I'm making a simple Joomla plugin that loads a CSS file, but I want to load a different file for Joomla 2.5 and 3.2, using a PHP if-else statement. Is it possible to determine the Joomla version of the site using PHP?
You can use the named constant JVERSION or if you need more functions use the JVersion object like:
$j = new JVersion()
echo $j->getLongVersion();
echo $j->$RELEASE;

My website had a older version of wordpress. Recently I upgraded it to the latest version. After that my php code what I write in the editor is keep getting disabled.
The old page which has php code in ti still works. Although in the editor the php codes are disabled. But if I try to save that it stops working. So i cannot update those page. And also I cannot create new page with php code in it
Exec-PHP plugin is installed.
If I write
<?php echo $c; ?>
It converts into
<!--?php echo $c; ?-->
How to fix that
attached image for better understanding.
Another way, which I don't quite recommend, is to follow this direction:
https://wordpress.org/support/topic/exec-php-to-work-in-php-7-needs-this/
This is basically updating the actual plugin, which will surely be overwritten by their next update.
This plugin requires a number of changes to work with php 7.
In exec-php.php
$GLOBALS[‘g_execphp_manager’] =& new ExecPhp_Manager();
must be changed to
$GLOBALS[‘g_execphp_manager’] = new ExecPhp_Manager();
In includes/manager.php from line 36
change each =& to =
In includes/admin.php lines 53,56,57,63,64,79 change =& to =
In includes/cache.php line 22,39 change =& to =
In includes/ajax.php line 64 change =& to =
I don't know about the plugin you use for this. However, I use xyzscripts for the same cause. It creates short-codes for me to use.
Here is an example:
Create your PHP code and get a Tracking Name.
You will then get your short-code as below, note the Tracking Name.
I personally think this is the best way as it allows re-usability and centralized location to update all your scripts.

Thank you all for responding.
Apparently I find the solution by installing the Classic Editor plugin
https://en-gb.wordpress.org/plugins/classic-editor/
It prevents disabling the php code.

Well, I am developing a plugin a and I need to display some stuff from my plugin when TYPO3 page load.
Is there some function how to hook action, like in WordPress when page loads than plugin will execute some controller method? Then this controller will produce some output a HTML, which I would like to dispaly in frontend page. Specially I would like display custom script in the head. So the script should be like this <head>...<script>my content</script>...</head>
Ok, what you probably want to do is to develop a so-called TYPO3 extension - that's what plugins/add-ons are called in TYPO3 (which is the term you will likely find google results for).
To get started fast you can try the TYPO3 extension builder (https://docs.typo3.org/typo3cms/extensions/extension_builder/) - which can generate a skeleton extension for you.
For more information you can also have a look at https://docs.typo3.org/typo3cms/CoreApiReference/latest/ExtensionArchitecture/Index.html which explains the concepts in far more detail.
Additional information is available in https://docs.typo3.org/typo3cms/ExtbaseFluidBook/Index.html
in TYPO3 there is something named plugins, but you should differ to the meaning in other context.
first TYPO3 is a CMS which content is structured in a hierarchical tree of pages. These pages are the basis for navigation. and each page contains individual contentelmenents (CE).
As Susi already told: add ons to TYPO3 are in general 'extensions' which could extend(!) the functinality of TYPO3 in different ways. one way is the definition of (TYPO3-)Plugins. These are special ContentElements which enable to show special information.
While normal CEs have all the information what to show in the record (e.g. Text & Image), plugins can be more flexible.
typical examples are: show a list of records OR one record in detail.
These Plugins can be controlled with typoscript or the plugin-CE could have additional fields to hold information what to display.
For detailed information how a plugin is defined consult the links given by Susi.
And be aware: for security reasons it is not possible to just execute a plain PHP file to echo any output. You need to register your plugin using the API, build your output as string and return the generated HTML as string to the calling function. For beginners the ExtensionBuilder will help you to generate a well formed extension which uses the API to register and output your data.
OK guys, thanks for your answers, but it was not very concrete. I found this solution, is not the best one, but it works! If anybody has better please share.
At first, you have to make a file for the class which will be called from the hook at location /your-plugin-name/Classes/class.tx_contenthook.php. Filename have to have this pattern class.tx_yourname.php Inside we will have a code with one method which will be called by the hook.
class tx_contenthook {
function displayContent(&$params, &$that){
//content of page from param
$content = $params['pObj']->content;
//your content
$inject = '4747474747';
// inject content on
$content = str_replace('</body>', $inject. '</body>', $content);
// save
$params['pObj']->content = $content;
}
}
And next, we have to call it on the hook. So Let's go to /your-plugin-name/ext_localconf.php and add there these two lines, which makes a magic and handles also caching.
// hook is called after caching
$TYPO3_CONF_VARS['SC_OPTIONS']['tslib/class.tslib_fe.php']['contentPostProc-output'][] = 'EXT:' . $_EXTKEY . '/Classes/class.tx_contenthook.php:&tx_contenthook->displayContent';
// hook is called before caching
$TYPO3_CONF_VARS['SC_OPTIONS']['tslib/class.tslib_fe.php']['contentPostProc-all'][] = 'EXT:'. $_EXTKEY .'/Classes/class.tx_contenthook.php:&tx_contenthook->displayContent';
I hope this will help those who struggling with typo3.
I am unable to write PHP code in .tpl file in either ways
I tried <?php echo 'test'; ?>
I also tried {PHP} echo 'test'; {/PHP}
But both returned error
on line 14 "{php}echo "hello!"{/php}" unknown tag "php"
I've not worked with Kohana, but with Smarty 3, use of the php tag is deprecated. You'll need to use the backwards compatibility mode with 3.0. It is highly recommended that all code logic be placed in your controller or php script files, and not your Smarty templates.
If you want to use PHP code in templates, it is suggested you create custom functions or modifiers.
So, basically, the short answer is find where your code (or the Kohana plugin) is instantiating Smarty and change it to use SmartyBC, but be aware that this is highly discouraged.
If you are using Kohana Smarty3 module for Kohana, these code lines should help set you in the right direction.
I have a complex php application which I want to include in a typo3 page. I allready found something like this:
page.headerData.20 = PHP_SCRIPT_EXT
page.headerData.20.file = fileadmin/phpScript.inc
...but this inserts the file to template, I just want to show it on one single page instead of content. The application is currently included as an iFrame (same domain) but that's not the best way because the window doesn't resize.
In also think abouth to convert the whole app to typo3 plugin, but I'm very new to typo3 so I don't now how to start. Is there a guide for converting plain php to typo3 plugin?
Hi you can use a simple user extension.
Some where in Typoscript Setup:
includeLibs.mystuff = path_to_file/my_user_class.php
lib.mystuff = USER_INT
lib.mystuff {
userFunc =user_myclassname->main
var_to_pass_at_class=test
}
--
Now you can replace the subpart with dynamic content (depends on your TYPO3 configuration)
+- page.10.subparts.CONTENT<lib.mystuff
--
File: my_user_class.php
<?php
class user_myclassname {
function main($content,$conf){
global $TSFE;
return $conf['var_to_pass_at_class']; //returns test
}
}
How can a get a object variable from a remote XML file, for example this one ?
In PHP5 it works fine with simplexml_load_file(), but I need this to work in PHP 4 also. How can I do that?
Or is there any built-in WordPress function that can load xml files? I tried using the WP's SimplePie class, but I get a weird object variable (with incorectly named fields etc).
If you want to use the smipleXML functions in PHP4 include this class ( I have used it and it works like a charm)
