PHP echo command ...

Hi,

I just want to "echo" (display / print) $vars to ensure my code is ok but the echo "xyz..."; doesn't print nothing wherever I script it.

So the question is : how to print any message in the window.
I do not mention any special procedure or function because I guess the answer is generic for all the ckfinder .

Thanks in advance

Re: PHP echo command ...

For ex. if you want to display a var called "id" put:

<?php echo $_GET[id] ?>

to do display the var.

and remember var's are case sensitive,

<?php echo $_GET[ID] ?>

it's not the same thing as:

<?php echo $_GET[id] ?>

Hi Robertor,

I agree with your answer ... but it doesnt answer what I asked, may be I was not enough precise.

For example, and as mentionned in a post, I want to modify the /commandhandler/fileupload.php to fit my needs. To ensure that what I modify is OK, I want to 'echo' somes $vars. And when I place an echo command in this script I can't see the echoed $vars on the screen ...
So, what do I have to do to see on the browset the echoed $vars, or where is it echoed ?

thanks

Take a look at the sendResponse() method.

Add somewhere inside of that function:

print_r($yourVariable);
die();

and use Fiddler + IE to check the response (click on a Session Inspector tab).

Or perhaps an easier way, use your error log file to trace variable (check your error log after uploading file):

$myVariable = "some string";
error_log("CKFinder_Log [".date("Y:m:d H:i:s")."]: " . $myVariable);

or another way: save contents of your variable to a custom file (for example using file_put_contents()):

   ob_start();
print_r($myVariable);
file_put_contents("/path/to/dump.txt", ob_get_clean(), LOCK_EX);

We'll be working on making the debugging process easier in the near future.
