Laravel 4 - Many to Many - pivot table not updating - laravel

Question

I get no obvious errors when adding a new job to my database.
My industry job goes into the jobs table but the relationship with divisions in my join table goes nowhere. I just can't see where I'm going wrong
JOIN TABLE
division_industryjob
division_id
industryjob_id
divisions
id
division_name
industryjobs
id
job_title
MODELS
Division.php
<?php
class Division extends \Eloquent {
protected $table = 'divisions';
/**
* Industry Jobs relationship
*/
public function industryjobs()
{
return $this->belongsToMany('IndustryJob');
}
}
IndustryJob.php
<?php
class IndustryJob extends \Eloquent {
protected $table = 'industryjobs';
public function divisions()
{
return $this->belongsToMany('Division');
}
}
ROUTES
Route::get('industry-jobs/add', 'AdminController#getCreateIndustryJob');
Route::post('industry-jobs/add', 'AdminController#postCreateIndustryJob')
CONTROLLER
// Create Industry - Get (empty form - new entry)
public function getCreateIndustryJob()
{
View::share('page_title', 'Create a new Industry Job Role');
View::share('sub_page_title', 'Ex: Mechanical Technician');
return View::make('admin/industry-jobs/create');
}
// Create Industry - Post
public function postCreateIndustryJob()
{
//validate user input
$rules = array(
'job_title' => 'Required|Min:3|Max:80'
);
$validation = Validator::make(Input::all(), $rules);
If ($validation->fails())
{
return Redirect::to('/admin/industry-jobs/add')->withErrors($validation);
} else {
$industryjob = new IndustryJob;
$industryjob->job_title = Input::get('job_title');
$industryjob->job_description = Input::get('job_description');
$industryjob->job_qualifications = Input::get('job_qualifications');
if (isset($input['divisions'])) {
foreach ($input['divisions'] as $divId) {
$div = Division::find($divId);
$industryjob->divisions()->save($div);
}
}
$industryjob->save();
return Redirect::to('/admin/industry-jobs')->with('message', 'Industry Job created successfully');
}
}

Answer 1

You are saving the Parent model afterwards so it's not working. Save the Parent model before you save the Child Model, so it should be something like this:
$industryjob = new IndustryJob;
$industryjob->job_title = Input::get('job_title');
$industryjob->job_description = Input::get('job_description');
$industryjob->job_qualifications = Input::get('job_qualifications');
$industryjob->save();
Then save the related models using sync because it's many-to-many relationship and those related models are already created and available in the database:
if (isset($input['divisions'])) {
// Pass the array of ids to sync method
$industryjob->divisions()->sync($input['divisions']);
}
If you use the foreach loop then you may use something like this;
foreach ($input['divisions'] as $divId) {
$industryjob->divisions()->attach($divId);
}
