PHP - Date_diff Function Not Accurate

the php web video script that I'm trying to modify allows Users to purchase videos successfully, however, the video price that is reflected in the db ('u_paid_videos') table (where transaction info is stored) appears to show the default video price (video_play_price from the 'config' db table) every time, instead of the accurate video price. I'm not sure if this code needs to be tweaked so that the actual price will show in the 'video_play_price' column (in 'u_paid_videos' table):

// get cost video // get the default video price, to use if there is no per video play price
	$db->where('name', 'video_play_price');
	$db_cost = $db->getOne('config');
	$video_cost = (float)$db_cost->value;

	// the number of submitted videos - used to determine if all records were inserted
	$count_video = count($id_array);
	$user_id = $user->id;

	$wallet = (float)str_replace(',', '', $user->wallet);
	$balance = (float)str_replace(',', '', $user->balance);

	// add up the video prices
	$amount = 0;
	foreach ($id_array as $id) {

	$video_id = (int)PT_Secure($id);

	// get video data
	$video = $db->where('id', $id)->getOne(T_VIDEOS);

	// add the video play price if any, or the default price
	$amount += $video->video_play_price?$video->video_play_price:$video_cost;
	}

	// determine if the user has enough credits
	if( ($wallet >= $amount) OR ($balance + $wallet >= $amount) ) {

		$db->startTransaction();

		$inserted_records = 0;
		foreach ($id_array as $id){

			$video_id = (int)PT_Secure($id);

			// get video data
			$video = $db->where('id', $id)->getOne(T_VIDEOS);

			// use the video play price if any, or the default price
			$video_cost_new = $video->video_play_price?$video->video_play_price:$video_cost;

			$uploader_amount = $video_cost_new *0.50;

			// add data to paid table
			$insert_buy = $db->insert('u_paid_videos', [
				'id_user' => $user_id,
				'id_video' => $video_id,
				'session_key' => $_SESSION['session_key'],
				'video_play_price' => (string)$video_cost,
				'video_title' => $video->title, 
				'user_id_uploaded' => $video->user_id, 
				'earned_amount' => $uploader_amount
				]);

 

 

 

 

 

On my search result page, I wanted to search for "Nintendo DS Lite - Pink"

I used following code:

Ex:
Code: [Select]
$search_text = "Nintendo DS Lite Pink";

$kt=split(" ",$search_text);//Breaking the string to array of words

// Now let us generate the sql
while(list($key,$val)=each($kt))
{
if($val<>" " and strlen($val) > 0)
{
$q .= " name like '%$val%' or ";
}
}// end of while

//Remove the last 'OR'
$q=substr($q,0,(strlen($q)-3));



Than the $q would be:
Code: [Select]
SELECT * FROM `products`
WHERE 
name like '%Nintendo%' or 
name like '%DS%' or 
name like '%Lite%' or 
name like '%Pink%'


And i am getting Mysql Output given below:


1) Activity Meter - DS.
2) Nintendo DS Red.
3) Nintendo DS Lite Pink.
4) Nintendo DS Lite Turquoise.

But the third result is most accurate/relevant then first two result.

Please help me out to get the most accurate row first then the relevant rows as per their relevancy with search term "$search_text"

Many Thanks  in Advance.

Hello all, I have some piece of code that is nested like this


$variable = 'This is a global argument';
function parentFunction($variable) {
function childFunction() {
echo 'Argument of the parent function is '.$GLOBALS['variable'];
}
childFunction();
}
parentFunction(5);


What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot .

Thanks in advance

Question 1) Is the only and proper way to call a parent function "parent::function()"?  Are there other/better ways from within a child function?

Question 2) What are the deciding factors for when to make a function or attribute static?  How do you make that decision?  Assuming 5.3...

Thanks.

I need to call usort from a class function, and I'm puzzled about how to define the comparison function.

I've tried to define the comparison function in the same class, but I can't get usort to call it. I found one hint that it will work if I make the comparison function static, but I tried that, and it didn't work for me.

If I define the comparison function outside the class, it won't have access to object properties that it needs to operate.

The only solution I can think of is to define the comparison function outside the class and put the object properties it needs in globals. Is there a cleaner way to do this?

I have this function completely written in my class file that I am working on.  The point to this function is to be able to check the login of a user or administrator for either of the control panels associated with my site.

It will check the session intime as well as the page / module referenced.  Once it passes all those checks, it will check and ensure the emailaddress/password stored in the current session still holds true and the account is still active...  if the account is still active it will update the lastActivity as well as update all of the session variables with what is currently in the database.

What I am looking for is basically a look at the function, see if it looks good..  If there is any part to it that could create security holes for the site just off the login function itself...

Usage: $q->validUser($_SESSION['user'], $_mod);

<?php
 function validUser($sess, $p) {

if ($sess['inTime'] == '' && $p != 'login' && $p != 'logout') {
session_destroy();
$login = '0';
$_int = '';
return $login;
} else if ($sess['inTime'] < time()-3600 && $p != 'login') {
$sess['inTime'] = '';
session_destroy();
$this->check_login($sess, $p);
} else {
$this->user = $sess['emailAddress'];
$this->pass = $sess['password'];

$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
   AND status = '1' LIMIT '1'");
if ($login = $this->sql_numrows($login) < 1) {
$sess['inTime'] == '';
session_destroy();
$login = '0';
} else {
// logged in, lets update the database for last_activity AND the session.

$this->sql_query("UDATE users SET lastActivity = '".now()."' WHERE
  emailAddress = '".$this->user."'");
$login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' 
       AND status = '1' LIMIT '1'");
$login = mysql_fetch_assoc($login);
foreach ($login as $key => $value)
{ 
$sess[$key] = $value;
}
$sess['inTime'] = time();
$login = '1';
}
return $login;
}
}

?>

That is the main function, sql_query and sql_numrows is:

<?php
function sql_query($query = "", $transaction = FALSE) {
unset($this->query_result);

if ($query != "") {
$this->num_queries++;
if ($transation == BEGIN_TRANSACTION && !$this->in_transation) {
$result = mysql_query("BEGIN", $this->db_connect_id);
if (!$result) {
return false;
}
$this->in_transaction = TRUE;
}

$this->query_result = mysql_query($query, $this->db_connect_id);
} else {
if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$result = mysql_query("COMMIT", $this->db_connect_id);
}
}
if ($this->query_result) {
unset($this->row[$this->query_result]);
unset($this->rowset[$this->query_result]);

if ($transaction == END_TRANSACTION && $this->in_transaction ) {
$this->in_transaction = FALSE;
if (!mysql_query("COMMIT", $this->db_connect_id)) {
mysql_query("ROLLBACK", $this->db_connect_id);
return false;
}
}
return $this->query_result;
} else {
if ($this->in_transaction ) {
mysql_query("ROLLBACK", $this->db_connect_id);
$this->in_transaction = FALSE;
}
return false;
}
}

function sql_numrows($query_id = 0) {
if(!$query_id) {
$query_id = $this->query_result;
}
return ($query_id) ? mysql_num_rows($query_id) : false;
} ?>

Any insight that can help to benefit these functions would be appreciated.

I want to define a function instead of repeating query in all my php pages. I call a function by passing an $id value and from that function i have to get all the info related to that id, like name, description and uom.    I am trying to do this, but i dont know how to get these values seperately.   here is my function  

function items($item_id)
{
$details = array(); 
$result = mysql_query("select item_id, name, uom, description from items where item_id=".$item_id."") or die (mysql_error());
while($row = mysql_fetch_array($result))
{
$details[] = array((stripslashes($row['name'])), (stripslashes($row['uom'])), (stripslashes($row['description'])));
}
return $details;
}

and i call my function like this

$info = items($id);

Can somebody guide me in this    

When I put this chunk of code into it's own function:


function fetch_all ($dbc, $query) {

include ('knuffix_list_func.php');

pagination_start ($dbc, $query);

$offset = $pag_array[0];

$rows_per_page = $pag_array[1];

$query = $query . " LIMIT $offset, $rows_per_page";

echo "test query: " . $query;

knuffix_list ($query, $dbc);

pagination_end ($pag_array);
}


And when I echo out the query as you can see in the example, then I notice that the variables $offset and $rows_per_page never get appended.
I set the variable $pag_array to a global inside the function pagination_start(). It usually works when I DON'T wrap a function around this chunk of code, but if I do wrap a function around everything then the global suddenly won't work anymore.

Btw, this also won't work if I wrap a function around the function DECLARATIONS.

Any ideas, how I could make it work?

im using a function which connects to a db called 'comments' and then inside that function i again called another function that will connect to the db 'main' to get avatars.... but as i put Code: [Select]
mysql_select_db("main") or die(mysql_error()); on the new function, the original function stops to fetch rows.

i tried to remove "mysql_select_db("main") or die(mysql_error());" and used the new function to return some text only and it worked, so i guess the connection to the db was the problem... i tried doing Code: [Select]
mysql_query("SELECT * FROM  main.avatar
INNER JOIN main.list ON main.avatar.title=main.list.id
WHERE main.avatar.page_id='$id'"); but it also didnt work

I've followed the PHP Freaks pagination tutorial which you can find here.

And I also got it to work, the only problem is that the script won't work when I use the query outside of the function.

Here's the function:



<?php

$row = mysqli_fetch_row($query_run);
$num_rows = $row[0];

// number of rows to show per page
$rows_per_page = 5;

// find total pages -> ceil for rounding up
$total_pages = ceil($num_rows / $rows_per_page);

// get the current page or set a default
if (isset($_GET['current_page']) && is_numeric($_GET['current_page'])) {

// make it an INT if it isn't

$current_page = (int) $_GET['current_page'];

} else {

// default page number

$current_page = 1;

}


// if current page is greater than total pages then set current page to last page

}

As you can see above, the script will only work if I put the query right below the $offset variable and above the $data variable.

I put the test echo above the query to see how the query looks like when I induce the query from the outside through the function parenthesis into the function, and this is what I get printed out:


test SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contributed_date DESC LIMIT ,


Obviously the $offset and the $rows_per_page variables are not set, when I induce the query from the outside into the function.

So in that sense my question is:

How can I induce the query from the outside into the function SO THAT the $offset and the $rows_per_page variables are set as well and NOT empty?


p.s.

I need the query outside of the function because I'm using a sort by category functionality.

Hi I have a table class and functions I want to call in another function but can't get it working. Some help will be very welcome.

It seesm that the new table class is not working in this function if I pass the values to it, I have tested the class, it does get the post values I post to it so $_POST['id'] are being received as well as all the other $_POST's but the table class and find function is not working, it works fine if I don't put it in a function..

function edit() {
   
   if (isset($error)){ $error.="Please fix the error(s) above";}
   else {

      if ($_POST['id'] <> "") { 
                   
         $update =& new table($db, 'publisher');

         $update->find($_POST['id']);
         $update->name       = $_POST['name'];
         $update->url        = $_POST['url'];
         $update->contact    = $_POST['contact'];
         $update->address    = $_POST['address'];
         $update->phone        = $_POST['phone'];
         $update->email        = $_POST['email'];
         $update->save();

         $error = "The Publisher has been edited";   
                }
   }
  }

Hi all, I want to call a javascript function from a php function like this:

        public function Buscar()
        {
            $HoraInicio = $_POST['edtHoraInicio'];
            $HoraFin = $_POST['edtHoraFin'];
            $FechaInicio = $_POST['edtFec1'];
            $FechaFin = $_POST['edtFec2'];

            $FechaMax = $FechaFin." ".$HoraFin.":00";
            $FechaMin = $FechaInicio." ".$HoraInicio.":00";

            $_GET["FechaMax"] = $FechaMax;
            $_GET["FechaMin"] = $FechaMin;

            echo $FechaMin;

            echo "<script language=javascript>alert('Hi.')</script>";
           
        }

but the function Buscar never show the alert but shows the $FechaMin

I hopu u guys can help me out with this probem

Thanks,

Siddhartha

can you do that with php?

Code: [Select]
Database2() {
function test($id) {

$newdb = new Database2();
$newdb->test($id);


}
}

window.setInterval(function(){

s="<?= $lastid ?>";

$.post('../action/updatestream.php',{statusid:s.val()},function(e){
 
alert(e)

 });


}, 10000);

Why isn't it working?

Thanks,  

Hello Everyone
