[SalesForce] Apex/Visualforce: multiline IF statement in HTML

Can I write a multiline if statement in Apex/Visualforce HTML?

Something like (definitely pseudocode):

<apex if (condition)>
  <strong>This HTML.</strong>
<apex else>
  <strong>This is the false HTML.</strong>
<apex end>

Update

It seems like the answers here don't work, i.e. neither this:

<apex:outputPanel rendered="{!IF(Lead.Credit__c > 0)}">
  <tr>
    <td>Credit</td>
    <td>{!Lead.Credit__c}</td>
  </tr>
</apex:outputPanel>

Nor this work:

<apex:variable var="v" value="1" rendered="{!IF(Lead.Credit__c > 0)}">
  <tr>
    <td>Credit</td>
    <td>{!Lead.Credit__c}</td>
  </tr>
</apex:variable>

Does it have to be a boolean value?

Use like below

<apex:outputtext value="!IF(ISNULL(Eslot.sEvent), 'Free', IF(Eslot.sEvent.Appointment_Type__c == 'Personal', 'Pers', 'Fill'))}"/>

else

<apex:outputPanel rendered = "{! If(m.Name=='sai' ,true,false) }">
</apex:outputPanel>
<apex:outputPanel rendered = "{! If(m.Name=='sam' ,true,false) }">
</apex:outputPanel>
<apex:outputPanel rendered = "{! If(m.Name=='test1' ,true,false) }">
</apex:outputPanel>

Addition to above

If you are using html elements and want to hide based on conditions

<div style= "display: {!If(m.Name=='sai' ,'none','') }">
</div>
<div  style= "display: {! If(m.Name=='sam' ,'none','') }">
</div >
<div  rendered = "display:{! If(m.Name=='test1' ,'none','') }">
</div >

[SalesForce] How to get a list of child objects from parent object using apex

Providing the parent object and child object are both included in the query, the relationship fields are populated and can be used in Apex code.

I'm not sure what you mean by "not via SOQL". You can assign the relationship fields in Apex code but having them automatically set as a side affect of the SOQL keeps the code much simpler.

In static SOQL it would be:

Map<Id, List<SObject>> m = new Map<Id, List<SObject>>();
for (Parent_Object_API_Name__c p : [
        SELECT Id, Name, (SELECT Id, Name FROM Relationship_Name__r)
        FROM Parent_Object_API_Name__c
        ]) {
    m.put(p.Id, p.Relationship_Name__r);
}

and in dynamic SOQL it would be (using SObject.getSObjects):

String relationshipName = 'Relationship_Name__r';
String soql = ''
        + ' SELECT Id, Name, (SELECT Id, Name FROM ' + relationshipName + ')'
        + ' FROM Parent_Object_API_Name__c'
        ;
Map<Id, List<SObject>> m = new Map<Id, List<SObject>>();
for (SObject p : Database.query(soql)) {
    m.put(p.Id, p.getSObjects(relationshipName));
}

Not sure what problem you are hitting.

[SalesForce] How to pass the checkbox value to apex class method from visualforce page

I think you should not use an actionFunction, but rather actionSupport. Your checkbox will look something like this;

<apex:inputCheckbox value="{!myCheckbox}>
    <apex:actionSupport event="onchange" action="{!myApexFunction}" />
</apex:inputCheckbox>

In this case the checkbox will be automatically posted to the controller, so there's no need to pass it as a parameter. For reference; the documentation of the actionSupport element.
