtCQXhe3Wy1Bpbhr" } } bool(false))

Hello sir..
I still confuse how to convert the prices on Waves with PHP. I have use the code like something below:

function convert_price($n)
{
    // first strip any formatting;
    $n = (0 + str_replace(",", "", $n));

    // is this a number?
    if (!is_numeric($n)) return false;
    // now filter it;
    if ($n > 10000000000000) return ($n / pow(10, 21)); //13/21
    elseif ($n > 1000000000000) return ($n / pow(10, 14)); //12/21
    elseif ($n > 100000000000) return ($n / pow(10, 14)); //11/21
    elseif ($n > 10000000000) return ($n / pow(10, 14)); //10/14
    elseif ($n > 1000000000) return ($n / pow(10, 13)); //9/13
    elseif ($n > 100000000) return ($n / pow(10, 13)); //8/13
    elseif ($n > 10000000) return ($n / pow(10, 8)); //7/13
    elseif ($n > 1000000) return ($n / pow(10, 8)); //6/10
    elseif ($n > 100000) return ($n / pow(10, 8)); //5/8
    elseif ($n > 10000) return ($n / pow(10, 8)); //4/8
    elseif ($n > 1000) return ($n / pow(10, 8)); //3/8
    elseif ($n > 100) return ($n / pow(10, 8)); //2/8
    elseif ($n > 10) return ($n / pow(10, 8)); //1/8
    elseif ($n > 0) return ($n / pow(10, 8)); //0/8

    return number_format($n, 8, ',', '.');
}```

but sometimes the formula above works, sometimes the digits numbers of price changes. I found the formula at the matcher.wavesplatform.com something like this:
```10^(8+Asset1desimal - Asset2desimal)```
and another formula with for Python.
But how to implement it to PHP? Thanks before if you kindly to make any function for this issue.
