[RESOLVED] Error Checking - Zero Values

[obrienkev]

Hi all,

If the user selects 00 from the below option then this code sees it as an error. How can I get it to allow 00?

Thanks.

if((!$hr_start) || ($hr_start == "0") || (!$min_start) || ($min_start == "0"))
{
$error_message['time_start'] ='<p>Please Select a Time</p>';
}

<option value="0">Minute</option>
<option value="00">00</option>

change this

<option value="0">Minute</option>
<option value="00">00</option>

to

<option value="zero">Minute</option>
<option value="00">00</option>

and then check for the word zero in your if statement

change your == to === to do a strict match (=== means identical where == just means equal).

Here's a quick test to show the difference in this case:

php > $start = '00';
php > 
php > echo $start == '0' ? 'true' : 'false';
true
php > echo $start === '0' ? 'true' : 'false';
false
php >
