html form data to cfc

Report · Oct 16, 2008

I've crawled inside and out of the documentation for how to pass html form data to a cfc and display the result (see http://livedocs.adobe.com/coldfusion/8/htmldocs/help.html?content=buildingComponents_15.html) but -- possibly due to "If the CFC returns a result using the cfreturn tag, ColdFusion converts the text to HTML edit format, puts it in a WDDX packet, and includes the packet in the HTML that it returns to the client." -- I cannot find any way to display the results of passing info either by form or URL ( all that happens on form submit is this url http://70.XX.XX.XX:8500/olo/cfc/SearchOwners.cfc?method=getEmp in the address bar and a completely empty screen).

My .CFM FIle:
<h2>Find People</h2>
<form action="../cfc/SearchOwners.cfc?method=getEmp" method="post">
<p>Enter employee's last Name:</p>
<input type="Text" name="lastName">
<input type="Hidden" name="method" value="getEmp">
<input type="Submit" title="Submit Query"><br>
</form>

My .CFC File
<cfcomponent>
<cffunction name="getEmp" access="remote">
<cfargument name="lastName" required="true">
<cfset var empQuery="">
<cfquery name="empQuery" datasource="OLO">
SELECT *
FROM owners
WHERE family_name = '#arguments.lastName#'
</cfquery>
<cfoutput>Results filtered by #arguments.lastName#:</cfoutput><br>
<cfdump var=#empQuery#>
</cffunction>
</cfcomponent>

Yet this invoke cfm works no problem returning results
<body>

<cfinvoke component="olo.cfc.SearchOwners" method="getEmp" returnvariable="qResult">
<cfinvokeargument name="lastName" value="name"/>
</cfinvoke>
</body>

I SERIOUSLY will appreciate anyone who can help . . . . . .

Don't submit to the cfc. Submit to a cfm page that calls the cfc.

Hi,
You should be able to call a cfc function directly from a web browser.

Save the attached sample as "remote_library.cfc", and open it in the browser as "remote_library.cfc?method=form" to see how it works.

Now find out what's different with your function (start with finding out if the datasource is there and working)

cheers,

<cfcomponent>
<cffunction access="remote" name="say_hi" output="Yes">
<cfargument name="fname" default="">
<cfargument name="lname" default="">
<cfargument name="phone" default="">
Hi #fname#,<br>
This is a test for #fname# #lname# with the phone number #phone#.<br>
<br>
<cfdump var="#url#">
</cffunction>

<cffunction access="remote" name="form" output="Yes">
<h1>TEST</h1>
<form action="remote_library.cfc?method=say_hi" method="post">
<input type="Text" name="fname" value="Al">

You need to send the form to cfm template. The one you have invoke argument. Invoke argument sends the data to cfc, not the form.
