PHP - How To Randomize A Featured Calandar Event In The List Mode

This topic has been moved to PHP Applications.

http://www.phpfreaks.com/forums/index.php?topic=330163.0

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.

<script>
//Calculate Labour
    function filllabour(aa) {
	
	//Parse aa
	
	var the_string = aa;
	var parts = the_string.split('-', 2);

		// After calling split(), 'parts' is an array with two elements:
		// parts[0] is 'left or -'
		// parts[1] is 'right of -'

	var the_text = parts[0];
	var the_num  = parts[1];
	
	//Parse aa

	var dblQuantity = document.getElementById('lqlabour-' + the_num).value-0;
	var curRate = document.getElementById("llabour-" + the_num).value-0;
	var curRateHelper = document.getElementById("lhelper-" + the_num).value-0;
	var dblMarkup = document.getElementById("lmarkup-" + the_num).value-0;
	var curTotal = parseFloat(dblMarkup) / 100.0;
	llinetotal = ((dblQuantity * curRate) + (dblQuantity * curRateHelper)) * (1 + curTotal);
	llinetotal = llinetotal.toFixed(2);
    document.getElementById("ltotal-" + the_num).value = llinetotal;
	//document.getElementById(the_num).value = ("test");
	//alert(the_num);
	
	
	//collect all line totals	
	var inputs = document.getElementsByName("ltotal[]");
	var laboursubtotal = 0;

	for (var i = 0.00; i < inputs.length; i++){
		if (inputs[i].type = "text"){
			laboursubtotal += parseFloat(inputs[i].value, 10);
		}
	}
	//collect all line totals
	laboursubtotal = laboursubtotal.toFixed(2);
	document.getElementById("labourtotal").value = laboursubtotal;
	
		
	filltotal();
	
	
    }
//Calculate Labour

hi, in ie11 we are forced to use compatibility mode for one of our web applications written in php.  above is a script that from what I understand is the error is with getElementsByName.  any suggestions for me in ie11?  

I'm not a programmer, so sometimes the php.net/manual reads like a foreign language to me.  I have a quick interpretation question:

I'm generating data in PHP for a MySQL stored procedure that has two comma separated value inputs.  The second input is always a series of 0's and 1's.  I'm trying to count the number of 1's for the second input (in the example below, it would be "3").

Example input sent to MySQL:$query_resolve = "CALL spParticipant_Test ('188,216,342,81,117,56','0,1,1,0,0,1')";

http://www.php.net/manual/en/function.count-chars.php is mostly helpful, but I am hoping for clarification on the mode I want to run.
Quote

Depending on mode count_chars() returns one of the following:

0 - an array with the byte-value as key and the frequency of every byte as value.
1 - same as 0 but only byte-values with a frequency greater than zero are listed.
2 - same as 0 but only byte-values with a frequency equal to zero are listed.
3 - a string containing all unique characters is returned.
4 - a string containing all not used characters is returned.


Do I want to run mode "1"?  Thanks so much for any feedback!

Hello,    How can I create a webpage using HTML and have a div wrapper for the page become FULL SCREEN?   I'm guessing this would be done with Javascript. 

My my.cnf file has three sections (mysqld, mysqld_safe, mysql).  It seems that they represent different modes which MySQL runs in.  Is this correct?  I read that some recommend running in safe mode.  Should I be if it is being used to support PHP?  I typically start MySQL as "service mysqld start" when running Centos. How should I be starting it if I want it in safe mode.
 

CREATE TABLE user (username varchar(20),password varchar(20),level varchar(20),PRIMARY KEY(username));

INSERT INTO `user` VALUES ('a', 'pass1', 'admin');

INSERT INTO `user` VALUES ('c', 'pass3', 'user');

Hey all

Im trying to find a way to combine images but set the blend mode, like in Photoshop, selecting how layers are blended together.

I have looked at all the docs for GD with no luck...

Cheers in advanced

can we set limit in safe mode as the hosting company would not off the safe mode so please help i get following error,

Warning: set_time_limit() [function.set-time-limit]: Cannot set time limit in safe mode in /home/evercash/public_html/5dollarmatrix.co.cc/admin.php on line 190

elseif($b=="Compress Matrix") {
set_time_limit(6000);
include "config.php";

Not sure at all if this is the right place for this post, but it seemed the most applicable spot. Mods, please move this thread if it is more appropriate elsewhere.   OK - We've got a client that's using - as far as I can tell - exclusively IE11 and has been running into an issue where IE is apparently deleting the contents of the 'Compatibility View Settings' when the browser is closed and/or the browsing history is cleared. According to the research I've done, this was a design decision by Microsoft when they updated IE to only display the 'broken page' icon when the browser thinks the page is broken (regardless IE's actual ability to correctly parse the page) and is fairly well documented in several different places on the Interwebs.   So, I know the issue, and I know that adding an "X-UA-Compatible" meta-tag in the target page's HTML should take care of the problem. The issue I'm having is this - we're redoing the site. Unfortunately, we're not redoing the pages that are causing the current problem, and the client has talked with someone who made mention of (rough quote here) 'a small bit of code that could be added to the link' that would force IE to render in compatibility mode.   I'm assuming the client's source is talking about the meta-tag in the link target page, and I haven't found anything in my Google searches to discount that theory, but I thought I'd ask here before I spoke with them about it in case I'm wrong.   Is there a flag that I can simply append to the URL that IE will parse and force a specific release-compatible view? Or really any way to force IE to render a webpage to a certain version that doesn't entail messing up the display to every other browser ever made or modifying the rendered page's source HTML?

Hello, forgive me for this question in advance. I have looked all day for a fix to this and nothing I have come across has resolved this. My host upgraded to the most recent PHP several months ago and since it has thrown errors on certain scripts. I have gotten tired of looking at them and haven't been able to find a fix on my own so here I am. I am getting the below error.    Notice: Undefined index: mode in /home4/mesquiu0/public_html/NSDisplay/NSStorms-include.php on line 38

if ($_REQUEST['mode'] == 'expired') {                    // We only want the expired storms
	$filetoRead = $expiredfile;
	$arraytoUse = $Expired;
} else {
	$filetoRead = $stormfile;
	$arraytoUse = $Active;
}

I am pretty sure it needs an inset call but not sure how to go about formatting that as I have done with the others errors I have come across. Any suggestions to this error?   -Thanks!

why is this code not working? in php i have the following...

$keywords = "+hello +world";
$query= "SELECT * FROM forums WHERE MATCH (topics) AGAINST ('$keywords' IN BOOLEAN MODE)";
$results = mysqli_query($database, $query);
$row =  mysqli_fetch_assoc($results);

$topics = $row['topics'];
echo $topics;

Warning: mysqli_fetch_assoc() expects parameter 1 to be mysqli_result, boolean given...

i run several wordpress on domains - and wthin the wordpress i have a plugin that allows uploads of images -within a certain plugin

the interesting thing: image upload is - sometimes possible and sometinmes impossible:

see here the circumstances -

PHP Version : 5.3.28
PHP Safe Mode : On

image upload is impossible -

and on the same server - a second vhost

PHP Version : 5.3.28
PHP Safe Mode : off

image upload is possible

why is this so - does it have to do with the safe-mode -
