So... Im trying to get this signature up

**Daiver** · 08-02-2005, 08:32 PM

I'm streaming audio and I want to get a signature up that displays my "currently playing" song. This is easily done with a PNG and a PHP script. However, I can't get that sig to work. I get the same error every time.

cannot be displayed, because it contains errors.

Here's the script:

Code:

<?php
// Ruff Dawg's 'Now Playing Sig w/ Background v. 1.5 May 7, 2004
// Special thanks to the originator, DJ Rampage

// This image you can call immediately from an html file in the image tag
// (i.e. <img src="black.php">)    easy huh?

    Header("Content-type: image/png");

    $im = imagecreatefrompng("banneraf.png");

    }
    if($success!=2){ //if connection
        fputs($fp,"GET /7.html HTTP/1.0\r\nUser-Agent: XML Getter (Mozilla Compatible)\r\n\r\n");

    }

    $px = (imagesx($im)-5*strlen($string1))/2;
    ImageString($im,$text_size,$x1,$y1,$string1,$text_color1);
    $px = (imagesx($im)-5*strlen($string2))/2;
    ImageString($im,$text_size,$x2,$y2,$string2,$text_color1);
    $px = (imagesx($im)-5*strlen($string3))/2;
    ImageString($im,$text_size,$x3,$y3,$string3,$text_color2);

    ImagePng($im);
    imagedestroy($im);
?>

I just can't get it going...

This line looks jacked up to me...

I'd try this...

PHP Code:


$fp = @fsockopen($host, $port, $errno, $errstr, 30);

Comment out the line that reads "Header("Content-type: image/png");" and then call the script from your browser. If you don't specify a header, PHP automatically assumes text/html and will output text. Most of the time when an image generating script doesn't work it is because PHP is throwing an error before it writes the image, corrupting it. Commenting out that line will let you see the error message(s) and help you find the problem.

Well, the weird thing is that this script, exactly as it is, worked just fine on another server. I'm guessing it has to do with permissions or something.

Anyway, I'll try those things and let you know.

**Daiver** · 08-03-2005, 09:55 AM

BTW, what does "commenting out the line" mean? I really don't know the first thing about PHP or Linux. Pretty much the average Windows fart over here...

**Awalsh** · 08-03-2005, 10:22 AM

PHP Code:


// Is a comment

# is a comment

/*

Multi Line Comment

*/



 $fp = @fsockopen($host, $port, $errno, $errstr, 30); 



//Notice the colour difference?

Comments basically tell the php parser to ignore that line or multiple lines if using the multi line comment.

**Daiver** · 08-03-2005, 10:56 AM

Hi,

Yeah, I kinda understood that commenting thing and know that some PHP files (especially the "template" kind downloaded off the Internet) have comments in them. The question is, how do I "comment out"? Should I erase the comments or that line that you suggested in post #3?

Thanks!

Nope, that didn't do it.

**jason** · 08-03-2005, 12:22 PM

"Commenting out" is a programmers term for changing actual code into comments so that the parser/compiler will ignore those instructions. To comment out the code as I suggested, just put two slashes in front of the line, as follows:

PHP Code:


// This image you can call immediately from an html file in the image tag

// (i.e. <img src="black.php">)    easy huh?



    //Header("Content-type: image/png");



/////////////////////////////////////////////////////////////////////////////////////////

That will lead PHP to belive that that line is just a comment and not an instruction, so it won't be executed. That line tells the browser to expect the data that follows to be a png image, so without it the browser will be expecting text. Once you make that change, call the script again and see if any errors appear. Once you sort out the errors and run the script without errors in it you'll see a lot of random characters on the screen. This is a text-rendering of the binary data that is your image. When you get that, remove the // from the header() line and run the script again. You should see your image.

Another thing to check, too (especially since you sid this script worked esewhere): make sure there are no spaces or blank lines after the last line of code, which should be (and is in your example) "?>." It is possible that extra data is being sent at the end of the image that the browser does not expect and that could be the root of your problem, even if the script runs correctly and doesn't generate any error messages. Also check that you uploaded the script in ASCII (or Text) mode and not binary.

Those two slashes "kinda" fixed the problem. Here's what I get now:

Fatal error: Call to undefined function: imagecreatefrompng() in /xxx/xxx/xxx/xxx/sig.php on line 19

Here's line 19:

$im = imagecreatefrompng("banneraf.png");

**jason** · 08-03-2005, 01:07 PM

It looks like the GD library on your server is out of date and doesn't support PNG images. I'd open a support ticket and ask to have it upgraded.

**Daiver** · 08-03-2005, 01:26 PM

Thanks, will do. I've recieved that answer elsewhere, but I didn't think it was the reason. Two people from different places can't be wrong.

Thanks!

**Daiver** · 08-03-2005, 03:00 PM

Good thing support works fast here! Got it working.

Thanks for the help!

**jason** · 08-03-2005, 03:03 PM

Cool. Glad you got it working. Support here is always great.
