I have a form which have 9 Steps I have design in this steps using Sessions and Code Whole Form in Php Using Concatenate Method. But Now I am facing a problem i want to allow the user to go on previous step when he click the step back button.
When i am trying to code in on click event php return me unexpected if or unset error. I tried two methods which is written below
// METHOD 1
$form .= "<button type='button' class='btn btn-warning' onclick='".unset($_SESSION['m_id']); ."' id='back'>Back</button>";
// METHOD 2
$form .= "<button type='button' class='btn btn-warning' onclick='".
if(isset($_SESSION['m_type'])){
unset($_SESSION['m_type']);
}
."' id='back'>Back</button>";
I am creating this form in php that is why in the last i echo my form variable.
