PHP - Hitting Back On A Broswer Is Affecting My Php Code

pls help me..
i am new to PHP unit testing concept. i just wrote a PHP unit test case for a login module in ZEND frame work. for that we have to see the result via command promt. but in some places of zend frame work we are using '$_SERVER['HTTP_HOST']' to get server host name but it can get only by hitting via browser so while am hitting via command promt it will give error message lik this(given below)

Generating code coverage report, this may take a moment.PHP Notice:  Undefined index:  HTTP_HOST in /opt/coolstack/apache2/htdocs/LPS/application/bootstrap/Bootstrap.php on line 147

Notice: Undefined index:  HTTP_HOST in /opt/coolstack/apache2/htdocs/LPS/application/bootstrap/Bootstrap.php on line 147

"BACK" or REFRESH: Preventing database interaction / code execution
how to prevent database interaction / code execution when user presses back or refresh button?
can i detect?
can i disable back/refresh?

Hi,


I have set up 2 php pages

page 1 - add_entry2.php
In this page I have a invoice table created where I can dynamically add/delete rows. This has a View Bill button which takes me to page 2- add_entry3.php
In this page it shows up the rows added in page 1 in read only format, so if the user wants to modify the data that he/she entered then he must Click on <back> that i have provided in the page 2 which will direct him to page 1

Now the problem starts here
on click of Back the dynamically added rows dissappear..which is frustrating..I know its something to do with my code..but can anyone help me fix it.

One more thing is that i dont want to store the data into DB till the finalise button is clicked on page 2 so that means till page 2 is submitted nothing goes to DB from Page 1. 


I am able to retain values if I use the code Code: [Select]
<form action="add_entry2.php" name="eval_edit" method="post" format="html">
i,e if I submit back to the same page and retrieve values form $_POST


but If I use the code Code: [Select]
<input type="button" value="Back" onClick="history.go(-1);return true;">to get back to add_entry2.ph it looses all the values. Is there any other way to code the BACK link retaining my $_POST values(Do you think $_SESSION would work in this case?)

I tried to google it but i'm not quite sure how to formulate the proper phrase to express what i'm looking to do.

What i'm trying to accomplish is cropping an image without chopping away any bits of the content within that image. For example, imagine you have a square image the size 1000px by 1000px canvas and within that canvas is a photo of an object that's roughly 400px BY 750px.

I would like to crop the 1000x1000 canvas to be within 5 pixels of the longest side of the content image, so in this case i'd like to crop it to a 755x755 squared pixel image.

So i guess the main question is how can i check for the content on a canvas which btw may not always be white, but might be other colors and of other things in the background. I understand some things may make it impossible, but let's just for now assume the canvas is always white.

Thanks!

i am printing the dates from the last 30 days in ascending order and then comparing them in my query to print the results. How can I can print the below array in descending order without affecting my query?
Code: [Select]
   
  $thirtydaysago = time() - (30 * 24 * 60 * 60);
 
  $oneday=24 * 60 * 60;
  for($i=0;$i<31;$i++)
  {
     $d[$i]= $thirtydaysago + ($i*$oneday);
echo date('Y-m-d',$d[$i])."<br>";
  }
  for($i=0;$i<31;$i++)
  {
     $postsql=mysql_query("SELECT DATE_FORMAT(FROM_UNIXTIME(dateline), '%Y-%m-%d') AS FmtDate, COUNT(postid) AS PostCnt FROM post " .
              "WHERE dateline < '" . $d[$i+1] . "' AND dateline >= '" . $d[$i] . "' GROUP BY DATE_FORMAT(FROM_UNIXTIME(dateline), '%Y-%m-%d') DESC") or die(mysql_error());
   

   if($postsql_rows=mysql_fetch_assoc($postsql))
   {
    $data_date[$i]["date"]=$postsql_rows['FmtDate'];
$data_postcount[$k][$i]["postcount"]=$postsql_rows['PostCnt'];
   }
 }
 $k++;
 }

Hello everyone! I am a new user and I have a simple question. How to download the database and create a backup. 

And we're back online... again!  It may have taken 3-4 days, but we're back.

I made a file for updating data.
I do get the id back from the view page, but not the variable.

Hey everyone. So lately I've been searching for someone to do this for me but I figure if I learned it myself it'd be much more helpful to me in the future. I run a gaming clan, and we have a roster. You can view it he  http://www.zealotgam...s.php?pageid=15

Obviously, you can see a few things. The default page lists all our staff. That is very easy, and not really the part I need help with. The help begins with the games list you see at the side. When you click a game, it lists all users who have that Game listed as their Main Game in a profile field, and lists other info, such as their rank, In-Game contact (which is another profile field) and join date/last active. The games are also themselves divided into categories.

Our code is relatively simple. We keep a manual array of info that keeps these together you can see below:
 

 

// Define Games and Lists //
$gameslist = array();
        
//SETUP $gamelist[] = array("Game Name","urlshortcode","Name of In-Game Name or Account", "field# for that profile field");
        
$gameslist[] = array("Battlefield 4 (PS4)", "bf4ps4", "PlayStation ID", "field7");
$gameslist[] = array("Counter Strike: Global Offensive (EU)", "csgoeu", "Steam ID", "field8");
$gameslist[] = array("Counter Strike: Global Offensive (NA)", "csgona", "Steam ID", "field8");
$gameslist[] = array("Elder Scrolls Online (NA)", "esona", "Main Character", "field45");
$gameslist[] = array("League of Legends (EUNE)", "loleune", "Summoner Name", "field12");
$gameslist[] = array("League of Legends (EUW)", "loleuw", "Summoner Name", "field31");
$gameslist[] = array("League of Legends (NA)", "lolna", "Summoner Name", "field32");
$gameslist[] = array("League of Legends (OCE)", "loloce", "Summoner Name", "field47");
$gameslist[] = array("Minecraft", "mc", "Username", "field14");
$gameslist[] = array("Smite (EU)", "smiteeu", "Smite Account", "field22");
$gameslist[] = array("Smite (NA)", "smitena", "Smite Account", "field22");
$gameslist[] = array("Titanfall", "tfall", "Origin ID", "field29");
$gameslist[] = array("WildStar (EU)", "wseu", "Main Character", "field48");
$gameslist[] = array("WildStar (NA)", "wsna", "Main Character", "field48");
$gameslist[] = array("World of Tanks (EU)", "woteu", "WarGaming.NET ID", "field46");
$gameslist[] = array("Other Game", "other", "", "");


// Game Type Categories
$gamecats = array();


// ADD the # of the game in the list above (starting from 0) to the appropriate category array number list.
$gamecats[] = array("Divisions",array(4,5,6));
$gamecats[] = array("Guilds",array());
$gamecats[] = array("Gaming Groups",array());
$gamecats[] = array("Divisions in Development",array(0,1,2,3,7,8,9,10,11,12,13,14));
$gamecats[] = array("Miscellaneous",array(15));

 

This gets tedious to keep track of manually, and my admins with no programming experience can barely understand what is happening.

The listing of users is very easy, and I do not need any help with that. What I would like to add is a manager in the admin panel where you could save the information listed above to a table such as PREFIX.games. I imagine having several drop down boxes. A mockup is below:
 

 
I'd then Like a list of games that includes these rows in the table with a [ ] Remove checkbox.

I do not know how to add this to the admin panel and would love guidance on how to begin doing this. The sorting would go by Game Status (the second array in my php code) then Alphabetical. This would go a long way in helping my staff edit this list themselves. Any help would be appreciated.

Skype: j.c.will my be better to work personally with me.

I have the following code. Before back button was working. Now don't understand what happend but when I click Back button I receive "Webpage has expired" window in my browser. What may be the reason?

Perhaps a simple task...  I did ASP coding before, now I'm into PHP. So I'm a newbie in PHP.

2 arrays : $array1 = array("1","2","3","4");  and    $array2 = array("1","2");

In array2 you'll find the numbers that need to be excluded from array1.   So I should have als result  3 and 4.

I tried since 2 days now and can only check and exclude  1 number from array2  butnot dynamical !

Code: [Select]
$ii = 1;
foreach( $arrayLordervalue as $value )
{
  if( $value  == 1 )continue;
 

//komma's tussen de cijfers plaatsen
if($ii == 1){ $values[$ii] = $value;}
else { $values[$ii] = ",". $value;  }
$value2= $value2.$values[$ii];
$ii++;   
}

echo  $value2;     

Gives me 2,3,4. 

I'm completely stuck !

I tried foreach, for ($n...),while... bah what's left ? 

Hi guys,

     I am starting out on mvc, I been reading up on it for a bit now.. and I was just wondering if anyone can take a quick look at it and
give me some insight on it? maybe some suggestions etc.. I will be using this for a some what medium site when I know that it is good enough to be published. Note that its not done.. in reality I just need to make sure I am heading in the right direction.

I have tried to create a back button, but I have not reached the correct solution.
I log into first page (index.php) and then you will get two new buttons that brings me to two different pages. Then I want to come back to the login page, the session is gone and I have to log in again. I want to remain logged in  when I get to the index page and be able to see the two buttons. I tried different things such as:

Code: [Select]
<input type="button" value="Return to previous page" onClick="javascript:history.go(-1)" /> Code: [Select]
<?php $referer = $_SERVER['HTTP_REFERER'];
   if (!$referer == '') {
      echo '<p><a href="' . $referer . '" title="Return to the previous page">&laquo; Go back</a></p>';
   } else {
      echo '<p><a href="javascript:history.go(-1)" title="Return to the previous page">&laquo; Go back</a></p>';
   }
?>
But that's not what I'm thinking about. How can I solve this?
