Question

Well.. I have been looking for a image upload with a crop and resize function..

Found a lot.
But I can find one where I can choose a MUST-BE width..

So that if my MUST-BE width is set to be 250px.

Then the crop should allow a minumum width, which should be the set MUST-BE width.
It should be possible to be bigger then the MUST-BE width while cropping, but after cropping, it should resize the width to be the set MUST-BE width..

Hope I make sense.

I found this: http://www.nwhite.net/2009/02/25/lassocrop-preview/
Which do most of the magic.

I just don’t know how to get PHP to do those actions after selected the right crop size?
And how to make the upload function to work with this.

Answer 1

here we can get x,y ,h and w. Then you can assign these values to four different hidden input fields for eg:

        <input type="hidden" name="x1" value="" id="x1" />
        <input type="hidden" name="y1" value="" id="y1" />
        <input type="hidden" name="x2" value="" id="x2" />
        <input type="hidden" name="y2" value="" id="y2" />
        <input type="hidden" name="w" value="" id="w" />
        <input type="hidden" name="h" value="" id="h" /> 

like that and using form action you can get all values at action page \

$x1 = $_POST["x1"];
$y1 = $_POST["y1"];
$x2 = $_POST["x2"];
$y2 = $_POST["y2"];
$w  = $_POST["w"];
$h  = $_POST["h"]; 

Using some php image functions we can crop images

imagecreatetruecolor();

imagecopyresampled();

imagegif() or imagejpeg() or imagepng ()

I think these can already know these basic php functions and how to use it Thanks
