如何使用Google+登录信息

Question

I managed to get the user information using Google+ login.

    if (isset($authUrl)) {       
    echo "<a href='" . $authUrl . "'><img src='img/google.png'></a>";
} else {
    print "ID: {$id} <br>";
    print "Name: {$name} <br>";
    print "Email: {$email } <br>";
    print "Image : {$profile_image_url} <br>";
    print "Cover  :{$cover_image_url} <br>";
    print "Url: {$profile_url} <br><br>";
    echo "<a class='logout' href='?logout'><button>Logout</button></a>";
}

This is in a login.php file where the user logs in. How can I pass this data to the header.php so I can remove the Login and Register buttons and add the user name and image?

Answer 1

To pass info via GET:

For redirecting in php, you use header('Location:file_name')

header('Location: header.php?var1=val1&var2=val2');

Session:

// index.php
session_start(); //start session
$_SESSION['varName'] = 'varVal'; //make a session variable
header('Location: header.php'); // redirect to header.php

// header.php
session_start(); //start session
$myVar = $_SESSION['varName']; //access your session here

Post: Take a look at this.

Another way is to include a hidden field in a form that submits to page two:

<form method="post" action="header.php">
    <input type="hidden" name="varname" value="var_value">
    <input type="submit">
</form>

And then on header.php:

//Using GET
$var_value = $_GET['varname'];

//Using POST
$var_value = $_POST['varname'];

//Using GET, POST or COOKIE.
$var_value = $_REQUEST['varname'];

Just change the method for the form to get if you want to do it via get.

Happy Coding! :)
