From the menu I have
<cfset temp =valuelist(GetDeptNum.csedept_name)>
<cfset ChangedElement = ListGetAt(temp, 2)>
<cfset TempToo = ListSetAt(temp, 2, ",")>
<cfdump var=#TempToo#>
<li class="fullChild"><a id="corporate" href="phonelistsearch_test.cfm?corporate" onclick="changeClass('corporate')" >Corporate</a><a class="opener"></a>
<ul>
<cfloop From = "1" To = "#ListLen(temptoo)#" INDEX = "Counter">
<cfoutput><li> #ListGetAt(temptoo, Counter)#
</cfoutput>
</cfloop>
</ul>
</li>
I have a table which I use a filter to search the table, working, see http://jsfiddle.net/45grrk3m/ .
How would I link it to a table so when I click on the plus sign I can choose different choices
and it will only filter those rows in that csedept_name I click?
Both tables GetUsers and GetDeptNum share the csedept_id collumn.
So from the menu dropdown I get the name right now which works GetDeptNum.csedept_name,
but not sure how I can make the connection between the menu and table.
You need to think about how you're generating the table.
Each option in your table should be a hyperlink back to the page (or ajax....) which passes the option selected. Your SQL query would then refine the search, and the table is recreated using the refined resulty

<cfquery datasource = "myDb" name = "compare">
select *
from users
where cnic = #form.cnic#
</cfquery>
<cfif compare.cnic eq form.cnic>
<p> *CNIC already Exists </p>
</cfif>
I think you're misstating the problem. It should be more like,
"How can I show a form to add a record I know is not in the database?"
Please clarify if that is not the case.
Based on your code, I assume there's been a form submission from another page already. You're running a query to see if there is a record in the users table where cnic = #form.cnic#. If there was no previous form submission, then form.cnic wouldn't exist.
<cfquery datasource="myDb" name="compare">
select *
from users
where
cnic = #form.cnic#
</cfquery>
So when this page loads, you've done your "check if a record is already in the database" with the query named compare. Now all you need to do is check if there are 0 records in the query.
<cfif compare.recordcount EQ 0>
<!--- Display form here. ---->
</cfif>
If the query returns any records, then there is at least one record in the database, so no need to show the form or allow it to be submitted.
You can use bellow code in Jquery ajax calling
<cfquery datasource = "myDb" name = "compare">
select *
from users
where cnic = #form.cnic#
</cfquery>
<cfif compare.recordcount GT 0>
<p> *CNIC already Exists </p>
</cfif>
Depending on your database, too, there are other options. MySQL has some features for INSERT ON DUPLICATE KEY UPDATE (https://dev.mysql.com/doc/refman/8.0/en/insert-on-duplicate.html)
In MSSQL you can do:
IF NOT EXISTS (SELECT 1 FROM [users] u WITH (NOLOCK) WHERE cnic = <cfqueryparam cfsqltype="CF_SQL_VARCHAR" value="#form.cnic#")
INSERT INTO [users].....
(My cfsqltype syntax might not be 100% correct, but always use . Always.
Those might give you some other ways to handle your scenario.
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
Basically I want to have each child menu only display on the parent menu ID. But so far, all I can get is all of the child li's connecting to any parent menu I set up.
Here is a diagram to explain how the menu is displaying right now:
Home
About > Employment & Mobile (I only want employment to display)
Services > Employment & Mobile (I only want mobile to display)
Contact
So the queries output the following variables from the database
pg_LinkName
pg_MenuTitle
pg_ParentMenu (the name of the parent menu),
pg_MenuType (a yes/no to say if it is a parent/sub menu),
pg_SubMenu (a yes/no to specify whether the menu is a parent menu or not)
I want to know if there's a way to connect the child to the parent dynamically. eg. If I choose to attach a page to a parent, it only shows on that parent in the drop down.
Here are my queries:
<cfquery name="qry_GetMenu" datasource="#request.dsn#">
SELECT *
FROM tbl_pages
WHERE pg_MenuType = TRUE AND pg_Display = TRUE AND pg_AutoMenu = TRUE AND pg_Horiz_VertMenu = TRUE
ORDER BY pg_sort
</cfquery>
<cfquery name="qry_GetSubMenus" datasource="#request.dsn#">
SELECT *
FROM tbl_pages
WHERE pg_MenuType = FALSE
ORDER BY pg_sort
</cfquery>
<cfquery name="qry_SubMenu" datasource="#request.dsn#">
SELECT *
FROM tbl_pages
WHERE pg_SubMenu = TRUE
ORDER BY pg_sort
</cfquery>
And this is what I have for the menu:
<ul class="menu">
<cfoutput query="qry_GetMenu">
<li <cfif cgi.path_info contains "#pg_LinkName#"> class="current-menu-parent"</cfif>>
#pg_MenuTitle#
<cfif pg_SubMenu gt 0>
<ul class="sub-menu">
<cfloop query="qry_GetSubMenus">
<li>#pg_MenuTitle#</li>
</cfloop>
</ul>
</cfif>
</li>
</cfoutput>
</ul>
If I'm understanding correctly, you only want to display the assigned children under the corresponding parent, and your code is currently displaying the child elements under every parent displayed?
With your current code, you would need to move one of your queries in line
<ul class="menu">
<cfoutput query="qry_GetMenu">
<li <cfif cgi.path_info contains "#pg_LinkName#"> class="current-menu-parent"</cfif>>
#pg_MenuTitle#
<cfif pg_SubMenu gt 0>
<ul class="sub-menu">
<!---moved inline to add additional conditional pg_ParentMenu clause--->
<cfquery name="qry_GetSubMenus" datasource="#request.dsn#">
SELECT * FROM q WHERE pg_MenuType = 0 AND pg_ParentMenu = '#pg_ParentMenu#'
</cfquery>
<cfloop query="qry_GetSubMenus">
<li>#pg_MenuTitle#</li>
</cfloop>
</ul>
</cfif>
</li>
</cfoutput>
This would allow the query to be filtered specifically to the current parent menu as opposed to all parent menus. If it is a huge data set, this will become pretty inefficient.
There are lots of options at that point (perform the loops and assign to another object like an array of structs that has the keys for parent and children, with the children being another array, or re-working the database to make the sub-menus relational, etc.).
Hope that is moving in the right direction.
I'll explain the 'real life' application of this so it's easier to understand.
I'm working on an eCommerce app that has a category structure. It starts at the top level and gradually moves down through subcategories. For example Home > Electronics > TVs > Plasma
I'm using a single page for this, showing the 'home' page if no category is defined, the subcategories if there are any, and finally the products if there are no subcategories.
This all works fine, however when I get to the 2nd part - displaying subcategories, the page is a little empty. Therefore, I'd like to display a selection of products that span all of the subcategories applicable.
This is where I'm struggling - in most cases, there will be a few subcategories. However, I'm not sure how to structure the 'where' query using the results of the previous query (code snippets below for reference).
I don't believe QofQ would be worth exploring, and I've made a vain attempt at doing something with substrings, without success.
Any pointers much appreciated!
<cfquery name="getcategories">
SELECT p.ID AS CategoryID, p.Cat_Name as CategoryName, p.Cat_Shortname, c.ID AS SubCategoryID, c.Cat_Name as SubCategoryName, c.Cat_Shortname AS SubCatShortname
FROM product_categories p LEFT JOIN product_categories c ON p.ID = c.SubcategoryOf
WHERE p.SubcategoryOf = 0
</cfquery>
<cfif IsDefined('url.cat')>
<!--- Look for additional subcategories --->
<cfquery name="getsubcategories">
SELECT *
FROM product_categories
WHERE Subcategoryof='#url.cat#'
</cfquery>
<cfquery name="getproducts">
SELECT *
FROM products
WHERE categoryid='#url.cat#'
ORDER BY RAND()
</cfquery>
</cfif>
Assuming your products table contains a subcategoryID of some kind you can use the following to get a list of sub category IDs from the query getsubcategories:
<cfset subCategoryIDs = valueList(getsubcategories.subCategoryID) >
This will give you a list of all subCategoryIDs. You can the feed this into the getproducts query like so:
<cfquery name="getproducts">
SELECT *
FROM products
WHERE subCategoryID in (<cfqueryparam cfsqltype="cf_sql_integer" value="#subCategoryIDs#" list="true">)
ORDER BY RAND()
</cfquery>
You should always cfqueryparam your query parameters.
If i understand your database structure, this query should return all products in all subcategories.
<cfquery name="getallproducts">
SELECT *
FROM products p LEFT JOIN product_categories pc ON p.categoryID = pc.ID
WHERE pc.Subcategoryof= <cfqueryparam cfsqltype="cf_sql_integer" value="#url.cat#">
</cfquery>
note: you really do want to use cfqueryparam here.
I’m using Coldfusion 9,0,0,251028 on Windows 7 64-bit, with a Microsoft Access 97 database.
The code is for an application that takes a submitted message from a form and posts it to a different page (breakingnews.cfm). The form values are inserted into the "news" table on a database, including the date the message was submitted (mes_dat) and the date it should expire (exp_dat).
On the database, the is_current and display columns have a default value of 0.
The form action is new_process.cfm, which does two things:
1) Does <cfset expdate = createdate(end_year, end_month, end_day)>. End_year, end_month, and end_day are dropdown selectors that set the expiration date. A problem I have had is expdate not being able to be inserted by post_breaking.cfm, but only when it is put online, on my local testing server there seems to be no problem.
2) Includes a template named "post_breaking.cfm", which runs these queries:
<cfquery name="get_init_info" datasource="#db#">
select id
from news
where is_current = 1
</cfquery>
<cfquery name="update_info_1" datasource="#db#">
update news
set is_current = 0, scrollshow = 0
</cfquery>
<cfif get_init_info.recordcount NEQ 0>
<cfquery name="update_info_2" datasource="#db#">
update news
set display = 1
where id = #get_init_info.id#
</cfquery>
</cfif>
<cfquery name="put_in_info" datasource="#db#">
insert into news
(is_current, display, mes_dat,mes_tim,mes_sub,mes_text,scrollshow, exp_dat)
values
(1,0, #createodbcdate(now())#, #createodbctime(now())#, '#subject#', '#message#',1, #expdate#)
</cfquery>
The message is then displayed on breakingnews.cfm if the column is_current on the news table is 1. This is code I have inherited, so I'm not sure how it does it, but the code only allows 5 messages at a time to have is_current = 1.
The part I'm trying to make happen is having a query run when breakingnews.cfm loads that checks if exp_dat is between now() and mes_dat to set is_current to 1, while still maintaining only 5 items having an is_current of 1.
When breakingnews.cfm is accessed it runs these queries:
<cfquery name="get_info" datasource="#db#">
select *
from news
where
<cfif not isdefined("id")>
is_current = 1
<cfelse>
id = #id#
</cfif>
order by mes_dat desc, mes_tim desc
</cfquery>
<cfquery name="add_exp" datasource="#db#">
UPDATE news
SET is_current = 1
WHERE now() BETWEEN mes_dat AND exp_dat
</cfquery>
<cfquery name="remove_exp" datasource="#db#">
UPDATE news
SET is_current = 0
WHERE now() NOT BETWEEN mes_dat AND exp_dat
</cfquery>
This will cause the messages that have an exp_dat between now() and mes_dat to be displayed and otherwise not display on breakingnews.cfm.
However, when a new message is submitted, upon accessing breakingnews.cfm the first time, only the newly submitted message is displayed.
If the page is refreshed, the messages that were filtered correctly will be displayed under the new message, but there will now be six items displaying on the page when there should only be five.
How can I get the correct amount of messages, and have them display the first time without needing a refresh?
I've gotten advice to replace the get_init_info query with
<cfquery name="get_init_info" datasource="#db#">
select id
from news
where exp_dat > now()
</cfquery>
but that caused all other rows in is_current and scrollshow to be changed to 0 after creating a new message (though the new message's scrollshow and is_current are 1).
My fist thought is to change how the system gets the news to display, but since you sppear not to have control of that, here's my suggestion. Please bear in mind that I've never used Access, so I'm using MS-SQ syntax.
Get the ids of the 5 items you want
select top 5 id
from bews
where exp_date > #createodbcdate(now)#
and display = 1
Now, set display = 0 on all items.
Finally, re-display the ids you found earlier.
update news
set display = 1
where id in #valuelist(query, "id")
