Hi,
I want to know wich alternatives there are instead of Iframes?
I want to make something with PHP. Is that possible?

I have a navigation menu, and a small Iframe place for a bit of content...
Now I want to get rid of that Iframe and replace it by a PHP include or sorth of thing...
So the content in that DIV changes into other things by clicking on the links in the other DIV.

 
<div id="nav">
<a href="" target="fraim">link1</a><br>
<a href="" target="fraim">link2</a><br>
<a href="" target="fraim">link3</a><br>
</div>

<div id="smallcontent">
<iframe src="blanco.html" name="fraim" width="200" height="200"></iframe>
</div>

Any help?
Thanks,
Bulevardi

I'm assuming that you meant that you want to just use that page as a template for all of the pages that would come into the iframe. In which case I'd do something like this:

PHP Code:

//top of page stuff...

<a href="/?link=1">Link 1</a>
<a href="/?link=2">Link 2</a>
<a href="/?link=3">Link 3</a>

<?php
$linkno = (isset($_GET['link'])) ? $_GET['link'] : 0;

include('content' . $linkno . '.htm');
?>

// rest of the page

This will look to see if the user got to the page through one of the links. If they did then it will load the relevant content page (content1.htm, content2.htm...) directly into the document before it is sent to the browser. If they've not it'll load content0.htm.
Hope this helps, Tom

I'm no expert on iframes or PHP, but here's a post that might help, courtesy of Dansgalaxy:

http://www.webmaster-talk.com/html-f...tml#post448484

And something like this won't work?
I'm still learning the basics of PHP

 
<a href="<?php $linkno . '1' ?>" target="content">Link 1</a>
<a href="<?php $linkno . '2' ?>" target="content">Link 2</a>
<a href="<?php $linkno . '3' ?>" target="content">Link 3</a>
 
<div id="smallcontent">
 
 
<?php
include('content' . $linkno . '.htm');
?>
 
</div>

I don't understand that isset and $_GET thing very well...

if you are wanting to update just that div without refreshing the page, AJAX is what you need. Prototype is a good js framework with easy ajax functions.

If you're wanting to refresh the whole page...your last post is totally off.

Here is some code w/ some comments to try to make things clear for you.

PHP Code:

// switch statement. this takes in the url parameter 'page' and 
// does crap accordingly. You can have as many different cases as you need
// Note: $HTTP_GET_VARS is safer than $_GET
// because it escapes possible malicious code.
switch ( $HTTP_GET_VARS['page'] )
{
case "1": // if ?page=1, this sets $page to 'page_1.php'
    $page = 'page_1.php';
    break;
case "2":
    $page = 'page_2.php';
    break;
case "3":
    $page = 'page_3.php';
    break;
defaut: // if ?page doesnt = 1,2, or 3, this sets $page to 'main_page.php'
    $page = 'main_page.php';
}

<div id="content_area">
   // include the proper page from your includes directory
   include ( 'includes/' . $page ); 
</div> 


something like that should work. you may want to read up on the switch statement: http://php.net/switch

I just noticed you asked about isset() and $_GET:

$_GET: a predefined variable http://us3.php.net/manual/en/reserve....variables.get

There are many ways to pass information from one php page to the next. $_GET is one of them. It is simply an array of the url parameters in the query string of the url.

Example:
if your url was http://www.mysite.com/index.php?page=contact

PHP Code:

echo $_GET['contact']; // will output the word 'contact' 


isset ( ): http://php.net/isset
isset() checks to see if a variable is set or not.

Example:

PHP Code:

if ( isset ( $_GET [ 'page' ] ) )
{
    echo "the page parameter is set in the url";
}
else
{
    echo "the page parameter is NOT set";
}

isset() checks that the variable is set, NOT if it is empty or not 


Thanx bhgchris !

But can you get a php function out of a link - like in javascript:

 
<a href="<?php openpage1() ?>">link</a> 
 
And than the function opens includes, like:
 
<?php
function (openpage1) {
include "page1.php"; 
}
?>

This would be a super solution, but it's not working.


Otherwise, I found something like this somewhere... :

 
<a href="?load=page1">Go to page 1</a> 
<a href="?load=page2">Go to page 2</a> 
 
<?php 
if($load ==  "page1") { 
include "page1.php"; 
} 
elseif($load ==  "page2") { 
include "page2.php"; 
} 
else{  
include "errors/fout404.php"; 
}  
?>

In this case, do you have to use this isset thing too?
Cause I'm still not getting the isset issue. Is it just to define '$load' ? like in javascript 'var' ?

 
<?php 
if(!isset($_GET['load'])) {  
$load = "page1";  
}
else {  
$load = $_GET['load'];  
}  
?>

First, thanks whym

isset is to check if its set as said before, its used as means of validation.
in my case in the script whym posted. its used because if it isnt set it shows aother page.
so you could have a simple thing like

PHP Code:

$divpage = $_GET['div'];
 
$divpage = (isset($_GET['div']))   ?   $_GET['div'] : 'default_div_content.php';
 
echo '<div>';
include ('pages/'.$divpage.'.php');
echo '</div>'; 


before you ask this:

PHP Code:

$divpage = (isset($_GET['div']))   ?   $_GET['div'] : 'default_div_content.php'; 


would do exactly the same as:

PHP Code:

if(isset($_GET['div']))
{
$divpage = $_GET['div'];
}
 
else {
$divpage = 'default_div_content.php';
} 


its just another way to do it.

Hope this helps.

Don't trust external data.

isset() performs no validation, I would never dump the contents of a GET var stright into a process without validating it first. A switch does; if the incoming data doesn't comform to one of the cases, a default value can be used.

A switch or an array will do the job nicely. For eg.

Typically I use 3 steps to load includes based on a GET var. Step 1, validate the get var, step 2, check that the include exists, step 3, include the corresponding file.

script: includes/inc_functions.php

PHP Code:

//dual purpose: return bool (true/false) GET var is an index of includes array
//                return string of path/filename to include
function includePage($pageName, $validKey = true) {

    //add items to include array as required
    //associative index = string preceding extension full-stop
    //value = relative path to include from root
    $arr_includes['page1'] = 'includes/inc_page1.php';
    $arr_includes['page2'] = 'includes/inc_page2.php';
    
    if($validKey) {
    
        $returnBool = array_key_exists($pageName, $arr_includes);
        return $returnBool;
    
    } else {
        
        //grab include path from array and test if it exists
        $include_path = (@file_exists($arr_includes[$pageName])) ? $arr_includes[$pageName] : false;
        
        return $include_path;
    
    }
} 


html: includes/inc_page1.php

<p>The qwik brown fox jumped over the lazy page one.</p>

html: includes/inc_page2.php

<p>The qwik brown fox jumped over the lazy page two.</p>

html: includes/inc_page_error.php

<p style="color: #FF0000">Error: Page does not exist or has been archived.</p>

Tying all files together to toggle the include.

script: content.php

PHP Code:

<?php 

include_once('includes/inc_functions.php');

$thisPage = (!empty($_GET['page'])) ? $_GET['page'] : false;
$validPage = false;

//default page to load if GET var is invalid
$includePage = 'includes/inc_page_error.php';

//validate GET var for page
if($thisPage) {

    $validPage = includePage($thisPage, true);
    
}

//if valid page, overwrite default includePage
if($validPage) {
    
    $includePage = includePage($thisPage, false);
    
}    

?>
<html><head>
<title>Test Includes</title>
</head>

<body>
<div id="content">
<?php include_once($includePage); ?>
</div>
</body></html>

function includePage() performs get var validation, file_exists() validation and if everything validates returns the appropriate include.

when i said validates i ment it validates if it exists, i was using the term loosly.

and i went for the sort and simple way, i assumed he would expand on it himself.
