Codeigniter I want to increase +1 when loading page. but the query does 0
'views + 1' and I did 10 no problem.
It didn't make sense to throw the query for views.
function get_views()
{
$this->db->set('views', 'views+1');
$this->db->where('Id', 1);
$this->db->update('pages'); // gives UPDATE mytable SET field = field+1 WHERE id = 2
}
You need to pass a third parameter as false like below:
$this->db->set('views', 'views+1', FALSE);
The Third Parameter tells CodeIgniter not to protect the generated query with backticks. In your case the final query will be
UPDATE pages SET views = views + 1 WHERE Id = '1';

Hello I am a beginner in using Codeigniter. What I want is to update a data in Codeigniter with an OR condition to the ID.
Here is my MySQL query that I want to make happen:
Update message_received SET is_read = 1 WHERE msg_id = 3 OR parent_id = 3
I tried something like this:
$this->query->update_array('message_received', array('msg_id' => $_POST['read_my_message'],'parent_id' => $_POST['read_my_message']) , array('is_read'=>1));
You can use or_where to apply OR condition in CodeIgniter, I've written a possible solution for your question(Reference).
See if it helps you.
$msg = $this->input->post('read_my_message'); // get the post data
$this->db->set('is_read', 1); // set the value of column
$this->db->where('msg_id', $msg); // first condition
$this->db->or_where('parent_id', $msg); // second contion
$this->db->update('message_received'); // table name
// Produces:
/* UPDATE `message_received` SET `is_read` = 1 WHERE `msg_id` = '$msg' OR `parent_id` = '$msg' */
You can apply OR. The references https://www.codeigniter.com/userguide3/database/query_builder.html
I use Laravel 6.12, I have this request :
$queryJob = DB::table('jobs as j')->join('job_translations as jt', 'j.id', 'jt.job_id')
->whereNull('j.deleted_at')
->whereNull('jt.deleted_at')
->select('j.id', 'j.short_name', 'j.status', DB::raw("case when j.short_name = '{$request->short_name}' then 0 else 1 end"))
->distinct();
$jobs = $queryJob->paginate($qtyItemsPerPage);
The results displays an error for the total :
The total = 3, but as you can see the data contains only 2 elements.
I read here that when using a distinct, I must be clear on which column the total must be calculated: distinct() with pagination() in laravel 5.2 not working
So I modified my query like that:
$jobs = $queryJob->paginate($qtyItemsPerPage, ['j.*']);
But without success, the total is still wrong.
Hoping that I don't misunderstand your DB and relations structure and purpose of your query perhaps this will avoid using distinct or groupBy altogether?
$shortname = $request->input('short_name');
$queryJob = Job::with('job_translations')->select('id','short_name',
'status', DB::raw("case when short_name = '" . $shortname . "'
then 0 else 1 end")
->paginate($qtyItemsPerPage);
Pagination can be easily manually added with skip and take in case you need to use groupBy
$queryJob->skip(($page - 1) * $qtyItemsPerPage)->take($qtyItemsPerPage)->get();
The solution for me was to pass a field name to the distinct() method.
With your example:
$queryJob = DB::table('jobs as j')
// joins, where and other chained methods go here
->distinct('j.id')

I return the values 10 by 10 in my table using the tablesorterPager.
This ajaxProcessing code treat my values returned by json.
When I use the filters (filter-select or search), it's only applied on the 10 values returned by my controller and I want to apply it to the total rows.
ajaxProcessing: function(data){
if (data && data.hasOwnProperty('rows')) {
var r, row, c, d = data.rows,
total = data.total_rows,
headers = data.headers,
rows = [],
len = total;
for ( r=0; r < len; r++ ) {
row = [];
for ( c in d[r] ) {
if (typeof(c) === "string") {
row.push(d[r][c]);
}
}
rows.push(row);
}
return [ total, rows, headers ];
}
},
Have you some ideas?
Thank you for your time.
Sounds like you may need to use the ajaxUrl and customAjaxUrl options. With the ajaxUrl option you set how the filter url parameters are formatted when a filter is activated. With customAjaxUrl you can convert the filter url parameters set in ajaxURl to whatever you need to properly filter the 1000 records according to how your program works.
For example, let's say you have ajaxUrl set as follows:
ajaxUrl: dataquery.php?{filter:filter}
Let's say you type "John" into the first column filter in the table. This will cause customAjaxUrl to run and the url variable will be dataquery.php?filter[0]=John. Let's say that for the query to properly filter your 1000 records you need the url query to be dataquery.php?name=John. To make that conversion, add coding within the customAjaxUrl option to change filter[0] to name and return the converted url dataquery.php?name=John. This will then filter the 1000 records and return the filtered result to your table.
You may not be using php but the concept would still apply.
I read on many forums about how to implement a solution for view pagionation, but I didn't solve it.
I created $$ViewTemplateDefault containing some personalized hotspotbuttons for Next, Previous and a text field $$ViewBody. ( or, alternatively, an embedded view ).
Any tips and help will be really appreciated.
I will explain in a couple words, just to be clear:
So, initially: the first 30 lines will appear => in a right corner: Page 1.
If Next is clicked => the next 30 lines => Page 2. and so on.
Here is a working solution for categorized views too. It calculates the current page number based on the previous page number and uses cookies.
Add to your form a Path-Thru HTML text <span id="pageNumber"></span > for the page number:
and add following code to form's onLoad event as Web/JavaScript:
function getURLParameter(parameter) {
return decodeURIComponent((new RegExp('[?|&]' + parameter + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [, ""])[1].replace(/\+/g, '%20')) || null;
}
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) {
var c = ca[i].trim();
if (c.indexOf(name)==0) return c.substring(name.length,c.length);
}
return "";
}
function compareStart(start1, start2) {
var list1 = start1.split(".");
var list2 = start2.split(".");
for (i=0; i <100; i++) {
var value1 = list1[i];
var value2 = list2[i];
if (value1 == null) {
return value2 == null ? 0 : -1;
} else if (value2 == null) {
return 1;
}
value1 = Math.round(value1);
value2 = Math.round(value2);
if (value1 !== value2) {
return value1 < value2 ? -1 : 1;
}
}
}
var start = getURLParameter("Start");
var page = "1";
if (start == null || start === "1") {
window.name = Math.floor((Math.random()*10000)+1);
start = "1";
} else {
page = getCookie("page" + window.name);
var oldStart = getCookie("start" + window.name);
page = Math.round(page) + compareStart(start, oldStart);
}
document.getElementById('pageNumber').innerHTML = page;
document.cookie = "page" + window.name + "=" + page;
document.cookie = "start" + window.name + "=" + start;
How does it work?
The commands #DbCommand("Domino"; "ViewNextPage") and #DbCommand("Domino"; "ViewPreviousPage") return an URL with parameter "&Start=". This is the row number in view where the current page starts. For categorized views they return a hierarchical number like "&Start=1.2.4.2". That means that the view starts at the first main topic, subtopic 2, subsubtopic 4, document 2.
This parameter "&Start=" gives us the possibility to recognize if user pressed "prev" or "next": we just compare the URL "&Start=" parameter of current and former page.
For that, we have to remember the URL "&Start=" parameter and put it into a cookie "start".
We also need to save the current page number. We put it into a cookie "page".
At onload event we calculate the current page number based on previous page number:
if "&Start=" parameter is larger now then we add 1
if "&Start=" parameter is smaller now then we subtract 1
if "&Start=" parameter didn't change then we keep the former value
If "&Start=" parameter is empty we know we are on page 1.
Here is one other thing we have to deal with: cookies are saved per user session not per browser tab. That means, if we have two views open in browser same cookies "start" and "page" would be used. To avoid that, we have to add to cookie name something tab specific. I use for that a random four digit number and save it in window.name which is tab specific.
I understand your question that you have a working form $$ViewTemplateDefault and now looking for a possibility to show the current page number "Page nn" in that form.
I assume that you use #DbCommand("Domino"; "ViewNextPage") for getting next page and #DbCommand("Domino"; "ViewPreviousPage") for getting previous page.
Those next and prev functions working the way that always one document will "overlap". If you have 30 lines per page and click next, then last document will be first in next page and next 29 show up in addition. You can watch that in used URL parameter "&Start=": 1 ... 30 ... 59 ... 88 ...
Knowing this you can count the current page number this way:
_start := #ToNumber(#Replace(#UrlQueryString("start"); ""; "1"));
_count := #ToNumber(#Replace(#UrlQueryString("count"); ""; "30")) - 1;
#Integer((#ToNumber(_start) / _count) + 1)
Be aware that this will work for non-categorized and non-collapsible views only.
A more sophisticated solution you can find here. It has additional features like GoTo page and Documents per page.
If you have the chance for your project then use XPages instead. You can do pagination much easier as it is available "out of the box".
Update:
You won't find a reasonable solution for categorized views. If you don't want to use Domino Data/Access Services REST API you have to live with the Domino view URL parameters (look here for "OpenView"). You aren't able to tell from "&Start=" or any other parameter on which page you are currently on.
The easiest way to get a good working pagination is using XPages. Hope you are allowed to use it in your project...
I'm having an issue with CI Active Record's "Where Not In". I am trying to exclude a series of ID's. I couldn't understand why everything worked fine and dandy with one record, but not with multiple.
My Query
$this->db->where_not_in('crm.user_id', $ignore);
The problem is when I profile the the Query is wrong.
With a string of ID's
// $ignore = "12,13";
SELECT *
FROM (`crm`)
WHERE `crm`.`user_id` NOT IN ('16,13')
AND `survey` = 1
With a string of Quotes ID's
// $ignore = "'12','13'";
SELECT *
FROM (`crm`)
WHERE `crm`.`user_id` NOT IN ('\'16\',\'13\'')
AND `survey` = 1
Am I forced to do a loop of "or_where_not_in" or something like that?
where_in and where_not_in expect you to pass an array, not a string as the 2nd parameter.
$ignore = array(12, 13);
$this->db->where_not_in('crm.user_id', $ignore);
