PHP - Upload Box Query
Hi I was wondering if anyone could help me out with a code problem.
I am not very advanced with php but I do try to learn and I have been trying to figure out how to do something for a few hours now and im hoping someone here can help. Basically I have a php form with an upload box that posts data to my database this all works perfectly but my problem now is editing my data. When I edit the data and ignore the upload box it deletes the currect image in my database that I originally added. How can I edit the code so it keeps the currect image if the upload box is left blank. This is my currect modify page code: Code: [Select] <?php //This is the directory where images will be saved $target = "images/products/"; $target = $target . basename( $_FILES['link_image']['name']); //This gets all the other information from the form $link_image=($_FILES['link_image']['name']); //Writes the photo to the server if(move_uploaded_file($_FILES['link_image']['tmp_name'], $target)) { //Tells you if its all ok echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory"; } else { //Gives and error if its not echo "Sorry, there was a problem uploading your file."; } #+--------------------------------------- $short_desc = $_POST['short_desc']; $url = $_POST['url']; $category = $_POST['category']; $designers = $_POST['designers']; $shop = $_POST['shop']; $price = $_POST['price']; $rss_long_desc = $_POST['rss_long_desc']; $long_desc = $_POST['long_desc']; $news_id = $_POST['news_id']; $todays_date = date('Y-m-j H:i:s'); #+--------------------------------------- $modify_news_query = "UPDATE "; $modify_news_query .= $tbl_news; $modify_news_query .= " SET "; $modify_news_query .= " short_desc='" . $short_desc .

I have a table that has a list of products...There is a spot for an image for each of these products. What I want to do is give a user the option to add an image to an existing product. I have one spot for image_name, ie: this_picture.jpg and and BLOB field for the image file called: image this is my code.. Code: [Select] mysql_connect("locahost","root","") or die(mysql_error()); mysql_select_db("my_db") or die(mysql_error()); $picture = $_FILES['image']['tmp_name']; if(!isset($picture)) echo ""; else { $image = addslashes(file_get_contents($_FILES['image']['tmp_name'])); $image_name = addslashes($_FILES['image']['name']); $image_size = getimagesize($_FILES['image']['tmp_name']); if($image_size==FALSE) echo "This is not an Image"; else{ if(!$insert = mysql_query ("UPDATE `Sheet1` SET `image_name` = '".$image_name."', `image`='".$image."' WHERE pro_id ='".$id."';")) echo "Problem Uploading Image."; else{ $lastid = mysql_insert_id(); echo "Image Uploaded!<p />".$text."<p /><p /> Your Image:<p /><img src=get.php?id=$lastid>"; } } } The get.php page basically just displays the image and works fine but if you would need to see it for some reason I can provide it. I have a form that allows my client to update some products. Now the products are simple just basic info and 1 picture. I have set this up so they can edit the products and change the information, having done this many times in the past, but now hit a puzzling block that I am baffled. The client when editing is presented with the form with the information pulled from the database and the form fields loaded with that data ready to edit. The image can either be left alone or they can choose to upload a new image. They are shown the image they currently have stored in the database. The problem I have is EVEN if they decide not to upload an image and change other information, when the submit the form it must be sending a blank value for the image somewhere as it is updating the database and removing the image reference as if it has been removed. I have an if/else statement based on the form to perform 2 different queries for the update in mysql. Here is the code for the form update, as you can see the image should not update??

Im having a few problems, iv read up he http://www.php.net/manual/en/features.file-upload.multiple.php and it seems all i have to do is add [] to the form names to turn them into arrays. However when i come to upload the images, i keep getting the "$error[] = "Incorrect format!...." error from the code below. I cant seem to figure out what the problem is.

Here is my code: // Start MySQL Query for Records $query = "SELECT codes_update_no_join_1b" . "SET orig_code_1 = new_code_1, orig_code_2 = new_code_2" .

Why is this??? Code: [Select] You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '= new_code_1, orig_code_2 = new_code_2WHERE concat(orig_code_1, orig_c' at line 1 Hello all,
Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).
The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).
Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:
In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).
I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.
Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.
So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:
1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red.
2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red.
3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.
Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.
Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.
Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.
Cheers guys!

I wish to improve my coding base. Basically when you fill out the register form, it will check for data, then execute the insert query. But for some reason, the query will NOT insert into the database. In the following code below, I left out the field ID. Doesn't work with it anyways, and I'm not sure it makes a difference.

The code gets each row i'm looking for and sets up the query right, I hope I combined the entire query into one string each query seperated by a ; so it's like UPDATE `table` SET field2= '1' WHERE field1= '1';UPDATE `table` SET field2= '1' WHERE field1= '2';UPDATE `table` SET field2= '1' WHERE field1= '3';UPDATE `table` SET field2= '1' WHERE field1= '4';UPDATE `table` SET field2= '1' WHERE field1= '5'; this executes properly if i run the query in phpMyAdmin, however when I run the query in PHP, it does nothing... Any advice? Say I have this query: site.com?var=1 ..I have a form with 'var2' field which submits via get. Is there a way to produce: site.com?var=1&var2=formdata I was hoping there would be a quick way to affix, but can't find any info. Also, the query could sometimes be: site.com?var2=formdata&var=1 I would have to produce: site.com?var2=updatedformdata&var=1 Is my only option to further parse the query? I was just wondering if it's possible to run a query on data that has been returned from a previous query? For example, if I do Code: [Select] $sql = 'My query'; $rs = mysql_query($sql, $mysql_conn); Is it then possible to run a second query on this data such as Code: [Select] $sql = 'My query'; $secondrs = mysql_query($sql, $rs, $mysql_conn); Thanks for any help What would be the correct way to close a mysql query? At current the second query below returns results from the 1st query AND the 2nd query The 3rd query returns results from the 1st, 2nd and 3rd query. etc etc. At the moment I get somthing returned along the lines of...

What would cause this behavior - when I populate session vars from a MYSQL query, they stick, if I populate them from an MSSQL query, they drop. It doesn't matter if I get to the next page using a header redirect or a form submit. I have two session vars I'm loading from a MYSQL query and they remain, the two loaded from MSSQL disappear. I have confirmed that all four session vars are loading ok initially and I can echo them out to the page, but when the application moves to next page via redirect or form submit, the two vars loaded from MSSQL are empty. Any ideas? I am trying to create a query which reads and uses a previous query which could go on for upto four queries. For example: Query: $carcolour(red), Query: $carmodel(ford), Query: $enginesize(1600), Query: $carlocation(New York) This displays all red cars, which are Ford, which 1600CC, which are located in New York. or Query: $enginesize(1600), Query: $carcolour(red), Query: $carmodel(ford), Query: $carlocation(New York) This displays all 1600CC cars, which red car, which are Ford, which are located in New York. (Same result as above) I have found this guide but Im not sure it what I am looking for. I have also come across the Join function. However this seems to be based on joining two seperate queries. http://www.suite101.com/content/how-tor-run-multiple-mysql-queries-with-php-a105672 Can anyone advise on the best way to create a set of queries which reads and uses the results of the previous query? Good Day Guys

How do I get the script to try to restart the upload if it fails? (if if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) returns false) Code: [Select] <?php $file = 'file.wmv'; $remote_file = 'file.wmv'; // set up basic connection $conn_id = ftp_connect('ftp.eu.filesonic.com'); $ftp_user_name='username'; $ftp_user_pass='password'; // login with username and password $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass); // upload a file if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) { echo "successfully uploaded $file\n"; } else { echo "There was a problem while uploading $file\n"; } // close the connection ftp_close($conn_id); ?> Hi there We are hosting a web server that requires large files (100MB+) to be uploaded to it. We are using PHP upload scripts, and it is working, but we are getting complaints that the uploads are unreliable (some files fail to upload, with no error messages). I have been reading on various forums that FTP should rather be used for larger files, rather than HTTP. But from what I can see, there are some limitations, and I was wondering if there are any ways around these: - Using cURL would mean that the files would first be uploaded to a temp folder on the web server via HTTP, and then only sent via FTP. This defeats the purpose, because if it is already on the Web Server (which is hosted locally), then I might just as well move the file. - Using the built in FTP functionality of PHP, it appears that ones needs to know the full path of the source file. The users who are uploading files are accessing the Web server via a form in a browser, which will not give the PHP script the full path of the file to be uploaded. All we want is to have a reliable means for an end-user to access a site with a browser, fill in a form, choose a file to upload, and submit it. Additional functionality, like a progress bar, the ability to select multiple files and a resume option for failed uploads, would all be very nice. But the main concern is that the transfers be more reliable. Thanks for any advice. Mills Hey Im trying to upload a pdf file into a blob in a database. This script worked to insert images and I made a few minor changes so that it could do the same for pdf files. Only when i run the script in a browser it says error unknown file format. I dont understand this because I do list pdf as a valid file format. The txt and the doc possible file uploads are just there to take up spots where jpeg and gif were in the picture script i have no intention of actually uploading those. The file i tested was yes a pdf so that cant be the issue. Heres the script. Code: [Select] <?php $db_host = 'localhost'; // don't forget to change $db_user = 'root'; $db_pwd = 'dbpassword'; $database = 'mydbname'; $table = 'lit_gallery'; // use the same name as SQL table $password = '123'; // simple upload restriction, // to disallow uploading to everyone if (!mysql_connect($db_host, $db_user, $db_pwd)) die("Can't connect to database"); if (!mysql_select_db($database)) die("Can't select database"); // This function makes usage of // $_GET, $_POST, etc... variables // completly safe in SQL queries function sql_safe($s){ if (get_magic_quotes_gpc()) $s = stripslashes($s); return mysql_real_escape_string($s);} // If user pressed submit in one of the forms if ($_SERVER['REQUEST_METHOD'] == 'POST'){ // cleaning title field $title = trim(sql_safe($_POST['title'])); if ($title == '') // if title is not set $title = '(empty title)'; // use (empty title) string if ($_POST['password'] != $password)// cheking passwors $msg = 'Error: wrong upload password'; else { if (isset($_FILES['book'])) { @list(, , $ftype, ) = getimagesize($_FILES['book']['tmp_name']); // Get file type. // We use @ to omit errors if ($ftype == 3) // cheking image type $ext="pdf"; // to use it later in HTTP header elseif ($ftype == 2) $ext="txt"; elseif ($imtype == 1) $ext="doc"; else $msg = 'Error: unknown file format'; if (!isset($msg)) // If there was no error { $data = file_get_contents($_FILES['book']['tmp_name']); $data = mysql_real_escape_string($data); // Preparing data to be used in MySQL query mysql_query("INSERT INTO {$table} SET ext='$ext', title='$title', data='$data'"); $msg = 'Success: pdf uploaded'; } } elseif (isset($_GET['title'])) // isset(..title) needed $msg = 'Error: file not loaded'; // to make sure we've using // upload form, not form // for deletion if (isset($_POST['del'])) // If used selected some photo to delete { // in 'uploaded images form' $id = intval($_POST['del']); mysql_query("DELETE FROM {$table} WHERE id=$id"); $msg = 'Book deleted'; } } } elseif (isset($_GET['show'])){ $id = intval($_GET['show']); $result = mysql_query("SELECT ext, UNIX_TIMESTAMP(book_time), data FROM {$table} WHERE id=$id LIMIT 1"); if (mysql_num_rows($result) == 0) die('no image'); list($ext, $book_time, $data) = mysql_fetch_row($result); $send_304 = false; if (php_sapi_name() == 'apache') { // if our web server is apache // we get check HTTP // If-Modified-Since header // and do not send image // if there is a cached version $ar = apache_request_headers(); if (isset($ar['If-Modified-Since']) && // If-Modified-Since should exists ($ar['If-Modified-Since'] != '') && // not empty (strtotime($ar['If-Modified-Since']) >= $book_time)) // and grater than $send_304 = true; // image_time } if ($send_304) { // Sending 304 response to browser // "Browser, your cached version of image is OK // we're not sending anything new to you" header('Last-Modified: '.gmdate('D, d M Y H:i:s', $ts).'
