PHP - Link The Reference Id With User

Hi,

I just need someone to check that a couple of lines I've written do what I believe them to do... i.e. check my logic!

I'm developing a booking form for booking on events. Each booking needs a unique reference, which needs to be meaningless to the customer, so I am BASE36 encloding it.

As the booking is be saved to a MySql database, my approach is to use the auto-incremented ID for the record to make the reference unique. The increment starts at 10000, and I add a random number before coding to make the encoded reference longer. I then BASE36 encode it to make it appear random.

Am I right in thinking the reference produced WILL be unique ... provided the auto-inc ID is unique?

$ref = rand(100,999) . $auto_incremented_id; //e.g. 354 & 10012 = 35410001
$ref_encoded = strtoupper(base_convert($rand, 10, 36)); // e.g.UD4J8P
Thanks

Hello, I've just started learning PHP, JavaScript and I've got a big problem on my website. I'm getting this ReferenceError. I know what's the problem, but I don't know how to solve it, and I know people can do it for money but I don't have money, I'm searching for someone who's willing to help newbie. As I said I'm begginer, and I know something. The main problem is because I want to use GKPlugin and Player(jwplayer). Plugin need to use object, example:

<object id="flashplayer" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="600" height="400">
<param name="movie" value="player.swf" />
<param name="allowFullScreen" value="true" />
<param name="allowScriptAccess" value="always" />
<param name="FlashVars" value="plugins=plugins/proxy.swf&proxy.link=http://www.vidbull.com/53qx9uo10k5d" />
<embed name="flashplayer" src="player.swf" FlashVars="plugins=plugins/proxy.swf&proxy.link=http://www.vidbull.com/53qx9uo10k5d" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="600" height="400" />
</object>

Script is generetad just to embed with iframe, and the problem is when I replace it with object, then I'm getting this error. I know that JS can't "call" that iframe to show because I've replaced it with object. You guys probably know about what I'm talking. I'm just searching for some instructions, guidelines from you.
 

    ReferenceError: embeds is not defined
    

    if (embeds[embedid].indexOf("rapidplayer")== iframe_ad){

Here's the rest of code, I think it's used to show iframe.

 

    elseif (substr_count($link,"gorillavid")){
    $video_id = explode("/",$link);
    if (isset($video_id[count($video_id)-1])){
    $video_id = $video_id[count($video_id)-1];
    $embed = '<object id="flashplayer" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"                                                                      width="600" height="400">
    <param name="movie" value="http://www.kiinc.com/videott/player.swf" />
    <param name="allowFullScreen" value="true" />
    <param name="allowScriptAccess" value="always" />
    <param name="FlashVars" value="plugins=http://www.kiinc.com/videott/plugins/proxy.swf&proxy.link=http://gorillavid.in/'.$video_id.'" />
    <embed name="flashplayer" src="player.swf" FlashVars="plugins=http://www.kiinc.com/videott/plugins/proxy.swf&proxy.link=http://gorillavid.in/'.$video_id.'" type="application/x-shockwave-flash" allowfullscreen="true" allowScriptAccess="always" width="600" height="400" />
    </object>';

This is the original code. Don't look at providers(source as gorillavid) because I used gorillavid in previous an posted another example from another source (zalaa)
 

    elseif (substr_count($link,"zalaa")){
    $video_id = explode("/",$link);
    if (isset($video_id[count($video_id)-1])){
    $video_id = $video_id[count($video_id)-1];
    $embed = '<IFRAME SRC="http://www.zalaa.com/embed-'.$video_id.'.html" FRAMEBORDER=0 MARGINWIDTH=0 MARGINHEIGHT=0 SCROLLING=NO WIDTH='.$width.' HEIGHT='.$height.'></IFRAME>';

Function which embed links and should embed GKPlugin/Player:

// general image link

    if (!$embed){
    $embed = "<div style='background-color:#000000; width: ".$width."px; height: ".$height."px;text-align:center;cursor:pointer;' onclick='window.open(\"$link\");'>";
    $embed.= "<p style='text-align:center; padding-top: 70px;'>";
    $embed.= "<a href='$link' target='_blank' style='font-size:24px; color: #ffffff !important'>Click here to play this video</a>";
    $embed.= "</p>";
    $embed.= "</div>";
    }
    return $embed;
    }

JavaScript code:

 

  function getEmbed(embedid){
        if (embeds[embedid].indexOf("rapidplayer")== iframe_ad){
            var html_content =     "<div class='fake_embed' id='fake_embed"+embedid+"' onclick='closeFakeEmbed("+embedid+");'>" +

                                        "<iframe src='"+baseurl+"/iframe_ad.php' width='300' height='300' frameborder='NO' border='0'></iframe>" +
                                    "</div>" +
                                    "<div class='fake_embed_bar'><span class='fake_embed_bar_right'></span></div>" +

            jQuery('#videoBox'+embedid).show();
        } else {

hello.

say i have list and i want the correct children under each parent

so i have
$id
$parent_id
$type
$name

in the db i have
4 parents each with 2 children

id=1 - type=parent - parent_id=0 - name=p1
id=2 - type=parent - parent_id=0 - name=p2
id=3 - type=parent - parent_id=0 - name=p3
id=4 - type=parent - parent_id=0 - name=p4
id=5 - type=child - parent_id=1 - name=c1
id=6 - type=child - parent_id=1 - name=c2
id=7 - type=child - parent_id=2 - name=c3
id=8 - type=child - parent_id=2 - name=c4
id=9 - type=child - parent_id=3 - name=c5
id=10 - type=child - parent_id=3 - name=c6
id=11 - type=child - parent_id=4 - name=c7
id=12 - type=child - parent_id=4 - name=c8

so how would i do the code?

i thought i could do it like this but its not working.

Code: [Select]
<?php

$family = Family::find_all();
foreach($family as $familys){

$id = $familys->id;
$type = $familys->type;
$parent_id = $familys->parent_id;
$name = $familys->name;


echo'
<ul>';
if($type == "parent"){
echo $name;
} 
echo' </ul>


<li>';
if($type == "child" && $parent_id == $id){
echo $name;
} 
echo' 
</li>';
}
?>


all i get back is

    p1

    p2

    p3

    p4


no children

??



if i remove Quote

$parent_id == $id

from Quote

if($type == "child" && $parent_id == $id){


i get this

    p1

    p2

    p3

    p4

c1

c2

c3

c4

c5

c6

c7

c8

but they are not listed under the correct parent





i also tried moving the </ul> to the bottom but i get the same
Code: [Select]
<?php

$family = Family::find_all();
foreach($family as $familys){

$id = $familys->id;
$type = $familys->type;
$parent_id = $familys->parent_id;
$name = $familys->name;



echo'
<ul>';
if($type == "parent"){
echo $name;
} 
echo'


<li>';
if($type == "child"){
echo $name;
} 
echo' 
</li>
</ul>';
}
?>



any thoughts?

thanks

Can someone explain this strange behavior:


$aArray = array(
1 => null,
2 => null,
3 => null,
);
foreach($aArray as $key => &$val)
{
$val = "Some Value";
foreach($aArray as $Xkey => $Xval){} // Second foreach
}
var_dump($aArray);

Rsult is:
array(3) {
  [1]=>
  string(10) "Some Value"
  [2]=>
  NULL
  [3]=>
  NULL
}


It looks like second foreach breaks reference, why?

hi,

i have made a website where people resgister their details of them and products.

they have to enter the following details in form

Name of company

name of the product

company address

email id 

password 

mobile number contact

and 

brief details about their company 

after filling all details user is registered on website.

user can then login with email id and pwd.

now after login ..user will get a page where he can upload the photos of products images and their price, so now my question is that when he finishes uploading (|by clicking on upload button) the product images and price text box ..then on final uploaded webspage it should show all other things which he registerd before (company name , mobile number etc) along with images and price...hence the main question that user does not need to enter mobile and address while uploading images and filling proce ..but on the final page it should show mobile and address along with price and images..as user is not going to enter mobile and address again and again as he will have multiple products to upload.

thanks in advance .

I would appreciate your assistance, there are tons of login scripts and they work just fine. However I need my operators to login and then list their activities for the other operators who are logged in to see and if desired send their clients on the desired activity. I have the login working like a charm and the activities are listed just beautifully. How do I combine the two tables in the MySQL with PHP so the operator Logged in can only make changes to his listing but see the others.

FIRST THE ONE script the member logges in here to the one table in MSQL:
<?php
   session_start();
   
   require_once('config.php');
   
   $errmsg_arr = array();
   
   $errflag = false;
   
   $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
   if(!$link) {
      die('Failed to connect to server: ' . mysql_error());
   }
   
   $db = mysql_select_db(DB_DATABASE);
   if(!$db) {
      die("Unable to select database");
   }
   
   function clean($str) {
      $str = @trim($str);
      if(get_magic_quotes_gpc()) {
         $str = stripslashes($str);
      }
      return mysql_real_escape_string($str);
   }
   
   $login = clean($_POST['login']);
   $password = clean($_POST['password']);
   
   if($login == '') {
      $errmsg_arr[] = 'Login ID missing';
      $errflag = true;
   }
   if($password == '') {
      $errmsg_arr[] = 'Password missing';
      $errflag = true;
   }
   
   if($errflag) {
      $_SESSION['ERRMSG_ARR'] = $errmsg_arr;
      session_write_close();
      header("location: login-form.php");
      exit();
   }
   
   $qry="SELECT * FROM members WHERE login='$login' AND passwd='".md5($_POST['password'])."'";
   $result=mysql_query($qry);
   
   if($result) {
      if(mysql_num_rows($result) == 1) {
         session_regenerate_id();
         $member = mysql_fetch_assoc($result);
         $_SESSION['SESS_MEMBER_ID'] = $member['member_id'];
         $_SESSION['SESS_FIRST_NAME'] = $member['firstname'];
         $_SESSION['SESS_LAST_NAME'] = $member['lastname'];
         session_write_close();
         header("location: member-index.php");
         exit();
      }else {
         header("location: login-failed.php");
         exit();
      }
   }else {
      die("Query failed");
   }
?>

................................................. ................................
Now I need the person who logged in to the table above to be able to make multiple entries to the table below

<?
$ID=$_POST['ID'];
$title=$_POST['title'];
$cost=$_POST['cost'];
$activity=$_POST['activity'];
$ayear=$_POST['aday'];
$aday=$_POST['ayear'];
$seats=$_POST['special'];
$special=$_POST['seats'];
mysql_connect("xxxxxx", "xxx350234427", "========") or die(mysql_error());
mysql_select_db("xxxx") or die(mysql_error());
mysql_query("INSERT INTO `activity` VALUES ('ID','$title', '$cost','$activity', '$aday', '$ayear', '$special', '$seats')");
Print "Your information has been successfully added to the database!"
?>
Click <a href="member-profile.php">HERE</a> to return to the main menu
  <?php      
?>

Hi,

so far I have managed to set up a somewhat basic login website with a mysql database backend.

Once they have logged on they go to a "main menu" page.

What I need to define is that user A sees button A but only that button, etc.

(Then of course that same rule would have to apply if they tried to directly go to the page, but I am guessing I can do that in the same way that I currently do to force a login).

If anyone has any tutorials or sample code I would much appreciate it.

Thanks,

Actually, what i want to do is to use the email to fetch the $email,$password and $randomnumber from database after

OK, so I have the following file that has database functions:

<?php

function dbDelete($param){
$conDelete = mysql_connect($url,'username','password',true);
mysql_select_db('my_db',$conDelete);
mysql_query($param,$conDelete);
mysql_close();
   if(isset($conDelete)){
   mysql_close($conDelete);
   }
}
?>

I include the above file in a session handling file.  But for some reason the new file can't call the above function as follows:
<?php
include_once 'the above stated file';
function timeOut(){
        dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'");
   $_SESSION = array();
   setcookie(session_name(),'',time()-4200);
   session_destroy();
}
//CHECK FOR TIMEOUT REQUEST
switch($_GET['xyz']){
   case 'timeout':
   timeOut();
   header("Location: /?xyz=timedout");
   break;
   case 'logout':
   timeOut();
   header("Location: /?xyz=loggedout");   
   break;
   case 'refresh':
   dbUpdate("UPDATE acctussessi SET acctussessi_time = ".time()." WHERE acctussessi_unid ='".$token."'");   
   break;
}
?>

dbDelete isn't being called inside of the TimeOut() function.  The only way it works is by doing the following:

<?php
function timeOut(){
   $_SESSION = array();
   setcookie(session_name(),'',time()-4200);
   session_destroy();
}
//CHECK FOR TIMEOUT REQUEST
switch($_GET['xyz']){
   case 'timeout':
      dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'");
   timeOut();
   header("Location: /?xyz=timedout");
   break;
   case 'logout':
      dbDelete("DELETE FROM acctussessi WHERE acctussessi_usid = '$sessius[0]'");
   timeOut();
   header("Location: /?xyz=loggedout");   
   break;
   case 'refresh':
      dbUpdate("UPDATE acctussessi SET acctussessi_time = ".time()." WHERE acctussessi_unid ='".$token."'");   
   break;
}
?>
But this is annoying and repetitive.  What is going on?

Thanks in advance.

Is it possible to get something as a reference in the script if it is such a http://site.com/home#p1

tried in different ways but #p1 my script does not see

If getValue is given a path which doesn't exist, I can use the isset check to return null.

I can also use the uncommitted $tmp =&$tmp[$key];.  Why does this prevent an undefined index warning?

 

    public function getValue(string $path) {
        $path=explode('.', $path);
        $tmp=$this->config;
        foreach($path as $key) {
            //if(!isset($tmp[$key])) return null;
            //$tmp =$tmp[$key];
            $tmp =&$tmp[$key];
        }
        return $tmp;
    }

 

I am writting a php function that uses mysql to get user data - pretty common, right

Well, my issue is that I need to run a check in my file system.  Users profile pictures are stored in my image directory as .png's.  I need to have my function check that directory and if an image matches their id, then return their information.  I only want the user data if they have an image uploaded.

Here is my current function:

Code: [Select]
function fetch_users_login($limit)
{
$limit = $limit(int);

$sql = "SELECT
                `users`.`id`,
                `users`.`firstname`,
                `users`.`lastname`,
                `users`.`username`,
`user_privacy`.`avatar`
            FROM `users`
LEFT JOIN `user_privacy`
            ON `users`.`id` = `user_privacy`.`uid`
WHERE `users`.`status` > 2
AND `user_privacy`.`avatar` = 1
ORDER BY `users`.`id` DESC
LIMIT 0, {$limit}";

$result = mysql_query($sql) or die(mysql_error());

$users = array();

$i = 0;

while(($row = mysql_fetch_assoc($result)) !== false)
{
$users[$i] = array(
'id' => $row['id'],
'firstname' => $row['firstname'],
'lastname' => $row['lastname'],
);

$users[$i]['avatar'] = getUserAvatar($row['username']);

$i++;
}

return $users;
}

Hi everyone,

This is driving me crazy. I need to reference different files located in different folder structure. For example, I have the following file structure.

/my_project/
/my_project/database/database_script.php
/my_project/index.php

1. If I want to reference /my_project/index.php from /my_project/database/database_script.php, how can I reference it ?
2. From /my_project/index.php to /my_project/database/database_script.php , it's obvious all I gotta do it include("/database/database_script.php").

I use $_SERVER('DOCUMENT_ROOT"), to solve the 1. problem. It works on my XAMPP local machine but when I uplode it onto the server, there's a problem.  The path becomes '/my_project/my_project/database/database_script.php". Is there a universal way (more like a standard way) to reference files in php so that I won't need to change every file path once I upload those onto the server ?

Regards,

Hi Guys

Probably a simple answer to this.

Writing a script where I have a foreach to escape data in a multi dimensionsal array - destined for the database.

I want to preserve the the escaped values in the array so I've passed in the value by referece. See code below:

Code: [Select]
foreach($myarray as $key=>$value){

foreach($value as $k=>$v){

$v =   $mysqli->real_escape_string(&$v);
echo  $v ."<br/>";

}
 
  }


I've switched on error_reporting(E_STRICT), because i read it was good practice to build your scripts with this on.

Anyway - when i pass by reference I get a message as follows:

Quote

Deprecated: Call-time pass-by-reference has been deprecated in C:\wamp\www\wh\C.php on line 105


So if pass by reference is deprecated, what's the alternative?

I realise i could pass the new values to a new array. But does this mean i shouldn't pass by reference anymore?

Many thanks and sorry for going round the planet to ask such a simple question.

Drongo

Hi all, I'm trying to understand passing by reference.  Here is a copy of the code and the results:
Code: [Select]
<?php

        $a1 = 15;
        $b1 = 20;
        
        echo addone($a1, $b1);
        echo "<br/>";
        
        function addone($n1, $n2){
            $n1 = $n1 += 2;
            $n2 = $n2 += 2;
            return $n1 . " " . $n2;
        };
        
        echo addonetwo($a1, $b1);
        
        function addonetwo($n1, $n2){
            $n1 = $n1 += 2;
            $n2 = $n2 += 2;
            return $n1 . " " . $n2;
        }
        ?>
The result output is:
17 22
17 22

If I change the code to add "&" before the "addone" function:
Code: [Select]
function addone(&$n1, &$n2){
            $n1 = $n1 += 2;
            $n2 = $n2 += 2;
            return $n1 . " " . $n2;
        };
Then the output is:
17 22
19 24

I don't understand what's going on.  Why is the "&" incrementing the changed variable and in the first example it's incrementing the variables as defined.
