Constructing an Application with Flash Forms from the Ground Up

You can do much more with them than with simple forms

First, we have an input in the Edit panel for the contact's picture called "photo" that gets its value from the cfgrid photo column.

<cfinput type="text" name="photo" label="Photo:"
bind="{contactList.selectedItem.photo}" />

Then, we have a cfformitem that will get its value from the photo field above:

<cfformitem type="html" height="100" width="100"
bind="<p><img src='{photo.text}'/></p>">
</cfformitem>

What we're trying to achieve is for the value of the cfformitem to be <p><img src='picture.jpg'/></p>, a simple html paragraph with an image inside. But the name of the picture changes for each contact so we bind the path to the photo field in the Edit panel by writing the path of the picture between braces: {photo.text}.

If you look at the source code, you'll find a slightly more complex version of the picture's cfformitem bind:

bind="<p><img src='{(photo.text == '' ? 'man.jpg' : photo.text)}' /></p>"

We're using the if-else shorthand statement again to decide whether we want to show the picture of the contact or a default if the contact photo is empty.

Now that you're getting a feeling for how binding works, we'll add the complete contact information next to the picture. In this case, the binding is rather lengthy, so we'll make a variable containing the binding string and put the variable as the value of the attribute:


<cfsavecontent variable="previewBind">
...the contents of the bind...
</cfsavecontent>

<cfformitem type="html" bind="#previewBind#"></cfformitem>
The content of the previewBind variable is:

{(
((fistName.text != "") ? "<b>First Name:</b>\t" + fistName.text:"") +

...plus all the other fields...

((comments.text != "") ?"<br /><b>Comments:</b>\t"+ comments.text : "")
)}
As you can see, we're using the same trick we used for the photo: if the field isn't empty, we show the value; otherwise we don't show anything. We concatenate all the fields with a "+." We also format the field label with bold and add a tab (\t) between the label and the value to align it.

In case you're wondering how we got the picture next to the text, we used layout tags inside Preview panel (bindings explained above omitted for simplicity):


<cfformgroup type="panel" label="Preview">
<cfformgroup type="hbox">
<cfformgroup type="hbox" width="116">
<!--- the picture --->
<cfformitem type="html" height="100" width="100">
</cfformitem>
</cfformgroup>
<cfformgroup type="hbox">
<!--- the complete contact data --->
<cfformitem type="html"></cfformitem>
</cfformgroup>
</cfformgroup>
</cfformgroup>
Step 6 - Styling the Form
Now that all the elements are in place, we'll add some color and styling to the form. In flash forms, the look-and-feel of each element must be defined in the "style" attribute. Many styles defined in outer containers also apply to inner containers and controls.

As you can see in the picture of the application (see Figure 1), we applied colors to the panels. The contact list has an orange background color and the other two are blue. The complete style for the orange (Contacts) panel is:

style="themeColor:##FE7E00; headerColors:##F2CB2A, ##FFE57A;
backgroundColor:##FFE57A; panelBorderStyle:'roundCorners';"

In this style definition there are three properties applied:

themeColor: color;
Instead of using one of the halo themes (haloBlue, haloGreen, haloOrange, haloSilver) that can be applied with the skin attribute (skin="haloBlue"), we used our own custom color. The themeColor property applies the given color to all the form elements just like halo themes do. The advantage is that we can pick any color, not just one of the four standard themes.

headerColors: color1, color2;
The panel header is composed of a linear gradient of two colors that goes from top to bottom. We can change both of these colors with the headerColors property. The bigger the contrast between the two, the more pronounced the gradient will be.

backgroundColor: color;
The background color of the panel can be changed by using this property. Note however that the cfgrid isn't inheriting the background.

GREAT tutorial but how does one bind a cfselect object with the grid? Tried it and it doesn't work. Any ideas?

Great article by great developers. I have just starting using CF7 and thanks to many writers out there, I have developed some impressive forms. Please visit the www.asfusion.com site for more helpful info.

Michael, visit http://www.cfform.com/flashforms/invoke.cfm?objectid=0204C17F-4E22-1671-... for a tutorial on binding grids to selects. Be mindful that when binding to a grid, the bind is both case and type sensitive to the DB columns.

Michael White 07/17/05 07:39:37 PM EDT

Your article was a good introduction to flash forms with multiple panels. I have a question on the Edit panel... what if some of your fields are CFSELECT dropdowns or date fields... having trouble finding working syntax for binding them to the grid.

Loved the article! It has taught me alot. Maybe I am at fault here but I am not able to get any of this to save or edit in a db anyone else having same problem

I'm having a similar problem with getting the source code for this article. The printed version states that the source code can be downloaded at www.cfdj.com. This URL is invalid and not a site maintained by Sys-Con. Any chance the link can be updated so we can view the source code?

Much appreciative.

Hi,

Thank you for the article, I found it very informative, well written and helpfull. I am having difficulties with the save content section. How could one download the source code ?Could it be possible to modify the link to open on the file rather to to another site that does not seem to be CF Dev. Journal ?

Again that you for sharing.
