Codeigniter: Submitted form is not showing values?

Form validation is an important part of any application. Take a look at your favorite web application, notice that there are many forms in these web apps, and it is important that they be secure. It is also important that you have rules that should be adhered to; this also helps to keep a layer of security.

We will cover database interaction seperately. Why should I validate my forms? The answer to this question is simple: security.

If you simply left your forms bare, with no validation, and then stored this information directly in a database, you are liable to attack. People can simply place in some SQL code and can see a dump of a part or all of your database. By using form validation and creating rules, you will disallow most, if not all, of these practices from occurring.

By having set validation rules you can limit the types of data being allowed in your forms. Best of all, the Form Validation Library makes it easy to re-populate your form fields and to show individual errors for each field, making the overall end user experience better; which can mean a lot in an environment with many forms. Even if you are building a contact form, it is a good idea to validate your forms to stop people abusing your form.

In this article, we'll go over a Contact Form and how to use the Form Validation Library methods for validation. The Form Validation processes are different for the developers and for users. Read on to see how the user interacts with the forms, as well as how the developer will create the forms.

A form is displayed to the user, who then fills it in and submits it. The Form Validation Library then checks the form against any rules that the developer has set. If an error occurs the library returns these errors and they are shown against the form with the fields re-populated.

This process proceeds until a valid form is submitted. You create a form, along with a dynamic value from a form helper function—this will re-populate the data if needed. You will also display individual or global errors in the form view file.

You set validation rules, which must be adhered to. Then you check to see if the validation process has been run, and if it has not, you load the form view file. We validate the form data using the Form Validation Library to complete tasks such as checking for empty fields, validating the e-mail, and then send the e-mail off.

All of the code shown should be in the index() function of your email controller. We need to load two libraries for our contact form: the Form Validation Library and the Email class. We can do this in one line, by passing an array to the load->library function.

We also need to load two helpers: the email helper and the form helper. We will do this in the same way as we loaded the two libraries in the previous line of code. The next step in using the Form Validation Library is to set the rules for the form.

These rules are set and must be adhered to. The way we set rules is by using the set_rules() function of the Form Validation Library. As you can see, the function accepts three parameters.

The first is the name of the form field that you wish to set the rule for. The second parameter is the name that you wish to be assigned to this, for humans to read. The final parameter is where you pass any validation rules.

After reading some stuff on GE's website I checked the coil and it seemed frozen. Made some adjustments and left for work. Got home and noticed water dripping from the dispensor and opened the freezer to find that everything on the upper half was defrosting including the ice.

I emptied everything but noticed that everything on the bottom was rock solid. I also noticed that the fan in the back was not working. Could this be causing this issue?

Just before I decided to type this, I checked on the freezer and I heard what sounded like water dripping on a hot exaust and the back panel was warm tothe touch which had very small ice dropplets on it before. Also the fridge seems to be working fine but should I keep it on or will I burn something up? Thanks in advance for any help and sorry for the long post!
