plz anyone me i m beginner in codeigniter in herf passing url with string but the whole can't get in

//Here is html code which pass sting value
index.php/Home/product_show?type='Sugar&Jaggery , Salt'">Sugar & Jaggery , Salt
//controller get sting in type variable but on Sugur got not whole sting and pass type variable to model
public function product_show(){
$type = $_GET['type'];
die(var_dump($type));
$data['testdata']= $this->Globle_model->get_multiple_record($type);
$this->load->view('display_product',$data);
}
//model type variable check the subcategory from database and return to controller
public function get_multiple_record($type){
$this->db->where_in('Subcategory_name',$type);
$get_data = $this->db->get('productmaster');
return $get_data->result_array();
}
//o/p
get this much of string(6) "'Sugar"

Please follow the below way to get all your string into the controller into
$_GET['type'] variable.
Combine all your strings into a single variable using _ into href
Example :
Sugar & Jaggery , Salt
In the controller, I have created one array() with variable subcategory_type .In which key is coming from the view but its value from the database.
Example :
function get_product_type(){
$get_info = $this->input->get();
$subcategory_type = array(
"Sugar_Jaggery_Salt" => "Sugar&Jaggery , Salt"
);
$type_arr = $subcategory_type[$get_info['type']];
$data['testdata']= $this->Globle_model->get_multiple_record($type_arr);
$this->load->view('display_product',$data);
}
In model,
function get_multiple_record($type_array){
$this->db->where_in('Subcategory_name',$type_array);
$get_data = $this->db->get('productmaster');
return $get_data->result_array();
}
Try this and update me in case of anything.

JQuery - How to loop through JSON using each

I have cached the JSON returned from an Ajax call and need to loop through this to display it. I get the error, 'Cannot read property 'title' of undefined'. Can anyone help?
$.each(cache['cat-'+cat], function(i, jd) {
var title= jd.title; //issue is here
)}
When I console.log(cache['cat-'+cat]) I get the below:
Object {
date: "2016-07-28T15:08:03.596Z",
data: '[{"id":471,"title":"Lines and Calls","solution_areas":"lines-calls"}]'
}
When I console.log(jd) within the loop I get the below:
2016-07-28T15:13:14.553Z
if I use console.log(jd.data); I get
undefined
I have tried the below but they don't work either:
var title= jd.data.title;
var title= jd.data[0].title;
Can anyone tell me what I am doing wrong?

The way you are currently using it, each is going to iterate over every property of the cache['cat-'+cat] object, of which there are two, date and data.
So your anonymous function function(i, jd)will be called twice. The first time, jdwill be the value of the date property (a string), the second time it will be the value of the data property (also a string, that happens to be formatted as JSON).
The contents of data need to be parsed before they can be accessed as an object/array, and given that data is formatted as an array, I am guessing that you actually want to iterate over that. Given the example provided, I would change it to:
$.each(JSON.parse(cache['cat-'+cat].data), function(i, jd) {
var title= jd.title;
});

You aren't accessing it properly. And since cache['cat-'+cat] is already the needed object, what's the purpose of $.each? Should be
var title= JSON.parse(cache['cat-'+cat].data)[0].title;
(because the title is in the data, and the data is JSON).
Demo:
var obj = {
date: "2016-07-28T15:08:03.596Z",
data: '[{"id":471,"title":"Lines and Calls","solution_areas":"lines-calls"}]'
};
var title= JSON.parse(obj.data)[0].title;
console.log(title);

Just need to understand what is JSON and what is STRING
cache['cat-'+cat].data return a string that need to convert to JSON before pass to each loop:
var dataCacheReturned = cache['cat-'+cat];
var objCache = dataCacheReturned.data; //Its return a string
objCache = JSON.parse(objCache); //Parse string to json
$.each(objCache, function(i, jd) {
var title = jd.title;
console.log(title);
});

Getting array values in php from jQuery post

I am trying to send an array from jQuery post to PHP.
But I am not getting any values with the below code.
Could anyone help ?
jQuery
$("body").on("click", ".js-form",function(event){
var arr = [];
i = 0;
$('.addcolor').each(function() {
if( $(this).text()=="done"){
arr[i++]= $(this).data('request-id');
}
});
alert(arr);
$.post("../ajax/save_Request.php", {requestids:arr, action:'save_request' })
});
alert(arr)-> prints 11,24,35 (eg)
But I am not getting any values in the following PHP variable.
PHP
$ids = ( isset($_POST['requestids']) ) ? $_POST['requestids'] : 0;

Try with this 'choices[]'
$.post( "test.php", { 'choices[]': [ "Jon", "Susan" ] } );
See more in : jQuery.post and search the key "Pass arrays of data to the server". I think that you missed []. Try it and return me the result.

Try converting the array to a JSON string first, using
var json = JSON.stringify(arr);
Now that it's a JSON string, you can simply pass it through a hidden field. Then, once you get the string back from the PHP page, you can turn it back into an array using
$array = json_decode($arr, true);
where $arr is the JSON string.
I had a similar problem with trying to pass an array from JQuery to another PHP page and this worked for me.

convert param to JSON data inside URL

I have a URL like that and I want to use JSON data coming inside URL
"CUNMXSAKU" : {
"roomCodes" : "DEAL, JRST, JPOV, JSSW, PJRS, PJOV, PJSW, RMOV, RMOF, PRES"
},
My URL
...._results.html?language=en&hotelInfo={CUNMXSAKU:{roomCodes:DEAL,JRST,JPOV,JSSW,PJRS,PJOV,PJSW,RMOV,RMOF,PRES}}
Is it possible to use it ?? I am able to get
var hotelCode = getQueryParameter('hotelInfo');
as a String
{"CUNMXSAKU":{"roomCodes":"DEAL, JRST, JPOV, JSSW, PJRS, PJOV, PJSW, RMOV, RMOF, PRES"}}
But when I am trying
hotelCode.roomCodes , its Undefined.
Please help on this. Is it possible to do with javaScript

When you pull them out of the URL, the params are a string, they're not a javascript object.
Use something like this (in addition to what you have there)
var params = getQueryParameter('hotelinfo');
var hotelCode = JSON.parse(params);
Then hotelCode will actually contain a proper, walkable javascript object.

How to replace ' / ' with '-' inside ObservableArray ? Knockout js

Well i am trying to pass an observable array via ajax call to my controller but i get every value there except date . i get something like '01-01-01' etc .
I found the issue but unable to fix that as i dont know how to replace / with - .
My ObservableArray have around 10 list items each list item holds a many properties out of those startDate holds the date like ("23/10/2014") . i just need something like ("23-10-2014") .
Tought of posting my function's and more i hope thats not required in this case i believe .
Let me explain with bit of code and sample data :
function myarray()
{
var self=this;
self.startDate=ko.observable("");
self.name=ko.observable("");
self.place=ko.observable("");
}
MyObservableArray :
self.Main= ko.observableArray();
In between i do some stuff to load Data into self.Main and i am sending self.Main to controller having data like below :
self.Main[0] holds :
startDate() -->gives you "23/10/2014" //individual observables inside onservable array
name() --> "jhon"
place()--> "croatia"
Likely
self.Main[9] holds :
startDate() --> "29/05/2012"
name() --> "pop"
place()--> "usa"
I am trying like i want to alter the self.Main() and replace the startDate and use the same self.Main to send to my controller . Once after replacing in self.Main when i check date the / should be replaced with - .
Possible solution : i can use a different observable array and push all the VM's of Main into it but i am trying to do on self.Main without using other .
If someone can show some light it is much appreciated .

What I got that you are facing problem in escaping / in replace.
Try this
"(23/10/2014)".replace(/\//g,"-") //returns "(23-10-2014)"
I tried something for you using simple JS
var arr = [{date:"(23/10/2014)"},{date:"(23/10/2014)"},{date:"(23/10/2014)"},{date:"(23/10/2014)"}];
arr.forEach(function(obj){obj.date = obj.date.replace(/\//g,"-")});
console.log(arr) //will print date field as "(23-10-2014)" for all objects.

One solution would be to add a computed value that returns the array with the right values.
self.Main = ko.observableArray([...values here...]);
self.MainComputed = ko.computed(function() {
var computedArray = [];
self.Main().forEach(function(item) {
var newItem = myarray(); //Create a new item.
newItem.name(item.name());
newItem.place(item.place());
newItem.startDate(item.startDate().replace(/\//g,"-"));
computedArray.push(newItem);
});
return computedArray;
});
Then use the computed value in the places where you need the values with -.
I can think of two other ways to solve your issue, when taken into account that you want to use self.Main:
Replace the / with - before setting startDate on your item.
Change startDate to a computed value while storing the original value in another variable.
The first solution should be pretty straight forward (provided that it is a valid solution).
The second solution would look something like this:
function myarray()
{
var self=this;
self.originalStartDate = ko.observable("");
self.name = ko.observable("");
self.place = ko.observable("");
self.startDate = ko.computed(function() {
if(self.originalStartDate()) {
//We can only replace if the value is set.
return self.originalStartDate().replace(/\//g,"-");
}
else {
//If replace was not possible, we return the value as is.
return self.originalStartDate();
}
});
}
Now when you set the values you do something like:
var item = myarray();
item.originalStartDate = "01/01/2014";
Then when you get the value of startDate you would get "01-01-2014".

I haven't used Knockout.js but you can do this with a Javascript replace:
var str = [your array value] ;
var res = str.replace("/", "-");
