getimagesize() on a php file: fix or workaround?

ok i can use this perfectly for image files but if i wanna use itfortheavatar file lets say image.php then i seem to run into an errorofitgiving me 0's for height and width is their anyway to fix this?

* sabret00the using supermerge powers to supply extra info that may or may not help

Code:

Warning: getimagesize(image.php?u=10&dateline=1063118771):failed to open stream: Invalid argument in groups\groups.php on line172

is the error it spits out.

You don't show your actual code, but my guess is that you are not pointing getimagesize() at an actual file. You may have to try to use imagecreatefromstring() and then use imagesy() and imagesx() for your demensions.

heres the code

PHP Code:


		
			
            $grps_postsinfo['avatar']=iif($grps_postsinfo['hascustom'],"image.php?u=$grps_postsinfo[userid]&amp;dateline=$grps_postsinfo[avatardateline]","$grps_postsinfo[avatarpath]");
            usleep(1500);
            $avatarinfo = getimagesize($grps_postsinfo['avatar']);
            $avatarinfowidth = $avatarinfo[0]/2;
            $avatarinfoheight = $avatarinfo[1]/2;
            $grps_postsinfo['avatar']="<imgsrc=\"$vboptions[bburl]/$grps_postsinfo[avatar]\"width=\"$avatarinfowidth\"height=\"$avatarinfoheight\" alt=\"avatar\"/>";

i'll check into imagecreatefromstring() now.

Don't forget, it was posted at vb.com that iif() is being phased out and using it for data like that is highly inefficent.

:)

iif's are being phased out?

ok now just read it, could i just

PHP Code:


		
			
            $grps_postsinfo['avatar']=iif($grps_postsinfo['hascustom'],"image.php?u=$grps_postsinfo[userid]&amp;dateline=$grps_postsinfo[avatardateline]","$grps_postsinfo[avatarpath]");
            if ($grps_postinfo['hascustom'])
            {
                $grps_postinfo['avatar']= imagecratefromstring($postinfo['avatar'];
            }
            usleep(1500);
            $avatarinfo = getimagesize($grps_postsinfo['avatar']);
            $avatarinfowidth = $avatarinfo[0]/2;
            $avatarinfoheight = $avatarinfo[1]/2;
            $grps_postsinfo['avatar']="<imgsrc=\"$vboptions[bburl]/$grps_postsinfo[avatar]\"width=\"$avatarinfowidth\"height=\"$avatarinfoheight\"alt=\"avatar\"/>";

basically just making the adding the line to convert it to my script or will i have to use the imagesy() imagesx() functions?

just got back, it can't create the image from string it appears

Code:

Warning: imagecreatefromstring(): Passed data is not in 'WBMP' format in \groups\groups.php on line 180



Warning: imagecreatefromstring(): Couldn't create GD Image Stream out of Data in \groups\groups.php on line 180

PHP Code:


		
			
            if($grps_postsinfo['hascustom'])

            {

                usleep(1500);

                $grps_postsinfo['avatar'] = "image.php?u=$grps_postsinfo[userid]&amp;dateline=$grps_postsinfo[avatardateline]";

                $grps_postinfo['avatar']= imagecreatefromstring($grps_postinfo['avatar']);

                $avatarinfo = getimagesize($grps_postsinfo['avatar']);

                $avatarinfowidth = $avatarinfo[0]/2;

                $avatarinfoheight = $avatarinfo[1]/2;

                $grps_postsinfo['avatar'] = "image.php?u=$grps_postsinfo[userid]&amp;dateline=$grps_postsinfo[avatardateline]";

                $grps_postsinfo['avatar'] = "<img src=\"$vboptions[bburl]/$grps_postsinfo[avatar]\" alt=\"avatar\" />";

            }

            else

            {

                usleep(1500);

                $grps_postsinfo['avatar'] = "$grps_postsinfo[avatarpath]";

                $avatarinfo = getimagesize($grps_postsinfo['avatar']);

                $avatarinfowidth = $avatarinfo[0]/2;

                $avatarinfoheight = $avatarinfo[1]/2;

                $grps_postsinfo['avatar'] = "<img src=\"$vboptions[bburl]/$grps_postsinfo[avatar]\" width=\"$avatarinfowidth\" height=\"$avatarinfoheight\" alt=\"avatar\" />";

            }

is the code in charge, i already miss the precious iff's :(

getimagesize expects a file from the file system with a valid path and name.

imagecreatefromstring gives you a GD handle to use imagesy() imagesx().

This page has all the info ya need. http://us4.php.net/manual/en/ref.image.php

thanks, will that help me to make the data into a string too?

I'm not sure what you mean, but if you mean a new pic from that string, look at imagejpg() imagepng() and imagegif().

yup that's what i meant cos it's saying

Warning: imagecreatefromstring(): Passed data is not in 'WBMP' format in \groups\groups.php on line 179

my initial plan was to use file_get_contents() and go from there but that never worked :-S
