if ($this->validation->error_string)...

[eluser]EEssam[/eluser]
Hello,

I'm wondering if there's a better way to write the code below in a view:


<?php if ($this->validation->error_string): ?>
<p>The following errors occurred:</p>
&lt;?php echo $this->validation->error_string ?&gt;
&lt;?php endif ?&gt;


Thanks.

I usually do something like this:

Controller

Code:

$data['warning'] = "<p>The following errors occured:</p>\n" . $this->validation->error_string;
$this->load->view('myview', $data);

View

Code:

<?=@$warning ?>

The @ symbol keeps CI/PHP from generating an warning if $warning wasn't set (IE: when there aren't any errors). Its the same as your method really, it just makes the view's source a little more readable.

Supressing errors is more computationally expensive then its worth probably. You could do something like this

Code:

$data['warning'] = ($this->validation->error_string) ? "<p>The following errors occured:</p>\n" . $this->validation->error_string : '';
$this->load->view('myview', $data);
