我希望在一行数据库表中插入,使用以下php代码(foreach
)后面的值,但是在插入获取以下错误后,我该怎么办?
值:
<div class="column">
<input type="text" name="start_date[1][]" value="1111">
<input type="text" name="end_date[1][]" value="1111">
<input type="text" name="price_change[1][]" value="1111">
</div>
<div class="column">
<input type="text" name="start_date[2][]" value="2222">
<input type="text" name="end_date[2][]" value="2222">
<input type="text" name="price_change[2][]" value="2222">
</div>
<div class="column">
<input type="text" name="start_date[3][]" value="3333">
<input type="text" name="end_date[3][]" value="3333">
<input type="text" name="price_change[3][]" value="3333">
</div>
Php代码:
$residence_ups_input = $this->input->post('start_date');
$residence_upe_input = $this->input->post('end_date');
$residence_upc_input = $this->input->post('price_change');
var_dump($residence_ups_input); // output this is: nobool(false)
$residence_p = array();
foreach ($residence_ups_input as $idx => $name) { //line 134
$residence_p[] = array(
'start_date' => $residence_ups_input[$idx],
'end_date' => $residence_upe_input[$idx],
'price_change' => $residence_upc_input[$idx]
);
}
;
$data = array(
//'name' => $this -> input -> post('name'),
'residence_p' => json_encode($residence_p)
);
$this->db->insert('tour_foreign', $data);
错误:

替换
foreach ($residence_ups_input as $idx => $name) {
与
foreach (get_object_vars($residence_ups_input) as $idx => $name) {
您正在将对象传递给foreach,它需要一个关联数组。从现在开始
json_decode($string, true)
而不是
json_decode($string)
并像这样访问变量:
$var['key'];
而不是
$ VAR-&GT;键
答案 1 :(得分:0)
$residence_ups_input
变量不是数组
使用此代码:
array_push($residence_ups_input,$this->input->post('start_date'));
array_push($residence_upe_input,$this->input->post('end_date'));
array_push($residence_upc_input,$this->input->post('price_change'));
获取值然后使用foreach()

更改所有列:
<div class="column">
<input type="text" name="start_date[1][]" value="1111">
<input type="text" name="end_date[1][]" value="1111">
<input type="text" name="price_change[1][]" value="1111">
</div>
....
为:
<form method="post">
<div class="column">
<input type="text" name="start_date[]" value="1111">
<input type="text" name="end_date[]" value="1111">
<input type="text" name="price_change[]" value="1111">
</div>
....
</form>
