PHP - Imagejpeg( ) Give Browser A File Name
Is it possible to feed the browser a default save as name for the image when outputting to the browser, instead of it defaulting to the .php file name? So, instead of myimage.php I could use imagename.jpg or whatever I want. Similar TutorialsAwhile ago I wrote a simple form to except image specific uploads from users and chmoded the directory to 777... worked great... Till there was a hack and then I found that chmod 777 is bad So changed the folder to 775, but now the upload script won't work. Can somebody point me to a post or article on how to give a file ownership or group permissions so it can safely run its uploads to the folder? I have tried google but keep getting Linux and Window OS results.. its a tough question to google. Any help is very much appreciated. I'm calling the image page via ajax. Depending on what date is selected will be written to the image. However I'm getting header error on my main page. What would be the proper way to display the generated image to the user? Can I do it without saving it?
// FETCH IMAGE & WRITE TEXT
$img = imagecreatefromjpeg('balloon.jpg');
$white = imagecolorallocate($img, 255, 255, 255);
$txt = "Hello World";
$font = "C:\Windows\Fonts\arial.ttf";
imagettftext($img, 24, 0, 5, 24, $white, $font, $txt);
// OUTPUT IMAGE
header('Content-type: image/jpeg');
imagejpeg($img);
imagedestroy($jpg_image);
// OR SAVE TO A FILE
// THE LAST PARAMETER IS THE QUALITY FROM 0 to 100
// imagejpeg($img, "test.jpg", 100);
Hey I've roughly written a php ftp browser (file displayer) and I cant seen to get around the problem how I would navigate through the folders, im fairly new to php and haven't had much experience just wondering that some methods could be for keeping track of what directory I am in and how to navigate up and down through the files and folders, I'm looking for ideas not necessarily solutions. I use a $_GET to tell the script what folder to look through but I want to be able to navigate solely through the hyperlinks Here is my code so far:
<?php
ini_set('upload_max_filesize', '10M');
ini_set('post_max_size', '10M');
ini_set('max_input_time', 300);
ini_set('max_execution_time', 300);
$host = "";
$user = "";
$password = "";
$ftp_connection = ftp_connect($host);
ftp_login($ftp_connection, $user, $password);
if (isset($_GET['page']))
{
$path = "/" . $_GET['page'];
}
else
{
$path = "/";
}
$file_list = ftp_nlist($ftp_connection, $path);
echo "<table border=1><tr><td>File Name</td><td>File Size</td><tr>";
for($index = 0; $index < sizeof($file_list); $index++)
{
echo "<tr>";
$file_size = ftp_size($ftp_connection, $file_list[$index]);
$file_name = $file_list[$index];
if ($file_size == -1)
{
echo "<td><a href=browse.php?page=" . $path . $file_name . ">" . $file_name . "</a></td><td><b>Folder</b></td></tr>";
}
else
{
echo "<td>" . $file_name . "</td><td>" . $file_size . "</td></tr>";
}
}
ftp_close($ftp_connection);

I am creating a simple website to handle a http get I need to do for a Android Application. I can write to a file but I am unable to open it in a browser. It just shows a blank page. When I download it from my browser (Firefox) to my hard drive (Windows 7) using my ftp I can view the .txt file. All i want to do is write to a text file. Any help would be nice. Sorry for sparse information. I am hosting it on 000webhost.com. Thanks My Code: 3 files blank "data.txt", index.html, process.php Index.html Code: [Select] <html><body> <h4>Tizag Art Supply Order Form</h4> <form action="process.php" method="post"> <select name="item"> <option>Paint</option> <option>Brushes</option> <option>Erasers</option> </select> Quantity: <input name="quantity" type="text" /> <input type="submit" /> </form> </body></html> process.php <html><body> <?php $quantity = $_POST['quantity']; $item = $_POST['item']; $myFile = "data.txt"; $fh = fopen($myFile, 'at') or die("can't open file"); $stringData = "Bobby Bopper"; fwrite($fh, $stringData); $stringData = "Tracy Tanner"; fwrite($fh, $stringData); fclose($fh); echo "You ordered ". $quantity .

Then it creates an Excel file and sends it to the browser to download. So you user will see the standard popup asking to save or open the file. Well, I am using ob_flush to try and output text to the browser while it is working so the user knows something is happening. But whenever I add the ob_flush lines in, it just sends a bunch of garbage text to the browser instead of downloading the file. Anyone know a way around this? Thanks Mike Hello Friends... I am creating a HTML webpage and connecting with MYSQL. If the client will check the conditions, it will pass it to PHP and get values from MYSQL and print it in the webpage as a HTML table format. Now i want to create a SAVE button and save the HTML TAble values as TXT tab demilited file. I tried of creating a TXT file by using fopen() and write the values by using fwrite() function. But it is working only in the putty. While running the program from the browser, its not working. Will somebody help me to solve this prob? I also was searched for creating a TXT file from HTML table. But i wouldnt get any codes reg this.... Thanks Rose Hi there, Can anybody help me to write php/javascript code which will allow users to open files directly from web browser into desktop application? Here is the specification: I have a photo editing business with many people working in Photoshop. I am currently developing a web based application (joblist) using Javascript and PHP which should allow the photoshop designers to browse and open files/images directly from joblist/web browser into photoshop. The reason I want this instead of browsing folder is that I have a database where I store who worked on which file, when and how long it took. The concept is that, designers will select a file and click on start, as soon as they click on start the original file will open in Photoshop and there will be an entry into database (using PHP). Once they finish the task they will close the file and click on Finish button. My joblist application will be published in a local server and the file will be open on a local network, so when they save the file it will be saved where the source file is located in (local server). The application should work in both PC and Mac. I have already done all other part of the application except file opening directly from browser to desktop application functionality. Anybody can help me to write the code (PHP or Javascript) which can open the file from browser (local server) directly into desktop application e.g. PHotoshop or Illustrator? Thank you very much I look forward to someone's real help!

I have php routines that print itineraries. For some reason the timestamp (1351378800) returns the same date Sunday 28th October (2012) as the time stamp (1351465200). $count = 0; while ($count <= ($nights+1)) { echo date ('l', $startdate1)." (".$startdate1.")"; echo "<br>"; echo date ('jS F', $startdate1); $startdate1 += 86400; // more code } Any ideas? Many thanks, Peter I am trying to learn PHP basics, and I just cant figure out a way to insert color when certain conditions are met. In my code below, I want to print out red color on lets say, odd numbers from 20-49. Appreciate your help big time!
<?php

echo "$i<br>";
}

Hey, I would like to get some practice in the following areas: - arrays (including multidimensional and associative) - functions and their return values I would appreciate it if anyone could give me/point me to some exercises/challenges. Thanks! Hi everyone, first thanks for caring to read my post! I am very very new to php but have a really good idea for a site so thought this could be a good chance to finally learn. The site is basically going to be a simple yet very well structured and organised repository for articles with the ability for users to post comments at the bottom of each article (logged in users). The users can also post articles and select which sections they want to put them in. The admin could then review all submissions and accept and then put them in the order in which they best fit (since the articles will usually be relevant to different stages and should be placed in order of assumed knowledge, if that makes sense) Kind of like a tutorials site with content being submitted. I imagine a really uncluttered site that looks more old school than web 2.0. From the first page is just like a simple search engine and underneath a kind of sitemap with each topic showing how many articles are in each. Then as you click into the topic area you are shown another sitemap like display of the articles in this which are perhaps some sectioning to define the type of article it is. As I say, I am quite new so I wondered if you had some suggestions of the top 'aids' to achieving this, and how you would suggest I progress to get it all setup? Or indeed any frameworks already that fit my needs? I hope to be active here and look forward to being to give something back some day. Edit: after reading this through,, I realise I just described a kind of wiki, but thats not really what I had in mind- more just how the old school basic but very clean and functional sites were back in the day (meaning no disrespect to any of the newer ones!). Thank you for reading. Hello, I have made a PHP script that will feed an existing XML file. The file stores song details like, title, name of singer etc ... Now the file structure is like this for the moment: Code: [Select] <?xml version="1.0" encoding="UTF-8"?> <music> <song> <title>Without me</title> <artist>Eminem</artist> <url>songs/coreIssues.mp3</url> <image>img/den.jpg</image> <discspeed>11</discspeed> </song></music> But I need it to be: Code: [Select] <?xml version="1.0" encoding="UTF-8"?> <music> <song mainTitle="Eminem - Without me"> <title>Without me</title> <artist>Eminem</artist> <url>songs/coreIssues.mp3</url> <image>img/den.jpg</image> <discspeed>11</discspeed> </song></music> I need it to be like that so if I want to delete a song from the list I just check for the element which will have a unique mainTitle and then delete that element with all it's details. Now, I've searched on Google for some solutions but didn't find any yet. Anyone here knows how to do this? Thanks! Alright, this is the code that i cant seem to get working. Its supposed to update the pin_lock field in my database. I have two databases that it needs to read from, the Account database to verify the login, then the Game database to modify the pin_lock field. It comes up that its sucessfully modified the entry but when i check it, its still the same as it was before. session_start(); if ($_POST["vercode"] != $_SESSION["vercode"] OR $_SESSION["vercode"]=='') { print("<center>Incorrect verification code!"); die(); } require_once('config.php'); mysql_select_db($accdb); $accountid=$_POST['accountid']; $pass=$_POST['pass']; $email=$_POST["email"]; $idnumber=$_POST["question"]; $phone=$_POST["answer"]; session_start(); if(!$_POST["accountid"]) { print("<center>Account ID Field Empty!"); die(); } if(!$_POST["email"]) { print("<center>E-mail Address Field Empty!"); die(); } if(!$_POST["question"]) { print("<center>Security Questions Field Empty!"); die(); } if(!$_POST["answer"]) { print("<center>Answer Field Empty!"); die(); } if(!ereg("^[0-9a-z]{4,12}$",$accountid)) { print("<center>Account ID Only letters from \"a\" to \"z\" and numbers, lenght of 4 to 12 characters"); die(); } if(!ereg("^[0-9a-z]{4,14}$",$pass)) { print("<center>Password Only letters from \"a\" to \"z\" and numbers, lenght of 4 to 14 characters"); die(); } if(!ereg("^[0-9a-zA-Z_]{4,128}$", (strtr($email, Array('@'=>'','.'=>''))))) { print("<center>E-mail Only letters a to z and special chars @ . are allowed!"); die(); } if($_POST["pass"]!=$_POST["pass2"]) { print("<center>Passwords do not match!"); die(); } $ac = mysql_fetch_array(mysql_query(sprintf("SELECT * FROM account WHERE name='$accountid'"))); if (!$ac) { print("<center>Account ID does not exist!"); die(); } $em = mysql_fetch_array(mysql_query(sprintf("SELECT * FROM account WHERE name='$accountid' AND email='$email'"))); if (!$em) { print("<center>E-mail is incorrect!"); die(); } $q = mysql_fetch_array(mysql_query(sprintf("SELECT * FROM account WHERE name='$accountid' AND idnumber='$idnumber'"))); if (!$q) { print("<center>Security Question is incorrect!"); die(); } $an = mysql_fetch_array(mysql_query(sprintf("SELECT * FROM account WHERE name='$accountid' AND phone='$phone'"))); if (!$an) { print("<center>Answer is incorrect!"); die(); } $ac = mysql_fetch_array(mysql_query(sprintf("SELECT * FROM account WHERE name='$accountid'"))); mysql_select_db($gamedb); $temp["query"] = sprintf("UPDATE cq_user SET lock_key='0' WHERE account_id='$selectedid'"); if (!mysql_query($temp["query"])) { die(mysql_error()); } else { print("<center>You bank pin has been removed!"); } Any ideas what is wrong with it? Hi all, I need some help. My ob_get_contents() is empty and gives me a empty file everytime. I tried different cache script it is still the same. I have also tried fwrite($fp, 'hello') In this case, it successfully writes to the file. But when i use ob_start and ob_get_contents, it will be empty. can anyone please advice. My simplified script is here <?php // Settings $cachedir = 'cache/'; // Directory to cache files in (keep outside web root) $cachetime = 600; // Seconds to cache files for $cacheext = 'html'; // Extension to give cached files (usually cache, htm, txt) // Ignore List $ignore_list = array( '/rss.php', '/search/' ); // Script $page = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; // Requested page $cachefile = $cachedir . md5($page) . '.' . $cacheext; // Cache file to either load or create $ignore_page = false; for ($i = 0; $i < count($ignore_list); $i++) { $ignore_page = (strpos($page, $ignore_list[$i]) !== false) ? true : $ignore_page; } $cachefile_created = ((@file_exists($cachefile)) and ($ignore_page === false)) ? @filemtime($cachefile) : 0; @clearstatcache(); // Show file from cache if still valid if (time() - $cachetime < $cachefile_created) { //ob_start('ob_gzhandler'); @readfile($cachefile); //ob_end_flush(); exit(); } // If we're still here, we need to generate a cache file ob_start(); ?> All My HTML AND PHP CODES TO RUN THE SITE <?php // Now the script has run, generate a new cache file $fp = @fopen($cachefile, 'w'); // save the contents of output buffer to the file @fwrite($fp, ob_get_contents()); @fclose($fp); ob_end_flush(); ?> Please take a look at the following code (this would work if the statement was SELECT instead of UPDATE) But I need to grab the following: Code: [Select] $result = mysql_query("UPDATE `AUCTIONS_MAIN` SET Current_Price = Current_Price + '$increase_price', Last_Bidder_Time = '$last_bidder_time' WHERE PId = '$id'"); //grab the new updated current price to save on different bidding history DB while($row=mysql_fetch_array($result)) { $current_price = $row['Current_Price']; } As you can see, I need to give the new Current_Price value to the $current_price variable. Obviously the while function is incorrect, I would really appreciate any ideas and/or suggestions on how I can grab this value. PS: I can't make a new query call with a select statement in order to know the new Current_Price. I need the direct updated value coming from the Update Statement, is this possible? Thanks a lot in advance!! |
