显示成功消息但未存储到数据库 laravel

Question

这是控制器的代码：

public function save_product(Request $request){
    $request->validate([
        'product_name' => 'required',
        'product_price' => 'required',
        'product_category' => 'required',
        'description' => 'nullable',
        'image1' => 'required',
        'image2' => 'nullable',
        'image3' => 'nullable',
    ], [
        'product_name.required' => 'Product name field required',
        'product_price.required' => 'Asking price field required',
        'product_category.required' => 'Product category field required',
        'image1.required' => 'You need a upload image-1 field',
    ]);

    if($request->hasFile('image1') || $request->hasFile('image2') || $request->hasFile('image3')){
        $file1 = $request->file('image1');
        $file2 = $request->file('image2');
        $file3 = $request->file('image3');
        $text1 = $file1->getClientOriginalExtension();
        $text2 = $file2->getClientOriginalExtension();
        $text3 = $file3->getClientOriginalExtension();
        $fileName1 = time().'.'.$text1;
        $fileName2 = time().'.'.$text2;
        $fileName3 = time().'.'.$text3;
        $file1->move('uploads/product_image', $fileName1);
        $file2->move('uploads/product_image', $fileName2);
        $file3->move('uploads/product_image', $fileName3);
        $product = Product::create([
            'image1'=>$fileName1,
            'image2'=>$fileName2,
            'image3'=>$fileName3,
            'product_category' => trim($request->input('product_category')),
            'product_name' => trim($request->input('product_name')),
            'product_price' => trim($request->input('product_price')),
            'description' => trim($request->input('description')),
        ]);
    }
    return redirect()->route('add_product')
        ->with('success','Successfully added Product!');
}

这是刀片模板的代码：

路线： Route::post('/admin/add_product','App\Http\Controllers\Admin\AdminController@save_product') ->name('save_product')->middleware('admin');

型号： 受保护的 $fillable = [ '产品名称'， '产品分类'， 'product_price', '描述'， '图像 1', '图像2'， '图像 3', ];

迁移：

public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->id();
        $table->string('product_name');
        $table->string('product_category');
        $table->string('product_price');
        $table->text('description')->nullable();
        $table->string('image1');
        $table->string('image2')->nullable();
        $table->string('image3')->nullable();
        $table->timestamps();
    });
}

我在我的代码中找不到任何错误，请帮助我找出答案。提前致谢。

Answer 1

您必须为每张图片分别设置 if 条件。试试这个：

        $fileName1='';
        $fileName2='';
        $fileName3='';
        if($request->hasFile('image1')) {
            $file1 = $request->file('image1');
            $text1 = $file1->getClientOriginalExtension();
            $fileName1 = time() . '.' . $text1;
            $file1->move('uploads/product_image', $fileName1);
        }
        if($request->hasFile('image2')) {
            $file2 = $request->file('image2');
            $text2 = $file2->getClientOriginalExtension();
            $fileName2 = time() . '.' . $text2;
            $file2->move('uploads/product_image', $fileName2);
        }
        if($request->hasFile('image3')) {
            $file3 = $request->file('image3');
            $text3 = $file3->getClientOriginalExtension();
            $fileName3 = time() . '.' . $text3;
            $file3->move('uploads/product_image', $fileName3);
        }
        
        $product = Product::create([
            'image1'=>$fileName1,
            'image2'=>$fileName2,
            'image3'=>$fileName3,
            'product_category' => trim($request->input('product_category')),
            'product_name' => trim($request->input('product_name')),
            'product_price' => trim($request->input('product_price')),
            'description' => trim($request->input('description')),
        ]);
        
        if($product){
        return redirect()->route('add_product')->with('success','Successfully added Product!');
        }
        else{
        return redirect()->back()->with('error','Error!');
        }

在表单标签中使用 enctype="multipart/form-data"。
