Example: loginform.cfm

The loginform.cfm page consists of the following:

<H2>Please Log In</H2>
<cfoutput>
   <form action="#CGI.script_name#?#CGI.query_string#" method="Post">
      <table>
         <tr>
            <td>username:</td>
            <td><input type="text" name="j_username"></td>
         </tr>
         <tr>
            <td>password:</td>
            <td><input type="password" name="j_password"></td>
         </tr>
      </table>
      <br>
      <input type="submit" value="Log In">
   </form>
</cfoutput>

Reviewing the code

The following table describes the loginform.cfm page CFML code and its function:

Code Description 
<H2>Please Log In</H2>
<cfoutput>
   <form
action="#CGI.script_name#?#CGI.
query_string#"
method="Post">
      <table>
         <tr>
            <td>username:</td>
            <td><input type="text"
               name="j_username"></td>
         </tr>
         <tr>
            <td>password:</td>
            <td><input type="password"
               name="j_password"></td>
         </tr>
      </table>
      <br>
      <input type="submit" value="Login">
   </form>
</cfoutput>

Displays the login form.

 

Constructs the form action attribute from CGI variables, with a ? character preceding the query string variable. This technique works because loginform.cfm is accessed by a cfinclude tag on Application.cfc, so the CGI variables are those for the originally requested page.

 

The form requests a user ID and password and posts the user's input to the page specified by the newurl variable.

Uses the field names j_username and j_password. ColdFusion automatically puts form fields with these values in the cflogin.name and cflogin.password variables inside the cflogin tag.
