PHP - Max Width Or Height For Image Upload

Hi there. How can i set up a maximum width and height of a picture?

For example: the limit is 400x400. So if the photo is 200x200 then it stays that way, however if a photo is 550x550 then it gets resized to 400x400.

Hi People. 

Thanks for all the help on here in the past, you have been brilliant.

I run the airfield cards.com website and have a script in the output page that is as follows.
Code: [Select]
To Embed this Card into your website, cut and paste the following code: <input name="generate" value="<? echo "<iframe  src='http://www.airfieldcards.com/php/courtesy_card.php?id=".$id. "' ></iframe>";?>">
Now the way it shows on the site is like this
Code: [Select]
<iframe  src='http://www.airfieldcards.com/php/courtesy_card.php?id=165' ></iframe>
So, I look at the iframe code from google that should be cut and pasted into a website (obviously it's working code from google)
Code: [Select]
<iframe width="700" height="1500" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.co.uk/maps/ms?msa=0&amp;msid=203054009368331462137.0004aa731e7de2e86a0e0&amp;ie=UTF8&amp;t=h&amp;vpsrc=0&amp;ll=53.800651,-4.042969&amp;spn=80.03397,61.435547&amp;z=4&amp;output=embed"></iframe><br /><small>View <a href="http://maps.google.co.uk/maps/ms?msa=0&amp;msid=203054009368331462137.0004aa731e7de2e86a0e0&amp;ie=UTF8&amp;t=h&amp;vpsrc=0&amp;ll=53.800651,-4.042969&amp;spn=80.03397,61.435547&amp;z=4&amp;source=embed" style="color:#0000FF;text-align:left">AirfieldCards.com</a> in a larger map</small>
Now I have tried to take the code from the google iframe (width/height/scrolling/etc) and paste it into my source but it doesn't work.

Here's how I have done it.
Code: [Select]
To Embed this Card into your website, cut and paste the following code: <input name="generate" value="<? echo "<iframe  width="700" height="1500" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src='http://www.airfieldcards.com/php/courtesy_card.php?id=".$id. "' ></iframe>";?>">
Can someone please modify my fist lot of code so that I have the correct height and width settings (700 x 1500)

Thanks in advance

Hi folks,

I'm using this code to display a picture that is uploaded in a form.

Code: [Select]

print "<img src='http://www.coast2kosci.com/mylongrun/test/photo_uploads/$imgx' width='300' height='300'  alt='Your photo' />";


At first I tried specifying only the width, without the height. But for tall photos, the display wasn't really what I was after.

Then I specified both width and height, which results in a mis-scaled photo.

Is there any way that I can specify the height and width atributes as a sort of maximum / or limiter. Ie:  If the height is greater than the width, limit the height to 300, and if the width is greater than the height, limit the width to 300?

Thanks for your time,

Dave

Hi
Im working on a market place style website. the framework im using is called elgg. it uses an algoritm to find the right approximate width and height of an image thats being uploaded. but on my site, all heights and widths must be the same. this is difficult because some pictures have much greater width than height and some have much greater height. so whats the best algoritm to use to make an accurate thumbnail of all images uploaded?
Thanks

How can i edit just one image at on time with a multiple image upload form? I have the images being stored in a folder and the path being stored in MySQL. I also have the files being uploaded with a unique id. My issue is that I want to be able to pass the values of what is already in $name2 $name3 $name4 if I only want to edit $name1. I don't want to have to manually update the 4 images. Here is the PHP:
Code: [Select]
<?php

require_once('storescripts/connect.php');
mysql_select_db($database_phpimage,$phpimage);
$uploadDir = 'upload/';
if(isset($_POST['upload']))
{


foreach ($_FILES as $file)
{

    $fileName = $file['name'];
    $tmpName = $file['tmp_name'];
    $fileSize = $file['size'];
    $fileType = $file['type'];

    if ($fileName != ""){
        $filePath = $uploadDir;
        $fileName = str_replace(" ", "_", $fileName);

        //Split the name into the base name and extension
        $pathInfo = pathinfo($fileName);
        $fileName_base = $pathInfo['fileName'];
        $fileName_ext = $pathInfo['extension'];

        //now we re-assemble the file name, sticking the output of uniqid into it
        //and keep doing this in a loop until we generate a name that 
        //does not already exist (most likely we will get that first try)
        do {
           $fileName = $fileName_base . uniqid() . '.' . $fileName_ext;
        } while (file_exists($filePath.$fileName));

$file_names [] = $fileName;

        $result = move_uploaded_file($tmpName, $filePath.$fileName);
    }


if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
$filePath = addslashes($filePath);
}
$fileinsert[] = $filePath;
}
}

$mid   = mysql_real_escape_string(trim($_POST['mid']));
$cat   = mysql_real_escape_string(trim($_POST['cat']));
$item  = mysql_real_escape_string(trim($_POST['item']));
$price = mysql_real_escape_string(trim($_POST['price']));
$about = mysql_real_escape_string(trim($_POST['about']));

$fields = array();
$values = array();

for($i = 0; $i < 4; $i++)

    if($values[$i] != '') {
        $updateVals[] = 'name' . ($i + 1) . " = '{$values[$i]}'"; 
    }

}

$update = "INSERT INTO image
               (mid, cid, item, price, about, name1, name2, name3, name4)
           VALUES
               ('$mid', '$cat', '$item', '$price', '$about', '$values[0]', '$values[1]', '$values[2]', '$values[3]')
           ON DUPLICATE KEY UPDATE

Hello

I am having problems uploading an image through a HTML form. I want the image to be uploaded to the server and the image name to be written to the mysql database.

Below is the code I am using:
Code: [Select]
<?php
if (isset($_POST['add'])){
   
   echo "<br /> add value is true";
      $name = $_POST['name'];   
      $description = $_POST['description'];   
      $price = $_POST['price'];
      $category_id = $_POST['category_name'];
      $image = $_FILES['image']['name'];   
      
      //file path of the image upload
      $filepath = "../images/";
      //mew name for the image upload
      $newimagename = $name;
      //new width for the image
      $newwidth = 100;
      //new height for the image
      $newheight = 100;
      
      include('../includes/image-upload.php');
      
      
      mysql_query("INSERT INTO item (item_name, item_description, item_price, item_image)
      VALUES ('$name','$description','$price','$image')"); ?>

Here is the image-upload.php file code:

Code: [Select]
<?php

//assigns the file to the image
$image =$_FILES["image"]["name"];
$uploadedfile =$_FILES["image"]["tmp_name"];

if ($image) {
   //retrieves the extension type from image upload
   $extension = getextension($image);
   //converts extension to lowercase
   $extension = strtolower($extension);
   
   //create image from uploaded file type
   if($extension=="jpg" || $extension=="jpeg") {
      $uploadedfile = $_FILES['image']['tmp_name'];
      $src = imagecreatefromjpeg($uploadedfile);
   }else if($extension=="png") {
      $uploadedfile = $_FILES['image']['tmp_name'];
      $src = imagecreatefrompng($uploadedfile);
   }else{
      $src = imagecreatefromgif($uploadedfile);
   }
   
   //creates a list of the width and height of the image
   list($width,$height)=getimagesize($uploadedfile);
   
   //adds color to the image
   $tmp = imagecreatetruecolor($newwidth,$newheight);
   
   //create image
   imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
   
   //set file name
   $filename = $filepath.$newimagename.".".$extension;
   $imagename = $newimagename.".".$extension;
   //uploads new file with name to the chosen directory
   imagejpeg($tmp,$filename,100);
   
   //empty variables
   imagedestroy($src);
   imagedestroy($tmp);
   
}


?>
Any help would be appreciated, fairly new to all this!

Thanks!!!

I have a working image upload script that uploads, renames the file and adds filename to the database.

is it possible to include some sort of image resize code? if so can anyone point me in the right direction or better still show some example code and explain how it works etc.

below is my working code:

$errors = array();

$fileBaseName = substr($fileName, 0, strripos($fileName, '.'));

   // Get the extension from the filename.
   $ext = substr($fileName, strpos($fileName,'.'), strlen($fileName)-1);

Many thanks to phpfreaks again.

hello friends,

while clicking the form all the information goes to database, I have one image upload field,
when cliking the submit button, i would like 'image name' to go in database and file to go in
/upload folder, i have tried this for hours and gave up,

if anyone help me in this, i would be very greatful

Hi,

Im rather new to php and really unable to get the above to work. Everything works apart from the image being resized. File is uploaded, and the image name is printed into the SQL database. But i cant for the life of me get the image to go to 300x200? If you could help me i would be very grateful

My code for the form processing page is attached. Ive put a few line breaks into the code as to where i think is the issue. I just cant seem to resize the image. Does the image resize need to come before the part it writes the image to the server or can this be done afterwards? Please help.

P.S - Thanks in advance

I need code for upload images for php as well as to edit that image

Hello everyone.i'm beginner in programming.How to make page that user can upload their own image..

Hi everybody, I have similar problem like member vikaspa in this thread:

http://www.phpfreaks.com/forums/index.php?topic=279531.msg1323820#msg1323820

Have great site, but this image rewriting makes me crazy...today someone upload  in some thread 1.jpg for example...after 3 days someone uploads diferent image and also called it 1.jpg, and overwrites this earlier one. Nonsense.

Please help me with my code, what to add where, to prevent rewriting and instead that, to rename upload internally (without notifying the user)...for example 1_1.jpg.

Here is my code:

Code: [Select]
if ($fdata['forum_attach'] && checkgroup($fdata['forum_attach'])) {
$attach = $_FILES['attach'];
if ($attach['name'] != "" && !empty($attach['name']) && is_uploaded_file($attach['tmp_name'])) {

$attachext = strtolower(strrchr($attach['name'],"."));
if (preg_match("/^[-0-9A-Z_\[\]]+$/i", $attachname) && $attach['size'] <= $settings['attachmax']) {

} else {
@unlink($attach['tmp_name']);
$error = 1;
}
} else {
@unlink($attach['tmp_name']);
$error = 2;
}

Thanx in advance, sorry for longer thread, and for my english. Regards. 

I have absolutely no idea how to allow users to upload their own avatars and then have the file save as their user ID (uID), and if the uID already exists, then have it overwrite it.

does anyone know a good open source image upload with info upload  basically upload a image to a dir and submitt the info like $date $title $who  to a DB

Thanks in advance
