passing variable in url

lovinlazio9

hi guys...here's my code, i've been looking all over the net and just haven't found anything that can make this work, i'm sure i'm doing it wrong or placing my code in the wrong place but any help will do thanks...

basically when you are at one page and want to make a comment for that...i want to pass the variable through the URL..when you click the URL, it takes you to a submit comment form where i will need the variable in the URL... let me know thanks...

heres the main page that has the link in it:

<?
$poi_id='1';
?>



<p style="max-width:584px;"><b><a href="http://www.myurl/review.php?poi_id=$poi_id"><font face="Verdana" size="2" color="#BABAA0">WRITE
A REVIEW</font></a></b></p>

then, on the actual comment page i used $_GET but it hink i'm doing it wrong...

<?
session_start();
if(!session_is_registered(Email)){
header("location:login.php");
}
?> 

<?

include( "header.php" );
$_GET[poi_id];
?>

anything will help thanks!

hmm i think you need:

Part A:

<?php

echo "<a href='http://www.myurl/review.php?poi_id='.$poi_id."'>";

WRITE A REVIEW</a>

Part B:

i think you need to store the value of $GET[poi_id] in some variable first. eg $podID = $GET[poi_id];

not very sure though. good luck!

In the first part you need to make sure that the PHP variable is passed on and not the value "$poi_id". bongbong have suggested one solution that is almost working (just to take out one " sign), and here is another.

<?
$poi_id='1';
?>

<p style="max-width:584px;"><b><a href="http://www.myurl/review.php?poi_id=<?php echo $poi_id ?>"><font face="Verdana" size="2" color="#BABAA0">WRITE
A REVIEW</font></a></b></p>

In the second part you need to do two things. First you need to store the value in a variable (or use it right away). But you still need to do something with it, just to add it to a variable is not enough for you to see that it is correct. Second you need to add ' signs when getting the variable.

<?
session_start();
if(!session_is_registered(Email)){
header("location:login.php");
}
?> 

<?

include( "header.php" );
$id = $_GET['poi_id'];       // This row is changed, not any other
?>
