Explode строка базы данных и сравнить значение с другой строкой в ​​php

Question

Я застрял в части моего проекта, где мне нужно сравнить введенный флажок, который я получил в моей базе данных с другим значением.

Мне нужно разбить входные данные с помощью взорвать и сравнить каждое из значений, чтобы увидеть, соответствует ли какой-либо из них список входов. Если кто-то из них делает это, я хочу повторить значения тех, которые соответствуют.

Разделение входных данных, но сравнение не работает. Ниже мой код.

  <?php 
      $cou = explode(',' , $row_rsCourse['courses']); 
      foreach($cou as $mark){ 
       $mark1 = $mark."<br>"; 
        } 

       if ($mark1 = $row_rsCourselist['code']){echo $row_rsCourselist['name'];}else {echo "Failed";} 
      ?> 


       /* 
       For example: 
       $row_rsCourse['courses'] = (a,b,d,g,i) 
       $row_rsCourselist['code'] = is a database column which contains letters a - z in different input 
       $row_rsCourselist['name'] = is a database column which contains names from a - z in different inputs e.g (Andre Ben Charlie etc) 
       */

       ?> 

Answer 1

Я использовал «строк» ​​и «строка», так что это более ясно увидеть, что вместо происходит от фактического $ row_rsCourse вы использовали. Это чище и будет легче видеть другим. Вам нужно будет сделать небольшое редактирование, чтобы сделать эту работу, но вы должны получить то, что вам нужно. Помните, что вы используете POST для получения значения флажка для PHP.

<?php 

    // Set the value of your input to a variable 
     $input_value = isset($_POST['your_checkbox_name']); 
    // You also need to set an array of all of the rows in the database that have code, name, course, etc. 
     $rows = your_rows_in_the_database; 
      // for each row in the database that has a code, name, course, etc. 
      foreach($rows as $row){ 
      // If your input value matches with $row['code'] of the current object in the loop 
       if ($input_value == $row['code']) { 
        // Whatever you want to echo out 
        echo $row['name']; 
       } else { 
        echo 'No matches were found'; 
       } 
      } 
?>
