Iam unable to understand following:
$this->db->select('1', FALSE);
Can some one elaborate it in simple way.
The first parameter is the field names or values in your case 1 from your table, the second parameter FALSE prevents the first parameter being wrapped in backticks. You'd use this is you were nesting a sub query as the first parameter.
For further information see the Codigniter docs which are incredibly useful.

I am using sys.person to capture the person's name. Is there any way for just 'john' and not the entire {"name": "john"} to show instead? I want to avoid sys.given-name and sys.last-name since dialogflow says they are deprecated.
Do you have your entity configured as a list? If it is a list, you probably have to output the parameter like $session.params.name[0].name.
If it's not a list, $session.params.name.name would work, but in that case I suggest you change the entity name to person, as it would be more readable to see $session.params.person.name
From your screenshot, it looks like your parameter is an isList parameter.
I have checked today the behavior of static responses when referencing isList parameters and it seems that we can now display the list of values for a certain parameter without the array index in the responses using the format: $session.params.parameter-id.
In your case, it would be:
$session.params.name.
In addition, if you want to reference a specific array index in an isList parameter, you can use the format $session.params.parameter-id[i]. In your case, it would be $session.params.name[0]
or if you want to get the original value you can reference it as $session.params.name[0].original
So there is this HUGE JSON that I am loading from a file and than I run it through lr_eval_string and save it to a parameter. This parameter is later used as a body in one of my REST calls.
I use lr_eval_string to dynamically replace different values in that JSON.
Now here is the problem, one of the values that I replace is unique and generated by a c function. This value appears numerous times in that JSON and needs to be unique each time, yet I am only able to call that c function once at the beginning of the action. The result is that all values end up being equal...
So my question is: how can I call my function each time this unique value appears? I am talking about functionality similar to "Update value on: Each occurrence" that is available on the Parameters section.
I see an option called "User Defined Function" in parameters which I guess could do what I am looking for yet I couldn't find any good tutorial on how to actually use this functionality. Is user defined action the way to go, is there any other solution?
Any help would be highly appreciated! :)
I want to populate my select box from the Laravel IoC Container.
App\Http\Utilities\BillingHelper.php
views/billing/create.blade.php
views/billing/edit.blade.php
Create the table:
Now, instead of the value, i want to display some flags and currency symbols.
Should i use mutators?
Problem
If i use mutators, when i open the edit page, i see always the first value selected, from the BillingHelper, instead of the choosen one.
Any help? Thanks.
I know it should be a comment, but I have no reputation.
What if, on you edit page, you replace null on Form::select with $client->language and $client->currency.
I know that you area binding the values with Form::Model. But worth a try.
When you use mutators the matching won't occur anymore. You'll have to use a matching static array according to the values you'll return. (the flags)
You can make it work if you make a mutator for saving the data also and simplify again to the ['it', 'en', 'lv'], otherwise your saved data will differ and the initial mutator won't work the second time. You can still make a one-time-only test.
This is why:
Your form binding is using $bill->language to retrieve the actual stored data, and compare it with the values in your $bill::lang static array. If no match found, than the first value will be always selected.
Can you provide the the currency and language fields definition in the migration for the bill?
Also retrive your values from your bills DB and paste them here for language and currency. They must be in the defined static sets.
Laravel has a way of skipping the accessor/mutator by using
$model->getOriginal('data_field').
The "getOriginal()" gets the model's original attribute values.
I got a big search module in my Codeigniter project. Well simply I am passing variable to a view like
<a href=<?php echo site_url('controller/view/1'); ?>>View List</a>
And fetching its data in controller like
$id=$this->uri->segment(3);
For pagination
http://wwww.site.com/controller/view/<filter id>/<page from>
This is working perfectly in the case of simple query.
Now I got some more filter quires like
Country
State
City
Customer type
etc etc
then the url should be
http://wwww.site.com/controller/view/1/id2/id3/i4/id5
Is this the correct way to do the process ? If not please give a little advice...
I am new to codeigniter
The problem you are facing i have recently found a solution for this.
When you are first sending parameters through url use POST instead.
When you get the parameters you can pass them to session in a variable
type. Next time when you paginate get the type value from session and
put it in your query to get the desired result.
If you have more than 1 parameters you can put them in sessions and
unset them on certain conditions so that they are not called in every query.
I think the best approach here is to create another method in the controller something like filtered_view that accepts a filter_id and a page number, and that methode will fetch the data from the database with the provided filter and you'll use your pagination class as usual.
Hope this help.
This question might seem stupid but i nonetheless i believe it's a worth asking questioin.
I work on some web application when we use tags which are attached to articles.
When adding new article users provides a list of tags he wish to associate with his new article.
So when the form is submitted and my MVC controller processes request i have a string with tags from the form. I split the tags string and i get an array of tag words. Then i need a
list o tags ids from db. So i came up with a method that takes a list of tag words and checks if each tag already exists in db. If given tag is already in db then tag's id is appended to result array. If tag does not exist in db it is created and then id of just created tag is appended to result array.
My question is: what is the best name for such a method? This method creates tags only if necessary and returns list of tags' ids.
I tried this names, but none of them looks right to me:
fetchTagsIds(List tagWordsList)
createOrFindsTagsIds(List tagWordsList)
obtainTagsIds(List tagWordsList)
I need a name that really reflects what the method does. Thanks for your help :)
I'd drop the "s" in "Tags". So that the method is:
FetchTagIds(List tagWordsList)
IdsOfTags. That it creates them is an implementation detail (as is the fact that it uses a relational database in the first place). All that matters is that it gives you unique ids for tags (e.g. it could also hash them with a perfect hash function, or lookup an ID in the web.
If you're having trouble coming up with a name that accurately describes what your method does, that could be because you method does too much. Perhaps it would be better to refactor it into two:
findTagsByName(List tagNames) would return a list of Tag objects based on list of names you pass in
persistTags(List tags) - or saveTags(), or createTags() - would persist a list of Tag objects.
getTagIDs?
Get suggests that the code will do something to get an ID when one doesn't exist to fetch.
