I would like to add the Apartment Number optional field at checkout (without third-party plugins) so it will be added automatically at the New Customer Order email and PDF invoice that is automatically generated.

I am getting error from IE when I redirect to “dashboard” controller after settings session values in “login” function ( return redirect()->to(base_url('dashboard'));). I have this working on Chrome, Firefox, Edge, and Opera.

I am using public $sessionDriver = 'CodeIgniterSessionHandlersDatabaseHandler'; for session storage. this works well with other borwsers.

I am trying to figure out what the best/most efficient way to get individual /24 IP blocks from a range of IP addresses using PHP.

I have ranges of IP addresses in an MySQL database (I cannot change how this is presented) and have to have individual ranges of /24 blocks saved, also in a specific way (I cannot change the MySQL entries, nor how the software processes the list).

For example, I have various ranges of IPv4 IP addresses in this format:

86.111.160.0 - 86.111.175.255

Which I need to save in this format:

86.111.160.0
86.111.161.0
86.111.162.0
...
86.111.175.0

I’m having a bit of a block on how to do this without writing something hugely complicated to process each line.

Is there any function in PHP that can help me with this?

Thanks in advance.

I’ve been having this issue lately.

So basically I have a string that I get like this:

$contents = file_get_contents("system.po");

And it looks like this:

msgctxt "views.view.fra_vacancies:label:display:default:display_title:display_options:exposed_form:options:submit_button:reset_button_label:exposed_sorts_label"
msgid "Sort by"
msgstr ""

msgctxt "views.view.fra_vacancies:label:display:default:display_title:display_options:exposed_form:options:submit_button:reset_button_label:exposed_sorts_label:sort_asc_label"
msgid "Asc"
msgstr ""

(but with many entries like the above)

And I also have a table like this called $finalArray (with many entries as well):

[1041] => Array
        (
            [0] => Sort by name
            [1] => Ταξινόμηση κατά όνομα
        )
[1042] => Array
        (
            [0] => Country
            [1] => Χώρα
        )

What I do is going to each msgid in my file-string with strpos and check the value (for example “Sort By”), then i search if the value exists in my table (at [0] index) and then I move to msgstr with strpos and I replace the whole line with a string which contains the translation from my table (at [1] index)

Here is the code:

$lastPos = 0;
//while loop to go to each 'msgid' in my file-string
while (($lastPos = strpos($contents, 'msgid', $lastPos))!== false) {
//here i get the whole 'msgid' line
  $startOfLine = strrpos($contents, "n", ($lastPos - $len));
  $endOfLine = strpos($contents, "n", $lastPos);
  $sourceLine = substr($contents, $startOfLine, ($endOfLine - $startOfLine));

//here i change the pos and i go to the next 'msgstr' and i get the whole line
  $lastPos = strpos($contents, 'msgstr', $lastPos);
  $start = strrpos($contents, "n", ($lastPos - $len));
  $end = strpos($contents, "n", $lastPos);
  $transLine = substr($contents, $start, ($end - $start));

//here i find the value that matches from my array and i try to replace the substring
  foreach ($finalarray as $key => $value) {
    if (substr_count_array($sourceLine, [$value[0], 'msgid']) == 2){
      $rstring = 'msgstr ' . '"' . $value[1] . '"';
//debugged and checked that $sourceLine and $transLine are correct but is the issue * 
      $contents = substr_replace($contents, $rstring, $start, 0);
      break;
    }
  }
}
//just a function that checks if more strings exist in a substring
function substr_count_array( $haystack, $needle ) {
  $count = 0;
  foreach ($needle as $substring) {
       $count += substr_count( $haystack, $substring);
  }
  return $count;
}

*The issues is that when i use:

$contents = substr_replace($contents, $rstring, $start, 0);

I get an infininte loop and when I assing the result of substr_replace to a different variable (for example $contentsNew) and I echo it, my strings aren’t replaced.

Thank you for your time.

I’m trying to generate a regular expression to detect any string that :

• Starts with the [
• Ends with ]
• Contains any word or number or space

Example : [Maxsens8 Innovations]

I’m using : https://regex101.com

I create this regular expression : ^[[a-zA-Z0-9]]$

This regular expression does not match to expressions that i’m looking for and i thing the problem

is about the last character .

I will be gratefull if someone explain to me how to generate to right regular expression that

detect strings like : [Maxsens Innovations] [Verifik8] [Divoluci] …

I’m not a Laravel/PHP dev. Just trying to setup a service built in it..

Have setup APP_URL to a scheme & domain-name based url. And the views are generating links using route(..) function.
But, the links that are getting generate have Base URL at which it is browsed instead of APP_URL config.

For example:

If http://abc.domain, https://abc.domain and https://a12.domain all are endpoint of same app. And we have config for APP_URL=https://abc.domain.
Still depending on what we use to browse the page as; if visited via https://a12.domain.. it will generate route with https://a12.domain at base.

ASSET_URL are working. APP_URL is not having any impact though.

Versions in use are

  "laravel/framework": "^8.12",
  "laravel/helpers": "^1.4",
  "laravel/tinker": "^2.5",

I have created a query in SQL and it works quite well.

SELECT learning_content_number,
            course,
            count(required) as required,
            count(overdue) as overdue,
            count(status) as status,
            count(completion_date) as completion_date

            FROM hse_leatros
            GROUP BY learning_content_number 

Now I want to translate it in Laravel 8 Eloquent. This script works, but I am missing the information about the course.

$courses = Leatro::groupBy('learning_content_number')
        ->selectRaw('count(required) as required, learning_content_number')
        ->selectRaw('count(overdue) as overdue, learning_content_number')
        ->selectRaw('count(status) as status, learning_content_number')
        ->selectRaw('count(completion_date) as completion_date, learning_content_number')
        ->get();

How can I enter the in the code that it is transferred with?

I’m struggling to show the different shipping classes on the product page in Woocommerce. I have found several codes that show the shipping class of simple products. But not codes that show the classes of the different variations on a variable product.

The code should get the shipping class of simple products to show (cause I gave several simple products). But when the product is a variable product it needs to show the shipping classes of the variations instead of the parent shipping class.

I am not capable of coding this, hoping there is someone who is skilled enough and willing to help.

It would be nice if the front end looks like this:
Front end shipping class

I have a php script that perform some actions after killing some old processes.

act.php

$pids = shell_exec('ps aux | grep "saso" | awk '{print $2}'');
$pids = str_replace("n", ' ', $pids);
$pids = array_filter(explode(' ', $pids));

foreach ($pids as $pid) {
    shell_exec('kill -9 ' . $pid . ' > /dev/null 2>&1 &');
}

// reset of the code . ..

The script works well by running php act.php. It fetch process ids, kill it, then run the reset.

But it is not working when I run nohup php act.php & or nohup php act.php. The process is not killed.

I need nohup to run the script in the background with no hang up.

Can’t PHP script fetch pids behind nohup ? and are there any alternatives ?

Thanks in advance.

In a Symfony5 application, how can we utilize the form-component to correctly set up a self-referencing, many-to-many relationship?

Note: this is purely about the form-side of things, Doctrine is already happy.

Let’s say we have a “Person”-entity, and these Person-instances host guests, who are also Persons:

#[Entity(repositoryClass: PersonRepository::class)]
class Person
{
    #[Id]
    #[GeneratedValue]
    #[Column(type: Types::INTEGER)]
    private int $id;

    #[Column(type: Types::STRING, length: 255)]
    private string $firstName;

    #[Column(type: Types::STRING, length: 255)]
    private string $lastName;

    /** @var Collection<Person> */
    #[ManyToMany(targetEntity: self::class, inversedBy: 'guestsHosted')]
    private Collection $hosts;

    /** @var Collection<Person> */
    #[ManyToMany(targetEntity: self::class, mappedBy: 'hosts')]
    private Collection $guestsHosted;

    public function __construct()
    {
        $this->fellowshipHosts = new ArrayCollection();
        $this->fellowsHosted = new ArrayCollection();
    }

    // getters/setters ommitted for brevity


    public function addHost(self $host): self
    {
    }

    public function removeHost(self $host): self
    {
    }

    public function addGuestsHosted(self $guestHosted): self
    {
    }

    public function removeGuestsHosted(self $guestsHosted): self
    {
    }

What I would like to achieve is a form with a collection of addable/removable rows, where the user then is able to add a row, select an existing other person as their host, add another row, select another person, and so on. A simple mockup:

How do I achieve this using Symfony’s form-component? What I have in there now does not work due to recursion on the same form-type:

class PersonType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options): void
    {
        $builder           
            ->add('firstName', null, [])
            ->add('lastName', null, [])            
            ->add('hosts', CollectionType::class, [
                'entry_type' => self::class,
                'entry_options' => ['label' => false],
                'required' => false,
                'allow_delete' => true,
                'allow_add' => true,
                'by_reference' => false,
            ]);
    }

    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => Person::class,
        ]);
    }
}

NB: I’ve built similar UIs like this in the past and know about the little dance involving form.vars.prototype and hooking up the JS to that. Where I’m lost is how to map this association on the form-level, so that I get a dropdown of all Persons, and map that into the $hosts property of the entity.

Any help is appreciated!

I am currently creating a Symfony Project for School and i was just trying some things out with this Security Bundle… I was creating the Registration Controller with this php bin/console make:registration-form Command and it worked out fine. The Files got created and i got no Errors but when i am trying to go to /register they just show me my index.php all the time… if i delete index.php its always # Page not Found from my Symfony Local Server… Im just testing out so im just using this localhost Webserver from Symfony. I tested out the Route with php bin/console router:match /register and it showed green, it works and exists. But when i try going to the Site nothing happens.
