I have a scenario : A user needs to fill a form and after submitting, it should send the data of the form using POST API to some URL -

the user will need to be redirected to this page after the params passed to this URL, to this site.

I've tried to use the HttpRequest class and pass the params inside the body - But I didn't find a way to make a follow redirection to the page.

Using PageReference - don't sure how to send it using post - If I don't get wrong here - it always sent as a GET method - or not? When I tried to send it using PageReference - it using GET method and send the params through URL - I need them to be hidden from there.

Someone can help me with this?

The first method I tried using PageRefence : PageReference :

public PageReference doSave() {
    PageReference pageRef = new PageReference('https://www.someSite/payment/index.php/landing');

    return pageRef;

The Second method I tried using HttpRequest (after making the Page Refernce in comment): HttpRequest:

public void sendData(){

    String endpoint = 'https://www.someSite/payment/index.php/landing';
    String body = 'email=sal@salv.com&name=salv&token=a108e884&Id=23456';
    HttpRequest req = new HttpRequest();
    Http http = new Http();
    HTTPResponse response = http.send(req); 

Many thanks!

    Why don't you first make a request and then redirect? – Tushar Sharma Jan 23 '19 at 8:31
  • Its just the two methods I tried.. There is no connection between each other and each operates separately.. I mean that I tried the first one (Page Reference) alone and than the second (HTTP Request) alone - I will fix it - it is a little confusing – Salvation Jan 23 '19 at 8:59

Using PageReference is limited for such cases - So it must be done on the client side :

I used the "normal" form HTML element to submit the form with a post method, inside apex:form element.

I used apex:form to create my form with a commandButton for manipulation the data inside the controller and an onComplete tag for calling a javascript function to submit the "normal" HTML form from above.

In that way, I could achieve the desired redirection after sending data to another server with POST method. from the client side.

Full code is below: (it may be a better way for sharing the data between the inputs (normal input and apex:input)) and I will love to hear better ways.

          function submitForm() {
          document.querySelector("#zehut").value= document.querySelector("[id$='zehutId']").value;
          document.querySelector("#name").value= document.querySelector("[id$='nameId']").value;
          document.querySelector("#email").value= document.querySelector("[id$='emailId']").value;
          document.querySelector("#token").value= document.querySelector("[id$='tokenId']").value;
          document.querySelector("#sum").value= document.querySelector("[id$='sumId']").value;

    <apex:form styleClass="form-horizontal" >
      <apex:input value="{!zehut}" label="Id" id="zehutId" />
      <apex:input value="{!name}" label="Name" id="nameId" />
      <apex:input value="{!email}" label="Email"   id="emailId"/>
      <apex:input value="{!token}" label="Token"   id="tokenId"/>
      <apex:input value="{!sum}" label="Sum"   id="sumId"/>

      <apex:commandButton action="{!save}" rerender="hiddenForm" oncomplete="submitForm();" value="Submit" />
    <apex:outputText id="hiddenForm">
      <form id="secondForm" action="https://www.huika.com/payment/index.php/starting" method="post"
        target="_blank" enctype="application/x-www-form-urlencoded"  style="display:none;">
        <input id="zehut" name="zehut" value="{!zehut}"/>
        <input id="name" name="name" value="{!name}"   />
        <input id="email" name="email" value="{!email}"  />
        <input id="token" name="token" value="{!token}" />
        <input id="sum" name="sum" value="{!sum}" />

call apex method from Form element


If you are submitting form through visualforce page then during submission call webservice and then from frontend through oncomplete method navigate to next url.

  • I'm using site - The form is not filled in the vf page - actually, the VF page is an empty page with an action to the pageRefenrce - I'm using only the controller - Its filled in FormAssembly (a service to build custom web form and from there I redirect to my site.. - I must using it - it one if the client 's requirement ) - (Need to make some manipulation on the data and therefore I don't send it from there to the destination) – Salvation Jan 23 '19 at 9:04
