[SOLVED] URL Get: Pass a variable name to another variable in a URL?

[foochuck]

I would like to pass $var1 to $masterVar so that both variables are exact copies - however I want to do this though a URL...(using the get method)...

 

$var1 = "My text goes here";

 

http://www.thewebsite.com?masterVar=var1

 

However when I "get" $masterVar it comes out reading a string "var1" - I want it to read "My text goes here"

 

Please help!

 

FOO

http://www.thewebsite.com?masterVar=$var1

[foochuck]

$masterVar = $_GET["masterVar"];

 

or

 

$masterVar = $_GET[masterVar];

 

http://www.thewebsite.com?masterVar=$var1

[trq]

$masterVar = $_GET["masterVar"];

[foochuck]

The output of $masterVar still reads $var1 instead of My text goes here

 

$masterVar = $_GET["masterVar"];

How do you create the link? Please show us your code.

Page 1:

 

$var1 = "This is my text";

 

<a href="http://www.thewebsite.com/project.php?masterVar=$var1">Link</a>

 

Project.php Page:

 

$masterVar = $_GET["masterVar"];

 

echo "$masterVar"; // This reads $var1

[craygo]

use this

 

$var1 = "My text here";
$masterVar = $$_GET['masterVar'];
echo $masterVar;

 

And the url will be

http://www.thewebsite.com?masterVar=var1

show your actual code (in code tags).  It looks to me like you're using single quotes around it so it's interpreting $var1 literally. You need to either have it in double quotes or not in quotes at all:

 

echo "http://www.thewebsite.com/project.php?masterVar=$var1";

// or

echo "http://www.thewebsite.com/project.php?masterVar=" . $var1;

Are you echoing the link via PHP or is it hard coded HTML?

I am using double quotes and I am echoing the link via PHP.

 

I tried craygo's solution but nothing even shows up when I echo the $masterVar with that option.

[foochuck]

I tried this suggestion but it didn't work. I didn't receive any errors - and with this method not even $var1 showed up.

 

use this

 

$var1 = "My text here";
$masterVar = $$_GET['masterVar'];
echo $masterVar;

 

And the url will be

http://www.thewebsite.com?masterVar=var1

show your actual code from source and target scripts (use code tags) seriously I think we're making a way bigger issue out of this than it really is.  I mean, the only way it would literally echo out "$var" instead of the value of $var is if you're a) trying to echo out the link (with the variable) in single quotes, or b) your link is just plain text outside of php tags (regular html).  There's really no other reason, except for that your script isn't being parsed at all, which it obviously is, as something is being received and echoed out.

You use header for redirecting OR a click URL method to pass variable to next page.

Show your complete code.

[foochuck]

I'm using a basic click URL method to pass the variable to the next page...

 

<a href="http://www.thewebsite.com/projects.php?masterVar=var1">My Link</a>

$var1 = "This is my text";

echo "$masterVar"; // This reads $var1 - I'd like it to read This is my text

 

Okay man, I don't mean to sound rude, but you got to focus here.... You keep showing separate little chunks of code.  That does nothing for us. You need to copy/paste your entire code.  You said earlier you are echoing your link, with quotes, without quotes, etc.. but you just keep pasting a link out of context.

 

Not counting security issues, this is what your code should look like, no more, no less:

 

page1.php

<?php
$var1 = "This is my text";

echo "<a href = 'http://www.thewebsite.com/projects.php?masterVar=$var1'>my link</a>";
?>

 

projects.php

<?php
$masterVar = $_GET['masterVar'];

echo $masterVar; // output: This is my text
?>

Crayon Violent is right.

Follow his code.

Thanks for everyone's help with this topic.

 

The problem was that I wasn't using the a tag / url in an echo function.

umm...do you mean to say that you forgot the

?

 

There's no possible way that that would cause your variable to be passed literally.  The only three ways it could be passed literally is

 

a) you had single quotes around it

b) it was not wrapped in <?php ... ?> tags as an echo. 

c) your server doesn't recognize and therefor isn't parsing it (which we ruled out)

 

Those are the ONLY three ways.  I'm just trying to make this very clear for you, because I don't want you walking away thinking that php code breaks like that when not closing an html tag.  It could make what's echoed out look funny markup-wise, but it cannot in any way determine literal vs. figurative interpretation.

Understood. Thanks Crayon.
