I would just like to hear if it is possible to echo something on one page, and not every other page, even though they all get content from another file.
I have 3 pages, and they all have this in code:
<?php
$path = $_SERVER['DOCUMENT_ROOT'];
$path .= "/index.php";
include_once($path);
?>
If I want "index.php" to echo something that "about.php" does not echo, can you then do it?
As the title says, I'd guess on something like this:
if filename == index.php then
echo=hello
I wouldn't make it so specific If you add more and more pages what will you do? Handle them as special cases one by one? Now you have to handle two pages, after three months they'll be 10...and so on.
It's not a perfect solution but as starting point you may use a flag. Beginning like this:
<?php
$path = $_SERVER['DOCUMENT_ROOT'];
$path .= "/index.php";
$helloWorld = TRUE;
include_once($path);
?>
And in your index.php include file:
if (helloWorld === TRUE) // or if (!!helloWorld)
echo "Hello world";
if (strpos($_SERVER['SCRIPT_NAME'],'index.php') !== false) {
echo "do stuff";
}

I working on a flat-file-based project and I try to remove specific pattern from URL. The content is stored in a "content"-directory with markdown-files. I want sortable content-folder-names like:
contentfolder:
- 01-home
- 01-subpage
- 02-subpage2
- 02-page02
- 01-subpage
- 02-subpage2
etc...
At the moment, the URL would look something like this:
http://domain.com/01-home/02-subpage
This is really ugly ;)
I would prefer to get the url work as follows:
http://domain.com/home/subpage
I would prefer a solution, which works for every case of url:
http://domain.com/home/subpage/subsubpage/subsubsubpage
etc.
My script use at the moment the f3-Wildcard-Solution (GET /*). The requested URL will be replaced to get the content.
function find($path = "") {
$dirname = str_replace(globals::root(), "", globals::current());
if ($dirname == "/") {
$this->location = globals::content() . globals::home() . "/" . $path;
} else {
$this->location = globals::content() . $dirname . "/" . $path;
}
return $this;
}
Thank you guys!
Here's a solution, assuming that:
your markdown files are located in a content/ folder
every subfolder is prefixed with two digits and a hyphen (XX-something)
=>
$f3=require('lib/base.php');
$f3->set('CONTENT','content/');//location of markdown files
$f3->route('GET /*',function($f3,$params){
$path=str_replace('..','',$params[1]);//security
$dirs=glob($f3->get('CONTENT').'??-'.str_replace('/','/??-',$path));
if ($dirs) {
$dir=$dirs[0];//pick first match
echo \Markdown::instance()->convert($dir.'/default.md');
} else
$f3->error(404);
});
$f3->run();
i have a large number of files with several id's in each file. For example file1.php contains a number of paragraphs, each paragraph has a unique id. (id="1",id="2",id="3" etc...) I would like the ability to create a link to a page (page A.php) and pass the location of one of these id's in the url of the link to display in a php include on page A.php The result that i'm looking for is to have the entire file (file1.php) show up inside of page A.php with the specific id that is passed in the url being highlighted. Is this possible? or do I need to use Java Script and an iframe?
Here is what I ended up with:
The url: http://mydomain/thispage.php?xul=http://mydomain.com/folder1/folder2/file.php&id=Abc150:176
The code:
Stylesheet .vrsehilite{styling}
<script type="text/javascript">var x = <?php echo json_encode($_GET["id"]); ?>;</script>
<?php
$invdmn = "<h2>Error: Invalid Domain</h2>";
$filnf = "<h2>Error: File Not Found</h2>";
$pthinv = "<h2>Error: The Path is invalid</h2>";
$idinv = "<h2>Error: The ID is invalid</h2>";
$oops = "<br/><h2>Oops! Something went wrong.<br/><br/>Please click the back button or use the menu to go to a new page.</h2>";
$testdomain = substr_compare ($_GET['xul'],"http://mydomain.com",0,20,FALSE); //make sure the domain name is correct
if ($testdomain == 0) {
$flurl = $_GET['xul'];
} else {
echo $invdmn . " " . $oops;
}
$flurl_headers = #get_headers ($flurl);
if ($flurl_headers[0] == 'HTTP/1.1 404 Not Found') {
echo $filnf . " " . $oops; //Make sure the file exist
} else {
$surl = str_replace (".com/",".com/s/",$flurl);
} //add some characters to url at point to explode
list($url1, $path) = explode ("/s/",$surl); //explode into array of 2 [0]url to domain [1] path
$testpath = substr_compare ($path,"file1/file2/",0,10,FALSE); //make sure the path is correct
if ($testpath == "0") {
$aid = preg_match ("/^[A-Z][a-z]{2}(?:[1-9][0-9]?|1[0-4][0-9]|150):(?:[1-9][0-9]?|1[0-6][0-9]|17[0-6])$/", $_GET['id']);
} else { //make sure the id is valid
echo $pthinv . " " . $oops;
}
if ($aid == 1) {
include($path);
echo "<script type='text/javascript'>";
echo "document.getElementById(x).className = 'vrsehilite';";
echo "document.getElementById(x).scrollIntoView();";
echo "window.scrollBy(0,-100);";
echo "</script>";
} else {
echo $idinv . " " . $oops;
}
?>
Never ever include arbitrary files submitted by the user. Instead, you should only include files from a pre-defined set of your choice. Perhaps something like this:
PHP
$files = array ('file1.php', 'file2.php', 'view.php', 'edit.php');
$id = (int)$_GET['id'];
if (isset ($files[$id])) {
include $files[$id];
} else {
/* Error */
}
Or you could use a regular expression to accept only certain filenames, in this case 1 or more lower case letters followed by 0 or more digits.
$m = array ();
if ( preg_match ('#^http://domain.example/folder1/folder2/([a-z]+[0-9]*\\.php)$#', $m)
&& file_exists ($m[1])) {
include $m[1];
} else {
/* Page not found */
}
You may want to check the return value of include. You may also want to move the folders into the subpattern (...) or use regular expressions for the folder names.
If all you need is to highlight a certain paragraph in a page, you should add a URL fragment that poins to the paragraph's id, and add CSS to style it. Eg:
URL
http://domain.example?id=1#p1
HTML
<p id=p1>This is the target paragraph.
CSS
p:target { /* Style the targeted <p> element */ }
Ok so I am making a website on each page where I want to include a file sidebar.php .
In sidebar.php I would like to echo the name of file that included sidebar.php .
Below are contents of sidebar.php, they return 'sidebar'.
<?php
$file = basename(__FILE__, '.php');
echo $file;
;?>
I found a similar question but the whole point is that I don't have to make no variables in on each page.
Excuse me for vague use of word 'include', I am using the it as the statement in php.
You could pass it to the sidebar page through a session variable:
<?php
session_start();
$_SESSION['filename'] = "thisFilesName.php";
include('../sidebar.php');
?>
sidebar.php:
<?php
session_start();
echo $_SESSION['filename'];
?>
My url contains many variables that I want untouched (don't worry they aren't important).
Let's say it contained...
../index.php?id=5
How would I make a url that just adds
¤t=1
rather than replacing it entirely?
I'd like...
../index.php?id=5¤t=1
rather than..
../index.php?current=1
I know it's a simple question but that's why I can't figure it out.
Thanks.
To append a parameter to a URL you can do this:
function addParam( $url, $param ){
if( strrpos( $url, '?' ) === false){
$url .= '?' . $param;
} else {
$url .= '&' . $param;
}
return $url;
}
$url = "../index.php?id=5";
$url = addParam( $url, "current=1");
You should just create your link to 'add' that parameter
The Link
and then obviously in the index.php somewhere you'll look for the current variable and do what you need to:
<?php
if(isset($_GET['current']) && !empty($_GET['current]) {
// Do stuff here for the 'current' variable
$current = trim($_GET['current']);
}
?>
On the links that you require the $current variable, I suppose that you could just casually put it in the href attribute. For the index,php file, so something like this....
if(isset($_GET['current']))
{
$current = $_GET['current'];
//Do the rest of what you need to do with this variable
}
Try this one:
$givenVar = "";
foreach($_GET as $key=>$val){
$givenVar .= "&".$key."=".$val;
}
$var = "&num=1";
$link = "?".$givenVar."".$var;
echo $link;
You can just add the variable to the href,
When you clink it while the address is
../index.php?id=5
trust me you then go to
../index.php?id=5¤t=1
BUT if you click that link again, than you 'll go to
../index.php?id=5¤t=1¤t=1
Actually I thinks that's tricky and bad practice to just append the variable.
I suggest you to do it like:
<?php
$query = isset($_GET) ? http_build_query($_GET) . '¤t=1' : 'current=1';
?>
A Label
take a look http://us.php.net/manual/en/function.http-build-query.php
I don't know why in Earth you would need this, but here we are. This should do the trick.
$appendString = "¤t=1";
$pageURL = $_SERVER["REQUEST_URI"].$appendString;
$_SERVER["REQUEST_URI"] should return just the name of the requested page, with any other GET variable attached. The other string should be clear enough!
I read several similar posts but I don't see my fault.
index.php looks like:
<head>
<title>Demo Title</title>
</head>
<body>
<?php
require_once "footer.php";
?>
</body>
footer.php looks like:
<?php
/*
* _$ Rev. : 08 Sep 2010 14:52:26 $_
* footer.php
*/
$host = $_SERVER['SERVER_NAME'];
$param = $_SERVER ['REQUEST_URI'];
$url = "http://".$host.$param;
echo $url;
$file = # fopen($_SERVER[$url],"r") or die ("Can't open HTTP_REFERER.");
$text = fread($file,16384);
if (preg_match('/<title>(.*?)<\/title>/is',$text,$found)) {
$title = $found[1];
} else {
$title = " -- no title found -- ";
}
?>
A request for the URL http://127.0.0.1/test/index.php results in:
http://127.0.0.1/test/index.phpCan't open HTTP_REFERER.
or for http://127.0.0.1/test/
http://127.0.0.1/test/Can't open HTTP_REFERER.
Any hints appreciated.
$_SERVER is an array which contains a bunch of fields relating to the server config. It does not contain an element named "http://".$host.$param, so trying to open that as a filename will result in the fopen call failing, and thus going to the die() statement.
More likely what you wanted to do was just open the file called "http://".$host.$param. If that's what you want, then just drop the $_SERVER[] bit and it should work better.
Note that because it's a URL, you will need your PHP config to allow opening of remote files using fopen(). PHP isn't always configured this way by default as it can be a security risk. Your dev machine may also be configured differently to the system you will eventually deploy to. If you find you can't open a remote URL using fopen(), there are alternatives such as using CURL, but they're not quite as straightforward as a simple fopen() call.
Also, if you're reading the whole file, you may want to consider file_get_contents() rather than fopen() and fread(), as it replaces the whole thing into a single function call.
try this:
$file = # fopen($url,"r") or die ("Can't open HTTP_REFERER.");
Try
<?php
$dom = new DOMDocument();
$host = $_SERVER['SERVER_NAME'];
$param = $_SERVER ['REQUEST_URI'];
$url = "http://".$host.$param;
echo 'getting title for page: "' . $url . '"';
$dom->loadHTML($url);
$dom->getElementsByTagName('title');
if ($dom->length)
{
$title = $dom->item(0);
echo $title;
}
else
{
echo 'title tag not found';
}
?>
I can see your trying to track the referral's title
You need to use $_SERVER['HTTP_REFERER']; to get that
what you want to do is something like this
$referrer = (!empty($_SERVER['HTTP_REFERER']) && !substr($_SERVER['SERVER_NAME']) ? $_SERVER['HTTP_REFERER'] : false);
if($referrer)
{
try
{
if(false !== ($resource = fopen($referrer,"r")))
{
$contents = '';
while($contents .= fread($resource,128))
{}
if(preg_match('/<title>(.*?)<\/title>/is',$contents,$found))
{
echo 'Referrer: ' $found[1];
}
}
}catch(Exception $e){}
}
