Question

I have a text field which the user can enter comma separated list and then php converts it to a drop select list however I want a condition that will show a text input field if only a single value is entered. I tried the code below but it is only returning the select box even with a single entry. How can I achieve this condition?

<?php $listval = explode(",",$vals);
if(is_array($listval)) { ?>

<select name="valuelist">
<?php 
    foreach($listval as $value) {
    echo '<option>'.$value.'</option>';
} ?>
</select>

<?php }else{ ?>

<input type="text" size="10" name="valuelist" value="<?php echo $vals; ?>" />
<?php } ?>

explode will always return an array. So therefor is_array will always be true.
Change your if statement to this

if(sizeof($listval) > 1)
