if isset (Multiple cookies)

NievesCorp · **if isset (Multiple cookies) -** 07-20-2012, 01:22 AM

Hello;

My goal tonight is to create a cookie-operated member's menu. I want to make it so that if you're not logged in with your primary and secondary credentials you see a Log in dropdown menu, but if you're logged in, you see a dropdown with your name on it (stored in a cookie). I also want to make it so that if you're logged in, but don't have your name saved, the dropdown menu just says "You" as a header. Below I present the code written so far, I need to know how to correct ot, sinse I see that it's not totally correct.

Code:

    <? if (!isset($_COOKIE["name"]) || ($_COOKIE["primary_username"]) || ($_COOKIE["primary_password"]) || ($_COOKIE["secondary_username"]) || ($_COOKIE["secondary_password"])) { ?>
    <li class="menu_right"><a href="#" class="drop"><? if (isset($_COOKIE["name"])) { $name = $_GET['name']; echo $name; } else { echo "You"; } ?></a>
     <div class="dropdown_1column align_right">
      <div class="col_1">
       <ul class="simple">
        <li><a href="#">FreelanceSwitch</a></li>
        <li><a href="#">Creattica</a></li>
        <li><a href="#">WorkAwesome</a></li>
        <li><a href="#">Mac Apps</a></li>
        <li><a href="#">Web Apps</a></li>
        <li><a href="#">NetTuts</a></li>
        <li><a href="#">VectorTuts</a></li>
        <li><a href="#">PsdTuts</a></li>
        <li><a href="#">PhotoTuts</a></li>
        <li><a href="#">ActiveTuts</a></li>
        <li><a href="#">Design</a></li>
        <li><a href="#">Logo</a></li>
        <li><a href="#">Flash</a></li>
        <li><a href="#">Illustration</a></li>
        <li><a href="#">More...</a></li>
       </ul>   
      </div>
     </div>
    </li>
    <? } else { ?>
    <li class="menu_right"><a href="http://x.<? echo $base; ?>/search/search.php" class="drop">Log in</a>
     <div class="dropdown_2columns align_right">
      <div class="col1_2">
      <div class="col_1">
       <p><b>Name:</b></p>
      </div>
      <div class="col_1">
       <input class="v2" name="name" placeholder="John Davis" style="width:98%" type="text" value=""/>
      </div>
     </div>
    </li>
    <? } ?>

Oh, and here's the url just in case: http://www.spiritfonds.comlu.com/foyer.html

Thanks in advance!

When I tested your code, I got "You" printed althogh I am not logged in. So, how about
the following code, adding another if syntax for $name?

<? if(isset($_COOKIE["name"])) {
$name = $_GET['name'];
if($name) {echo $name;}
else {echo "You";}
} ?></a>

Will try & reply.

Thanks!

Hmmm, it seems to work, but now we don't get the "Log in" menu OR the "You" menu.
I also have another question, is the Boolean of cookies legit?

The Code (Revised):

Code:

<? if (!isset($_COOKIE["name"]) || ($_COOKIE["primary_username"]) || ($_COOKIE["primary_password"]) || ($_COOKIE["secondary_username"]) || ($_COOKIE["secondary_password"])) { ?>
    <li class="menu_right"><a href="#" class="drop"><? if(isset($_COOKIE["name"])) { $name = $_GET['name']; if($name) {echo $name;} else {echo "You";} } ?></a>
     <div class="dropdown_1column align_right">
      <div class="col_1">
       <ul class="simple">
        <li><a href="#">FreelanceSwitch</a></li>
        <li><a href="#">Creattica</a></li>
        <li><a href="#">WorkAwesome</a></li>
        <li><a href="#">Mac Apps</a></li>

Well, firstly, notice that using php shorttags is a bad habbit.
Then you should take a note that the menu only shows if your "name" isn't set, so whenever $_COOKIE["name"] is set, you will get to the "ELSE" part of the main code.

Also notice that you should use the isset() code for all of your cookie "ifs" (else some servers might give a "Notice: Undefined index: COOKIEKEY in " every now and then)

I acctually believe that you want the menu to only show when they have the cookie set? In that case, this code should work (I changed the shorttags to normal tags when I did this small, well "fix")

PHP Code:


			
    <?php 
    $_COOKIE["name"] = "YoDude";
    if (    
        isset($_COOKIE["name"]) || 
        isset($_COOKIE["primary_username"]) || 
        isset($_COOKIE["primary_password"]) || 
        isset($_COOKIE["secondary_username"]) || 
        isset($_COOKIE["secondary_password"])) { 
    ?>
    <li class="menu_right"><a href="#" class="drop">
    <?php 
        if (isset($_COOKIE["name"])) { 
            echo $_COOKIE['name']; 
        } else { 
            echo "You"; 
        } 
    ?>
        </a>
     <div class="dropdown_1column align_right">
      <div class="col_1">
       <ul class="simple">
        <li><a href="#">FreelanceSwitch</a></li>
        <li><a href="#">Creattica</a></li>
        <li><a href="#">WorkAwesome</a></li>
        <li><a href="#">Mac Apps</a></li>
        <li><a href="#">Web Apps</a></li>
        <li><a href="#">NetTuts</a></li>
        <li><a href="#">VectorTuts</a></li>
        <li><a href="#">PsdTuts</a></li>
        <li><a href="#">PhotoTuts</a></li>
        <li><a href="#">ActiveTuts</a></li>
        <li><a href="#">Design</a></li>
        <li><a href="#">Logo</a></li>
        <li><a href="#">Flash</a></li>
        <li><a href="#">Illustration</a></li>
        <li><a href="#">More...</a></li>
       </ul>   
      </div>
     </div>
    </li>
    <?php } else { ?>
    <li class="menu_right"><a href="http://x.<?php echo $base; ?>/search/search.php" class="drop">Log in</a>
     <div class="dropdown_2columns align_right">
      <div class="col1_2">
      <div class="col_1">
       <p><b>Name:</b></p>
      </div>
      <div class="col_1">
       <input class="v2" name="name" placeholder="John Davis" style="width:98%" type="text" value=""/>
      </div>
     </div>
    </li>
    <?php } ?>

But The way you made the code, eighter you'll never need to use the "ELSE -> 'YOU'" or "IF ->'name'", deepending if you use isset() or !isset() on the $_COOKIE["name"]

NievesCorp · 07-20-2012, 07:13 AM

Well, Leader I must say, I ow you one. It worked very well after I removed the -$_COOKIE["name"] = "John";- bit, because that bit was preventing the user from being able to enter their credentials.

Now my next task would be to create the actual "Mass Log in" processor and link it, work for tomorrow alongside the custom radio player.

Now let's talk about that "bad habit" of <? ?> tags, why is it a bad habbit, in your opinion?

grace1004 · 10:42 AM

On 000webhost.com server php.ini setting for short_open_tag is on. So, <? ?> is working
in this hosting. However, if you use short_open_tags with xml declaration something like
<? xml version="1.0" encoding="UTF-8" ?>, it causes error as php tags and xml declaration
tags are same.

Leder678 · 07-21-2012, 08:29 AM

well, shorttags doesn't work on every server, but the normal tags do.
That's the main reason I'd advice everyone to use the normal tags, pluss, drupal standards work that way, and they have some pretty smart standards

Go to your Cpanel - >> Software/Services - click 'View PHP Configuration', you will get
a table showing configuration of php, Apache and MySQL for your hosting server. In the
table under PHP Core, you will see short_open_tag is On, in which case <? ?> is working.
If you test a php file with short_open_tag, you will see it is working.

I'm talking about servers in general, not only 000webhost servers.
And whenever you move to a different host, there is a slight chance that the shorttags won't work.
And if you are ever planning to make a CMS or any public scripts, you'll end up having a lot of people whom cannot use your script IF you use shorttags, allthough a lot of people could fix it, a lot of people have no idea how to open a Php file.

Just sayin' it's kinda a bad habit to use shorttags.
