music_fan01 Posted September 25, 2011 Share Posted September 25, 2011 I've found an example of guestbook that I would like to use on my site, but when I tested it I got the following error: Warning: fread() [function.fread]: Length parameter must be greater than 0 in C:\xampp\htdocs\xampp\index.php on line 66 I've included the bits of code for addguestbook.php guestbook.txt(didnt not include) and index.php. Also, is there a way that I could allow the client to look through out entries? I know very little about php, so any help is much appreciated. ------ addguestbook.php code ------ <HTML> <HEAD> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"><style type="text/css"> <!-- body,td,th { font-size: 12px; color: #000000; } a:link { text-decoration: none; color: #0066FF; } a:visited { text-decoration: none; color: #0066FF; } a:hover { text-decoration: underline; color: #0066FF; } a:active { text-decoration: none; } body { background-color: #CCCCCC; SCROLLBAR-FACE-COLOR: #0066FF; MARGIN: 0px; SCROLLBAR-HIGHLIGHT-COLOR: #0066FF; SCROLLBAR-SHADOW-COLOR: #0066FF; SCROLLBAR-3DLIGHT-COLOR: #0066FF; SCROLLBAR-ARROW-COLOR: #51B0F2; SCROLLBAR-TRACK-COLOR: #51B0F2; Courier New; SCROLLBAR-DARKSHADOW-COLOR: #000000 } --> </style> </HEAD> <BODY> <?php $file = "guestbook.txt"; $name = $_POST['name']; $email = $_POST['email']; $site = $_POST['site']; $msg = $_POST['msg']; $site = stripslashes($site); $msg = stripslashes($msg); $email = stripslashes($email); $name = stripslashes($name); $msg = str_replace ("<","<",$msg); $msg = str_replace ("\n","<br>",$msg); $site = str_replace ("<","<",$site); $site = str_replace ("\n","<br>",$site); $email = str_replace ("<","<",$email); $email = str_replace ("\n","<br>",$email); $name = str_replace ("<","<",$name); $name = str_replace ("\n","<br>",$name); if(empty($email) || empty($name) || empty($msg)) { echo "<h3>Sorry all fields are required</h3>"; } else { $fp = fopen($file,"a"); fwrite($fp, ' <font size="3"> <BR><BR> Name: '.$name.'<BR> Email: <a href="mailto:'.$email.'">'.$email.'</a><BR> Home Page: <a href="'.$site.'">'.$site.'</a><BR>Message: '.$msg.'<BR> '); fclose($fp); echo '<font size="3"><p align="center">Thank you '.$name.' for singing my guestbook</p></font>'; } ?> <div align="center"></div> <div align="center"></div> <div align="center"></div> <div align="center"></div> <p align="center"><a href="YOU`R INDEX.PHP LINK HERE">Back to GuestBook</a></p> <div align="center"></div> </BODY> </HTML> ---- finish ----- ---- index.php code ----- <HTML> <HEAD> <style type="text/css"> <!-- .style1 {font-size: 12px} body,td,th { font-size: 14px; } a { font-size: 12px; } body { background-color: #CCCCCC; SCROLLBAR-FACE-COLOR: #0066FF; MARGIN: 0px; SCROLLBAR-HIGHLIGHT-COLOR: #0066FF; SCROLLBAR-SHADOW-COLOR: #0066FF; SCROLLBAR-3DLIGHT-COLOR: #0066FF; SCROLLBAR-ARROW-COLOR: #51B0F2; SCROLLBAR-TRACK-COLOR: #51B0F2; Courier New; SCROLLBAR-DARKSHADOW-COLOR: #000000 } a:link { color: #0066FF; text-decoration: none; } a:visited { text-decoration: none; color: #0066FF; } a:hover { text-decoration: underline; color: #0066FF; } a:active { text-decoration: none; } --> </style> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"><BODY> <form method="post" action="addguestbook.php"> <div align="center"></div> <div align="center"></div> <div align="center" class="style1"></div> <div align="center"><span class="style1">Name:</span><br /> <input name="name" type="text" size="30" maxlength="40" /> <br /> <span class="style1"><br /> Email:</span><br /> <input name="email" type="text" size="30" maxlength="40" /> <br /> <br /> <span class="style1">Home Page:</span><br /> <input name="site" type="text" size="30" value="http://" maxlength="40" /> <br /> <br /> <span class="style1">Message:</span><br /> <textarea name="msg" cols="22" rows="6"></textarea> <br /> <br /> <input type="reset" value="Reset" /> <input type="submit" value="Send" /> </div> <div align="center"> <p> </p> <?php $file = "guestbook.txt"; if (fopen($file, "r")) { $fil = "guestbook.txt"; $fo = fopen ($fil, "r"); $con = fread ($fo,filesize ($fil)); fclose ($fo); echo "$con"; } else { echo "<h3>Sorry there was an error please contact us now<h3>"; } ?></div> </BODY> </HTML> ---- finish ----- Quote Link to comment Share on other sites More sharing options...
Pikachu2000 Posted September 25, 2011 Share Posted September 25, 2011 Since the error seems to indicate filesize($fil) is returning a value of zero, have you tried var_dump(filesize($fil)) to see what the value actually is? Quote Link to comment Share on other sites More sharing options...
music_fan01 Posted September 25, 2011 Author Share Posted September 25, 2011 Never mind, oddly enough and not too sure how, but it works now just right since I copied the code again, then tested it on my localhost. I have another question though, how can add a timestamp and a date to my entries? Quote Link to comment Share on other sites More sharing options...
