store function not saving data to the database

Question

I have a form in which a user can enter different data, the form contains two parts.

First part data will be saved to a table named pages (works perfect), the second part data will be saved to the table named parameters the table parameters contain a column which holds repeated data-name(not working),

Here is how table should look.

I have created a PIVOT table for paramaters and prebids table like this.

prebid_parameter,

public function up()
{
    Schema::create('prebid_parameter', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->bigInteger('prebid_id')->unsigned();
        $table->foreign('prebid_id')->references('id')->on('prebids');
        $table->bigInteger('parameter_id')->unsigned();
        $table->foreign('parameter_id')->references('id')->on('parameters');
    });
}

And page_prebid like this.

public function up()
{
    Schema::create('page_prebid', function (Blueprint $table) {
        $table->bigIncrements('id');
        $table->bigInteger('page_id')->unsigned();
        $table->foreign('page_id')->references('id')->on('pages');
        $table->bigInteger('prebid_id')->unsigned();
        $table->foreign('prebid_id')->references('id')->on('prebids');

    });
}

And I have created relationships like this.

Page model.

class Page extends Model
{
    protected $fillable =[
        "title",
        "articles",
        "status"
    ];
    public function prebids(){
        return $this->belongsToMany('App\Prebid');
    }
}

Prebid model.

class Prebid extends Model
{
    protected $fillable =["bidders_name"];

    public function parameters(){

        return $this->belongsToMany('App\Parameter');
    }
    public function pages(){

        return $this->belongsToMany('App\Page');
    }
}

And Parameter Model looks like this.

class Parameter extends Model
{
    protected $fillable =[
        "params_name",
        "params_value",
        "bidders_name"
    ];
    public function prebids(){
        return $this->belongsToMany('App\Prebid');
    }
}

And finanlly I have page controller store function to save the data like this.

 public function store(Request $request)
    {
        $page = Page::create([
            'title' => $request->get('title'),
            'articles' => $request->get('articles'),
            'status' => $request->get('status'),
        ]);

        $page->save();

        $page->tags()->sync($request->tags, false);
        $page->prebids()->sync($request->prebids, false);

        return redirect("/pages")->with("sucess", "data saved");
    }

When I add dd($request) in-store function I get the following

Note: parameter and prebid controllers are just empty

Now when I click the submit button only the first part data is saved to database, the rest are not saved to the database.

Here is repo: demo

What am I doing wrong with my code? am new to laravel though.

Answer 1

Couple of things are jumping out. I don't see an actual relationship for tags in the model you have displayed. Do you have a relationship on Page for tags ?

Also, this line:

$page->prebids()->sync($request->prebids, false);

is looking for the input from request for prebids but I'm not seeing that in your request object. I see params_value , which would not be sent to the sync() method. And thus, not be synced.

Give this a try:

$page->prebids()->sync($request->params_value, false);
