PHP - Passing Variable Between Two Functions
i have two functions. In function two it has $id=9. how do i get function one to echo $id?
how do i adjust the below example to accomplish this? Code: [Select] $newdb = new Database(); class Database { function one() { $newdb->two(); echo $id; } function two() { $id = 9 return $id; } } Similar TutorialsI'm making a registration form and I'm really new at it. I've had a look about at similar issues but feel like I've got my code set up right, I obviously don't. I have a registration_handler.php and a functions.php file. I'm simply trying to pass an array ($errors[]) from the functions that generate them to a function that prints them out on registration_handler.php. It seems so easy, but I'm not getting it. Here's my code: from functions.php: (this is just an example of one of the functions)
// USERNAME (MANDATORY)
//uses the clean_names() and checks for empty input
function assign_username() {
global $conn;
$username = $_POST['username'];
if(!$username){
$errors[] = "A username is mandatory";
echo "A username is mandatory <br>";
} else {
$username = clean_names($username);
}
//check for duplicate username and return $username if doesn't exist already
$username_check = mysqli_query($conn, "SELECT username FROM users WHERE username='$username'");
$number_rows = mysqli_num_rows($username_check);
if($number_rows > 0) {
$errors[] = "Username already in use <br>";
echo "Username already in use <br>";
} else {
return $username;
}
return $errors;
} // END USERNAME
Also from functions.php, the function to print out the error array:
//display error array
function show_errors($errors) {
print_r($errors);
}
and the function call from registration_handler.php:
if(isset($_POST['register_button'])) {
//assign clean form variables
$firstname = assign_firstname();
$lastname = assign_lastname();
$username = assign_username();
$email = assign_email();
$password = assign_password();
$date = date("Y-m-d");
$errors = array();
show_errors($errors);
}
I'm intentionally leaving the username out to test this on the form but I only get returned Array() It echos "Username is mandatory" but it seems like it's not passing the error string to the error array Can anyone point me towards what I'm doing wrong, please. I appreciate the replies Edited June 11 by TechnoDiverI have a little problem. I have made a script(function) to connect to the database. this is the script: connect(php) Code: [Select] <?php $server = "localhost"; $username = "username"; $password = "password"; function connectdatabase($type,$database) { if($type == "mysql") { $mysql = mysql_connect($server, $username, $password); mysql_select_db($database, $mysql); } else if($type == "mysqli") { $mysqli = new mysqli($server, $username, $password, $database); } else if($type == "mssql") { $mssql = mssql_connect($server, $username, $password); mssql_select_db($database, $mssql); } function query($query) { if($type == "mysql") { mysql_query($query); } else if($type == "mysqli") { $mysqli->query($query); } else if($type == "mssql") { mssql_query($query); } } } ?> and aanmelden(php) Code: [Select] <?php include("config.php"); connectdatabase("mysql", "[ledensysteem]"); //example if(!empty($_POST)) { if(!preg_match('/^[A-Za-z1-9-]{'.$Minimale_Gebruikersnaam_Karakters.',}$/', $_POST['gebruikersnaam'])) { if(!isset($error)){ $error=1;}else{$error=$error+1;} echo "Je gebruikersnaam moet minimaal {$Minimale_Gebruikersnaam_Karakters} tekens bevaten en mag geen komma of andere onbedoelde tekens zijn<br>Toegestaan is <br>A t/m Z <br>a t/m z <br>1 t/m 9 <br>en -"; } else { echo "geldige gebruikersnaam(goedgekeurd)"; } if(preg_match('/^[A-Za-z1-9-]{'.$Minimale_Wachtwoord_Karakters.',}$/', $_POST['wachtwoord']) && preg_match('/^[A-Za-z1-9-]{'.$Minimale_Wachtwoord_Karakters.',}$/', $_POST['herhaalwachtwoord'])) { if($_POST['wachtwoord'] != $_POST['herhaalwachtwoord']) { if(!isset($error)){ $error=1;}else{$error=$error+1;} echo "niet hetzelfde wachtwoord"; } /*else { echo "hetzelfde wachtwoord (goedgekeurd)"; }*/ } else { if(!isset($error)){ $error=1;}else{$error=$error+1;} echo "wachtwoord moet minimaal {$Minimale_Wachtwoord_Karakters} tekens bevatten!"; } if(!preg_match("/^[A-Za-z1-9_.-]{1,}@[A-Za-z1-9-]{1,}\.[A-Za-z1-9]{2,3}$/", $_POST['email'])) { if(!isset($error)){ $error=1;}else{$error=$error+1;} echo "onjuiste email"; } else { echo "goedgekeurd!"; } if(!isset($error)) // this problem is fixed yesterday on phpfreaks.com forum! { echo "goedgedaan geen errors!"; query("SELECT username FROM phpfreaks WHERE password = private"); // example } } else { ?> <HTML> <HEAD> <TITLE>New Document</TITLE> </HEAD> <BODY> <form method="post"> <input type="text" name="gebruikersnaam" value="gebruikersnaam" maxlength="20" size="20"> <input type="password" name="wachtwoord" value="wachtwoord" maxlength="20" size="20"> <input type="password" name="herhaalwachtwoord" value="herhaalwachtwoord" maxlength="20" size="20"> <input type="text" name="email" value="voorbeeld@domeinnaam.extensie" maxlength="50" size="20"> <input type="submit" name="login" value="inloggen"> </form> </BODY> </HTML> <?php } ?> the problem is, is that i want to pass a variable between functions like $type (the database type) between connectdatabase(); and query(); in the 'aanmelden.php' file is an example of how i use the function (on line 3 and 45 the ones with //example comment) thanks for reading. please help. ps. config.php contains include("connect.php"); hi guys im back for more php questions hope you dont get annoyed <?php function getvalue($num) { echo "<input type='text' name='txt1' value='$num'>"; } ?> <html> <head> <title>Home</title> </head> <body> <form action="" method="POST"> <input type="text" name="txt1" id="txt1" value="0"> <input type="button" name="btn1" id="btn1" value="1" onclick="getvalue(1);"> <input type="button" name="btn2" id="btn2" value="2" onclick="getvalue(2);"> </form> </body> </html> here is my code my question is how can i pass the values at the php function? how can i display the passed value to the textbox txt1? is this code correct? echo "<input type='text' name='txt1' value='$num'>"; I everyone, I'm developing a small MVC framework for my personal work, now, in order to have access from all the classes to certain variables I've created a registry class, for this to work I have 2 options: 1.- passing every time the registry object to the constructor class(controllers, models, etc) or 2.- create in the registry static set and get so I can reach the variables by Registry::set(name, value) and Registry::get(name) My question is, which one of this two options takes less resources(is faster)?

This is my form with the select: Code: [Select] <form id="form1" name="form1" method="post" action="products_2.php?id_subcategoria= WHAT SOULD I PUT HERE?"> <select name="subcats" class="subcatsSelectMenu" id="subcats" onchange="this.form.submit()"> <option value="">Ver placas por tipos</option> <?php do { ?> <option value="<?php echo $row_subcats_RS['id_subcategoria']?>"><?php echo $row_subcats_RS['subcategoria_esp']?></option> <?php } while ($row_subcats_RS = mysql_fetch_assoc($subcats_RS));$rows = mysql_num_rows($subcats_RS); if($rows > 0) { mysql_data_seek($subcats_RS, 0); $row_subcats_RS = mysql_fetch_assoc($subcats_RS); } ?> </select> </form>How can I pass the variable in the URL? Thanks I had an iframe working for the last few months on a site at hostgator. Yesterday, it quit working (403 permissions error). After a long bout of trouble-shooting, I found out that it has something to do with mod_security that they have suddenly enabled (have no idea as I'm not a Linux guy). They told me they fixed the problem on my domain by whitelisting it as an exception, but strangely, even though the permissions error went away, the actual src= box of the iframe, which was the url variable I was passing in the url, no longer loads. So.. I'm trying to break this down into the simplest form to figure it out. I just understand php basics so needing some verification that I'm doing this right/wrong. Here's my code.. page1.php Code: [Select] <? $testurl = "http://google.com"; ?> <a href="http://mysite.blah/page2.php?url=<? echo $testurl; ?>">page2.php</a> page2.php Code: [Select] if (isset($_GET['testurl'])) echo $testurl; else echo "sorry dude"; I am only able to print "sorry dude". Am I doing something wrong or shouldn't this send the url? Thanks for the help! hello all, I'm new here and I'm learning mysql/php. Currently I have a dynamic table on one of my webpages, and the loop code looks like this:while ($i < $numRows) { $fname = mysql_result($result, $i, "fname"); $fcode = mysql_result($result, $i, "fcode"); $ftype = mysql_result($result, $i, "ftype"); $fdesc = mysql_result($result, $i, "fdesc"); ?> <tr> <td><a href="showfunction.php?fname=<?php echo "$fname"; ?>" target="_self"> <?php echo "$fname"; ?></a></td> <td> <?php echo "$fdesc"; ?> </td> <td><div align="center"> <?php echo "$ftype"; ?> </div></td> </tr> <?php $i++; } ?> what I would like to do is pass the ''fname'' variable to the "showfunction" page so it can printed from the database. Here is the relevant portion of the page:<body><div class="codeblock"> <div class="title">Code:<br /> </div><code><pre> <?php echo $fcode; ?> </pre></code></div> <br /><pre><hr /> </pre> I know that doesn't work, and I didn't expect it to because there is no way to 'get' the 'fname' variable from the preceeding script. I do not want to use the GET method with this because from what I understand, you can only use it with Forms. I really don't want to put controls in all of my table fields just to be able to pass the function name to the next page. Does that make sense? If I could get a jumpstart on this one last hurdle, I would appreciate it. thank you so much! Cheers. How, if possible, can a $var be passed to the forms action php file? I tried everything with no success. Edited December 24, 2019 by cyberRobotRemoved email address Hi, can anybody please tell me how i can make "Arson" into a php variable Code: [Select] <script type="text/javascript" src="js/swfobject.js"></script> <script type="text/javascript"> swfobject.embedSWF( "open-flash-chart.swf", "my_chart", "550", "400", "9.0.0", "expressInstall.swf", {"data-file":"ofc-chart.php?crime=Arson"} ); </script> This is driving me MAD! The Variable gets passed through the URL but when I try and echo the result I gte NOTHING. First Page. Code: [Select] <?php include'config.php'; $result = mysql_query("SELECT * FROM carbontrust"); while($entry = mysql_fetch_array($result)) Print "$entry[contact] - $entry[company] :: <a href='edit.php?id=$entry[id]'>Edit</a><br>"; exit; ?> Second Page. (Where I want the Variable passed to) Code: [Select] <?php include'config.php'; $id = $_GET['id']; echo "ID: $id"; } ?> Its probably just a stupid error but iv looked through a load of tutorials and this should be correct. :/ The below script for some reason isn't passing along the product_id variable.

I just want some nice person to give me the answer. I'm trying to pass a variable using href to another page. It works great if the variable is only one word. But it only passes the first word. There are multiple posts on this topic, but I can't seem to get any of those fixes to work for me. Here the code. Code: [Select] <?php $query = "select DISTINCT city from daily where open_bid>0 order by city ASC"; $result = mysql_query($query); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $details=''; $details.='<li class="menu"><span class="name"><a href=list.php?city='.$row['city'].'>'.$row['city'].'</a>'; $details.='</li>'; echo($details); } ?> As you can imagine, some cities names are made up of two words. This is only passing the first word. Thanks for your help. I'm starting to fear that this is impossible.. I will severely appreciate any kind of advice! On site A, I have a link (an affiliate type link) that redirects to site B. When clicking the link on site A, I use this code to redirect.. header('HTTP/1.1 301 Moved Permanently'); header('Location: ' . $url); exit; the $url var is just site's A URL. What I can't figure out is how to pass a variable from the redirection script onto site B without using a query string in the URL itself ( for example, http://www.siteB.com/?var_to_pass=something) Can passing a variable between two sites be achieved with js.. or XML? I'm willing to use anything as long as I don;t have to add the variable in the URL. www.mywebpage.co.uk/page22 Is it possible to produce a variable with the value = page22 using only the url above, I know that usually you would use get and post, but I was just curious to know if this had been done before. Okay, I have been looking into this for the last 3 hours, and cant find shit. I have a page with a javascript game where the player moves around on a map. They have an X and Y coordinate, but I'm having a problem. The problem is I need to store that info in a database, and I'm having trouble learning AJAX. Heres a little list of things: Play loads the game. A php variable is taken from a database. The player goes to those X and Y coordinates. The player may move around. Once they move, the player is sent to a php page that updates the Database information. The page is refreshed to the game again, where they may then move around some more. The problem is, when the page is changed the values are lost. For some reasons cookies aren't working at all (like just not working for anything, even a completely different file.) I heard something about using $_GET or $_POST, but I dont see how... I have a menu that i want to be added to every page of my coding using a hidden variable, but i cannot get it to work. I using this with a few if conditions. the index page should navigate every page. can anyone help? I have attached the files to illustrate the coding i have done so far. [attachment deleted by admin] Hello I'm trying to pass a php variable from produto.php to another file descProduto.php it ajax but without success. Please someone can tell me what I'm doing wrong?
