[英]Method as Condition in While Loop
Need to create a Method like WordPress's function have_posts()
for templating. 需要创建类似于WordPress函数have_posts()
进行模板化。
Method goes something like this: 方法是这样的:
class posts{
public function have_posts(){
$query = 'SELECT * FROM posts';
$result = mysql_query($query);
return mysql_fetch_array($result);
}
}
Using the class in the template (theme): 在模板(主题)中使用类:
$posts = new posts;
while($row = $posts->have_posts()){
echo $row['post_title'];
}
But I am trying to achieve something like: 但我正在努力实现以下目标:
<?php while(have_posts()){ ?>
<h1><?php post_title(); ?></h1>
<?php } ?>
Alternatives & Suggestions are also welcomed :) 也欢迎其他选择和建议:)
For your specific question, the following should work 对于您的特定问题,以下应该有效
class posts
{
private $_result;
private $_current;
public function __construct()
{
$query = 'SELECT * FROM posts';
$this->_result = mysql_query($query);
}
public function have_posts()
{
return ($this->_current = mysql_fetch_array($this->_result));
}
public function post_title()
{
echo $this->_current['title'];
}
}
<?php $posts = new posts(); ?>
<?php while($posts->have_posts()){ ?>
<h1><?php $posts->post_title(); ?></h1>
<?php } ?>
