从数据库中取出最近三十天的数据并生成柱状图


答案：在终端用cd 命令进入文件目录 
说明：此处例子我是拿项目中的一个例子讲解的。 
1、新建一个项目 ：用终端输入：zf create project Airline 格式：zf create action project project-name 备注：这些格式可以在终端输入zf 查看 
2、新建一个action ：zf create action dirgramshow index 格式：zf create action action-name controller-name 
3、新建一个 model ：zf create db-table flightinformation 
action 层代码：indexController.php 
复制代码 代码如下:
 
public function indexAction () 
{ 
// action body 
$db = new Application_Model_DbTable_Flightinformation(); 
/*获取最近30天内的数目 
* select day(boo_time) as day,count(boo_autoid)as count,boo_time from bookinformation 
where flag_pass=0 and date_sub(now(), interval 30 day)<=date(boo_time) 
group by DATE_FORMAT(boo_time,'%m %d') 
*/ 
$sql = "select DATE_FORMAT(boo_time,'%m-%d') as day,count(boo_autoid)as count from bookinformation " . 
"where flag_pass=0 and date_sub(now(), interval 30 day)<=date(boo_time) " . 
"group by DATE_FORMAT(boo_time,'%m %d')"; 
$result = $db->getAllInfo($sql)->fetchAll(); 
$this->view->result=$result; 
} 
 
view 层代码：dirgramshow.phtml 
复制代码 代码如下:

var d=new Array(); 
var color=new Array(); 
<?php 
foreach ($this->result as $key => $value) {

d.push(new Array('<?php

//['#2D6B96', '#327AAD', '#3E90C9', '#55A7E3', '#60B6F0', '#81C4F0', '#9CCEF0'] 
var myData = d; 
var colors =color; 
var myChart = new JSChart('graph', 'bar'); 
myChart.setDataArray(myData); 
myChart.colorizeBars(colors); 
myChart.setTitle('Airline diagram'); 
myChart.setTitleColor('#8E8E8E'); 
myChart.setAxisNameX(''); 
myChart.setAxisNameY(''); 
myChart.setAxisColor('#C4C4C4'); 
myChart.setAxisNameFontSize(16); 
myChart.setAxisNameColor('#999'); 
myChart.setAxisValuesColor('#777'); 
myChart.setAxisColor('#B5B5B5'); 
myChart.setAxisWidth(1); 
myChart.setBarValuesColor('#2F6D99'); 
myChart.setBarOpacity(0.5); 
myChart.setAxisPaddingTop(60); 
myChart.setAxisPaddingBottom(40); 
myChart.setAxisPaddingLeft(45); 
myChart.setTitleFontSize(11); 
myChart.setBarBorderWidth(0); 
myChart.setBarSpacingRatio(50); 
myChart.setBarOpacity(0.9); 
myChart.setFlagRadius(6); 
myChart.setTooltip(['North America', 'U.S.A and Canada']); 
myChart.setTooltipPosition('nw'); 
myChart.setTooltipOffset(3); 
myChart.setSize(616, 321); 
/*myChart.setBackgroundImage('<?php 
//echo $this->baseUrl() . '/skin/image/ZJPchart_bg.jpg'?>');*/ 
myChart.draw(); 
} 
</script> 
</body> 
</html> 
 
model 层代码：Flightinformation.php 
复制代码 代码如下:
 
<?php 
class Application_Model_DbTable_Flightinformation extends Zend_Db_Table_Abstract 
{ 
protected $_name = 'flightinformation'; 
public function getAllInfo($sql){ 
$adapter = Zend_Registry::get('db'); 
$flightinformation = $adapter->query($sql); 
return $flightinformation; 
} 
}
