string validation
Codepage-aware string validation helps validating string length, equality, difference, and regular expression patterns.
Proper string validation means that we also care about the codepage - just think of multibyte characters in UTF-8, checking length or provide a safe regexp needs attention! For this reason you must set the way Clonefish handles codepages using form properties.
Depending on the codepage-related settings your regular expressions may be handled by preg_match, ereg or eregi on the PHP side. Use the PHP/JS regexp settings to define similar regular expressions in JS and PHP even if the regexp syntaxes are different.
<?php
$config = Array(
'element' => Array(
'type' => '...',
// ...further element settings here...
'validation' => Array(
Array(
'type' => 'string',
'required' => 0 | 1, // required or not
'minimum' => '2', // minimum length
'maximum' => '5', // maximum length
'regexp' => '/^[a-zA-Z]{5,10}$/', // regular expression to match
'regexpnot' => '/^[a-zA-Z]{5,10}$/', // regular expression to unmatch
// in several cases the same regexp cannot be used both in JS and PHP,
// so we have separate settings for each.
'jsregexp' => '/^[a-zA-Z]{5,10}$/', // JS regular expression to match
'jsregexpnot' => '/^[a-zA-Z]{5,10}$/', // JS regular expression to unmatch
'phpregexp' => '/^[a-zA-Z]{5,10}$/msUi', // PHP regular expression to match
'phpregexpnot' => '/^[a-zA-Z]{5,10}$/', // PHP regular expression to unmatch
'equals' => 'password2', // equals to another field (eg. two passwords)
'differs' => 'fieldname', // differs from another field
'help' => 'Help message value for this validator only'
)
)
)
);
