script on half runs when called from php

[matthewst]

I can run the following script from the web it won't convert but it does display "hello world".

test1.pl

#!/usr/bin/perl
exec "convert image.pdf image.jpg";
print "hello world";

If I'm on the server I can type "perl test1.pl" and it will convert and display hello world.

You should put in full path's to everything. Full path to the convert command, full path to your files. If you don't know where the files are you can use whereis on *nix.

the exec command is failing matthew - it's not actually running "convert" - if it were, even if convert were giving you an error msg, you wouldn't see hello world. The exec command effectively stops the script right there if it works - commands after a line with exec on it shouldn't execute.

When working on any project the value of other people is exactly that - they are other people, with views that don't necessarily match yours. This mismatch, between their views and the view you've been contentedly assuming is right, is where that value lies.

Change to using back ticks instead of exec.
@output = `/path/to/convert /path/to/file1 /path/to/file2`;
print "@output\n";

When I run your script through php it just displays "hello world" (which i placed after "print "@output\n"). If I run it in terminal i get the following error:

dyld: Library not loaded: /usr/X11R6/lib/libdpstk.1.dylib
Referenced from: /usr/local/bin/convert
Reason: no suitable image found. Did find:
/usr/X11R6/lib/libdpstk.1.dylib: mach-o, but wrong architecture

Thats the same error I get when calling convert in php which is why I'm trying to make it work with perl. I found and place a copy of libdpstk.1.dylib in the correct location but it still doesn't want to work.

It works from the command line, it works in a perl script. It won't work when called from php.

Probably a permissions/path type issue. When you run it from the web site then it is being ran as the user that runs the httpd daemon (ps -ef | grep httpd) normally

http://www or

something like that.

I dont have a

http://www or

a httpd user. How do I fix that?
Just add one in "Workgroup Manager"?

 

[travs69]

No.. you need to see what user your web site is being run as.. are you on windows or unix?

xserve 10.4

unix

do a
ps -ef | grep httpd

and it will show you what user httpd is running as. You should test your scripts as this user.

I get an illegal option with the -ef combo. If I just run the -e I get "11474 p1 S+ 0:00.00 grep httpd TERM_PROGRAM=Apple_Terminal TERM=xterm-col
