Field validation

Hi Chris,

My question is, are there any out of the box validation methods, like ‘no_html’, “only alpanumeric”, “url” , etc. that can be set while adding Settings Fields?

The framework does not provide such methods and you need to code to sanitize/validate those passed field values.

If not, than are there any ways to use the above mentioned validation_ function to validate more than one field?

Yes. I’ve posted a simple demo plugin for fields validation on Gist. It should be straightforward. See: https://gist.github.com/michaeluno/11385830

Ok. I checked it however I have problems with error messages.

When a field fails validation I set !$bVerified to false and add an appropriate message to the array aError like that:
$aErrors[‘rest_general_texts_section’][‘rest_opening_hours’] = ‘Error msg txt’;

At the end of validation function I check if there are any errors and run this: $this->setFieldErrors( $aErrors );

The problem is that when there are more than 1 error only the first one gets an appropriate Error message in the admin.

Am I doing anything wrong or is this a bug?

Thank you for your help. I really appreciate it.

I’ve updated the post on Gist to demonstrate multiple field error messages. You can see how they are set.

Yup. This is what I was doing before. I’m sending you my plugin that uses your framework so that you might try to reproduce the problem > https://dl.dropboxusercontent.com/u/16604210/cp-extra-admin-pages.zip

All my code is in cp-extra-admin-pages.php. I’ts nicely formatted and commented so you won’t get lost. I’ve modified line 23 so that it uses capability that you have on your installation (I’m using a custom capability).

After installing the plugin you will see a new admin page under Appearance menu. Data in all the fields in the first tab is validated. You may want to put in a few of those fields a “*” character to see (or not) the error messages.

They should show up above all the fields but in my case they show up only above the first one. I double and tripple checked the regex expressions and they are good. If you don’t believe me you might want to put “true” instead of them in the “if” checks.

I hope I’m not wasting your time and this is a bug that I’ve encountered.

Have a nice day,
Chris

Hi Chris,

You have typos in variable names in the validation callback method on line #272, #278 etc.

if( isset( $NewInput['rest_seo_name']) ){

$NewInput should match the variable name set in the parameter.

Though you are using $sNewInput. I suggest you change it to $aNewInput as the passed data is an array. The s prefix implies that the variable is a string whereas the a prefix is for arrays. The validation_{instantiated class name}_{section id}_{field id} filter receives the value as a string while the other validation filters receive the values in an array.

Hope it helps!

Wow. Everything’s fine now. Thank you and I appologize for wasting your time. I spent a few hours checking all the vars and thought I checked everything. You’ve been a great help.

Glad it helped!
