Parse Error with my login script (sort of)

Copy linkTweet thisAlerts:
Feb 12.2006

I have a script that is suppose to show the login box when someone isn’t logged in but shows the user’s username when succesfully logged in. But I get a Parse error: parse error, expecting `T_STRING’ or `T_VARIABLE’ or `T_NUM_STRING’ in /var/www/subdomain/menus/user/user.php on line 4 and the login box doesn’t even show up. Why and how can I fix this.

[code=php]<?php
session_start();
if (!$_SESSION[‘username’]) {
echo “You are logged in as ($_SESSION[‘username’])”;
} else {
include(“form.html”);
}
?>[/code]

@SpectreReturnsFeb 12.2006 — Use {} isntead of () for parsing inside of strings

[code=php]<?php
session_start();
if (!$_SESSION['username']) {
echo "You are logged in as {$_SESSION['username']}";
} else {
include("form.html");
}
?>[/code]

@BOB101authorFeb 12.2006 — Know when I add the {} i get a Parse error: parse error, expecting ','' or ';'' in /var/www/subdomain/menus/user/user.php on line 4. Why?

[code=php]<?php
session_start();
if (!$_SESSION['username']) {
echo 'You are logged in as {$_SESSION['username']} || <a href="user/logout.php">Logout</a>';
} else {
include("form.html");
}
?>[/code]

@bokehFeb 12.2006 — Variables are not accessible from inside a single quoted string literal. Also your if/else logic is wrong. It reads:[I] if $_SESSION['username'] has no value print it otherwise print the form[/I].

@BOB101authorFeb 12.2006 — Variables are not accessible from inside a single quoted string literal.[/QUOTE] What the freak does that mean? Dump it down, I'm just a noob at php. And are you saying get rid of the echo and use print or get rid of the include thing and just type out the form?

@bokehFeb 13.2006 — The string you wish to print is encapsulated within single quotation marks. When this is the case all characters are printed as exactly they appear in the string.

String literal: [I]A contiguous sequence of zero or more characters enclosed in quotation marks that is itself data, rather than a reference to data[/I]

Try to learn the vocabulary and then you will understand explanations better. It's a bit like going to hospital with a pain in the leg and when the doctor says the bone is broken telling him "[I]please dumb it down doctor... I'm a newb when it comes to hospitals... what is a bone?[/I]"

@SpectreReturnsFeb 13.2006 — Now that you've changed it to single quotes, a) it won't parse variables, and b) you can't use unescaped 's.

Should be:
[code=php]<?php
session_start();
if (!$_SESSION['username']) {
echo 'You are logged in as '. $_SESSION['username'] .' || <a href="user/logout.php">Logout</a>';
} else {
include("form.html");
}
?>[/code]

Also, I agree with bokeh. Learn atleast the basics before you come asking for help.

And, just for the record, Napoleon Dynamite was a horrible, horrible movie.

@bokehFeb 13.2006 — Also as I mentioned earlier I have trouble with this:[CODE]if ([color=red]![/color]$_SESSION['username']) {[/CODE]

@BOB101authorFeb 13.2006 — SpectreReturns I didn't ask for your dang opinion about the movie and I think it was pretty funny (for a movie with no plot). And thanks.

You're right. I just copied his code. Correct source should be:
[code=php]<?php
session_start();
if ($_SESSION['username']) {
echo 'You are logged in as '. $_SESSION['username'] .' || <a href="user/logout.php">Logout</a>';
} else {
include("form.html");
}
?> [/code]
