I have a basic AJAX question. Please note that I have no knowledge in AJAX but a little in CF, so please explain very detailed or even write the necessary code for me - thank you.
I built a database containing 8k images (images are not in the database but this isn't the issue). each image has a couple of attributes. Among them one which I call quality and which can have integer values from 1 to 9. By default I set all values to 5.
I made a query which selects one image at the time (this is actually not of interest) and display all its attributes on a webpage. I would like now that the quality attribute can be changed without firing a form to another page but by just moving a slider (cfslider) to the value the visitor of this page likes.
For the moment I wrote the following:
<cfquery name="myQuery" dbtype="query">
SELECT * FROM myTable
name = "myQuality"
clickToChange = "false"
format = "html"
increment = "1"
max = "9"
min = "1"
tip = "true"
value = "#myQuery.pic_quality#"
vertical = "false"
width = "100">
Do I need to write a cfc or so, which can be called to update the field "pic_quality" in "myTable"
If yes, how? Where to implement AJAX? Puuuuhuhhhh, I have no idea!
Thank you so much for input!
