PHP - Hiding $_get Variables

A few months ago, and a good amount of time before that, I had people telling me to use isset() instead of performing to see if the variable is empty, such as: !$_GET['']

I know the differences in the function and what they do, but when could isset() be used in a situation where it's better/more efficient then: !$_GET['']

I do use isset(), though.

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 people!
I have this code:
if ($_POST['remember'] == true)
                        {
                                // COOKIES ON!
                                $time = time() + 20000;
                                setcookie(user, $username, $time);
                                setcookie(pass, $password, $time);
                                header("Location: index.php");
                                echo "<h1 class='welcome'>Welcome ".$_COOKIE['user']." |</h1>";
                                echo "<div id='divlogin' style='visibility:hidden'></div>";
                                echo "<a href='logout.php'><h1 class='logout'><b>Logout</b></h1></a>";

                        }elseif ($_POST['remember'] == false){

                                echo "<div id='divlogin' style='visibility:hidden'></div>";
                                echo "Div hidden!";
                                                }
"remember" - is a checkbox.
So, if the checkbox is checked then I will activate the cookies and hide the divlogin (till now everything is fine), but if the checkbox isn't checked, I will just hide the divlogin (and this don't happen), however, the echo "Div hidden!" works nicely. The code detects if the checkbox is checked or not, the only problem is that if isn't checked the div doens't hide.

Any ideas? 

Thanks 

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

$section = $_GET['section'];
switch ($section)
{
case "home":
include("home.html");
break;
case "register":
include("register.html");
break;
case "tutorial_home":
include("tutorial.html");
break;
default:
include("home.html");
}
$tutorial = "?section=" .  urlencode('tutorial&viewing') . $_GET['tutorial&viewing'];
switch ($tutorial)
{
case "18-classes_or_ids":

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.

I never really thought about it before, but recently I visited a site with a url like:

www.example.com/?OR

Which made me wonder how you would go about getting that keyname since it is without a value. Any ideas?

how would i get this to work
if they have click on the add page and the action is add i want it to do something how would i do it

Code: [Select]
<?php
if(isset($_GET['action'])){


}
?>

<a href="pages.php?action=add">Add Page</a>

Hi I am trying to use 2 codes to get a url link.

code1 (test.php):

    <form action="test1.php" method="GET" />
    link: <input type="text" name="link" /><br />
    <input type="submit" value="Submit" />
    </form>



code2 (test1.php)

    <?php
    $link = $_GET['link'];
    echo $link;
    ?>



If I input a link as a text such as "Yahoo" it works. But if I input a link as "http://yahoo.com", it didn't work .

I am a new programmer. I am working on a personal project for my portfolio, it is a simple blog.
I am trying to give the user the ability to delete a blog entry. It works fine, the problem is that
when you refresh the page, with out clicking 'delete' the entry is still deleted. $_GET is passing
the $id to my function and it is executing. The code I have posted is my effort to fix the problem.

How can I connect $_GET to the delete button ? I have tried using a hidden value but this is not working.

Any help would be greatly appreciated.
AL


Code: [Select]
// code to display message before deletion
if($_GET['T'])
{
echo("<div style='float:right; width:25%; height:100px; position:absolute; top:150px; right:15%;'>");
echo("<h2>Are you sure you want to delete:<h2>");
echo $_GET['T'];
echo("<form method='get' action='?'>");
echo("<input type='submit' name='button' value='Delete'>");
echo("<input type='hidden' name='submit_check' value='1'>");
echo("</form>");

echo("<form action='http://nuke.industry.com/Blogspiracy/UserPage/index.php'>");
echo("<input type='submit' value='Cancel'/>");
echo("</form>");
echo("</div>");
}

// code to delete a selected blog entry
function delete_blog($id)
{
global $dbh;
$sql = "DELETE FROM tblBlog WHERE tblBlog.id = '$id' LIMIT 1;";
$sth = $dbh->prepare($sql);
$sth-> execute();
return;
}

if (isset($_GET['id']) && ($_GET['submit_check']))  how do I "GET" the hidden value?
{
$remove = delete_blog($_GET['id']);

}
