Manipulating uploaded images....

andy_b_1502 · March 15, 2012

Hi everyone,

I am after a scrpit/function that will get information of an uploaded image, resize it, then display the manipulated image.

in my "upload" script, there will be a size limit and a file extension/type limit to: 600 x 200px / jpg, gif, jpeg... this is to keep the script i'm after more simple. As using vector images i'm told is such a complicated problem for me at this time.

So...

to get the size info/dimensions its like this:

<?php

list($width, $height, $type, $attr) = getimagesize("image_name.jpg");

echo "Image width " .$width;
echo "<BR>";
echo "Image height " .$height;
echo "<BR>";
echo "Image type " .$type;
echo "<BR>";
echo "Attribute " .$attr;

?>

and..... resize something like this:

function get_image_sizes($sourceImageFilePath, 
  $maxResizeWidth, $maxResizeHeight) {

  // Get width and height of original image
  $size = getimagesize($sourceImageFilePath);
  if($size === FALSE) return FALSE; // Error
  $origWidth = $size[0];
  $origHeight = $size[1];

  // Change dimensions to fit maximum width and height
  $resizedWidth = $origWidth;
  $resizedHeight = $origHeight;
  if($resizedWidth > $maxResizeWidth) {
    $aspectRatio = $maxResizeWidth / $resizedWidth;
    $resizedWidth = round($aspectRatio * $resizedWidth);
    $resizedHeight = round($aspectRatio * $resizedHeight);
  }
  if($resizedHeight > $maxResizeHeight) {
    $aspectRatio = $maxResizeHeight / $resizedHeight;
    $resizedWidth = round($aspectRatio * $resizedWidth);
    $resizedHeight = round($aspectRatio * $resizedHeight);
  }
  
  // Return an array with the original and resized dimensions
  return array($origWidth, $origHeight, $resizedWidth, 
    $resizedHeight);
}

// Get dimensions
$sizes = get_image_sizes($sourceImageFilePath, $maxResizeWidth, 
  $maxResizeHeight);
$origWidth = $sizes[0];
$origHeight = $sizes[1];
$resizedWidth = $sizes[2];
$resizedHeight = $sizes[3];

// Create the resized image 
$imageOutput = imagecreatetruecolor($resizedWidth, 
    $resizedHeight);
if($imageOutput === FALSE) return FALSE; // Error condition

// Load the source image
$imageSource = imagecreatefromjpeg($sourceImageFilePath);
if($imageSource === FALSE) return FALSE; // Error condition

$result = imagecopyresampled($imageOutput, $imageSource, 
    0, 0, 0, 0, $resizedWidth, $resizedHeight, $origWidth, 
    $origHeight);
if($result === FALSE) return false; // Error condition

// Write out the JPEG file with the highest quality value
$result = imagejpeg($imageOutput, $outputPath, 100);
if($result === FALSE) return false; // Error condition

And.... display is this:

<?php 
$database="***"; 
mysql_connect ("***", "***", "***"); 
@mysql_select_db($database) or die( "Unable to select database"); 
$result = mysql_query( "SELECT company_name, location, postcode, basicpackage_description, premiumuser_description, upload FROM Companies" ) 
or die("SELECT Error: ".mysql_error()); 
$num_rows = mysql_num_rows($result); 
print "\n\n\nThere are $num_rows records.<P>"; 
echo "<table><tr><th>Comppany Name</th><th>Location</th><th>Postcode</th><th>Basic Members</th><th>Upgraded Users</th><th>Company Logo</th></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td></tr>";// store the records into $row array and loop through 
while ( $row = mysql_fetch_array( 
$result, MYSQL_ASSOC ) ) {
// Print out the contents of the entry  
echo "<tr><td>{$row['company_name']}</td>";
echo "<td>{$row['location']}</td>"; 
echo "<td>{$row['postcode']}</td>"; 
echo "<td>{$row['basicpackage_description']}</td>"; 
echo "<td>{$row['premiumuser_description']}</td>"; 

echo "<td><img src=\"http://www.removalspace.com/images/COMPANIES{$row['upload']}\" alt=\"logo\" /></td></tr>";} 
echo "</table>";
?>

How will all these fit together in one script? any help i'd love it! many thanks in advance

blacknight · March 15, 2012

first make a forum to upload the image

run upload script

on finish run resize

then display

andy_b_1502 · March 16, 2012

Thanks but i need help fitting all the pieces together, im not sure where each bit goes.

I have this upload and resize script but now iv'e modified it, it won't upload the image or resize?

What am i doing wrong? :confused:

this is what i end up with:

http://www.removalspace.com/index.php

note all the images different sizes.

andy_b_1502 · March 17, 2012

Any ideas??? :wtf: :wtf: :wtf:

SaCH · March 17, 2012

You need a basic idea about the coding.. Please follow my simple steps.

1. Create a html form to upload image file.

2. Get the image file

3. Get the size info/dimensions by using the uploaded image.

4. Resize it with your function

5. Display the image

andy_b_1502 · March 17, 2012

I have got the form

<form enctype="multipart/form-data" action="basicpackage-send.php" method="POST"> 
Compnany Name:<br /> <input type="text" name="company_name" id="company_name"><br> 
Company Description:<br /> <input type="text" name = "basicpackage_description" id="basicpackage_description"><br> 
Location:<br /> <input type="text" name = "location" id="location"><br> 
Postcode:<br /> <input type="text" name = "postcode" id="postcode"><br>
Company Logo/Photo:<br /> <input type="file" name="upload" id="upload"><br>

My question is, what is going wrong in this code to make it fail/ or why isnt this working? it only uploads the image BUT doesnt resize them.

Could you please shed some light on to this for me? it should work but it doesnt?

many thanks.

andy_b_1502 · March 17, 2012

it's not working, the resize function...?

litebearer · March 17, 2012

You have defined the function, but where have you 'called' the function?

print "\n\n\nThere are $num_rows records.<P>"; 
echo "<table><tr><th>Comppany Name</th><th>Location</th><th>Postcode</th><th>Basic Members</th><th>Upgraded Users</th><th>Company Logo</th></tr><tr><td></td><td></td><td></td><td></td><td></td><td></td></tr>";// store the records into $row array and loop through

echo "<td><img src=\"http://www.removalspace.com/images/COMPANIES{$row['upload']}\" alt=\"logo\" /></td></tr>";}

include resize_function? or select resize_function? :confused:

litebearer · March 18, 2012

NOT in the display section, but in the upload section (Look way down in the section that moves the image)...

ALSO, do your database inserting AFTER you have moved the image, otherwise, your table data may point to a non-existent image.

litebearer · March 18, 2012

you need to define/set the variables that the function uses.

if() defines the variable right? why am i getting an undefined variable error message litebearer?

guinbRo · March 18, 2012

Correct me if I'm missing a piece of PHP syntax, but in your last post the problem is that PHP thinks Resize_Image is a variable, and not a function as it truly is.

Fix it to be this:

if(Resize_Image($save,$file,$t_w,$t_h,$s_path,$o_path)) {
  //Notice that the '$' sign was removed
}

So going back to my question, why isnt it working when i define it???? lol

guinbRo · March 18, 2012

What are you declaring these variables to be? Do you think that the error may be revolving around this?

$save
$file
$t_w
$t_h
$s_path
$o_path

andy_b_1502 · March 18, 2012

yes... they are as part of my resize function

do i have to define each one??

Well yeah, your function can't work without the specified parameters. It looks like it wants, for example, a location where the image is at, the location where the new image will be placed, etc. Without passing these parameters the function won't work. So what I mean is that when you call the function, you have to be passing it the information it desires.

As i've posted the whole script previously; it knows where the image is, as the image is sent to the main folder then it resizes it. I thought that this piece of code here is "at the end" of the script that drops the image into the image folder.

So shouldnt it just do this:

1. Upload the image

2. Drop it into the folder

3. Resize it

4. Display newly re-sized image when called from server

"So what I mean is that when you call the function, you have to be passing it the information it desires."

What information should it need, thats preventing it from working at present?

if(Resize_Image($save,$file,$t_w,$t_h,$s_path,$o_path)) {  

//Notice that the '$' sign was removed

}

and is this all i need to define it? im slightly confused

The function takes six parameters:

$file is the name of the original image WITHOUT the path;

ie. $file = "newburg.jpg";

$save is the name of the resized image WITHOUT the path;

ie. $save = "newburg.jpg";

$t_w is the MAXIMUM width of the new image;

ie $t_w = 100;

$t_h is the MAXIMUM height of the new image;

ie $t_h = 100;

$o_path is the path to the original image INCLUDING the trailing slash; and

ie. $0_path = "/my_large/";

$s_path is the path where you want to save the new image INCLUDING the trailing slash.

ie. $s_path = "/my_thumbs/"

You MUST set these variables OUTSIDE the function BEFORE you call/use the function.

Isn't there a way of calling $file a generic name?

as i won't know the name of every file uploaded each time will i?? same with the resized image? it should be done all automatically shouldn't it?

  
$s_path = trim("/images/thumbs");	
$o_path = trim('images/COMPANIES');	
$save = $s_path . $save;	
$file = $o_path . $file;

$s_path = trim("/images/thumbs");	
$o_path = trim('images/COMPANIES');	
$save = thumbs . $save;	
$file = COMPANIES . $file;

:wtf: :-[

why the hell isn't this sinking in!? i just dont get this, im sorry! :shrug:

Step back, take a deep breath, then look at your existing code -

do you see where you created a variable containing the name of the image? hint: $upload

that would be your be your $file ie $file = $upload;

you can use the same name for the thumb/resized image if you are either (A) putting the thumb in a different folder than the original, or (b) overwriting the original

ALSO did you read the instructions regarding trailing slashes for the paths?

andy_b_1502 · March 18, 2012

Okay... so...

Ive now changed the paths to the original image, and for the thumbnails to read like this:


// RESIZE FUNCTION  */

function Resize_Image($save,$file,$t_w,$t_h,$s_path,$o_path)
  { 
  $s_path = trim("/images/thumbs");	
  $o_path = trim("images/COMPANIES");	
  $save = $upload . $save;	
  $file = $upload . $file;

Then is call the function like so:


/* CALL THE FUNCTION HERE */ 

if(Resize_Image($save,$file,$t_w,$t_h,$s_path,$o_path)) {  

//Notice that the '$' sign was removed

}

However the problem error messages persist:
