I want delete a zip file using codeigniter
This is my controller file:
public function delete($id)
{
$this->db->select('*');
$this->db->from('ag_angel1');
$this->db->where('angel1_id',$id);
$this->db->join('ag_file','ag_file.file_id = ag_angel1.angel1_id','left');
$ag=$this->db->get()->result();
foreach($ag as $g){
$path=realpath('uploaded/angel1/'.$g->file_name);
if (file_exists($path)) {
$this->load->helper('file');
delete_files($path) or die('failed deleting: ' . $path);
}else{
$this->load->helper('file');
unlike($path);
}
}
Code in model:
function delete($id)
{
if(!$id==null){
$this->db->where('angel1_id',$id);
if($this->db->delete('ag_angel1'))
{
return true;
}
}
}
But it doesn't work.
What is wrong?
$this->db->delete is used to delete data from a databse to delete a file use unlink
<?php unlink(server_path_to_your_file);?>
use this code in your model instead
function delete($id)
{
if(!$id==null){
$this->db->where('angel1_id',$id);
if(unlink('path_to_your_file'))
{
return true;
}
}
}

I laravel 9 project with squizlabs/php_codesniffer my phpstorm 2021 shows error :
Expected parameter of type '\TValue', 'Vote' provided
in model when I use table name in scope condition :
class QuizQualityResult extends Model
{
protected $table = 'quiz_quality_results';
public function scopeGetByVoteCategories($query, $voteCategoryId= null)
{
// “new Vote” is marked as error
$voteTable = with(new Vote)->getTable();
if (!empty($voteCategoryId)) {
if ( is_array($voteCategoryId) ) {
$query->whereIn( $voteTable . '.vote_category_id', $voteCategoryId);
} else {
$query->where( $voteTable . ' . vote_category_id', $voteCategoryId);
}
}
return $query;
}
If there is a way to fix this error ? Or maybe to use better syntax here ?
Thanks!
There is no need for helper with() here
$voteTable = (new Vote())->getTable()
Ps: there is a feeling that your method does not work the way you intended. Perhaps you meant to do the following (I could be wrong):
public function scopeGetByVoteCategories($query, $voteCategoryId = null)
{
if (empty($voteCategoryId)) {
return $query;
}
return $query->whereHas('vote', static function ($query) use ($voteCategoryId) {
if (is_array($voteCategoryId)) {
return $query->whereIn('vote_category_id', $voteCategoryId);
}
return $query->where('vote_category_id', $voteCategoryId);
});
}
public function vote()
{
// your relationship
}
I have this error when i trying to delete an image from db:
Undefined variable: removeslider
public function delete($id){
$getslider = DB::table('slider')->where('id',$id)->get();
foreach($getslider as $getslider) {
$removeslider = $getslider->bgimage;
}
Storage::disk('uploadssliders')->delete($removeslider);
return redirect('admin/inicio');
}
Try this:
public function delete($id)
{
$getslider = DB::table('slider')->where('id',$id)->first();
if($getslider){
Storage::disk('uploadssliders')->delete($getslider->bgimage);
return redirect('admin/inicio');
} else {
//id has no match in the database
echo "the id ". $id . " does not exist";
}
}
I changed your get() to first() to only get one result as this seems what you are trying to do then the foreach is not needed.
I update two data one text data and two file data but it's not working this. How to update file?
My code is:
public function update(Request $request){
$news=new News();
$news->newstitle=$request->newstitle;
$url1=$this->imageExistStatus1($request);
$news->save();
return redirect()->back()->with('sms','insert successful');
}
public function imageExistStatus1($request){
$newsByid1=News::where('id',$request->newsid)->first();
$fimage1=$request->file('imageone');
if ($fimage1) {
unlink($newsByid1->imageone)
$thisName1= $fimage1->getClientOriginalName();
$uplodePath1='public/up/';
$fimage1->move($uplodePath1,$thisName1);
$url1=$uplodePath1.$thisName1;
}else{
$url1=$newsByid1->imageone;
}
return $url1;
}
First, change your code to the following
public function update(Request $request, $id)
{
$news = News::findOrFail($id);
$news->newstitle = $request->newstitle;
$fimage1 = $request->file('imageone');
if ($fimage1) {
unlink($news->imageone);
$news->imageone = $this->imageExistStatus1($request, $id);
}
$news->save();
return redirect()->back()->with('sms', 'insert successful');
}
public function imageExistStatus1($request)
{
$fimage1 = $request->file('imageone');
$thisName1 = $fimage1->getClientOriginalName();
$uplodePath1 = 'public/up/';
$fimage1->move($uplodePath1, $thisName1);
$url1 = $uplodePath1 . $thisName1;
return $url1;
}
I hope your problem is resolved
tip:
Thanks to "Oluwatobi Samuel Omisakin".
please use the route:
Route::patch('/news/{id}/update', 'NewsController#update')
As JsHelper is no more in cakephp 3.0 so what i am doing is to save my form data into database using ajax
i just have two input fields.
my files are:
add.ctp
js.js
EmployeesController.php
add.ctp
$this->Form->create('Employees');
$this->Form->input('name', array('id'=>'name'));
$this->Form->input('age', array('id'=>'age'));
$this->Form->button('Add Info', array(
'type'=>'button',
'onclick'=>'infoAdd();'
));
$this->Form->end();
js.js
function infoAdd() {
var name=$("#name").val();
var age=$("#age").val();
$.get('/employees/info?name='+name+"&age="+age, function(d) {
alert(d);
});
}
EmployeesController.php
class EmployeesController extends AppController {
public $components=array('RequestHandler');
public function add() {
$emp=$this->Employees->newEntity();
if($this->request->is('ajax')) {
$this->autoRender=false;
$this->request->data['name']=$this->request->query['name'];
$this->request->data['age']=$this->request->query['age'];
$emp=$this->Employees->patchEntity($emp,$this->request->data);
if($result=$this->Employees->save($emp)) {
echo "Success: data saved";
//echo $result->id;
}
else {
echo "Error: some error";
//print_r($emp);
}
}
}
}
Note : my model only have not empty rule for both fields
all what i am doing is working fine but i dont think i m doing it in right way or as it should be.
please help me what i m missing and what i don't need to do.
Take away the autoRender line and serialize the data you want returned:
public function add() {
$data = [];
$emp=$this->Employees->newEntity();
if($this->request->is('ajax')) {
$this->request->data['name']=$this->request->query['name'];
$this->request->data['age']=$this->request->query['age'];
$emp=$this->Employees->patchEntity($emp,$this->request->data);
if($result=$this->Employees->save($emp)) {
$data['response'] = "Success: data saved";
//echo $result->id;
}
else {
$data['response'] = "Error: some error";
//print_r($emp);
}
}
$this->set(compact('data'));
$this->set('_serialize', 'data');
}
The serialize function tells Cake that it's not expecting the function to have a view, so autoRender is not needed (http://book.cakephp.org/3.0/en/views/json-and-xml-views.html).
I am new in Grocery Crud with Code Igniter and need a help. I have table vaboteni (emploees) and it work well. But I get stuck with code add more action. When I click to add action button I got error 404 Page Not Found. I want to fetch "id" from one row in table and pass to another view in order to display data for only one employee. I have site in local server, address localhost/bis_resursi/index.php/vraboteni/vraboteni_managment
Here is my Controller vraboteni.php
function vraboteni_management()
{
$crud = new grocery_CRUD();
$crud->set_theme('datatables');
$crud->set_table('vraboteni');
$crud->set_subject('вработен');
.....
$crud->add_action('Преглед', '', 'vraboteni/vraboten_managment/pregled','ui-icon-plus');
function pregled($id)
{
$this->load->model("vraboteni_pregled_model");
$data["result"] = $this->getVraboteniPregled($vrabotenID);
$this->load->view("pregled", $data);
}
$output = $crud->render();
$this->_example_output($output);
}
and Models: vraboteni_pregled_model.php
<?php
class Vraboteni_Pregled_Model extends CI_Model {
function __construct()
{
parent::__construct();
}
}
function getVraboteniPregled($id){
$query = $this->db->query("SELECT * FROM vraboteni WHERE vraboteID = '$id' ");
return $query->result();
}
and in view vraboten_view.php I put
<?=$query['vrabotenID']?>
<br>
Hi, I'am <?=$query['ime']?>
<br>
from<?=$query['adresa']?>
I managed to find solution. Right code is:
Controller vraboteni.php
$crud->add_action('Преглед', '', 'vraboteni/get','ui-icon-plus');
$output = $crud->render();
$this->_example_output($output);
}
function vraboteni()
{
$crud = new grocery_crud();
$crud->set_table('vraboteni');
$output = $crud->render();
print_r($output);
}
function getall()
{
$this->load->model('vraboten_model');
$data['query']=$this->vraboten_model->vraboten_getall();
$this->load->view('vraboten_view',$data);
}
function get($vrabotenID)
{
$this->load->model('vraboten_model');
$data['query']=$this->vraboten_model->vraboten_get($vrabotenID);
$this->load->view('vraboten_view',$data);
}
Models vraboten_model.php
<?php
class Vraboten_model extends CI_Model{
function vraboten_model(){
parent::__Construct();
}
function vraboten_getall(){
$this->load->database();
$query=$this->db->get(' vraboteni');
return $query->result();
}
function vraboten_get($vrabotenID){
$this->load->database();
$query=$this->db->get_where(' vraboteni',array('vrabotenID'=>$vrabotenID));
return $query->row_array();
}
}
and view vraboten_view.php
<?=$query['vrabotenID']?>
<br>
Hi, I'am <?=$query['ime']?>
<br>
from<?=$query['adresa']?>
