I am going through the following code:
<cfset x_dt = LSDateFormat(Now(), 'yyyy-mm-dd') &" "&
LSTimeFormat(Now(), 'HH:mm:ss')>
<cfif VerboseDebug gt 0>x_dt = #x_dt#<BR><cfflush></cfif>
I didn't understand the usage of <cfflush> here. Wondering since I haven't defined interval here, how does it works here?
I read the documentation.
Normally when you run a CF script, the server does not return any output to the client until after all of the CF code has executed. CFFlush allows you to return output as it is becomes available, rather than waiting until the end. Useful in cases where you want to display results incrementally, such as for some sort of progress indicator.

haven't defined interval here, how does it works here?
When you do not specify an interval, CF automatically flushes any new output when you invoke the tag. From the docs:
The first occurrence of this tag on a page sends back the HTML headers
and any other available HTML. Subsequent cfflush tags on the page send
only the output that was generated after the previous flush.
It looks like your code is using that technique for debugging purposes. When that line of code is reached, the server returns that date string to the client if VerboseDebug is enabled.

I use opencart version 2.1.0.1
Everytime I click admin > sales > order, it will pop up "error undefined." By closing that popup window, I can still edit order but cannot delete order (no response).
In my log, there is:
PHP Notice: Undefined variable: order_id in
/var/www/html/opencart2101/system/storage/modification/admin/view/template/sale/order_list.tpl on line 821
The line 821 is:
url: 'index.php?route=extension/openbay/addorderinfo&token=<?php echo $token; ?>&order_id=<?php echo $order_id; ?>&status_id=' + status_id,
However, I haven't installed any openbay related module. Also, line 821 is inside <!-- --> mark. It should have no effect.
Help!
Although this is now an older version of opencart, I still see this being reported a lot around and about.
The problem occurs due to the store front adding the http url rather than the https url to the order. So firstly you need to fix that. If you dont want to read all of my explanation, you can just hit up the bold points :)
Either way BACKUP EVERYTHING actually not really, back up the file you are going to edit and backup your whole database.
open:
catalog/controller/checkout/confirm.php at around line 100
Find:
$order_data['store_url'] = HTTP_SERVER;
Change to:
$order_data['store_url'] = HTTPS_SERVER;
Now you will want to fix your database because for reasons I cannot fathom, the domain name is placed in the order along with the stores id. and when editing orders it is the usage of that directly within your admin order page that throws up the undefined notice. Basically the browser blocks the request because its trying to make an insecure request from a secure page.
Crack open phpmyadmin or whatever database tool you have on hand.
locate the table, default is oc_orders
Browsing the table, look for the column that contains your store url (i cant remember the name off hand, i think its just store_url but it will be obvious anyway. if you are multi store you will need to run the query for each
I am sure somebody can come up with a clever way to automatically convert just the http into https with a single use sql query on the one column, but this works for me.
Run SQL: adjust as appropriate
UPDATE `oc_orders` SET `store_url` = 'https://example.com' WHERE store_id = 0;
So I have a cfscript tag that runs some XML data through but I'm getting an error on one of my executes its getting weird data it cant use, I am trying to find out what this data is however, all of my attempts to cfdump this data have failed miserably. Does anyone know of a way to get a data log from inside cfscript data?
I've tried:
-Ending the script writing the dump and restarting the script
-ending the script writing the dump and aborting
-putting the dump at the end of the cfscript
I'm running out of ideas. Thank you ahead of time!
Here's are my tips:
First, create a UDF in tag format - I call my "sdump":
<cfunction name="sdump">
<cfargument name="anyvar" required="true"/>
<cfdump var="#anyvar#"/>
</cffunction>
Then in your cfscript while debugging you can simply do:
<cfscript>
sdump(myProblemobject);
</cfscript>
That keeps you from having to break your script block all the time. I actually include mine in a CFC library of functions that's loaded in Onrequest.
Second, sometimes cfdump doesn't play nice with complex XML. It's gotten really smart in CF 9 and later, but I remember CF8 not always loving complicated XML. In that case you have to use your noggin.
For example, try using toString() on the XML object itself and dumping it in source as in tmpvar = toString(myXml); This is more useful if you split out the specific node that is causing you problems into it's own little xml object. Then use dump or (if dump fails) try "writeoutput();" - which is made like a cfoutput for cfscript - like so:
<cfscript>
xmlTmp = toString(myXml);
writeoutput(xmlTmp);
</cfscript>
Working your way through the xml attribute by attribute and node by node might be tediuous, but it might be easier than walking your eyballs through the raw XML looking for issues.
Remember too that you can validate your XML document or var using the various isXML() functions native to CF (isXML(), isXMLAttribute() etc.). Not sure what the list looked like in CF8. Good luck - these sort of problems are always trial and error I'm afraid. :)
This could be a stupid questions for some. But its truly important for me.
I know how to switch frames using selenium webdriver.
However, is there a way to download all the page_source of the entire page for all the frames at once.
Instead of switching them again and again?
Could someone please let me know the command if it exists?
If not then please say there is none. And that should answer my question.
Thanks in advance
Webdrivers' getPageSource will return some state in some formatting of the last page the driver was on.
From the (java)docs, but most probably applies to other languages:
getPageSource
java.lang.String getPageSource()
Get the source of the last loaded page. If the page has been modified
after loading (for example, by Javascript) there is no guarantee that
the returned text is that of the modified page. Please consult the
documentation of the particular driver being used to determine whether
the returned text reflects the current state of the page or the text
last sent by the web server. The page source returned is a
representation of the underlying DOM: do not expect it to be formatted
or escaped in the same way as the response sent from the web server.
Think of it as an artist's impression.
Returns:
The source of the current page

I’ve been battling with a bug with cflocation ever since I upgraded from CF9 to CF10. I’ve worked on it a number of times but always give up but today it’s finally annoyed me enough that it’s time to solve the problem (I hope).
Firstly, apologies as I have tried to write a simple test case to reproduce this problem but so far I’ve been unable to reproduce it outside of original code.
I have a multi-step import process that should run overnight. The process is made up of about 10 files that chain together. When calling the process via a scheduled task a URL parameter (scheduledtask) is also passed. If the parameter does not exist, at the end of each step it stops and waits for the user to click a link to the next step. If the parameter does exist it uses cflocation to move to the next step.
Of all the steps, the 2nd one is the most complex and time consuming (data from multiple web service requests that then need joining, cleaning and inserting into a database). It’s this second step that has a problem after moving to CF10. The page seems to work fine as it’s getting to the very bottom of the page where the cflocation tag is but it never fires cflocation. I’ve added in a cfmail tag to email me as the cflocation is being called, which is always sent, but again cflocation doesn’t fire.
It can’t get much more basic than:
<cfif scheduledtask EQ "true">
<cfmail from="xxxxx” to="xxxx” subject="About to call duplicate" type="text/html">
<p>calling duplicate check - scheduledtask</p>
</cfmail>
<cflocation url="importDupCheck.cfm?scheduledtask=true" addtoken="false">
</cfif>
I know that there is a problem with cfflush and cflocation and I’ve already checked for that.
As a test I tried moving the above logic up the page to just after all the data is retrieved by the webservice but before it’s processed and this time the cflocation worked. I thought maybe it’s a timeout problem where the scheduled task engine has given up waiting even though the page is being allowed to fully load. I tried testing this by having a basic file that had:
<cfset sleep(240000)>
* 4 minutes
before it called cflocation but it worked fine.
The other steps in the process are working as expected with cflocation, just not this one. All this code runs fine under CF9, just failing with CF10.
Does anyone has some pointers on where I should be looking?
Regards
Mark
* Update *
So I’ve now worked out how to easily reproduce this in a few lines of code. Turns out it has nothing to do with scheduled tasks.
index.cfm
<h1>Testing cflocation</h1>
<cfloop index="i" from="1" to="7000" ><!--- For me it stops working once the loop goes beyond 6808 rows --->
row <cfoutput>#i#</cfoutput>: abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz0123456789abcdefghijklmnopqrstuvwxyz0123456789<br/>
</cfloop>
<p>Now loading resultpage via cflocation</p>
<cflocation url="resultpage.cfm" addtoken="false">
resultpage.cfm
<h1>Made it!</h1>
<p>Reload the first page</p>
In my testing I found that if I looped 6808 times it works but 6809 times fails. With 7000 records we are only talking about a 36 KB file….why is this failing only in CF10?
One last thing I should note in case it has an impact- everything I do is done via https.
Ok I worked it out
In CF Administrator
Maximum Output Buffer size 1024
After which a flush will occur which will stop cflocation working.
Increase it and it works.
I have no idea why your code as it stands doesn't work, I'm afraid. At a guess, it's down to ColdFusion 10's replacement of the scheduled task engine, and it not liking some vagary of client-side redirects.
However maybe you can bypass the situation anyhow.
ColdFusion 10's scheduler has a concept of chaining tasks, so that when a task finishes, another one is kicked off. You could conceivably revise your scheduler to leverage that instead?
I had a similar issue, but I was using the location() function in a cfscript. But I suspect the same principle applies.
Prior to the location() function, we were calling a function that was not wrapped in <cfsilent> tags. As a result, every line of the function, including loops, was being output as an empty line of HTML. When I viewed the source code, there were over 20,000 lines of empty HTML code. That is probably enough to reach the 1024 kb buffer limit and trigger the flush that aborts the redirect.
By adding <cfsilent> tags to the custom function, I reduced the number of empty lines of HTML to 39, and now the location() function works as expected.
To determine if this is the issue you are having, add abort; (or <cfabort>) just ahead of the location(), then view the source code of the resulting - presumably empty - page.
Have you tried adding CFABORT after CFLOCATION? That's what I always do - as the code after CFLOCATION should not be executed.
If you check the response from the server (using Charles proxy, Fiddler or something similar) you may find something in the HTML/JS that's preventing the redirection.
I'm being forced/payed to work on a Legacy ColdFusion project (I'm an usual C# programmer) and one peculiarity with CF is that they have they're own tags that are supposed to blend with HTML (bad bad decision, IMO, since it just confuses the hell out of me even with the "starts with cf rule).
Besides this, they have the # character to indicate the start of CF "territory" much alike <% in ASP.Net or $ in Spark or so many equivalents. But this only gets parsed if inside a tag.
My question is: Is there a problem with opening one tag in the begining of the file and closing it, against using only when i'm going to use the # character?
To illustrate here's some code:
<cfoutput>
Some text #SomeVar# Some text.<br />
Some Images some other things #AnotherVar#
</cfoutput>
Against:
Some text <cfoutput>#SomeVar#</cfoutput> Some text.<br/>
Some Images some other things <cfoutput>#AnotherVar#</cfoutput>
Granted, this is might seem trivial for small content but i'm talking about a whole page.
Depending on the page contents, either is fine. There may be a performance impact (minor) by putting all of your page inside the CFOUTPUT tag, because the CFML engine needs to parse and scan the contents of the tag for executable code. Outside of the CFOUTPUT tag, the CFML engine can ignore the page as static content.
If you have CSS and HTML code that uses pound signs (for example named anchors or Hex color codes), you need to escape all pound signs (by adding a second one like "##") when within a CFOUTPUT. Because of this, I generally only put the CFOUTPUT around code I specifically want the CF engine to run.
That said, the CFML engine pays a bit of a performance penalty for constantly opening and closing the CFOUTPUT. If you're looping over come content, put the CFOUTPUT around the entire loop, rather than opening and closing it in each iteration of the loop.
Also, if you're having trouble knowing what code is CFML and what isn't, you might want to get a better IDE/editor for CFML like CFEclipse. It color codes the tags and lets you see the difference between CFML and HTML tags immediately. It's open source.
One problem you might find is that cfoutput is often used to display queries and they can not be nested inside of other cfoutput tags. So this will cause a 'Invalid tag nesting configuration' error
<cfoutput>
<cfoutput query="qFriends">
<li>#qFriends.fname# #qFriends.lname#</li>
</cfoutput>
</cfoutput>
It should not be a big issue but be careful using hex-valued colors, you'll need to escape those with an extra #. If it was me, I would try to break down those huge chunks of content into smaller pieces. Let HTML, JS, Flash and CSS do their jobs and use CF for the server side.
If you want to put cfoutput at the beginning and end of the page, you have to use double sign ## for colors value.
