PHP - Create An Image Of A Document When It Is Uploaded

Hello

I have uploaded images from a server onto a website, they run through a mysql database (database holds the image file names). The problem I am having is resizing the images. Can anyone help?

Thank you in advance

GWG

I'm beginning with simple codes to understand how things work and work my way up with what I need.

My upload form looks like this:

<form name="upload about" action="display.php" enctype="multipart/form-data" method="post">
Header: <input type="text" name="header" />
Body: <input type="text" name="body"  />
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
Image: <input type="file" name="pic"  />
<input type="submit" />
</form>

And my display page is just as simple.

<?php echo $_POST["header"]; ?>
<?php echo $_POST["body"]; ?>
<?php echo $_FILES['pic']['name']; ?>

The problem is, whenever I submit the data, everything is fine, except the image does not display and just posts the filename of the image I uploaded.
According to my research setting the enctype to multipart/formdata should display the image, but it does not. Can anyone tell me what's wrong?

OK,

When the user fills the info in the form out it goes in the DB fine.  I can then array them on the "showroom page" fine.

When they upload a picture it goes into the /images/ folder fine.

Problem is... On each array on the showroom page I need the image they uploaded to be displayed.

Cant work it out.

Help would be GREAT!!!!!

hi to all.Im currently displaying the images from my upload directory but the image does not display.please help thanks

Hey guys!
I have the following php code that grabs variables (and the browsed image) from Flash.


//FLASH VARIABLES
$Name = $_POST['Name'];
$itemNumber = $_POST['itemNumber'];
$filename = $_FILES['Filedata']['name'];
$filetmpname = $_FILES['Filedata']['tmp_name'];
$fileType = $_FILES["Filedata"]["type"];
$fileSizeMB = ($_FILES["Filedata"]["size"] / 1024 / 1000);


list($filename, $extension) = explode('.', basename($_FILES['Filedata']['name']));
$filename = $Name;
$target = $filename . $itemNumber . "." . $extension;


// Place file on server, into the images folder
move_uploaded_file($_FILES['Filedata']['tmp_name'], "images/".$target);



This works perfect, but what I want to change is the width and height of the uploaded image.
Any ideas/suggestions on how this could be done?

Thanks in advance!!
Cheers!

Hi

Basically I've built a CMS where by my clients can upload a number of images. On the success page I want to display the images they uploaded by file name.

The issue is the number of images can vary. They may upload 2 or 10 or 50 etc.

So far I've come up with this:

Code: [Select]
// number of files
$UN = 3; //I've set this to 3 for now, but this is passed from the upload page!

// server directories and directory names
$dir = '../properties';

$images = glob($dir.'/*.{jpg}', GLOB_BRACE); //formats to look for

$num_of_files = $UN; //number of images to display from number of uploaded files

foreach($images as $image)
{
$num_of_files--;

$newest_mtime = 0;
$image = 'BROKEN';
if ($handle = @opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != '.') && ($file != '..')) {
$mtime = filemtime("$dir/$file");
if ($mtime > $newest_mtime) {
$newest_mtime = $mtime;
$image = "$file";
}
}
}
}

if($num_of_files > -1) //this made me laugh when I wrote it
echo $trimmed = ltrim($image, "../properties").'<br />'; //display images
else
break;
}
Without this piece of code:

Code: [Select]
$newest_mtime = 0;
$image = 'BROKEN';
if ($handle = @opendir($dir)) {
while (false !== ($file = readdir($handle))) {
if (($file != '.') && ($file != '..')) {
$mtime = filemtime("$dir/$file");
if ($mtime > $newest_mtime) {
$newest_mtime = $mtime;
$image = "$file";
}
}
}
}
It shows the first 3 files alphabetically. I want to view the last number of images added.

With the above code it simply shows the last image added 3 times!

So I need to get the time each image was added and then order by the newest added and limit to the number of images uploaded. Any suggestions please?

Kindest regards
Glynn

I need help making the uploaded image file name, that's chosen to be uploaded, be displayed on the html page with the path /upload/ added to the beginning of the displayed file name like so:
../upload/test.png
Any help/improvements will be appreciated.

<html>
 <head>
  <title>PHP Test</title>
 </head>
  <body>
 <?php
 if ($form_submitted == 'yes') {
 $allowedExts = array("gif", "jpeg", "jpg", "png");
 $temp = explode(".", $_FILES["file"]["name"]);
 $extension = strtolower( end($temp) );
 if (  $_FILES["file"]["size"] < 200000
       && in_array($extension, $allowedExts) )
 {
     if ($_FILES["file"]["error"]!= 0)
     {
         echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
     } else {
         $length = 20;
         move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $newfilename );
         $file_location = '<a href="http://../upload/' . $newfilename . '">' . $newfilename . '</a>';
     }
 } else {
   echo "Invalid upload file";
 }
?>
<label for="file">Filename:</label>
<input type="file" name="file" id="file">
</body>
</html>

Hi all

I am trying to write a piece of code to take an image, resize it and centre it on a canvas 300 pixels tall by 400 pixels high. I know I need to use imagecopymerged but how do I add it to the below code:

Code: [Select]
$imagelarge = $_FILES['image']['tmp_name'];
$imagelargemain = $_FILES['image']['name'];
$src = imagecreatefromjpeg($imagelarge);

list($width,$height)=getimagesize($imagelarge);
$newwidth=300;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);

$filename = WEB_UPLOAD."images/right-images/". $_FILES['image']['name'];
imagejpeg($tmp,$filename,100);
imagedestroy($src);
imagedestroy($tmp);

Many thanks for your help!

Hello

i just learned how to use .ttf fonts on a webpage ,but i noticed that IE Browsers arent supporting it
so i thought to make add the Fonted Text into a image so IE Browsers will see the font in a image and not a replaced font text

Could someone please provide me a Simple Script to make a PNG image with the text and font and a invisible background ?

Hi! my code uploads an image and saves it to an upload folder, but I want to create a thumbnail of it.

For example, if I upload a 1400x1000 JPG, I would like to resize the image and it has to respect the proportion given a maximum size.

if I say the maximum width/height is 250px, the image should be thumbnailed according to the max height/width, and in proportion with the width/height

Thanks in advance

Hi,

How to create an invisible text in an image. Any idea?

Thanks.

Here is the script the reads a twitter xml feed and generates a png from the first tweet. What I want to be able to is specify a width so the text will wrap and be able to position the text within a certain dimensions. I created the files with a base image because I didn't know how to create an image with a specific color. So removing the base image section would be great. Lastly, I would like to style the font with a certain font and weight.


<?php
// Get the XML data from Feedburner
$sxe = new SimpleXMLElement('twitter.xml', NULL, TRUE);
$tweet = $sxe->status[0]->text;
 
// Create the image from the base image
$img = imagecreatefrompng('tweet-base.png');
$color = imagecolorallocate($img, 0x33, 0x33, 0x33);
imagestring($img, 2, $xpos, 2, $tweet, $color);
 
// Save the image
imagepng($img, 'tweet.png');
?>

I need to upload an image using php and store the image as blob in mysql. I understand the standard way is to create a form for the user, let the user choose the image to upload, click submit.

But I need to create a php, for example, uploadImage.php?image="c:\myPhoto.jpg"
and when I type http:\\www.myhome.com\uploadImage.php?image="c:\myPhoto.jpg"
from a web browser in my pc, I can automatically upload myPhoto.jpg to the myhome.com server?

Thank you for your kind help.

 //image1
$nameone=$_FILES['myfileone']['name'];
$tmp_name= $_FILES['myfileone']['tmp_name'];
if ($nameone)

{
$locationone="images/$nameone";
