I want to pass an array in codeigniter query. Below is my code.
Controller
foreach($array as $values) {
$array_values = $values['download_subcategory_name'];
}
$this->data['get_downloads_content'] = $this->my_model->get_downloads_content($array_values );
Model
public function get_downloads_content($array_values ){
$this->db->select('*');
$this->db->from('my_table');
$this->db->where_in('download_subcategory_name', $array_values );
$this->db->order_by('download_id', 'ASC');
$query = $this->db->get();
return $query->result();
}
My problem is query showing results for only last value of array instead of all array values.
Please help.
Just need little changes within foreach
$array_values = array();
foreach($array as $values) {
$array_values[] = $values['download_subcategory_name'];
^^^
}
OR
$array_values = array();
foreach($array as $key => $values) {
$array_values[$key] = $values['download_subcategory_name'];
^^^^^^
}
Within your code it's storing only the last value from the foreach loop thats why it only gets the single value stored within it.

I want to make a query that results like this in codeigniter MODEL:
$caldata = array (
15 => 'yes',
17 => 'no'
);
Is that possible to do?
Take NOTE: The 15,17 and yes,no are in the same database table.
There is no core helper function to achieve what you want in CI. But you can create your own helper function:
function pluck($arr = [], $val = '', $key = '')
{
// val - label for value in array
// key - label for key in array
$result = [];
foreach ($arr as $value) {
if(!empty($key)){
$result[$value[$key]] = $value[$val];
}else{
$result[] = $value[$val];
}
}
return $result;
}
you can use result_array() function so you can have something like:
$query = $this->db->select('id,answer')->from('users')->get();
$result = $query->result_array();
print_r($result);
After that you have your array and you can make the $key => $value relation of the fields
After a long search i found an answer. Sample way to do this:
$query = $this->db->select('start_date, class')->from('event')->like('start_date', "$year-$month", 'after')->get();
$datavariable = $query->result();
$caldata = array();
foreach($datavariable as $row){
$caldata[substr($row->start_date,8,2)] = $row->class;
}
so i have this function
public function GetNearAirport($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);
}
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'm trying to get my head around grabbing all variable I need in Codeigniter and then passing those values to the view.
I understand the concept, but am getting stuck on iterating through an array and adding on another array to each of its keys.
The $data['items'] array contains data passed from a model via the get_all() function. The query is basically "Select * from items".
Each item has multiple features and pictures. In order to get the appropriate values I need the id of an item. I can grab this from the first array ($data['items']) which I can then pass to a model function.
I keep getting various errors when trying to do this via the code below. I've tried defining the features and pictures arrays before the foreach loop - still get errors.
I'm sure my syntax is just wrong. Any help is welcome.
$data['items'] = $this->amazon->get_all();
foreach ($data['items'] as $data )
$id = $data->id;
$data['features'] = $this->amazon->get_features($id);
$data['pictures'] = $this->amazon->get_pictures($id);
}
Edit
Based on feedback I've updated the code to this (lines 24 - 30 of the code):
$items = $this->amazon->get_all();
for($i=0; $i<count($items);$i++) {
$data = $items[$i];
$id = $data->id;
$items[$i]['features'] = $this->amazon->get_features($id);
$items[$i]['pictures'] = $this->amazon->get_pictures($id);
}
PHP is complaining with this:
PHP Fatal error: Cannot use object of type stdClass as array in /var/www/ci/application/controllers/main.php on line 28
Here are the functions from the amazon model:
function get_all()
{
$query = $this->db->get('items');
return $query->result();
}
function get_pictures($id) {
$query = $this->db->query("SELECT link FROM pictures WHERE item_id='$id' AND type IN('thumb_set')");
$style = "border-style:solid; border-width:1px";
$class = "modal-thumb";
$results = '';
foreach ($query->result() as $row) {
$results .= "<li style='$style' class='$class'><img src='$row->link' alt=''/></li>";
}
return $results;
}
function get_features($id) {
$query = $this->db->query("SELECT content FROM features WHERE item_id='$id' ORDER BY feature_num DESC");
$results = '';
foreach ($query->result() as $row) {
$results .= "<li>";
$results .= $row->content;
$results .= "</li>";
}
return $results;
}
I'm thinking i need to use 'results_array()' instead of 'results()'? Are my results returned as an object instead of an array the way things are now?
As you said, you have syntax error in the foreach statement, you are redefining the $data array.
foreach ($data['items'] as $data )
Try this:
$items = $this->amazon->get_all();
for($i=0; $i<count($items);$i++){
$data = $items[$i];
$id = $data->id;
$items[$i]['features'] = $this->amazon->get_features($id);
$items[$i]['pictures'] = $this->amazon->get_pictures($id);
}
function dp(){
$this->load->library('heart');
$times = 35;
$i = 0; while ($i<$times){
$this->heart->test();
//10 newest
$query = $this->db->get('test', 10, 20);
//set variables from query
foreach ($query->result() as $getrow)
{
$data1 = $getrow->data1;
$data2 = $getrow->data2;
}
//for each data1; do go();
foreach ($data1 as $id){
$this->heart->go($id,$data2);
}
//increment $i
$i++;
}
}
Hey guys, here is my code. I am trying to get the most newest entries from the database, then setting them as variables. For each variable, I am trying to call a function to it passing $id (data1) and $data2. Will data2 be passed or do I need to do something like $data1 as $id && $data2 as $id2. I need to pass over $data1 and $data2 to go() which should be different everytime.
The problem here is I keep getting 'Invalid argument supplied for foreach()' whenever I try to run the code. Anyone know what the issue is here?
Thank you in advance.
I believe you actually want to be creating arrays of $data1 and $data2.
Currently you are overwriting the values in each of those variable each time through the first foreach loop.
$data1 = array();
$data2 = array();
//set variables from query
foreach ($query->result() as $getrow)
{
$data1[] = $getrow->data1;
$data2[] = $getrow->data2;
}
//for each data1; do go();
foreach ($data1 as $key => $id){
$this->heart->go($id,$data2[$key]);
}
Alternatively you could use data1 and data2 as the key/value pair of the array
$data = array();
foreach ($query->result() as $getrow)
{
$data[$getrow->data1] = $getrow->data2;
}
//for each data1; do go();
foreach ($data as $key => $value){
$this->heart->go($key, $value);
}
You can do it all with a single foreach loop without building unnecessary data arrays:
foreach($query->result() as $getrow) {
$this->heart->go($getrow->data1, $getrow->data2);
}
