Next and previous

Hi there...

I have a cfm page which searches a database and then uses the query to display results using cfooutput into a number of text fields on the page.

What is the easiest way to provide a NEXT button which would display the next found record in the fields.

thanks for the help.

It gioes something like this.  i do this from memory, so i apologise in advance if i do not have the tags right - ie, i can't remember if it is maxrows or rowcount or maxrecords or whatever, but the basic structure should be enough to give you the idea....

<cfset maxrows=10>

<cfif isdefined('form.startrow')>
  <cfset startrow=form.startrow>
<cfelse>
  <cfset startrow=1>
</cfif>

<cfquery name=list ... ... ...>
  [sql stuff]
</cfquery>

<cfif isdefined('form.next')>
  <cfset startrow = min(startrow+10, list.recordcount-10)>
</cfif>

<cfif isdefined('form.prev')>
  <cfset startrow=max(startrow-10, 1)>
</cfif>
<form action="thisform.cfm" method=post>

<cfoutput>Displaying records #startrow# - #startrow+10# of #list.recordcount#<p></cfoutput>

[table heading]
<cfoutput query=list startrow=#startrow# maxrows=#maxrows#>
  [table stuff]
</cfquery>
<cfif startrow gt 1><input type=submit name=prev value="PREV #maxrows#"></cfif>
<cfif startrow lt list.recordcount><input type=submit name=next value="NEXT #maxrows#"></cfif>
</form>

Hi Richard,

I've also answered this one a few times in this group.  You can find the most recent one at http://www.experts-exchange.com/jsp/qShow.jsp?ta=coldfusion&qid=10310035 

Generally, it's probably best to search through the previously answered questions list before you post a question. You might get your answer a bit quicker and it'll cost you less points. :)

Good Luck,
Rod

Try the following code

You should replace "cfparam name" to your field variables.

<!-- Initialise constants -->
<cfset MaxRows = 10>
<!-- Initialise all fields if they do not exist -->
<cfparam name="start" default="1">
<cfparam name="us_id" default="">
<cfparam name="us_dp_code" default="">
<cfparam name="us_name" default="">
<cfparam name="us_address_line_1" default="">
<cfparam name="us_access" default="">


<!-- What is the next row to start at -->
<cfset PrevStart = Start - MaxRows>
<cfset Nextstart = start + MaxRows>

<!-- Previous Button Code -->
<cfif prevstart GTE 1>
<cfoutput>
<form action="usercreation.cfm" method="post">
<input type="hidden" name="start" value="#PrevStart#">
<input type="hidden" name="us_id" value="#US_ID#">
<input type="hidden" name="us_dp_code" value="#US_DP_CODE#">
<input type="hidden" name="us_name" value="#US_NAME#">
<input type="hidden" name="us_address_Line_1" value="#US_ADDRESS_LINE_1#">
<input type="hidden" name="us_access" value="#US_Access#">
<input type="submit" value="<< Previous #MaxRows# Records">
</form>
</cfoutput>
</cfif>
</td>
<td>
<form action="" method="post">
<input type="submit" value="Update User Record">
</form>
</td>
<td>
<form action="viewall.cfm" method="post">
<input type="submit" value="View All Records">
</form>
</td>
<td>
<!-- Next Button Code -->
<cfoutput>
<form action="usercreation.cfm" method="post">
<input type="hidden" name="start" value="#NextStart#">
<input type="hidden" name="us_id" value="#US_ID#">
<input type="hidden" name="us_dp_code" value="#US_DP_CODE#">
<input type="hidden" name="us_name" value="#US_NAME#">
<input type="hidden" name="us_address_Line_1" value="#US_ADDRESS_LINE_1#">
<input type="hidden" name="us_access" value="#US_Access#">
<input type="submit" value="Next #MaxRows# Records >> ">
</form>
</cfoutput>
</center>
</td>
</tr>
