Absorbator

Thanks for the answer. I played a little with the model/view scripts (or controllers) and I found that it is not so hard to customize opencart.

I'm looking for a eCommerce software that can be customized easily. So far I've tried OpenCart but I find it unnecessarily complex and very clumsy in terms of customization. I can't even get rid of the demo products !!! I need an application or a library that simply does its server-side job and allows me to easily customize it with scripts (I have a long experience with PHP, so that's not a problem). Any recommendations are appreciated

The object must passed in recursive function, but JavaScript complains that such an operation is invalid function fadeIn(el, val){ if(val>=1) return; document.getElementById(el).style.opacity=val; setTimeout("fadeIn(" + el + ", " + (val+0.1) + ")", ; }

Hi everybody! I have a JavaScript function which has to be applied to many objects. The problem is that a variable used as an argument for getElementById() is changed to something like "[object HTMLDIVElement]" and it becomes useless. I have to use the variable several times with no changes. Thanks in advance!

I'm wondering are MySQL tables more efficient than normal files in the matter of performance. I know that MySQL stores tables in files, but I still don't know which one to prefer - to store my data in MySQL tables or in "regular" files?

Debian sounds good. Thanks both of you!

Hi everybody! I have an old i686 (Pentium 3 1GHz, 512mb RAM) and I want to turn it into server. Since the machine is really slow I want to use some minimized Operating System. I tried with Damn Small Linux, but it lacks too many things (some of which very important like gcc and make ) and I don't want to waste weeks of my life trying to configure the damn server. The PC is going to serve some sites with PPC advertisement - something like 30-40 impressions per seccond, but most of the time may be 2 to 4 times less. So I need something light (the GUI may be absent ) but still to have enough software out of the box. Thanks in advance

Hi, I try to install Roadsend php compiler but I can't. When I type ./configure and then make the shell returns "make: *** No targets specified and no makefile found. Stop. ". I thought I can use other compilers but they are even more weird. My OS is OpenSUSE 11. I can't figure out where is the problem. The install instructions in Roadsend website are very confusing...

I had similar problem, several months ago. Probably different character encoding in your database and your script is causing the problem

Did you try tables?

I thought addslashes() works fine...

Hi, I would like to resize GIF animation while keeping its frames and properties. How can I do that in PHP?

First - $HTTP_POST_VARS is deprecated, use $_POST instead Second - $HTTP_POST_FILES should be $_FILES Third - PHP interprate white space string as FALSE <?php$error=" "; //this is false ?>

Yes, you cannot use a cookie that is set at the current session.

You have left the braces from the md5 function. Remove them <?phpif(isset($_POST[submit])){ $imgNumb=1; //This the "pointer" to images $DestinationDir="images/"; //Place the destination dir here $LargeDir="images/"; //Place the large image dir here do{ $Unique=$_FILES['img$imgNumb']['name']; // We want unique names, right? $destination=$DestinationDir.$Unique.".jpg"; $thumb=$ThumbDir.$Unique.".jpg"; $IMG=getimagesize($_FILES["img$imgNumb"][tmp_name]); echo resize($_FILES["img$imgNumb"][tmp_name], $IMG[0], $destination); echo resize($_FILES["img$imgNumb"][tmp_name], 120, $thumb); //That was what I forgot last time $imgNumb++; } while($_FILES["img$imgNumb"][name]); } ?>

Your way (just "echo") should be faster. Storing data in a variable takes time too... ---------------- Now playing: Metallica - Sad but True via FoxyTunes

"$session->isAdmin()" means that you have already created a variable (object) called $session of some class you declared somewhere (probably in the included file). If this is not the case, try just "isAdmin()" Edit: Try using the global array to access your objects like $GLOBALS['session'] ---------------- Now playing: Metallica - Don't Thread on Me via FoxyTunes

I think you just have to translate your data into utf-8 string like: <?php $theText = utf8_encode($_POST['text']); $query = mysql_query("INSERT INTO `text_table` (`text`) VALUES (' $theText ') "); $fileHandle = fopen("file.txt", "wb"); fwrite($fileHandle, $theText); fclose($fileHandle); ?> ---------------- Now playing: D-Phrag - Deep Transmissions Part 3 via FoxyTunes

I recommend you to change your HTML code because I really don't like name-unspecified variables <form action="" method="post" enctype="multipart/form-data" > <input type="file" name="img1"/> <input type="file" name="img2"/> <input type="file" name="img3"/> <input type="submit" name="submit" value="Submit"/> </form> I'm using modified version of a function I found at http://php.net. But I can't remember where is it. So, you could use thins function which I found at http://bg2.php.net/manual/en/function.imagecreatefromjpeg.php (Posted by Ninjabear) <?php function resize($img, $thumb_width, $newfilename) { $max_width=$thumb_width; //Check if GD extension is loaded if (!extension_loaded('gd') && !extension_loaded('gd2')) { trigger_error("GD is not loaded", E_USER_WARNING); return false; } //Get Image size info list($width_orig, $height_orig, $image_type) = getimagesize($img); switch ($image_type) { case 1: $im = imagecreatefromgif($img); break; case 2: $im = imagecreatefromjpeg($img); break; case 3: $im = imagecreatefrompng($img); break; default: trigger_error('Unsupported filetype!', E_USER_WARNING); break; } /*** calculate the aspect ratio ***/ $aspect_ratio = (float) $height_orig / $width_orig; /*** calculate the thumbnail width based on the height ***/ $thumb_height = round($thumb_width * $aspect_ratio); while($thumb_height>$max_width) { $thumb_width-=10; $thumb_height = round($thumb_width * $aspect_ratio); } $newImg = imagecreatetruecolor($thumb_width, $thumb_height); /* Check if this image is PNG or GIF, then set if Transparent*/ if(($image_type == 1) OR ($image_type==3)) { imagealphablending($newImg, false); imagesavealpha($newImg,true); $transparent = imagecolorallocatealpha($newImg, 255, 255, 255, 127); imagefilledrectangle($newImg, 0, 0, $thumb_width, $thumb_height, $transparent); } imagecopyresampled($newImg, $im, 0, 0, 0, 0, $thumb_width, $thumb_height, $width_orig, $height_orig); //Generate the file, and rename it to $newfilename switch ($image_type) { case 1: imagegif($newImg,$newfilename); break; case 2: imagejpeg($newImg,$newfilename); break; case 3: imagepng($newImg,$newfilename); break; default: trigger_error('Failed resize image!', E_USER_WARNING); break; } return $newfilename; } //This stuff is outside of the function. It operates with our images if(isset($_POST[submit])){ $imgNumb=1; //This the "pointer" to images $DestinationDir="images/"; //Place the destination dir here $ThumbDir="images/thumb_"; //Place the thumb dir here do{ $Unique=microtime(); // We want unique names, right? $destination=$DestinationDir.md5($Unique).".jpg"; $thumb=$ThumbDir.md5($Unique).".jpg"; $IMG=getimagesize($_FILES["img$imgNumb"][tmp_name]); echo resize($_FILES["img$imgNumb"][tmp_name], $IMG[0], $destination); $imgNumb++; } while($_FILES["img$imgNumb"][name]); } ?> Hope this finally works

Didn't you try mysql_fetch_array() function?

Don't use $q in mysql_num_rows as it would cause always the same results. Instead use $r["votes"], assuming that you have a field named votes which stores number of votes... This should works

Well, I created the code only as an example, however, do you have imgs and imgs/thumbs directories. If they don't exist, PHP wouldn't create them, so you need to create them manually. Try again and tell us if you have more problems

About the substract - yes, this tableName SET Coins=Coins-1 is valid. About the "on click" part - The takeDiamond function you provided is not bad. Try this: <?php function takeDiamond() { $query=mysql_query("SELECT * FROM tableName WHERE userName=$User"); $fetch_query=mysql_fetch_array($query); $diamond = fetch_query["coins"]; if ($diamond > 0) { $diamond--; //Or $diamond++; if you want to add coins if(mysql_query("UPDATE tableName SET coins='$diamond' WHERE userName=$User")) //Remember, I use userName field, but you can use any other field names return true; else return false; } else { return false; } ?> Then call the function on the beginning of the files you need. But remember this - You have to specify the User Name as it is required by the function. You can pass it as an argument to the function or refer to the Variable that holds user name or id as a GLOBAL variable like: <?php function takeDiamond() { $User = $GLOBALS["User"]; //This is the new thing.The "User" between "[" and "]" is name of a global variable (means that is outside the function). Replace it with the name of the actual variable that holds user name or user id $query=mysql_query("SELECT * FROM tableName WHERE userName=$User"); $fetch_query=mysql_fetch_array($query); $diamond = fetch_query["coins"]; if ($diamond > 0) { $diamond--; //Or $diamond++; if you want to add coins if(mysql_query("UPDATE tableName SET coins='$diamond' WHERE userName=$User")) //Remember, I use userName field, but you can use any other field names return true; else return false; } else { return false; } ?> One more thing - you have to call mysql_query function as well as mysql_select_db in order to use takeDiamond without errors Tell us if you get problems...

Actually yes, it is. I used it because I didn't know what field names do you have, so feel free to replace it with your index field name. The WHERE clause, tells MySQL which rows to update and if you ignore it, MySQL will update all rows in your table, which is not what you want, do you?

First of all you can upload only ONE file per input field, so the very first thing you should do is to create more input fields in your HTML code. I recommend you to name them with numeric values, as it would be easier to access them via PHP, like: img1, img2, img3, etc. So the HTML would be like this <form action="upload.php" method="post" enctype="multipart/form-data" > <input type="file" name="img1"/> <input type="file" name="img2"/> <input type="file" name="img3"/> <input type="submit"/> </form> then in the PHP code, create a function that resize the image. I will create a while loop, to access each of the images: <?php function imgReisize($uploadedfile, $Destination, $Thumb){ //this is the function that will resize and copy our images // Create an Image from it so we can do the resize $src = imagecreatefromjpeg($uploadedfile); // Capture the original size of the uploaded image list($width,$height)=getimagesize($uploadedfile); // For our purposes, I have resized the image to be // 600 pixels wide, and maintain the original aspect // ratio. This prevents the image from being "stretched" // or "squashed". If you prefer some max width other than // 600, simply change the $newwidth variable $newwidth=600; $newheight=($height/$width)*600; $tmp=imagecreatetruecolor($newwidth,$newheight); // this line actually does the image resizing, copying from the original // image into the $tmp image imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height); // now write the resized image to disk. I have assumed that you want the // resized, uploaded image file to reside in the ./images subdirectory. $filename = $Destination; imagejpeg($tmp,$filename,100); // For our purposes, I have resized the image to be // 150 pixels high, and maintain the original aspect // ratio. This prevents the image from being "stretched" // or "squashed". If you prefer some max height other than // 150, simply change the $newheight variable $newheight=150; $newwidth=($width/$height)*150; $tmp=imagecreatetruecolor($newwidth,$newheight); // this line actually does the image resizing, copying from the original // image into the $tmp image imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height); // now write the resized image to disk. I have assumed that you want the // resized, uploaded image file to reside in the ./images subdirectory. $filename = $Thumb; imagejpeg($tmp,$filename,100); imagedestroy($src); imagedestroy($tmp); // NOTE: PHP will clean up the temp file it created when the request // has completed. echo "Successfully Uploaded: <img src='".$filename."'>"; } if(isset($_POST[submit])){ $imgNumb=1; //This the "pointer" to images $DestinationDir="./imgs/"; //Place the destination dir here $ThumbDir="./imgs/thumbs/"; //Place the thumb dir here while($_FILES["img".$imgNumb][tmp_name]){ $Unique=microtime(); // We want unique names, right? $destination=$DestinationDir.md5($Unique).".jpg"; $thumb=$ThumbDir.md5($Unique).".jpg"; imgReisize($_FILES["img".$imgNumb][tmp_name], $destination, $thumb); $imgNumb++; } } ?>
