I don't think the "standard" validations are available in the CE edition.
What surprises me is that you can't define a validation somewhere and attach it to a field. I kind of expected this, since the rest of the system is very well structured (modules, packages, etc..)
I now for instance created a 11-check, this is a very specific check for a dutch bank account number. to get this to work, I did the following (based upon examples I found googling around):
I added the bank account to contacts in studio and after that edited \custom\modules\Contacts\metadata\editviewdefs.php
I added the following snippets:
'includes'=> array(
array('file'=>'custom/modules/Contacts/customJavascript.js')),
array (
0 =>
array(
'customCode' =>
'<input title="Save [Alt+S]" accessKey="S" onclick="this.form.action.value=\'Save\'; return check_custom_data();" type="submit" name="button" value="'.$GLOBALS['app_strings']['LBL_SAVE_BUTTON_LABEL']>',
),
1 =>
array(
'customCode' =>
'<input title="Cancel [Alt+X]" accessKey="X" onclick="this.form.action.value=\'index\'; this.form.module.value=\''.$module_name.'\'; this.form.record.value=\'\';" type="submit" name="button" value="'.$GLOBALS['app_strings']['LBL_CANCEL_BUTTON_LABEL'].'">'
)
),
And in customJavascript.js i placed this code:
function check_custom_data()
{
if (!eleven_check(document.getElementById("bankaccount_c").value)){
alert ('Bank account not valid');
return false;
} else {
return check_form('EditView');
}
function eleven_check(bankaccount) {
bankaccount=bankaccount.replace(/\D/, "");
charcount=bankaccount.length;
var som=0;
for (i=1; i<10; i++) {
getal=bankaccount.charAt(i-1);
som+=getal*(10-i);
}
if (som % 11==0 && charcount==9) {
return true
} else {
return false
}
}
}
This check now works the way I want it to work, but I'm wondering if this is the best way to add a validation. this way of adding a validation doesn't however accommodate PHP validations, for instance, if I want to validate against some data in the database for one or another reason, I would have to use ajax calls to get that done.
