[PHP] evaluating php expressions using Sablotron
Hi,
I am using php >4.1, with Sablotron.
I have both an xml and xsl file, and use sablotron to output html. But the
php expressions inside these files are not evaluated (i.e. left out in the
html-file)
How can they be evaluated for sure?
(most examples use sablotron with php4.0 and are therefore not of much
use...)
Here is what I have:
index.php:
PHP:
'PIHandler'));
// process the two files to get the desired output
$result = xslt_process($xslthandler, $xmlfilename, $xslfilename);
if ($result) {
echo $result;
}
else {
print "Sorry, \$xmlfile could not be transformed by \$xslfile into";
print " the \$result variable. Reason: " . xslt_error($xslthandler);
print ". Error code: " . xslt_errno($xslthandler);
}
// free the resources occupied by the xslthandler
xslt_free($xslthandler);
// processing instruction handler
function PIHandler($parser, $data, $target) {
echo $data; // not working...
switch (strtolower($target)) {
case "php":
eval("?>$data"); // not working...
echo Date("Y"); // blah...
break;
}
}
?>
processing instruction handler isn't working...
$target contains 'php' when found an pi. But the $data does contains 'blah
blah' (no data). Further it does process the code inside the pihandler, but
I still can't pass php code to it.
(in php4.0 the arguments were like in: function PIHandler($parser, $target,
$data), I changed the order, so that $target contains 'php' when an pi is
encountered)
The xml file contains sometimes pieces of php code like:
PHP:
--
The xsl-file contains a piece like:
PHP:
hello
echo "hello";
But nothing seems to work...
--
It's really frustrating: I mean, I just want to evaluate some php code
inside the xml and xsl files. What's the big deal? Why should this be so
complicated? Please help.

done, you can pass the contents of the output buffer to an XSLT processer

Can someone show me how using an example?
Thanks,

Those pass any string except where there occurs a sequence of three
non-digit chars. So "123AB", "AB", "A", "1 2 3", etc. would all slip
through as apparently valid area codes. Instead, how about:
//<-if anything but a sequence of exactly three digits from beginning to
end...
if (!eregi("^[[:digit:]]{3}$",$co_area))
{
//throw an error message
echo "Sorry, only a three digit area code is permitted!";
}

or

if you use the POSIX regex fields.

First mistake when using character classes in the pattern is that the
hyphen must be at the end if it is to be included. Otherwise the hyphen
is seen to be part of the range (0-9 or A-Z):
so, ^[0-9a-zA-Z._-]{3,12}
instead of what you have. You also should not need the trailing $.
As in the first example, don't use the 'double negative' approach.
use:
if (eregi("^[^0-9a-zA-z._-]{3,12}",$nickname)) {
echo "only alphanumeric buddy!";
}
I didn't test this but it should be closer to success.

I don't know anything about ereg and regex, so if there's an error in that
part I won't be able to help with that, but I can tell you that ($something
!= !$something_else) is a double negative, it's like saying "I can't not
program in PHP." You might as well say ($something == $something_else), save
the obfuscation factor.
Since you want to do something when ereg is false, you should say:
if (!ereg(...)) {
Do a bunch of stuff;
}

[PHP] expressions
hi,
im trying to fix this couple of hours but i couldnt find the mistake...
can somebody look at it...
first i want to check the $co_area for 3 digital ... it must contain 3
digital
if ($co_area != !ereg("([0-9]{3})",$co_area))
{ echo " * Area code must be 3 digital"; }
second...
nickname check works but the first letter could be any number or any
letters
with this code it accept only letters as first character... i just want
any letter or numbers or - _ symboles from 3 to 12 characters...
if ($nickname != !eregi("^[-\._\.0-9a-zA-Z]{3,12}$",$nickname))
{
$error ="Nickname must be Alphanumeric[ a-z 0-9; - _ ; 3 - 12
characters ]";
$flak=1;
}
i hope someone can help me to fix this...
thanx
