Question

이 같은 foreach 루프가

<?php $current_question = ""; 
    foreach ($question_and_answers as $qa) : ?> 
     <?php $current_question == $qa['current_question']; ?> 
     <?php if($current_question == $current_question) : ?> 
      <input type="text" name="question[]" value="<?php echo $qa['question']; ?>"/> 
     <?php endif; ?> 
<?php endforeach; ?> 

입력 필드를 만들 때마다 루프가 새로운 질문에 안타를 쳤습니다. (질문은 많은 답변을 가질 수 있습니다. . 내가 한 것은 효과가없는 것 같습니다.

배열을 반복하면서 배열을 반복하려고 할 때마다 새 질문을 만날 때마다 값이있는 텍스트 입력이 필요합니다. 문제의

Answer 1

시도해보십시오.

<?php $current_question = ""; 
    foreach ($question_and_answers as $qa) : ?> 
     <?php if($current_question == $qa['current_question']) : ?> 
      <input type="text" name="question[]" value="<?php echo $qa['question']; ?>"/> 
      <?php $current_question = $qa['current_question']; ?> 
     <?php endif; ?> 
<?php endforeach; ?> 

Answer 2

귀하의 코드는 아마 당신은 그런 식으로 작성하기위한 당신의 이유가 있지만 더 나은 모습이 걸릴 수 있습니다 그래서 내가 그것을 다시하게, 매우 이상하다 :

$current_question = ''; 

foreach($questions_and_answers as $qa){ 

    $current_question == $qa['current_question']; 

    if($current_question == $current_question){ ?> 
     <input type="text" name="question[]" value="<?php echo $qa['question']; ?>"/> 
    <? } 

} 

나는 고장의 몇 참조 :

1. $current_question == $qa['current_question']; 아무 것도 수행하지 않고 조건부이며 true 또는 false를 반환하지만 아무 것도 반환하지 않습니다. 나는 당신이 이것을 정의와 섞 었다고 생각한다 : $current_question = $qa['current_question'];
2. $current_question == $current_question;은 항상 동일한 변수이기 때문에 1을 반환 할 것이다.

   $current_question = ''; 
   
   foreach($questions_and_answers as $qa) 
       if($current_question == $qa['current_question']){ ?> 
        <input type="text" name="question[]" value="<?php echo $qa['question']; ?>"/> 
       <? } 
   

   또는 코드에서 :

   이

   <?php $current_question = ""; 
       foreach ($question_and_answers as $qa) : ?> 
        <?php if($current_question == $qa['current_question']) : ?> 
         <input type="text" name="question[]" value="<?php echo $qa['question']; ?>"/> 
        <?php endif; ?> 
   <?php endforeach; ?> 
   

   이 그러나 아직도 이상하다 난 당신이 당신이 찾고있는 무엇을해야 $qa['current_question']

이와 비교하려는 생각 왜냐하면 $current_question을 빈 문자열로 정의하기 때문에 $qa['current_question']이 비어있는 경우에만 조건부가 실행됩니다. 그러나 귀하의 질문은 당신이 정확히 무엇을 의미하는지보기에는 너무 모호합니다.
