Long story short, I'm working on an application where CRUD is performed against a MySQL database. Everything is working great, except on the updating portion. I have an HTML form that the user submits to the database, and a separate page where a specific record (event) is pulled back into the form and populates the inputs. All of the other inputs are working properly, but my checkbox block is struggling.
Each checkbox input tag has this associated ColdFusion code (cfloop, cfif). The loop determines if the value is included in the list returned from the database and displays "Checked" if true:
<!--Each input has a cfloop and cfif tag to determine checked checkboxes-->
<input
type="checkbox"
id="alumni_relations"
value="Alumni Relations"
name="cboxes"
<cfloop index="foundRecord.event_type" list="#foundRecord.event_type#" delimiters=",">
<cfoutput>
<cfif #foundRecord.event_type# EQ "Alumni Relations">Checked</cfif>
</cfoutput>
</cfloop>
>
<label for="alumni_relations">Alumni Relations</label>
<br>
It works great! But for whatever reason it is only returning "Checked" for the first listed, and last listed item in the list (e.g a list of: Alumni Relations,Athletics,Management Society,Colleges will only return "Checked" for Alumni Relations and Athletics) Here's a picture of that:

I'm thinking it has to do something with the index, but I've scoured the documentation for cfloop and I'm just not figuring it out. Anyone with any help/advice would be much appreciated!

We have a three-panel display in which Panel One shows a list of countries, Panel Two shows a list of organizations, and Panel Three shows a list of aircraft. If you click a country, both the organizations and aircraft are filtered by that country, using IDs for each.
This is all working fine, but the list of aircraft comes from a "linking table" -- each record contains aircraft ID and name, and operator ID and name. Any given type of aircraft can be listed multiple times, depending on how many organizations operate it. For example, "AW159 Wildcat" is listed twice, once for Army Air Corps and once for Royal Navy. The way it works right now, "AW159" is listed in Panel Three twice when the page initially loads.
I would like any given aircraft to be displayed only once on initial page load, regardless of how many times it may be listed in this linking table. But, I want all the "duplicates" available to be shown, if somebody filters on the operating organization.
Is there a way to loop over all the aircraft but somehow hide duplicates of aircraft ID? Or, might there be a larger problem with the way our database is designed? I am open to suggestions. Thank you all very much in advance!
EDIT: sorry for not posting code; here is some. Thanks everybody for all of your help!
1. Query and array population in cfc:
<cfquery name="queryByOperator" datasource="vertipedia">
SELECT view_aircraftbyoperators.aircraftID
, view_aircraftbyoperators.Aircraft
, view_aircraftbyoperators.operatorID
, view_aircraftbyoperators.Operator
, tbl_companies.country
, tbl_companies.companyShortName
FROM view_aircraftbyoperators JOIN tbl_companies
ON tbl_companies.ID = view_aircraftbyoperators.operatorID
ORDER BY Aircraft
</cfquery>
<cfset count = 1>
<cfset aircraftByOperator = arrayNew(2)>
<cfloop query="queryByOperator">
<cfset aircraftByOperator[count][1] = aircraftID>
<cfset aircraftByOperator[count][2] = Aircraft>
<cfset aircraftByOperator[count][3] = operatorID>
<cfset aircraftByOperator[count][4] = Operator>
<cfset aircraftByOperator[count][5] = country>
<cfset count = count+1>
</cfloop>
2. Outputting on page:
<ul>
<cfloop from="1" to="#ArrayLen(aircraftByOperator)#" index="i">
<cfoutput>
<li name="#aircraftByOperator[i][3]#" class="#aircraftByOperator[i][5]#">
<p>
#aircraftByOperator[i][2]#
</p>
</li>
</cfoutput>
</cfloop>
</ul>
[i][1], [i][3] and [i][5] are all IDs. "operatorID" is the one that will change depending on who operates the aircraft. I hope this helps explain what I am trying, and again, many thanks!
Dan Bracuk's comment "Does this mean you are pre-loading all your data into javascript? It might be more efficient to throw some ajax in there and just get what you need when you need it" ended up being the way to go for us. I would like to mark his comment as the answer, but am unable to see how to do that.
For others who may read this post, we
Loaded all of the aircraft initially
When a visitor filters by country and/or organization, a new query is sent via ajax
I was having a hard time formatting the returned data, so I used jQuery's load() to format it and drop it in the proper place in the output panel.
As Dan said, it is very fast and much easier to work with, especially as our database continues to grow.
Thanks Dan!
I had a Query Where i am Getting 14 records and i need to Populate this records in 4 form fields, they are coming as
select id, name, value from mytable
check the attached Screenshot.
I cannot do cfoutput query as it will loop the form fields 14 times,
i tried something like
queryname.name[currentow], but it not worked, checked this URL of cflib http://cflib.org/udf/queryGetRow
but that did not seems to get work. need to populate the value of the name column in the form field
need to know what is the right way
From this comment only,
"honestl my friend, i think i got confused what to ask; I will try to explain again: Auume i have two columns in my table {name & Value}. It has four rows. Now i have to populate the form fields of the rows 1 to 4, which contains the the details from the value column of the table"
I would do this to build my form:
<cfquery name="data" datasource="whatever">
select name, value
from mytable
</cfquery>
<form action="somewhere.cfm" method="post">
<cfoutput query="data">
<input name="name_#name# value="#value#">
</cfoutput>
</form>
Processing the form is outside the scope of the question so I won't do it. However, I will mention some potential problems. If name is a text field, and it's values contain spaces, puncuation marks, etc, your page will crash due to an invalid variable name. If your table has an id field that is either uuid or numeric, that's a better field to use.
Ok, I did it, Here is if someone encounters this, i may not be able to correctly tell what is required. So here is my Solution:
<cfset rsSettings= initial.getSettings()>
<cfloop array="#rsSettings#" index="k">
<cfset settings[k['name']] = k['value']>
</cfloop>
My Query is returning me an array, Using ben's post
http://www.bennadel.com/blog/124-Ask-Ben-Converting-a-Query-to-an-Array.htm
so to fill the form i used like this and it worked
<input type="text" name="pri" class="text" value="<cfoutput>#settings['pri']#</cfoutput>" />
if you guys have better solution, please share
OK. I've done a terrible job of explaining what I'm trying to do. I will try one more time to be more clear.
I have a list of variables that is submitted to a page with a cfquery insert. The variables come from dynamically named form fields, and are captured using a cfloop:
<cfloop list="#form.fieldnames#" index="item">
</cfloop>
What I have are form fields dynamically named, and a value added, as such:
<input type="hidden" name="ticketid_#some_number#" value="#some_quantity#">
For brevity, lets say the form field name is ticketid_6, and the value is 4. This could be a different name and value (for instance, ticketid_3 with a value of 1), or there might be several form fields of similar construct with different names and/or values.
So, on the insert page, I need to insert ticketid_6 4 times (creating 4 separate rows) into my table. So, a row in the database for each dynamically named form field, times the value of each.
I hope that explains it better.
Leigh,
I am still open to your suggestion on the previous post, but I fear I might not have explained my situation clearly enough for you to give your best recommendation. I will re-approach that question after I get this part figured out.
If you need to loop through all your field names and treat each one of those fields as a list you'd need to do two loops to insert each item.
<cfloop list="#form.fieldnames#" index="item"><!--- loop through all the form fields --->
<cfif find('ticketid_',item)><!--- if the form name contains 'ticketid_'. Use findNoCase if you want to ignore case sensitivity --->
<cfloop from="1" to="#form[item]#" index="counter"><!--- loop through the number in form.ticketid_ --->
<cfquery datasource="#dsn#">
INSERT INTO table (fieldname, fieldValue, TicketNum)
VALUES (
<cfqueryparam value="#item#" cfsqltype="cf_sql_varchar">,--fieldName from the form
<cfqueryparam value="#form[item]#" cfsqltype="cf_sql_varchar">--value of the fieldName in the form
<cfqueryparam value="#counter#" cfsqltype="cf_sql_integer">--ticket number being inserted
)
</cfquery>
</cfloop>
</cfif>
</cfloop>
You'll need to do server side validation to verify they haven't entered a non numeric number for the input box, but assuming you've done that this should achieve what you're looking for.
You need to use Evaluate function to get form dynamically input field value
Try this one
<input type="hidden" name="ticketid_#some_number#" value="#some_quantity#">
<cfloop list="#form.fieldnames#" index="item">
<cfoutpuy>Evaluate("ticketid_#item#")</cfoutpuy>
</cfloop>
You need to first bundle your data into an XML structure
<cfsavecontent variable="myFormData">
<cfoutput>
<ul class="xoxo">
<cfloop list="#form.fieldnames#" index="item">
<cfloop list="#form[item]#" index="eachItem">
<li><b>#xmlformat(item)#</b> <var>#xmlformat(eachItem)#</var>
</cfloop>
</cfloop>
</ul>
<cfoutput>
</cfsavecontent>
Then do a single insert
<cfquery>
INSERT INTO table (formData)
VALUES (<cfqueryparam value="#myFormData#" cfsqltype="cf_sql_varchar">)
</cfquery>
When you pull the data, you can
Show it as is, a bulleted list,
Promote to a bunch of rows in a table
Note that the data is inserted as both HTML and XML
I'm totally unused to Cold Fusion, I'd like to know how to handle a multiple CFSELECT, in particular how to know how many rows I've selected and taking them one by one.
Actually I've managed to see all the rows togheter:
<!--- page_a.cfm --->
<cfform name="fooform" ........>
<cfselect query="myquery" name="fornitori" multiple="yes"></cfselect>
<!--- page_b.cfm --->
<cfoutput>#form.fornitori#</cfoutput>
And, if it's not too much, I'd like to know why it's not correct to write:
<!--- page_b.cfm --->
<cfoutput>#fooform.fornitori#</cfoutput>
Since it is a multiple selection list, the options you select will be submitted to page_b.cfm as a comma delimited list. This means you can use list functions to calculate the total items selected and cfloop to iterate through the selections individually. Note, when using "multiple" select lists, if you select nothing the form field will not exist.
<cfparam name="form.fornitori" default="">
<cfoutput>
Total Items Selected = <cfoutput>#listLen(form.fornitori)#</cfoutput>
Individual Selections:<br>
<cfloop list="#form.fornitori#" index="theSelection">
#theSelection#<br>
</cfloop>
</cfoutput>
why it's not correct to write ..
Because FORM refers to a special system structure, not the name of your html form (ie fooform). FORM contains any form fields submitted via method=POST.
#myquery.recordcount#
btw, use cfdump to display anything. you see some really interesting stuff (I'm not sure whether recordcount is in there though)
getting to the elements:
<cfoutput query="queryname">#title#<br />#content#</cfoutput>
inside the cfoutput you have access to the variables of an element.

Why does this not work? My welcome message, it just doesn't show up:
<p>Welcome <cfoutput>#Recordset1.UserID#</cfoutput>.</p>
The session variable on the login page I created is:
<cflock timeout=999 scope="Session" type="Exclusive">
<cfset Session.IDUsers =''>
</cflock>
is this incorrect? On the index page where I'm trying to display my welcome message I have:
<cfquery name="Recordset1" datasource="cfGossip">
SELECT *
FROM users
WHERE users.IDUsers = <cfqueryparam value="#Session.IDUsers#">
</cfquery>
I'm not sure if this works, or is necessary?
If you set the userid stored in the session to be the empty string, when you query on it, you will only get users for whom the id is the empty string, which shouldn't be any of them. Therefore, the query is returning an empty set, and your page is (correctly) not displaying a user id.
How are you initially identifying the user? Are you querying against a database when they log in? Are you storing a cookie? Reading Tarot cards? For this to work, at some point, you have to store the correct userid, probably in the session. To do that, you need to first identify who the user is.
Also, if you are using CF6+, you probably do not need the cflock. It is now used to prevent race conditions, as CF is now thread-safe.
Looks like you're just starting with CF, welcome to the community.
My understanding of your code makes the structure look like the following, if I'm understanding you correctly:
<cfset session.idUsers = '' />
<cfquery datasource = "cfgossip" name = "recordset1">
SELECT * FROM USERS WHERE USERS.ID_USERS = <cfqueryparam cfsqltype = "cf_sql_integer" value = "#session.idUsers# />
</cfquery>
<cfoutput>Welcome #recordset1.userID#</cfoutput>
The reason this doesn't work is because your session.idUsers value is blank. Assuming you have a user in your database with an ID_USERS value of 1, you could change the CFSET to look like and it should return results.
Additionally, while it's great to see you using CFQUERYPARAM, I'd recommend including a CFSQLTYPE attribute in the tag whenever possible to provide an added line of defense against injection attacks. You can check out http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=Tags_p-q_18.html to see the list of available types.
Is there anywhere in your code where you set your session.IDUsers? You initialize it as a blank ''. Coldfusion does not populate it for you. The session scope is a place that will remember things for that user that you put there for a specified period of time inactivity, usually 20 minutes. So hopefully, somewhere before you run your query you have additional logic that fills that in, otherwise you are asking the database for a user named, ''.
This is just a point of style, but the following may work better for you:
<cfset Session.IDUsers =''>
<!--- Do something here to populate Session.IDUsers --->
<!--- Creates a blank query - not necessary, but can reduce errors later --->
<cfset Recordset1 = queryNew("UserID")>
<!--- Populate the query from the database --->
<cfquery name="Recordset1" datasource="cfGossip">
SELECT *
FROM users
WHERE users.IDUsers = <cfqueryparam value="#Session.IDUsers#">
</cfquery>
<!--- If the query has data, use it, otherwise show generic message --->
<cfoutput>
<cfif Recordset1.recordcount>
<p>Welcome #Recordset1.UserID#.</p>
<cfelse>
<p>Welcome new user!</p>
</cfif>
</cfoutput>
<!--- OR since we used queryNew("userID"), we can simplify without throwing an error. ---->
<cfoutput>
<p>Welcome <cfif len(Recordset1.userID)>#Recordset1.userID#.<cfelse>new user!</cfif></p>
</cfoutput>
Putting the cfoutput outside the paragraph block will make it easier if you have additional variables to insert into the text. (but will work either way)
Regardless of all that, unless you forgot to share a bit more of the code, I think the issue is that the session.IDUsers is blank and needs to be populated before the query. I hope this helps!
