Question

嗨frinds我有一个像这样的帖子数据

Array
(
    [m_categoryid] => 81
    [subcat_id_for_cat] => 87
    [title] => test
    [body] => test
    [adtype] => 2
    [1] => iphone
    [2] => xxx
    [7] => yes
    [submit] => Submit ads

其中前5个字段是固定字段转到一个表table_1但是最后3个字段是动态字段，它们继续增加或减少字段并转到另一个表table_2

无法弄清楚如何解决这个问题

Answer 1

尝试使用多维数组

Array
(
    [m_categoryid] => 81
    [subcat_id_for_cat] => 87
    [title] => test
    [body] => test
    [adtype] => 2
    [dynamic] => array(
       [1] => iphone
       [2] => xxx
       [7] => yes
    )
    [submit] => Submit ads
)

然后

foreach($dynamic as $row)

Answer 2

或者如果你不能修改数组和动态数据总是得到数字键

$arr = array
(
    "m_categoryid" => "81",
    "0" => "iphone",
    "2" => "xxx",
    "submit" => "Submit ads"
);

foreach ($arr as $key=>$row)
{
    if(is_numeric($key))
    {
echo "insert table_2\n";
    } else {
echo "insert table_1\n";
    }
}

您可以创建2个数组。在第一个你把前5个元素，在秒中另一个。你可以在桌子上分配正确的数组。

$input = Array (  
"m_categoryid" => 81,  
"subcat_id_for_cat" => 87,  
"title" => "test",  
"body" => "test",  
"adtype" => 2,  
"iphone" => 1,
"submit" => "Submit ads" 
);

$c = count($input); 
$length = $c - 5; 
$first = array_slice($input, 0, 5,true); 
$last = array_slice($input, 5,$length, true);
$headfirst = array();
$valuefirst = array(); 
foreach($first as $key => $value){
    $headfirst[] = $key;
    $valuefirst[] = $value;
}

$this->table->set_heading($headfirst);
$this->table->add_row($valuefirst);
echo $this->table->generate();

$last = array_slice($input, 5,$length, true);
$headlast = array();
$valuelast = array(); 
foreach($last as $key => $value){
    $headlast[] = $key;
    $valuelast[] = $value;
}
$this->table->set_heading($headlast);
$this->table->add_row($valuelast);
echo $this->table->generate();

这就是全部

codeigniter在动态改变列的2表中插入数据
