header.php
<?php
$conn = mysql_connect('localhost', '-', '-');
#mysql_select_db('accmaker', $conn) or die("Unable to select database");
?>
<html>
<head>
<title>Mysite.com - <?php isset($pageTitle) ? $pageTitle : 'Home'; ?></title>
</head>
<body>
profile.php
require 'header.php';
$q = mysql_query("SELECT * FROM users WHERE username = '$username'");
$r = mysql_fetch_assoc($q);
$pageTitle = "Profile of $r[username]";
I think you understand what i want
I cant include header.php after the query, because i wont be connected to mysql
waht do you suggest other than having the connection snippet on every page
What do I suggest? A MVC (Model-View-Controller) Framework like Kohana. If you don't want to go that route, break your connection off into its own file:
<?php
# connect
require_once("connection.php");
# load page data array
require_once("page-data.php");
?>
...
<title><?php print $page["title"]; ?></title>
Note here how I have a $page array of data. This will be helpful when debugging later rather than having several independent variables. With an array of page data, I can quickly see all of the information laid out for any given page:
print "<pre>";
print_r($page);
print "</pre>";
Determining your title should be done within page-data.php, rather than on your page:
$config["site_name"] = "Bob's Shoe Mart";
$config["admin_email"] = "bob#shoemart.com";
/* query to get $row['title'] */
$page["title"] = (!empty($row["title"])) ? $row["title"] : $config["site_name"] ;
Not sure of a "best" solution, but we currently include multiple files. We have our "utilities.php" file that connects to the database and provides some nice functions. We then set our page titles and then we include "top.php" which is the layout portion. It doesn't have anything except HTML with a little bit of PHP for display purposes. Looks like this:
include "utilities.php";
$pageTitle = "Welcome";
include "top.php";

Hello im using two files 1. layout.html.php(for all the HTML code) 2.layout.php(for all the PHP code)
Im trying to send a variable from the layout.php to layout.html.php file
The variable is equal to a list of all jobs from a database table
See code below
I want to use this list of jobs in a unordered list as links in layout.html.php file
I would appreciate any help i can get with this
CODE FOR LAYOUT.HTML.PHP
<li>Jobs
<ul>
<?php
foreach ($jobs as $job){?>
<li><?= $job['name']?> </li>
<?php }?>
</ul>
CODE FOR LAYOUT.PHP
<?php
require '../loadTemplate.php';
$stmt = $pdo->prepare('SELECT * FROM job');
$stmt->execute();
$jobs= $stmt->fetchAll();
$templateVars = ['stmt' => $jobs];
$output = loadTemplate('../templates/layout.html.php',['stmt' => $jobs]);
require '../templates/layout.html.php';
?>
If in a file A you got the variable X:
<?php
$frase = "abcdef";
?>
Then if you want to use the same variable in another file you can use:
<?php
include('A.php');
echo $frase;
?>
There is other ways to do that. You can also use the Session, cookies, or just pass in the url.
In my case, I like to do in that way:
I have a page home.php. In that page I represents a consult. So, in home.php I got:
<?php
include 'php/db.php'
$result = BuscaDados();
while($row = $result->fetch_assoc()){
// here you get all lines
}
?>
In db.php I got a implementation of my functions that return the consult. Try it out.
I'm trying to echo out dynamic php titles depends on page for seo purposes.
I successfully did this the pages I call from database depends on their id's.
Like that:
if (isset($_GET["category_id"])) {
$query = $handler->query("SELECT * FROM categories WHERE category_id = ".$_GET['category_id']." ");
while($r = $query->fetch()) {
$title = $r["title"];
}
}
And this is how I echo out:
<title><?php if (isset($_GET["category_id"])) { echo $title; echo " |"; } ?> mypage.com</title>
result:
on category.php?category_id=1 Page title is: "Category 1 | mypage.com"
*
But there are pages which is not static.
for example: index.php, login.php.
*
I want to figure out how to edit my code below to print "Login" on login.php between title tags.
<title>
<?php
if (isset($_GET["category_id"])) {
echo $title; echo " |";
}
?> mypage.com
</title>
EDIT
my login.php is like that:
include("header.php");
content.
So I need to define $title for login.php in header.php
I need to add some codes to header.php when user will see different title on login.php, index.php etc.
I'm able to do it category.php?category?id=1 already with the code above, but I need to also make it for login.php, index.php and so on.
There are several ways to do this within the code you outlined.
First, I'm going to simplify some of your code a bit. This also potentially makes it slightly faster:
echo "<title>$title | mypage.com</title>";
This assumes that $title is going to be set, either by the query from when $_GET['category_id'] is set, or from the file that calls it. The great thing about includes is that they can pass variables. So in the login.php and any other file where you are not doing a GET, just specify $title in that file.
Login.php:
$title = 'Login';
include("header.php");
content.
Which would display page title of "Login | mypage.com".
I am trying to post pictures in a joomla page. I am completely new in php and joomla.
This is what I have in a joomla page:
<h1>Welcome to my home page!</h1>
<p>Some text.</p>
<p>Some more text.</p>
<p><img src="images/test.php?id=8" alt="powered by" />
</p>
<p>Done!</p>
this is test.php:
<?php
$link=...... //connection to database
if(isset($_GET['id']))
{
$id = mysql_real_escape_string($_GET['id']);
$query=...
$result=mysqli_query($link,$query);
while($row=mysqli_fetch_array($result)) {
$imageData = $row['photo'];
}
header("content-type: image/png");
echo $imageData;
}
?>
This is just for a simple 1 photo print, I eventually want to print multiple photos, and have like a slideshow.
Is this possible using joomla?
I also tried several other ways, but I had no luck. Is it possible to have ?
I just need a way through loop through images that are in a database, and print them out. Is there a good approach to this than what I am taking? Do I have to install plugins?
This is a completely wrong approach.
You have to develop a custom module to handle your slideshow task. You could start here.
As for your current code you have to convert it to:
<?php
$db = JFactory::getDbo();
$query = $db->getQuery(true)
->select($db->quoteName('id'))
->from($db->quoteName('#__helloworld'))
->where('id = '. $db->Quote($params));
$db->setQuery($query);
$results = $db->loadObjectList();
print_r($results);
?>
Please check the full list of joomla database functions.
This part will help you how you could display your results.
Good Luck!
I'm trying to avoid to query my database twice: for set <title> attribute and also for echo the page title. I want to query it just one time:
Example:
<html>
<head>
<?php
// how should I use here ob_start() ? Is there any other possible way to achieve this?
$title = "";
echo '<title>', $title, '</title>'; // this should be in the end <title>value of $row['page_title']</title>
?>
</head>
<body>
<?php
$sql = $mysqli->query("MY QUERY");
$row = $sql->fetch_assoc();
$title = $row['page_title']; // I want that this assignment to set the variable in the top
// I know that for this job I can use ob_start() but I didn't used it until now
// and I will really appreciate any help from you.
?>
<h1><?php echo $title; ?></h1>
</body>
</html>
I know that I can do the query before echo the title attribute but I don't want to do it like that. Do you have any suggestion? or can you show me how to use that ob_start() / ob_clean() functions?
Thank you!
Shift the query to the top of the code and reuse the variables!
<?php
$sql = $mysqli->query("MY QUERY");
$row = $sql->fetch_assoc();
$title = $row['page_title'];
?>
<html>
<head>
<?php echo '<title>', $title, '</title>'; ?>
</head>
<body>
<h1><?php echo $title; ?></h1>
</body>
</html>
ob_start();, in usual sense, won't help you have. However, you can use ugly solution like this:
ob_start();
echo '
<html>
<head>
<title>{title}</title>
</head>
<body>
';
$header = ob_get_clean();
// and then, when you know your title
echo str_replace('{title}', $known_title, $header);
But I strongly recommend taking another approach. You need to choose and fill the template after all data has been gathered and you know all details about which template you want. If you start echoing different parts preemptively, you will get more and more troubles. Now you need to change title for some pages. Then you will need to add css file for specific page and you will have to do that ugly business again. Why not do it the right way?
I have seen the following thread but it's a bit beyond me...
How can I change the <title> tag dynamically in php based on the URL values
Basically, I have a page index.php (no php in it just named to future proof - maybe now!). It contains numerous lightbox style galleries which can be triggered from an external link by a variable in the URL - e.g. index.php?open=true2, index.php?open=true3, etc.
I would like the index.php title tag - to include existing static data + append additional words based on the URL variable - e.g. if URL open=true2 add "car gallery", if URL open=true3 add "cat gallery", if URL has no variable append nothing to title.
Can anyone assist? I have been searching but either missed the point of posts or it hasn't been covered (to my amateaur level).
Many thanks. Paul.
At the top of your php script put this:
<?php
# define your titles
$titles = array('true2' => 'Car Gallery', 'true3' => 'Cat Gallery');
# if the 'open' var is set then get the appropriate title from the $titles array
# otherwise set to empty string.
$title = (isset($_GET['open']) ? ' - '.$titles[$_GET['open']] : '');
?>
And then use this to include your custom title:
<title>Pauls Great Site<?php echo htmlentities($title); ?></title>
<title>Your Static Stuff <?php echo $your_dyamic_stuff;?></title>
<?php
if( array_key_exists('open', $_GET) ){
$title = $_GET['open'];
}else{
$title = '';
}
?>
<html>
<head>
<title><?php echo $title; ?></title>
</head>
<body>
The content of the document......
</body>
</html>
http://www.w3schools.com/TAGS/tag_title.asp
http://php.net/manual/en/reserved.variables.get.php
PHP can fetch information from the URL querystring (www.yoursite.com?page=1&cat=dog etc). You need to fetch that information, make sure it's not malicious, and then you could insert it into the title. Here's a simple example - for your application, make sure you sanitise the data and check it isn't malicious:
<?php
$open = "";
// check querystring exists
if (isset($_GET['open'])) {
// if it does, assign it to variable
$open = $_GET['open'];
}
?>
<html><head><title>This is the title: <?php $open ?></title></head>
PHP has lots of functions for escaping data that might contain nasty stuff - if you look up htmlspecialchars and htmlentities you should find information that will help.
Some of the other answers are open to abuse try this instead:
<?php
if(array_key_exists('open', $_GET)){
$title = $_GET['open'];
} else {
$title = '';
}
$title = strip_tags($title);
?>
<html>
<head>
<title><?php echo htmlentities($title); ?></title>
</head>
<body>
<p>The content of the document......</p>
</body>
</html>
Otherwise as #Ben has mentioned. Define you titles in your PHP first to prevent people from being able to directly inject text into your HTML.
