How to select a form component
Designing a form is based on the data format requirement. For example if you want the users to tell about their gender. Here the user will enter one out of the two choices available, so one period button is to be provided for the user to select. Same way one input text box is to be provided for entering name of the joining member. To select a city, user can be given a dropdown listbox showing name of the cities from which user can select.
Based on different data input requirements we can keep different form components or input types.
Here we will understand different types of components used to collect data and their possible use. Before that let us try to understand the basic form structure or syntax.
Our form area starts with <form ..> and ends with </form>. All our input fields are to be located between these two tags. These are two boundaries for the data entry. Here is the basic syntax for the form tag.
Method attribute of the html form
The method parameter takes two values one is GET and other is POST. In GET method values are passed through the address bar or technically speaking they are passed as query string. We should not pass sensitive information this way as through browser history they can be retrieved. Post method submits the data without using the query string.
The action attribute takes the name of the file to which the data to be submitted for further processing. It can be a file in the same
directory or a file in different directory. We have to give proper path information if they are in different directory. Forms can even
submit data to a different web site by using the URL of the site and the particular page by entering the details in action attributes.
For example form can submit data to https://www.mysite.com/my_file.php page for processing the entered data of the visitor.
If the action tag is left blank then the form will submit the data to itself( same file ). In this case we have to keep the form processing
script in the same file.
We can give a name to the form by declaring it through name tag. Like this name='f1'. It is easy to get the value of any entry by using name tag of the form like
Create a form for a member to enter following data.
Sex ( Radio button )
Class ( select from a list of one to ten )
Details about educational background ( textarea )
The Label and input field must be in one line with matching alignment.
Colour of the font and background of the text should be different.
On Submit the form should send data to a different page. ( Form should be at Signup page signup.html and on submit the data should goto signupck.php page )
