在 TypoScript 中，如果满足 c1&c2&c3 条件，如何在菜单项旁边显示“新建”？

Question

Here is the code in typo3 7.6.27:

2.NO {
    after = &nbsp;<span class="nouveau">New</span>
    after.if.value.data = date:U
    after.if.isGreaterThan.data = field:f1
    after.if.value.data = field:f2
    after.if.isGreaterThan.data = field:f1
    after.if.value.data = date:U
    after.if.isGreaterThan.data = field:f2
}

Answer 1

You can't add multiple conditions into one if function in typoscript.
Remember: typoscript will be transfered into a php array before it is being evaluated.

In your example your second condition overwrite the first, and the third overwrites any before.

Typoscript has no build in mechanism for logical operators, so you need workarounds like userfunc or cascaded stdWrap

So a possible solution might be:

2.NO {
    after = &nbsp;<span class="nouveau">New</span>
    after.if.value.data = date:U
    after.if.isGreaterThan.data = field:f1
    after.stdWrap.if.value.data = field:f2
    after.stdWrap.if.isGreaterThan.data = field:f1
    after.stdWrap.stdWrap.if.value.data = date:U
    after.stdWrap.stdWrap.if.isGreaterThan.data = field:f2
}

or you use menuprocessors and fluid after you update to a current version of TYPO3, which is very outstanding if you still use TYPO3 7.6.27 which is out of support for two years. (7.6 ELTS is 7.6.40)

In addition to that, if I want to do a else with a similar block of conditions to display "Updated" if it has been updated, is it possible?

There is no else in typoscript condition function.
you could use override or ifempty but in this case I would suggest to use a COA in the after :

2.NO {
   after.cObject = COA
   after.cObject {
       10 = TEXT
       10.value = &nbsp;<span class="nouveau">New</span>
       10 {
           if.value.data = date:U
           if.isGreaterThan.data = field:f1
           stdWrap {
               if.value.data = field:f2
               if.isGreaterThan.data = field:f1
               stdWrap {
                   if.value.data = date:U
                   if.isGreaterThan.data = field:f2
               }
           }
       }
       20 = TEXT
       20.value = &nbsp;<span class="update">Updated</span>
       20 {
           if.value.data = date:U
           if.is???Than.data = field:f1
           stdWrap {
               if.value.data = field:f2
               if.isG???Than.data = field:f1
               stdWrap {
                   if.value.data = date:U
                   if.isG???Than.data = field:f2
               }
           }
       }
    }
}

with appropriate conditions for 20 .
