How do you print all variables available in the context of a Smarty template? Something like the Django debug trace that lists everything being passed.
Thanks
Use {debug} From the manual:
{debug} dumps the debug console to the
page. This works regardless of the
debug settings in the php script.
Since this gets executed at runtime,
this is only able to show the assigned
variables; not the templates that are
in use. However, you can see all the
currently available variables within
the scope of a template.
$debugging = true must be enabled in your settings or class, and site popups must be unblocked to see the window
var_dump($Smarty->_tpl_vars);
From the Smarty code :)
Updated answer for Smarty 3: getTemplateVars
// If no parameter is given, an array of all assigned variables are returned.
$all_tpl_vars = $smarty->getTemplateVars();
$all_tpl_vars = $smarty->getTemplateVars();
var_dump($all_tpl_vars);
//before pushing to the template
exit;

I'm trying to modify the user's address right after registration.
When you create a new user, The address needs to be modified and a trailing string needs to be added, such as this : ####.
I've created an addon, added the path /controllers/frontend/profiles.post.php,
I've attached to the $mode == 'add' , That's where I'm stuck.
How can I know which variables are available to me, It seems there's no way to debug, var_dump or echo. nothing seems to work.
The file is executing because if I type some broken syntax the server returns 500 internal error,
So my main question :
How can you debug at all any CS-cart addon?
Patrick,
To find out what variables do you have you can use fn_print_r($_REQUEST)
where
fn_print_r - good looking cs-cart wrapper of print_r
Actually the variables from profiles.php are not available in profiles.post.php because these are different variable scopes.
So most probably the only variables you will have is global PHP like $_REQUEST $_SERVER etc..
Take a look at discussion or bestsellers add-on - they have products.post.php controllers which work absolutly the same ways a profiles.post.php and any other post controllers.
Is it possible to include a typoscript file via php?
Normally I would include typoscript with this:
<INCLUDE_TYPOSCRIPT: source="FILE:fileadmin/templates/typoscript/setup/1.ts">
But I want to do this just with php and not typoscript. Is that possible?
My Purpose: I want to dynamically load typoscript in my page
This can be achieved by invoking accordant functions at an early stage, e.g. in calling or delegating it in ext_localconf.php. For example, the bookstrap package is loading TypoScript in PHP like this:
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPageTSConfig(
'<INCLUDE_TYPOSCRIPT: source="FILE:EXT:' . $_EXTKEY
. '/Configuration/PageTS/Mod/Wizards/newContentElement.txt">'
);
Please consider, that TypoScript is cached before the actual front-end rendering starts. This means, that you should not modify TypoScript if you're plugin class or controller logic has been called already.
May be you need to return a value from the php function and use typoscript conditions for choosing the typoscript file.
You might try the following (if I get you right):
$typoscriptFile .= file_get_contents($someFile);
$parser = t3lib_div::makeInstance('t3lib_TSparser');
$parser->parse($typoscriptFile);
$tsArray = $parser->setup;
I really don't know how well that will play with anything related to global typoscript though.
If you wanted a complete correct parse, you might be able to pull something like this off if you populated a fresh t3lib_TStemplate instance from $GLOBALS['TSFE']->tmpl and than ran the code above. Might work, never tried.
I have a page ("main.php") which loads content from an external PHP file ("rpc.php"). Using the below syntax on main.php successfully pulls in content from rpc.php:
$("#portfolioContent").load("rpc.php?o="+day+"");
On rpc.php I have an if statement (part of a long switch function), as follows:
if ( $pagename == "home" ) {
break;
}
This break is not occuring because the variable has not been set. rpc.php is used by various parent pages so the variables need to be set on those. On a parent page I have tried using the following code to attempt to set the variable and pass it to rpc.php but to no avail:
$("#portfolioContent").load("rpc.php?o="+day+"$pagename="home"");
Can anybody point me in the right direction? Thank you.
It should be like this,
$("#portfolioContent").load("rpc.php?o="+day+"&pagename=home");
Your syntax is wrong. Try this:
$("#portfolioContent").load("rpc.php?o="+day+"&pagename=home");
Notice i substituted the $ with a &
Cheers
change this line
$("#portfolioContent").load("rpc.php?o="+day+"$pagename="home"");
to this
$("#portfolioContent").load("rpc.php?o="+day+"pagename="home");
then access the variable with $_GET['pagename']
To access variables from the URL in PHP just do:
$_GET['variablename']
For example, with the URL http://www.example.com?hello=hellWorld
echo $_GET['hello'];
would print helloWorld
Also, you use & to separate variables, not $
I'm debugging some client PHP code that has me stumped. As this pseudo-example illustrates, there is code on the receiving end of a form submission that processes the form values, but without ever apparently assigning those values:
(On form submission, where form has fields 'name' and 'position'):
echo "The name is = ". $name;
echo "The position is = ". $position;
This code is part of a large app, and code from other files is called before this. BUT the crucial point is that if I do a search for '$name = ' across the entire codebase it never shows up. How then is it possible that the request variable gets assigned to $name? Is there another way to assign value to a variable in PHP other than $var = value??
My only other clue is that this project uses Smarty, which I don't know anything about.
It may be that the person that created the code was working on a server with register_globals on. What that does, for example, is create regular global variables as the result of a form submission rather than populating the $_POST or $_GET arrays.
If the register_globals directive has been set to true in php.ini, then all POST attributes will also show up as individual variables, in the way you describe. Note that this directive is false by default, and that use of this directive is deprecated.
When you look at the smarty documentation you can see that variables are assigned like this (copied from the linked page):
<?php
$smarty = new Smarty();
$smarty->assign('firstname', 'Doug');
$smarty->assign('lastname', 'Evans');
$smarty->assign('meetingPlace', 'New York');
$smarty->display('index.tpl');
?>
Technically yes there is.
$x = 'name';
$$x = 'harry';
echo 'Yer a wizard '.$name;
(I would be surprised if this was the reason)
I guess your server has register_globals setting on, which automatically generates variables from posted items:
$_POST['foo'] === $foo
Maybe this is another outbreak of the register_globals disease?
This has been thought to have died out, but surfaces again and again!
Sounds to me like someone included those variables with the intention of doing more with them, but never got around to doing so. Unless an include php page is assigning values to those variables, nothing will go in them.
Try turning your error reporting level up, if these variables are being used but haven't been initialised, a warning will be shown
I'm having trouble with using PHP code on my pages, within my body content area. I've searched tirelessly on this site, Drupal's site, and other sites in general, so I apologize if the answer is on this site somewhere, but I can't find it and I need help.
We have a lot of info we reuse throughout our site that I'd like to store in a PHP file as variables. We do this on our site now, but I'm rewriting our whole site to use Drupal. So, for example, we sell software, and I'd like a variable for each of our product URLs for various 'add to cart' buttons on the site. I don't want to have to hardcode the product URL into each link, but rather to seta PHP variable that I can call on any drupal page.
I cannot get anything to work; I've read about several suggestions but none work. I've tried setting the variables as their own block, then calling them from within a page when I create a new page. I can echo the variables on the pages but only within the block they are inside, I cannot call them and get them to echo from other blocks or content areas. I've tried using the global keyword (as per one suggestion) but that didn't work for me.
I hope this makes sense. Other info? I'm using Drupal 6.x, I do have PHP code enabled when creating pages, I do have the PHP filter module enabled, I can get PHP code to render so I know it's working, it's just not working where I need it to be.
I should say (if it's not obvious just from reading this!) I am a Drupal newbie so if anyone can help and try to explain their suggestion as plainly as possible for me, I'd really appreciate it!
Thanks in advance.
EDIT 3/15/11
To try to explain further, I'll post some sample code. I haven't done this yet because there isn't much to show yet, and I thought it might confuse the issue even more.
So, I've made a Drupal 'page' which is for our software trial downloads. The PHP variables that I want to set are for our download links; I want to set them in one place so that if, in the future, the download link needs to change, I only have to do so in one spot. You see, we have download links on various site pages. The same is true of our 'buy now' links. Here is the page code:
<p>Try [product] free for 30 days.</p>
<!--<p>[token_custom_ewintry]</p>-->
<p><?php global $ewintry; ?>Download for Windows PC</p>
<p><?php global $emactry; ?>Download for Mac OS X</p>
<p><?php global $ebbtry; ?>Download for BlackBerry</p>
<?php
$ebbtryprint = variable_get("ebbtry", "default");
print $ebbtryprint;
?>
<p>Download for Windows Mobile</p>
<p><?php global $ipewlstorelink; ?>iPhone, iPad, iPod touch owners: Download [product] on the iTunes App Store. You'll be able to create 10 cards for free to try [product] before you buy!</p>
For this sample I've left in everything I've tried. You'll see my calls to global variables, which never worked. I have the global variables defined in a custom block that I created and placed in my 'content top' region. I learned that apparently nothing from that region is actually accesible to my page's body content, because the calls never worked.
I have a custom token that I made yesterday with the Tokens module; it never worked, but then I read on a different post that by default, tokens are available in the body content area, and I need a special filter. I've yet to find a filter, and so I am not sure this solution will ever work.
I have my call to variable_get. Now, this did work. I have variable_set defined within my template.php page. My value does print using the print call above in my code sample. However, I looked at this page this morning and I don't think that's the answer I need. Because now I'll have to call variable_get on all my pages before I can print anything, right? And that doesn't solve the problem where I wanted to only have to set everything in one place to call anywhere. I tried putting the variable_get call in my custom block, but again I can't access anything in 'content top' from my body content area. The variable_get call prints the value in 'content top' but then it will not re-print below that in the content area.
So maybe that code will help someone to help me. I am going to look in detail at CCK now, as that's the only other suggestion I haven't tried. Thanks in advance if anyone can help.
If you're trying to set a global variable, and then use it within a function/method block, you need to use the global keyword on import:
<?php
// For some reason, this sometimes gives me problems
$foo = 'test';
// So I do this instead, they are equivalent
$GLOBALS['bar'] = 'test';
echo "<p>Global <br/> foo: $foo <br/> bar: $bar</p>";
function globalTest() {
global $foo;
echo "<p>globalTest() <br/> foo: $foo <br/> bar: $bar</p>";
}
globalTest();
function globalBarTest() {
global $foo, $bar;
echo "<p>globalBarTest() <br/> foo: $foo <br/> bar: $bar</p>";
}
globalBarTest();
?>
In action: http://jfcoder.com/test/globals.php
Prints:
Global
foo: test
bar: test
globalTest()
foo: test
bar:
globalBarTest()
foo: test
bar: test
I have always gotten in the habit of setting a global variable using $GLOBALS, I never have any issues doing it this way.
I would caution, though, that setting globally scoped variables is considered harmful (or at least unnecessary), since they are so easy to accidentally overwrite somewhere else in your code (by you and/or someone else).
Your stated approach in the description sounds quite messy; you should be using a database and let Drupal abstract how you organize, set and get the data from the datastore, instead of editing your files and hardcoding some links and data into a PHP file. This is what I'm thinking reading your description, which may not be fair, but I thought I needed to mention it.
EDIT
In Drupal, you can set global variables in the default/settings.php page using variable_set(), and then use variable_get() to get the variable by name.
http://api.drupal.org/api/drupal/sites--default--default.settings.php/6
variable_set('foo','bar');
http://api.drupal.org/api/drupal/includes--theme.inc/function/template_preprocess/6
function yourtemplate_preprocess (&$variables) {
$vars['foo'] = variable_get('foo');
}
EDIT 2
Note the source for the variable_set() function:
<?php
function variable_set($name, $value) {
global $conf;
$serialized_value = serialize($value);
db_query("UPDATE {variable} SET value = '%s' WHERE name = '%s'", $serialized_value, $name);
if (!db_affected_rows()) {
#db_query("INSERT INTO {variable} (name, value) VALUES ('%s', '%s')", $name, $serialized_value);
}
cache_clear_all('variables', 'cache');
$conf[$name] = $value;
}
?>
EDIT
Ok, here is what you can do:
/drupal-root/htdocs/sites/settings.php
Open the settings.php file and at the bottom, set your PHP variables using the $GLOBALS global variables, as so:
$GLOBALS['test1_variable'] = 'test 1 variable';
And then in your template (with the PHP Input Format selected):
<?php
echo "<p>This is my {$GLOBALS['test1_variable']}.</p>";
?>
Or...
<p>This is my short tag <?=$GLOBALS['test1_variable'];?>.</p>
And you should see your variable printed out on the page from the template code. Note the curly braces surrounding the $GLOBALS variable.
If you want to provide additional info that should go with some nodes, you should use CCK to create a content type, that has all the additional infos. With styling inside a template, you can archive almost anything.
If CCK is not siutable (in most cases, it is exactly what you want), you need to implement a _preprocess_ function. This would look like
function yourtemplate_preprocess_page(&$variables) {
$vars['my_custom_var'] = "hello"; //anything can go here
}
Now you have a $my_custom_var in your page-template file available.
Be sure to make yourself familiar with the template system of Drupal (if you haven't already).
It sounds like you are looking for the token_filter module.
My problem is that it isn't ready (in token module) for D7 yet.
