PHP - Writing Variable To .txt Using The Fwrite Function?
I am going through the tutorial found at http://goo.gl/69MeY and in my ultimate wisdom have decided to see if I can create a form, which you input some text, and then in the php file that handles the form in puts that variable into a text document using the fwrite function, basically creating a file from the website containing whatever text you put in. There is no specific purpose to this idea, I am just trying to implement everything I have learnt so far.
Form: http://pastebin.com/J62UHBeT PHP Handler: http://pastebin.com/FHuaKkxD I someone could point me in the right direction of what I am doing wrong it would be much appreciated Thanks in advance Michael Similar TutorialsDoes anyone know how I can make fwrite() write to a new line? I tried the following, but it didn't work. fwrite($fp, "".$_POST['feedback']."\n"); fwrite($fp, "".$_POST['feedback']."\r\n"); I'm working with little php background here and trying to write mysql table data to a text file. So far what I have is... $query = "SELECT * FROM `list` "; $result = mysql_query($query) or die("Query failed : " . mysql_error()); while ($line = mysql_fetch_array($result)) { $file = "export.txt"; $fhandle = fopen($file, 'w') or die("can't open file"); $stringdata = $line["listid"]. "\n"; fwrite($fhandle, $stringdata); //write to text file fclose($fhandle); } All this does is write the very last row in my table to the text file. If I switch fwrite to the 'a' mode, it works... but I don't want it to append to existing data. Ideally I'd like to wipe any contents in the existing text file clean before adding all new data from the query. Any thoughts? Thanks for the help! Hi there, I am trying to create a file using fwrite function, but for something reason all I get is a blank file with no content inside. Here is the code, go to the bottom where the fwrite function is called: <?php //Get Nohay Albums function function GetAlbums($cattype){ if ((isset($_GET['year']))||(isset($_GET['reciter']))){ //nothing displayed } else{ $query = "SELECT COUNT(Topic), SUM(Hits) AS totalhits, FileFormat, Speaker, Language, Year, FileType, Cat FROM nauhey WHERE Cat='".addslashes($cattype)."' AND Year='".date('Y')."' GROUP By Speaker, Year"; $result = mysql_query($query) or die (mysql_error()); //<!------------ Create Cache -------------!> //folder where cache is saved $path = "cache/"; //Page name format: FunctionName_Category_Year.html $pagename = $path."getalbums_".$cattype.".html"; $cacheFile = fopen($pagename, "w"); if ($cacheFile == FALSE){ die ("Unable to create cache file"); } //Get HTML in a variable $obstart = ob_start(); if ($obstart == FALSE){ die ("Unable to buffer cache content!"); } //<!------------ Cache closed -------------!> if ($cattype = strtolower('nauhey')){ while ($row = mysql_fetch_array($result)){ echo ("<div class='container'>"); echo ("<img src=\"http://localhost/HAQMOLAAALI/backed up/haqmolaali/images/".$row['FileFormat'].".gif\">"); echo ("<b style=\"font-size:10px; color:#000066; position:absolute; margin-left: 500px;\">DOWNLOADS: ".$row['totalhits']."</b>"); echo (" <a href=\"nohay.php?reciter=".urlencode($row['Speaker'])."&year=".urlencode($row['Year'])."\">".$row['Speaker']." Vol ".$row['Year']."</a> <b style=\"font-size:10px; color:#000000;\">(".strtoupper($row['Language']).")</b>"."\n"); echo ("<div class='small'><b>Year: ".$row['Year']." | Language: ".ucfirst($row['Language'])." | Tracks: ".$row['COUNT(Topic)']."</b></div>"); echo ("</div>"); }//while loop closed } else { while ($row = mysql_fetch_array($result)){ echo ("<div class='container'>"); echo ("<img src=\"http://localhost/HAQMOLAAALI/backed up/haqmolaali/images/".$row['FileFormat'].".gif\">"); echo ("<b style=\"font-size:10px; color:#000066; position:absolute; margin-left: 500px;\">DOWNLOADS: ".$row['totalhits']."</b>"); echo (" <a href=\"majlis.php?reciter=".urlencode($row['Speaker'])."&year=".urlencode($row['Year'])."\">".$row['Speaker']."

Help would be much appreciated. Thank you. Hi again.... I'm working on a project that creates a profile page for the user (i.e. 'username.php') when they register. Because there are two ways to register, through Facebook and through the website itself, there has to be an if statement in this page that it crates as to which ID to use for that user. Because Facebook usernames are not unique, we must identify a user through their OAuth User ID which is a 10 digit number. When a user registers through the website itself, usernames are unique so their profile page can be ID'd by their username. Here's the code that creates that profile page: function createProfile($user) { $userFile = 'users/'.$result['oauth_uid'].'.php'; $fh = fopen($userFile, 'w') or die("can't open file"); $stringData = "<?php\n" . '$pageowner = "' . $result['oauth_uid'] . '";' . "\n" . 'include "profile.php";' . "\n?>"; fwrite($fh, $stringData); fclose($fh); } $user is the username passed to the function when it's called. Currently that is set to create a line of code in the new profile page ('userid'.php) that looks like this: <?php $pageowner = "100001745088506"; include "profile.php"; ?> I want to add an IF to that page that follows this structu if oauth_provider == facebook { $pageowner = "oauth_uid" } else { $pageowner = username } But I don't know how to write that he $stringData = "<?php\n" . '$pageowner = "' . $result['oauth_uid'] . '";' . "\n" . 'include "profile.php";' . "\n?>"; to make it show up in the page it creates. I want that if statement to be written IN the page that is created. I just don't know the syntax well enough yet to do that. Would somebody help me out or point me in the right direction? Thanks! $DOCUMENT_ROOT=$_SERVER['DOCUMENT_ROOT']; $outputstring = $date."\t".$tireqty." tires \t".$oilqty."oil\t".$sparkqty." spark plugs\t\$".$totalamount."\t".$address."\n"; //open file for appending @$fp = fopen('$DOCUMENT_ROOT/../orders/orders.txt', 'ab'); if (!$fp) { echo '<p><strong>Your order can not be processed at this time. Please try again later</strong></p></body></html>'; exit; } //write to file fwrite($fp, $outputstring, strlen($outputstring)); flock($fp, LOCK_UN); fclose($fp); Can someone please explain to me why this Code is giving me the error? i've tried to take out $DOCUMENT_ROOT and specify where exactly i want the file to be /dir/dir/file.txt but it still gives me an error. hello there.. im planning to create a simple Online Users that is integrated to Facebook sdk. So far, i have the ff codes: index.php (this is where the online users listed) Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Online Users</title> <link type="text/css" rel="stylesheet" href="style.css" /> <script type="text/javascript" src="js/jquery.js"></script> <script type="text/javascript" src="js/ouser.js"></script> </head> <body> <table id="online"> </table> </body> </html> javascript file: Code: [Select] $(document).ready( function() { setInterval (loadLog, 2500); }); function loadLog(){ $.ajax({ url: "onlineusers.html", cache: false, success: function(html){ $("#online").html(html); }, }); } test.php (This is my temporary file to test the Login authentication for FB..

Thank you! Say I have an installation file, and they type in all their database information & click submit. How would I get that information to open up a file called config.php, and write to the $db_host, $db_pass, $db_user, and $db variables only? Is this possible? Thanks! Hi, I found this very good tutorial at IBM's site: http://www.ibm.com/developerworks/xml/library/x-validxphp/ BUT my question is, what if any arbitrary XML file is passed passed to this xml validator function as parameter (that I will soon write), so meaning there may not be an xml schema created, so how would I validate it then b/c the link above assumes there a schema is made to use to validate. Any help much appreicated! So I know next to nothing about PHP so I need some help with something thats probably incredibly easy. I just need a function(hope I'm using that right) that checks if a div with a certain class exists in the same page. then based on whether that's true or not changes the class of an image. This is how I imagine it looks except I don't know what to put in the if brackets to make it find the div and evaluate if its there or not. <img if (){ echo(class=\"visible\"); } else{ echo(class=\"hidden\"); } } src=\"icon.png\" /> Hello all, I have some piece of code that is nested like this $variable = 'This is a global argument'; function parentFunction($variable) { function childFunction() { echo 'Argument of the parent function is '.$GLOBALS['variable']; } childFunction(); } parentFunction(5); What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot . Thanks in advance I want to define a function instead of repeating query in all my php pages. I call a function by passing an $id value and from that function i have to get all the info related to that id, like name, description and uom.
I am trying to do this, but i dont know how to get these values seperately.
here is my function
function items($item_id)
{
$details = array();
$result = mysql_query("select item_id, name, uom, description from items where item_id=".$item_id."") or die (mysql_error());
while($row = mysql_fetch_array($result))
{
$details[] = array((stripslashes($row['name'])), (stripslashes($row['uom'])), (stripslashes($row['description'])));
}
return $details;
}
and i call my function like this
$info = items($id);Can somebody guide me in this I have a function that get's a quick single item from a query:
function gimme($sql) {
global $mysqli;
global $mytable;
global $sid;
$query = "SELECT ".$sql." FROM ".$mytable." WHERE sid = ".$sid; $result = $mysqli->query($query);
$value = $result->fetch_array(MYSQLI_NUM);
$$sql = is_array($value) ? $value[0] : "";
return $$sql; // this is what I've tried so far
$result->close();
}
It works great as:
echo(gimme("name"));
Then I realized that I could use that as a variable ('$name' in this case) elsewhere. However, I can't figure out how get that new, variable variable 'outside' of the function. As such, echo($name); isn't working outside the function. Is there a way to return a variable variable? In other words, is there a way to make a function that creates a variable variable that will available outside of the function?
Thanks
does anyone know how to decode this XML variable value into string values? I also need to know the oposite way: creating variable values into xml. I've tried several code examples but they did filter the requested data.

Hi, I'm having an image upload function I did create for few weeks ago - it has an variable called $newname, which contains the path and file. I'm then using the imageupload() function in another function called EditFrontPage(), which is used to 'update' some content. If I update the image, it runs the imageupload function, which is great, it resize and optimize the image, and it moves it to the folder I specified. What I then want, is within' my EditFrontPage() function, is to echo out the $newname variable from the imageUpload function. is there a way to do this? in a smart way? If my code is needed, you can take a look at it he http://codepad.org/poKNSU5H Thank you a lot guys! I have just started using functions, and have been following a few tutorials. I think im misunderstanding returns. lets say i have the variables called $math1 an $math2 and i want to make $total = $math1 + $math2; i then use return $total; I then thought i could echo $total and it would work outside of the function but its giving me an error of an underfines variable. Could anyone explain what im doing wrong please? thanks Code: [Select] class replayer extends users { --SNIP-- public $islive = false; --SNIP-- function chat($id, $nick, $chat) { --SNIP-- <----------- } } There's my code, I want to take the variable $islive from the above class and use it in the chat() function. How would I do it? I've tried making it a global inside of the chat() function. |
