PHP - Download Missing Last Chunk
I'm using the following script to download large file (>100Mb). It works well except that it seems to not ever save the final chunk. If the file is 149,499 on the server, it finishes its download at 145,996. Why? How do I get the last 2% or so to flush and complete the download? Thank much for your help.
FYI, this also happens the same on smaller files so its not stopping for time or file size issues. Code: [Select] $path = "the/file/path.mp4"; $headsize = get_headers($path,1); $ext = str_from_last_occurrence($_vars['filepath'],"."); if ($ext=="mp3") { $type = "audio"; } elseif ($ext=="mp4") { $type = "video"; } function readfile_chunked($filename,$retbytes=true) { // Stream file $handle = fopen($filename, 'rb'); $chunksize = 1*(1024*1024); // how many bytes per chunk $buffer = ''; $cnt =0; if ($handle === false) { return false; } while (!feof($handle)) { $buffer = fread($handle, $chunksize); echo $buffer; ob_flush(); flush(); if ($retbytes) { $cnt += strlen($buffer); } } $status = fclose($handle); if ($retbytes && $status) { return $cnt; // return num. bytes delivered like readfile() does. } return $status; } header('Cache-Control: no-cache, no-store, max-age=0, must-revalidate'); header("Content-type: ".$type."/".$ext); header('Content-Length: ' . (string)($headsize['Content-Length'])); header('Content-Disposition: attachment; filename="'.str_from_last_occurrence($_vars['filepath'],"/").'"'); header("Content-Transfer-Encoding: binary"); readfile_chunked($path); exit; Similar TutorialsI have this chunk of code multiple times in if and elseif statements, to make the code more manageable I'd like to compile it together: Here's an excerpt: // ALL but NO OTHER if (($select_category == 'All') || (!isset($select_category)) && (!isset($most_liked))) { $query = "SELECT * FROM con, user WHERE con.user_id = user.user_id AND nickname = '$user_name' ORDER BY contributed_date DESC"; pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; knuffix_list ($query, $dbc); pagination_end ($pag_array); // CATEGORY but NOT most_liked } elseif (isset($select_category) && !isset($most_liked)) { $query = "SELECT * FROM con, user WHERE con.user_id = user.user_id AND nickname = '$user_name' AND category = '$select_category' ORDER BY contributed_date DESC"; pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; knuffix_list ($query, $dbc); pagination_end ($pag_array); The statements continue, as you can see it's the same chunk of code over and over, and I use the same chunk on a different page as well, just with a different query, that means the only thing that changes is the query. If I would want to change one thing about that chunk, I'd have to go through all of them and change it one by one, which is a pain. But if I put everything except the query into it's own function and then call that "ultimate" function it won't work and nothing will show up. When putting them into their own function, I also made sure that the three variables after pagination_start are at their right place, it's still didn't work. Any idea how I could compile this chunk of code in more manageable manner? Just to avoid any confusion, when I say "chunk of code" I mean this portion: pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; knuffix_list ($query, $dbc); pagination_end ($pag_array);
Basically I would like to place a link on my website and have the user download a file, but rather than just right clicking and choosing save target as, the link must be clicked, on the next page the file is fetched and then the client can download the file. How would I go about setting this up please? I have made a Php program that downloads an Inno setup installation file for installing a program. However, if I for one or another reason want to make a new download of the same Inno setup installation file, the previous file will still be found in the Download folder. Each of the downloads get a number in parenthesis, setup(1), setup(2), setup(3) etc. However, I wondered if it is posible to erase the previous file in the same process as I download a new one, so that however many downloads I do, there will all the time only be one occurence of this file in the Download folder. The download code is as follows: $exe = "Inno script/Test_setup.exe"; header("Content-Type: application/octet-stream"); header("Content-Disposition: attachment; filename=\"Test_setup.exe\""); header("Content-Length: " . filesize($exe)); readfile($exe); Thanks in advance. Sincerely
Really not seeing where my missing parenthesis goes. Code: [Select] if(isset($this->uri->segment(3)) AND ((empty($this->uri->segment(3))||($this->uri->segment(3) === FALSE)||(trim($this->uri->segment(3)) == ''))) To make a long story short, I have a series of forms, where certain options are visible depending on what the user selected on the previous form. The final form processing is where I'm having issues. I have the following for each option, to check if that option was selected (this is all somewhat pared down for clarity): Code: [Select] if (isset($_POST['option1']) && $_POST['option1'] > 0){ $option1 = mysql_real_escape_string($_POST['option1']); $query1 = "DELETE FROM table WHERE itemid = '$option1'"; } I have that basic thing for each of the options, where it assigns a deletion query based on each individual option. Later in my code, I have the following, which again checks if each option was selected (it's restated because it's after several error checks) then is supposed to run the query that was assigned in the previous part: Code: [Select] if ($_POST['option1'] > 0){ mysql_query($query1); } if ($_POST['option2'] > 0){ mysql_query($query2); } if ($_POST['option3'] > 0){ mysql_query($query3); } (etc, for all the options) My problem is that the queries are not executing and I can't see any reason why not. Query #1 is working... it executes the deletion query and all is well, but if I try to select any options other than #1, the query doesn't execute. I tried echoing the queries within the second if statements above (where it runs the queries) and it's echoing them fine (and they look normal), so I know it's able to run the queries, it just isn't... Am I blind? lol. I must be missing something obvious because this is driving me crazy. Thank you in advance. Please let me know if you need more info. Hi. I am new to PHP and trying out database connections. I am trying to query the database, to see if the date matches a record in the field 'date'. If it does echo yes, if there are no matches 'no'. Can anyone tell me what is missing from my code: Code: [Select] <?php $con = mysql_connect("localhost","root","root"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("date_picker", $con); $date= $_POST['date']; $new_date = date('Y-m-d',strtotime($date)); $sql = 'SELECT date FROM availability' if (date = $new_date) echo "Yes"; else echo "No"; mysql_close($con) ?> well when i am in my forum thing and i go to click on a 'topic' it says no topic exists. and there is one there idk what im missing in the code to make it view it in my table.. Code: [Select] <?php require("top.php"); ?> <div id='content'> <div id='homepageright'> <?php include_once("scripts/connect.php"); if($username){ $cid = $_GET['cid']; $tid = $_GET['tid']; $sql = "SELECT * FROM topics WHERE category_id='".$cid."' AND id='".$tid."' LIMIT 1"; $res = mysql_query($sql) or die(mysql_error()); if(mysql_num_rows($res) == 1){ echo "<table width='100%'>"; if($username){ echo "<tr><td colspan='2'><input type='submit' value='Add Reply' onClick=\"window.location = post_reply.php?cid=".$cid."&tid=".$tid."\" /><hr /> "; } While ($row = mysql_fetch_assoc($res)) { $sql2 = "SELECT * FROM posts WHERE category_id='".$cid."' AND topic_id= '".$tid."'"; $res2 = mysql_query($sql2) or die(mysql_error()); while ($row2 = mysql_fetch_assoc($res2)) { echo "<tr><td valign='top' style='border: 1px solid #000000;'><div style='min-height: 125px; '>".$row['topic_title']."<br /> by ".$row2['post_creator']." - ".$row2['post_date']. "<hr /> ".$row2['post_content']."</div></td><td width='200' valign='top' align='center' style='border: 1px solid #000000;'>User Info Here</td></tr><tr><td colspan='2'><hr /></td></tr>"; } echo "</table>"; } } else{ echo "This Topic Does Not Exist."; } } else{ echo "You Must Be Logged In To Continue."; } ?> </div> <div id='homepageleft'> <?php ?> </div> </html> </body> Let's say I have an array: $myArray[0] = "AtG2"; $myArray[1] = "AtG4"; $myArray[2] = "AtG1"; $myArray[3] = "AtG3"; $myArray[4] = "AtG5"; I want to sort it alphanumerically, so that the key/value pairs are as follows: [zero*] => "AtG1" [1] => "AtG2" [2] => "AtG3" [3] => "AtG4" [4] => "AtG5" * = I have to write [zero] because putting an actual zero number inside of [ and ] braces converts it to an HTML list bullet. It *appears* that natsort() is the proper function for this. The only problem I'm having is that natsort() doesn't manipulate key/value pairs. To confuse me even more, literally every example I can find on using natsort() uses it in conjunction with print_r() like so: natsort($someArray); print_r($someArray); Obviously, something is happening to $someArray when passed to natsort(), otherwise, print_r() wouldn't be able to order the indices in synch with the natural ordering algorithm. Well, I don't need my web app to use print_r()! I just need the darn key/value pairs reordered so that when I echo $myArray[3], I know I'm going to get "AtG4". What am I missing here? What is the point of calling it a "sort" if it doesn't manipulate the key/value pairs??? How can I get what I want?!? I am running a search query from MYSQL and it works, but now I want to get a little custom. I am selecting one field, out of many called paid1 which in database is either Yes or No. I want to do this: if paid1 is NO display Pay Now and everything else display Yes. I want this to be under new heading of paid1b. So the code should look something like this: $paid1b= if(['paid1'}==No){echo "Pay Now";} else {echo "YES";} But I am missing something somewhere. What is it? Thanks The user will click on the first button (.Applybutton) which opens a bootstrap modal with the ID ApplyModal. From then on an apply button (.SendButton) will send the job id that is passed in the first button press $_POST['jobid'] to the database. foreach ($export as $group => $arrayOpts) { //echo $arrayOpts[0]["choice"]; This returns No /** * If the option hasn't been selected, leave that part out entirely **/ if (!empty($arrayOpts)) // if the entire options array isn't empty, we'll display { if ($arrayOpts[0]["choice"]!="0" || $arrayOpts[0]["choice"]!="No") { $pdf->Cell(40,10,$group,0,1); $pdf->ImprovedTable($header,$arrayOpts); $pdf->Ln(); } } } Unfortunately I can't show print_r's at the moment, the main issue is it's running those $pdf-> lines even if that variable is equal to No, I proved it because up above commented out returns No, but it still runs the pdf code. Any thoughts? Been staring at it a while, maybe it's something in my conditional statement? Thanks. Hey guys, been awhile since I have been here, but I hit a little issue in reading session data reliably every time. What I am doing is reading the variables and values from a rarurlencoded string. Then putting that into a session array to populate parts of a form and fill in some hidden fields. After the form posts every now and then, about 1 in 50 or so attempts, I have one (always the same one) that just vanishes. Anyone ever experience anything like this? Hi all - It's gotta be something obvious, but I can't for the life of me how I'm sending output in this file before I send a header redirect.

I have a form with a table that contains ONLY dropdown menus for users to select quantities from 25 dinner items. It contains some Javascript, but nothing fancy. In an effort to establish my database and TEST to see how some PHP functions might respond so I could improve my form, I created a mini version of the db in MySQL. But when I click the submit button, the page blinks, the address bar fills with field names, but there is no connect. No error messages. No data transfer. NO NOTHING! I searched the web and copied a form and plugged it in (an html form, a php insert file, and a MySQL database) and it worked fine. I peared down my page to mirror it, and still, no success. What little detail am I missing?? If I have 25 fields but create a db for the first 6, should it function? If I reduce it and try to re-use the same db, am I persuing a problem? I've tried error trapping and changing the form inputs, but it just still doesn't connect. Please help! I am trying to get a paragraph from a website. Everything works but the first letter is kept on missing. The code shown below is used to get the paragraph. Not sure why the first letter is missing. Please help!!!
