CodeIgniter: How can I display single validation error?

Question

If I used this

<?= validation_errors(); ?>

the result is

Username field is required
Password field is required
<textbox for username>
<textbox for password>

what I actually need is to display those errors inline with their element

example:

<textbox for username> Username field is required
<textbox for password> Password field is required

This is covered in the user guide:

Showing Errors Individually

If you prefer to show an error message next to each form field, rather than as a list, you can use the form_error() function.

So if your field name is username, you would use form_error('username').

Important Note: If you use an array as the name of a form field, you must supply it as an array to the function. Example:

<?php echo form_error('options[size]'); ?>

This is a shortcut for $this->form_validation->error(), which you can also use if you desire.

Answer 2

In order to display error individually you should use the function form_error('username'). And for you to get a value of a field being checked, use the function set_value('username').

For these two functions to work, you would have had to, in your controller, set a rule for the 'username' field. Where you specify wich validation rules apply to that field.

<?php echo form_error('username'); ?>
<input type="text" name="username" value="<?php echo set_value('username'); ?>">
