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

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:
Checkbox Example Image
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!
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 not sure my title explains this very well. Frankly, I'm not sure how to put it into words, but here goes:
I am capturing variables from dynamically created form fields on another page, that have been submitted to a page containing the code below. So far, everything works as I want it to. I'm getting the dynamically named form fields. Now I need to add the subtotal dollar amounts together to create a grand total. Unfortunately, I can't figure out how to get the individual totals out of the loop so I can do the math for the final number, due to their dynamic nature.
This part of the code below generates the subtotals, and I need to be able to add all of them together to get a grand total, but I can't figure out how:
#dollarformat(val(getticket[item].ticketprice * form[item]))#
Maybe I need to take a different approach...suggestions/help appreciated.
Here's the full code:
<CFLOOP LIST="#form.fieldnames#" INDEX="item">
<cfoutput>
<cfquery datasource="outertixdb" name="getticket[item]">
select * from tickets
where ticketid = '#item#'
</cfquery>
#getticket[item].ticketname#: #dollarformat(getticket[item].ticketprice)# x #form[item]# = #dollarformat(val(getticket[item].ticketprice * form[item]))#<br/>
</cfoutput>
You would need to set the name attribute of your cfquery using the following format:
<cfquery datasource="outertixdb" name="#getticket[item]#">
To handle the total, you would first need a variable before the cfloop
<cfset total = 0 />
Then, inside the loop, you simply add the price of the ticket to the total
<cfset total = total + getticket[item].ticketprice />
Also, you should be using cfqueryparam in your query. You can read more about it here
Lastly, if you do not need all the data in the tickets table, do not use 'select *..', only pull pack the data that you need.
Not sure I completely understand, but it sounds like you are simply trying to look up a bunch of ticket records, by "id". Then display the individual costs, plus a grand total. If that is all your doing, just give the fields the same name: ticketID. For example:
<input name="ticketID" value="1" ...>
<input name="ticketID" value="22" ...>
<input name="ticketID" value="45" ...>
<input name="ticketID" value="16" ...>
Then the values will be submitted as a list ie 1,22,45,16, which you can feed into your query using an IN clause. That lets you grab all of the data in a single query. (Generally you want to avoid running queries within a loop because performing a separate database query for each id generates a lot of unnecessary overhead and degrades performance).
* Change the cfsqltype as needed
SELECT TicketID, TicketPrice
FROM YourTable
WHERE TicketID IN ( <cfquerparam value="#FORM.ticketID#"
list="true"
cfsqltype="cf_sql_integer">
)
UPDATE:
form[item] is the value of the quantity select from the previous page.
That is a confusing naming convention. I would recommend using a slightly more intuitive name like "quantity". Something more descriptive of the contents. You can still use the ticket id to generate unique names, ie quantity_#ticketID#. For example, using the same ticket id's as above:
<input name="quantity_1" ...>
<input name="quantity_22" ...>
<input name="quantity_45" ...>
<input name="quantity_16" ...>
Once you have the results, there are several ways to generate a grand total. The simplest being to initialize a variable before your loop, then increment it as you iterate. Use the query ticket ID to grab the quantity value from the FORM scope:
<cfset grandTotal = 0>
<cfoutput query="yourQuery">
<!--- extract quantity value --->
<cfset currQuantity = FORM["quantity_"& yourQuery.ticketID ]>
... display price ...
<cfset grandTotal += val(yourQuery.ticketPrice * currQuantity )>
</cfoutput>
GrandTotal <cfoutput>#grandTotal#</cfoutput>
I would recommend throwing out the whole dynamically named query thing.
<cfset total = 0>
<CFLOOP LIST="#form.fieldnames#" INDEX="item">
<cfquery datasource="outertixdb" name="getticket">
select * from tickets
where ticketid = <cfqueryparam cfsqltype="cf_sql_varchar" value="#item#">
</cfquery>
<cfset total += getticket.ticketprice />
<cfoutput query="getTicket">
#ticketname#: #dollarformat(ticketprice)# × #form[item]#
= #dollarformat(val(ticketprice * form[item]))#<br/>
</cfoutput>
</cfloop>
Output your total as needed
In my code, I first create the Query Object:
<cfset memberData = QueryNew('slug,pos,firstname,lastname,email') />
<cfset temp = QueryAddRow(memberData, #numMembers#) />
<!--- LOOP POPULATES QUERY OBJECT --->
<cfloop...</cfloop>
I can then verify that it has been populated by running the following (which outputs as expected):
<cfoutput query="memberData">
#slug# - #pos#<br>
</cfoutput>
I then try to query the memberData Query Object and all hell breaks loose. If I run:
<cfquery name="members" dbtype="query">
SELECT slug,pos,firstname,lastname
FROM memberData
WHERE slug = #slug#
</cfquery>
I get this error:
Query Of Queries runtime error.
The select column reference [university] is not a column in any of the tables of the FROM table list.
In the output test mentioned above, I can verify that "university" is one of the values in the slug column. Clearly I'm missing something in my approach, but I'm baffled as to what it might be. Any help would be greatly appreciated!
Query Of Queries runtime error.
The select column reference
[university] is not a column in any of the tables of the FROM table
list
Your error was caused by absence of quotes in where clause and nothing else:
This expression find rows where the value in slug column equals the value in CF slug variable (String):
WHERE slug = '#slug#'
On the other hand this expression means find rows where value in the slug column equals the value contained in the column named in the CF slug variable (String):
WHERE slug = #slug#
The most likely cause of why you needed to change to SELECT * is CF query caching. So changing it back now should solve the problem. And always use <cfqueryparam .../> as suggested by "Al Everett"
Well, it's not quite answering the question asked, but it's close enough for what I needed:
<cfquery name="members" dbtype="query">
SELECT *
FROM memberData
WHERE slug = '#slug#'
</cfquery>
I had tried the wrapping #slug# in single quotes prior to posting with no success, but doing that plus changing the query to SELECT * fixed the issue. For my content, * only adds one more value retrieved, so not really a problem in slowing down the process.
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.
