OK, I now have the function working correctly and is simply like this...
<?
function timeToInt($timeVar)
{
$timeVar = strtotime($timeVar);
$minutes = ((idate('H',$timeVar) * 60) + idate('i',$timeVar));
return($minutes);
}
?>
But now I've run into a different snag. The snag I have now is how do I
pass the value of a form field to php without reloading the page? In other
words, how can I mix javascript and php?
What I have is this...
<input type="text" name="duration" value="<?=$duration?>"
onblur="duration_mins.value=<?=timeToInt('?>this.value<?');?>">
duration_mins is another text type form field which needs to show the
minutes that correspond to the HH:MM format in the "duration" field shown
above.
If I hard code the value like this...
<input type="text" name="duration" value="<?=$duration?>"
onblur="duration_mins.value=<?=timeToInt('5:50');?>">
It works fine, but when I do it as I need to, in otherwords to change the
duration_mins value to reflect the duration value, it doesn't even finish
the output of the form. I'm not even sure if you can mix and match
javascript and php in a single function call. If I recall isn't javascript
client side and php server side or shouldn't that make any difference?
Regards and thanks for the help to date.
