Achilles21 Pass Values from VisualForce Page to Custom Controller
Hi ,
I am new to VF and Apex Development and creating a sample application .
My requirements are as below .
- have to create a simple flight booking application where the user will select Source and Destination from the picklists on the VF page .
- Based on the user's selection , a SOQL needs to run on Apex Controller and return results on VF page that match the criteria.
- I am trying getter method but It is accepting only Custom Object data type . getting various errors .
Question :
Can I be enlighten on how picklist values be sent to controller that can be used as a string , which later can be used in a where clause !!
Hi,
Thanks a lot for the reply , soon as I posted this query i got a solution for it as well .
Below is the code
------------VF-----------------
<apex:page controller="myControl">
<apex:form >
<apex:selectList value="{!main}" multiselect="false" size="1">
<apex:selectOptions value="{!names}"/>
</apex:selectList><p/>
<apex:commandButton value="Test" action="{!test}" rerender="out" />
</apex:form>
<apex:outputPanel id="out">
<apex:dataTable value="{!mains}" var="m" cellPadding="4" border="1">
<apex:column >
<apex:facet name="header">Flight No.</apex:facet>
{!m.Flight_No__c}
</apex:column>
n>
</apex:dataTable>
</apex:outputPanel>
</apex:page>
-----------------Controller--------------------
public class myControl{
String src;
List<Flight_db__C> result;
public PageReference test() {
result = (List<Flight_db__c>)[select f.Flight_No__c from Flight_db__c f where f.leaving_from__c = :src];
return null;
}
public List<SelectOption> getNames() {
List<SelectOption> options = new List<SelectOption>();
for(Flight_db__C f : [SELECT leaving_from__c from Flight_db__C])
options.add(new SelectOption(f.Leaving_from__C,f.leaving_from__C));
return options;
}
public String getMain(){
return src;
}
public List<Flight_db__c> getMains(){
return result;
}
public String setMain(String src){
this.src=src ;
return null;
}
}

Hi,
it would have been better if you would have provided the code that you have written.
Although, following is what i can suggest from my understanding for your problem.
Your apex code would be something like this
List<city__c> lstCities = new List<city__c>();
String selectedCity {get; set;}
.
.
.
Provide the values to the list through constructor
//getter
public List<city__c> getlstCities(){
return this.lstCities;
}
Here goes your VF
<apex:selectList value="{!selectedCity">
<apex:selectOptions value="{!lstCities}"/>
</apex:selectList>
I guess this will give you an idea..
