Question

What I want to do is to create a feature that creates fields based on what the user selects

For example;

<select name="ex">  
<option selected="selected" value="1">1</option>  
<option value="2">2</option>  
<option value="3">3</option>  
<option value="4">4</option>  
<option value="5">5</option>  
</select>

If the user selected 4, I want to be able to display 4 input fields

My question was, how would I construct a query that would do this?

I rattled my brain and all I could come up with was

if($ex='4') {
<input type="text" name="field4">
<input type="text" name="field4">
<input type="text" name="field4">
<input type="text" name="field4">
}

But there has to be an easier way of displaying them. Any ideas?

Answer 1

If would be easier if you use for loop , like as follows :

for($i=1;i<=$ex;$i++){
 echo "<input type='text' name='field4[]'>";
}

I hope it helps.
