Passing variables into URL

[adrian_]

Hi,

I'm trying to pass a variable into a URL and apparently I'm doing it wrong

 

this code is OK

$id = $3;
echo '<a href="newPage.php?id=3"></a>

If I use

$id = $_GET['id'];
echo $id;

on the newPage.php, I echo 3

whereas, if I do

$id = $3;
echo '<a href="newPage.php?id="'.$id.'"></a>

when echo out on the newPage.php it prints out nothing

also, in current url look like this:

www.site.com/newPage.php?id=

 

What am I doing wrong? 

 

Many thanks

$id = $3;

 

$3 is not a valid variable name, nor is it a valid literal.

 

Try

$id=3;

My bad for

$3

I tried the way you suggested, but still no luck.

[objnoob]

echo '<a href="newPage.php?id="'.$id.'"></a>

 

That is wrong too!

 

Try (how I would do)

echo "<a href='newPage.php?id={$id}'></a>";

 

or (how you were trying, but fixed...)

 

echo '<a href="newPage.php?id='.$id.'"></a>';

<?php 

$id = 3;

echo '<a href="page.php?id='.$id.'">link</a>';

?>

 

works fine for me.

Hi guys

 

Apparently that was my problem, I had a double quote immediately after the equal sign. Got rid of it, everything works

 

Thank you
