Hi
I've built a form so that the questions generate automatically. I set the number of questions into $numQuestions, I put the questions in an array called $questions, then used a typical for loop to create the questions in an HTML table.
It works fine. The purpose of this is because I'm building many forms with similar structure, but different questions and this saves a great deal of time.
Here's where I'm getting stumped:
When a user fills out the form and submits it, the results are sent to us as well as to their email address. I need to create a similar for loop that can generate the questions and the user's answers in the form email that is sent. The body of the email is the value of the $email_body variable.
So, is there a way to assign the output of a for loop to the value of a variable?
Many thanks,
Andy

Code: Select all
for ($i = 1; $i <= $numQuestions; $i++) {
echo '<tr>
<td align="left" valign="top" border="0">
<p>'.$questions[$i].'</p>
<textarea rows="5" cols="53" id="data'.$i.'" name="data'.$i.'">'.$_POST['data'.$i].'</textarea>
</td>
</tr>';
