The Problem is update function is doesn't work, and i didn't get any error, can anyone help me?

Answer 1

Ensure the $fillable array is set correctly on your Eloquent model.

class ItemName extends Model
{

    protected $fillable = [
        'inc',
        'item_name',
        'short_name',
        'definition_eng',
        'definition_ind',
    ];

    // ..

}

Normally Laravel will create a MassAssignmentException if you call update() and have not defined the $fillable array.

As soon as you define anything on the $fillable array Laravel will silently ignore any additional values.

I encountered this problem

My update function in the controller is as follows

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Models\Person  $person
     * @return \Illuminate\Http\Response
     */
    public function update(Person $person, Request $request)
    {
        $person->update($request->validate([
            'forename' => 'required',
            'surname' => ''
        ]));

        return redirect('/people');
    }

My routes/web.php file had the following route:

Route::put('/people/{id}', [PersonController::class, 'update']);

To fix this, the wildcard match should be the same as the model name.

Route::put('/people/{person}', [PersonController::class, 'update']);

Answer 3

Try with fill instead of update.

 $itemName->fill($request->all());
 $itemName->save();

Hope this will help you

Answer 4

你应该试试这个：

$items = ItemName::where($itemName)->update($request->all());

Answer 5

请注意，如果您的更新值与旧记录相同，则 update() 函数会响应 false。
