zen_nj how to properly use the render="..." syntax when I need to look at AND conditions
Hi folks
Not sure if this is visualforce question or apex question in general. But I wanted to render a section of the page only when certain criteria are met. In this case, the criteria is when two fields in my object have specific value.
In my situation, I am using Case object and also using the case standard controller. And in my visualforce page, I want certain sections to be rendered if say:
field 1 contains any value - field 1 is a multi-picklist field
field 2 to contains a specific text value - field 2 is a text field.
I can get the render logic working when I am basing it off just one of the field:
for example:
<apex:form rendered="{!case.field1__c != null}">
this would work and the section would be rendered depending on if field1 (a multi-picklist field) contained any value.
Also,
<apex:form rendered="{!case.field2__c == 'specific text value'}">
this also work and the section would be rendered when field2 (a text field) contains the specific value.
However, I can't seem to get it working so that the section would be rendered only when both conditions are met.
I tried the following variations below but not seem to be working, can someone shed some light on this please?
<apex:form rendered="{ IF (AND(!case.field1__c != null,!case.field2__c=='specific text value'),true,false}">
<apex:form rendered="{ (!case.field1__c != null) && (!case.field2__c =='specific text value') }">

you've got too many ! in there.
Hi Guys!
In my situation, I am using Opportunity object and also using the Opportunity standard controller. And in my visualforce page, I want certain sections to be rendered if say:
field 1 contains any value - field 1 is a number field
field 2 to contains a specific text value - field 2 is a multi-picklist
However, I can't seem to get it working so that the section would be rendered only when both conditions are met.
I applied the logic you mentioned {! AND(Opportunity.field1 ! >= null, Opportunity.field2__c=='value') }
It is throwing the following error
The value 'null' is not valid for operator '>='
Can anyone please help?
If you are testing for that field 1 is not a blank/null value, then you can just use:
{! AND(Opportunity.field1 ! = null, Opportunity.field2__c=='value') }
Since field 1 is defined as a number field, the only value that can be in it would have to be numeric (and not text).
But if you are testing that field 1 must be a number (and should be >= 0), then you could try:
{! AND(Opportunity.field1 ! >= 0, Opportunity.field2__c=='value') }
