codeigniter将多维数组插入数据库
codeigniter将多维数组插入数据库
提问于 2014-09-30 14:35:32
你好，我有这个多维数组，需要插入到数据库表中。到目前为止，我已经想出了这个解决方案，但并不完全有效。我有一个支持动态字段的表单，许多动态字段。我想用这个函数保存那些动态创建的字段。首先，我已经能够创建一个循环来格式化数据。我使用这个循环来格式化数据
$url = str_replace(' ','-',strtolower($this->input->post('title')));
$data = ['business' => [
'title' => $this->input->post('title'),
'URL' => $url,
'category' => $this->input->post('category'),
'region' => $this->input->post('region')
],
'description_' => [
'text' => $this->input->post('description'),
],
'logo_' => [
'blob' => $this->input->post('logo'),
]];
$nyingi = [ 'location_' => ['text' => 'loc_txt','priority' => 'loc_order'],
'photo_' => ['path' => 'p_txt'],
'video_' => ['path' => 'v_txt'],
'product_' => ['p_id' => 'pt_q', 'text' => 'pt_txt', 'expire' => 'pt_xpr', 'title' => 'pt_tt'],
'service_' => ['p_id' => 'st_q', 'text' => 'st_txt', 'expire' => 'st_xpr', 'title' => 'st_tt'],
'hours_' => ['time1' => 't1', 'time2' => 't2', 'type' => 'tt'],
'map_' => ['text' => 'm_txt']
];
foreach($nyingi as $ins => $vl){
foreach($vl as $fld => $box){
$uwazi = $this->input->post($box);
if(is_array($uwazi) && 1<count($uwazi)){
foreach($uwazi as $bb){
$one[$ins][$fld][] = $bb;
}
} elseif(is_array($uwazi) && 1==count($uwazi)) {
print_r($uwazi);
}
}
}
for($g=0;$g<count($one);$g++){
for($h=0;$h<count($one[$g]);$h++){
for($z=0;$z<count($one[$g][$h]);$z++){
//if(array_key_exists($one[$g][$h+1], $one)){
print $one[$g][$h][$z+1];
//}
}
}
}
$data = array_merge($data, $one);上述代码的输出
[location_] => Array
(
[text] => Array
(
[0] => Lemara Main Office
[1] => Themi branch
[2] => Sinoni branch
)
[priority] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
)
[photo_] => Array
(
[path] => Array
(
[0] => lemaraphoto.png
[1] => themiphoto.png
[2] => sinoniphoto.png
)
)
[video_] => Array
(
[path] => Array
(
[0] => lemaravideo.mp4
[1] => themivideo.mp4
[2] => sinonivideo.mp4
)
)
[product_] => Array
(
[p_id] => Array
(
[0] => product photo
[1] => product 3 photo
[2] => Product 2 photo
)
[text] => Array
(
[0] => product desc
[1] => product 3 desc
[2] => product 2 desc
)
[expire] => Array
(
[0] => product expire
[1] => product 3 expire
[2] => Product 2 expire
)
[title] => Array
(
[0] => product
[1] => Product 3
[2] => Product 2
)
)
[service_] => Array
(
[p_id] => Array
(
[0] => Service 2 photo
[1] => service 3 photo
[2] => service photo
)
[text] => Array
(
[0] => service 2 desc
[1] => service 3 desc
[2] => service desc
)
[expire] => Array
(
[0] => Service 2 expire
[1] => service 3 expire
[2] => service expire
)
[title] => Array
(
[0] => Service 2
[1] => service 3
[2] => service
)
)
)我有这个add_bz函数
function add_bz($data){
$this->db->trans_start(); $er=0;
foreach($data as $table => $sql){
if($table==="business"){
$this->db->insert($table, $sql);
$id = $this->db->insert_id();
} else {
array_merge($sql, array('idd' => $id));
$this->db->insert($table, $sql);}
}
$this->db->trans_complete();
if ($this->db->trans_status() === FALSE){print "Transaction Fails";return FALSE;}
return TRUE;
}该函数只允许我以这种格式插入数据。
[[business] => Array
(
[title] => Email Marketing
[URL] => email-marketing
[category] => 3
[region] => 2
)
[description_] => Array
(
[text] => Some desc
)
[logo_] => Array
(
[blob] => mainlogo.png
)
]作为业务，decription_、logo_是db表，其中标题、URL、类别、区域、文本、blob是相应表的db列，其余是去往这些列的数据。
我希望它是如何工作的。例如在location_中
我希望将数组更改为我的工作格式或其他类似的工作格式
location_ => ['text' => [[0] => 'Lemara Main Office'],
'priority' => [[0] => '1']
]
location_ => ['text' => [[1] => 'Themi Office'],
'priority' => [[1] => '2']
]
location_ => ['text' => [[2] => 'Sinoni Office'],
'priority' => [[2] => '3']
]或者像这样
location_ => [0 => [['text' => 'Lemara Main Office'],
['priority' => '1']
],
1 => [['text' => 'Themi Main Office'],
['priority' => '2']
],
2 => [['text' => 'Sinoni Main Office'],
['priority' => '3']
]
],并且还支持许多列，而不仅仅是这两个列。任何帮助我都深表感谢，因为我已经努力了几天才能做到这一点。提前谢谢。

我建议您将数组转换为JSON字符串，然后将其作为文本插入到DB中。JSON可以很好地处理你的多维数据，
