Php 如何在CodeiCenter中为搜索查询联接表
您好,我有以下搜索用于查找信息的功能:Php 如何在CodeiCenter中为搜索查询联接表,php,mysql,codeigniter,activerecord,Php,Mysql,Codeigniter,Activerecord,您好,我有以下搜索用于查找信息的功能: function get_search(){ $property_location = $this->input->post('property_location'); $property_bedroom = $this->input->post('property_bedroom'); $property_bathroom = $this->input->post
function get_search(){
$property_location = $this->input->post('property_location');
$property_bedroom = $this->input->post('property_bedroom');
$property_bathroom = $this->input->post('property_bathroom');
$property_status = $this->input->post('property_status');
$property_type = $this->input->post('property_type');
$this->db->like('property_location',$property_location);
$this->db->like('property_beds',$property_bedroom);
$this->db->like('property_bath',$property_bathroom);
$this->db->like('property_state',$property_status);
$this->db->like('property_type',$property_type);
$query = $this->db->get('property');
error_log($this->db->last_query());
return $query->result();
}
如何将另一个表(如property_images)连接到搜索中,以便在结果中包含数据
以下是我的看法:
<div class="container">
<div class="page-header">
<h4>Your search returned the following result(s):</h4>
</div>
<?php foreach ($results as $item): ?>
<div class="row">
<div class="col-md-3">
<div class="thumbnail">
<img
src="<?php echo base_url() . 'data/images/property_images/' . $item->image_name; ?>"
class="img-responsive">
</div>
</div>
<div class="col-md-9">
<h4 style="margin-top: 0;">
<a href="/property/view/<?php echo $item->property_slug;?>"><?php echo $item->property_name; ?></a>
</h4>
<p><?php echo $item->property_description;?></p>
<p>Location: <?php echo $item->property_location ?> | Price: R<?php echo $item->property_price ?></p>
</div>
</div>
<hr>
<?php endforeach; ?>
</div>
您的搜索返回了以下结果:
图像名称;?>"
class=“img响应式”>
地点:|价格:R
您可以使用正在使用的活动记录类的join()
方法来完成
join($table, $cond[, $type = ''[, $escape = NULL]])
Parameters:
$table (string) – Table name to join
$cond (string) – The JOIN ON condition
$type (string) – The JOIN type
$escape (bool) – Whether to escape values and identifiers
Returns:
CI_DB_query_builder instance (method chaining)
Return type:
CI_DB_query_builder
Adds a JOIN clause to a query.
在您的示例中:
$this->db->like('property_location',$property_location);
$this->db->like('property_beds',$property_bedroom);
$this->db->like('property_bath',$property_bathroom);
$this->db->like('property_state',$property_status);
$this->db->like('property_type',$property_type);
$this->db->like('property_images.imageField', $imageFieldValue); // Observe change here.
$query = $this->db->get('property');
$this->db->join('property_images','property.your_id_field = property_images.your_id_field'); // Observe change here.

$this->db->like('property_location',$property_location);
$this->db->like('property_beds',$property_bedroom);
$this->db->like('property_bath',$property_bathroom);
$this->db->like('property_state',$property_status);

$this->db->like('property_images.imageField', $imageFieldValue); // Observe change here.
$query = $this->db->get('property');
$this->db->join('property_images','property.your_id_field = property_images.your_id_field'); // Observe change here.
您可以在查询中使用join:
function get_search(){
$property_location = $this->input->post('property_location');
$property_bedroom = $this->input->post('property_bedroom');
$property_bathroom = $this->input->post('property_bathroom');
$property_status = $this->input->post('property_status');
$property_type = $this->input->post('property_type');
$this->db->like('property_location',$property_location);
$this->db->like('property_beds',$property_bedroom);
$this->db->like('property_bath',$property_bathroom);
$this->db->like('property_state',$property_status);
$this->db->like('property_type',$property_type);
$this->db->join('property_images','property.property_image_id=property_images.property_image_id'); //add this line in your code
$query = $this->db->get('property');
error_log($this->db->last_query());
return $query->result();
}
希望它能帮助您……您可以在查询中使用join:
function get_search(){
$property_location = $this->input->post('property_location');
$property_bedroom = $this->input->post('property_bedroom');
$property_bathroom = $this->input->post('property_bathroom');
$property_status = $this->input->post('property_status');
$property_type = $this->input->post('property_type');
$this->db->like('property_location',$property_location);
$this->db->like('property_beds',$property_bedroom);
$this->db->like('property_bath',$property_bathroom);
$this->db->like('property_state',$property_status);
$this->db->like('property_type',$property_type);
$this->db->join('property_images','property.property_image_id=property_images.property_image_id'); //add this line in your code
$query = $this->db->get('property');
error_log($this->db->last_query());
return $query->result();
}
