[Match Two Types of Strings]

Hi All,

I am terrible at regex.

I have the following code, which works fine for number such as 123456M...

if(!preg_match('/[1-9]\d{5}M/', $explode[1])) {
	throw new RuntimeException('Error: Membership number invalid. Please try again.');
}

However, I also need to accept number such as TMP1 and TMP1000 - essentially TMP followed by up to 5 numbers...

How would I add this too...

I need it to error if it doesn't match any of the two types.

Thanks

[mySQL Structure for Encrypted Data]

Hey,

I am developing an small app that will add data to a mySQL database. This is working fine however, I need to encrypt the data. I have the code to do this; however, I am not sure how people structure the mySQL tables for this?

Obviously, something like varchar(255) might not be long enough. So do you set all columns to be TEXT?

Is there a better way of doing this?

Thanks
Dan

[Up to 6 Numbers followed by a letter]

Hi,

I have the following expression but it doesn't work as I wish it to...

[1-9]\d{5}M

I need any 6 numbers followed by an M.... however, it can be any 5 numbers followed by an M... for example

123456M = Valid
1234M = Valid

But...
123445 = Invalid
RANDOM = Invalid

Thanks

[PhpSpreadsheet - Add Workbook Password]

https://github.com/nick322/secure-spreadsheet adding this repo works.

[PhpSpreadsheet - Add Workbook Password]

Looks like PhpSpreadsheet can't actually protect the opening of a document... see https://github.com/PHPOffice/PhpSpreadsheet/issues/761

Which is odd because to me the documentation reads like it does...

[PhpSpreadsheet - Add Workbook Password]

I tried adding that code but it still doesn't seem to password protect the actual document...

Just unable to edit a sheet or cell...

$security = $spreadsheet->getSecurity();
$security->setLockWindows(true);
$security->setLockStructure(true);
$security->setWorkbookPassword("PhpSpreadsheet");

 

[PhpSpreadsheet - Add Workbook Password]

Hey,

I have the following script that looks to make an excel document using PHPSpreadsheet... the script works great, but it doesn't apply the password to the workbook... what am I missing?

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
// Information
$arrayData[] = array('cells');

// Make File Name
$filename = 'file-'.time().'.xlsx';

$spreadsheet = new Spreadsheet();

$spreadsheet->getActiveSheet()->getProtection()->setSheet(true);
$security = $spreadsheet->getSecurity();
$security->setLockWindows(true);
$security->setLockStructure(true);
$security->setWorkbookPassword("PhpSpreadsheet");

$sheet = $spreadsheet->getActiveSheet();
$sheet->setCellValue('A1', 'Report Generated '. date(DATE_FORMAT_LONG));
$sheet->fromArray($arrayData, NULL, 'A3');

header('Content-Disposition: attachment;filename='.$filename);

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
$writer->save('php://output');

Thanks

[jQuery html() not outputting line breaks]

Hey,

I have the following jQuery line... it gets the object noteInfo and displays it into a modal. Works great! However, it doesn't seem to output the line breaks, I just get a big chunk of text. Any ideas would be amazing.

jQuery Line

$("#viewNoteModal .modal-body").html(obj.noteInfo);

Console output

noteInfo: "This is a note\r↵Sent: 26 September 2022 12:56"

Dan

 

EDIT - I have worked this out. It was a bug in the code that outputted the text.

[Throttling a script]

sleep() , perchance to dream.

Thanks, I was thinking sleep but I've had problems with that in the past...

20 hours ago, mac_gyver said:

at one per second, it will take 25 minutes to send all the emails. php scripts are not intended to run continuously. you would need to call set_time_limit(...) inside the loop to keep the script from fatally timing out and halting, but not using set_time_limit(0) so as to not prevent the script from stopping due to a programming mistake.

this is normally done by queuing, in a database table, all the mail addresses to be sent to. having a cron job/scheduled task that runs at some reasonable interval, such as once a minute. the code that the cron job triggers checks if the queue has any unsent messages in it, loops, with a sleep() call inside the loop, to send fewer emails than the time to the next execution of the cron job, to prevent overlap, and marks each email in the queue as having been sent. e.g. with the datetime when it was sent.

doing this, you would send ~50 email per minute, in 30 executions of the cron job.

Hmmm I think this might be the way forward... I shall do it like this

1 message per second is what they give you in the sandbox. If you're using this for real messages then you should not be in the sandbox...

Ahh yes, they gave me something like 150,000 emails per day, however, my access keys were leaked and used to send 50,000 odd emails.... so I asked them to move my limit down to 5000 per day as I would never send over that so if it ever happened again I would get stung...

[Throttling a script]

Hey!

I am trying to write a script that will send emails to users using Amazon SES, I have a send limit of 1 per second...

Currently I have 1500 records... how would I throttle the script to only send 1 email per second?

Currently, I just use a foreach loop to go through an array and send the email using that...

$allActiveMembers = $this->getAllMembers('1');
foreach($allActiveMembers as $member){
	// If email blank... skip.
	if($member['memberEmail'] == NULL){
		continue;
	}

    // Email Valid.
	if($this->helper->isValidEmail($member['memberEmail']) == false){
    	continue;
    }

    // Send Email
    $this->SendMail($member['memberEmail']);

}

Thanks

[PHP 8.1 Showing Warnings]

Hey!

I updated my server from PHP 7.4 to PHP 8.1... I have several website on the server and all are now showing some sort of error or another... Most of the errors are warnings such as:

Quote

Warning: Attempt to read property "current" on bool in /www/wwwroot/site.com/wp-admin/update-core.php on line 41

I have changed the php.ini file for 8.1 to exclude warnings bit it doesn't seem to do anything...

Any idea how to stop them from coming up without having to add

error_reporting(E_ALL & ~E_WARNING & ~E_NOTICE);

 to every website...,

Thanks

[Credentials Security]

18 hours ago, kicken said:

Try browsing directly to your .env file on your website, for example http://example.com/.env and see if the file contents comes up.  If it does, then that's your problem.

Ideally you'd store your .env file outside of your webroot so it's inaccessible via any URL.  If you're hosting provider does not allow for that, then you need to configure the webserver to not allow access to your .env file via .htaccess or some similar mechanism.  If you can't do that, then the next best option is to store the credentials as PHP code in a .php file so even if someone does try and load the URL they won't see the PHP code.

 

Thanks so much! I never thought of this bit that indeed was the problem... an oversight I think!!

I have now secured it with htaccess so its Forbidden now.

Thanks for your help!

[Credentials Security]

I have a php application I made…

Currently I use phpdotenv https://github.com/vlucas/phpdotenv to store my creds in a .env file in the root directory…

It works, however twice now the AWS SES creds have been stolen and used to send mass emails…

Im not sure how they’re finding the information but they are… so I’m just trying to figure out how to store them better to avoid them getting into the wrong hands…

[Credentials Security]

Hey,

What is the best way to hide / protect credentials for use in scripts?

For example, where would you store database login details, Amazon AWS logins etc so its secure and hidden away from eyes...

Thanks

So for years I used to use Dreamweaver, then about 5 years ago changed to Coda for MacOS and only 2 years ago changed to Atom by GitHub and absolutely love Atom. However, they announced from 15 December 2022 that they would be closing down Atom... sad I know

[I can't get the right result]

Try this...

<?php
//It's a simple program to valid age but it only print 'you can vote' despite any value I input.
if($_POST['age']){
  $age = int $_POST['age'];

  if($age >= 18){
    echo "you can vote!!!";
  }elseif($age < 18){
    echo "You are not allowed to vote";
  }else{
    echo "enter a valid age";
  }
}
?>

 

Also on your form use this instead... it means the user can only put a number in...

<input type="number" name="age">

There is probably a much easier way to achieve what I am after so any help would be appreciated.

Basically the data is from an external source, so I need to loop through the new data from excel. 

If they are NOT already in the database add them, if they are in the database but cancelled, reactive them and anyone who's in the database but NOT on the excel sheet will be cancelled.

Thanks

[Code Logic - Importer]

Hey!

I am writing a script however, I am a little stuck with the logic for import... here is the background...

I have a database of users, some are active some are inactive.

I have a new array to import, however, in this array people could be one of the following:

New User - Add to database
New User with Existing Account - Rejoin them
Left User - User ID not found in the new array so assume they have left...

I need to process the data and output the following;

Number of New Users
Number of Users Rejoined
Number of Users Left
List of New User IDs
List of Left User IDs
List of Rejoined User IDs

I have written a script, however it doesn't work well and gives me random information that doesn't match so the logic is off somewhere.. can someone help with the logic

Currently it does the following:

1. Counts the current users who are marked as inactive
2. Makes an array of those users
3. Sets all database users to inactive
4. Loops though each new user from import array
5. If user ID exists... update the user to active again
6. If user ID doesn't exist... add them to the database and add new user ID to new array
7. Counts all users who are marked as inactive after import
8. Use array_diff_key to check the difference between inactive array 1 (before import) and array 2 (after import)
9. Counts number of array items for joiners, and leavers...

I hope this makes at least some sense... any help would be appreciated.

Thanks

[Subtract 1 gives minus number]

Hey!

I have the following code in a class..

public function deductCredit(){
		$currentAmount = $this->getCredits();
		$newAmount = $currentAmount - '1';
		$this->dashboard->updateSettings("email_credit", array("count"=>$newAmount));
		return $newAmount;
  }

This gets the current credits... deducts 1 and pushes the update back...

If I run the function outside of the class it works as expected... however, if I run it within a functions a bit further down the class it always returns -1...

Any ideas would be appreciated!
