我想使用cakephp将数据从csv导入到mysql表中 当我运行该函数时，它会在我的表中放置空值，我相信它是我的$ data数组的格式，这是我的代码。
var $name = 'ScWidths';
var $scaffold;
/*
function import() {
$messages = $this->ScWidth->import('scwidths.csv');
$this->set('messages', $messages);
}
* /
function import() {
// to avoid having to tweak the contents of
// $data you should use your db field name as the heading name
// eg: Post.id, Post.title, Post.description
// set the filename to read CSV from
$filename = TMP . 'uploads' . DS . 'Sc_widths' . DS . 'scwidths.csv';
// open the file
$handle = fopen($filename, "r");
// read the 1st row as headings
$header = fgetcsv($handle);
// create a message container
$return = array(
'messages' => array(),
'errors' => array(),
);
// read each data row in the file
$i = 0;
while (($row = fgetcsv($handle)) !== FALSE) {
$i++;
$data = array();
// for each header field
foreach ($header as $k=>$head) {
// get the data field from Model.field
if (strpos($head,'.')!==false) {
$h = explode('.',$head);
#die(debug($h));
$data[$h[0]][$h[1]]=isset($row[$k]) ? $row[$k] : '';
}
// get the data field from field
else {
$data['ScWidth'][$head]=isset($row[$k]) ? $row[$k]: '';
}
}
$data['ScWidth']['section_id']=1;
$this->ScWidth->create();
// success or not :/
if ($this->ScWidth->save($data)) {
echo "success";
}
}
// close the file
fclose($handle);
// return the messages
//return $return;
}
在我的调试点它返回此数组
array(
'ScWidths' => array(
'chainage' => '0'
),
'Left_side' => '3.7'
),
'right_side' => '3.7'
),
'section_id' => (int) 1
)
)
错误日志即时获取，
...无
我相信我的下一个错误是在我的保存方法中。
这是我的数据文件，只是包含。
ScWidths.chainage,ScWidths.Left_side,ScWidths.right_side
0,3.7,3.7
10,3.7,3.7
20,3.7,3.7
30,3.7,3.7
40,3.7,3.7
50,3.7,3.7
60,3.7,3.7
70,3.7,3.7
80,3.7,3.7
更正了我的代码，如果有人需要一个例子，这是100％工作：）
答案 0 :(得分：2)
这一行不正确
$data[$h[0]][$h[1]][$h[2]]=(isset($row[$k])) ? $row[$k] : '';
$h[2]。
当您爆炸标题名称“sc_widths.chainage”（以'。'作为分隔符）时，您将获得
$h[0] = 'sc_widths'; $h[1] = 'chainage'; 你永远不会得到$ h [2]的数据。
所以针对您的特定问题的修复就是放弃$ h [2]：
$data[$h[0]][$h[1]]=(isset($row[$k])) ? $row[$k] : '';
