Hi, When using a Zend_Form, the only way to validate that a input is not left blank is to do $element->setRequired(true); If this is not set and the element is blank, it appears to me that validation is not run on the element. If I do use setRequired(), the element is automatically given the standard NotEmpty validator. The thing is...

Everytime a user posts something containing < or > in a page in my webapp, I get this exception thrown. I don't want to go into the discussion about the smartness of throwing an exception or crashing an entire webapp because somebody entered a character in a textbox, but I am looking for an elegant way to handle this. Trapping the exce...

I am all about using ASP.NET MVC, but one of the areas that I hope gets improved on is Client-Side Validation. I know the most recent version (Preview 5) has a lot of new features for Validation, but they all seem to be after the page has been posted. I have seen an interesting article by Steve Sanderson... using Live Validation, Castl...
I recently read somewhere that writing a regexp to match an email address, taking into account all the variations and possibilities of the standard is extremely hard and is significantly more complicated than what one would initially assume. Can anyone provide some insight as to why that is? Are there any known and proven regexps tha...

Among other text and visual aids on a form submission, post-validation, I'm coloring my input boxes red to signify the interactive area needing attention. On Chrome (and for Google Toolbar users) the auto-fill feature re-colors my input forms yellow. Here's the complex issue: I want auto-complete allowed on my forms, as it speeds users ...
I'm looking for an easy to use, reasonably complete form validation solution for php. I recall using one years ago that used a few tags on the HMTL side then captured the OB to replace them with some pretty serious code. This feels slightly like overkill me, yet I'm not REALLY wanting to go nuts with my own right now. I'm using SMARTY...
I'm looking for best practices for performing strict (whitelist) validation/filtering of user-submitted HTML. Main purpose is to filter out XSS and similar nasties that may be entered via web forms. Secondary purpose is to limit breakage of HTML content entered by non-technical users e.g. via WYSIWYG editor that has an HTML view. I'm ...
I have a form with multiple fields that I'm validating (some with methods added for custom validation) with Jörn Zaeffere's excellent jQuery Validation plugin. How do you circumvent validation with specified submit controls (in other words, fire validation with some submit inputs, but do not fire validation with others)? This would be si...

You could have the validation rules in the database and ...

Hi All, I'm currently in the process of writing a wizard and want to make each page validate before moving onto the next page. I want to prevent the user from progressing by calling the Validate() method on every child control on the page and and stopping navigation if any of them fail.
