PHP - About Registering Globals...
Well I heard that registering $GLOBALS is a bad practice in general since their values can be changed by anyone at anytime. However, the usage of $GLOBALS does simplify the script considerably at times when a certain column in a table needs to be retrieved repeatedly. A good example is user's money data stored in table prefix_users as shown below:
Code: [Select] $result = mysql_query( "SELECT * FROM {$prefix}users WHERE uid = '$uid'"); $GLOBALS['usersettings'] = mysql_fetch_array($result); $GLOBALS['money'] = $GLOBALS['usersettings']['money']; If the above code is included in a function file, it will be possible to simply use $GLOBALS['money'] to retrieve user's money data without having to write lines of mysql commands everytime. So I was wondering, is there another way to retrieve database info from a certain column easily but not to register $GLOBALS? Just curious. Similar TutorialsI have a form where members on my site can update their display name among other things. However, my script is returning the error for if nothing was inputted in the display name input box (members must provide a display name, can't leave that box blank) even though my text input box definitely has a value. The section of my form with the input box: Code: [Select] <tr> <td class='sidebardark' width=40%><b>Display Name</td> <td class='D' width=60%><input type=text name=newdisplayname class='inputtext' value="<? echo $currentname;?>"></td> </tr> And the section in my form-submitted script that has the error that's displaying: Code: [Select] $newdisplay = strip_tags(mysql_real_escape_string($POST['newdisplayname'])); if ($newdisplay == "" || !isset($POST['newdisplayname'])){ errorbox("You must set a display name!"); } Normally I'd think it was a typo on my part but I honestly can't see anything wrong with it. The current display name is showing up just fine in the input box. I asked it to echo $newdisplay above the error box and it echoed nothing so I have to assume it's not passing the variable correctly for some reason. Edit: If it matters, I haven't had any issues with text input boxes on this particular site before. Only this specific one. Hi, I have a site where users can register etc. I was wondering should I use mysql_real_escape_string() for the elements on my registration form example email, name and so on or is it no necessary? One more question could some one tell is this the proper way to use it before inserting into the database. $name=$_POST['name']; mysql_real_escape_string($name) ? Hi there I would be most grateful is someone could tell me why my data is not being entered into my database and not responding with an email confirmation link.

If there are any problems here an error is added to the $messages array and then the script executes the 'doIndex()' function - this function basically outputs the main 'index' page for this script - ie the login form.

If nothing is returned from the 'checkPass()' function, an error is added to the $messages array and the 'doIndex()' function is called as above.

Same for zip code/postal code...american zip code would be like 90210 where as a postal code would be like n5j2S1. Is there a script or something already I can use with all the countrys/provinces/states etc already entered so im not re-inventing the wheel here? If someone can point me in right directon id appreciate it. Thanks Has anyone encountered this bug which had me banging my head against the desk all morning? In the beginning I registered a $GLOBALS['direction'] that equalled to a radio button value. Later in the script I declare a variable $direction that for some strange reason took the value of $GLOBALS['direction'] without me even writing so. So when i compared them they had the same value. As soon as I changed $direction to $directionx the script worked and the value wasn't "copied" to the $GLOBALS. What's up? Almost every time when I read about globals, programmers discourage their use. I have a function where I need to send back some variables (which I will use in a query) so I need to use globals. Below is the function and query. I'm trying to figure out if it's ok to use globals in it. function paginate($connection, $tableName) { //the forsaken globals global $limit; global $start; //Pagination $targetpage = "http://localhost/website/untitled2.php"; $limit = 4; //count rows $sql = "SELECT COUNT(*) as num FROM $tableName"; $total_pages = $connection->query($sql) or die(mysqli_error($connection)); $row = $total_pages->fetch_assoc(); $total_pages = $row['num']; //if there's no page number, set it to the first page $stages = 3; $page = isset($_GET['page']) ? $_GET['page'] : 0; $start = empty($page) ? 0 : ($page - 1) * $limit; // Initial page num setup if ($page == 0){$page = 1;} $prev = $page - 1; $next = $page + 1; $lastpage = ceil($total_pages/$limit); $LastPagem1 = $lastpage - 1; $paginate = ''; if($lastpage > 1) { $paginate .= "<div class='paginate'>"; // Previous if ($page > 1){ $paginate.= "<a href='$targetpage?page=$prev'>previous</a>"; }else{ $paginate.= "<span class='disabled'>previous</span>"; } // Pages if ($lastpage < 7 + ($stages * 2)) // Not enough pages to breaking it up { for ($counter = 1; $counter <= $lastpage; $counter++) { if ($counter == $page){ $paginate.= "<span class='current'>$counter</span>"; }else{ $paginate.= "<a href='$targetpage?page=$counter'>$counter</a>";} } } elseif($lastpage > 5 + ($stages * 2)) // Enough pages to hide a few? { // Beginning only hide later pages if($page < 1 + ($stages * 2)) { for ($counter = 1; $counter < 4 + ($stages * 2); $counter++) { if ($counter == $page){ $paginate.= "<span class='current'>$counter</span>"; }else{ $paginate.= "<a href='$targetpage?page=$counter'>$counter</a>";} } $paginate.= "..."; $paginate.= "<a href='$targetpage?page=$LastPagem1'>$LastPagem1</a>"; $paginate.= "<a href='$targetpage?page=$lastpage'>$lastpage</a>"; } // Middle hide some front and some back elseif($lastpage - ($stages * 2) > $page && $page > ($stages * 2)) { $paginate.= "<a href='$targetpage?page=1'>1</a>"; $paginate.= "<a href='$targetpage?page=2'>2</a>"; $paginate.= "..."; for ($counter = $page - $stages; $counter <= $page + $stages; $counter++) { if ($counter == $page){ $paginate.= "<span class='current'>$counter</span>"; }else{ $paginate.= "<a href='$targetpage?page=$counter'>$counter</a>";} } $paginate.= "..."; $paginate.= "<a href='$targetpage?page=$LastPagem1'>$LastPagem1</a>"; $paginate.= "<a href='$targetpage?page=$lastpage'>$lastpage</a>"; } // End only hide early pages else { $paginate.= "<a href='$targetpage?page=1'>1</a>"; $paginate.= "<a href='$targetpage?page=2'>2</a>"; $paginate.= "..."; for ($counter = $lastpage - (2 + ($stages * 2)); $counter <= $lastpage; $counter++) { if ($counter == $page){ $paginate.= "<span class='current'>$counter</span>"; }else{ $paginate.= "<a href='$targetpage?page=$counter'>$counter</a>";} } } } // Next if ($page < $counter - 1){ $paginate.= "<a href='$targetpage?page=$next'>next</a>"; }else{ $paginate.= "<span class='disabled'>next</span>"; } $paginate.= "</div>"; } echo $total_pages.' Results'; // pagination echo $paginate; }//end function and this is how I'm using the function. Without the globals I would get undefined vars $start and $limit used in the query below. paginate($connection, "categories"); $sql = "SELECT * FROM categories ORDER BY cat_name LIMIT $start, $limit"; $cats_result = $connection->query($sql) or die(mysqli_error($connection)); while ($row = $cats_result->fetch_assoc()) { $cat_id = $row['cat_id']; $cat_name = $row['cat_name']; $cat_desc = $row['cat_desc']; ...etc Am I using the globals properly? What does this mean? Code: [Select] {$GLOBALS['path']} Hey guys, Just lately I have been trying to start a specific project for myself. I started off by designing the pages etc on HTML, and then a friend of mine helped me convert them to PHP.
At the moment, when a user registers to the site, they only require to enter a Username and Password. I would like to add their email to it too, due to adding slightly extra security. It would also be used for future reasons such as sending emails out etc.
I'm not sure about adding this, I know that most likely it is going to be VERY similar to how it already is, but I couldn't seem to get it to work when I tried.
Ill give the coding which I am using for this below (the documents which I believe would need editing) :

Edited by Lewis2212, 06 August 2014 - 10:20 AM. I WANT TO MAKE AN ARRAY LIKE $GLOBALS structu if you run var_dump($GLOBALS): you will see that this is an array and contains another 9 array with key names. when there is a value(name) in "_POST" you cant use echo $GLOBALS["name"]. but when there is a value("fname") in "GLOBALS" you can use echo $GLOBALS["fname"]. how this array works like that? and how to make an array that behave like that? Edited January 17, 2020 by Silent-BHi I'm currently experiencing problems with my super global outputs.
I'm using
$_SERVER['HTTP_X_MXIT_NICK']; I'm learning functions and I'm working on a rating script. This is a small test script that works, you can try it out yourself: <?php // Rating System function while_test (){ $a = 1; $b = 4; $t_id = 1; global $likes; global $dislikes; global $con_id; while ($a++ <= $b){ echo "<center>"; echo "<table><tr><td>Table: </td></tr>"; echo "<tr><td>This is a table test </td></tr>"; echo "<tr><td><form action='' method='post'>"; echo "<button type='submit' name='likes' value='Y'>likes</button>"; echo "<button type='submit' name='dislikes' value='N'>dislikes</button>"; echo "<input type='hidden' name='hidden_id' value='" . $t_id . "' /></form></td></tr></table>"; echo "</center><br /><br />"; $t_id++; $likes = $_POST['likes']; $dislikes = $_POST['dislikes']; $con_id = $_POST['hidden_id']; } } while_test(); if ($likes) { echo "likes it: " . $likes . " con_id: " . $con_id; } elseif ($dislikes) { echo "dislikes it: " . $dislikes . " con_id: " . $con_id; } ?> I've gotten recommended before not use globals, because the projects would become unmanageable, and I'm wondering how would I be able to avoid using globals in this example? I'm able to in-ject variables through the parenthesis, but I'm not able to out-ject variables, if that makes sense. (?) At least it doesn't work for me. How would I use those three variables $likes, $dislikes and $con_id outside the function without setting them as globals, what would be good practice? This topic has been moved to Application Design. http://www.phpfreaks.com/forums/index.php?topic=356029.0 Learning something new here so if anyone can tell me why I this wont return a value? page1.php Code: [Select] <?php require "page2.php"; getuserid(); echo $userID; ?> page2.php Code: [Select] <?php function getuserid() { $user =& JFactory::getUser(); $userID = $user->id; global $userID; } ?> I have been trying to better understand how php works on a more in depth level, and recently I have been tinkering with arrays. Using print_r() I have been studying the $GLOBAL array, and I found something I can't seem to find an explanation for. In my $GLOBALS array there are variables I have set in a configuration file, but never actually made into globals. Take the following code, and its output for example. echo "<pre>"; echo print_r($GLOBALS); echo "</pre>"; The output: Code: [Select] Array ( [GLOBALS] => Array *RECURSION* [_POST] => Array ( ) [_GET] => Array ( ) [_COOKIE] => Array ( [PHPSESSID] => fai4rtfgdt6o6iaihh62d0pa15 ) [_FILES] => Array ( ) [_SERVER] => Array ( [HTTP_HOST] => DOMAIN [HTTP_USER_AGENT] => Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10 [HTTP_ACCEPT] => text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 [HTTP_ACCEPT_LANGUAGE] => en-us,en;q=0.5 [HTTP_ACCEPT_ENCODING] => gzip,deflate [HTTP_ACCEPT_CHARSET] => ISO-8859-1,utf-8;q=0.7,*;q=0.7 [HTTP_KEEP_ALIVE] => 115 [HTTP_CONNECTION] => keep-alive [HTTP_REFERER] => http://DOMAIN/test.php [HTTP_COOKIE] => PHPSESSID=fai4rtfgdt6o6iaihh62d0pa15 [HTTP_CACHE_CONTROL] => max-age=0 [CONTENT_TYPE] => application/x-www-form-urlencoded [CONTENT_LENGTH] => 67 [PATH] => /sbin:/usr/sbin:/bin:/usr/bin [SERVER_SIGNATURE] => [SERVER_SOFTWARE] => Apache [SERVER_NAME] => DOMAIN [SERVER_ADDR] => IPADDRESS [SERVER_PORT] => 80 [REMOTE_ADDR] => 198.65.168.24 [DOCUMENT_ROOT] => /home/USER/www/DOMAIN [SERVER_ADMIN] => webmaster@DOMAIN [SCRIPT_FILENAME] => /home/USER/www/DOMAIN/test.php [REMOTE_PORT] => 43272 [GATEWAY_INTERFACE] => CGI/1.1 [SERVER_PROTOCOL] => HTTP/1.1 [REQUEST_METHOD] => POST [QUERY_STRING] => [REQUEST_URI] => /test.php [SCRIPT_NAME] => /test.php [PHP_SELF] => /test.php [REQUEST_TIME] => 1286050077 ) [date] => October 2, 2010 [db_date] => 10/02/2010 [error] => Array ( ) ) 1 The 3 items at the bottom. Code: [Select] [date] => October 2, 2010 [db_date] => 10/02/2010 [error] => Array Were set inside of a php config file. My question is, how did they end up in the $GLOBALS array? I am using a MVC framework and in my controller I have defined a class variable for configurations. In my action I have a call to the configuration class to set the class variable to the current configurations. Code: [Select] public $configArray = array(); public function actionBuild($id) { $this->configArray=Config::model()->getConfigArray($id); $this->buildStep1(); ... } When I echo the configuration in the method it is 10 but when I echo in buildStep1 it is 11. What is the proper way for configArray to be global and updated when I call getConfigArray for use in functions in the class? I just want to know how to create a global variable from within a function. The reason I want to do this is I'm making mysql queries that may or may not have data in a function, if the data does indeed exist, I want to declare variables at that point. My queries are grouped logically by year/month, and as a result I'm going to be appending data to existing variables if they exist so it makes more sense to just append it to what would be the global variable anyways instead of just passing large strings out of the function to just be appended anyways -- plus it prevents me from creating a bunch of pointless variables. I intend additionally take the variables created inside the function and then store them in an encompassing global array (pre-defined outside of function) and at the end of the script do a foreach through it so I can iterate through the variables to grab my data knowing that there won't be pointless crap in there. I'm trying to create global variables by using variable variables ($$whichever). The code giving me issues inside the function is just like this: Code: [Select] function SeekAndAppend ($vars, $being, $passed) { global $$whatever; // Trying to define it here global $array; // Calling predefined $array $array[] = "$$whatever"; // Passing just created global to the array for iteration later } When I iterate through the array the expected name of what would be the global variable name is there, but the global variable itself does not exist -- just at the function level. If someone has a recommendation on a better way to do it, I'll listen, but please don't turn it into a lecture. EDIT: Grammar & Clarity HI! Can someone explain the variables $value and $key that are being produced at the end of the output by the following code. It seems like the foreach loop is creating two extra variables. <?php $test_1 = "matt"; $test_2 = "kim"; $test_3 = "jessica"; $test_4 = "keri"; foreach ($GLOBALS as $key => $value) { echo $key . "- - -" . $value; echo "<br />"; } ?> Output GLOBALS- - -Array _POST- - -Array _GET- - -Array _COOKIE- - -Array _FILES- - -Array test_1- - -matt test_2- - -kim test_3- - -jessica test_4- - -keri value- - -keri key- - -value Thanks! steadythecourse In the following code, Code: [Select] // Register Globals if (ini_get('register_globals')) { ini_set('session.use_cookies', 'On'); ini_set('session.use_trans_sid', 'Off'); session_set_cookie_params(0, '/'); session_start(); $globals = array($_REQUEST, $_SESSION, $_SERVER, $_FILES); foreach ($globals as $global) { foreach(array_keys($global) as $key) { unset($$key); } } } the above destroys all globals if register_globals is on, as I understand it. However, if it does destroy all globals, can a web form continue to work? How do you allow form fields and other stuff to be used in a script even if you kill all the globals up front? Many thanks |
