Question

我是Phalcon的新人。我决定将Phalcon php作为Codeigniter的替代php框架。我正在实施一个带有标签的博客。第一个im插入标签的值是单个列到db中。我关注的标签插件示例来自：https://github.com/mfiels/tagsly/blob/master/index.html 它将多个值插入到单个列中，如“php，jquery，asp，html，css”。

现在我只需将db的值从这样的方式转换为伏特：

[controller]

$bloger = $this->modelsManager->executeQuery("SELECT * FROM Blogs ORDER BY Blogs.datetime DESC");
$this->view->setVar('blogs', $bloger);

[volt]        

<?php 
$blogTags = array(); 
$blogTags = $bloger->tags;
$tags = explode(',',$blogTags); 
foreach($tags as $taged){ ?>
<a class="tags" href="blog/tag/<?php echo($taged); ?>">
<?php echo($taged); ?> <span>[ 0 ]</span></a>
<?php } ?>

现在它的链接如："localhost/demo/blog/tag/php"或"localhost/demo/blog/tag/jquery" 我的问题是如何从db中检索每个标签相关数据？

我正在尝试这样查询：

[控制器]

public function tagAction($taged)
{
$tags = Blogs::findBytags($taged);
$tagData = array();
$tagData = explode(',', $tags->tags);
$similar = Blogs::find(["tags LIKE :title:","bind"=> ["title"=>'%'.$tagData.'%'],"order" => "datetime DESC limit 5"]);
$this->view->setVar('tagged', $similar);
$this->view->pick('blog/tagline');
}

[伏特]

{% for similar in tagged %}
{{tagged.btitle}}
{% endfor %}

但它没有按预期呈现。我怎样才能检索匹配的数据？

Answer 1

您可以遍历所有当前标记，然后逐个添加到查询中。在循环期间，您还要创建绑定元素数组。

[controller] 
...
$currenttags =  explode(',', $blog->tags);

$query          = Blogs::query();
$bindParameters = [];

for($i = 0; $i < count($currenttags); $i++) {
   $query->orWhere('tags LIKE :tag' . $i . ':');
   $bindParameters['tag' . $i] = '%' . $currenttags[$i] . '%';
}

$query->bind($bindParameters);
$similar = $query->execute();

$this->view->setVar('datas', $similar);

我的期望是当用户访问帖子的详细视图时，我想在该页面上显示该帖子相关/类似的其他帖子。由它的标签组成的相似性，现在我想通过这种方式：

[controller]    

public function showfullAction($id)
{
$blog = Blogs::findFirstByid($id); 
$this->view->setVar('detail', $blog);
$currenttags =  explode(',',$blog->tags);

I want to make Loop Throw....
$dataCount = count($currenttags);
$tags1 = $currenttags[0];
$tags1 = $currenttags[0];
$tags2 = $currenttags[1];
$tags3 = $currenttags[2];
$tags4 = $currenttags[3];
$tags5 = $currenttags[4];
$tags6 = $currenttags[5];
$tags7 = $currenttags[6];
$tags8 = $currenttags[7];
$tags9 = $currenttags[8];

if($dataCount == '1')
{
$similar = $this->modelsManager->executeQuery("SELECT Blogs.* FROM Blogs WHERE Blogs.tags LIKE '%$tags1%'");
}
elseif($dataCount == '2')
{
$similar = $this->modelsManager->executeQuery("SELECT Blogs.* FROM Blogs WHERE Blogs.tags LIKE '%$tags1%' or Blogs.tags LIKE '%$tags2%'");
}
elseif($dataCount == '3')
{
$similar = $this->modelsManager->executeQuery("SELECT Blogs.* FROM Blogs WHERE Blogs.tags LIKE '%$tags1%' or Blogs.tags LIKE '%$tags2%' or Blogs.tags LIKE '%$tags3%'");
}


 $this->view->setVar('datas', $similar);

等等......

[View]

{% for similar in datas %}
{{link_to('blog/showfull/'~similar.id,similar.btitle,'class':'cats')}}  
{% endfor %}

现在按预期工作但是还有另一个简单的小方法吗？请！ Thnx Timothy
