How to configure a URL path using PHP

Question

I am learning the Ajax process. My problem: when I submit the form, it works and redirects to another page. But when I click the back button, I am not redirected to the previous page. What am I doing wrong here?

<form id="form-admin-login"> <input name="username" type="text" placeholder="User name" class="input-field" required=""> <input name="password" type="password" placeholder="Password" class="input-field" required=""> </form> <button name="submit" onClick="submit_login()" class="btn btn-login">Login</button> 

Ajax

 function submit_login(){ $.ajax({ type: "POST", data: $("#form-admin-login").serialize(), url: "ajax/ajax-admin-login.php", dataType: "json", cache: false, beforeSend:function(){ }, success: function(data) { if(data['error']==0) { window.location.replace('dashboard.php'); } else if (data['error']==1) { $("#showError").removeClass("hide"); $("#error-message").html(data['message']); } }, error: function(jqXHR, textStatus, errorThrown){ } }) 

Answer 1

You need to redirect using

 window.location.assign(url); window.location = url; window.location.href = url; 

not with

 window.location.replace(URL); 

because location.href will just navigate to the new url. On the other hand, the replacement method moves to the URL without adding a new entry to the history.
