So I'm just trying to use xeditable (http://vitalets.github.io/x-editable/docs.html#gettingstarted) to make changes to my database via AJAX.
Since I'm new to this concept and I'm (forcefully) working with PHP for the first time, I need some help.
I setup the frontend part, and a script called (say) script.php is handling the data for me (I need to write the new value in my database).
I can't really understand what to do in the script. Can someone guide me towards it? The docs above don't really do it for me.
Looking in a project I worked on a few months back (sorry about the mysql_ stuff – not my choice!)
Something like:
<?
include your/database/connection_stuff.php;
// Can't remember if x-editable passes the table in as well or not
$table = mysql_real_escape_string($_GET['table']);
// If not,
$table = 'name_of_table';
$value = mysql_real_escape_string($_POST['value']);
$name = mysql_real_escape_string($_POST['name']);
$pk = mysql_real_escape_string($_POST['pk']);
$result = mysql_query("UPDATE `$table` SET `$name` = '$value' WHERE id = '$pk'");
?>
Will do the trick.

laravel 8 pagination using this style for links
www.website.com/huawei?page=3
how i can make it like this?
www.website.com/huawei/3
There is not specific way. so we need to play around the existing things.
But I had made it one of my application a long time before not tested much.
may be there is much better way also to achieve it.
so may it will work same for you. Please check below way to do it as pretty url.
Route :
Route::get('/articles/page/{page_number?}', function($page_number=1){
$per_page = 1;
Articles::resolveConnection()->getPaginator()->setCurrentPage($page_number);
$articles = Articles::orderBy('created_at', 'desc')->paginate($per_page);
return View::make('pages/articles')->with('articles', $articles);
});
View :
$links = $articles->links();
$patterns = array();
$patterns[] = '/'.$articles->getCurrentPage().'\?page=/';
$replacements = array();
$replacements[] = '';
echo preg_replace($patterns, $replacements, $links);
Best Solution I had found : Please use below package for laravel which help you.

I'm building a custom component and I just want to get a value from the global config in my controller. I can't find any information about how to do this.
Something like...
$config = JFactory::getConfig();
$this->_db = $config->get('db');
The documentation on how to do it is slightly outdated:
http://docs.joomla.org/JFactory/getConfig
But if you check the code they actually drop the ampersand function:
https://github.com/joomla/joomla-cms/blob/staging/components/com_users/models/registration.php
$config = JFactory::getConfig();
$fromname = $config->get('fromname');
Also if you are trying to connect to the database you really can just use the DB object from JFactory.
$db = JFactory::getDbo();
Learn more about properly connecting to the database here:
http://docs.joomla.org/Accessing_the_database_using_JDatabase
Since Joomla 3.2:
JFactory::getApplication()->get($varname, $default);
See the reference
I have code like this in my Joomla plugin:
$some_id = $_GET["someid"];
$db = JFactory::getDBO();
$db->setQuery("SELECT * FROM #__table WHERE id = '$some_id'");
$result = $db->loadRow();
Does Joomla sanitize this automatically, or i need to do something (and what) to sanitize this query ? Using Joomla 2.5.
There is no need to sanitize database queries when using Joomla. The information you are pulling down is the information that has put put there or already there, and thus you don't want to change. I would also recommend using Joomla 2.5 coding standards to make database queries, like so:
$db = JFactory::getDbo();
$query = $db->getQuery(true);
$query->select($db->quoteName('*'))
->from($db->quoteName('#__table'))
->where($db->quoteName('id') . ' = ' . $db->quote($some_id));
$db->setQuery($query);
$rows = $db->loadRow(); //or loadResult()
The only time I have ever needed to sanitize (so to speak) something was when handling files, in which case I used JFile::makeSafe();.
Please take a look at you will get your answer
Secure coding guidelines
http://docs.joomla.org/Secure_coding_guidelines
Take a look at JInput and this corresponding documentation
Filter example:
$jinput = JFactory::getApplication()->input;
$some_id = $jinput->get('someid', '', 'string');
I need to add a custom option to all products as they get saved. For that I need to find the function that inserts the products into the database, which I'm not able to find.
Please, any help would be appreciated.
thanx
$client = new SoapClient('http://www.magentolocal.it/api/?wsdl');
$session = $client->login('productloader', '1234567890');
$sku = "123456";
$attrs['name'] = "Template #1";
$attrs['description'] = "This is the first template.";
$attrs['short_description'] = "This is the short description of the template";
$attrs['websites'] = array('1');
$attrs['price'] = "11.53";
$attrs['categories'] = array('35');
$attrs['images'] = array()
$result = $client->call($session, 'catalog_product.create', array('simple', '63', $sku, $attrs));
echo $result;
$client->endSession($session);
Magento's EAV system is pretty strung out among several files, so you won't find a single function that accomplishes what you want. If you did go looking for it, and changed it, you would also be changing the same save method that mostly every other object in Magento uses, which is probably not what you want.
To do what you want, try setting up an observer/listener on the events that catalog products use when saving, namely catalog_product_save_before or catalog_product_save_after. That way, you don't have to hack the framework.
Hope that helps!
Thanks,

How about http://www.magentocommerce.com/wiki/doc/webservices-api/api/catalog_product#catalog_product.create?
can anyone give me an example on how to create Sessions and write data to it. I've seen syntax on how to write data to a session using write command. But how to create a session and retrieve the values in it.
In my application, I have two data, form_id and user_id that needs to be used in all the page requests. So how do I save it as a session variable and use it across the application?
EDIT
function register()
{
$userId=$this->User->registerUser($this->data);
$this->Session->write('User.UserId',$userId);
//echo "session".$this->Session->read('User.UserId');
$this->User->data=$this->data;
if (!$this->User->validates())
{
$this->Flash('Please enter valid inputs','/forms' );
return;
}
$this->Flash('User account created','/forms/homepage/'.$userId);
}
How to use the session variable 'User.UserId' instead of $userId in $this->Flash('User account created','/forms/homepage/'.$userId);
And can I use this variable in all my view files,because in all the page requests I also pass the userId?
EDIT 2
I have 2 controllers,user and form. I write the userid to a session variable in the users_controller. I have a view file called homepage.ctp,whose action is in the forms_controller. Now how can I use the session variable defined in the users_controller in the homepage? Sorry if I am asking silly questions. I went through the cakebook,but my doubts weren't cleared. I'm also trying trial and error method of coding,so please help me.
EDIT 3
I have a session variable 'uid' which is the user id in the home page action of a controller.
$this->Session->write('uid',$this->data['Form']['created_by']);
I need the same variable in the design action method of the same controller.
When I give
$uid=$this->Session->read('uid');
echo "uid: ".$uid;
the value is not echoed.
Can't I use the session variable in the same controller?
The bakery is your best friend:
http://book.cakephp.org/view/398/Methods
All your session read/writes belong in the controller:
$this->Session->write('Person.eyeColor', 'Green');
echo $this->Session->read('Person.eyeColor'); // Green
In cake php you can create session like this
$this->request->session()->write('user_id', 10);
and you can read session value like this
echo $this->request->session()->read('user_id');
Super Simple!
You don't have to write any code to create session, they are already built in. Then you just use the read and write sessions as mentioned above. Also see here for more details:
http://book.cakephp.org/2.0/en/core-libraries/components/sessions.html
Used in Controllers
http://book.cakephp.org/2.0/en/core-libraries/helpers/session.html
Used in Views
cakephp 4 example of session usage in controllers, views and cells
$session = $this->request->getSession();
$session->write('abc', 'apple');
echo $session->read('abc');
In this case it would be:
$this->Flash('User account created','/forms/homepage/'.$this->Session->read('User.UserId'));
and your second question is anwered by Jason Miy (http://api.cakephp.org/class/session-helper). You can simply use this in your view:
$userId = $session->read('User.UserId');
Reading the appropriate cookbook pages slowly and carefully usually helps a lot...
I found out the reason why the uid wasn't being echoed(edit 3 part of the question).
It is due to a silly mistake, had a white space after the end tag ?> in the controller. Now it is working fine.
when I have strange session behavior, and this help me.
MODEL:
function clearAllDBCache() {
$db =& ConnectionManager::getDataSource($this->useDbConfig);
$db->_queryCache = array();
}
`
Acess your Helper SessionHelper in lib/Cake/View/Helper/SessionHelper.php and add the method:
public function write($name = null) {
return CakeSession::write($name);
}
