How do you do multiple page titles with on header file? Theres one thing though. For the index page, i've got
error_reporting(0);
if ($_GET["error"]=="404") {
include("forum/styles/art_air/web_template/overall_header.php");
include("include/404");
include("include/index");
include("forum/styles/art_air/web_template/overall_footer.php");
} else {
include("forum/styles/art_air/web_template/overall_header.php");
include("include/index");
include("forum/styles/art_air/web_template/overall_footer.php");
}
So i would have the header before anything else. So how would i manage to make so that
index?error=404 and index have different titles? Thanks in advance.
In overall_header.php
<?php
$title = "Hello, wolrd!";
if ( $_GET["error"] == "404" ) {
$title = "Error";
}
?>
<title><?php echo $title; ?></title>
Use JavaScript and document.title.
Example:
<script language="javascript">document.title = "My Title"</script>
JS can be used in body.
Another method is to set a $GLOBAL variable before including everything.
Example:
error_reporting(0);
$GLOBALS['404'] = 0;
if ($_GET["error"]=="404") {
$GLOBALS['404'] = 1;
include("forum/styles/art_air/web_template/overall_header.php");
include("include/404");
include("include/index");
include("forum/styles/art_air/web_template/overall_footer.php");
} else {
$GLOBALS['404'] = 0;
include("forum/styles/art_air/web_template/overall_header.php");
include("include/index");
include("forum/styles/art_air/web_template/overall_footer.php");
}
In your overall_header.php:
if($GLOBALS['404'] == 1) echo '<title>404: Not Found</title>';
else echo '<title>My Title</title>';
You could try a switch
<?php
$page = $_SERVER['PHP_SELF'];
switch($page) {
case "index.php":
echo "<title>My Homepage</title>";
break;
case "apples.php":
echo "<title>The Best Apples!</title>";
break;
case "bananas.php":
echo "<title>We Sell Bananas</title>";
break;
}
?>

I am trying to exclude a page from including code onto a webpage and can't think of a function that would accomplish this.
'''
include "header.php";
if ($_GET['page'] == ""){
echo "<meta http-equiv='refresh' content='0; URL=/?page=home' />";
}else{
$page = $_GET['page'];
include $page.".php";
}
include "footer.php";
if ($GET['page'] == "handyman.php"){
}
'''
I just want this page to be excluded from showing the footer. Any direction would be greatly appreciated!
You can do safe using Query String, Parse_Str and Switch, below the wished result:
<?php
ini_set('default_charset', 'UTF-8');
$gurl = $_SERVER['QUERY_STRING'];
$ourl = array();
parse_str($gurl, $ourl);
if (isset($ourl['page']) || (!empty($ourl['page']))) {
$page = htmlspecialchars($ourl['page'], ENT_QUOTES, 'UTF-8');
switch ($page) {
case 'register':
include("header.php)";
include("register.php");
include("footer.php");
break;
case 'signup':
include("header.php)";
include("signup.php");
include("footer.php");
break;
case 'login':
include("header.php)";
include("login.php");
include("footer.php");
break;
case 'handyman':
include("header.php)";
include("handyman.php");
#include("footer.php"); // footer not included
break;
default:
include("header.php)";
include("home.php");
include("footer.php");
}
} else {
exit("No available options...");
}
?>
Not tested written on fly... use is simple:
your_page.php?page=handyman
your_page.php?page=register
your_page.php?page=etc...
Do a negativity test on the page you do NOT want the footer on.
if ($_GET['page'] != '"handyman'){
include "footer.php";
}
Your code should look like this.
include "header.php";
if ($_GET['page'] == ""){
echo "<meta http-equiv='refresh' content='0; URL=/?page=home' />";
}else{
$page = $_GET['page'];
include $page.".php";
}
if ($_GET['page'] <> "handyman.php"){
include "footer.php";
}
After my form has been submitted and my message has been sent I want to go back to the index which this does, but I also want to display echo 'Message has been sent' in the index.php in a div instead of my process.php, how would I go about doing this. Sort of new to php if you need any more of my code I will provide or link to site. Thanks.
This is what i tried so far.
in my process.php file
if(!$mail->send()) {
$output = 1;
// $output = 'Mailer Error: ' . $mail->ErrorInfo;
} else {
$output = 2;
header('Location:index.php');
}
in my index.php file
<?php
if ($output == 2) {
echo "<b>Message has been sent</b>";
} elseif ($output == 1) {
echo "<b>Message could not be sent, please try again</b>";
} else {}
?>
The variable $output isn't set in your index.php file.
As an easy way to start you can try it like
header('Location:index.php?output='.$output);
and fetch output in your index.php with
$output = $_GET['output'];
at the beginning of your file, that way you will be able to make your if statements work.
Also be advised that you will never be redirected if $output = 1 in your process.php, as the header is only in the else statement. Simply place the header after your else statements closing bracket.
if(!$mail->send()) {
$output = 1;
} else {
$output = 2;
}
header('Location:index.php?output='.$output);
die();
index.php:
<?php
if (isset($_GET['output'])) {
$output = $_GET['output'];
if ($output == 2) {
echo "<b>Message has been sent</b>";
} elseif ($output == 1) {
echo "<b>Message could not be sent, please try again</b>";
}
}
Please be advised that you shouldn't use unsanitized request data (user input and what so ever) in a production environment, as this is a security risk.
This won't work, the value won't get passed to the index this way:
} else {
$output = 2;
header('Location:index.php');
}
Your options (short of redesigning the way it works) are POST or GET;
} else {
$output = 2;
header('Location:index.php?sent=1');
}
Then in your index.php:
<?php
if (isset($_GET['sent']) && $_GET['sent'] == 1) {
echo "<b>Message has been sent</b>";
}
?>
I'm using the php code:
<body id="<?php echo str_replace("index.php?","",(basename($_SERVER['REQUEST_URI'],".php"))); ?>">
and
<?php
if(isset($_GET['start'])){
include('includes/start.php');
}else if(isset($_GET['help'])){
include('includes/help.php');
}else{
include('includes/start.php');
}
?>
It works great - cutting index.php?help to "help" and index.php?start to "start" in body ID. But when I enter index.php in body ID is "index" not "start". Is there any way to tell index.php with included start.php to display "start" id body ID?
UPDATE
It should work dynamically - body ID is name of included .php file, something like this code:
<?php
$page = str_replace(array( 'server_name', 'index', '?', '/', '.php'), '', $_SERVER['REQUEST_URI']);
$page = $page ? $page : 'start';
?>
<body id="<?php echo $page ?>">
Am not sure i get you 100% but you can try
$id = $_SERVER['QUERY_STRING'];
$bodyID = $id;
switch ($id) {
case "help" :
include ('includes/help.php');
break;
default :
$bodyID = "start";
include ('includes/start.php');
break;
}
printf("<body id=\"%s\" >", $bodyID);
If you run index.php?help it would include include ('includes/help.php'); and also output
<body id="help" >
It would be best to use this instead:
<?php
$ids = 'start,help,something';
$ids = explode(',',$ids);
$included = 0;
foreach ($ids as $id) {
if (isset($_GET[$id])) {
include('includes/'.$id.'.php');
$included = 1;
break;
}
}
if (!$included) include('includes/'.$ids[0].'.php');
?>
Then:
<body id="<?php echo $id; ?>">
How can I write the following statement in PHP:
If body ID = "home" then insert some html, e.g.
<h1>I am home!</h1>
Otherwise, insert this html:
<p>I'm not home.</p>
Doing it with native PHP templating:
<?php if ($bodyID==='home') { ?>
<h1>I am home!</h1>
<?php } else { ?>
<p>I'm not home!</p>
<?php } ?>
You can try using this :
$html = '';
if ( $body_id === 'home' )
{
$html .= '<h1>I am home!</h1>';
}
else
{
$html .= '<p>I\'m not home.</p>';
}
echo $html;
This will echo the html code depending on the $body_id variable and what it contains.
You can use a switch command like so:
switch($body)
{
case 'home': //$body == 'home' ?
echo '<h1>I am home!</h1>';
break;
case 'not_home':
default:
echo '<p>I'm not home.</p>';
break;
}
The default means that if $body does not match any case values, then that will be used, the default is optional.
Another way is as you say, if/else statements, but if within template / view pages you should try and use like so:
<?php if ($body == 'home'):?>
<h1>I am home!</h1>
<?php else:?>
<p>I'm not home!</p>
<?php endif; ?>
Assuming $bodyID is a variable:
<?php
if ($bodyID==='home') {
echo "<h1>I am home!</h1>";}
else {
echo "<p>I'm not home!</p>";}
?>
Personally I think that the best way to do that without refreshing and without having to set a variable (like $body or something like that) is to use a javascript code, this because "communications" between JS & PHP is a one-way communication.
<script language="javascript">
<!--
if( document.body.id === "home" ){
window.document.write("<h1>I am home!</h1>") ;
}
else{
window.document.write("<p>I'm not home!</p>") ;
}
-->
</script>
otherwise you can build a form and then take the body.id value using $_GET function... It always depends on what you've to do after you now body.id value.
Hope this will be usefull & clear.
you can try in the following way:
$body_id = "home";
if ($body_id == "home") {
echo "I am home!";
} else {
echo "I am not home!";
}
or
$body_id = "home";
if (strcmp($body_id, "home") !== 0) {
echo 'I am not home!';
}
else {
echo 'I am home!';
}

How do I get this to pull my 2nd variable? (I already have a switch setup)
<body id="<?php if (! isset($_GET['page'])) { echo "home"; } else { $_GET['page']; echo $page; } ?>">
I have a switch statement that pulls the pages from
index.php?page=#####
and I have just added this part to my switch:
index.php?page=####§ion=#####
Right now, if I am on page=photos, my code ends up being:
<body id="photos">
I need to make it so that if any link has the "sections" variable on it like this page=photos§ion=cars it uses the same ID:
<body id="photos">
First of all, a HTML element can only have one id. So if you want to create a hybrid (e.g. page-section) you can do something like this:
<body id="<?php echo isset($_GET['page']) ? $_GET['page'] : "home"; echo isset($_GET['section']) ? ("-".$_GET['section']) : ''; ?>">
For more information on Ternary Operators in PHP (the ? and : I used in the echo statement) see http://php.net/manual/en/language.operators.comparison.php
I am not entirely sure I understand your question, but where you're doing:
$_GET['page']; echo $page;
What do you think is happening? You're echoing a variable that has no definition. If you want to echo the value passed in the url, just do:
echo $_GET['page'];
GET doesnt mean your getting the varible, its the method by which the variable was passed to he page. The possible methods are get (in the url) or post (not).
Wouldn't that be an if to find out it if the section was defined? i.e.
if(isset($_GET['section'])){
//create div
} elseif(isset($_GET['page']){
//create fallback div
}
Move the PHP code outside the body's id attribute for readability, and use else if. Make sure your code isn't vulnerable to injection by sanitizing or validating input from $_GET. For example:
<?php
function isValidID($x) {
return preg_match('/^[A-Z][-_.A-Za-z0-9]$/i', $x);
}
if (isset($_GET['section']) && isValidID($_GET['section'])) {
$bodyID = $_GET['section'];
} else if (isset($_GET['page']) && isValidID($_GET['page'])) {
$bodyID = $_GET['page'];
} else {
$bodyID = 'home';
}
?>
...
<body id="<?php echo $bodyID; ?>">
Alternatively,
<?php
function isValidID($x) {
return preg_match('/^[A-Z][-_.A-Za-z0-9]$/i', $x);
}
$bodyID='home';
foreach (array('section', 'home') as $key) {
if (isset($_GET[$key]) && isValidID($_GET[$key])) {
$bodyID = $_GET[$key];
break;
}
}
?>
...
<body id="<?php echo $bodyID; ?>">
In this case, I'd use the first, unrolled version. If you had to check more input keys, use the loop-based approach.
If you decide you want both page & section in the ID, you can try something like:
<?php
function isValidID($x) {
return preg_match('/^[A-Z][-_.A-Za-z0-9]$/i', $x);
}
if (isset($_GET['page']) && isValidID($_GET['page'])) {
$bodyID = $_GET['page'];
} else {
$bodyID = 'home';
}
if (isset($_GET['section']) && isValidID($_GET['section'])) {
$bodyID .= '_' . $_GET['section'];
}
?>
...
<body id="<?php echo $bodyID; ?>">
