QUESTION
Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events). But they don't get fulfilled when I make them from my react app (see react app contract's etherscan events https://kovan.etherscan.io/address/0x6da2256a13fd36a884eb14185e756e89ffa695f8#events).
Same contracts (different addresses), same function call.

Here's the code I use to call them in my tests

Hello my favorite people!
I am trying to send an email after submitting a form, with the AUTO INCREMENT number attached to the email because the AUTO INCREMENT number is the clients Job Card Reference Number. So far i have successfully created the insert script which inserts the data into the database perfectly, and also sends the email too. But does not attach the AUTO INCREMENT number into the email. The INT(11) AUTO INCREMENT primary key is "job_number" in my MySQL database.
Here is my insert page:

QUESTION
I have this code I have entered into Remix IDE, as ReceivedEther.sol, a standalone smart contract.
I've transferred 0.02 Ether to the smart contract, using MetaMask.
When I checked the smart contract's balance, it returns 200000000000000000, as expected.
If I try to use the transferEther function, however, and enter a number smaller than this - say, 0.005 ETH, or 50000000000000000 as the amount - it doesn't work using MetaMask.
When MetaMask prompts me it's never for that amount. It's for 0 ETH and 0.00322 gas fee (or whatever the gas is). Basically it always set the amount of ETH at 0 and only charges the fee.
Why can't I transfer an amount of ETH using this function in the Remix IDE with MetaMask?
...ANSWER
Answered 2021-Jun-13 at 21:44Your code sends ETH (stated in the _amount variable) from the smart contract to the _recipient. So it doesn't require any ETH to be sent in order to execute the transferEther() function.
If you want your contract to accept ETH, the function that accepts it (or the general fallback() or receive() function) needs to be marked as payable.
Example:

QUESTION
I'm using an API that returns § characters with a color code (1-9 or a-h) which I want to eliminate (§ and following character). Their purpose is for color formatting but I'm not using that and my method iterates through a string to remove them but could not find a better way and it fees too hacky and buggy. Is there like a parameter for the str.replace function that removes the letter after the found character?
ANSWER
Answered 2021-Jun-12 at 02:35You can "eliminate" the precise pattern with regular expressions using the sub method:

Answered 2021-Jun-10 at 17:06You should change the is_active field to boolean.
Join the student table with student_session.student_id = students.student_id, and filter by the is_active field in student_session

It looks like this:
...ANSWER
Answered 2021-Jun-10 at 18:36I may have made this too complicated, but wasn't sure how else to approach it. This will
- first create a
rangesarray with start, end and amount usingreduce mapthe persons array, iterating throughrangesto get the amount due from that range (if any)- get the total duration, in milliseconds, convert to a rough approximation of number of months, then round down using a modulus.
In the end you get a new persons array (npersons) with the total due in it.
