[SOLVED] Parse error: syntax error, unexpected T_STRING
scrap0346 replied to scrap0346's topic in PHP Coding Help
[quote author=kenrbnsn link=topic=120240.msg493019#msg493019 date=1167367581] In this echo statement: [code]<?php echo 'You aren't logged in. Please <a href="register.php">register[/url] or <a href="login.php">log in.[/url]'; ?>[/code] you have a single quote inside a string that is delimited by a single quote which effectively ends the string so PHP doesn't know what to make of the rest of the string. I would write it like this: [code]<?php echo "You aren't" . ' logged in. Please <a href="register.php">register[/url] or <a href="login.php">log in.[/url]'; ?>[/code] Other people would probably code it differently. Ken [/quote] hey thanks man. i can't believe i spent all that time on a stupid single quotation mark. now i'm feeling kinda stupid. thanks again! -
I'm new to PHP and I'm trying to understand the basics of user authentication. I have a book on PHP and they give the example: [code]<?php $name = $_POST['name']; $password = $_POST['password']; if(!isset($_POST['name'])&&!isset($_POST['password'])) { //Visitor needs to enter a name and password ?> <h1>Please Log In</h1> This page is secret <form method="post" action="secretdb.php"> <table border="1"> <tr> <th> Username </th> <td> <input type="text" name="name"> </td> </tr> <th> Password </th> <td> <input type="password" name="password"> </td> </tr> <tr> <td colspan="2" align="center"> <input type="submit" value="Log In"> </td> </tr> </table> </form> <?php } else { // connect to mysql $mysql = mysqli_connect( 'localhost', 'mikemeye_webauth', 'webauth' ); if(!$mysql) { echo 'Cannot connect to database.'; exit; } // select the appropriate database $selected = mysqli_select_db( $mysql, 'auth' ); if(!$selected) { echo 'Cannot select database.'; exit; } // query the database to see if there is a record which matches $query = "select count(*) from authorized_users where name = '$name' and password = '$password'"; $result = mysqli_query( $mysql, $query ); if(!$result) { echo 'Cannot run query.'; exit; } $row = mysqli_fetch_row( $result ); $count = $row[0]; if ( $count > 0 ) { // visitor's name and password combination are correct echo '<h1>Here it is!</h1>'; echo 'I bet you are glad you can see this secret page.'; } else { // visitor's name and password combination are not correct echo '<h1>Go Away!</h1>'; echo 'You are not autorized to view this resource.'; } } ?>[/code] but when I run this, I get the error: Fatal error: Call to undefined function: mysqli_connect() in /home/mikemeye/public_html/test/secretdb.php on line 32 I did have to manually add the database ("auth"), the username ("mikemeye_webauth"), and password ("webauth") because the script the book gave me didn't work. Any help would be appreciated. Thanks!

I'm trying to setup a simple authentication for users but I keep getting this error: Parse error: syntax error, unexpected T_STRING, expecting ',' or ';' in /home/mikemeye/public_html/test/index.php on line 32 I'll admit I copied and pasted this code from a PHP forum, but I do understand HTML and the fuctions that are in the code, I'm just still working on the syntax of the functions. Any help would be appreciated. Thanks! here's the code: <?php session_start(); require_once('connect.php'); ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Index</title> <style type="text/css"> .container { text-align: center; border: 1px solid #000000; width: 300px; } td { text-align: left; } </style> </head> <body> <table class="container" align="center" cellspacing="0" cellpadding="0"> <tr> <td colspan="2" style="text-align:center;"><h1>Index</h1></td> </tr> <tr> <td colspan="2" style="text-align:center;"> <?php if(isset($_SESSION['username'])) { $data = mysql_fetch_array(mysql_query('SELECT * FROM `users` WHERE `username`="'.$_SESSION['username'].'"')); echo 'You are logged in, '.$_SESSION['username'].'. <br /><br />Your last log in was '.date('l, F j, Y', $data['last_seen']).' <br /><br />You registered '.date('l, F j, Y', $data['date_registered']).'<br /><br /><a href="logout.php">Click here to logout</a>'; }else{ echo 'You aren't logged in.<br /><br />Please <a href="register.php">register</a> or <a href="login.php">log in.</a>'; } ?> </td> </tr> </table> </body> </html> (connect.php just connects to the mysql database, it was just easier to put it in a separate .php file than have to rewrite it each time)
