标签: php mysql json

我正在尝试从mysql数据库中提取数据以创建一个json文件,以便与timelinejs时间轴一起使用。问题是json文件必须以某种方式格式化。我已经创建了以下代码来正确格式化json,但它只从我的数据库中拉出一个条目(特别是最后一个条目)。我们非常感谢您提供的任何帮助!

<?php
$link = mysql_pconnect("localhost", "root", "********") or die("Could not connect");
mysql_select_db("php_test") or die("Could not select database");
$rs = mysql_query("SELECT * FROM timelinetest");
while($row = mysql_fetch_array($rs, MYSQL_ASSOC)) 
    $object = array
    ('timeline'=>
        array(
        'headline'=>'Georgia History Title Page', 
        'type'=>'default', 
        'text'=> 'Testing Overview', 
        'startDate'=>'1700', 
        'asset'=>array('media'=>'titlepagemedia', 'credit'=>'titlepagecredit', 'caption'=>'titlepagecaption'), 
        'date'=>array(array('startDate'=>($row['startDate']), 'endDate'=>($row['endDate']), 'headline'=>($row[        'headline']), 'text'=>($row['text']), 'tag'=>'', 'asset'=>array('media'=>($row['media']), 'credit'=>($row[        'credit']), 'caption'=>($row['caption']))), ), 
        'era'=>array(array('startDate'=>'', 'endDate'=>'', 'headline'=>'', 'text'=>'', 'tag'=>'')) 
        )
    );

$json = json_encode($object);
file_put_contents("testing.json", $json);
?>

                    embed_id:   'my-timeline'

            });

在while循环中,您将结果向量$row的内容分配(=覆盖)到同一个(奇异!)对象$object。不熟悉TimelineJS我假设你需要在$object['timeline']中建立一个你可以用

做的数组
while($row = mysql_fetch_array($rs, MYSQL_ASSOC)) {
    $object['timeline'][]=array(
        'headline'=>'Georgia History Title Page', 
        'type'=>'default', 
        'text'=> 'Testing Overview', 
        'startDate'=>'1700', 
        'asset'=>array('media'=>'titlepagemedia', 'credit'=>'titlepagecredit', 'caption'=>'titlepagecaption'), 
        'date'=>array(array(
            'startDate'=>($row['startDate']),
            'endDate'=>($row['endDate']), 
            'headline'=>($row['headline']),
            'text'=>($row['text']),
            'tag'=>'',
            'asset'=>array('media'=>($row['media']),
            'credit'=>($row['credit']),
            'caption'=>($row['caption'])))), 
        'era'=>array(array('startDate'=>'', 'endDate'=>'', 'headline'=>'', 'text'=>'', 'tag'=>'')) 
        );
}

这与array_push($object['timeline'], ...)基本相同,它会将每个结果行的数据附加到'timeline'中的数组$object

修改

现在循环将填充date内的数组era$object['timeline'](尽管era中没有真实数据):

$object=array('timeline'=>array(
    'headline'=>'Georgia History Title Page', 
    'type'=>'default', 
    'text'=> 'Testing Overview', 
    'startDate'=>'1700', 
    'asset'=>array('media'=>'titlepagemedia', 'credit'=>'titlepagecredit', 'caption'=>'titlepagecaption'), 
    'date'=>array(),'era'=>array()
));

while($row = mysql_fetch_array($rs, MYSQL_ASSOC)) {
    $object['timeline']['date'][]=array(
            'startDate'=>($row['startDate']),
            'endDate'=>($row['endDate']), 
            'headline'=>($row['headline']),
            'text'=>($row['text']),
            'tag'=>'',
            'asset'=>array('media'=>($row['media']),
            'credit'=>($row['credit']),
            'caption'=>($row['caption']))); 
    $object['timeline']['era'][]=array('startDate'=>'', 'endDate'=>'', 'headline'=>'', 'text'=>'', 'tag'=>'');

}

也许这有帮助?
