I just noticed that in our order check out process that a user can enter a 100+ character zip code(after looking at the design of the MYSQL table I think they can enter up to 255 characters) and the system will accept that zip code. I would expect that their would be a validation process designed into the software but I guess not. How can I add a validation for a zip code?
I would appreciate any comments please...
Solved! Go to Solution.
You can set a vaidation, following this process : open Customers > Attributes > Customer adress attributes
Then select your zip code field, and on the field configuration, you can define input validation, min and max length, as well as a validation that you can define separately as a RegEx if you need more detailled validation rule.
Seem that you use Community version. You can take a look the validation js file: <Magento_Root>/js/prototype/validation.js. As we can see, there are many exist validation classes, we can use them or add a new custom validation class. Magento validation bases on the html classes, so we need to add a custom class to our html inputs and add a custom validation script to global Magento validation object.
For example, I use rwd package and enable Guest Checkout. I'm going to add the class for validating the length of zip code.
And, find zip code input to add validate-zip-code-range
<div class="input-box"> <input type="text" title="<?php echo $this->quoteEscape($this->__('Zip/Postal Code')) ?>" name="billing[postcode]" id="billing:postcode" value="<?php echo $this->escapeHtml($this->getAddress()->getPostcode()) ?>" class="input-text validate-zip-code-range validate-zip-international <?php echo $this->helper('customer/address')->getAttributeValidationClass('postcode') ?>" /> </div>
Unable o find Customer > Attributes...I t might be because of the template or version of Magento?
Community edition, Ultimo 1.11.2 Template.
I found Configuration, Customer..but nothing related to attributers.
Thank you for the suggestion.
I am reviewing your suggestion and I have found what looks to be the same file, it does have some validation scripts added but nothing for zip codes, it pretty much only has "required filed" only. I think this may be the solution. I'll do some testing.
