varibale problem

[JamesThePanda]

ok I have this function called

the_ID();

 

I want to set it as a variable

So i did the following

$id = the_id();

 

And to test it I wanted to echo $id

 

 

so this was the simple piece of code I wrote

<?php $id = the_ID();
                    echo $id;
	?>

 

But nothing is being echoed what am  doing wrong ?

 

Thanks

Echoing a FALSE value generally does not echo anything. You can try var_dump($id); to determine exactly what is in the variable.

Well we'd need to see the code for your function to correct it, but I'd guess that it doesn't return any values.

 

Example:

 

<?php

function the_ID()
{
return 2;
}

$id = the_ID();
echo $id; // 2 is echo'd

?>

wellits ment to echo a page number If i do

 

<?php echo the_ID(); ?>

 

That echos the page number

 

but I want to take the page number and do thing with it so I want to be able to have it as a variable.

If you can use echo the_ID(); and it works, then you can assign that to a variable and use that variable. If that variable then does not have the expected value in it, your code has done something to that variable between the point where it was assigned a value and where you are using it.

 

You will need to post your actual code if you want help with why it is not working.

in your function change 'echo' to 'return'
