ColdFusion Tutorial
Adding Radio buttons to a form.
All of your input objects in a form must have their own unique name that will be the label that the browser will assign to them when passing the data. The exceptions are radio buttons. Since only one piece of information will be passed from a set of radio buttons, they all get the same name. HTML requires that one of the buttons is selected by default, the one indicated by the CHECKED command. It is important to understand that the browser will send the name and the value of the selected button, not the text that is associated with the button.
We are going to add two Radio buttons to the form.
Radio button for "Man" and for "Female".
The syntax for Radio button:
<input name="m_f_value" type="radio" value="Man">
or
<input name="m_f_value" type="radio" value="Man" checked>
form1.cfm

< form action="form2.cfm" method="post" name="form1">First Name: <input name="first_name" type="text" size="20" maxlength="20">< br>Last Name: <input name="last_name" type="text" size="20" maxlength="20">< br>Man: <input name="m_f_value" type="radio" value="Man" checked>Female <input name="m_f_value" type="radio" value="Female">< br>< select name="country"> <option value="Afghanistan">Afghanistan</option> <option value="Albania">Albania</option> <option value="Bahamas">Bahamas</option> <option value="Belgium">Belgium</option> <option value="Canada">Canada</option> <option value="China" selected>China</option></ select>< br>< input name="upload_person" type="submit" id="upload_person" value="Submit -->"></ form> |
