Question

I'm trying to change my form action in my HTML then submit using javascript.

The conditions are in PHP .

I need help if anyone can assist me.

This is my PHP function :-

<?php
error_reporting(0);

if(isset($_POST['email'])){
    $email=$_POST['email'];
   if(!empty($email)) {
       $chrono = 0;
    } else {
       $chrono = 1;
    }
}
?>

The motive of the PHP is to check null email entry.

Here's the javascript function :-

<script type="text/javascript"> 
    function fireform(val){ 
    // missing codes
      document.forms["demoform"].action=val; 
      document.forms["demoform"].submit(); 
    } 
    // missing codes    
</script>

HTML :-

<form name="demoform" action="">        
<input type ="text" name="name" id="name">             
<input type="hidden" name="buttonpressed" id="buttonpressed"> 
<input type="button" value="submit B" onclick="fireform('b')">

I want to do it in a way , when the user entered an empty email , the PHP will read it as chrono = 0. Then goes to javascript , if the chrono equal to 0 , the action will remain empty.

If the chrono = 1 , the javascript will change the action of the form and submit.

I need help thanks.

I would recommend checking the email field (for being empty) in javascript, and when you have set the proper action submit the form in javascript.

Check the field:

$('#<enter id of field>').val();

Update the action:

$('form').attr('action', 'Enter your updatet action here');

Submit the form:
