Updating multiple files with one click

Hello everyone:
I am designing a web photo album where users can upload and see their pictures. Each thumbnail picture will have a checkbok and there will be a button (delete and email). I want the application to delete or email all the selected pictures with a single button click. Does anybody know how to handle this?
I know how to delete one picture at a time(e.g. delete.cfm?photoID=#thisID#); but not multiple pictures at once.

Thanks,
machito

Give each checkbox a unique value (the image name or image path probably). When you submit the form, all of the values that were checked should post to the action page as a comma-delimited list. Loop over that list and for each image do whatever you want.

Hello Kiteless:
The problem is I am looping through the query RecordCount. Do I have to assign a name for each file's checkbox?.
e.g.

<cfoutput query="getImages">
<img src = "#myDir##getImages.ImageName#">
<input type="checkbox" value="#imageID#">
</cfoutput>

I don't know in advance the number of images in the database. Thus, I cannot predict the number of checkboxes needed.

Thanks,

<cfoutput query="getImages">
<img src = "#myDir##getImages.ImageName#">
<input type="checkbox" name="imageChooser" value="#imageID#">
</cfoutput>

You don't need to predict how many checkboxes you need...they all must have the same name, only the values are different.

i belive i can answer your question, when i was making my shopping cart i had a similar problem because i wanted people to be able to edit their contents from the view cart level and thats a bit complicated to do. so here is my explenation in short...

ok this is a sloppy version of how i would do it.

This is for your display page:

<input size="1" type="hidden" name="numberofforms" value="<cfoutput>#getImages.recordcount#</cfoutput>">
<cfset formnumber = 1>
<cfoutput query="getImages">
<input size="1" type="hidden" name="ID#formnumber#" value="#ID#">
<img src = "#myDir##getImages.ImageName#">
<input type="checkbox" name="imageChooser#formnumber#" value="1">
<cfset formnumber = #formnumber# + 1>
</cfoutput>


This is for your action page:
(example is if you want to delete images from a database)

<cfloop index="loopcount" from="1" to="#FORM.numberofforms#">
<cfset variables.imageChooser="form.imageChooser#Evaluate(LoopCount)#">
<cfset variables.imageChooser="#Evaluate(variables.imageChooser)#">
<cfset variables.ID="form.ID#Evaluate(LoopCount)#">
<cfset variables.ID="#Evaluate(variables.ID)#">
<cfquery name="picturedelete" datasource="#datasourcename#" blockfactor="100">
DELETE FROM getImages
WHERE ID = #variables.ID#
</cfquery>
</cfloop>



now there may be better ways to do it or even ways to better that code but i found thats the easiest way to do it.
let me know if it works
