HTML/PHP Checkbox not working

Question

I have a form:

<form method="post" action="">
    <p><input type="text" name="login" value="<?php if(isset($login_username)){ echo $login_username; } ?>" placeholder="<?php echo $lang['login_1']; ?>"></p>
    <p><input type="password" name="password" value="" placeholder="<?php echo $lang['login_2']; ?>"></p>

    <div class="options" style="margin: 5;line-height: 1.4;">
        <a onclick="showRegister();"><?php echo $lang['login_4']; ?></a><br>
        <a onclick="lostPassword();"><?php echo $lang['login_5']; ?></a>
    </div>

    <p class="remember_me">
        <label>
            <input type="checkbox" id="remember" <?php if(isset($login_remember)){ if($login_remember == "on"){ echo " checked"; }} ?>><?php echo $lang['login_3']; ?></input>
        </label>
    </p>
    <input type="hidden" id="action" name="action" value="login"></input>
    <p class="submit">
       <input type="submit" value="<?php echo $lang['login_button']; ?>">
    </p>
</form>

When i press the Submit button, $_POST returns: Array ( [login] => Username [password] => Password [action] => login )

But not the checkbox, anyone can help me?

EDIT: I added: name="remember" but still not working.

@Shannon I rolled-back your edit as you removed the OP's update. — jeroen

The problem with checkboxes is, the $_POST value of a checkbox is only set, if the box IS checked. If it is not, the value is not even posted. So you have to use isset() on the expected $_POST variable. If it is not set, the box is not checked. If it is set, you can evaluate the value.

Add name too

   <input type="checkbox" id="remember" name="login_remember" <?php if(isset($login_remember)){ if($login_remember == "on"){ echo " checked"; }} ?>><?php echo $lang['login_3']; ?></input>

Small addition: checkboxes do not appear in POST if they are not checked at the moment the form gets submitted.

correct. It seems the name should be login_remember. Please use isset, to see if it was checked
