Hi i wanna to display image from server. It works when i got a record in DB. But if there isnt record in DB (no img uploaded) i wanna display NO LOGO

here is my codes:

public function display_logo($service_id){
    $img_path = DB::table("logo_table")->get()->where("service_id",$service_id);        
       return $img_path[0];}


public function my_name($id)
{
    $name = $this->get_user()->where('id',$id);
    $image_path = $this->display_logo($id);
    $count = count($image_path);
    return view('my_object', compact("name","image_path","count"));
}

And the blade

 @if ($count>0)
    <img src="{{$image_path->logo_path}}{{$image_path->logo_name}}" width=100 height=100";>
@else
    <h2>No image</h2>
@endif

If there is record in DB then i got the img but if there isnt. i got :Undefined offset: 0 How can i solve it. (Sorry if my english is bad :))

You should chek for a valid value for $img_path or return null eg:

  public function display_logo($service_id){
    $img_path = DB::table("logo_table")->get()->where("service_id",$service_id);        
       return (isset($img_path) ? $img_path[0] : NULL );
   } 

How to avoid undefined offset error in PHP ?, If we access an index that does not exist or an empty offset, it will lead to an undefined offset error. Example: Following PHP code explains how we can access� After making the changes, I am also no longer able to delete records. When I click delete then the record disappears from the datatable but is not removed from the database and if I refresh the page is shows again in the datatable. Editing the record still works fine.

You could check how many images are returned and return NO LOGO if there aren't any...

return (count($img_path)>0) ? $img_path[0] : "NO LOGO";

or just check if the first image is set...

return isset($img_path[0]) ? $img_path[0] : "NO LOGO";

Not sure what value you need to return, but just change "NO LOGO" to the value your after. May need to use [].

An "undefined offset" exception occurs in PHP when trying to access an array key that does not exist. In this case an empty array is being returned since there are no matching records.

This error can be reproduced with this code:

$img_path = [];
echo $img_path[0]; // undefined offset exception

An undefined offset exception can be avoided by using a null-coalescing operator (requires PHP 7.0+) or by checking if the index exists before accessing it.

Solution with null-coalescing operator: (PHP 7.0+)

public function display_logo($service_id){
    $img_path = DB::table("logo_table")->get()->where("service_id",$service_id);  
       // fallback to null if [0] does not exist
       return $img_path[0] ?? null;
}

Solution with explicit check:

public function display_logo($service_id){
    $img_path = DB::table("logo_table")->get()->where("service_id",$service_id);  
       // fallback to null if [0] does not exist
       return isset($img_path[0]) ? $img_path[0] : null;
}

php undefined offset Code Example, If preg_match did not find a match, $matches is an empty array. So you should check if preg_match found an match before accessing� Sometimes you may want to update an existing record in the database or create it if no matching record exists. In this scenario, the updateOrInsert method may be used. The updateOrInsert method accepts two arguments: an array of conditions by which to find the record, and an array of column and value pairs containing the columns to be updated.

You have to try this way to find data from MODELs for NOT NULL clause. Do it for all your model that checks not null condition. Because your model has no element with key 0 in this case that why it returns Undefined offset 0 SibuPayment::find()->where(['not', ['Sibu_Payment.total_payment' => null]])->all(); For
