PHP - Set Order For Staff Picking Vacation

Hiya guys,

I'm having problems with a code i have written, it seems that nor google or my own search engine is picking up the links?
And i don't understand why. I know the following code has a div on click rule, but i have also added an a href.

I tried the basic link which is also not picking up.

Code: [Select]
<?php

$old_pattern = array("/[^a-zA-Z0-9]/", "/_+/", "/_$/");
$new_pattern = array("_", "_", "");
$i = '1';


while($row = mysql_fetch_array($result))
{

${videoData_.$i} = mysql_query("SELECT * FROM videoData WHERE qid=".$row['id']."") or die(mysql_error());
${row_.$i} = mysql_fetch_array(${videoData_.$i});

${vote_.$i} = mysql_query("SELECT SUM(votes) FROM answers WHERE qid=".$row['id']."")or die(mysql_error());
${votes_.$i} = mysql_fetch_array(${vote_.$i});


$pagelink = strtolower(preg_replace($old_pattern, $new_pattern , $row['question']));


echo '<div class="NVP-div" ';
echo 'onclick="location.href=\'http://www.thevideopoll.com/polls/';
echo $link = "".$row['id']."-_-".$pagelink.".php";
echo '\';" style="cursor: pointer;"';
echo '>';

echo '<img style="float:left; margin-left:25px;" src="http://img.youtube.com/vi/'.${row_.$i}['videoID'].'/default.jpg">';
echo '<p class="NVP-vote">';
echo ${votes_.$i}['SUM(votes)'];
echo ' Votes';
echo '</p>';
echo '<br>';
echo '<a class="new-video-links" href="http://www.thevideopoll.com/polls/';
echo $link = "".$row['id']."-_-".$pagelink.".php";
echo '" title="'.$row['question'].'">';


echo "".$row['question']."";
echo "</a>";

echo '</div>';

$i++;

}

?>

Hi guys,

For a project I made sort of a custom cron database. Database has 4 columns: ID (auto increment), TaskID, DateTime, Locked.

I'm running a 1 minute cron in the form of a php script. The script itself starts with a query that loads a task with 'Locked != 'Y' and DateTime < NOW( ).

It then locks the task (by flagging the 'Locked' field in the db) and launches another script that finishes it. That last script deletes the task when finished from the cron database.

Problem is, at certain peek hours, the system would get laggy, there'd be a bunch of tasks stacking up and it would get behind on the schedule.

In order to combat that, I made an extra 1 minute cron, launching the same script. Now, my problem: mysql is too slow

In principle, there shouldn't be any problem: all tasks picked up by either instance of the script would be locked so the other instance wouldn't be able to pick up the same task. The problem occurs when both instances are booted at the same time (well, one after the other but with a minuscule time difference between them) and they both at the same time run the query to get a 'free' task from the database: the system will give them both the same task before either of the script instances has the time to lock it up.

I'm trying to think of some solutions but I'd like your feedback on what solution would be best.

- Putting an exclusive lock on the php file is not an option for me since I still want to run the script, I just need it to pick up an exclusive task.
- Other option: having the script open with a random sleep of (1, 10) seconds, it will have the script instances pick up a task at a different time, giving the other instance time to lock it up. Obvious disadvantage: I'm losing time.
- Using a file as a flag. Set a directory and create a file in it. Check if this is the only file in the dir, if yes: start right away. Otherwise: go to sleep for 2 seconds (should be plenty of time to run 2 queries in the other instance). What is the fastest method of doing a directory scan though, glob()?

My question: what's the fastest/best way to solve this? Thanks!

Hi good people, i'm vary new in this and i'm having trouble with PHP while writing some project for school and because i find many answers on this forum till now i decide to post this.. so here is my problem:
I'm trying to make a web page for students and profesors where students (when they are loged in) will be able to sign a date for their exam so i made a form like this :

Code: [Select]
<form method="POST" action="">
choose exam:
<p><select name="exams">
<option value="k1D">exam 1</option>
<option value="k2D">exam 2</option>
<option value="k3D">exam 3</option>
</select></p>
choose date:
<p><select name="dates">
<optgroup label="Zimski rokovi">
<option value="2011-02-01">01.02.2011.</option>
<option value="2011-02-07">07.02.2011.</option>
<option value="2011-02-15">15.02.2011 </option>
<optgroup label="Ljetni rokovi">
<option value="2011-05-21">21.05.2011.</option>
<option value="2011-05-28">28.05.2011.</option>
<option value="2011-06-04">04.06.2011.</option>
</select></p>
<input type="submit" value="Prijavi ispit" name="prijavi">
</form>
table for students in mysql has columns for every exam (k1D , k2D..) but how can i make so that student can pick wich exam he wants to sign on some of dates (wich column he wants to fill with wich of dates)  ?

i tryed some variations of :

Code: [Select]
$k1D = $_POST['dates'];
$kol = $_POST['exams'];
mysql_query(" UPDATE studenti SET '$kol' = '$k1D'
WHERE ID = '3'");

but i'm just getting different errors..

Hi everyone. I'm very new into self learning programming. Presently I'm trying to develop a simple basic Robot that would only Place a Market Order every seconds and it will cancel the Order every followed seconds. Using the following library:
https://docs.b2bx.exchange/en/_docs/api-reference.html#private-api

It would place Trade Order at a ( Price = ex.com api * Binance api Aggregate Trades Price)

I have already wrote the api to call for xe.com exchange rate with php 

<?php

$auth = base64_encode("username:password");
$context = stream_context_create([
    "http" => [
        "header" => "Authorization: Basic $auth"
    ]
]);
$homepage = file_get_contents("https://xecdapi.xe.com/v1/convert_from?to=NGN&amount=1.195", false, $context );
$json = json_decode($homepage, TRUE);
foreach ($json as $k=>$to){
    echo $k; // etc
};


?>

And also for the Binance Aggregate Price in JavaScript

 

<script>
var burl = "https://api3.binance.com";

var query = '/api/v3/aggTrades'; 

query += '?symbol=BTCUSDT';

var url = burl + query;

var ourRequest = new XMLHttpRequest();

ourRequest.open('GET',url,true);
ourRequest.onload = function(){
    console.log(ourRequest.responseText);
}
ourRequest.send();
</script>

  My problem  is how to handle these two api responds  and also the functions to use them to place a trade and cancel it.
Please help me out. Thanks in advance on any help.

Hello,


I have classes in a database with no set UNIX date, just the day like Wednesday and in two other columns the start and end dates.


I want to be able to order by the day first and then by end_time but php orders the day column by spelling and not the day it holds in chronological order.


Is there anyway to change the query to order the day column as a date?


See the query below?


Code: [Select]
$query = "SELECT * FROM zumba_timetable WHERE end_time>'$current_time' ORDER BY day, end_time ASC LIMIT 0,1";

Hi there, just registered and in need of help, this looks a good place to start!
I'm a php beginner so please bear with me

I have a mysql database which holds 3 pieces of info
id:
match:
1:

I'm trying to sort the results using ORDER BY match ASC but for some reason it's just not for having it...
Can't work out if it's an error with my php code or my table. I can order by "ID" no problem but I when I try ordering alphabetically by "match" it won't.

my code is:

Code: [Select]
mysql_connect("***.***.***") or die(mysql_error());
mysql_select_db("database") or die(mysql_error());


$query = "SELECT * FROM employees WHERE flag = 'tv' ORDER BY match ASC";
$result = mysql_query($query) or die ("Query failed");

$numrows = (mysql_num_rows ($result));


       

// loop to create rows
if($numrows >0){
echo "<table width = 100% border = '0' cellspacing = '2' cellpadding = '0' >";
// loop to create columns
$position = 1;
while ($row = mysql_fetch_array($result)){
if($position == 1){echo "<tr>";}
 
echo " <td align = 'center'><a href=\"http://www.website.eu/sport-stream/1/{$row['id']}.html\" target=_blank>{$row['match']}
<br>
<img src=\"{$row['8']}\" width=\"100\" height=\"70\" /> </a>
</td>

";
if($position == 4){echo "</tr> "; $position = 1;}else{ $position++;}
}//while

$end = "";
if($position != 1){
for($z=(4-$position); $z>0 ; $z--){
$end .= "<td></td>";
}
$end .= "</tr>";
}

echo $end."</table> ";
}//if
And here's a cap of my database:


any help for a php n00b would be greatly appreciated!

I got this code from a previous thread:

Code: [Select]
mysql_query("SET @rows = 0;");
$res = mysql_query("SELECT @rows:=@rows+1 AS view_rank,COUNT(id) AS views, credit_members_id FROM vtp_tracking GROUP BY credit_members_id ORDER BY views DESC");
$n   = array(1 => 'st', 2 => 'nd', 3 => 'rd');
while($row = mysql_fetch_row($res))
{
   if ( $row[2] != $members_id )
      continue;
   if ( substr($row[0], -1) < 4 )
   {
      $row[0] .= $n[$row[0]];
   }
   else
   {
      $row[0] .= 'th';
   }
   echo ' You are in ' . $row[0] . ' place with ' . number_format($row[1]) . ' views.';
   break;
}
Everything seems ok except it orders by the "credit_members_id" and not "views" as entered.

Can someone explain why, and how to fix this?

I need to make 0, which displays as POA appear at the ned of the list not at the begining, I currently just use
order by price asc

and 0 is at the beginning, i need to make 0 at the end

Currently i have a query which at the end has this
Code: [Select]
order by (value/counter) desc");

which works fine, however i was wondering, if in the case that 2 rows have the same, is it possible to set a second value to order by?

I have a database of assorted.  Each row contains defined QUANTITIES for each column item.
Example: columns for shirt, tie, pants, socks.
A row would indicate a purchase of 2 shirts, 1 tie, 0 pants, 3 socks for customer A.
Followed by a row indicate a purchase of 1 shirts, 1 tie, 4 pants, 2 socks for customer B, etc.

Now I want to sort EACH item, group them by quantity, and get an ordered list by quantity, that provides me with something like this:

1 shirt customer B
2 shirt customer C
3 shirt customer F
3 shirt customer H
4 shirt customer D, etc.

I am using this code for my query:
$query = "SELECT brisket, COUNT(brisket) FROM pass GROUP BY brisket ORDER BY brisket ASC";

but it is not organizing the info in a correlated manner.

Help?

I'm just trying to see if the order of my logic is correct or if there's something I can do differently.  I'm also curious to know at what point I should get the 2 passwords that exists in the database for the user. These are two different passwords.

Code: [Select]
function login_submit()
    {
        $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean');
$this->form_validation->set_rules('remember', 'Remember me', 'integer');
       
        $user_id = $this->users->get_user_id_by_username($this->input->post('username'));
       
        if ($user_id !== 0)
        {
            if ($this->kow_auth->is_max_login_attempts_exceeded($user_id))
            {
                echo json_encode(array('error' => 'yes', 'message' => 'Your account is currently locked, we appologize for the inconvienence. You must wait 10 minutes before you can login again!'));
            }
            else
            {
                $user_status = $this->users->get_user_status($user_id);
               
                if ($user_status == 1)
                {
                    echo json_encode(array('error' => 'yes', 'message' => 'Sorry you must verify your account before logging in!'));                   
                }
                elseif ($user_status == 3)
                {
                    echo json_encode(array('error' => 'yes', 'message' => 'Your account has been suspended!'));         
                }
                elseif ($user_status == 4)
                {
                    echo json_encode(array('error' => 'yes', 'message' => 'Your account is currently banned!'));         
                }
                elseif ($user_status == 5)
                {
                    echo json_encode(array('error' => 'yes', 'message' => 'Your account has been deleted!'));     
                }
                else
                {
                    if ($this->form_validation->run()) {
                        if ($this->kow_auth->login($this->form_validation->set_value('username'), $this->form_validation->set_value('password'), $this->form_validation->set_value('remember')))
                        {
                            redirect('');
        }
                        else
                        {
                            echo json_encode(array('error' => 'yes', 'message' => 'Incorrect username and password combination!'));
                        }
                    }
                }                                             
            }               
        }
        else

Hi All,

I have a 'Newspaper' in a game I'm coding. My plan was to have an edition every week and on average 15 articles a week. I would set this out like so. .

Code: [Select]
<?
$select_paper=mysql_query("SELECT * FROM paper WHERE id=1");
while($the=mysql_fetch_object($select_paper)){
?>
<table width=100% class=table>

<tr>
<td>
<td width=50% style=border: none; background-color: transparent; valign=top>


<table border=1 cellpadding=0 cellspacing=0 bordercolor=#000000 class='main' align=center>
<tr>
  <td width=500 class='tableheading'><?php echo "$the->title"; ?><center>
  </center></td>
  </tr>
<tr >
<td class="profilerow" align=left><center><?php echo "$the->news"; ?>
</td>
  </tr>
<tr >
<td  class="subtableheader" align=left><center><?php echo "Article By $the->by - $the->date"; ?>
</td>
  </tr>
  </table>
<br>
</td>
<? } ?>
With that repeated for 15 articles per edition.

BUT! To save time, space and complication, I would rather do it using something like this. .  Code: [Select]
$select = mysql_query("SELECT * FROM paper WHERE edition=1 ORDER by id ASC");
$num = mysql_num_rows($select);
Could someone tell me how to intergrate this with the layout tables as show in code #1?

Thanks!

Hi all,

I have a script that is essentially a log file of all preious versions of an article (versioning)

You can see the script I am talking about in action at:

http://danielrhyshardy.com/AWT/forumadmin.php

What I would like to do is, instead of displaying the title of each instance (you will see there are two instances named "apple", as they are two previous versions of an article), I would like to display that title once, and then all of the instances of that title be displayed below.

I hope that makes sense.

Here is the code Code: [Select]
<?

$sql = "SELECT id,title,message,date_added FROM messages2 ORDER BY id "; 
 
 
 
 
   $result = mysql_query($sql) or trigger_error(mysql_error(),E_USER_ERROR);
   
   



   while(list($id,$title,$message,$date_added)=mysql_fetch_row($result)){





     
echo '<div style="color:#bb0000;width:250px;text-align:center;float:left;margin-left:15px;margin-bottom:15px;padding-bottom:20px;"><b>'.$title.'<br>'.$date_added.'</b>
 
<input id="'.$message.'" type="radio" name="admin[]" value="'.$id.'"  onclick="javascript:document.form22.car.value=this.id"
  >


</font></div>'."\n";
   
   

   

 
}



?>

I would use something like
Code: [Select]
if ($title = "apple") {

but this would obviously not work for new posts, unless I wanted to constantly update my code.

I am sure there is a simple way to achieve this.

Perhaps someone can tell me!?

Thanks in advance

Dan
