This has got me in a pickle, though I'm sure it's probably fairly easy.

I need to get the hash value from the parent window uri, and insert this into the set\_value() function. Obviously I can't get a hash with PHP, so it has to be javascript.

```
parent.location.hash

```

works but I've no idea how to get it into set\_value().

The following is the code I'm working with (obviously wrong but you get the idea):

```
<label for="appt_start">Start Time</label>
<?php echo form_error('appt_start'); ?>
<br />
<input id="appt_start" type="text" name="appt_start" maxlength="12" 
value="<?php $time = "<script>document.write('parent.location.hash');
</script>"; set_value('appt_start', $time) ;?>" />

```

Thanks!
