Why printing config array gives empty Array? - php

$tpl = new Smarty();
$tpl->configLoad('compose.conf');
$config = $tpl->getConfigVars();
print_r($config);
it returns
Array()
What is it, I am doing wrong?
compose.conf
[jquery]
jquery = lib/jquery/jquery.js
[jquery_validate]
css=res/css/jquery.validate.css
js=lib/jquery/jquery.validate.js
X=jquery
[bootstrap_css]
main = lib/bootstrap/css/bootstrap.min.css
theme = lib/ootstrap-theme.min.css
[bootstrap_js]
js = lib/bootstrap/js/bootstrap.min.js
X=jquery
[bootstrap]
X=bootstrap_css,bootstrap_js
[utils]
utils=lib/utils/utils.js
odo=lib/utils/utils.odo.js
require=libutils/utils.require.js
template=lib/utils/utils.template.js
X=jquery

In your smarty plugins directory
smarty_internal_config.php
search for statment
if (!empty($sections)) {
now replace this statement with
if($sections=='*'){
foreach ($_config_vars['sections'] as $key=>$value) {
if (isset($value['vars'])) {
$scope_ptr->config_vars[$key] = $value['vars'];
}
}
} else if (!empty($sections)) {
and while loading file use it like this
$tpl = new Smarty();
$tpl->configLoad('compose.conf','*');
$config = $tpl->getConfigVars();
print_r($config);
Thats it:)

According to the manual of parse_ini_file:
Note: There are reserved words which must not be used as keys for ini files. These include: null, yes, no, true, false, >>> on <<<, off, none. Values null, off, no and false result in "". Values on, yes and true result in "1". Characters ?{}|&~![()^" must not be used anywhere in the key and have a special meaning in the value.
If we try to execute parse_ini_file (or parse_ini_string) on your file we get the following error:
Warning: syntax error, unexpected BOOL_TRUE in Unknown on line 7
in /tmp/execpad-e67cf6f095ae/source-e67cf6f095ae on line 32
Hence Smarty is getting an error (I'm assuming that it uses one of these functions internally) when trying to parse your INI file because you use a reserved word. The solution is to simply rename ON to something else.
Update:
Smarty doesn't use these functions, but its parser replicates it. Line #313 of smarty_internal_configfilelexer.php refers to "on":
if (!$this->smarty->config_booleanize || !in_array(strtolower($this->value), Array("true", "false", "on", "off", "yes", "no")) ) {

How do I use the output from a php file in a TemplaVoila FCE?

I am trying to use the output from a php file in a TemplaVoila FCE.
According to the articles, etc, I have found on the subject, I seem to be doing it right. But it does not work.
I have reduced my implementation to a very simple test, and I hope that someone here can tell me what I am doing wrong.
The php code is in fileadmin/php/test.php
The file contains this code:
<?php
function getBeechgroveTest($content, $conf)
{
return 'B';
}
//echo getBeechgroveTest(0,0);
?>
In the main template (template module - not TemplaVoila) I have added this line:
includeLibs.beechgroveTest = fileadmin/php/test.php
I have tried to put it at the root level and inside a PAGE object. Both gave the same result.
If I uncomment the 'echo' line I get a 'B' at the top of my HTML page, so the php must be read at some point.
My FCE has one field of type 'None (TypoScript only)' and contains this code:
10 = TEXT
10 {
value = A
}
20 = USER
20 {
userFunc = getBeechgroveTest
}
30 = TEXT
30 {
value = C
}
I was expecting the FCE to output 'ABC', but I only get 'AC'.
What am I doing wrong?
I use TYPO3 version 4.5.30 and TemplVoila 1.8.0
It must by problem in cache, try use USER_INT instead USER. If you create this object as USER_INT, it will be rendered non-cached, outside the main page-rendering.
20 = USER_INT
20 {
userFunc = getBeechgroveTest
}

Access a PHP array with Perl

I am primarily a PHP developer and have limited experience with Perl.
I was tasked with writing a queue script in Perl which checks against a database, and that is all working out great.
The problem I have is that in the Perl script I need to include a database hostname and password.
Right now I have them hard coded, which works fine, but my PHP application uses a global PHP array which holds the database hostname and password.I'd like to be able to use this PHP array in my Perl script.
Here is my PHP array
<?php
return array(
'database' => array(
'master' => array(
'hostname' => 'fd35:4776:6804:2:a::1',
'password' => 'password'
),
'slave' => array(
'hostname' => 'fd35:4776:6804:2:2::2',
'password' => 'password',
'profile' => true
)
)
);
I've tried searching with Google and have read many random posts on line, but I have yet been able to come up with a solution.
Does anyone have any ideas which I could try? If I'm missing any additional input, let me know and I can provide it.
Edit
Hopefully I worded this properly. How would I go about including this PHP array file so that I can manipulate it with Perl?
Alternative solutions are welcome too!
You've discovered one of the many reasons why code makes for bad config files. You should move the information to an actual config file, and access that file from both that .php file and from Perl.
JSON would make a decent file format here.
{
"database": {
"master": {
"hostname": "fd35:4776:6804:2:a::1",
"password": "password"
},
"slave": {
"hostname": "fd35:4776:6804:2:2::2",
"password": "password",
"profile": true
}
}
}
The Perl code would be
use JSON::XS qw( decode_json );
open (my $fh, '<:raw', $config_path)
or die("Can't open config file $config_path: $!\n");
my $file; { local $/; $file = <$fh>; }
my $config = decode_json($file);
On the PHP side, just replace the contents of the file you showed in your post with code to read the config file. I don't know PHP, but it should be quite simple. A quick search shows it might be
return json_decode(file_get_contents($config_path));
It would be simple to provide a short PHP program that dumps the array to a file in JSON format. That file can then be read from Perl using the JSON module.
This is all that is necessary.
<?php
$array = include 'array.php';
$fh = fopen('array.json', 'w');
fwrite($fh, json_encode($array));
fclose($fh);
?>
The resultant JSON file can then be read in a Perl program, like so:
use strict;
use warnings;
use JSON 'from_json';
my $data = do {
open my $fh, '<', 'array.json' or die $!;
local $/;
from_json(<$fh>);
};
use Data::Dump;
dd $data;
output
{
database => {
master => { hostname => "fd35:4776:6804:2:a::1", password => "password" },
slave => {
hostname => "fd35:4776:6804:2:2::2",
password => "password",
profile => bless(do{\(my $o = 1)}, "JSON::XS::Boolean"),
},
},
}
There is PHP::Include, which uses a source filter to let you have PHP blocks in your Perl code to declare variables. It also has a read_file() function that applies such a filter to a single PHP file.
But it seems to expect that your PHP has assignments (e.g. $config = array('database' => array(...) and changes those to Perl variable declarations.
In a few minutes of playing with it, I couldn't get it to do anything useful with your PHP code that uses return.
If you want a more "native Perl" solution, you can pretty much* just search and replace all your "array(" and their matching ")" to "{" and "}". That'll give you a perl datastructure called a "hash of hashes" (note: Unlike PHP, Perl refers to arrays with integer indicies as arrays (and uses the # sigil to denote variables containing them), but refers to array-like things with string indicies as "hashes" (and uses the % sigil to denote variables containing them)). The Perl keywords/concepts you probably want to read up on are:
Perl Data Structures: http://perldoc.perl.org/perldsc.html
and specifically the Hash Of Hashes section: http://perldoc.perl.org/perldsc.html#HASHES-OF-HASHES
and if you dont understand what $hashref = \%hash and %hash{key} and $hashref->{key} mean in Perl, you'd want to read http://perldoc.perl.org/perlref.html
Example code (note how similar the getConfig subroutine is to your PHP code):
#!/usr/bin/perl
use strict;
use warnings;
my $config=getConfig();
print "Database master host = " . $config->{database}{master}{hostname};
print "\n";
print "Database master password = " . $config->{database}{master}{password};
print "\n";
print "Database slave profile = " . $config->{database}{slave}{profile};
print "\n";
sub getConfig{
return {
'database' => {
'master' => {
'hostname' => 'fd35:4776:6804:2:a::1',
'password' => 'password'
},
'slave' => {
'hostname' => 'fd35:4776:6804:2:2::2',
'password' => 'password',
'profile' => 'true'
}
}
};
}
I said "pretty much", because your sample data used the bare word 'true' for the slave->profile value - that's a syntax error in Perl - you can change it to a bare 1, or quote the value as "true" to make it work. In Perl, the digit zero, the string "0" or the empty/nul string "" all evaluate to "false" in a boolean context, anything else evaluates to "true". Take care if you choose to automate PHP to Perl translation, there may be other PHP-isms which could catch you out like that.
So much good information here and it helped me out quite a bit to come up with a working solution.
Here is the perl script I've got working:
#!/usr/bin/perl
use PHP::Include;
include_php_vars( 'config.local.php' );
my $test = \%config;
print $test->{'database'}->{'master'}->{'hostname'};
I also took the PHP array and changed it so that it no longer return array() but $config = array() and then return $config;
This did the trick for me. Thank you!

Creating default object from empty value in php 5.4

i have some code like this:
function getAuthorizedPFComponents($pfState)
{
$authorizedPFComponents = new \stdClass();
$compTypeMap=array('platform'=>'pfAuthorizations','mainSite'=>'mainSiteAuthorizations','microSites'=>'microSiteAuthorizations','apps'=>'appAuthorizations');
foreach($compTypeMap as $compType=>$tagName)
{
$authorizationsNode=$this->pfAuthXMLDOM->getElementsByTagName($tagName)->item(0);
foreach($authorizationsNode->getElementsByTagName('authorizations') as $pfComponentAuthElem)
{
foreach($pfComponentAuthElem->getElementsByTagName('allow') as $allow)
{
switch($allow->getAttribute('orgCode'))
{
case 'K_ALL':
{
$authorizedPFComponents->$compType->{$pfComponentAuthElem->getAttribute('pfComponentCode')}->storeCode=$allow->getAttribute('storeCode');
}
}
It shows a warning:
Warning: Creating default object from empty value
The warning is traced back to the code under case K_ALL:
This was too long for a mere comment, so I'll remove it when it has outlived its usefulness.
First thing you should do is make the code simpler; there's a lot of stuff going on in that one statement:
$compCode = $pfComponentAuthElem->getAttribute('pfComponentCode');
$storeCode = $allow->getAttribute('storeCode');
And add debug code:
var_dump($authorizedPFComponents->$compType);
var_dump($authorizedPFComponents->$compType->$compCode);
$authorizedPFComponents->$compType->$compCode->storeCode = $storeCode;
Consider this code:
$x->y = 'test';
If $x is not defined, it will issue a warning:
Warning: Creating default object from empty value in xxx
The same goes for your chain of references:
$authorizedPFComponents->$compType->$compCode->storeCode
If any of those paths is empty, the next ->yyy will cause that warning.

In PHP, how can I detect that input vars were truncated due to max_input_vars being exceeded?

I know that an E_WARNING is generated by PHP
PHP Warning: Unknown: Input variables exceeded 1000
But how can I detect this in my script?
A "close enough" method would be to check if( count($_POST, COUNT_RECURSIVE) == ini_get("max_input_vars"))
This will cause a false positive if the number of POST vars happens to be exactly on the limit, but considering the default limit is 1000 it's unlikely to ever be a concern.
count($_POST, COUNT_RECURSIVE) is not accurate because it counts all nodes in the array tree whereas input_vars are only the terminal nodes. For example, $_POST['a']['b'] = 'c' has 1 input_var but using COUNT_RECURSIVE will return 3.
php://input cannot be used with enctype="multipart/form-data". http://php.net/manual/en/wrappers.php.php
Since this issue only arises with PHP >= 5.3.9, we can use anonymous functions. The following recursively counts the terminals in an array.
function count_terminals($a) {
return is_array($a)
? array_reduce($a, function($carry, $item) {return $carry + count_terminals($item);}, 0)
: 1;
}
What works for me is this. Firstly, I put this at the top of my script/handler/front controller. This is where the error will be saved (or $e0 will be null, which is OK).
$e0 = error_get_last();
Then I run a bunch of other processing, bootstrapping my application, registering plugins, establishing sessions, checking database state - lots of things - that I can accomplish regardless of exceeding this condition.. Then I check this $e0 state. If it's not null, we have an error so I bail out (assume that App is a big class with lots of your magic in it)
if (null != $e0) {
ob_end_clean(); // Purge the outputted Warning
App::bail($e0); // Spew the warning in a friendly way
}
Tweak and tune error handlers for your own state.
Registering an error handler won't catch this condition because it exists before your error handler is registered.
Checking input var count to equal the maximum is not reliable.
The above $e0 will be an array, with type => 8, and line => 0; the message will explicitly mention input_vars so you could regex match to create a very narrow condition and ensure positive identification of the specific case.
Also note, according to the PHP specs this is a Warning not an Error.
function checkMaxInputVars()
{
$max_input_vars = ini_get('max_input_vars');
# Value of the configuration option as a string, or an empty string for null values, or FALSE if the configuration option doesn't exist
if($max_input_vars == FALSE)
return FALSE;
$php_input = substr_count(file_get_contents('php://input'), '&');
$post = count($_POST, COUNT_RECURSIVE);
echo $php_input, $post, $max_input_vars;
return $php_input > $post;
}
echo checkMaxInputVars() ? 'POST has been truncated.': 'POST is not truncated.';
Call error_get_last() as soon as possible in your script (before you have a chance to cause errors, as they will obscure this one.) In my testing, the max_input_vars warning will be there if applicable.
Here is my test script with max_input_vars set to 100:
<?php
if (($error = error_get_last()) !== null) {
echo 'got error:';
var_dump($error);
return;
}
unset($error);
if (isset($_POST['0'])) {
echo 'Got ',count($_POST),' vars';
return;
}
?>
<form method="post">
<?php
for ($i = 0; $i < 200; $i++) {
echo '<input name="',$i,'" value="foo" type="hidden">';
}
?>
<input type="submit">
</form>
Output when var limit is hit:
got error:
array
'type' => int 2
'message' => string 'Unknown: Input variables exceeded 100. To increase the limit change max_input_vars in php.ini.' (length=94)
'file' => string 'Unknown' (length=7)
'line' => int 0
Tested on Ubuntu with PHP 5.3.10 and Apache 2.2.22.
I would be hesitant to check explicitly for this error string, for stability (they could change it) and general PHP good practice. I prefer to turn all PHP errors into exceptions, like this (separate subclasses may be overkill, but I like this example because it allows # error suppression.) It would be a little different coming from error_get_last() but should be pretty easy to adapt.
I don't know if there are other pre-execution errors that could get caught by this method.
What about something like that:
$num_vars = count( explode( '###', http_build_query($array, '', '###') ) );
You can repeat it both for $_POST, $_GET, $_COOKIE, whatever.
Still cant be considered 100% accurate, but I guess it get pretty close to it.

PHP Error on Code it should not be running

First let me say sorry for the amount of code I'm posting below I'm going to try and keep it as short as possible but this is built on top of my MVC (lightweight-mvc)
Ok So my Problem is that for some reason php is throwing a fatal error on code that should not be being used in my current code,
So how this works I have my MVC witch used the first 2 parts of the url to know what its loading, the problem is I'm building a Moulder CMS into my MVC so it's boot strapping twice,
So here is my Problem,
http://{domain}/admin/control/addon/uploader/method/uploadCheck/
I'm using the above now let me explain a little into that the /admin/control are for the main MVC System it auto-loads the Admin controller then fires the controlAction method from the controller much the same as most MVC's,
The next part are URL paramters that build an array the same as GET or POST would
array('addon'=>'uploader', 'method'=>'uploadCheck')
So from that my control action will auto load as is the code below
public function controlAction(){
global $_URL;
if(cleanData::URL("addon")){
$addonName = "addon_".cleanData::URL("addon");
$methodName = (cleanData::URL("method"))? cleanData::URL("method")."Action" : "indexAction";
echo $methodName;
$addon = new $addonName();
$addon->$methodName();
return;
}else{
$this->loadView("CMS/controll");
}
}
cleanData::URL is an abstract method that just returns the value of the key provided though addSlashes()
So as you can see from the code below it will then use the autoloader to load the module(AKA addon)
Just so you can follow the auto loader works in a simpler version of the Zend Frame work autoloader _ so you have class name addon_admin that would be inside file admin.php that is in the folder addon so the autoloader will load addon/admin.php
So As above with my URL and controlAction it's loading addon/uploader.php and as such this is the contents
<?php
class addon_uploader extends Addons{
public function uploadCheckAction(){
echo 0;
}
public function uploaderAction(){
if (!empty($_FILES)) {
$tmpFile = $_FILES['Filedata']["tmp_name"];
$newLock = "../uploads/".end(explode('/', $tmpFile).$_FILES['Filedata']['name']);
move_uploaded_file($tmpFileName, $newLock);
$POSTback = array(
'name' => $_FILES['Filedata']['name'],
'type' => $_FILES['Filedata']['type'],
'tmp_name' => $newLock,
'error' => $_FILES['Filedata']['error'],
'size' => $_FILES['Filedata']['size']
);
echo json_enocde($POSTback);
}
}
}
?>
But as you can see from my URL its using the uploadCheckAction method witch for debugging i have set so it always says false (AKA 0),
But i seem to get this error:
Fatal error: Only variables can be passed by reference in C:\xampp\htdocs\FallenFate\addon\uploader.php on line 11
But line 11 is $newLock = "../uploads/".end(explode('/', $tmpFile).$_FILES['Filedata']['name']); witch should not be being used could any one provide any help into why this would occur and how i could fix it
end() PHP Manual needs an expression of a single variable (more precisely an array), but not a function return value or any other type of expression.
I think that's basically the cause of your error, more specifically with your code:
$newLock = "../uploads/".end(explode('/', $tmpFile).$_FILES['Filedata']['name']);
you're even driving this far beyond any level of treatment PHP can cope with:
you concatenate an array with a string (which results in a string).
you run end() on that string - not on a variable, not even an array.
I have no clue what you try to do with the code, but I can try:
$filename = $_FILES['Filedata']['name'];
$parts = explode('/', $tmpFile);
$last = end($parts);
$newLock = "../uploads/". $last . $filename;
Or probably even only this:
$filename = $_FILES['Filedata']['name'];
$newLock = "../uploads/". $filename;
