Query string in URLs

Question

I tried looking on Google for info on this, but not much came to light.
I'm trying to do a query string that takes info from text files and renders them as PAGENAME.php?id=1 - without using a database, if possible.

My file is called test.php and this is its content:

<html> 
<body> 
<?php 
print("<B>This is 100 FM for North Loamshire. Info coming soon</B>"); 
?> 
</body> 
</html>

However, I would like to make pages in the format test.php?id=1, test.php?id=2, similar to how http://www.brmb.co.uk/schedule.asp is http://www.brmb.co.uk/schedule.asp?id=1

I know ASP and PHP are totally different, but the idea's the same - using a query string.

If anyone could help me it would be much appreciated. :icon_cheesygrin:

Hey,

What are you really trying to do? Are you trying to display different information on a page based on query string provided in url? If yes you could simply do this:

- when calling page: test.php?id=1

<html>
<body>

<? if($_GET['id']==1){ ?>
here comes the content for id #1
<? }else if($_GET['id']==2){ ?>
here comes the content for id #2
<? }else if(!is_numeric($_GET['id']) || $_GET['id']<1){ ?>
invalid id (or page not found)
<? } ?>

</body>
</html>

if you are trying to load the content from the text file you could simply substitute the php code with:

<?
$contents = file_get_contents('./text_file_'.$_GET['id'].'.txt', true);
if($contents)  print $contents;
else               print 'Page not found';
?>

which would load contents of text file located in the same directory named: text_file_1.php for id=1 etc...

Good Luck

//make it TAB delimited file

$thefile = "test.php" 

$fd = fopen ($thefile, "r");
while (!feof ($fd))
{
   $buffer = fgets($fd, 4096);
   $lines[] = $buffer;
}
fclose ($fd); 

//THE FIRST REFERENCE NUMBER INSIDE THE FILE SUBMITTED
$TheFirstRecord=trim($lines[0]);
$RefNum = explode("\t", $TheFirstRecord); //detect the TAB to explode

then put every $Refnum[] array value in your code.

If you do something like this:

<?php
$Day = date('N');
?>

This would return the number of the day E.G.
Monday = 1
Tuesday = 2
..
Friday = 5
..
Sunday = 7

Thanks to all for that - my site should work properly now.
One more question... I'm planning to use a switch statement so that it shows the correct page on certain days.

This is my code:

<html>
<body>

<? if($_GET['day']==1){ ?>
 <?php include("day1.php") ?>
<? }else if($_GET['day']==2){ ?>
 <?php include("day2.php") ?>
<? }else if($_GET['day']==3){ ?>
 <?php include("day3.php") ?>
 <? }else if($_GET['day']==4){ ?>
 <?php include("day4.php") ?>
 <? }else if($_GET['day']==5){ ?>
 <?php include("day5.php") ?>
 <? }else if($_GET['day']==6){ ?>
 <?php include("day6.php") ?>
 <? }else if($_GET['day']==5){ ?>
 <?php include("day7.php") ?>
<? }else if(!is_numeric($_GET['id']) || $_GET['id']<1){ ?>
invalid id (or page not found)
<? } ?>

</body>
</html>

Thanks for that. How would I use it with my code:

<html>
<body>

<? if($_GET['day']==1){ ?>
 <?php include("day1.php") ?>
<? }else if($_GET['day']==2){ ?>
 <?php include("day2.php") ?>
<? }else if($_GET['day']==3){ ?>
 <?php include("day3.php") ?>
 <? }else if($_GET['day']==4){ ?>
 <?php include("day4.php") ?>
 <? }else if($_GET['day']==5){ ?>
 <?php include("day5.php") ?>
 <? }else if($_GET['day']==6){ ?>
 <?php include("day6.php") ?>
 <? }else if($_GET['day']==5){ ?>
 <?php include("day7.php") ?>
<? }else if(!is_numeric($_GET['id']) || $_GET['id']<1){ ?>
invalid id (or page not found)
<? } ?>

</body>
</html>

Whenever I used it, it gave errors for me, but that's because I'm new to PHP! I'm past the beginner's stage, but still learning...

use switch my friend...

$i=$_GET['day'];


switch ($i) {
case 0:
    include("day0.php");
    break;
case 1:
    include("day1.php");
    break;
case 2:
     include("day2.php");
    break;
.
.
.
.
.
case 7:
      include("day7.php");
    break;
default:
    echo "page not found!!!!";
}

Thanks, rm_daniweb, that worked very well!
One question - how do I get it to automatically show the right page on the right day, e.g. it show's day 1's page on Monday etc. without people having to manually go to the URL , e.g. http://www.mysite.com/schedule.php?day=1

Hi

By using the below code it will automatically take your user to the page corresponding to the date given in the $day variable.
Try it first though because i'm very tired and should be asleep. I've probably made a simple mistake :P

Hope this helps anywho

<html>
<body>

<? 
if (!$_GET['day']) {
$day = date('N');
header('Location: http://www.yourwebsite.com?id=$day');
}
elseif($_GET['day']==1){ ?>
 <?php include("day1.php") ?>
<? }else if($_GET['day']==2){ ?>
 <?php include("day2.php") ?>
<? }else if($_GET['day']==3){ ?>
 <?php include("day3.php") ?>
 <? }else if($_GET['day']==4){ ?>
 <?php include("day4.php") ?>
 <? }else if($_GET['day']==5){ ?>
 <?php include("day5.php") ?>
 <? }else if($_GET['day']==6){ ?>
 <?php include("day6.php") ?>
 <? }else if($_GET['day']==5){ ?>
 <?php include("day7.php") ?>
<? }else if(!is_numeric($_GET['id']) || $_GET['id']<1){ ?>
invalid id (or page not found)
<? } ?>

</body>
</html>

header("Location: day7.php");
