EDIT:
I want to thanks #jimmix for giving me some idea to get started on my last post, But unfortunately, my post was put on hold. Due to the lack of details.
But here are the real scenario, I'm sorry if I didn't explain well my question.
From my CSV file, I have a raw data, then I will upload using my upload() function in into my phpmyadmin database with the table name "tbldumpbio",
See the table structure below:(tbldumpbio)
From my table tbldumpbio data, I have a function called processTimesheet()
Here's the code:
public function processTimesheet(){
$this->load->model('dbquery');
$query = $this->db->query("SELECT * FROM tbldumpbio");
foreach ($query->result() as $row){
$dateTimeExplArr = explode(' ', $row->datetimex);
$dateStr = $dateTimeExplArr[0];
$timeStr = $dateTimeExplArr[1];
if($row->status='C/Out' and !isset($timeStr) || empty($timeStr) ){
$timeStrOut ='';
} else {
$timeStrOut = $dateTimeExplArr[1];
}
if($row->status='C/In' and !isset($timeStr) || empty($timeStr) ){
$timeStrIn ='';
} else {
$timeStrIn = $dateTimeExplArr[1];
}
$data = array(
'ID' => '',
'companyAccessID' => '',
'name' => $row->name,
'empCompID' => $row->empid,
'date' => $dateStr,
'timeIn' => $timeStrIn,
'timeOut' => $timeStrOut,
'status' => '',
'inputType' => ''
);
$this->dbquery->modInsertval('tblempbioupload',$data);
}
}
This function will add another data into another table called "tblempbioupload". But here are the results that I'm getting with:
Please see the below data:(tblempbioupload)
The problem is:
the date should not be duplicated
Time In data should be added if the status is 'C/In'
Time Out data should be added if the status is 'C/Out'
The expected result should be something like this:
The first problem I see is that you have a time expressed as 15:xx:yy PM, which is an ambiguous format, as one can write 15:xx:yy AM and that would not be a valid time.
That said, if what you want is that every time the date changes a row should be written, you should do just that: store the previous date in a variable, then when you move to the next record in the source table, you compare the date with the previous one and if they differ, then you insert the row, otherwise you simply progress reading the next bit of data.
Remember that this approach works only if you're certain that the input rows are in exact order, which means ordered by EmpCompId first and then by date and then by time; if they aren't this procedure doesn't work properly.
I would probably try another approach: if (but this is not clear from your question) only one row per empcompid and date should be present, i would do a grouping query on the source table, finding the minimum entrance time, another one to find the maximum exit date, and use both of them as a source for the insert query.

I'm trying to insert an array of data into a table in database but an error said Array to string conversion error
This is the post function in my controller, first i post an array of data. The values of the array will be the names, and numbers, they are not id. The id is only kodejdwl. This will be pass to my model
function index_post() {
$data = array(
'kodejdwl' => $this->post('kodejdwl'),
'tahun_akad' => $this->post('kode_tahun_akad'),
'semester' => $this->post('semester'),
'mk' => $this->post('mk'),
'ruangan' => $this->post('ruangan'),
'nama_dosen' => $this->post('nama_dosen'),
'namakelas' => $this->post('nama_kelas'),
'jam_mulai' => $this->post('jam_mulai'),
'jam_selesai' => $this->post('jam_selesai'),
);
}
After the data from above code is passed to the model. I created some new variables which are the id of each the name of the value in the array data. e.g if the value of data['mk'] is Website then the id will be 1 and that id will be stored in variable $kodemk and i do it to each value in the data. Then i created new_data which stores array of the id's which i previously made. Then i insert that array into one table in my database. I thought it would be fine but it said Array to string conversion error. What should i do so i could insert that array into the table in my database?
public function insert($data){
$this->db->select('thn_akad_id');
$tahunakad_id = $this->db->get_where('tik.thn_akad',array('tahun_akad'=>$data['tahun_akad'],'semester_semester_nm'=>$data['semester']))->result();
$this->db->flush_cache();
$this->db->select('kodemk');
$kode_mk = $this->db->get_where('tik.matakuliah',array('namamk'=>$data['mk']))->result();
$this->db->flush_cache();
$ruangan = $this->db->get_where('tik.ruangan', array('namaruang' => $data['ruangan']), 1)->result();
$this->db->flush_cache();
$this->db->select('nip');
$nip_dosen = $this->db->get_where('tik.staff',array('nama'=>$data['nama_dosen']))->result();
$this->db->flush_cache();
$this->db->select('kodeklas');
$kodeklas = $this->db->get_where('tik.kelas',array('namaklas'=>$data['namakelas']))->result();
$this->db->flush_cache();
$this->db->select('kode_jam');
$kode_mk = $this->db->get_where('tik.wkt_kuliah',array('jam_mulai'=>$data['jam_mulai'],'jam_selesai'=>$data['jam_selesai']))->result();
$this->db->flush_cache();
$new_data = array(
'kodejdwl' => $data['kodejdwl'],
'thn_akad_thn_akad_id' => $tahunakad_id,
'matakuliah_kodemk' => $kode_mk,
'ruangan_namaruang' => $ruangan,
'staff_nip' => $nip_dosen,
'kelas_kodeklas' => $kodeklas,
);
$insert = $this->db->insert('tik.jadwal_kul', $new_data);
return $this->db->affected_rows();
}
You probably want to use row() instead of result() because it'll contain only one result that you want. If you want to use result() and store multiple values then you'll have to use implode to concatenate them and store it as a string.
I've written a possible solution for your problem; Some things were missing, so I've mentioned them in the comments. See if this helps you.
public function insert($data){
$this->db->select('thn_akad_id');
$tahunakad_id = $this->db->get_where('tik.thn_akad',array('tahun_akad'=>$data['tahun_akad'],'semester_semester_nm'=>$data['semester']))->row(); // use row here
$this->db->flush_cache();
$this->db->select('kodemk');
$kode_mk = $this->db->get_where('tik.matakuliah',array('namamk'=>$data['mk']))->row();
$this->db->flush_cache();
// remove your_ruangan_column with your desired column name
$this->db->select('your_ruangan_column');
$ruangan = $this->db->get_where('tik.ruangan', array('namaruang' => $data['ruangan']), 1)->row();
$this->db->flush_cache();
$this->db->select('nip');
$nip_dosen = $this->db->get_where('tik.staff',array('nama'=>$data['nama_dosen']))->row();
$this->db->flush_cache();
$this->db->select('kodeklas');
$kodeklas = $this->db->get_where('tik.kelas',array('namaklas'=>$data['namakelas']))->row();
$this->db->flush_cache();
// Not sure where this ↓↓ is being used but you can use it the same way as others
$this->db->select('kode_jam');
// duplicate variable name here ↓↓ (fix this)
$kode_mk = $this->db->get_where('tik.wkt_kuliah',array('jam_mulai'=>$data['jam_mulai'],'jam_selesai'=>$data['jam_selesai']))->row();
$this->db->flush_cache();
$new_data = array(
'kodejdwl' => $data['kodejdwl'],
'thn_akad_thn_akad_id' => $tahunakad_id->thn_akad_id, // {$tahunakad_id} consists an object with the key {thn_akad_id}-- table_column_name
'matakuliah_kodemk' => $kode_mk->kodemk, // ...
'ruangan_namaruang' => $ruangan->your_ruangan_column, // ...
'staff_nip' => $nip_dosen->nip, // ...
'kelas_kodeklas' => $kodeklas->kodeklas // ...
);
$insert = $this->db->insert('tik.jadwal_kul', $new_data);
return $this->db->affected_rows();
}
Your are making a total of 7 separate trips to the database. Best practice recommends that you always minimize your trips to the database for best performance. The truth is that your task can be performed in a single trip to the database so long as you set up the correct INSERT query with SELECT subqueries.
I don't know what your non-English words are, so I will use generalized terms in my demo (I've tested this successfully in my own CI project). I am also going to reduce the total subqueries to 3 to reduce the redundance in my snippet.
$value1 = $this->db->select('columnA')->where('cond1', $val1)->get_compiled_select('childTableA');
$value2 = $this->db->select('columnB')->where('cond2', $val2)->get_compiled_select('childTableB');
$value3 = $this->db->select('columnC')->where('cond3', $val3)->get_compiled_select('childTableC');
return (int)$this->$db->query(
"INSERT INTO parentTable
(column1, column2, column1)
VALUES (
($value1),
($value2),
($value3)
)"
);
// to mirror your affected rows return... 1 will be returned on successful insert, or 0 on failure
Granted this isn't using the ActiveRecord technique to form the complete INSERT query, but this is because CI doesn't allow subqueries in the VALUES portion (say, if you were to use the set() method). I am guessing this is because different databases use differing syntax to form these kinds of INSERTs -- I don't know.
The bottom line is, so long as you are fetching a single column value from a single row on each of these sub-SELECTs, this single query will run faster and with far less code bloat than running N number of individual queries. Because all of the variables involved are injected into the sql string using get_compiled_select() the stability/security integrity should be the same.
Below I have stripped down my code to a simplified version. I am storing SQL SELECT results for:
last name (dlname)
category (category)
date this data was added to database (date_added)
clients name (client)
I have appended an additional field outside the SQL SELECT called 'days_on_list'. This field shows the number of days since the data was added to the database, making the table output 5 columns of user data. ALL 5 COLUMNS ARE TO BE SORTABLE.
I am using server-side JSON and have successfully been able to display this to the table and perform sorting on 4 of the 5 columns. The problem is that I am unable to sort the 'days_on_list' field as the PHP file containing the SQL code only allows me to sort the 4 fields from the select query. Is there a way I can make 'days_on_list' column be sortable in the table? I know I can add this field to the sql table, but I would have to run a scheduled event on the server to update this daily (which I am not comfortable with).
Is there another way to allow for this kind of flexible table sorting?
Sorry about the question title (may be confusing), I was having trouble putting this into a question.
/*SQL CODE ABOVE HERE STORES SELECT RETURNS IN $result*/
$cart = array();
$i = 0; //index the entries
// get variables from sql result.
if ($num_rows > 0) { //if table is populated...
while ($row = mysqli_fetch_assoc($result)) {
//calculate days on list by getting the number of days from
//the 'date_added' to today
$date1 = date_create($row['date_added']);
$today = date_create(date("d-m-Y"));
$interval = date_diff($date1, $today);
$doty = $interval - > format("%a");
$cart[$i] = array(
"dlname" => htmlspecialchars($row['dlname']),
"category" => htmlspecialchars($row['category']),
"date_added" => htmlspecialchars($row['date_added']),
"client" => htmlspecialchars($row['client']),
"days_on_list" => $doty, //date_added to now
);
$i = $i + 1; //add next row
}
//encoding the PHP array
$json_server_pagination_data = array(
"total" => intval($num_rows),
"rows" => $cart, //array data
);
}
echo json_encode($json_server_pagination_data);
Because days_on_list is calculated by simply comparing date_added to the current date, sorting by days_on_list should have exactly the reverse effect as sorting by date_added.
In other words, you don't actually need to sort by days_on_list. If the user selects days_on_list as the sort column, just use ORDER BY date_added (in the opposite direction ASC/DESC).
I have trouble saving my date and time values. I tried different formats, here the actual try.
validator in my form:
$datum=$this->CreateElement('text','datum')
->setAttrib('size', '10')
->addValidator(New Zend_Validate_Date('MM-DD-YYYY'));
$zeit=$this->CreateElement('text','zeit')
->setAttrib('size', '10')
->addValidator(new Zend_Validate_Date(array('format' => 'H:i:s')));
Snippet of my Controller addAction
if ($this->getRequest()->isPost()) {
$formData = $this->getRequest()->getPost();
if ($form->isValid($formData)) {
$logenr = $this->_getParam('kopfnr', 0);
$kopfnr = $logenr;
$dat= $form->getValue('datum');
$zeit = $form->getValue('zeit');
$thema = $form->getValue('thema');
$aktermine = new Application_Model_DbTable_Aktermine();
$aktermine->addTermine( $kopfnr, $dat, $zeit, $thema);
And, my add function in my database class:
public function addTermine($kopfnr, $datum, $zeit, $thema)
{
$data = array(
'kopfnr' => $kopfnr,
'datum' => $datum,
'zeit' => $zeit,
'thema' => $thema,
);
$this->insert($data);
}
I´m using a mySQL database on a WAMP installation.
Where is my error? As a remark I want to say, I get a new record, the value of "thema" and the keys are properly saved, so I think it must be some format thing somewhere.
EDIT: I get a new record but the fields date and time are empty. I get no errors
NEW: I added a debug test in my controller to see what comes for the date value, here is the answer:
string '01-04-2016' (length=10)
(I put in 01-04-2016)
By reading your comments I understand you have two problems. The first one is putting the date into your table and the second is to let the user use the normal date format (dd/mm/yyyy).
First problem is solved when you reformat the user input before putting it into the database.You can add the following line into the $form->isValid($formData) part:
$dat = (new DateTime($form->getValue('datum')))->format('Y-m-d');
This oneliner will convert the date from 'dd-mm-yyyy' to 'yyyy-mm-dd'.
thanks, after the suggestion to debug I changed the format of my date like this: $test1=date('Y/m/d',strtotime($dat));
And now it works!
So I am making a quiz in which the user gets confronted with a succession of questions which he answers through a form.
The series of problems each contain a given number of questions, and the questions get asked one after the other when the user validates.
I am therefore trying to re-render the view with the form for each problem until they're all done. This is my action:
public function actionAnswer($id_serie)
{
if ($id_serie != 0) //getting the serie's info
{
$serie = Serie::find()
->where(['id' => $id_serie])
->one();
$problems = (new \yii\db\Query()) //getting the problems in the serie
->select('*')
->from('problems')
->where(['id_serie' => $id_serie])
->all();
$prob_counter = $serie->nbr_of_problems; //counts the number of questions answered
$id_serie = 0;
}
$model = new Answer;
if ($model->load(Yii::$app->request->post()) && $model->validate())
{
$model->save(); // works just fine every time
if (--$prob_counter <= 0)
{
return $this->redirect('index.php?r=student/entry');
}
}
return $this->render('answer',
['model' => $model,
'problems' => $problems,
'serie' => $serie,
'prob_counter' => $prob_counter, //these last two are for debug
'id_serie' => $id_serie]);
}
When this action gets executed the first time, $id_serie is never null or =0. Hence I am using this to query the db only once and set a counter to the total number of problems in the serie. (id est the number of time the user has to submit the form)
If his answer is valid, I decrement my counter and if it falls under 0, there are no questions to answer anymore and the user gets redirected.
However, this counter never goes down to 0: it is set correctly, it is decremented only once, and then it never falls lower, no matter where I put the line. (inside or outside any loop)
On the other hand the data from the form is properly inserted in the db each time.
What am I getting wrong?
As per your code, $prob_counter just stores the number of problems for each series. You need to change this to show the number of unanswered problems for the series. How you implement this will depend on your models and database but it should be something like:
$problems = (new \yii\db\Query()) //getting the problems in the serie
->select('*')
->from('problems')
->where(['id_serie' => $id_serie])
->andWhere('not exists (select id from answer where problemid = problems.id')
->all();
Also you should probably look at working with relational data and avoid using Query() in the above section.
I have 2 dates (create, update) that i want to merge in a new column, selecting the newest date... how can I do it?
Here is the array creation:
$this->Message= array(
'fields' => array('Message.id','Message.type','Message.createdate','Message.updatedate'),
'conditions' => $cond);
$messages = $this->Message->find('all', $conditionsMessage);
Now I need another field (lets call it NewDate) Message.NewDate that gets the newest date from Message.createdate and Message.updatedate, so i can call it after in a view using $messages[NewDate]
Help plz...
Thx!
UPDATE:
It's not hard to loop over the array with something like
foreach($messages as $k => $m){
if(strtotime($m['Message']['updatedate']) > strtotime($m['Message']['createdate'])){
$messages[$k]['Message']['NewDate'] = $m['Message']['updatedate'];
}else{
$messages[$k]['Message']['NewDate'] = $m['Message']['createdate'];
}
}
ORIGINAL ANSWER:
I would think that your Message.updatedate would always be the newest date, so you could just select that. But assuming that's not the case for some reason, you can create a virtual field in your model:
public $virtualFields = array(
'NewDate' => "IF(Message.updatedate > Message.createdate, Message.updatedate, Message.createdate)"
);
This uses the MySQL IF() function. If you're not using MySQL you'd have to figure out how to do something similar with your database.
