Inserting records into custom object using Visualforce page

Hi, In this scenario we have explained about how to insert records in custom object using custom controller in vf page. Here we used apex:commandbutton and inputtext for inserting records into custom object.

Apex Controller

public  with sharing class CustomObjInsert {    
    public String phone   {get;set;}    
    public String country {get;set;}    
    public String city    {get;set;}    
    public String name    {get;set;} 
    
    public PageReference ObjInsert() {
        Student__c objins = new Student__c();
        objins.name=name;
        objins.city__c=city;
        objins.country__c=country;
        objins.phone__c=phone;
        insert objins;
        
        pagereference ref = new pagereference('/apex/CustomObjInsert');
        ref.setredirect(true);
        return ref;
    }
}

Vf Page

<apex:page sidebar="false"  controller="CustomObjInsert">
    <apex:form >
        <div style="border:1px solid; width:280px;">
            <div style="height:30px;width:150px;margin-top:20px;margin-left:20px;font-size:15px;color:Cyan;">
                <center>Enter Student Details</center>
            </div>
            <table>
                <tr>
                    <td>
                        Name
                    </td>
                    <td>
                        <apex:inputtext value="{!name}"/>
                    </td>
                </tr>
                <tr>
                    <td>
                        City
                    </td>
                    <td>
                        <apex:inputtext value="{!city}" />
                    </td>
                </tr>
                <tr>
                    <td>
                        Country
                    </td>
                    <td>
                        <apex:inputtext value="{!country}" />
                    </td>
                </tr>
                
                <tr>
                    <td>
                        Phone
                    </td>
                    <td>
                        <apex:inputtext value="{!phone}"/>
                    </td>
                </tr>
                <tr >
                    <td colspan="2" align="center">
                        <apex:commandButton value="INSERT" style="color:green;" action="{!ObjInsert}" />
                    </td>
                </tr>
            </table>
        </div>
    </apex:form>
</apex:page>
