重新填充文本项值给出错误

Question

我想重新填充文本项，插入后显示空值

<input type="number" id="primaryincome1"  min="1"  max="999" name="noc[]" 
value="<?php echo (!isset($student1['noc'])) ? 0 : $student1['noc'] ?>" >

<input type="number" id="primaryincome2"  min="1"  max="999" name="noc[]" 
value="<?php echo (!isset($student2['noc'])) ? 0 : $student2['noc'] ?>">

<input type="number" id="primaryincome3"  min="1"  max="999" name="noc[]" 
value="<?php echo (!isset($student3['noc'])) ? 0 : $student2['noc'] ?>" >

<input type="number" id="primaryincom4"  min="1"  max="999" name="noc[]" 
value="<?php echo (!isset($student4['noc'])) ? 0 : $student2['noc'] ?>" >

<input type="number" id="primaryincome5"  min="1"  max="999" name="noc[]" 
value="<?php echo (!isset($student5['noc'])) ? 0 : $student2['noc'] ?>" >

<input type="number" id="primaryincome6"  min="1"  max="999" name="noc[]" 
value="<?php echo (!isset($student6['noc'])) ? 0 : $student2['noc'] ?>"

控制器：

$certids = $this->input->post('certid');  
$nocs = $this->input- >post('noc'); 
$result = array();
foreach ($certids as $index=>$certid) 
{
    $result[] = $certid . '_' . $nocs[$index];
}

echo '<pre>';print_r($result);echo '</pre>';

在输入项中进行更改后，它会提供输出：

Array
  (
[0] => 1_2
[1] => 2_2
[2] => 3_2
[3] => 4_2
[4] => 5_2
[5] => 6_2
[6] => 7_
  )

仅插入第一个值。其余值插入为“ 0”； 我该如何解决这个错误？我需要帮助。
