Serving Images from Blob type in DB
Posted by Chris in ColdFusion on August 31, 2010
So today I needed to get into NNEREN to get images of properties for sale. I have never used the blob field before and certainly never tried recovering images stored in a db like this. Thanks to a combination of a 5 year old article from Good Ole Ben Forta and a forum post on just skins – I came up with the following code… Read the rest of this entry »
CurrentRow just doesn’t stick…
Posted by Chris in ColdFusion on May 21, 2010
Can anyone answer me this… I am trying to loop through a set of records and create form fields to edit each one – using a mass update. However inside the form I need to put a select box of states.
Here is the code -
<cffunction name="showState" hint="I show the state select box" returntype="string" output="yes"> <cfargument name="sState" hint="selected state" default=""> <cfargument name="name" hint="select field name" default="caucus_State"> <cfset var out = ''> <cfsavecontent variable="out"> <select name="#arguments.name#"> <cfloop query="rsGetStates"> <option value="#state_Name#" <cfif arguments.sState EQ state_Name>selected</cfif>>#state_Name#</option> </cfloop> </select> </cfsavecontent> <cfreturn out > </cffunction> <cfoutput query="rsCaucusList"> <td>#CurrentRow#. <input type="hidden" name="caucus_id#CurrentRow#" value="#rsCaucusList.caucus_ID#"> <cfinput name="caucus_name#CurrentRow#" required="yes" message="A caucus name is required for member #CurrentRow#" type="text" value="#rsCaucusList.caucus_Name#"></td> <td align="center">#showState(rsCaucusList.caucus_state,'caucus_State#CurrentRow#')#</td> </cfoutput> asd
here is what is WRONG…
When the form is rendered – the currentRow variable seems to merge . I get the following dump..
| CAUCUSCOUNT | 3 |
| CAUCUS_ID0 | 2,4 |
| CAUCUS_ID1 | 3 |
| CAUCUS_LINK0 | http://www.senate.gov/~xyz/,http://www.senate.gov/~abc/,http://www.senate.gov/~qwe/ |
| CAUCUS_NAME0 | Senator xyz,Senator abc |
| CAUCUS_NAME1 | Senatorqwe |
| CAUCUS_SORTORDER0 | 0,0,0 |
| CAUCUS_STATE0 | Alabama,Alaska |
| CAUCUS_STATE1 | Alabama |
You will note there are only two causus IDs, and caucus names – 0 and 1. Then there is only 1 link, 1 sortorder, and 2 states. Does
Does anyone get it? I am STUMPED!!
Paypal Buy Now Button Hidden Trick!
Did you know that you can add up to 7 custom fields and their values to a buy now button? Using the merchant interface – you can only have 1 custom field. It is named on0 (Oh N Zero) and it’s value is on1 (Oh N One).
However a little bit of digging into the docs tells us this : ( Paypal Integration center – Developer – How To – HTML – Website Payments Standard – Standard Variable Reference)
on1:
Second option field name and label. The os1 variable contains the corresponding value for this option field. For example, if on1 is color then os1 could be blue.
You can specify a maximum of 7 option field names (6 with Subscribe buttons) by incrementing the option name index (on0 through on6).
Did you catch that? Let me repeat it for you -
You can specify a maximum of 7 option field names (6 with Subscribe buttons) by incrementing the option name index (on0 through on6).
All well and good but how do you use it right? Simple – add some new fields to your submit form like this…
<input type=”hidden” name=”on0″ value=”How Cool is this option?”>
<input type=”hidden” name=”on1″ value=”Do you really feel that way?”>
<input type=”hidden” name=”on2″ value=”YourName”>
<input type=”text” name=”os0″ maxlength=”60″ size=”5″>
<input type=”text” name=”os1″ maxlength=”60″ size=”5″>
<input type=”text” name=”os2″ maxlength=”60″ size=”5″>
So what does it do for you? Simple really – it allows you to collect a few more items in the actual paypal transaction instead of processing those items separately.
