PHP - Correct Variable Use
Hi,
just joined today.
I am using a variable to chose a template dependent on when the user is logged in it shows a search box or not if they haven't. As a php beginner I just want to know if this is the correct method or should I be declaring 'template' somewhere specific.
It is only used in this one file.
I hope I've used the code tags correctly...
<php?
include_once("login_status.php")
If(user_login==true){
$template="template_top.php"
...web page with search box
}else{
...web page without search box
$template="template_top_NoSearch.php"
}
?>
<html>
<?php include_once($template); ?>
</html>
Similar TutorialsHi. Below is a working PHP script. How do I echo the variable "artist" the correct way? I've tryed everything I know, but cant get this to work ... (in chronoforms in Joomla 1.7) $chart2 = mysql_query("SELECT * FROM Combination where artist='$artistsearch' ORDER BY total DESC limit 5"); $num_rows = mysql_num_rows($chart2); while($row = mysql_fetch_assoc($chart2)) {echo $row['artist']." ... " .$row['city']." (" .$row['country'].") " .$row['total']." USD<br>";} Best regards Morris I am uncertain of how to go about checking if my variables have values, and if I have to do this at every step in my code?! For instance... In my "Member" table, the fields "id" and "name" are required. So when I run this query, presumably there are always values there, right? Code: [Select] // Build query. $q = 'SELECT id, first_name FROM member WHERE email=? AND pass=?'; 1.) Is that a fair assumption? After the above code, I initialize these two variables... Code: [Select] // Initialize variables. $memberID = $memberFirstName = ''; Next I have... Code: [Select] // Bind result-set to variables. mysqli_stmt_bind_result($stmt, $memberID, $memberFirstName); 2.) Did I need to initialize those two variables if I am assigning them values a few lines down? 3.) Can I assume that "$memberID" and "$memberFirstName" will have values based on the comments above? Then a few more lines after this, I have... Code: [Select] // Set Session variables. $_SESSION['memberID'] = $memberID; $_SESSION['memberFirstName'] = $memberFirstName; $_SESSION['loggedIn'] = TRUE; 4.) Again, do I need to keep checking for values (e.g. using ISSET)?? I suppose *anything* is possible, but you could also make your code so full of error-checking code that it would come to a screeching halt?! Please enlighten me!! Debbie It's pretty simple to see what I am trying to do here. For some reason all results in the table are the same exact cityName replacing all existing records. The echoed results are correct. I've include a small dump of my table as well. $query = "SELECT cityName FROM sys_city_dev_2"; $resource = mysqli_query($cxn, $query) or die("MySQL error: " . mysqli_error($cxn) . "<hr>\nQuery: $query"); while($result = mysqli_fetch_assoc($resource)) { $nox = $result['cityName']; $toUpper = ucfirst($nox); echo "$toUpper" . "<br />"; $setString = "UPDATE sys_city_dev_2 SET cityName = '" . $toUpper ."' WHERE cityName != ''"; mysqli_query($cxn,$setString); } 100 Records of table dump (pre running my script above): -- -- Table structure for table `sys_city_dev_2_backup` -- CREATE TABLE IF NOT EXISTS `sys_city_dev_2_backup` ( `ID` int(11) NOT NULL AUTO_INCREMENT, `Mid` int(11) NOT NULL DEFAULT '0', `cityName` varchar(30) NOT NULL DEFAULT '', `forder` int(4) NOT NULL DEFAULT '0', `disdplay` int(4) NOT NULL DEFAULT '0', `cid` int(11) NOT NULL DEFAULT '0', PRIMARY KEY (`ID`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=113970 ; -- -- Dumping data for table `sys_city_dev_2_backup` -- INSERT INTO `sys_city_dev_2_backup` (`ID`, `Mid`, `cityName`, `forder`, `disdplay`, `cid`) VALUES (84010, 1, 'dothan', 0, 0, 0), (84011, 1, 'alabaster', 0, 0, 0), (84012, 1, 'birmingham', 0, 0, 0), (84013, 2, 'flagstaff', 0, 0, 0), (84014, 1, 'auburn', 0, 0, 0), (84015, 1, 'florence', 0, 0, 0), (84016, 1, 'gadsden', 0, 0, 0), (84017, 1, 'huntsville', 0, 0, 0), (84018, 1, 'mobile', 0, 0, 0), (84019, 1, 'montgomery', 0, 0, 0), (84020, 1, 'tuscaloosa', 0, 0, 0), (84021, 2, 'mohave valley', 0, 0, 0), (84022, 2, 'phoenix', 0, 0, 0), (84023, 2, 'prescott', 0, 0, 0), (84024, 2, 'sierra vista', 0, 0, 0), (84025, 2, 'tucson', 0, 0, 0), (84026, 2, 'yuma', 0, 0, 0), (84027, 3, 'bakersfield', 0, 0, 0), (84028, 3, 'chico', 0, 0, 0), (84029, 3, 'fresno / madera', 0, 0, 0), (84030, 3, 'gold country', 0, 0, 0), (84031, 3, 'humboldt county', 0, 0, 0), (84032, 3, 'imperial', 0, 0, 0), (84033, 3, 'inland empire', 0, 0, 0), (84034, 3, 'los angeles', 0, 0, 0), (84035, 3, 'alhambra', 0, 0, 0), (84036, 3, 'merced', 0, 0, 0), (84037, 49, 'fayetteville', 0, 0, 0), (84038, 49, 'fort smith', 0, 0, 0), (84039, 49, 'jonesboro', 0, 0, 0), (84040, 49, 'little rock', 0, 0, 0), (84041, 49, 'arkadelphia', 0, 0, 0), (84042, 49, 'texarkana', 0, 0, 0), (84043, 3, 'modesto', 0, 0, 0), (84044, 3, 'alta sierra', 0, 0, 0), (84045, 3, 'alpine', 0, 0, 0), (84046, 3, 'pedley', 0, 0, 0), (84047, 3, 'redding', 0, 0, 0), (84048, 3, 'alondra park', 0, 0, 0), (84049, 3, 'sacramento', 0, 0, 0), (84050, 4, 'canon city', 0, 0, 0), (84051, 3, 'san luis obispo', 0, 0, 0), (84052, 3, 'santa barbara', 0, 0, 0), (84053, 3, 'stockton', 0, 0, 0), (84054, 3, 'aliso viejo', 0, 0, 0), (84055, 3, 'visalia', 0, 0, 0), (84056, 3, 'yuba city', 0, 0, 0), (84057, 4, 'boulder', 0, 0, 0), (84058, 4, 'colorado springs', 0, 0, 0), (84059, 4, 'denver', 0, 0, 0), (84060, 4, 'applewood', 0, 0, 0), (84061, 4, 'pueblo', 0, 0, 0), (84062, 4, 'air force academy', 0, 0, 0), (84063, 5, 'avon', 0, 0, 0), (84064, 5, 'hartford', 0, 0, 0), (84065, 5, 'new haven', 0, 0, 0), (84066, 5, 'ansonia', 0, 0, 0), (84067, 5, 'fairfield', 0, 0, 0), (84068, 7, 'daytona beach', 0, 0, 0), (84069, 7, 'sebastian', 0, 0, 0), (84070, 5, 'wallingford center', 0, 0, 0), (84071, 8, 'belvedere park', 0, 0, 0), (84072, 7, 'sarasota springs', 0, 0, 0), (84073, 7, 'sandalfoot cove', 0, 0, 0), (84074, 7, 'san carlos park', 0, 0, 0), (84075, 7, 'st. augustine', 0, 0, 0), (84076, 7, 'tallahassee', 0, 0, 0), (84077, 7, 'safety harbor', 0, 0, 0), (84078, 7, 'ruskin', 0, 0, 0), (84079, 8, 'athens-clarke county', 0, 0, 0), (84080, 8, 'atlanta', 0, 0, 0), (84081, 8, 'augusta-richmond county', 0, 0, 0), (84082, 8, 'brunswick', 0, 0, 0), (84083, 8, 'columbus', 0, 0, 0), (84084, 8, 'americus', 0, 0, 0), (84085, 8, 'acworth', 0, 0, 0), (84086, 8, 'valdosta', 0, 0, 0), (84087, 10, 'boise', 0, 0, 0), (84088, 10, 'ammon', 0, 0, 0), (84089, 10, 'moscow', 0, 0, 0), (84090, 10, 'blackfoot', 0, 0, 0), (84091, 10, 'twin falls', 0, 0, 0), (84092, 10, 'meridian', 0, 0, 0), (84093, 10, 'jerome', 0, 0, 0), (84094, 10, 'idaho falls', 0, 0, 0), (84095, 11, 'addison', 0, 0, 0), (84096, 10, 'garden city', 0, 0, 0), (84097, 10, 'eagle', 0, 0, 0), (84098, 10, 'chubbuck', 0, 0, 0), (84099, 10, 'caldwell', 0, 0, 0), (84100, 12, 'bloomington', 0, 0, 0), (84101, 12, 'evansville', 0, 0, 0), (84102, 12, 'fort wayne', 0, 0, 0), (84103, 12, 'indianapolis', 0, 0, 0), (84104, 12, 'muncie / anderson', 0, 0, 0), (84105, 12, 'lafayette / west lafayette', 0, 0, 0), (84106, 12, 'south bend / michiana', 0, 0, 0), (84107, 12, 'terre haute', 0, 0, 0), (84108, 12, 'northwest indiana', 0, 0, 0), (84109, 13, 'ames', 0, 0, 0); I am trying to allow the user to update a variable he chooses by radio buttons, which they will then input text into a box, and submit, to change some attributes.

I am very new to PHP, and I am not sure where to look or what I'm looking for in my current assignment. My task is to take in two numbers between 0-100. Once I take in that number, it should state beside it "The __ was accepted." The program should not accept any numbers greater than 100 or any characters. Once I do this, I must take a second number and do a similar thing. Finally, I must have a statement show up at the bottom stating which number is greater. Essentially, I need help in determining what I should use to place parameters, and how I can keep the program from echo ing any statement until input has been taken and tested for parameters. Any help you can provide will be greatly appreciated! hi i would like to know why this doesnt work .the problem is that it doesnt give me multiple tr-s like td-s.it only works for one tr and multiple td-s. help apreciated

Edited by Maq, 16 May 2014 - 02:18 PM. Hi, Is this the correct way to go by setting cookies for my login 'remember' functionality?, I've posted the relevant login and logout code. Login: <?php session_start(); //some code... if (isset($_POST['remember'])) { $expire = time() + 1728000; // Expire in 20 days $site_domain = 'phpfreaks.com'; //example $_SESSION['username'] = $_POST['username']; //don't worry this has been validated :D $username = $_SESSION['username']; //some sql query to fetch code.. $code = $row['code']; setcookie('username', $username, $expire, NULL, ".$site_domain", NULL, TRUE); setcookie('code', $code, $expire, NULL, ".$site_domain", NULL, TRUE); } ?> Logout: <?php session_start(); if (isset($_COOKIE['username'])) { $expire = time() - 1728000; // Expire in 20 days $site_domain = 'phpfreaks.com'; //example $username = $_SESSION['username']; //some sql query to fetch code.. $code = $row['code']; setcookie('username', $username, $expire, NULL, ".$site_domain", NULL, TRUE); setcookie('code', $code, $expire, NULL, ".$site_domain", NULL, TRUE); } unset($_SESSION['username']); $_SESSION = array(); session_destroy(); ?> Please tell me if it looks good to go and/or any improvements. PS: I want it accessible on all areas of the domain (including subdomains and paths etc.), and HTTP ONLY (so js can't access it) - I believe I've set the right parems? My login script stores the user's login name as $_SESSION[ 'name'] on login. For some unapparent reason, i'm getting errors stating that $user and $priv are undefined variables, though I've attempted to define $user as being equal to $_SESSION['name'], using $user to look up the the user's privilege level (stored as the su column ) in the SQL table, and then where the result of the sql query is $priv which is then evaluated in an if statement. I can't seem to figure out why this might not be working. The code I'm using:
<?php
session_start();
function verify() {
//verify that the user is logged in via the login page. Session_start has already been called.
if (!isset($_SESSION['loggedin'])) {
header('Location: /index.html');
exit;
}
//if user is logged in, we then lookup necessary privleges. $_SESSION['name'] was written with the login name upon login. Privleges // are written in db as a single-digit integer of of 0 for users, 1 for administrators, and 2 for special users.
$user === $_SESSION['name'];
//Connect to Databse
$link = mysqli_connect("127.0.0.1", "database user", "password", "database");
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
exit;
}
//SQL Statement to lookup privlege information.
if ($result = mysqli_query($link, "SELECT su FROM accounts WHERE username = $user", MYSQLI_STORE_RESULT)) {
//LOOP TO CYCLE THROUGH SQL RESULTS AND STORE Privlege information as vairable $priv.
while ($row = $result->fetch_assoc()) {
$priv === $row["su"];
}
}
// close SQL connection.
mysqli_close($link);
// Verify privleges and take action. Only a privlege of "1" is allowed to view this page. A privlege of "2" indicates special
//accounts used in other scripts that have certain indermediate additional functions, but are not trusted administrators.
if ($priv !== 1) {
echo $_SESSION['name'];
echo "you have privlege level of $priv";
echo "<br>";
echo 'Your account does not have the privleges necessary to view this page';
exit;
}
}
verify();
?>

Thanks Hello everyone, I am new to php and I need a confirmation if this is the correct approach for a code I wrote. Basically, I have a contacts.php page where I have a bootstrap table and a modal with some fields to add a new contact. I managed to write all the code, it works perfect but I want to know if this approach is ok. The application will be much more complex and I don;t want to start on the wrong foot here. I have 2 files: contacts.php and add_new_contact.php. First file, contacts.php:
<!DOCTYPE html>
<html lang="en" dir="ltr">
<head>
<!-- ............ -->
</head>
<body>
<!-- ............ here is the page layout-->
<!-- Then I have my modal from bootstrap -->
<div class="modal fade" id="addContact" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<form action = "add_new_contact.php" method="post">
<!-- .....content with all the inputs -->
<button type="submit" class="btn btn-primary">Save to database</button>
</form>
</div>
</body>
</html>
Now, in form action I am telling html to go to add_new_contact.php where I wrote the code for inserting all the values to the database. When doing this, it opens the page and it stays blank because there is no html there. So, in that php file I added a redirect code to the initial contacts.php. Here is the code: Second file: add_new_contact.php:
<?php
//all the code needed to insert the contact in the database
header("Location: http//..../contacts.php");
exit();
?>
So, this works fine. But is this the best way to do it? Thank you. I have a foreach() that I want to run and I want to check before I test it out if this is even possible or how I would do this correctly if it isn't. I have 3 arrays that all pull data from a database earlier in the script. These three all "match" so that they all belong to the same product, but they are from different queries. I want a foreach() to extract data from all 3 of them and insert that into a database until the arrays run out of data. foreach (($titles_list as $title) && ($prices_list as $price) && ($services_list as $service_id)) { mysql_query("INSERT INTO product_invoices (name, invoice_id, price, quantity, date_time, service_id) VALUES('$title', '$invoice_id', '$price', '$today_slashes', '$service_id')") or die(mysql_error()); } Hopefully you see where I'm going with this. What is the correct way to use the backslash here? I am using an ftp script and retrieving the brand directory name through url. I want to catch it if they try to use \ in the url to list all directories. Code: [Select] elseif($_GET[f]=="\") { echo "You have entered an invalid vendor."; $_SESSION['brand_path'] = "INVALID"; } This is what i am trying to achieve for my URL categories=$pagename &id=$myid this is what i am currently doing having some syntax errors please would appreciate if some one can resolve this the code is below echo "<a href=\"./categories.php?name=".$pagename.&id=$myid."\">\".$myid.\".\"</a>\"\n"; Hello all, I'm trying to write a joomla page that will import LinkShare banners into the banner component. The problem I'm having is that LinkShare doesn't seem to always have the correct image size listed. If I use their dimensions, the images come out skewed and bad looking. So I'm trying to use getimagesize, to get the real dimensions, and it's still not working. Please take a look, and let me know if you have any suggestions.

Should functions really be used for tasks such as in my example below? I’m attempting to use some for smaller tasks to improve readability and reduce code repetition. Or should they be used for larger tasks?
functions.php
function accessDenied(){
$_SESSION[‘error’] = "You cannot view that page, you wally";
header(‘location: error.php’);
exit;
}
page.php
if(!$loggedin){ accessDenied(); }
