无法使用php将日期插入到数据库中

Question

我未能将日期值插入到数据库中。它总是显示我"0000-00-00"，我设定的日期结构是日期，它是一个"yyyy-mm-dd"。我试图调试我的查询，除了日期值不能插入到数据库中，一切都可以。我的代码有错吗？

这里是我的代码：

$from = $_POST['from']; 

$newFrom = date("Y-m-d",strtotime($from)); 
// Get default database object 
$db = JFactory::getDBO(); 

// Get a new JDatabaseQuery object 
$query = $db->getQuery(true); 

$tmpIds = array(); 

foreach($courseID as $cId) { 
    $tmpIds[] = $db->quote($cId); 
    //sanitize the input 
} 

$courseID1 = implode(',',$tmpIds); 

// Build the query 
$query->select($db->quoteName('courseid')); 
$query->from($db->quoteName('intake')); 
$query->where($db->quoteName('campusid').'='. $db->quote($campusID)); 

$query->where($db->quoteName('courseid').'IN('.$courseID1.')'); 

// Set the query for the DB oject to execute 
$db->setQuery($query); 
// Get the DB object to load the results as a list of objects 
$results = $db->loadObjectList(); 

if($results){ 

    $query = "UPDATE intake SET startdate = $newFrom WHERE campusid = '$campusID'"; 
    echo "$query"; 
    $db->setQuery($query); 
    $db->query(); 

} 

else{ echo 'Error';} 

}

你错过了周围的日期字符串引号：

$query = "UPDATE intake SET startdate = $newFrom WHERE campusid = '$campusID'"; 

应该是：

$query = "UPDATE intake SET startdate = '$newFrom' WHERE campusid = '$campusID'";
