【问题描述】：
我目前正在使用一个 codeigniter 应用程序，它可以让您根据各种条件过滤作业，但是它不能很好地正常工作，基本上，应该发生的是过滤用户后应该显示结果这种格式，
<section style="display: block;" class="employer">
<div class="job_holder">
<img src="http://lcl.doctrine.com/media/uploads/users/large_moovjob_large4.gif" alt="Test Company" height="148" width="198">
<dl>
<dt>2</dt>
<dd>Matches</dd>
</dl>
<!--<a href="" class="fave">Fave</a>-->
<ul class="job_listings">
<li>
+ <a href="http://lcl.doctrine.com/jobwall/getjob/4" class="openjob">
PHP Backend Web Developer
</a>
</li>
<li>
+ <a href="http://lcl.doctrine.com/jobwall/getjob/5" class="openjob">
Website Designer
</a>
</li>
</ul>
</div>
</section>
但是我得到的是标记重复了两次，我循环了一个看起来像这样的数组，
Array
(
[0] => Array
(
[job_id] => 4
[job_title] => PHP Backend Web Developer
[salary] => 23000
[job_tags] => IT,Media
[retrain] => no
[job_extras] => We offer a very generous bonus scheme, including a company car, profit bonuses and a pension package.
[job_summary] => The job consists of a 60/40 spilt of PHP and front end skills, you will be expected to be proficient in, PHP, OO, MySQL and JAVASCRIPT
[job_description] => The job is a 60/40 split between the front and the backend of coding. You will be working within a team of 4 using an inhouse framework and where applicable an in house CMS.

[company_name] => Test Company
[company_summary] => Test company is excatly what it says it is a test company, we have created this test company so that we can see that moovjob is functioning as it should be and that everything is upload, saving, applying and generally saving as we would expect. Hello

[logo_large] => large_moovjob_large4.gif
[employer_id] => 1

[1] => Array

[job_id] => 5
[job_title] => Website Designer
[salary] => 28000

[logo_large] => large_moovjob_large4.gif
[employer_id] => 1
)
)
我通过执行以下代码循环它，
<?php if(is_array($jobs)) : ?>
<pre><?php print_r($jobs); ?></pre>
<?php $count = count($jobs); ?>
<?php foreach ($jobs as $j) : ?>
<section class="employer">
<div class="job_holder">
<img src="<?php echo base_url(); ?>media/uploads/users/<?php echo $j['logo_large']; ?>" width="198" height="148" alt="<?php echo $j['company_name']; ?>"/>
<dl>
<dt><?php echo $count; ?></dt>
<dd>Matches</dd>
</dl>
<!--<a href="" class="fave">Fave</a>-->
<ul class="job_listings">
<?php foreach ($jobs as $j) : ?>
<?php $job = $j['job_title']; ?>
<li>
+ <a href="<?php echo base_url(); ?>jobwall/getjob/<?php echo $j['job_id']; ?>" class="openjob">
<?php echo $job; ?>
</a>
</li>
<?php endforeach; ?>
</ul>
</div>
</section>
<?php endforeach; ?>
基本上我需要做的是呼应公司名称，然后是公司的工作，然后继续前进，它目前正在做的事情是呼应公司名称，然后是它的工作，然后重复自己为$jobs 有 2 个结果，但它们都是针对同一家公司的。
我的模型中的代码如下，
public function search($salary = null, $location = null, $tags = null, $quick_tags = null)
{
$this->db->select('job_id, job_title, salary, job_tags, retrain, job_extras, job_summary, job_description, company_name, company_summary, logo_small, logo_large, employers.employer_id');
$this->db->from('jobs');
$this->db->join('employers', 'employers.employer_id = jobs.employer_id', 'left');
if(isset($salary)) {
$this->db->where('jobs.salary >=', $salary);
}
if(isset($location)) {
$this->db->where('jobs.city', $location);
}
if(isset($tags)) {
$this->db->like('jobs.job_tags', $tags);
}
if(isset($quick_tags) && is_array($quick_tags)) {
foreach ($quick_tags as $index => $value) {
if ($index == 0)
$this->db->like('jobs.job_tags', $value);
else
$this->db->or_like('jobs.job_tags', $value);
}
}
$this->db->group_by('jobs.job_title');
$query = $this->db->get();
return $query->result_array();
}
