PHP 스크립트는 다음과 같습니다 : 그건 정말해야하는 경우

function insertScores(){ 
     $admNo=$this->input->post('admNo'); 
     $term=$this->input->post('term'); 
     //get the post variables from the Form 
     $posted = $this->input->post(); 
     $x = array_keys($posted); 
     foreach($x as $y) { 
      echo $y ." = ". $_POST[$y]."<br/>"; 
      echo "<br>"; 
      //write the sql 
      $form_data=array(
      'admNo' =>$admNo, 
      'subCode'=>$y, 
      'termId'=>$term, 
      'score'=>$_POST[$y]      
      ); 
      print_r($form_data); 
      $this->SaveForm($form_data); 
     }

Answer 1

, 당신은 name 속성에 대해 특정 접두사를 설정 한 다음 키를 시작으로 찾을 수 너의 $_POST 키 중 접두사. 다음과 같은 것이 있습니다 :

<input type="text" 
     name="subject_<?php echo $subjectCode?>" 
     id="<?php echo $subjectName?>" 
     value="<?php echo set_value($subjectCode)?>" /> 

그런 다음 $_POST 배열에서 검색하십시오.

이 코드는 내 문제를 해결

$subjectCode = null; 
foreach (array_keys($_POST) as $index) { 
    if (strpos($index, 'subject_') === 0) { // you found the needed element    
     // get its value and save it in a variable 
     $subjectCode = $_POST[$index]; 
     break; 
    } 
} 

Answer 2

, 나는 subCode은 다음 POST 이름과 비교 DB에 admNo를 사용하여 가져옵니다.

$subjects=$this->subjectModel->get_subjects(); 
foreach($subjects as $subject){ 
    $subCode= $subject->subCode; 
    foreach($_POST as $key => $value){ 
     //print_r($key); 
     //print_r($value); 
     $form_data=array(); 
     if($key == $subCode){ 
      //echo $subCode. "=". $value; 
      //write the sql for insertion into the database 
      $form_data = array(
      'admNo'=>$admNo, 
      'subCode'=>$subCode, 
      'termId'=>$term, 
      'formId'=>$formstudy, 
      'score'=>$value, 
      'year'=>$year  


      ); 
      $this->SaveForm($form_data);  

     } 
    } 
}
