In my Smarty 3 template I have this code:
{$a=8.34}
{$b=8.33}
{$a-$b|round:2}
Expected result is: 0.01
But I receive this: 0.0099999999999998
Does anybody know how to fix this?
Smarty2 applied the modifier to the result of the complete expression.
Smarty3 does it just on the direct prepending value.
So in Smarty3 you have to use brackets:
{($a-$b)|round:2}
That should solve it.

I want to access the data of the object that comes as a smarty variable according to the variable I have defined.
I'm actually expecting like {$page->page_meta->description} as I wrote below. But nothing happens. It doesn't give an error. What is the problem?
Ok now I understand what you mean.
{foreach $metas as $meta}
{$page->page_meta->{$meta}}
{/foreach}
PS next time do not insert screenshots like this but write code
I need to use the variable inside the popup tag from Smarty.
I can't declare the var on the server because it's dynamic (originating from a loop).
I tried all the different approaches with the assign tag like
{assign var=title value="$some_loop_var - sitename!"}
or
{assign var="myfield" value=$some_loop_var + "btn_licencee_select"}
Always the printed variable is empty.
Any ideas what I might be doing wrong?
The solution was quite trivial in the end:
If you use a variable inside a Smarty function you need to "escape" it with backticks:
{popup text="`$some_loop_var`_static_part" }
Hope this helps anybody else as well. Took me hours to figure this out...
I'm having some issues with XPath and import.io and I hope you'll be able to help me. :)
The html code:
<a href="page.php?var=12345">
For the moment, I manage to extract the content of the href ( page.php?var=12345 ) with this:
./td[3]/a[1]/#href
Though, I would like to just collect: 12345
substring might be the solution but it does not seem to work on import.io as I use it...
substring(./td[3]/a[1]/#href,13)
Any ideas of what the problem is?
Thank's a lot in advance!
Try using this for the xpath: (Have the field selected as Text)
.//*[#class='oeil']/a/#href
Then use this for your regex:
([^=]*)$
This will get you the ISBN number you are looking for.
import.io only support functions in XPath when they return a node list
Your path expression is fine, but perhaps it should be
substring(./td[3]/a[1]/#href,14)
"Does not seem to work" is not a very clear description of what is wrong. Do you get error messages? Is the output wrong? Do you have any code surrounding the path expression you could show?
You can use substring, but using substring-after() would be even better.
substring-after(/a/#href,'=')
assuming as input the tiny snippet you have shown:
<a href="page.php?var=12345"/>
will select
12345
and taking into account the structure of your input
substring-after(./td[3]/a[1]/#href,'=')
A leading . in a path expression selects only immediate child td nodes of the current context node. I trust you know what you are doing.
I was reading the JMeter documentation and came across this info box about "If Controllers":
No variables are made available to the script when the condition is interpreted as Javascript. If you need access to such variables, then select "Interpret Condition as Variable Expression?" and use a __javaScript() function call. You can then use the objects "vars", "log", "ctx" etc. in the script.
I don't quite follow this. Does this mean if I want access to a "User Defined Parameter" then I can access it only by writing some JavaScript? The example that follows this box then refers to "${COUNT}"
Could someone clarify the usage of the If Controller, maybe with an example or two?
All these answers are wrong! You need to put the variable reference in quotes, like so:
"${my_variable}"=="foo"
You can simply use something like
${my_variable}=='1'
Sometimes JMeter documentation can be confusing :)

The answer here works but has a very bad performance impact when number of threads exceeds 40.
See below for correct and most performing answer:

UNCHECK the CHECKBOX
"Interpret condition as variable expression"
I wasted a couple of hours without unchecking this checkbox. It worked with and without semicolon(;) at the end of the statement. Make sure that you have set the User-Defined Variables before calling the if controller.
All the following variations worked for me in Jakarta Jmeter 1.5
${__javaScript("${HOMEPAGE}"=="Y")}
${__javaScript("${HOMEPAGE}"=="Y")};
"${HOMEPAGE}"=="Y"
"${HOMEPAGE}"=="Y";
If Controller will internally use javascript to evaluate the condition but this can have a performance penalty.
A better option (default one starting from JMeter 4, see https://bz.apache.org/bugzilla/show_bug.cgi?id=61675) is to check "Interpret Condition as Variable Expression?", then in the condition field you have 2 options:
Option 1 : Use a variable that contains true or false. For example If you want to test if last sample was successful, you can use
${JMeterThread.last_sample_ok}
or any variable you want that contains true/false
${myVar}
Option 2 : Use a function (${__jexl3()} is advised) to evaluate an expression that must return true or false.
For example if COUNT is equal to 1:
${__jexl3("${COUNT}"== "1",)}
OR
${__jexl3(${COUNT}== 1,)}
Starting with 4.0, if you don't use the "Interpret Condition as Variable Expression?", a warning in RED will be displayed:

Have tried until found these.
Using the quotes was my solution.
As Gerrie said you need to check your variable
${my_var} == 'value'
But be careful with the 'User Defined Variables'
Note that all the UDV elements in a
test plan - no matter where they are -
are processed at the start.
That basically means that you cannot define 'User Defined Variables' inside an 'If Controller'. Take a look to the 'BeanShell' instead.
Replace:
${my_variable}=='1'
with
"${my_variable}" == "1"
if it's string value pass as below and its performance effective
${__groovy("${key}"=="value")}
I have used ${code_g1}== 200 in condition and it worked for me.
I want to use XPath code in an InfoPath form to sum the data in field12 when field11 is equal to IT. I tried using the following code, but it doesn't work.
number(sum(/descendant-or-self::node()/my:group12[my:field11 = "IT;"]/my:field12))
I suspect this has to do with the multilayering of groups, as shown below. Does anyone know the code that would allow me to get to the data in group12? Thanks in advance for your help.
myfields>group9>group10>group11>group12>field11 field12
Genipro
Looks like:
number(sum(/descendant-or-self::my:group12[my:field11 = 'IT;']/my:field12))
could be right.
decendant-or-self should not be necissary in this case (unless you need the expression to work even if group12 is moved).
This should work fine:
sum(/my:myfields/my:group9/my:group10/my:group11/my:group12[contains(my:field11,'IT')]/my:field12)
It doesn't matter if any of the other groups are repeating either. All group12's will be checked.
