  • PHP: imagepng is creating inordinately large files

    - by Rafael
    I'm using a simple thumbnailing script I wrote and it's pretty standard: $imgbuffer = imagecreatetruecolor($thumbwidth, $thumbheight); switch($type) { case 1: $image = imagecreatefromgif($img); break; case 2: $image = imagecreatefromjpeg($img); break; case 3: $image = imagecreatefrompng($img); break; case 6: $image = imagecreatefrombmp($img); break; case 15: $image = imagecreatefromwbmp($img); break; default: return log_error("Tried to create thumbnail from $img: not a valid image"); } imagecopyresampled($imgbuffer, $image, 0, 0, 0, 0, $thumbwidth, $thumbheight, $width, $height); $output = imagepng($imgbuffer, "$album/thumbs/$imgname.png", 9); 9 is the lowest quality setting, yet from a 400 x 600 JPEG image (at 56kB) I'm getting a thumbnail 27 kB in size (140 x 140). Using imagejpeg (quality of 80) instead of imagepng it's about 4kB. How can this be, especially at the lowest quality setting for imagepng? I tried using imagecopy instead of imagecopyresampled, and imagecreate instead of the true color version. Unfortunately the images come out mangled somehow. Is there any way to get PNG thumbnails of a reasonably small file size (about 4 kB at 140 x 140)? Or do I have to use JPEG?

  • PHP Object Oriented Web Application

    - by Sev
    I have a class called "Layout" for the layout of the page, another class called "User" for the user. Every page I create, I instantiate a new Layout. When a user logs in, there is a new User instantiated. How do I get an instance of the layout class to know about the instantiated user? I could also save the entire instance of the User in a session variable. I assume that's a bad idea though. What are the best practices for this?

  • PHP Notice: Undefined index when looping array...

    - by Jonathan
    Hi, I'm looping a two-dimensional array like this: if (!empty($aka)) { foreach ($aka as $ak) { if($ak["lang"]=="es") { $sptitle=$ak["title"]; } } } Pretty simple. If the array ($aka) is not empty I loop trough it and when it finds that the "lang" index is equal to "es" I just save the "title" value for that index in $sptitle. The problem is that the array ($aka) contains a lot of information and sometimes there is no "lang" index... and I get this error: Notice: Undefined index: lang. How can I fix this??? This is a extract of the array to help you understand. Notice that [1] doesn't have a [lang] index but [2] does have: [1] =&gt; Array ( [title] =&gt; The Lord of the Rings: The Motion Picture [year] =&gt; [country] =&gt; USA [comment] =&gt; promotional title ) [2] =&gt; Array ( [title] =&gt; Señor de los anillos: La comunidad del anillo, El [year] =&gt; [country] =&gt; Argentina [comment] =&gt; Chile, Mexico, Peru, Spain [lang] =&gt; es ) Thanks!

  • PHP How to access constant defined outside class?

    - by Ashley Ward
    I have defined some constants eg: define('DB_HOSTNAME', 'localhost', true); define('DB_USERNAME', 'root', true); define('DB_PASSWORD', 'root', true); define('DB_DATABASE', 'authtest', true); now when I try to do this: class Auth{ function AuthClass() { $this->db_link = mysql_connect(DB_HOSTNAME, DB_USERNAME, DB_PASSWORD) or die(mysql_error()); } } I get an error. Why is this and what do I need to do? See, I've tried using (for example) global DB_HOSTNAME but this fails with an error.

  • PHP REMOTE_ADDR and secure sessions

    - by Christopher McCann
    One of the ways I have used to make securer sessions in the past is to also record the clients IP address and user agent at the handshake. Each time the client moves a page and calls session_start() I also check that the IP address and user agent stored is still the same to prevent hiijacking. But if someone is connecting from say a company network then all the users will probably have the same external static IP address and they could also really easily be using the same user agent. Is there other metrics I can use which are local only to the physical machine? Thanks

  • Input questions mysql php html

    - by Marcelo
    (Q1)Hi I'm using textbox in my project and I can't receive the values that are typed <textarea rows="5" cols="60"> Type your suggestion </textarea> <br> <input type="submit" name="sugestao" value="Submit" /> Sorry I don't know how to 'kill' html code, that's why < is missing. All I'm getting in the column of the database from this text box is "Submit", I'd like to receive whatever is written in the text area. How can I make the value equal whaterever is typed? (Q2) How can I make sure that I'll only store the same type(int,varchar,text) that I setted,declared in the database. For example: age(int), but if someone types "abc" in the input it will be stored in my database as the value 0 . How can I forbid this, and only save the age when it's just int and all the other fields(like name, email) are filled ?. And if is still possible warn the user that he is typing something wrong, don't need to say where. Sorry for any mistake in English and Thanks for the attention.

  • php and mysql user tracking and reporting

    - by inertiahz
    Hi, I currently have a table which consists of user information and lesson id; the table layout looks like: ---------------------------------------------------- |employeeID|numVisits|lessonID1|lessonID2|lessonID3| ---------------------------------------------------- |33388 |2 |1 |0 |3 | and a lessons table which contains the information about the lesson: ------------------------------------------------------ |lessonID |cateogry |title |filepath |numberviews| ------------------------------------------------------ |1 |beginner |lesson |file:// |10 | Within the lessonID fields in the user table is an integer which tracks how many times someone has clicked on a lesson. Now what I am trying to do is in a report I have the top 5 people who have visited the site and would like to then be able to drill down into what lessons they have clicked on. Can anyone help with this? Or would restructuring the way the database is be an easier task? Thanks

  • What is the right path for PHP includes on a Mac?

    - by skorned
    Running Mac OS X 10.5.8, with PHP 5.2.11 Pre-installed. Using Coda 1.6.10. I'm writing PHP files, and then preview them running from file, not server. This was working fine till I tried PHP includes. These don't work as a relative path, only as an absolute from the root of the drive. Is there any way I can use statements like include_once "common/header.php"; without specifying my entire file path like so : include_once "/Volumes/Macintosh HD/Users/neil/Desktop/Website/ColoredLists_v1.0/common/base.php"; ,where ColoredLists_v1.0 is the directory with all the website files in it. I tried solutions like prepending _SERVER[DOCUMENT_ROOT] or dirname(File) to the file paths, but that didn't work as the variables were not set. Is there any easy way to do this, or a configuration I can change so that it looks in a specific directory by default instead of looking at the drive root? Currently, echo_include_path shows .: When I include this line at the start of the script, it works: set_include_path('/Volumes/Macintosh HD/Users/neil/Desktop/Website/ColoredLists_v1.0'); However, if I want to do this for all my scripts, I can't seem to make the change permanent. Even after I edited the Unix include_path in my php.ini, it doesn't seem to work.

  • Use of date function in PHP to output a user-friendly date

    - by Jamie
    I have a MySQL database column named DateAdded. I'd like to echo this as a readable date/time. Here is a simplified version of the code I currently have: $result = mysql_query(" SELECT ListItem, DateAdded FROM lists WHERE UserID = '" . $currentid . "' "); while($row = mysql_fetch_array($result)) { // Make the date look nicer $dateadded = date('d-m-Y',$row['DateAdded']); echo $row['ListItem'] . ","; echo $dateadded; echo "<br />"; } Is the use of the date function the best way to output a user-friendly date? Thanks for taking a look,

  • strange array in php

    - by tunpishuang
    here i wrote a function , it's general purpose is to get an array of the depIds under the parent root $depId. i use recursion method to get the array. public function getEmpsByDep($depId){ $query = "select * from ".SQLPREFIX."department where id_parent=".$depId; $stmt=$this->db->query($query); while(($row=$this->db->fetch_assoc($stmt))==true) { if($this->hasChildNode($row['DEPID'])) { $depId = $row['DEPID']; self::getEmpsByDep($depId); } else { $arr[]=$row['DEPID']; } } return ($arr); } while i think it should return a 1D array of the depid.but it return a strange 2D array like this: array(4) { [0]=> string(2) "11" [1]=> string(2) "12" [2]=> string(2) "13" [3]=> string(2) "14" } array(3) { [0]=> string(2) "19" [1]=> string(2) "20" [2]=> string(2) "21" } array(3) { [0]=> string(2) "15" [1]=> string(2) "16" [2]=> string(2) "17" } array(8) { [0]=> string(1) "2" [1]=> string(1) "4" [2]=> string(1) "5" [3]=> string(1) "6" [4]=> string(1) "7" [5]=> string(1) "8" [6]=> string(1) "9" [7]=> string(2) "10" } here is the table structure and data sample: $query[]="create table ".$sqltblpre."department( depId number(10) not null primary key, depName varchar2(50) not null, id_parent number(10) )"; //department(?????) $index=1; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'??',0)"; //1 $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',0)"; //2 $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',0)"; //3 $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',0)"; //4 $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',0)"; //5 $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',0)"; //6 $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'?????',0)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'????',0)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'????',0)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'????',0)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'??',1)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'??',1)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',1)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'??',1)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'??',3)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',3)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',3)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',3)"; //18 $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'??',18)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'???',18)"; $query[] = "INSERT INTO ".$sqltblpre."department values(".$index++.",'??',18)"; so in a word, how can i get the 1D array thought the right code of this function?

  • SQL returns non-array value in PHP

    - by DeadMG
    $request = 'SELECT * FROM flight WHERE Id = \''.$_SESSION['LFLightRadio'].'\''; $data = mysql_fetch_array(mysql_query($request, $SQL)); echo '<table class="table">'; foreach($data as $key => $value) { echo '<th class="head" align="center" height="19">'.$key.'</th>'; } echo '<tr>'; foreach($data as $key => $value) { echo '<td class="cell" align="center" height="19">'.$value.'</td>'; } echo '</tr></table>'; I know that the LFlightRadio value is set, and is a value returned by the Id value of a previously returned row from the flight database. So within "flight", a record definitely exists with this Id. But, this still gives me a non-array result, so that when I try to use foreach on it, it errors out. Suggestions?

See File uploads below. * caption (optional, HTML allowed) * click-through-url (optional) I need to use data File uploads can be done in a data parameter where specified above. You may use either of the common encoding methods: multipart/form-data method, like a file upload box in a web form.

    I'm currently writing out xml and have done the following: header ("content-type: text/xml"); header ("content-length: ".strlen($xml)); $xml being the xml to be written out. I'm near about 1.8 megs of text (which I found via firebug), it seems as the writing is taking more time than the script to run.. is there a way to increase this write speed? Thank you in advance.

The problem is that the data is completed correctly on the form but the images are not uploaded. Can anyone help with advices/code/guidance?
