[SOLVED] Displaying a div with an if statement

[andrew_biggart]

Ok what i want to do is have this div

 

<div id="nav_menu">
<img alt="" src="../icons/myacc.gif" width="12" height="11" />
<a class="button6" href="my_profile.php">My Account</a>
<img alt="" src="../icons/mypro.gif" width="12" height="11" />
<a class="button6" href="profile.php?username=$myusername">My Profile</a>
<img alt="" src="../icons/mymes.gif" width="12" height="11" />
<a class="button6" href="my_profile_messages.php">My Messages</a>
<img alt="" src="../icons/myale.gif" width="11" height="11" />
<a class="button6" href="my_profile_alerts.php">My Alerts</a>
<img alt="" src="../icons/myreq.gif" width="12" height="11" />
<a class="button6" href="my_profile_requests.php">My Requests</a>
<img alt="" src="../icons/myfri.gif" width="12" height="11" />
<a class="button6" href="my_profile_friends.php">My Friends</a>
<img alt="" src="../icons/mylog.gif" width="12" height="12" />
<a class="button6" href="logout.php">Logout</a>

</div>
But i only want this information if the session $myusername is valid otherwise i dont want it to show up.

Can someone please point me in the right direction to do this as i am at the end of teather with it

Thanks

I didn't bother escaping all the quotes in the div, but you get the basic idea

 

session_start()
if(isset($_SESSION['myusername'])) {
echo "
<div id="nav_menu">
   <img alt="" src="../icons/myacc.gif" width="12" height="11" />
   <a class="button6" href="my_profile.php">My Account</a>
   <img alt="" src="../icons/mypro.gif" width="12" height="11" />
   <a class="button6" href="profile.php?username=$myusername">My Profile</a>
   <img alt="" src="../icons/mymes.gif" width="12" height="11" />
   <a class="button6" href="my_profile_messages.php">My Messages</a>
   <img alt="" src="../icons/myale.gif" width="11" height="11" />
   <a class="button6" href="my_profile_alerts.php">My Alerts</a>
   <img alt="" src="../icons/myreq.gif" width="12" height="11" />
   <a class="button6" href="my_profile_requests.php">My Requests</a>
   <img alt="" src="../icons/myfri.gif" width="12" height="11" />
   <a class="button6" href="my_profile_friends.php">My Friends</a>
   <img alt="" src="../icons/mylog.gif" width="12" height="12" />
   <a class="button6" href="logout.php">Logout</a>

</div>";
}

Thankyou, so do i need to chage all the " in the div to ' ??

[lonewolf217]

you escape " with \"

[andrew_biggart]

Ok so i have changed my mind! instead of displaying the div i want to display different info in the div depending on if the user is logged in or not!

 

if the user is not logged in i want to display the following login form.

<form method="post">
<table style="float: right">
<tr>
<td><input class="username" name="username" type="text" value="Username"/></td>
<td class="logmein">:Username</td>
<td><input class="password" name="Password1" type="password" value="Password"/></td>
<td class="logmein">:Password</td>
<td><input class="submit" name="Submit2" type="submit" value="C'umon in"/><a href="user_register.htm"><input class="register" name="Submit2" type="button" value="Register"/></a></td>
</tr>
</table>	
</form>

 

and if the user is logged in display a sub menu like this

<img alt="" src="../icons/myacc.gif" width="12" height="11" />
<a class="button6" href="my_profile.php">My Account</a>
<img alt="" src="../icons/mypro.gif" width="12" height="11" />
<a class="button6" href="profile.php?username=$myusername">My Profile</a>
<img alt="" src="../icons/mymes.gif" width="12" height="11" />
<a class="button6" href="my_profile_messages.php">My Messages</a>
<img alt="" src="../icons/myale.gif" width="11" height="11" />
<a class="button6" href="my_profile_alerts.php">My Alerts</a>
<img alt="" src="../icons/myreq.gif" width="12" height="11" />
<a class="button6" href="my_profile_requests.php">My Requests</a>
<img alt="" src="../icons/myfri.gif" width="12" height="11" />
<a class="button6" href="my_profile_friends.php">My Friends</a>
<img alt="" src="../icons/mylog.gif" width="12" height="12" />
<a class="button6" href="logout.php">Logout</a>

 

Basically i want the code to check whether or not the session myusername exists and echo the correct html if it is or isnt!

 

Thanks for your help

[lonewolf217]

its the exact same idea, just edit the IF statement for whatever condition you want.  I think with a little effort you can figure this one out on your own

[MatthewJ]

if all the quotes are doubles in the div... and you're not outputting vars... just change the quotes surrounding the content to single quotes... no need to escape 70 double quotes

[andrew_biggart]

ok so this is what i have got!

 

<?php
if(isset($_SESSION['myusername'])) {
echo "
   <img alt=/"/" src=/"../icons/myacc.gif/" width=/"12/" height=/"11/" />
   <a class=/"button6/" href=/"my_profile.php/">My Account</a>
   <img alt=/"/" src=/"../icons/mypro.gif/" width=/"12/" height=/"11/" />
   <a class=/"button6/" href=/"profile.php?username=$myusername/">My Profile</a>
   <img alt=/"/" src=/"../icons/mymes.gif/" width=/"12/" height=/"11/" />
   <a class=/"button6/" href=/"my_profile_messages.php/">My Messages</a>
   <img alt=/"/" src=/"../icons/myale.gif/" width=/"11/" height=/"11/" />
   <a class=/"button6/" href=/"my_profile_alerts.php/">My Alerts</a>
   <img alt=/"/" src=/"../icons/myreq.gif/" width=/"12/" height=/"11/" />
   <a class=/"button6/" href=/"my_profile_requests.php/">My Requests</a>
   <img alt=/"/" src=/"../icons/myfri.gif/" width=/"12/" height=/"11/" />
   <a class=/"button6/" href=/"my_profile_friends.php/">My Friends</a>
   <img alt=/"/" src=/"../icons/mylog.gif/" width=/"12/" height=/"12/" />
   <a class=/"button6/" href=/"logout.php/">Logout</a>

";
}
else{
<form method=/"post/">
<table style=/"float: right/">
<tr>
<td><input class=/"username/" name=/"username/" type=/"text/" value=/"Username/"/></td>
<td class=/"logmein/">:Username</td>
<td><input class=/"password/" name=/"Password1/" type=/"password/" value=/"Password/"/></td>
<td class=/"logmein/">:Password</td>
<td><input class=/"submit/" name=/"Submit2/" type=/"submit/" value=/"C'umon in/"/><a href=/"user_register.htm/"><input class=/"register/" name=/"Submit2/" type=/"button/" value=/"Register/"/></a></td>
</tr>
</table>	
</form>

}
?>

am i going along the right lines?

 

thankyou by the way

[corbin]

http://www.tizag.com/phpT/strings.php

 

 

That very lightly touches on it.

 

 

Think about PHP syntax...

 

 

$string = "something";

 

Now, what if something contains a "?  Wouldn't that make the string end?  So, you have to escape " unless you want the string to end:

 

$string = "Corbin said, \"Hello\"";

 

 

For example.

Ok im getting the blank screen which means theres an error in my code grr. I have tried the above solution by changing all " to /", and i have also tried changing them to '. But i cant get my head around this at all.

 

This is the code im trying to use can someone please have a scan through it and let me know what i am doing wrong! Thanks for your patience!

 

<?php
if(isset($_SESSION['myusername'])) {
echo "

you have to echo the HTML in your else statement

<?php
//session_start();

I totally suck at sessions, maybe if you do, too, you can try using cookies. This is what a snippet my panel looks like for editing my page so far, mainly in regards to the navigation:

 

<?php

/* NAVIGATION */
/* ADD ANYTHING YOU LIKE IN THE FORM OF: $navigation[] = array("link title", "link url", "link description"); */
	$navigation = array();
	$navigation[] = array("Home", $_SERVER['PHP_SELF'], "Main panel of ".$site_name." Management");
	$navigation[] = array("Log Out", $_SERVER['PHP_SELF']."?action=logout, "Log out of ".$site_name." Management");

/* GET USER LEVEL BASED ON THE INFORMATION SUPPLIED FROM THE COOKIE REGISTERED ON LOGIN */
	if($_COOKIE['levl'] == "3"){
		$user_type = "Administrator";
		$submit = "<input type=\"submit\" value=\"Submit Changes\" class=\"input\">";
		$navigation[] = array("Recent Activity", $_SERVER['PHP_SELF']."?action=recent_activity", "Modify the recent activity features");
	}
	elseif($_COOKIE['levl'] == "1"){
		$user_type = "Demonstration";
		$submit = "As a demo user you do not have the permissions to make changes.";
	}

	sort($navigation); /* Just to make things alphabetical, nawmeen? */
?>

Basically when you log in, your user level is set (1, 2, or 3) in a cookie ("levl"). As the highest level user (3) the "Recent Activity" link will be displayed for you, and only you. Any user with a level beneath that will not see it. Of course, this can easily be modified so that the only required parameter is that you are logged in. Something like:

<?php

if(isset($_COOKIE['username'])) /*or whatever you called your username cookie*/ {
	$navigation = array();
	$navigation[] = array("Home", $_SERVER['PHP_SELF'], "Main panel of ".$site_name." Management");
}

?>;

So for your case, maybe something like this would work

<?php
if(isset($_COOKIE['username'])){
$links = <<< html
  <img alt="" src="../icons/myacc.gif" width="12" height="11" />
   <a class="button6'" href="my_profile.php">My Account</a>
   <img alt="" src="../icons/mypro.gif" width="12" height="11" />
   <a class="button6" href="profile.php">My Profile</a>
   <img alt="" src="../icons/mymes.gif" width="12" height="11" />
   <a class="button6" href="my_profile_messages.php">My Messages</a>
   <img alt="" src="../icons/myale.gif" width="11" height="11" />
   <a class="button6" href="my_profile_alerts.php">My Alerts</a>
   <img alt="" src="../icons/myreq.gif" width="12" height="11" />
   <a class="button6" href="my_profile_requests.php">My Requests</a>
   <img alt="" src="../icons/myfri.gif" width="12" height="11" />
   <a class="button6" href="my_profile_friends.php">My Friends</a>
   <img alt="" src="../icons/mylog.gif" width="12" height="12" />
   <a class="button6" href="logout.php">Logout</a>
html;

   echo $links;
}

?>
