[SalesForce] Make a button on visualforce update the records in an object

I have a custom object named "O1". It have 5 fields, namely

1.) Address

2.) Name

3.) Email

4.) Phone Number

5.) Age

I have created a custom VF page and shown these fields on that page. Now, I want to assign a save button which will save the data entered by user here into the object "O1".

How can I do so? Is it called anything? I can look it up myself, just need someone to point me in right direction.

thank you

If these are all fields that live directly on your custom object, then you can just use the standard controller on your custom object, and then invoke the standard {!save} function on a commandButton/link/etc

Something like this... (Note, have not attempted to compile code, wrote on the fly):

<apex:page standardController="O1__c">
    <apex:PageBlock>
        <apex:PageBlockSection>
            <apex:form>
                <apex:inputField value="{!O1__c.Name}" />
                <apex:inputField value="{!O1__c.Email__c}" />
                ... etc
                <apex:commandButton value="Save" action="{!save}" />
            </apex:form>
        </apex:PageBlockSection>
    </apex:PageBlock>
</apex:Page>

See the Salesforce Documentation on StandardController Methods for more information on all methods available when using standardController:

[SalesForce] VisualForce- Save data from multiple object

It's almost certainly your exception handling that is hiding/obscuring the issue. As a test, try commenting out the exception handling to see if the actual exception is displayed.

Within your exception handling block you could also log the exception to make it easier to track.

E.g.

try {
    //...
} catch (Exception ex) {
    System.debug(LoggingLevel.Error, 'CustomController.save() Exception: ' + ex);
}

[SalesForce] override Standard Save Button (with a visualforce page) on Standard page of a Custom object

Add a field, hidden, of course, that should be set when a message should be displayed. Then, add a hidden Visualforce page to the layout that should reset the flag and show a message when appropriate. The flag can be set from a trigger.

trigger X on Y (before insert, before update) {
    for(Y r: Trigger.new) {
        r.Flag__c = r.Field__c == 'Some Value';
    }
}

Page:

<apex:page standardcontroller="Y" extensions="yExt" action="{!resetFlag}">
    <script>
    if({!showmessage}) {
        alert("Some informational dialog");
    }
    </script>
</apex:page>

Extension:

public class yExt {
    ApexPages.StandardController c;
    public Boolean showMessage { get; set; }
    public yExt(ApexPages.StandardController ctrl) {
        c = ctrl;
        showMessage = ((Y)ctrl.getRecord()).Flag__c;
    }
    public void resetFlag() {
        ((Y)c.getRecord()).Flag__c = false;
        c.save();
    }
}

Drop this into a page layout with a zero-height frame (will make it effectively invisible), and you've got your message alert.

This is only a very basic framework; you might want to make some adjustments based on your exact requirements.
