目前，我正在使用一个Codeigniter应用程序，它可以让您基于各种critieria来过滤作业，但是，它并不是很有效，基本上，应该发生的情况是，在过滤用户之后，应该以这种格式显示结果，
<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，我遍历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

我通过执行以下代码来遍历它，
<?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，我需要做的是先回荡公司名称，然后回荡公司职位，然后继续前进，此刻正在做什么，先回荡公司名称，然后回荡其职位，然后将自己重复为
$jobs有2个结果，但它们都属于同一家公司。我模型中的代码如下，
public function search($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 $query->result_array();
}
最佳答案
为了达到一致的结果
Employer
job posting 1
job posting 2
Other employer
job posting 1
您可能需要更改查询以首先按雇主对工作进行排序，以确保将工作分组在一起。
然后遍历您的数据（未经测试的伪代码）
employerCache = '';
for ($jobs as $job) {
if ($job['company_name'] != employerCache) {
// display company/employer header
$employerCache = $job['company_name'];
}
// display job posting
}
这将为您提供1个循环，而不是同一数据集上的两个嵌套循环
