to
http://dev.hello.com/about/updateVision/this-is-test-edit/
i have no idea how to make looks like that anyone can help please
thanks !
This all depends on you database structure. I would introduce a field called reference or slug. This will contain a unique string for your record. When creating the record you can use the url_title function to remove spaces as mentioned by #Rooneyl
This reference must be unique so I would create a function that creates a reference in a loop, checks it against the database. When it returns false, it is unique.
public function unique_reference($name)
{
$name = trim(strtolower($name));
$unique_reference = url_title($name);
$counter = '';
do {
$result = $this->db->select('id')
->from('your_table')
->where('reference', $unique_reference)
->get()->row();
if ($result)
$counter++;
$unique_reference = url_title(trim("{$name} {$counter}"));
} while ($result);
return $unique_reference;
}
You can then retrieve record using this unique value

If you are thinking this question is a beginner's question, maybe you are right. But really I was confused.
In my code, I want to know if saving a model is successful or not.
$model = Model::find(1);
$model->attr = $someVale;
$saveStatus = $model->save()
So, I think $saveStatus must show me if the saving is successful or not, But, now, the model is saved in the database while the $saveStatus value is NULL.
I am using Laravel 7;
save() will return a boolean, saved or not saved. So you can either do:
$model = new Model();
$model->attr = $value;
$saved = $model->save();
if(!$saved){
//Do something
}
Or directly save in the if:
if(!$model->save()){
//Do something
}
Please read those documentation from Laravel api section.
https://laravel.com/api/5.8/Illuminate/Database/Eloquent/Model.html#method_getChanges
From here you can get many option to know current object was modified or not.
Also you can check this,
Laravel Eloquent update just if changes have been made
For Create object,
those option can helpful,
You can check the public attribute $exists on your model
if ($model->exists) {
// Model exists in the database
}
You can check for the models id (since that's only available after the record is saved and the newly created id is returned)
if(!$model->id){
App::abort(500, 'Some Error');
}

UPDATE:
I think now I am literally just trying to get a database value into my component php files, but again, there seems to be very little documentation that can give an example of a function that will return this info like there is in Wordpress.
So I have a table called membersarea_countries that will have records of differnt countries I want to store values for.
I've read about JTable and other things, but how can I simply just bring back the records from this table?
$row = JTable::getInstance('membersarea_countries', 'Table', array());
But this returns a boolean of 0.
I'd really appreciate some help if anyone can.
===
I've been following what several online guides explain, which are all pretty much the same thing, but I never seem to return the values that I'm expecting.
In Components > Members Area (my component), I have a table set up to allow me to enter a record for each country, and then store a uniqueRef, signature, and URL within that record. (for GeoIP purposes).
I've created the first record, however when I try to use the following code, which the tutorials suggest, I don't see any of my fields within this:
$app = JFactory::getApplication();
$params = $app->getParams();
$uniqueRef = $params->get('uniquereference');
$signature = $params->get('signature');
This is all I see in NetBeans:
There's nothing about $app, and no sign of the fields I've got in the Joomla backend.
I don't understand what's happening, or exactly what I should be doing here. Wordpress uses a simple get_option function. Can anyone try and help me?
Below is the link to the detailed document about JTable -
https://docs.joomla.org/Using_the_JTable_class
Firstly you need to create JTable instance using below code and also change table file name to membersareacountries.php
JTable::addIncludePath(JPATH_ADMINISTRATOR . '/components/com_membersarea/tables');
$row = JTable::getInstance('Membersareacountries', 'Table', array());
JTable Class in this file /administrator/components/com_membersarea/tables/membersareacountries.php-
<?php
defined('_JEXEC') or die();
class TableMembersareacountries extends JTable
{
public function __construct($db)
{
parent::__construct( '#__membersarea_countrie', 'id', $db );
}
}
Then you can use load method to get any records. This accepts primary key value of that table -
$id = 1;//change id as per your record
$row->load($id);
//read data
echo $row->id;
echo $row->title;
I am trying to update a table with the path of the uploaded file so that it is easy to email a download link but I cannot seem to get the id.
My component looks like this:
public function onAddJob() {
$manual = new Job();
$manual->company = Input::get('company_name');
$manual->ordered_by = Input::get('client_name');
$manual->ordered_by_email = Input::get('client_email');
$manual->emergency_no = Input::get('emergency_no');
$manual->instructions = Input::get('instructions');
$manual->project_name = Input::get('project_name');
$manual->fileupload = Input::file('fileuploader');
$manual->save();
$this->id = $this->property('id');
Db::table('manual_jobs')->where('id', $this->id)->update(['path' => $manual->fileupload->getPath()]);
Everything saves fine but path is not updated as I am not getting the id correctly, can anyone help show me where I am noobing?
The id component is defined by the variable $primaryKey on the model
default the primary key is 'id' corresponding to a database table field named id
You can overwrite the default keyname by setting $primaryKey to another key
class Foo extends Model {
$primaryKey = 'foo_id';
}
Why i'm explaining this is because you don't need to know the name of the field.
What you can do is:
$foo = new Foo();
$foo->bar = 'baz';
$foo->save();
echo $foo->getKey();
echo $foo->getAttribute($foo->getKeyName());
echo $foo->{$foo->primaryKey}
They will all print out the newly created primary key on the object.
getkey() returns the value of the primary key.
getKeyName() returns the name of the primary key field defined in the model
The solution was a lot simpler than I thought.
What I was looking for was this:
$manual->id
So the update query looks like this:
Db::table('manual_jobs')->where('id', $manual->id)->update(['path' => $manual->fileupload->getPath()]);
Its because when you call ajax request it will not call pageCycle.
as a result your code in page will not executed.
your code on page may be look like this one
{% component 'yourComponent' id=someID %}
but this code is not executed during ajax call
to execute page code during ajax call you need to explicitly call $this->controller->pageCycle()
so new code will look like
public function onAddJob() {
// we are calling page code explicitly
$this->controller->pageCycle();
$manual = new Job();
$manual->company = Input::get('company_name');
$manual->ordered_by = Input::get('client_name');
... other code
}

I am trying to load a page dynamically based on the database results however I have no idea how to implement this into codeigniter.
I have got a controller:
function history()
{
//here is code that gets all rows in database where uid = myid
}
Now in the view for this controller I would like to have a link for each of these rows that will open say website.com/page/history?fid=myuniquestring however where I am getting is stuck is how exactly I can load up this page and have the controller get the string. And then do a database query and load a different view if the string exsists, and also retrieve that string.
So something like:
function history$somestring()
{
if($somestring){
//I will load a different view and pass $somestring into it
} else {
//here is code that gets all rows in database where uid = myid
}
}
What I don't understand is how I can detect if $somestring is at the end of the url for this controller and then be able to work with it if it exists.
Any help/advice greatly appreciated.
For example, if your url is :
http://base_url/controller/history/1
Say, 1 be the id, then you retrieve the id as follows:
function history(){
if( $this->uri->segment(3) ){ #if you get an id in the third segment of the url
// load your page here
$id = $this->uri->segment(3); #get the id from the url and load the page
}else{
//here is code that gets all rows in database where uid = myid and load the listing view
}
}
You should generate urls like website.com/page/history/myuniquestring and then declare controller action as:
function history($somestring)
{
if($somestring){
//I will load a different view and pass $somestring into it
} else {
//here is code that gets all rows in database where uid = myid
}
}
There are a lot of ways you can just expect this from your URI segments, I'm going to give a very generic example. Below, we have a controller function that takes two optional arguments from the given URI, a string, and an ID:
public function history($string = NULL, $uid = NULL)
{
$viewData = array('uid' => NULL, 'string' => NULL);
$viewName = 'default';
if ($string !== NULL) {
$vieData['string'] = $string;
$viewName = 'test_one';
}
if ($uid !== NULL) {
$viewData['uid'] = $uid;
}
$this->load->view($viewName, $viewData);
}
The actual URL would be something like:
example.com/history/somestring/123
You then know clearly both in your controller and view which, if any were set (perhaps you need to load a model and do a query if a string is passed, etc.
You could also do this in an if / else if / else block if that made more sense, I couldn't quite tell what you were trying to put together from your example. Just be careful to deal with none, one or both values being passed.
The more efficient version of that function is:
public function history($string = NULL, $uid = NULL)
{
if ($string !== NULL):
$viewName = 'test_one';
// load a model? do a query?
else:
$viewName = 'default';
endif;
// Make sure to also deal with neither being set - this is just example code
$this->load->view($viewName, array('string' => $string, 'uid' => $uid));
}
The expanded version just does a simpler job at illustrating how segments work. You can also examine the given URI directly using the CI URI Class (segment() being the most common method). Using that to see if a given segment was passed, you don't have to set default arguments in the controller method.
As I said, a bunch of ways of going about it :)
isn't this the right method to get Name of logged in customer?
<?php echo Mage::helper('customer')->getCustomer()->getName(); ?>
I have a website with live chat functionality. Yesterday I have been asked to pass email address and the name of the logged into the user into the Javascript Tracking variable code placed in the head section of the website. So that the operators could see who is on the website and whom are they talking to without any need to ask about their information.
So I passed the information from Magento into the Javascript code but now I see this very strange thing happening. For example,
If I am logged in with credentials Name = John Email =
john12#yahoo.com
Then This name and email variable values are changing with the change of pages. For example if I click on any product page the variable values which I am passing changes to some other user's information.
Name becomes Ricky Email becomes ricky23#gmail.com
this variable values are kept on changing back to john and from john to something else with the change of pages. So operator does not have any idea whom are they talking because the values are kept on changing. Also, user ricky or who ever it changes to also exist in the database. so it is picking up random person from the database.
This is what i did to pass the code to javascript. Please let me know if that is not the right code to pass the information. Please check the php code I am using to fetch information from Magento. Roughly, I receive incorrect value once in 5 times. Please provide some assistance. Thanks in advance.
<?php
$customer = Mage::getSingleton('customer/session')->getCustomer();
$email = $customer->getEmail();
$firstname = $customer->getFirstname();
$lastname= $customer->getLastname();
$name = $firstname . ' ' . $lastname;
?>
<script type="text/javascript">
if (typeof(lpMTagConfig) == "undefined"){ lpMTagConfig = {};}
if (typeof(lpMTagConfig.visitorVar) == "undefined"){ lpMTagConfig.visitorVar = [];}
lpMTagConfig.visitorVar[lpMTagConfig.visitorVar.length] = 'Email=<?php echo $email; ?>';
lpMTagConfig.visitorVar[lpMTagConfig.visitorVar.length] = 'Name=<?php echo $name; ?>';
</script>
I'm also attaching a snap shot
I'd be interested to hear how you're adding this code to the page? Is it in it's own block, or are you adding it to footer.phtml, or similar? If your adding to an existing block be sure to check the block caching settings of that template.
To confirm the caching hypothesis I'd ask the following:
Do you get the same name, all the time, on the same page? When you refresh the page, do you get the same name and email in the Javascript?
Does the problem persist with caching disabled?
This doesn't sound like a singleton problem at all. Each execution of the PHP script is isolated from the others, serving one page request. There's no chance of another customer's object moving between invokations of the script.
It is a matter of understanding the singleton pattern. If you call your code twice:
$customer_1 = Mage::helper('customer')->getCustomer()->getName();
$customer_2 = Mage::helper('customer')->getCustomer()->getName();
you get two different instances of the object. But... if one of them has already implemented a singleton pattern in its constructor or has implemented a singleton getInstance then both objects will actually point to the same thing.
Looking at the customer/helper/Data.php code you can see the function
public function getCustomer()
{
if (empty($this->_customer)) {
$this->_customer = Mage::getSingleton('customer/session')->getCustomer();
}
return $this->_customer;
}
That means that in one of the cases singleton is already implemented/called and in other one - not as the property is already set.
The correct way to work with quote/customer/cart in order to get always the correct data is always to use the singleton pattern.
So using this:
$customer = Mage::getSingleton('customer/session')->getCustomer();
always guarantee that you get the correct customer in that session. And as may be you know singleton pattern is based on registry pattern in app/Mage.php:
public static function getSingleton($modelClass='', array $arguments=array())
{
$registryKey = '_singleton/'.$modelClass;
if (!self::registry($registryKey)) {
self::register($registryKey, self::getModel($modelClass, $arguments));
}
return self::registry($registryKey);
}
and looking at app/Mage.php:
public static function register($key, $value, $graceful = false)
{
if (isset(self::$_registry[$key])) {
if ($graceful) {
return;
}
self::throwException('Mage registry key "'.$key.'" already exists');
}
self::$_registry[$key] = $value;
}
...
public static function registry($key)
{
if (isset(self::$_registry[$key])) {
return self::$_registry[$key];
}
return null;
}
you can see that Magento checks is it is already set. If so, Magento will either throw an Exception, which is the default behavior or return null.
Hope this will help you to understand the issue you face.
I have sorted this out. I have moved the code from footer.phtml to head.phtml and it's working fine now.Values are not changing anymore. If anyone know the logic behind please post and I will change my answer. So far this is working.
