Hi all!
I’m quite new to CI. I’d like to know if there’s a better way to create a custom error message for a specific field for a certain rule?
For example, I have 3 field test1, test2, test3. I want required rule error message for test1 to be woot, test2 to be wargh and test3 to be something else.
I did a few modifications the Validation library(copied it to the application/library folder and modified it there).
function set_custom_message($lang, $field_name, $val = '')
{
$this->custom_error_message[$lang][$field_name] = $val;
}
And modified the run function a little bit
// Did the rule test negatively? If so, grab the error.
if ($result === FALSE)
{
if(array_key_exists($rule, $this->custom_error_message))
{
$custom_error = $this->custom_error_message[$rule];
if(array_key_exists($field, $custom_error))
{
$line = $custom_error[$field];
}
}else{
if ( ! isset($this->_error_messages[$rule]))
{
if (FALSE === ($line = $this->CI->lang->line($rule)))
{
$line = 'Unable to access an error message corresponding to your field name.';
}
}
else
{
$line = $this->_error_messages[$rule];;
}
}
// Build the error message
$mfield = ( ! isset($this->_fields[$field])) ? $field : $this->_fields[$field];
$mparam = ( ! isset($this->_fields[$param])) ? $param : $this->_fields[$param];
$message = sprintf($line, $mfield, $mparam);
// Set the error variable. Example: $this->username_error
$error = $field.'_error';
$this->$error = $this->_error_prefix.$message.$this->_error_suffix;
// Add the error to the error array
$this->_error_array[] = $message;
continue 2;
}
