Question

I’m trying to create a several page survey that is saved each time they progress to the next page. If they then leave and go back to the start, all the information is auto-filled in the fields.

First I select all the previously saved data:

$survey = $_GET['survey'];
$query = "SELECT * FROM data WHERE id='{$survey}'";
$result = mysql_query($query);
$row = mysql_fetch_array($result);

Then later on I use a loop to fetch all the questions on a page with information auto-filled if it’s present in the $row array.

$query = "SELECT * FROM questions WHERE id in (1,2,3)";
$result = mysql_query($query);
    while ($items = mysql_fetch_array($result)){
        if($items['type'] == "text"){ 
        $value = $items['name']; ?>
        <p><?php echo $items['question']; ?> <input type="text" id="<?php echo $items['name']; ?>" name="<?php echo $items['name']; ?>" value="<?php echo $row['{$value}']; ?>" /></p>
        <?php }
    }

An example of the tables:

QUESTIONS

id,type,name,question

1,text,first_name,What is your first name?

2,text,last_name, What is your last name?

DATA

id,first_name,last_name

1,John,Doe

Everything seems to be working except for:

value="<?php echo $row['{$value}']; ?>"

Thanks in advance,

Ditch the quotes, they make it a string literal instead of a variable. (brackets probably aren’t necessary either):

value="<?php echo $row[$value]; ?>"
