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 .

Hi there,

I am new to this forum want to say Hi  to everyone  .
I just learn a little bit of PHP. I couldn't figure this out. Could someone please help me? Many thanks.

1. when I ran the 1st code below, it showed me "thank you" in the browser.
    <?php
    $title=$_GET[title];
    echo $title;
    ?>

2. when I ran the 2nd code below, I got what I wanted.
    <?php
    $sql = "SELECT * FROM mytable WHERE title='thank you' ";
    ...
    ?>

3. when I ran the 3rd code below, it showed me a blank page  .
    <?php
    $title=$_GET[title];
    $sql = "SELECT * FROM mytable WHERE title='<?php echo $title; ?>' ";
    ...
    ?>

How to make the 3rd code work like the 2nd one? It seems a php code under php is NOT working.

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']);

}

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?

I have some javascript for a tabbed interface in index.php. The content of each tab is in content.php which uses $_GET to define which tab is selected. But i want to include queries based on variables from index.php how would i do this?

here is the code for the tabbed interface:

<script language="JavaScript" type="text/javascript" src="<?php echo SITE_ROOT; ?>/js/ahahLib.js"></script> 
<script language="JavaScript" type="text/javascript"> 
function makeactive(tab) { 
document.getElementById("tab1").className = ""; 
document.getElementById("tab2").className = ""; 
document.getElementById("tab3").className = ""; 
document.getElementById("tab"+tab).className = "active"; 
callAHAH('includes/content.php?content= '+tab, 'content', 'Loading...', 'Error'); } 
</script> 

<ul id="tabmenu" > 
<li onclick="makeactive(1)">
<a class="" id="tab1">Account Information</a>
</li> 
<li onclick="makeactive(2)">
<a class="" id="tab2">Second Page</a>
</li> 
<li onclick="makeactive(3)">
<a class="" id="tab3">Third Page</a>
</li> 
</ul> 
<div id="content"></div> 

and the code in content.php

if ($_GET['content'] == 1) { echo 'Content for Page 1'; } 

if ($_GET['content'] == 2) { echo 'Content for Page 2'; }

if ($_GET['content'] == 3) { echo 'Content For Page 3'; } 


ive tried adding the variable $user_id to the content.php url as follows:

callAHAH('includes/content.php?user=$user_id&amp;content= '+tab, 'content', 'Loading...', 'Error'); } 

but that just brought up an error.

I cannot seem to get my link to work.. I want to build a php script that has more than one $_GET command.. The link I want to make is: index.php?section=tutorial&viewing=18-classes_or_ids.
Here is my PHP code..

<?php
$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":
include("classesorids.html");
break;
}
?>

Please help me!!

I have a link (http://site.com/user/redirect). This link directs me to "site.com/user.php?level=site.com/123.php?hp=1"

How can I echo just "site.com/123.php?hp=1"?

I know how to use $_GET but I don't know how I can apply it to this.

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>';  ?>

how do i get the id from the url so i can use it

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.

Please i will like to know what this variable $_GET['id']is used for and how to use it
Thanks

Hi guys i am a PHP newbie trying to learn from the beginning. I am reading a php book and i can't get past a particular example because $_GET and $_POST just won't work. Below is the code i am working with:

HTML File
<form action="welcome1.php" method="get">
    <div>
     <label for="firstname">First name: <input type="text" name"firstname"
      id="firstname"/></label>
    </div>
    <div>
        <label for="lastname">
            Last name: <input type="text" name="lastname" id="lastname"/>
        </label>
    </div>
    <div>
        <input type="submit" value="GO" />
    </div>

PHP file

<?php
 $firstname = $_GET['firstname'];
 $lastname = $_GET['lastname'];
 print 'Welcome to our website, ' .
    htmlspecialchars($firstname, ENT_QUOTES, 'UTF-8') . ' ' .
    htmlspecialchars($lastname, ENT_QUOTES, 'UTF-8') . '!';
?>

I am working on a windows pc with Vista home edition installed. I run a localhost server installed via XAMMP. Please this has been a recurring problem for me. Each time i get to this stage in the past i always get stuck. $_GET and $_POST just does not work for me. Please heeeelp!

Do I need to escape variables passed via link? Is it possible that someone does an SQL Injection via unescaped $_GET variable? (Yes I am using it in an SQL query, not inserting it into a DB tho)

hey guys im having a bit of trouble getting $_GET in my framework. now the ony way to get query from a url such as:     users/activate-account?email_address=test&token=test    i have to use $_SERVER['REQUEST_URI'] unless im doing something wrong?     [REQUEST_URI] => /bisi/user/activate-account?email_address=test&token=test   by doing this:

print_r($_GET);

all i get is :     Array ( [uri] => user/activate-account )   just concerned im doing something wrong?...any advise on this please guys.   was thinking of doing something like this in my request

public function get_query($name = null)
	{
		$uri = $_SERVER['REQUEST_URI'];
	
		if (parse_url($uri, PHP_URL_QUERY))
		{
			$query = explode("?", $uri);
			$query = explode("&", $query[1]);
					
			$array = array();
				
			foreach ($query as $string)
			{
				$string = explode("=", $string);
				$query_name   = $string[0];
				$query_value  = $string[1];			
				$array[$query_name] = $query_value;
// $_GET[$query_name] = $query_value; possibly?
			}
				
			if ($name !== null &&
		        array_key_exists($name, $array))
			{
				return $array[$name];
			}
			
			return $array;
		}
		
		return null;
	}

thanks
