Are there functions that I can use withing Flow ? eg. substring, length, math functions
I tried to add "@substring('hello world',2,3)" in an email body, the flow just stopped, and email body becomes uneditable afterward,
I tried to use a variable and set it to the above function, then use the variable in the email, it just simply send the whole text
please advice
Thanks !
@manlamcheng I could't also manage to make concat work... I failed to make this expression work and it was driving me crazy:
"@concat(variables('HTMLTable'),'​​<tr> <td>'​​,item()?['Aplicación'],'</td> <td>',item()?['Version_x0020_Name'],'​​</td> <td>',item()?['Version_x0020_Code'],'​​</td> <td">',item()?['Testing_x0020_Level'],'​​</td> <td>',item()?['Acción_x0020__x002f__x0020_Status'],'​​</td> </tr>')"
So finally I tried with "Compose" action block and it worked fine.
I used Compose action, seems working fine
I tried put something like this on an email body, it simply send me the same string
test "@concat('hello','world')"
then I went back into edit the flow, the email body became uneditable and I had to delete the action and re-did it
Hi @manlamcheng,
Yes, we could take use of Workflow Definition Language to work with Microsoft Flow.
Take a look at the following blog:
Using the Azure Logic Apps Workflow Definition Language (WDL) in Microsoft Flow
For the function usage, you could find the function reference through the article below:
