PHP - Adding A Link Dynamically

I am building an Event Registration system, and am thinking that it should put the Attendee's name on the Ticket (and in the database) as a backup.

Is there a way to easily (and dynamically) display the same number of Text-Boxes as the # of Attendees entered?

For example, let's say the Customer (payor) wants to buy Tickets for herself and 5 friends to a Banjo Festival. 

Right now, I just have a drop-down box to capture the head-count, but it would be nice to have 5 Text-Boxes (or something appear) so that the Customer can easily type in the Names of the 5 Attendees *without* having to suffer numerous other clicks and/or screens.

Follow me?

Is there a way to do that?

Thanks,



Debbie

Here is my dilemma and thank you in advance!

I am trying to create a variable variable or something of the sort for a dynamic associative array and having a hell of a time figuring out how to do this. I am creating a file explorer so I am using the directories as the keys in the array.

Example:
I need to get this so I can assign it values

$dir_list['root']['folder1']['folder2'] = value;

so I was thinking of doing something along these lines...

if ( $handle2 = @opendir( $theDir.'/'.$file ))
{
    $tmp_dir_url = explode($theDir);
    for ( $k = 1; $k < sizeof ( $tmp_dir_url ); $k++ )
    {
        $dir_list [ $dir_array [ sizeof ( $dir_array ) - 1 ] ][$tmp_dir_url[$k]]
    }

this is where I get stuck, I need to dynamically append a new dimension to the array durring each iteration through the for loop...but i have NO CLUE how

So say i have this:

Code: [Select]
<link rel="stylesheet" media="all" type="text/css" href="_css/styles.css" />
now the file that is linking to that is 3 directories deep, besides using a rel or absolute link, could i define the path by using something like this

Code: [Select]
<link rel="stylesheet" href="<?php require($_SERVER['DOCUMENT_ROOT'] . "/_css/portfolio-styles.css"); ?>" type="text/css" />
but this is actually opening the CSS in the header

thanks for any explanation on how to do this

I have a listener which executes a HTTP request to a remote API before the User entity is persisted and uses the response to set one of the entity's properties.  It will also listen for update and remove and will make the appropriate HTTP request to the API but will not modify the entity.  All works as desired... Almost.  If when persisting the entity, I have some error, the remote API and my application become out of sync.  I wish to change my application to perform a second call to the API if an error occurs and reverse the previous call.  My thoughts on how to implement a

Place a try/catch block when executing the query.  Don't like this approach. Add an ExceptionListener which somehow retrieves the entity and makes the applicable changes.  Maybe part of the solution, but too complicated to be the full solution. When adding, updating, or deleting a user from the remote API under UserListener's three methods, adding a callback which gets executed upon a PDOException.  I think this is the best approach and expanded my thoughts below.

 

<?php

namespace App\EventListener;

use Doctrine\Persistence\Event\LifecycleEventArgs;
use App\Service\HelpDeskClient;
use App\Entity\AbstractUser;

final class UserListner
{
    private $helpDeskClient;

    public function __construct(HelpDeskClient $helpDeskClient)
    {
        $this->helpDeskClient = $helpDeskClient;
    }

    public function prePersist(AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->addUser($user);   //$user will be updated with the HTTP response
    }

    public function preUpdate(AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->updateUser($user);
    }

    public function preRemove (AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->deleteUser($user);
    }
}

Okay, how do I actually do this?  Was thinking of modifying UserListner as follows:

//...
use Symfony\Component\HttpKernel\KernelEvents;

final class UserListner
{
    // ...
    
    public function prePersist(AbstractUser $user, LifecycleEventArgs $event)
    {
        $this->helpDeskClient->addUser($user);
        
        $event->getObjectManager()->getEventManager()->addEventListener(KernelEvents::EXCEPTION, function($something) use($user) {
            // Use $this->helpDeskClient to reverse the changes
        });
    }
    
    // Similar for update and remove
}

 

But when trying this approach, I get a PDOException, but my callback never gets excecated.  I've also tried replacing KernelEvents::EXCEPTION with '\PDOException' (note the quotes) with no success.

Any ideas what I should be doing differently?

Maybe some totally different approach?  I suppose I could make the request to the API after the DB query is complete for updating and deleting, but not for adding.

i have a database field called photo. it is used to generate photo id in a software progam for our soccer league. I also want to be able to view the photo on our approval page. could someone help me with the coding of the http h-link? i am having issues with it.

the photo field has the following paramaters: images/picture.jpg

i want the link on the approval page to look like this: <a href="http://bccsl.org/managers/images/picture.jpg">"http://bccsl.org/managers/images/picture.jpg</a>


thanks
