Question

I have PHP radio buttons being generated by the following code:

while($a_row = mysql_fetch_array($answers_result))
    {
        // print each answer choice
        ?>
        <input type='radio' name='question_<?php echo $current_question['id'] ?>'                     
                value='<?php echo $a_row['prompt']?>'><?php echo $a_row['prompt']?>
        <br />

    <?php
    }

I am then defining the user’s choice with this code:

$user_answer = $_POST["question_{$_SESSION['current_question']['id']}"];

However, this isn’t always returning the value, which should be whatever $a_row[‘prompt’] is.. If it is the first radio button in the list, it returns “answer 1”, etc.. It is not getting the correct values from my sql table. Am I doing something wrong in my code that is causing it to not actually get the “value” of each radio button when the user selects it and submits the form?

Answer 1

You need to escape the ‘ ‘ as you start with them

<input type='radio' name='question_<?php echo $current_question[\'id\']; ?>'                     
            value='<?php echo $a_row[\'prompt\'];?>'><?php echo $a_row['prompt'];?>

Also note that your need to finish your PHP command with ; that not the case.

To avoid ‘ ‘ trouble I recompend using ” ” when you know that you will have to add some ‘ ‘ in your code, that way they do not interfere.

<input type='radio' name="question_<?php echo $current_question['id']; ?>"                     
            value="<?php echo $a_row['prompt'];?>"><?php echo $a_row['prompt'];?>
