I'm studing Laravel CRUD.
Laravel Framework is 6.18.15
I would like to select of a record and update.
This is photo gallery.
Now if I click one of photo I can get below URL
https://mywebsite.net/public/edit?id=59
but in edit.blade.php I got this error
Undefined variable: id
Could someone teach me correct code please?
These are current code
Controller UPDATED
public function edit(Request $request)
{
$images = ImageGallery::find($id);
return view('edit',compact('images'));
}
public function editpcs(Request $request)
{
$this->validate($request, [
'title' => 'required',
'image' => 'required|mimes:jpeg,jpg'
]);
$input['image'] = time().'.'.$request->image->getClientOriginalExtension();
if($request->hasFile('image')) {
$image = $request->file('image');
$filename = time().'.'.$request->image->getClientOriginalExtension();
$image_resize = Image::make($image->getRealPath());
$image_resize->resize(1280, null, function ($image) {$image->aspectRatio();});
$image_resize->save(public_path('images/ServiceImages/' .$filename));
}
$request->image->move(public_path('images'), $input['image']);
$input['title'] = $request->title;
// ImageGallery::update($input);
$update = DB::table('image_gallery')->where('id', $id)->update( [ 'title' => $request->title, 'image' => $request->image]);
return view('edit',compact('images'))->with('sucess','sucessfully updated');
}
web.php
//edit view
Route::get('edit', 'ImageGalleryController#edit');
Route::post('edit', 'ImageGalleryController#edit');
//edit procces
Route::get('editpcs', 'ImageGalleryController#editpcs');
Route::post('editpcs', 'ImageGalleryController#editpcs');
UPDATE
#if($images->count())
#foreach($images as $image)
<div class='text-center'>
<small class='text-muted'>{{$image['id']}}/ {{$image['title']}} </small>
</div>
#endforeach
#endif
MODEL
namespace App;
use Illuminate\Database\Eloquent\Model;
class ImageGallery extends Model
{
protected $table = 'image_gallery';
protected $fillable = ['title', 'image'];
}
Actually $id is really undefined here, it would be $request->route('id') or request('id') or $_GET['id'] or $request->input('id') :
public function edit(Request $request)
{
$id = request('id');
$images = ImageGallery::findOrFail($id); // use findOrFail() id not exist in table, it throw a 404 error
return view('edit',compact('images'));
}
Take a look at the $_GET and $_REQUEST superglobals. Something like the following would work for your example:
$id = $_GET['id'];
$country = $_GET['country'];
In laravel you can to use Input::get(), But Input::get is deprecated in newer version of laravel, prefer the $request->input instead of Input::get :
$id= $request->input('id');
$country= $request->input('country');
It looks to me like this function:
public function edit(Request $request)
{
$images = ImageGallery::find($id);
return view('edit',compact('images'));
}
Should be something like this perhaps?
public function edit(Request $request)
{
$id = $request->input('id', null);
$images = ImageGallery::find($id);
return view('edit',compact('images'));
}
As it is, $id appears to be undefined before you attempt to pass it into the find() method. But according to your URL it is in the $request object. So you need to get it from there and into the function. You can read about this method in the docs.
public function edit(Request $request)
{
$id = request('id');
$images = ImageGallery::where('id',$id)->first();
return view('edit',compact('images'));
}
I use the same view to show one post and random post
routes
Route::get('posts/{id}', 'PostsController#show')->name('posts.show');
Route::get('get-random-post', 'PostsController#getRandomPost');
methods in PostsController
public function show($id) {
$post = Post::findOrFail($id);
return view('posts.show', compact('post'));
}
public function getRandomPost() {
$post = Post::inRandomOrder()
->where('is_published', 1)->first();
return redirect()->route('posts.show', ["id" => $post->id]);
}
but now I need to add a small difference between two views. How can I do that?
UPD
I added variable $randomPost to methods in Controller
public function show($id) {
$randomPost = false;
$post = Post::findOrFail($id);
return view('posts.show', compact('post', 'randomPost'));
}
public function getRandomPost() {
$randomPost = true;
$post = Post::inRandomOrder()
->where('is_published', 1)->first();
return redirect()->route('posts.show', ["id" => $post->id]);
}
and added code below to show view
#if($randomPost)
some text
#endif
but I don't know how to pass variable from getRandomPost() to view?
UPD2
As result I used session, it works but I'm not sure about it
method
public function getRandomPost() {
$post = Post::inRandomOrder()
->where('is_published', 1)->first();
session()->flash('random_post', 'ok');
return redirect()->route('posts.show', ["id" => $post->id]);
}
view
#extends('layouts.app')
#section('content')
Home page
<h2>#{{$post->id}}</h2>
{!! nl2br(e($post->text)) !!}
<?php if(session()->has('random_post')){
echo '<div style="text-align: center">';
echo link_to_action('PostsController#getRandomPost', 'Random Post', $parameters = array(), $attributes = array());
echo '</div>';
}?>
#stop
You can use session flash, it lasts only on subsequent request:
// set
session()->flash('random_post', 'ok');
// check
if(session()->has('random_post')){
// is random
I guess the easiest way would be to call the function from the getRandomPost by passing a default variable through.
public function show($id, $randomPost = false) {
$post = Post::findOrFail($id);
return view('posts.show', compact('post', 'randomPost'));
}
public function getRandomPost() {
$post = Post::inRandomOrder()->where('is_published', 1)->first();
$this->show($post->id, true);
}
So i work with Laravel, and i use Laravel excel to load excel/csv files, but my files contains empty rows and i want to delete every empty row.
this is my code :
Excel::selectSheetsByIndex(0)->load($path, function($reader){
$results = $reader->noHeading()->toArray();
foreach ($results as $row) {
//my code
}
}, 'UTF-8');
So please if someone has any idea how i can do that i will be very appreciative
I think you can do it in this way
/** #var LaravelExcelReader $data */
$data = \Excel::load('file.xls', function ($reader) {
$reader->limitRows(20);
$reader->ignoreEmpty();
})->get()->toArray();
# remove empty rows
$data = array_filter($data);
use ToCollection method the wrap everything within if($row->filter()->isNotEmpty())
public function collection(Collection $rows)
{
foreach($rows as $row) {
if($row->filter()->isNotEmpty()){
// you logic can go here
$user = User::create([
'name' => ucwords($row['name']),
'class' => $row['class'],
...
]);
}
}
}
I'm newbie in codeigniter and still learning. Anyone can help for sample in basic view, add, update, delete operation and queries in codeigniter will gladly appreciated.
Just a simple one like creating addressbook for newbie.
thanks,
best regards
Some sample queries in Codeigniter
class Names extends Model {
function addRecord($yourname) {
$this->db->set("name", $yourname);
$this->db->insert("names");
return $this->db->_error_number(); // return the error occurred in last query
}
function updateRecord($yourname) {
$this->db->set("name", $yourname);
$this->db->update("names");
}
function deleteRecord($yourname) {
$this->db->where("name", $yourname);
$this->db->delete("names");
}
function selectRecord($yourname) {
$this->db->select("name, name_id");
$this->db->from("names");
$this->db->where("name", $yourname);
$query = $this->db->get();
return $this->db->result();
}
function selectAll() {
$this->db->select("name");
$this->db->from("names");
return $this->db->get();
}
}

More about codeigniter views over here
You can use this as an example
class Crud extends Model {
// selecting records by specifying the column field
function select()
{
// use $this->db->select('*') if you want to select all the records
$this->db->select('title, content, date');
// use $this->db->where('id', 1) if you want to specify what row to be fetched
$q = $this->db->get('mytable');
// to get the result
$data = array();
// for me its better to check if there are records that are fetched
if($q->num_rows() > 0) {
// by doing this it means you are returning array of records
foreach($q->result_array() as $row) {
$data[] = $row;
}
// if your expecting only one record will be fetched from the table
// use $row = $q->row();
// then return $row;
}
return $data;
}
// to add record
function add()
{
$data = array(
'title' => 'My title' ,
'name' => 'My Name' ,
'date' => 'My date'
);
$this->db->insert('mytable', $data);
}
// to update record
function update()
{
$data = array(
'title' => $title,
'name' => $name,
'date' => $date
);
$this->db->where('id', 1);
$this->db->update('mytable', $data);
}
// to delete a record
function delete()
{
$this->db->where('id', 1);
$this->db->delete('mytable');
}
}
Some of this are from codeigniter userguide.
To view the records,
If return data is array of records,
foreach($data as $row)
{
echo $row['title'] . "<br />";
}
If the return data is an object (by using $q->row),
echo $data->title;
This is just a few examples or CRUD in Codeigniter. Visit the codeigniter userguide.
