I have a form where users enter their details along with their image. I've written code that gets the image and stores it in a column named 'image' as bin file, the data type of the column is a blob. However, when I try to display the image in the view, The image is not getting displayed.
Controller
<?php
public function showProfile($username)
{
$user_details = User::get()->where('name', $username);
return view('profile-page', ['user_details' => $user_details]);
}
View
<div class="panel-body">
<form class="form-horizontal" role="form" method="POST" action="{{ url('/user-post') }}">
{{ csrf_field() }}
<input type='hidden' value='{{Session::token()}}' name="_token">
#foreach($user_details as $user)
<img src="data:image/jpeg;base64,'.base64_encode( {{$user->image}} ).'"/>
<p>
<h2>
<center>hello This is {{$user->name}} </center>
</h2>
<h2>
<center>I am a {{$user->nationality}} </center>
</h2>
<h2>
<center>This great person was born on {{$user->dobday}}-{{$user->dobmonth}}-{{$user->dobyear}} </center>
</h2>
<h2>
<center>Contact me here {{$user->email}} </center>
</h2>
#endforeach
</form>
</div>
All the details are shown as expected except the image, what's the problem here?
You made mistake here:
base64_encode( {{$user->image}}
try like this:
{{ base64_encode($user->image) }}

I've made a blog and now I'm trying to implement a comment section. I want it so that when the user tries to post, it's saves the comment and redirects the user to the same page. But when I write a comment and try to post it, the application redirects me to a different page. I'm learning how to make a blog with laravel, so I don't know when to use url and when to use routes. Here's the code that I've written.
#auth
<div class="card ml-5 col-lg-8">
<ul class="list-group list-group-horizontal">
<h5 class="list-group-item active">
Comments
<h5>
<div class="card-body">
<form method="post" action="{{url('save-comment/'.Str::slug($blog->title).'/'.$blog->id)}}">
#csrf
<textarea name="comment" class="form-control py-5"></textarea>
<input type="submit" class="btn btn-primary mt-3">
</div>
</ul>
</div>
#endauth
<div class="card ml-5 col-lg-8">
<h5 class="card-header mb-4">Comments<span class="badge badge-info ml-2"> {{count($blog->comments)}}</span></h5>

#if($blog->comments)
#foreach($blog->comments as $comment)

If there's someone willing to assist come up with a solution to this problem, please assist me. I think the problem lies where I've written the url lies. When I change the url to route, it gives me an error of route not defined.
Route::resource('/blog','App\Http\Controllers\BlogController');
It redirects you to an empty page because you made a mistake on the url of your route. In your web.php file, your route is :
Route::post('save_comment/{slug}/{id}', 'App\Http\Controllers\BlogController#save_comment')->name('save_comment');
While in your form you wrote save-comment/ :
<form method="post" action="{{url('save-comment/'.Str::slug($blog->title).'/'. $blog->id)}}">
The error is due to this. I therefore advise you to modify the action in your form like this save_comment/:
<form method="post" action="{{url('save_comment/'.Str::slug($blog->title).'/'. $blog->id)}}">
This should be fixed !
Please change your code like this and check...
action="{{route('save_comment', $blog->id])}}"
Route::post('save_comment/{id}','App\Http\Controllers\BlogController#save_comment')->name('save_comment');

Hey guys, I'm new to all this, and not sure if I'm calling the route incorrectly or wrong application of my controller function. Obviously I'm trying to add a user from a list into a group. Please Help! I've been a little lost with this and looking for some help to understand where my errors are. Many thanks!
EDIT**
now log reading..
"'hobby_id' cannot be null"..
I have tried to change the variable to take the group id. and that reads error "trying to get id of non-object"
but am I not assigning hobby_id as the group_id?
The problem is that I want to add into 'hobby_id' the 'id' of the current group which this function is being called.
I'm making a "teacher's" app, and I want to make a log-in page which changes depending if there's registered users in the database or not.
I want to make a redirection button to a create user page if there aren't auth users in database, and to make a select user view if the database have one or more users.
The problem is that I don't know how to exactly do this, 'cause the view always shows me the first statement (what I've got in the if), also if in the database are registered users. Can anyone help me with this please?
This is the blade file:
#if (empty(Auth::user()->id))
<div class="grid-item" id="grid-item5">
<div id="title">
<h1>Welcome</h1>
<p>We see there aren't users</p>
</div>
<div id="loginForm">
<button type="button" onclick="window.location='{{ url("/newUser") }}'">Button</button>
</div>
</div>
#else
<div class="grid-item" id="grid-item5">
<div id="title">
<h1>Select an user</h1>
</div>
<div id="loginForm"></div>
</div>
#endif
Here you have the controller index method:
public function index()
{
$users = User::all();
return view('/', compact('users'));
}
And finally here you have the page:
The following code is the sample for it, kindly replace code accordingly
#if(!$user)
//show button
#else
//dont show button
#endif
I think your question is you want to check if there is user in database.
So no need to check if the user authenticated but to check if there is user on the database.
In your controller
public function index() {
return view('/', ['users' => User::all()]);
}
and in your blade file
#if(!$users)
<div class="grid-item" id="grid-item5">
<div id="title">
<h1>Welcome</h1>
<p>We see there aren't users</p>
</div>
<div id="loginForm">
<button type="button" onclick="window.location='{{ url("/newUser") }}'">Button</button>
</div>
</div>
#else
<div class="grid-item" id="grid-item5">
<div id="title">
<h1>Select an user</h1>
</div>
<div id="loginForm"></div>
</div>
#endif
This function will get the current authenticated user: Auth::user(). I guess what you are trying to achieve is #if(empty($users)) where $users is the variable you are passing on controller.
If you want to verify if the user that accessed to that view is authenticated you can simply use #auth and #guest.
Also i would suggest you to change your button to an <a> tag and your href would be <a href="{{ route('route.name') }}" where route.name would be defined in your routes file.
in your controller:
you can create a folder inside views called users and then the index.blade.php (views/users/index.blade.php)
public function index()
{
$users = Users::all();
return view('users.index')->with('users', $users);
}
in your view:
#if(count($users) < 1)
...
#else
...
#endif
count is validating if the $users array length is less then 1 (in other words if the array is empty).
Alternative you can you isEmpty()
#if($users->isEmpty())
...
#else
...
#endif
I have my image path in my database and now, i am trying to get the image into my html grid. But when i try to fetch the image, i get an error
Property [path] does not exist on this collection instance.
But then, there is path attribute in my table in the database. Has it got to be an error from my models? My model seems right to me. Anyway what am i not doing right here, please?
Thanks for your concern

public function products()
{
return $this->belongsTo(Product::class);
}
Product_images
public function images()
{
return $this->hasMany(Image::class);
}
You need to make a foreach as it's give you a collection.
Hence, try to display it like:
#foreach($product->images as $image)
#if($image->path)
<img src="{{ $image->path }}" alt=" " class="img-responsive" />
#else
<p>No image to display!</p>
#endif
#endforeach
Hope this will helps you!
This happens because the Product model hasMany Images.
In order to reach the path property you should do this:
#foreach($product->images as $image)
{{$image->path}}
#endforeach
Or do this in your Product Model and change your database structure
public function image()
{
return $this->hasOne(Image::class);
}
I hope it helps.
If your path does not any issue, the following is the correct way to display an image in Laravel blade template.
<img src="{{URL::asset('directory/name_of_image_file.file_format')}}">
You don't have field path in DB images
You code must be:
<img src="{{$product->images->[you field in Db images]}}" alt=" " class="img-responsive" />
HTML
#foreach($products as $product)
<figure>
<div class="snipcart-item block">
<div class="snipcart-thumb">
<img src="{{$product->images->first()->path}}" alt=" " class="img-responsive" />
<p>{{$product->name}}</p>
<h4>GH₵ {{ number_format($product->price,2) }} </h4>
</div>
<div class="snipcart-details top_brand_home_details">
<form action="#" method="post">
<fieldset>
</fieldset>
</form>
</div>
</div>
</figure>
#endforeach
<a href="{{ route('product.view', $product->slug)}}">
<img src="{{$product->images->first()->path}}" alt=" " class="img-responsive" />
</a>
$product->images is a collection, you need to get the image out of the collection. for now I have used the first() which will fetch the first image, you may want to loop through the collection depending on your scenario. You may want to read about an answer have written here
In my application, I've always been able to pass data to any view as one would normally do using view('myView', compact('data'));. As of today, any view I try to render this way times out. I'm getting the error Maximum execution time of 120 seconds exceeded in Whoops!. I tried increasing php.ini and httpd.conf timeout times but no cigar. It's really odd and it doesn't make sense to me because I've always been able to render my views almost instantly, even when retrieving 15k+ records from the database and passing them to the view like I've always done.
My controller:
use App\Product;
use Illuminate\Support\Facades\Session;
class HomeController extends Controller {
public function __construct()
{
$this->middleware('auth');
}
public function index()
{
//the controller is normally like this
//$products = Product::paginate(16);
//return view('home', compact('products'));
//I'm testing with these 2 lines below but no cigar.
$product = Product::wherePid(303)->first();
return view('test', compact('product'));
}
}
The test view I created:
#extends('app')
#section('content')
{{ $product->name }}
#stop
My application view:
#extends('app')
<pre>{{ var_dump(Session::all())}}</pre>
#section('content')
<div class="row">
#foreach($products as $product)
<div class="col-xs-6 col-sm-3 col-lg-3 col-md-3">
<?php
if($product->img[7] == 'm' || $product->img[7] == 'M') echo "<div class='continenteIcon'></div>";
else echo "<div class='jumboIcon'></div>";
?>
<div class="thumbnail">
<a href="products/{{$product->pid}}"><img src="{{$product->img}}" title="
<?php
if($product->dispname != '') echo $product->dispname;
else echo $product->name;
?> ">
</a>
<div class="caption">
<h4>
<a style="text-decoration:none;" class="wordwrap" title="
<?php
if($product->dispname != '')
echo $product->dispname;
else echo $product->name;
?>" href="products/{{$product->pid}}">
<?php
if($product->dispname != '')
echo $product->dispname;
else echo $product->name;?>
</a>

The problem doesn't only happen in this view, but every single time I try to fecth someting from the database and pass it to the view to render. I keep getting timeouts and I can't seem to fix it no matter what I do.
I am clueless why this is happening. It seems like it started out of the blue. I have no Idea what could be causing this issue.
Any help?
P.S.: I'm using Wamp.
EDIT: I forgot to add something that might be important:
Everything is up and running in Wamp. If I dd() out the query result and do not render the view
$products = Product::paginate(16);
dd($products);
//return view('home', compact('products'));
this is fast, as it always used to be. And by fast I mean it takes less than 1 second to retrieve everything I need. But if I render the view with
return view('home', compact('products'));
everything just stalls and I get a 500 (I checked with Fiddler2 and after the page stops loading, the request status is 500)
It seems like you may be requesting too many records which may be using too much of your RAM. I would use the chunk command to help you with managing the amount you're requesting.
For example:
User::chunk(200, function($users)
{
foreach ($users as $user)
{
//
}
});
First check logs.
Next try to dd($product)
Next if you try to render view with last 2 lines (getting first record) remove pagination from template.
Clean template to minimum e.g.
#extends('app')
#section('content')
<div class="row">
#foreach($products as $product)
#endforeach
</div>
#stop
I just sorted it out. The issue was in the following block of code in app.blade.php.
$size = Session::get('size');
...
<input type="text" value="'.Session::get($item).'">
...
I was messing around with data from an existing session and everything was working fine. I assumed I was doing it right. I wasn't. Not by a chance :)
Assumption is the mother of all screw ups.
Surrounded the whole block with if(Session::has('size') and everything is blazing fast and running smoothly as usual.
Thanks #Pyton for pointing me out into the right direction and thanks everyone for your contribution.
