How can I retrieve an object stored in SplObjectStorage based on a unique key?  Is it possible to do so the way I am attempting to show in my 2 example?

<?php


class Foo
{
    private $storage;
    private $map;


    public function __construct()
    {
        $storage = new SplObjectStorage();
        $map=[];
    }


    public function add(object $obj)
    {
        $this->storage->attach($obj, []);        
    }


    public function assign1($obj,$id)
    {
        $this->storage[$obj] = $id;
    }


    public function findByID1($id)
    {
        $this->storage->rewind();
        while($this->storage->valid()) {
            if($id == $this->storage->getInfo()) {
                return $this->storage->current();
            }
            $this->storage->next();
        }
        return false;
    }


    public function assign2($obj,$id)
    {
         $this->map[$id]=spl_object_hash($obj);
    }


    public function findByID2($id)
    {
        $hash=$this->map[$id];
        return getObjectBasedOnHash($hash);
    }


}

$obj=(object)['foo' => 'bar'];
$foo=new Foo();

//Now this object's id is known $id=11111;

$foo->assign1($obj,$id); $obj1=$foo->findByID1($id); $foo->assign2($obj,$id); $obj2=$foo->findByID2($id);

Hi All,

I am using JTable Plug in and using PHP code as my server language.

The plug in requires json encode in this format,

** please ignore other data. except for "RecordDate" **

{
 "Result":"OK",
 "Records":[
  {"PersonId":1,"Name":"Benjamin Button","Age":17,"RecordDate":"\/Date(1320259705710)\/"},
  {"PersonId":2,"Name":"Douglas Adams","Age":42,"RecordDate":"\/Date(1320259705710)\/"},
  {"PersonId":3,"Name":"Isaac Asimov","Age":26,"RecordDate":"\/Date(1320259705710)\/"},
  {"PersonId":4,"Name":"Thomas More","Age":65,"RecordDate":"\/Date(1320259705710)\/"}
 ]
}

What i have for my output is,

{
"Result": "OK",
"TotalRecordCount": 1,
"Records": [
{"Row": "1","emp_id": "Nhhh","course1": {"date": "2017-01-06 00:00:00","timezone_type": 3,"timezone": "Asia\/Brunei"}
}]
}

Im currently using datetime as my data type in my database (SQL Server), and the output is empty due to wrong json date format.

thanks for the help.

Hi,

Apologies If I've got the title wrong but I'm trying to obtain a value from an array, however, it's an object (?)

Array
(
    [test] => WC_Coupon Object
        (
            [code] => test
            [id] => 1529
            [exists] => 1
            [discount_type] => percent_product
            [coupon_amount] => 10
            [individual_use] => yes
            [product_ids] => Array

I need to get coupon_amount

I thought I could use $my_coupon[0]->coupon_amount; but believe I've confused myself or misunderstood!

Any advice is gratefully received!

Thanks

Hi, anyone know how I can restrict the values displayed in a Select, taken from a MySQL query, which have been edited before output?

The original values are all unique so doing a COUNT or DISTINCT in MySQL won't work. This is the PHP I'm using to pull and edit the values:

        $getusers = $mysqli->query("SELECT order_discount_code FROM orders ORDER BY order_discount_code ASC");
            while ($row = $getusers->fetch_assoc()) {
                $vouchercode = $row['order_discount_code']; //These values are all unique but share common characters e.g the first three characters of the string
                $agencycode = mb_substr($vouchercode, 0, 3); //I'm doing this as I want to have just the first three characters show in the form Select that contains this query
        echo '<option>'.$agencycode.'</option>';
            }

Hello, 

First post, very not expert.

I have this page I'm editing (from a wordpress theme called "lay theme"): http://mtthsstffn.altervista.org/tagnacht/

In this carousel that scrolls images, I need to move the "next" "prev" clickable area slightly outside the images. I think I want to make two invisible divs, left and right, that overlay the image and occupy the center-to-left and center-to-right area of the carousel, with a variable length I can define.

A friend suggested to add this 

<div id="nav-left" style="
    height: 800px;
    display: block;
    width: 50%;
    position: absolute;
    top: 0;
    ;
    pointer-events: left;
    cursor: move;
"></div>

inside <div class="lay-carousel-wrap immediate">

I think it can be right, but where can I find the files I need to do it? 

I looked around the whole website and couldn't find the HTML with this element, hence I think it's automatically generated with PHP, but I have no idea where to start for this.
Thanks for any help!

 

A remote client has connected to the following server described at the bottom of this page, has told the server that its GUID is 123456789, and the server has created a map between this GUID and the specific client connection.

Another script index.php is ran through Apache on the same machine as the sockets server.

<?php

$guid=123456789;
$data='{"message":"hello"}';

someFunctionToSendDataToSocketsServer($guid,$data);

Somehow, I would like to have index.php send $guid=123456789 and $data='{"message":"hello"}' to the sockets server, and then execute:

$client=$this->findConnectionByGuid($guid);
$client->write($data);

someFunctionToSendDataToSocketsServer() should be a blocking function up to the sockets server writing the data (but not that the client received it and acknowledged it) and should return true/false (or a 200/400 header, or some other means to indicate status).

At first, I was thinking of using a ReactPHP HTTP server operated on the same loop as the sockets server.  index.php would then use curl to send it to the HTTP server, the HTTP server on request event would get the data, and if valid format send the data to the client and return a 200 header, and if not valid format, return a 400 header.  ReactPHP, however, says that the HTTP server is not stable.

Another option would be to add a sockets client to the server machine and have index.php use that client to send the data to the sockets server.  I don’t think this make sense, however, as index.php is not communicating bi-directional with the sockets server.  Also, it adds a little complication as the sockets server is currently designed to receive connections from remote clients which send the server their unique GUID.  Lastly, from a security standpoint, I don’t want the remote clients to somehow gain privileges available to only index.php.

Or maybe a redis queue where index.php places the content in the queue, and it pops out in the server script where it is sent.  I am not sure how the true/false status would work.

Or maybe something else altogether?

Any advice?

So I have mySQL Workbench that connects to my host and they require an SSH Connection.  I have that option set in mySQL workbench.  I am able to connect just fine and look at the database that my developer has coded.

Now I actually want to use PHP to connect to the database and pull some information out to utilize on another domain name.

Can anyone give me a link or help me understand, how can I connect to a mySQL db using SSH in a PHP script?

Hi All!

This is my second week of PHP. I'm going through a PHP course at the moment so i'm pretty certain i've made a stupid mistake somewhere!

I'm trying to get a date that's entered in my CMS panel to show on the front-end.

I've defined the variable departure_date --> got the raw data --> created a new date object --> tried to display the date object in the format j M Y.

I believe there is something wrong with how i am defining the date object in my echo statement.

I forgot to mention this is a wordpress website i'm working on with ACF custom fields if that helps.

$departure_date = get_field('departure_date', false, false);
$departure_date = new DateTime($departure_date);
$cruise_line = get_field('cruise_line');
$ship = get_field('ship');

if(get_field('ship'))
{
    echo 'Departs' . $departure_date->format('j M Y') . get_field('cruise_line') . ' | ' . get_field('ship');

}

I recently uploaded my client's site onto a temporary server so that they could get started on data input while I fine tune the design.

When I launched it however, one of my sliders and one of my pages broke down completely [note: this only occurs on the server side; my localhost site continues to work perfectly].

I narrowed it down to my use of the date_create_from_format() function as I use it on both pages, and when I remove the element holding that bit of php, the site works fine. I have scoured my file for any missing semi-colons, or brackets, and I can't find any glaring errors. Here is my code as it was orginally on my localhost.

<?php
  $end = date_create_from_format('Ymd',$ending_date);
  $start = date_create_from_format('Ymd',$starting_date);
  echo "<span class='month'>" . $start->format('F') . "</span>";
  echo " ";
  echo "<span class='day'>" . $start->format('j') . "</span>";
  echo ", ";
  echo "<span class='year'>" . $start->format('Y') . "</span>";

  echo " - ";

  echo "<span class='month'>" . $end->format('F') . "</span>";
  echo " ";
  echo "<span class='day'>" . $end->format('d') . "</span>";
  echo ", ";
  echo "<span class='year'>" . $end->format('Y') . "</span>";
  echo ", $location";
 ?>

I have also tried converting it from the object to the procedural function (See below) but the result is the exact same.

 

<?php
  $end = DateTime::createFromFormat('Ymd', $ending_date);
  $start = DateTime::createFromFormat('Ymd', $starting_date);
 ?>
 <?php
  echo "<span class='month'>" . date_format($start,'F') . "</span>";
  echo " ";
  echo "<span class='day'>" . date_format($start,'j') . "</span>";
  echo ", ";
  echo "<span class='year'>" . date_format($start,'Y') . "</span>";

  echo " - ";

  echo "<span class='month'>" . date_format($end,'F') . "</span>";
  echo " ";
  echo "<span class='day'>" . date_format($end,'d') . "</span>";
  echo ", ";
  echo "<span class='year'>" . date_format($end,'Y') . "</span>";
  echo ", $location";
 ?>

Someone on stackoverflow pointed out that there might be an issue regarding timezone being unidentified, so i made the following modification but the problem persisted.

 <?php
  $end = DateTime::createFromFormat('Ymd', $ending_date, new DateTimeZone('America/Toronto'));
  $start = DateTime::createFromFormat('Ymd', $starting_date, new DateTimeZone('America/Toronto'));
 ?>

Really at a loss here and the deadline is looming. Anyone have any ideas?

I have a form with a table with columns and many rows.  The form uses Post and submits to an insert.php  I am looking for an example of how I can insert the table info into a mysql table.  I know I should use a while loop but unsure how to step through the form info.

Can someone suggest or provide and example that I can follow, or a tutorial somewhere?

Thanks

I made a mysql query in php as given below

$Q = "SELECT length, width FROM statxyx WHERE siteid='$siteid'";
          $R = mysqli_query($DB,$Q);
          //start loop
          //while or foreach
          while($row = mysqli_fetch_assoc($R)){
            echo "['7C6Buh',{$row['length']},{$row['width']}],\r\n";
          }

The output is like

If I start this client when the server isn't started, I get the following error.  If I get rid of the addPeriodicTimer, it doesn't appear to happen.  What is going on?  Thanks

EDIT.  A clue!  The following makes the error go away, and exit('addPeriodicTimer'); is executed.  Still would like to know what is going on.

// $socket = new TimeoutConnector(new TcpConnector($this->loop), 10, $this->loop);
$socket = new TcpConnector($this->loop);

<?php


namespace DataLogger;


use React\EventLoop\Factory;

        });
        $this->loop->run();

Hi,

I'm trying to send a mail from a Webpage (PHP), running on a Raspberry Pi (Apache2, PHP5).

The Raspberry Pi is behind a Router from my ISP (Telenet) and they block the SMTP-port(25).

But I successfully installed sSMTP with all needed configuration, and I'm able to send emails through the mailhub of my ISP (what off course is what they rather like).

sudo nano /etc/ssmtp/ssmtp.conf

Contains:

root=pieterjan@pieterjan.pro
mailhub=smtp.telenet.be:587
rewriteDomain=pieterjan.pro
hostname=pieterjan.pro
UseTLS=YES
UseSTARTTLS=Yes
AuthUser=my_account@telenet.be
AuthPass=my_password
AuthMethod=LOGIN
FromLineOverride=YES

And my Reverse-aliases-file:

sudo nano /etc/ssmtp/revaliases

Contains:

root:my_account@telenet.be:smtp.telenet.be:587
pi:my_account@telenet.be:smtp.telenet.be:587

With this configuration I'm able to send an e-mail using this bash-command:

echo "Email body" | mail -s "Test Subject" some-email@address.com

Next step:

I've tried to change the configuration of PHP5 to use the PHP mail() command:

sudo nano /etc/php5/apache2/php.ini

Contains:

[mail function]
; For Win32 only.
; http://php.net/smtp
;SMTP = localhost
; http://php.net/smtp-port
;smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = pi@pieterjan.pro

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = /usr/sbin/sendmail -t -i -f pi@pieterjan.pro

; Force the addition of the specified parameters to be passed as extra parameters
; to the sendmail binary. These parameters will always replace the value of
; the 5th parameter to mail().
;mail.force_extra_parameters =

; Add X-PHP-Originating-Script: that will include uid of the script followed by t$
mail.add_x_header = On

; The path to a log file that will log all mail() calls. Log entries include
; the full path of the script, line number, To address and headers.
;mail.log =
; Log mail to syslog (Event Log on Windows).
;mail.log = syslog

I've already tried about everything. I think sendmail should only be used in WAMP and therefore is not applicable. Some say sendmail is automatically linked to ssmtp. But I actually already tried loads of configurations:

sendmail_path = /usr/sbin/sendmail -t
sendmail_path = /usr/sbin/sendmail -t -i
sendmail_path = /usr/sbin/sendmail -t -i -f pi@pieterjan.pro
sendmail_path = /usr/sbin/ssmtp -t
sendmail_path = /usr/sbin/ssmtp -t -i

PHP-code:

<?php
    error_reporting(E_ALL|E_STRICT);
    ini_set('display_errors',1);

    $res = mail("pieterjandeclippel@msn.com", "Subject", "Hello!");

    echo '<hr>Result was: ' . ( $res === FALSE ? 'FALSE' : 'TRUE') . $res;
    echo '<hr>';
    phpinfo();
?>

This script is hosted here.

But nothing actually seems to work, and I'm getting this error:

cat /var/log/mail.log

Last error from the log-file:

Jan  8 20:53:38 pieterjan sSMTP[9209]: Creating SSL connection to host
Jan  8 20:53:38 pieterjan sSMTP[9209]: SSL connection using DHE_RSA_AES_128_CBC_SHA1

What is the problem and how can I fix this?

Hello PHP freaks, I'm new to the forum but am here due to an problem I haven't been able to solve. I am working on something which I believe is a simple problem / solution. I'm still a beginner at PHP and love the language so far. I'm trying to override a value in my WordPress Theme so that it outputs an h3 instead of h5. If anyone would be able to walk me through a solution I'd be really grateful. I'm looking forward to learning from my mistakes on this one.

I would like the 'selector' line to read as 'selector' => '.et_pb_toggle.et_pb_toggle_item h3',

/* Source Code from Parent Theme Toggle Found on line 7170*/
et_pb_print_module_styles_css( 'et_pb_toggle', array(
  array(
    'type'         => 'font-size',
    'key'         => 'title_font_size',
    'selector'     => '.et_pb_toggle.et_pb_toggle_item h5',
  ),
  array(
    'type'         => 'font-style',
    'key'         => 'title_font_style',
    'selector'     => '.et_pb_toggle.et_pb_toggle_item.et_pb_toggle_open h5',
  ),
  array(
    'type'         => 'font-style',
    'key'         => 'inactive_title_font_style',
    'selector'     => '.et_pb_toggle.et_pb_toggle_item.et_pb_toggle_close h5',
  ),
  array(
    'type'         => 'font-size',
    'key'         => 'toggle_icon_size',
    'selector'     => '.et_pb_toggle.et_pb_toggle_item .et_pb_toggle_title:before',
  ),
  array(
    'type'         => 'padding',
    'key'         => 'custom_padding',
    'selector'     => '.et_pb_toggle.et_pb_toggle_item',
  ),
) );

Here is what I tried that didn't work and I have a few ideas but am not really sure how to execute them properly. As this code below gave a PHP error.

Fatal error: Call to undefined function et_pb_toggle() in /home/content/p3pnexwpnas05_data01/49/3127149/html/wp-content/themes/Holmes Child Theme/functions.php on line 17

//modifies array for toggle switching h5 => h3
function hms_module_modifier() {
 et_pb_toggle( array(
      'selector' 	=> '.et_pb_toggle.et_pb_toggle_item h3'
    )
  );
}
//Runs module modifier
 hms_module_modifier();

Hi,

Apologies if this is a basic question but either I've misunderstood or I'm being daft 

In one function I have:

function create_coupon() {
	$unique_coupon_code = $coupon_name.'-'.$date; #concatenate the two
	return $unique_coupon_code;
}

Then in my second function I try to get that variable ($unique_coupon_code) to use again:

function use_coupon() {
	echo $unique_coupon_code;
}

But it returns blank?

However, if I echo $unique_coupon_code; in the first function, it does show a value

What am I doing wrong?

Thanks

Hey guys.

I have this php code and it tells me there a problem, but I can seem to figure out what the problem is. Hope you can help.

Here is the code -

I have a form to submit a email address and password. I get an undefined index error and if I try to use isset to fix the undefined index error I get the following error Cannot use isset() on the result of an expression (you can use "null !== expression" instead) in and I have tried to use the suggestions to solve the problem  but than another error pops up. 

Here is my php code . All help greatly appreciated.
