Question

I know how to use str_replace(), but this is just beyond me. Here’s the input (would come from a MySQL query):

[%] This is a checkbox
[%] I have seen "Star Trek VI: The Voyage Home"
[%] I'm a geek

Here’s how I would like the output rendered:

<label><input type="checkbox" name="requirement[1]" value="1">This is a checkbox</label>
<label><input type="checkbox" name="requirement[2]" value="1">I have seen "Star Trek VI: The Voyage Home"</label>
<label><input type="checkbox" name="requirement[3]" value="1">I'm a geek</label>

Obviously, having the [%] at the beginning of the line would denote it becoming a checkbox as would being on separate lines (unless there’s a better, user-friendly way). If there’s a better way than using str_replace(), I’d love to know.

Thanks in advance!

Answer 1

$lines = explode("\n", $mysql_result_string);
$n = 0;
foreach ($lines as $line) {
    echo str_replace('[%]', '<label><input type="checkbox" name="requirement[' . $n . ']" value="1">', $line) . "</label>";
    $n++;
}

Edit: Yup: example here.
