I have the following query:
$this->db->where('user_id', $this->session->userdata('user_id'));
$this->db->where('barcode != ""');
$codes = $this->db->get('acquisti')->result();
return $codes;
This produces a result (varius fields) that can show one or more records, I need to tell Codeigniter to show FROM ANOTHER TABLE the results where "barcode" is one of the record found above.
I tried this:
$this->db->where('user_id', $this->session->userdata('user_id'));
$this->db->where('barcode != ""');
$codes = $this->db->get('acquisti')->result();
foreach ($codes as $key => $value) {
$this->db->where('IRSC', $value->barcode);
return $this->db->get('rendiconti_agosto')->result();
}
But this returns only ONE result even if the $code is actually more than one.
Any hint?
Try to catch them in array and then return them like
foreach ($codes as $key => $value) {
$this->db->where('IRSC', $value->barcode);
$result_arr[] = $this->db->get('rendiconti_agosto')->result();
}
return $result_arr;
In your code you are return for the first time of loop so the loop will terminated at first and then results only the first result that you get.
Try this. You can do it without loop.
$this->db->select("*");
$this->db->from("acquisti a");
$this->db->join("rendiconti_agosto ra","ra.IRSC = a.barcode ");
$this->db->where('a.user_id', $this->session->userdata('user_id'));
$this->db->where('a.barcode <> ""');
$res = $this->db->get();
return $res->result_array();

Need to bind Page drop-down conditionally on base of 'Content' table. Page titles are stored in an associative array and 'Content' table have page code stored in it. Here is the code
Function which return page titles
public function getPageTitles(){
$pageTitles = array("Home"=> "Home",
"AboutUs"=> "About Us", //AboutUs will save in database as pageCode
"Features"=> "Features",
"ContactUs"=> "Contact Us");
return $pageTitles;
}
Function which checks if page have content or not:
public function getPageTitlesWithNoContent()
{
$pageTitles = $this->getPageTitles();
$this->db->distinct('pageCode');
$this->db->select('pageCode');
$this->db->from('content');
$this->db->where('status', 1);
$data = $this->db->get();
$queryResult = $data ? $data->result_array() : 0 ;
$emptyPageTitle = array();
foreach($pageTitles as $x => $x_value)
{
$hasContent = in_array($x, $queryResult);
if (!$hasContent){
$emptyPageTitle[$x] = $x_value;
}
}
return $emptyPageTitle;
}
This function is returning all page titles.. new to php no idea what is wrong
Check name fields in table is same? With Uppercase first char?
Also change your code in this loop:
foreach($pageTitles as $x => $x_value)
{
if (in_array($x, $queryResult)){
$emptyPageTitle[$x] = $x_value;
}
}
I remove ! negative in check condition
#NMathur I think you almost got it. Made some changes for you in that code, Check it.
public function getPageTitlesWithNoContent() {
$pageTitles = $this->getPageTitles();
$this->db->select('pageCode');
$this->db->from('content');
$this->db->where('status', 1);
$this->db->group_by('pageCode');
$query = $this->db->get();
$queryResult = array();
foreach ($query->result_array() as $row) { // This loop should need to form an array based on query result
$queryResult[$row['pageCode']] = $row['pageCode'];
}
$emptyPageTitle = array_diff_key($pageTitles,$queryResult); // Compares the keys from array1 against the keys from array2 and returns the difference
return $emptyPageTitle;
}
As #TamilvananN guided, I printed the queryResult and tried this workaround:
foreach($pageTitles as $x => $x_value)
{
foreach ($queryResult as $item)
{
if (!($x == $item['pageCode'])){
$emptyPageTitle[$x] = $x_value;
}
}
}
It is working, but as you can see this has loop in a loop .. that can be very costly .. can you please share any fast way to compare the results.
so i have this function
public function GetNearAirport($adr)
{
$acftrange = $this->GetAcftAdr($adr);
$too = array();
foreach ($acftrange as $key) {
$result = $this->GetNearRange($adr,$key->range);
}
The $acftrange give me some rows, and i need to get a new result for each row of $acftrange. But i need all results in one array So I can insert into the html table. Sorry for my english. In foreach the $key->range is a condition for the query to be made.
I assume getNearRange() returns an array. Use array_merge to append $result to $too
foreach ($acftrange as $key) {
$result = $this->GetNearRange($adr,$key->range);
$too = array_merge($too, $result);
}
I want to know how to compare these 2 outputs http://prntscr.com/bx7ay9 and return the highest value in the array ?
MY MODEL CODES
$this->db->select('additional');
$this->db->from('order_detail');
$this->db->where('order_id',$id);
$query = $this->db->get();
foreach ($query->result() as $row)
{
$return[] = $row->additional;
}
return $return;
Just use select_max in query to get highest value and use row() to fetch single row without using foreach loop as
$this->db->select_max('additional AS max_value');
$this->db->from('order_detail');
$this->db->where('order_id', $id);
$query = $this->db->get();
$ret = $query->row();
return $ret->max_value;
$this->db->select('additional');
$this->db->from('order_detail');
$this->db->where('order_id',$id);
$query = $this->db->get();
foreach ($query->result() as $row)
{
$return[] = max($row->additional);
}
return $return;
Just used select_max of Codeigniter Query Bulder Class.
Model,
public function get_max ($id){
$this->db->select_max('additional');
$this->db->where('order_id',$id);
$query = $this->db->get('order_detail');
return $query->row();
}
In Controller,
$max = $this->Model->get_max($id);
echo $max['additional']; // Display and see the value.
If you want to get the max number then use select_max(),
$this->db->select_max('additional');
$this->db->from('order_detail');
$this->db->where('order_id',$id);
$query = $this->db->get();
if($query->num_rows()){// check if data is not empty
return $query->row()->additional;
}
return false;// you can return false here
And if you want to get the result array for another use then, you can use max() with $this->db->select('additional'); with your code to get the max number in array.
Simple question to which I don't have an answer.
How can I change my array from this:
[{"sku":"6"},{"buyers":"7"},{"base":"8"}]
to this:
[{"sku":"6","buyers":"7","base":"8"}]
I have three queries for three different database tables:
$sku = DB::table('mapiranje')->select(DB::raw('count(*) as sku'))
->where('mate_fk', '=', NULL)
->get();
$kupac = DB::table('mapkupci')->select(DB::raw('count(*) as buyers'))
->where('kupci_fk', '=', NULL)
->get();
$base = DB::table('dist_base')->select(DB::raw('count(*) as base'))
->where('base_fk', '=', NULL)
->get();
now each returns:
[{"sku":"6"}]
[{"buyers":"6"}]
[{"base":"6"}]
I have used merge_array to make a single array, but I get:
[{"sku":"6"},{"buyers":"7"},{"base":"8"}]
what I want is:
[{"sku":"6","buyers":"7", "base":"8"}]
Refactor your code according to right Laravel way:
$result = [
'sku' => DB::table('mapiranje')->whereNull('mate_fk')->count(),
'buyers' => DB::table('mapkupci')->whereNull('kupci_fk')->count(),
'base' => DB::table('dist_base')->whereNull('base_fk')->count()
];
$result = [];
foreach($input as $oneInputRow) {
$result[$oneInputRow[0]] = $oneInputRow[1];
}
$target = array();
$start = array(array("sku"=>"6"), "buyers"=>"7"), "base"=>"8"));
foreach($start as $sub){
foreach($sub as $key => $val){
$target[$key] = $val;
}
}
Not shure if laravel provides any special syntax, but just with php I'd do it as above.
Basicly you loop over the start-array. In that you loop over every array to get the key/val combination and put that into the target-array.
For the second loop there would be other ways if you only have one entry in every secondary array.
Please try below code
$dd = '[{"sku":"6"},{"buyers":"7"},{"base":"8"}]';
$data = json_decode($dd,true);
$result = array();
foreach($data as $key=>$value){
foreach($value as $key1=>$value1){
$result[$key1] = $value1;
}
}
echo json_encode($result); //this will print your required format result
I got this problem trying to echo out a big array.
print_r looks like this:
http://codepaste.net/5js97a
There's no problem echoing out the first 2 rows like this in a foreach loop:
$item['name'], but for the rest of them deeper inside the array, I just get an error.
Thanks!
Code:
function categories($parent = NULL) {
$query = $this->db->where('parent_id', $parent)->get('categories');
$results = $query->result_array();
foreach($results as $result) {
$child_array = Forummodel::categories($result['id']);
if(sizeof($child_array) == 0) {
array_push($results, $result['name']);
} else {
array_push($results, array($result['name'], $child_array));
}
}
return $results;
}
Im also using codeigniter
You are iterating on an increasing array. Here is your code:
function categories($parent = NULL) {
$query = $this ->db ->where('parent_id', $parent) ->get('categories');
$results = $query->result_array();
foreach($results as $result) {
$child_array = Forummodel::categories($result['id']);
if(sizeof($child_array) == 0) {
array_push($results, $result['name']);
} else {
array_push($results, array($result['name'], $child_array));
}
}
return $results;
}
The foreach is iterating down the array $results and you are adding to it with each loop, plus, by the time you hit an iteration where $result doesn't contain 'id' or 'name' you are probably getting the error. You might want to put the child arrays into another array and merge them after the foreach loop if you still want to do that.
