PHP - Limit File Type Help
I have this code which uploads fine but I am trying to limit the type of files users can upload. For some reason this code still let any file type to be uploaded being very new to php any help would be Appreciated. Quote Code: [Select] <?php if ((($_FILES["image"]["type"] == "image/gif") || ($_FILES["image"]["type"] == "image/jpeg") || ($_FILES["image"]["type"] == "image/pjpeg")) && ($_FILES["image"]["size"] < 20000)) { if ($_FILES["image"]["error"] > 0) { echo "Error: " . $_FILES["file"]["error"] . "<br />"; } else { echo "Upload: " . $_FILES["image"]["name"] . "<br />"; echo "Type: " . $_FILES["image"]["type"] . "<br />"; echo "Size: " . ($_FILES["image"]["size"] / 1024) . " Kb<br />"; echo "Stored in: " . $_FILES["image"]["tmp_name"]; } } $target = "testimages/"; $target = $target . basename( $_FILES['image']['name']); // $company=$_POST['company']; $image=($_FILES['image']['name']); mysql_connect("localhost", "user", "pass") or die(mysql_error()) ; mysql_select_db("testupload") or die(mysql_error()) ; mysql_query("INSERT INTO `table` (company, image) VALUES ('$company', '$image')") ; if(move_uploaded_file($_FILES['image']['tmp_name'], $target)) { echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded, and your information has been added to the directory"; } else { echo "Sorry, there was a problem uploading your file."; } ?> Similar TutorialsHiya, Firstly, I'm a complete novice, apologies! But I have got my upload.php working which is nice. I will post the code below. However, I would now like to restrict the file size and file type to only word documents. I currently have a restriction of 200KB but it's not working - no idea why as I've looked at other similar codes and they look the same. Also, just to complicate things - can I stop files overwriting each other when uploaded? At the moment, if 2 people upload files with the same name one will overwrite the other. Is this too many questions in 1? Any help is very much appreciated! Code below: Code: [Select] <form enctype="multipart/form-data" action="careers.php" method="POST"> Please choose a file: <input name="uploaded" type="file" /><br /> <input type="submit" value="Upload" /> </form> <?php $target = "upload/"; $target = $target . basename( $_FILES['uploaded']['name']) ; $ok=1; //This is our size condition if ($uploaded_size > 200) { echo "Your file is too large.<br>"; $ok=0; } //This is our limit file type condition if ($uploaded_type =="text/php") { echo "No PHP files<br>"; $ok=0; } //Here we check that $ok was not set to 0 by an error if ($ok==0) { Echo "Sorry your file was not uploaded"; } //If everything is ok we try to upload it else { if(move_uploaded_file($_FILES['uploaded']['tmp_name'], $target)) { echo "Your file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded."; } else { echo "Sorry, there was a problem uploading your file."; } } ?> Folks,

Can you spot my coding error ? Hi Chaps, I'm using readfile to force the download of a file: set_time_limit(0); $file = 'monkey.gif'; if (file_exists($file)) { header('Content-Description: File Transfer'); header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename='.basename($file)); header('Content-Transfer-Encoding: binary'); header('Expires: 0'); header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); header('Pragma: public'); header('Content-Length: ' . filesize($file)); ob_clean(); flush(); readfile($file); exit; } flush(); And this works fine, however, I do have some software installation files that could be downloaded (these are in excess of 280Mb). I have checked php.ini: Quote memory_limit = 128M post_max_size = 300M But Internet Explorer hangs and then crashes. Is there a way to allow big files to download using this method, or is there another way of forcing the download, without php 'reading' the file first? I'm guessing that the problem lies with the memory_limit being smaller than the file size. Is it a good idea to increase the memory_limit to eg. 280Mb? Cheers I have a simple script which records search terms and writes them to an external file. I would like to limit this file size. The Use: I have a search page where people can search for PDF files. I would like to have a 'cloud tag' or list of the most recent terms searched at the bottom of the page. Here is my script which works beautifully: <?php $pattern = "/filetype:(\w+)/"; // filteype:(wildcard for word) to grab the file extension along with the word filetype: if ( $_GET['q'] == "" ) { $term = ""; } else { $term = preg_replace("$pattern", '', $_GET['q']); // get rid of the filetype parameter } $searched = $term . ", "; $fopen = fopen("searched.html", "a"); fwrite($fopen, $searched); fclose($fopen); ?> The above code grabs the search term when the SERP page is opened, and writes it to a file. I will later use phpInclude to put the contents of that file on the bottom of my search engine page. The problem is that after a million searches, this file will be huge! Question: How can I limit the file size and organize these search terms so that the most recent ones appear on the page? Hi guys, with code below i can upload pictures to database, however i need to limit the file upload. I have this code done with help of php freak forum and i am a newbie so can u help me please? thanks in advance if (isset($_POST['register']) && $_POST['register']){ //image1 $nameone=$_FILES['myfileone']['name']; if ($nameone) { $dst_filename = resize_upload_image($_FILES['myfileone'], "images/"); if ($dst_filename !== false) { extract($dst_filename); $image1 = mysql_query ("INSERT INTO img SET image='$img_filename', thumb='$thumb_filename', refimage='$reference'"); } } } ?> <form action='' method='POST' enctype='multipart/form-data'> <p>File: <input type='file' name='myfileone'> I'm trying to add a file size limit to my upload form-code (below) Unless buffer overflows or breaking out of code to perform a new command are problems that have been solved.... I am trying to figure out the proper PHP method for setting a boundary on a variable within a script. I have this variable $name which is fed a value from $_POST['name'] from a form field. Now this form field is limited in the HTML to accept only 20 characters, but someone could easily edit the form or outgoing post data. So I want to know how to limit the variable size in the script. In other languages it could be something like this: var name(20). So how do I do that in PHP? Hi. I want to create a list of files in a directory. But I don't want all the files to be listed, only .gif, .jpg and .bmp. Does anyone know the PHP code how to do that? (My directory name is 'images' if you need that). Thanks! I have created a table called directories. Now basically I have two fields; dirID (INT) directory (VARCHAR) now I am fully aware this might sound like more of an SQL question but I have three physical directories: db/images/web1 db/images/web2 db/images/web3 I have inputted them into the database but I was just wondering, how could I created a page which links those records to a directory. I want to have each row hyperlinked, with the output page displaying list of contents for each directory. How can I possibly achieve this please? How to attach any file type to an email using php mail() It should attach any file that you select. What would be the Content-type: value? Thanks! I have a Windows-style ini file that contains entries as such:
[Timers] Timer(1)=50 Timer(2)=30 Timer(3)=20 The entries represent an array of 3 different timers Apparently parse_ini_file can't deal with the () format. Is there any way to use this format ini file without having to change how arrays are designated? Hey guys! I'm making a locally run web based application for entering/storing/editing data. I am trying to do this thing where I export a 'records.txt' file to a different location which can be selected by the user. I have a lame <input type='text' value='H:\'> box going on which I was going to use to define the path for the file to be saved, but I want to be able to use a pop up windows (or whatever native OS finder application) just like the one which appears when you use <input type='file'>. Now that I think about it, I think this is more of a html question, but it's 2.30am and my project is due today... See! what the hell, I just habitually pressed ctrl-s after working in dreamweaver for hours and the exact function which I am looking for popped up, how do I do that?! Please thanks guys Hello, Iv written a small script in JS to add input boxes of the type file to the page.. My problem is when i use multiple of those input boxes and submit the form the $_FILES variable only reads 1 of those boxes.. This is the javascript im using: Code: [Select] function addImageBox() { var imageBoxes = document.getElementById("imageBoxes"); var tr = document.createElement("tr"); var td = document.createElement("td"); var td2 = document.createElement("td"); var inputFile = document.createElement("input"); inputFile.setAttribute("type", "file"); inputFile.setAttribute("name", "image[]"); inputFile.setAttribute("style", "width: 450px"); td.appendChild(document.createTextNode("Image")); td2.appendChild(inputFile); tr.appendChild(td); tr.appendChild(td2); imageBoxes.appendChild(tr); } When i add 2 boxes (making it 3 boxes on the page in total) and count the $_FILES var after submiting the form, the count method returns 1, and when i var_dump it only 1 array is in $_FILES. Any idea's? thanks! hi there, i am fairly new to OOPs in php, i get an error when i declare the argument type (as object) in a function and pass the same type (object). class eBlast { public static function getEmail(object $result) { return $result->email; } } $r = mysql_fetch_object($query); eBlast::getEmail($r); echo gettype($r); // outputs: object error is : Code: [Select] Catchable fatal error: Argument 1 passed to eBlast::getEmail() must be an instance of object, instance of stdClass given, called in C:\wamp\www\integra\client\pl_eblast\admin\send_emails.php on line 145 and defined in C:\wamp\www\integra\client\pl_eblast\app\app.eBlast.php on line 8 if i remove the type declaration in the function it works, but just would like to know why it shows error when pass the same type, also isnt mysql_fetch_object is the instance of stdclass? thanks in advance! Probably a stupid question . . .
The MIME type in my php.ini file is set to text/html:
default_mimetype = "text/html"But, because I use XHTML 1.0 Strict, the MIME type of my web pages is set to text/xml: <meta http-equiv="content-type" content="text/xml; charset=utf-8" />I should therefore change the php.ini MIME type to text/xml, right? Hello friends, if i've database table (mytable) has the following ids 1 2 3 4 5 6 and i want to get it with limit the first (1 to 3 ) only Code: [Select] $sql ="select * from mytable LIMIT 3"; this will show the first 3 (1,2,3) how then i write code that shows which is after 3 so it shows me 4 5 6 and if there any way i can say Code: [Select] $sql ="select * from mytable LIMIT (first half of ids)"; and (shows 1,2,3..ect till half) Code: [Select] $sql ="select * from mytable LIMIT (second half of ids)"; will (shows 4,5,6...ect till end) thank you im using the floowing code to pull all alerts from the database. as you can see i have 3 types of alertsd. Profile alerts, forum alerts and topic alerts. They are sorted and placed on the screen under their respective header. However i want to limit it so it only displays 4 of each type of alert. I cant use LIMIT in the query because that would limit all alerts meaning only 4 alerts in total would show up and i just need to limit each alert type. any ideas? $alert_query = $link->query("SELECT a.a_aid, a.a_alert_type, a.a_time_alerted, a.a_fid, a.a_poster, a_alert_read, a.a_tid, c.f_name as cat_name, f.f_fid, f.f_name, t.t_name, u.u_avatar, u.u_avatar_cropped FROM ".TBL_PREFIX."alerts as a LEFT JOIN ".TBL_PREFIX."forums as f ON (f.f_fid = a.a_fid) LEFT JOIN ".TBL_PREFIX."topics as t ON (t.t_tid = a.a_tid) LEFT JOIN ".TBL_PREFIX."forums as c ON (c.f_fid = f.p_id) LEFT JOIN ".TBL_PREFIX."users as u ON (u.u_username = a.a_poster) WHERE a.a_user_name = '$user_name' ORDER BY a_time_alerted ") or die(print_link_error()); $alert_info = $alert_query->fetchAll(); $pm_alert_list = ''; $num_pm_alerts = 0; $num_forum_alerts = 0; $num_topic_alerts = 0; foreach($alert_info as $key => $val) { $alert_info[$key]['a_alert_read'] == 0 ? $color = '#f5dfaf' : $color = '#f4f4f4'; // if alert is a profile message alert if($alert_info[$key]['a_alert_type'] == 1) { $pm_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $pm_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" />'.profile_link($alert_info[$key]['a_poster']).' posted on your wall</p>'; $pm_alert_list .= '<p class="alert_time"> on '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $pm_alert_list .= '</dd>'; $num_pm_alerts++; } if($alert_info[$key]['a_alert_type'] == 2) { $forum_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $forum_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" /><strong><a href="'.$config['asf_root'].'category/'.create_url($alert_info[$key]['cat_name']).'/forum/'.create_url($alert_info[$key]['f_name']).'">'.$alert_info[$key]['f_name'].'</a></strong> has a new topic</p>'; $forum_alert_list .= '<p class="alert_time"> '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $forum_alert_list .= '</dd>'; $num_forum_alerts++; } if($alert_info[$key]['a_alert_type'] == 3) { $topic_alert_list .= '<dd style="background:'.$color.';" class="alert" id="alert-'.$alert_info[$key]['a_aid'].'"><p class="alert_intro">'; $topic_alert_list .= '<input type="checkbox" class="pm_checkbox" id="pm_checkbox-'.$alert_info[$key]['a_aid'].'" /><strong><a href="'.$config['asf_root'].'category/'.create_url($alert_info[$key]['cat_name']).'/forum/'.create_url($alert_info[$key]['f_name']).'/topic/'.create_url($alert_info[$key]['t_name']).'">'.$alert_info[$key]['t_name'].'</a></strong> has a new post</p>'; $topic_alert_list .= '<p class="alert_time"> '.asf_date($alert_info[$key]['a_time_alerted'],'full').'</p>'; $topic_alert_list .= '</dd>'; $num_topic_alerts++; } } This code works fine without the LIMIT 5, but it lists all the results. With the LIMIT Code: [Select] $query = 'SELECT * FROM wp_playerRank WHERE year="2011" LIMIT 5 ORDER BY rankClass ASC'; $results = mysql_query($query); while($line = mysql_fetch_assoc($results)) { Here is the error I'm getting: Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/jwrbloom/public_html/resources/players/rank2011_top5.php on line 26 |
