custom block, type PHP

I wrote a php script that does a little "scraping" from another site and outputs some HTML, and I'm trying to use it in a custom block in XOOPS 2.0.5.

It doesn't seem to work.

I know the "fopen" works because some of the data is returned, but lots of other things go wrong, like my preg_match calls failing where they shouldn't, etc.

I ran the script in PHP command line mode on the hosting co's system and it works just fine.

Can anyone provide any hints on using PHP in custom blocks in general?

I'm wondering if XOOPS is changing some defaults that my script is depending on, and what they might be.

Is anyone using a custom block of type "PHP Script" for anything? I just spent a half hour looking through search results and it seems just about everybody finds them unusable.

What restrictions are there on the use of PHP in these blocks?

Well, here's one problem. Try this in a "PHP Script" block:

Quote:

function func_one ()
{
global $var_one;
print "I am func_one
\n";
print "var_one is: $var_one
\n";
}

$var_one = "Hello World";

print "I am main
\n";
print "var_one is: $var_one
\n";

func_one();


Why can't my function see $var_one ? Is there any way around this, other than passing all the globals in to the function?

Simple solution:

Quote:

global $var_one;

function func_one()
{
global $var_one;
print "I am func_one
\n";
print "var_one is: $var_one
\n";
}

$var_one = "Hello World";

print "I am main
\n";
print "var_one is: $var_one
\n";

func_one();


This does work, as expected. Problem solved.
