PHP - How To Get Just Referrer Url And Not All The Variables?

I'm trying to redirect visitors that contain broadly matched URLs. For example, redirect the visitor if their url contains: "/welcome" or "order.php" or "login.mysite/"

At the same time I also want to redirect the user if they a particular User Agent.

Here's what I have, but doesn't seem to be entirely working...

Code: [Select]
<?php

//detect referrer
$ref = $_SERVER['HTTP_REFERER'];
$find = "order.php";
$find = "login.mysite/";

//setting the variables
$linux = stripos($_SERVER['HTTP_USER_AGENT'],"Linux");
$aol = stripos($_SERVER['HTTP_USER_AGENT'],"AOL");

//detecting user agent device, os, browser, etc.
if ($linux == true || $aol == true) $redirect = 1;

//detect referrer
elseif (preg_match($ref, $find)) $redirect = 1;

//set redirects
if ($redirect) {
    $url = "http://www.google.com";
} 
else {
    $url = "http://www.yahoo.com";
}

header("Location: $url");

?>
Any help you can offer is appreciated. Thanks!

Hello,

I need a small php script to ping a domain with custom referrer url

eg: I need a script to ping a website www.abc.com with a custom referrer url ie. xyz.com

so that the website abc.com would think that the traffic is from xyz.com


Anyone have an idea?

Hi, I have decent knowledge of htaccess and know enough about php/mysql so a little direction/advice is mostly what I need. I host a website(site1.com) that has links to files that are hosted on a different website(site2.com) on a different server. When a file link is clicked from site1.com, first it will go to a local php file(within site1.com) that checks that the user is logged in and make sure the file exists. Then it redirects(using a simple header function) to the file located at site2.com to begin download.

But since my files at site2.com stored in a simple folder(if you knew the folder name, you could download all the files without having to be logged in), I want a way for site2.com to check that the file request is coming from site1.com(maybe using php referrer?) before it allows the download to proceed. Any ideas?

does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

Code: [Select]
$xml='<?xml version="1.0" encoding="utf-8"?>

Hi. I have some code which needs to return a single variable from the function and stored as a variable within this page, so it can be echoed later on in the page. I couldn't get it to return as a variable, so i used "return compact();" to return the variable and "extract (myFunction());" to extract it to variables. However, when I turned on php's display errors and error reporting function, I got an error message saying "Warning: extract() [function.extract]: First argument should be an array in /my/web/site/index.php on line 6" (which is where my extract function is). This works fine with passing more than one variables through, is there another way pass one variable from a function to be stored as a variable on the page which called the function?

Here is the function:
Code: [Select]
<?php
//This is a list of numeric error codes against their text. this will return the error code as the variable $issue
function checkLoginIssue() {

//If there is an error code
if (isset($_GET["issue"])) {
 
  //cycle through the list until the code is reached, return the text and break the switch
    switch ($_GET["issue"]) {

      case "1":
              $issue = '<p class="warning">Please log in to view this page</p>';
              break;
  
      case "2":
              $issue = '<p class="warning">Wrong Username or Password</p>';
              break;

        case "3":
              $issue = '<p class="warning">No user found with those details</p>';
              break;

    }
 
 //return the variable in an array with a single value
 return compact('issue');
 
}
 
}
?>
And here is the code which calls the function:
Code: [Select]
<?php
extract(checkLoginIssue());
?>

I've got a select statement that looks like this in php.
Code: [Select]
$sql = "Select * from inventory where ".$fields."".$operator."".$criteria;
Everything posts correctly, everything is dereferenced correctly.    My only question is how do I get $criteria have single quotes around it?

So that when I actually run the query it says

select * from inventory where field = 'value';


I've tried
Code: [Select]
$sql = "Select * from inventory where ".$fields."".$operator.""'.$criteria';

$sql = "Select * from inventory where ".$fields."".$operator.""'$criteria';
and a bunch of variations like that. 

Thanks for you help.

Hello,
Is it possible to use variables that are declared outside or plainly within a class, and if its possible, how?
thanks in advance

Hi guys,

I've a developer for a pretty large website and forum, the database is exploding in size and we are now seeing a grow in the slow log. We want to be able to fix this by optimizing query's but the site is so big, we can't locate the query's themselfs as they are dynamically generated.

I want to be able to tail onto the end of the query a comment containing where a function was last called. In the example below, I want the file name and line-number of where add_together() was called.

Here is an example for index.php:

Code: [Select]
$a = 1;
$b = 2;

$c = add_together($a, $b);

function add_together($a, $b)
{
    return $a + $b;
}

Look forward to your assistance with this!

Joe

It echos that there are to many.. how would I do this

Saying like if I had 100 $Variable[] it would echo that there are to many?

$Variable[] = "";
$Variable[] = "";
$Variable[] = "";
$Variable[] = "";
$Variable[] = "";
$Variable[] = "";

Hi,

Which one is better from performance view (CPU usage and etc)? using too many Variables or a single Associative Array or generally an Array?

This one:

$ld_linkdump_title         = get_option('ld_linkdump_title');
$ld_linkdump_widget_title  = get_option('ld_linkdump_widget_title');
$nw_option                 = get_option('ld_open_nw');
$ld_open_branding          = get_option('ld_open_branding');
$ld_stylesheet_option      = get_option('ld_stylesheet');
$ld_number_of_links        = get_option('ld_number_of_links');
$ld_number_of_links_widget = get_option('ld_number_of_links_widget');
$ld_number_of_rss_links    = get_option('ld_number_of_rss_links');
$ld_number_of_links_be     = get_option('ld_number_of_links_be');
$ld_repeated_link          = get_option('ld_repeated_link');
$ld_linkdump_fd            = get_option('ld_linkdump_fd');
$ld_linkdump_rss_desc      = get_option('ld_linkdump_rss_desc');
$ld_branding_bg            = get_option('ld_branding_bg');
$ld_archive_days           = get_option('ld_archive_days');
$ld_archive_pid            = get_option('ld_archive_pid');
$ld_show_counter           = get_option('ld_show_counter');
$ld_show_description       = get_option('ld_show_description');
$ld_show_description_w     = get_option('ld_show_description_w');
$ld_send_notification      = get_option('ld_send_notification');
$ld_auto_approve           = get_option('ld_auto_approve');
$ld_short_url              = get_option('ld_short_url');


or this:


$options['ld_linkdump_title'] = get_option('ld_linkdump_title');
$options['ld_linkdump_widget_title']  = get_option('ld_linkdump_widget_title');
$options['nw_option']                 = get_option('ld_open_nw');
 .

I am not sure how to do the below, would variable variables be the way -- those are a new and confusing thing for me :-/

i have an array:

$contactData = array('admin_firstName' => 'John', 'admin_lastName' => 'Smith', 'user_firstName' => 'Betty', user_lastName => 'Jones'); 

I have a function that little function that looks like this:

function compare($contactSet, $var, $value){

global $contactData;

    $key = $contactData . "['" . $contactSet . "_" . $var ."']";
    //above doesnt work, but you can see how the array key is constructed
    
if ($key == $value) { 
// So, if the array key varied it would look like:
// if ($contactData['admin_firstName'] == $value

echo "same";

} else {

echo "different";

}

}


and then I want to call it like this:
compare('admin', 'firstName', 'John'); //would echo "same";

Any help is greatly appreciated. I have often wanted to use variable variables, or whatever this would be called, but don't know to pull it off. I can add another example if this wasnt clear enough.

I am trying to allow users of a web page the ability to create custom Excel exports. I have some code that I use elsewhere that works to make Excel exports. When I moved the code over to my custom report page, the Excel chart contains an error saying that $csv_output is undefined and so is $data (both variables toward the end of the page).

Hey there!
Thanks for taking the time to read my thread.

So basically I have one index page that handles all the redirects of the content etc but the issue is there can be any number of $_GET variables in the URL.

For example:

index.php?v=my-account&action=password&change=true&and=hello&there=yes


But how would I be able to use a rewrite rule to change all vars in the url at once to appear like this:

index.php/my-account/action/password/change/true/and/hello/there/yes

Thanks for your time!

Can I use a variable inside an sql query to determine which table to select from? The 2 functions below do exactly the same thing, they're just selecting data from different tables. I'm not sure how I can do it. Maybe put a parameter in the function & use sprinf?


// Output the page data
function showpages()
  {
   db_connect();
$query = ("SELECT * FROM pages");  // can I change pages to a variable somehow?
$result = mysql_query($query);
    $result = result_to_assoc($result);
    return $result;   
   }

// Echo the pricelist data into the pricelist form
function show_pricelist()
  {
db_connect();
$query = ("SELECT * FROM pricelist");  // Again, if pricelist can be a variable, then I need only 1 function
$result = mysql_query($query);
    $result = result_to_assoc($result);
    return $result;   
   }

Hi all,

I have been coding in PHP for a fair while now and I have come across variables by reference, but I don't really know:
a) how they work;
b) when to use them;
c) why they are used;

Can anyone here please clarify these issues please.

Thanks in advance!

Hello,

I'm try (for the first time!) to pass two variables between two pages, namely,  $_GET['assignment_id'] (generated from the last page) and $row['question_id'].  From what I understand, I need a "&" to join the two variables.  Unfortunately, my code isn't working: might there be some sort of concatenation or extra quotes that I need to get things rolling?

Thank you for your help.

Code: [Select]
<a href="../main_scripts/db_insert_assignment_question.php?question_id=<?php echo $row['question_id']&assignment_id=$_GET['assignment_id']; ?> Code: [Select]
">Add Question</a>

sorry there is so much code, but how can I make it so that the flash upload piece of this will be able to send variables, such as file name, to upload-file.php.....so that things can go into my database.  does this make sense?  if you need a working example, tell me and I will send you a PM with the address (don't want too many people knowing where this happens at......

Hi,

I'm looking through some code I have for setting up a rating system. It was a free open source code, which I need to change to work for my own site. I have it working, but I am now just looking through the code to try and understand it, and for the most part, I do.

There is one part I am not familiar with, if somebody could help me please?

Values involved;
$current_rating = total rate value of votes
$count = total number of votes cast

Problem I have is the @ symbol here
$rating=@number_format($current_rating/$count, 1);

Does it format it to decimal places or something like that? It's probably something simple I know, but I am a relative newb.

Thanks.
