[`eth.getTransaction("{txhash}")`](https://github.com/ethereum/wiki/wiki/JavaScript-API#web3ethgettransaction) and [`eth.getTransactionReceipt("{txhash}")`](https://github.com/ethereum/wiki/wiki/JavaScript-API#web3ethgettransactionreceipt) will provide you with the details.

The `.blockNumber` field will be `null` until the transaction is included into a mined block.

Following are some examples of using `eth.getTransaction(...)` and `eth.getTransactionReceipt(...)` to find out the transaction status.

## Pending Transaction, Not Mined Into Blockchain At Time Of Query

Here's the output when there are no pending transactions

    // eth.getBlock("pending").transactions[0] = null
    > eth.getTransaction(eth.getBlock("pending").transactions[0])
    invalid or missing value for params[0]
        at web3.js:3119:20
        at web3.js:6023:15
        at web3.js:4995:36
        at <anonymous>:1:1

And here's a pending transaction. `.blockNumber = null`.

    > eth.getTransaction(eth.getBlock("pending").transactions[0])
    {
      blockHash: "0x0000000000000000000000000000000000000000000000000000000000000000",

## Transaction Mined Successfully, But Contract Execution Failed

Here is an [example](http://etherscan.io/tx/0x93f39d4213bc48d9e6adda181ddd468d18163ae894ffc3f1a81d34ea33629f84) of a transaction that was successfully mined into the blockchain, but the contract execution failed.

In this case `gas(50878) == gasUsed(50878)`. 

This occurs because the Smart Contract code called by the transaction detected an error and threw an exception and this consumes ALL gas.

See http://ethereum.stackexchange.com/questions/2307/why-does-a-solidity-throw-consume-all-gas for more information about the throwing of errors and gas usage.

And note that there could possibly be the case where a Smart Contract executes without any errors and consumes EXACTLY the same amount of gas as specified with the sent transaction details.

## Regular Transaction That Fails, Does Not Get Mined Into The Blockchain

I'm sending more ethers than is available in my account. The error is caught before the transaction is mined into the blockchain.
