Linking and displaying data from tables in cake php 3 - php

Question

I am trying to display the names from the types table in my jobs/index.ctp
not sure how to echo this, so far I have written this
but it is not working but also not giving any error message
class Jobs extends Table
{
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('jobs');
$this->setDisplayField('title');
$this->setPrimaryKey('id');
$this->addBehavior('Timestamp');
$this->belongsTo('Categories', [
'foreignKey' => 'category_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Users', [
'foreignKey' => 'user_id',
'joinType' => 'INNER'
]);
$this->belongsTo('Types', [
'foreignKey' => 'type_id',
'joinType' => 'INNER'
]);
}
class Types extends Table
{
/**
* Initialize method
*
* #param array $config The configuration for the Table.
* #return void
*/
public function initialize(array $config)
{
parent::initialize($config);
$this->setTable('types');
$this->setDisplayField('name');
$this->setPrimaryKey('id');
$this->hasMany('Jobs', [
'foreignKey' => 'type_id'
]);
}
<?php
foreach ($jobs as $jobs):
?>
<li>
<div class="type"><span style="background:"> <?php echo $jobs['types']['name']; ?> </span></div>
<div class="description">
<h5><?php echo $jobs['title']; ?> (<?php echo $jobs['city']; ?> , <?php echo $jobs['postcode']; ?>)</h5>
<h6><strong>company Name: <?php echo $jobs['company_name']; ?></strong></h6>
<h6>Date Posted:<span id="list_date"> <?php echo $this->Time->Format($jobs['created'], "d MMMM y") ?> </span></h6>
It all works apart from this line <?php echo $jobs['types']['name'] ;?>

Answer 1

First off, your foreach loop should be foreach ($jobs as $job). Note the singular $job for the variable that tracks each particular job.
Following on that singular note, since Jobs belongTo Types, there is only a single type for each job, not multiple. As a result, the value you're looking for is
$job['type']['name'] ($job->type->name will likely also work). This all assumes that you've correctly used containment when loading the record; hence why I asked for that code to be shown too.
If Jobs had many Types, then you'd have $job['types'] (or $job->types), which would be an array of Type entities that you could iterate over.

Answer 2

For displaying the associated table data you need 3 things:
Association in Table,
$this->belongsTo('Types', [
'foreignKey' => 'type_id',
'joinType' => 'INNER'
]);
In controller (JobsController) specify the associated table using contain,
public function index() {
$jobs = $this->Jobs->find('all')->contain(['Types']);
//set jobs variable to make it available in .ctp file
}
In Jobs/index.ctp file
<?php echo $job['types']['name'] ;?>
