PHP - $_get Variable Goes To 0
Hello all,
I am terribly confused about the following code, for some reason $tourn keeps going back to 0 for no reason! This code: <?php include 'header.php'; $tourn = $_GET['extourn']; echo "first ".$tourn."<br />"; if($tourn=0){ echo "tourn1 is ".$tourn."<br />"; } else{ echo "tourn2 is ".$tourn."<br />"; } ?> returns this: Quote first 4 tourn2 is 0 While tourn2 should return 4 as well. I have tried a million different versions, including switches and everything and just can't understand it. Please help! Similar Tutorialshaving a problem using get variables to include certain pages. I have a management script for a news feed that uses get variables to display certain parts of the script. here is the template/ main part of the script <?php session_start(); require_once("vars.php"); $username = $_SESSION['username']; $is_admin = $_SESSION['is_admin']; $referer = $_SERVER['HTTP_REFERER']; //check to see if user is logged in and is an administrator if((isset($_SESSION['username'])) && ($_SESSION['is_admin'] == 1)){ //if all session variables are set, display admin panel ?> <html> <head> <title>Administration</title> <link rel="stylesheet" type="text/css" href="/cameo/css/admin.css" media="screen" /> </head> <body> <table cellspacing="0" cellpadding="3" class="layout"> <tr> <td colspan="2"><h3>Administration</h3></td> </tr> <tr> <td valign="top"> <a href="index.php?pg=news">Manage News Feed</a> </td> <td> <?php $id = $_GET['pg']; switch($id){ case news: include("manage_news.php"); case editpost: include('edit_post.php'); break; } ?> </td> </tr> </table> </body> </html> <?php } else { echo("You do not have permission to view this page. <br />"); echo("<a href=\"".$referer."\">Go Back</a>"); } ?> and heres the edit post page that the script refers to <?php require_once("vars.php"); $id = $_GET['id']; $query = "SELECT * FROM news_feed WHERE id=".$id; $result = mysqli_query($dbc,$query); $row = mysqli_fetch_array($result); ?> <form method="post" action="update.php"> <textarea><?php echo $row['post_body']; ?></textarea> </form> now, for some reason, the edit post form is showing up under the main news feed listing, even though the get id does not match the one in the switch statement. thanks in advance for any help Hello! I was wondering if this could be done... I want to take a variable, and insert it into a URL for a $_GET on a different page? Basically Its a member website, and I want the admin to be able to "accept" or "deny" the application... So i have a page that displays all the applications, and I want it to take him to a different page with all the user's information in detail. Right now it only displays their name, but when the admin presses the link, it takes them to a more detailed page about the applicant, where they can then "accept" or "deny" the application.... Here is what i got so far... Code: [Select] $character_name = "Nightmareinhell"; <a href="admin_evaluate.php?name=$character_name">$character_name</a> Here is the error I get from the code above Quote Parse error: syntax error, unexpected T_STRING in C:\wamp\www\admin_acceptapply.php Thanks to any help!!!! I have coded a database and I dont like how the user can edit the titles through the get variable. Is there anyway I could stop that? Wouldnt getting each request from the database slow down the site? <?php include "config.php"; include "functions.php"; $SITEURL = addSlash($SITEURL); $action = $_GET['action']; $state = $_GET['state']; $city = $_GET['city']; $id = $_GET['id']; echo $SITEURL; switch($action) { case 'cities': include 'templates/cities.php'; break; case 'place': include 'templates/place.php'; break; case 'places': include 'templates/places.php'; break; default: include 'templates/home.php'; break; } ?> #places.php <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title><?php echo $siteTitle; ?></title> </head> <body> <h2><?php echo $SITETOPIC." in ".$city.",".getStateName($state); ?></h2> <?php $query = "SELECT DISTINCT biz_name, biz_id FROM animalshelter WHERE city = '".$city."'"; $result = mysql_query($query) or die(mysql_error()); while ($row = mysql_fetch_array($result)) { echo "<a href=http://".$SITEURL."place/".$state."/".urlencode($city)."/".$row['biz_id'].">".$row['biz_name']."</a><br />"; } ?> </body> </html> #.htaccess # .htaccess mod_rewrite # demo.com Options +FollowSymlinks Options +Indexes RewriteEngine On RewriteBase /databaseSite/ ErrorDocument 404 /templates/404.php RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-l RewriteRule ^([a-zA-Z]+)/([a-zA-Z]+)$ index.php?action=$1&state=$2 [QSA,NC] RewriteRule ^([a-zA-Z]+)/([a-zA-Z]+)/([a-zA-Z\+\_\-]+)$ index.php?action=$1&state=$2&city=$3 [QSA,NC] RewriteRule ^([a-zA-Z]+)/([a-zA-Z]+)/([a-zA-Z\+\_\-]+)/([0-9]+)$ index.php?action=$1&state=$2&city=$3&id=$4 [QSA,NC] The code below works echo '<script language="javascript">'; echo 'top.location.href = "/breaking-news/bsnewsstorygoeshere/";'; echo '</script>'; this also works echo '<script language="javascript">'; echo 'top.location.href = "http://anywebsite.com";'; echo '</script>'; the problem, is I have a URL listed in a url variable that can be retreived via $_GET['url'] my question is how to get that variable into the above code? I've tried echo '<script language="javascript">'; echo "top.location.href = \"$_GET['url']\";"; echo '</script>'; but that doesnt seem to work, can anyone advise? User clicks on a url, ie: example.com/AEQ438J When I perform this in the code below: Code: [Select] $referrer = $_GET['_url']; // echo $referrer displays the referrer ID contents correctly as "AEQ438J" if ( ! empty($referrer)) { $mysqli->query("UPDATE coming_soon_emails SET clicks = clicks + 1 WHERE code='" . $referrer ."'"); } // this also updates the database correctly as it should if (!empty($_POST['email'])){ // echo $referrer displays the referrer ID contents as BLANK. It should display "AEQ438J"! ..... $referrer displays correctly BEFORE if($_POST['form']), however during the if($_POST['form']) $referrer is empty. How can I fix my code so that $referrer is not empty during the time the user posts their email address in the form? Thank you!

I am seen people have dynamic pages that loads the information from a database and then displays that information from the url. EG domain.com/somedirectory/something I have a website that does this but uses domain.com/something.php?id=something . This works great but when I go to try and get the statistics for that page from facebook for number of people that have liked that page. When I go to: http://graph.facebook.com/http://likebook.cz.cc/ It shows me the information: Code: [Select] { "id": "**************", "name": "LikeBook", "picture": "http://profile.ak.fbcdn.net/hprofile-ak-snc4/hs178.ash2/41817_130259343675613_3465_s.jpg", "link": "http://www.facebook.com/pages/LikeBook/130259343675613", "category": "Website", "description": "Collect every like at LikeBook.cz.cc", "fan_count": 3 } But when I try and go to: http://graph.facebook.com/http://likebook.cz.cc/like.php?id=31 It shows me: Code: [Select] { "id": "http://likebook.cz.cc/like.php" } So what I need to do is. Make a dynamic page within that sub directory. So that http://likebook.cz.cc/like/31 does grabs the information from line 31 of my database, like http://likebook.cz.cc/like.php?id=31 would do. Thank you ~AJ I am really confused about how people use $_GET to give a page a link so far what I understand is that $_GET grabs the information from a link So if my link was http://localhost/stargate/users/profile.php?goauld=Sam how do I turn this into viewing Sams profile soon as i type in that link with out having to hit a search button first would really appreciate if someone help me understand this please cause it appears i really need to know how to do this. Code: [Select] <?php if(isset($_POST['search'])) { // searches goaulds then displays them $search3 = "SELECT goauld,id FROM users WHERE goauld='".mysql_real_escape_string($_POST['goaulds'])."'"; $search2 = mysql_query($search3) or die(mysql_error()); WHILE($search1 = mysql_fetch_array($search2)){ $grab_goauld = $search1['goauld']; echo '<table width="300" height="5" border="1" align="center">'; echo '<th><center>Goauld Statistics</center></th>'; echo "<tr><td height='340'>$grab_goauld</td></tr>"; } } echo '</table>'; ?> I have javascript to load to my div the contents from php files something like this: QueryString is an addon javascript file loaded above so it works.. var get_id = $.QueryString["id"]; switch(get_id){ case 'page1': $('#div').load('php.php'); break; } on php.php when i try to get the $_GET['id']; which is obviously 'page1' it cant display it... i get nothing , i use switch in order to create dynamic div so i can click in my links and just load the divs content thanks.
