I have a loop in my php which takes the database values of two tables and displays them in a CodeIgniter dropdown - however the array doesn't reset itself after the news_types loop, it uses the category data instead...can anyone help me?
Thanks
//inside a loop
if(isset($news_types)) {
foreach($news_types as $type) {
$options[$type['id']] = ucwords($type['type']);
}
}
if(isset($categories)) {
foreach($categories as $category) {
$options[$category['id']] = ucwords($category['category']);
}
}
echo '<p>';
echo format_label($field);
echo form_dropdown($field, $options, check_value($field, $submitted, $record->$field));
echo '</p>';
If your news type id's match up with category ids they will be overwritten... Try this to verify
if(isset($news_types)) {
foreach($news_types as $type) {
$options["news_".$type['id']] = ucwords($type['type']);
}
}
if(isset($categories)) {
foreach($categories as $category) {
$options["cat_".$category['id']] = ucwords($category['category']);
}
}
prefix your ids to make sure they do not clash.

i use laravel:command for function, which is i need to know how many reviews been given to my products, i will capture my database example below:
Product fields
Reviews fields
i've already declare the relationship which is:
App\Models\Product :
public function rev()
{
return $this->hasMany(Reviews::class, 'product_id', 'id');
}
App\Models\Review :
public function prod()
{
return $this->belongsTo(Products::class, 'product_id','id');
}
and this is my command for the function:
protected $signature = 'review:product {product_id}';
public function handle()
{
$id = $this->arguments('product_id');
$products = Products::with('rev')->whereId($id)->get();
foreach ($products as $key => $value) {
$rating = $value->rev->rating;
}
dd($products);
}
after i run my command it returns this error
Error
what i'm expecting is i could get the whole rating of specific id
You did not declare the variable $rating prior to using it.
But there is a much easier approach to your problem, since youve already setup the relationships.
public function handle()
{
$id = $this->arguments('product_id');
$products = Products::find($id);
$ratings = $products->rev->pluck('rating');
dd($ratings);
}
Because of product can have many revs, so you can use loop for this
foreach ($value->rev as $item) {
$val = $item->rating;
}
if you are expecting to sum up all rating for particular product id, then you should declare initial number for variable $rating before foreach, then sum up with += operator :
public function handle(){
$id = $this->arguments('product_id');
$products = Products::with('rev')->whereId($id)->get();
$rating = 0;
foreach ($products as $key => $value) {
$rating += $value->rev->rating;
}
dd($rating);
}
I have created a model which joins 2 tables
function list_get($id){
$this->load->database();
$query = $this->db-> select('*')
->from('lists')
->join('list_items', 'list_items.items_list_id = lists.list_id')
->where('items_list_id', $id);
return $query->get()->row_array();
}
In my controller I created the view_list function
public function view_list($id = !FALSE){
$this->load->model('model_lists');
$data["query"] = $this->model_lists->list_get($id);
$this->load->model('model_lists');
if($data["query"]){
$this->load->view('lists/view_list',$data);
} else {
redirect('lists');
}
}
Now my view returns only the first result from the database
<?php echo $query['item_url'];?> How can I create a foreach to show all the results?
change this line return $query->get()->row_array();
to return $query->get()->result_array();
in view
foreach($query as $querys){
echo $querys['item_url'];
echo '</br>';
}
Change this return $query->get()->row_array(); to this
return $query->result_array();
and in view
foreach($query as $row)
{
echo $row['column_name'];
}
In this codeigniter model i have this query testing if value entered in input exists in database..
function get_search_form() {
$match = $this->input->post('search1');
$this->db->where('numero',$match);
$this->db->where('inscris','non');
$q = $this->db->get('transaction');
if($q->num_rows()>0)
{
foreach($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
Behold the controller i'd like to display value grabbed in input in view inscription.php
function search()
{
$data['row'] = $this->site_model->get_search_form();
$this->load->view('acceuil/aside');
$this->load->view('acceuil/inscription', $data);
}
My issue is how to display in that view input value and a form if this value exists in database ?
I have tried like this but i need help :
inscription view:
<?=form_open('navigation/search');?>
<input type="text" name="search1" id="search1" required />
<input type='submit' value='Display' />
<?=form_close();?>
I try to display the form like this but i don't know how to display as well the input value entered
<?php
if( $row > 0 )
{
?>
les champs du formulaire ici....
<?php
}else
{ }
?>
In your view you can check if the variable $row is not null (because it will be null when no rows are found):
if ($row !== null) {
// do stuff
}
You can modify the model function to return some other value if no rows are found, for example, by setting the $data to an empty array:
function get_search_form() {
$match = $this->input->post('search1');
$this->db->where('numero',$match);
$this->db->where('inscris','non');
$q = $this->db->get('transaction');
$data = array(); // <--- here
if($q->num_rows()>0)
{
foreach($q->result() as $row)
{
$data[] = $row;
}
return $data;
}
}
And then in the view you can simply loop the data:
foreach($row as $r) {
// do stuff
}
or you can implode the array to use as the input value:
<input type="text"
name="search1"
id="search1" required
value="<?php echo implode(' ', $row); ?>" />
You could also use html entities here, in case double quotes are possible to appear in what your model function returns (I have no idea what it returns).
you can access $data global object like this check
<?php
if( isset($row))
{
foreach($row as $v){
//Do the operations here
}
}else
{
//Do the operations here
}
?>
I already sort the products in every category in the Admin Panel. It doesn't work accordingly in the Frontend but in the Homepage everything is fine. I checked on this link and I want to know how to make it enforce sorting by position STACK QUE
I'm also referring to the same list.phtml in Grid view. Can anyone help me? Thank you!
Just in case someone bump into the same error. Here is the solution I managed to make it work. First you need to copy the Toolbar.php from the mage core and paste it in the local mage pool and find the the function setCollection and replace it with the following code:
public function setCollection($collection)
{
$this->_collection = $collection;
$this->_collection->setCurPage($this->getCurrentPage());
// we need to set pagination only if passed value integer and more that 0
$limit = (int)$this->getLimit();
if ($limit) {
$this->_collection->setPageSize($limit);
}
if ($this->getCurrentOrder()) {
if(($this->getCurrentOrder())=='position'){
$this->_collection->setOrder('position','asc');
}
else {
$this->_collection->setOrder($this->getCurrentOrder(),$this->getCurrentDirection());
}
}
return $this;
}
To create sort by position write below code after getting product collection in app/design/frontend//default/template/catalog/product/list.phtml
$_productCollection = new Varien_Data_Collection();
$sortedCollection = array();
foreach ($_defaultProductCollection as $key => $_product) {
if(!isset($sortedCollection[$positions[$_product->getId()]])){
$sortedCollection[$positions[$_product->getId()]] = array();
}
$sortedCollection[$positions[$_product->getId()]][] = $_product;
}
ksort($sortedCollection);
foreach ($sortedCollection as $_products) {
foreach ($_products as $_product) {
$_productCollection->addItem($_product);
}
}
Hope it will work for you.
I a have a dropdown list which is being populated from database. It is working fine but in the view file I want the dropdown list to show "SELECT" on the very top of all values. Would you please kindly help me with this?
Thanks in Advance
I have this in my controller
// To get the batch name
$this->load->model('dropdown_batchlist');
$data['dropdown_batchlist']= $this->dropdown_batchlist->dropdown_batchlist();
this in my model-
function dropdown_batchlist() {
$this->db->select('batchname, batchid');
$records=$this->db->get('batch');
$data=array();
foreach ($records->result() as $row)
{
$data[$row->batchid] = $row->batchname;
}
return ($data);
}
And this in my view file
<?php echo form_dropdown('batchid', $dropdown_batchlist ); ?>
You just have to add the 'SELECT' as the first item in the array:
function dropdown_batchlist() {
$this->db->select('batchname, batchid');
$records=$this->db->get('batch');
$data=array();
// add it here as the first item in the array,
// assuming you don't have a $row->batchid of 0 in your results.
$data[0] = 'SELECT';
foreach ($records->result() as $row)
{
$data[$row->batchid] = $row->batchname;
}
return ($data);
}
