index.php=id? ????

[La_Parka]

I've seen various pages that have everything based on an index.php page and the other pages are accessed as 'ids.' What is this system called, and what are the positives/negatives of using it?

[xentrix]

It works on the principle which I described in this thread:
http://www.phpbuilder.com/board/showthread.php?s=&threadid=10209003

Mostly, when you use variables called "id" it could mean that you use a database in which you have some articles (for example) and every article has its own id number - that´s the "id" you call in URL.

some languages are based on a BIG CGI component that will be call with a wide variety of different query strings and you will never leave this CGI component (WebDev for example) PHP allows you to develop the way you want
you can cut your app in many little scrips that will call eachothers or have a big one and slap yourself in a year for the maintenanbility is very poor...

I saw this on another message board. This is an example of what I'm talking about.

<center>
<a href="<?=$PHP_SELF;?>?id=foo">Foo</a> - 
<a href="<?=$PHP_SELF;?>?id=bar">Bar</a>
</center>
<hr>
<center>
<? echo $_GET['id']; ?>!
</center>

this code will probably not work...

$GET is the wrong one it's $REQUEST...

Now let's say I use a script like that hypothetically, and put a random image script into the shared portion. Will that reload each time I go to a new id page, or will it remain static?

[psy]

if its in the shared portion, it will reload each time a var is passed (id in this case)and if its for a random image, just seed the generator before you randomize and it should be fine

for additional info on the index.php?id=x check these this out

This is starting to annoy me! I have this particular section of the page divided into a 3-columned table. The left cell has my navbar, the center has my variable content, and the right cell will be used for PHP scripts later on 😉, but whenever I add the HTML in, it pushes the position of the navbar down! arrghh!:mad:

Uh, no?
$_GET will work.

Say I have this ID structure using seperate files for each ID, so each ID calls up a .htm in one of the tables on the page while the rest of the page remains the same. Is there any way I can have the page titles change accordingly with the <TITLE> tag remaining at the top of the page?

Note: The part of the page that changes for each ID is located in the middle of the page, so it is not near the head.

[Bunkermaster]

switch( $ID ){
case "blah":
echo "<title>This is about the blah thingy</title>";
break;
....

then when you want to have the diff html (???) file included :
include( "myinclude.$ID.php" );

[philipolson]

Here's an example SQL query:

$sql = "SELECT firstname, lastname, email FROM users WHERE id='{$_REQUEST['id']}'";
if (!$result = mysql_query($sql)) {
    print "Invalid query ($sql) : " . mysql_error();
    exit;
}
while ($row = mysql_fetch_assoc($result)) {
    print "Hello {$row['firstname']} {$row['lastname']}, how are you?";
}

So, this page selects all information associated with that ID and will show it. Same can be fore a video game id, a book id ... the possabilities are endless. Regarding includes based on a variable, maybe:

$includedir = 'includes/';
$filename = $includedir . 'inc_' . $_REQUEST['id'] . '.inc.php';

if (file_exists($filename)) {
    include $filename;
} else {
    include $defaultinclude;
}

$GET is only ?this=that variables. $REQUEST also includes form ($_FORM) variables.

[philipolson]

Please read the manual entry on $_REQUEST, it's a mix of GET, POST, and COOKIE.

Also, read this faq as it deals with this question:
http://www.faqts.com/knowledge_base/view.phtml/aid/5424

[JohnM_2000]

Yes.

[slipspace]

Using the following code :

<?php
$defaultinclude = 'include/1.inc.php';
$includedir = 'include/';
$filename = $includedir . $_REQUEST['id'] . '.inc.php';

  if (file_exists($filename)) {
       include $filename;
  } else {
       include $defaultinclude;
             }

?>

<!--- end code -->

and the following links :

<a href="test.php?id=2">ID 1 </a><br>
<a href="test.php?id=3">ID 2 </a><br>

Works great, exactly what I am looking for... Except, I would like to make the link appear into an iframe.

Simply placing the target frame in the link doesn't seem to work.

ie
<a href="test.php?id=1" target="_inline">ID 1 </a><br>

Help on this or a better routine for this type of id referencing navigation is greatly appriciated!
