I have 2 scripts that I have managed to et working independently, and now need to combine them.
The first script is an image uploader - which uploads images, stores the original plus a resized image plus a thumbnail.
The second script reads the Exif data of an image and displays it. The image name that is read is hard coded in the script.
What I would like is to have the second script load automatically on completion of the upload and read the information from the uploaded image.
I have no experience of coding and although I can find my way around the simle scips I ave no idea where to start with the combining of these two.
If anyone can point me in the right direction it would be much appreciated.
The first script is i two parts, the html page and the php script called.
The html content:
<?php require_once("maxImageUpload.class.php"); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>
<body>
<?php
$myImageUpload = new maxImageUpload();
//$myUpload->setUploadLocation(getcwd().DIRECTORY_SEPARATOR);
$myImageUpload->uploadImage();
?>

And here is the first few lines of the third file:
<?
// +++++++++++++++++++++++++ //
// +++++++ EXTRACT EXIF +++++++ //
// +++++++++++++++++++++++++ //
// --- Change the 'image.jpg' value below to call the file required file. --- //
$Image = 'image.jpg';
// --- Read EXIF Data --- //
$exif = exif_read_data($Image, 0, true);
// --- The EXIF GPS Conversion Degrees to Decimal --- //
function toDecimal($deg, $min, $sec, $hemi) {
$d = $deg + $min/60 + $sec/3600;
return ($hemi=='S' || $hemi=='W') ? $d*=-1 : $d;
In the third file, when it loads after completion of the upload I need it to call the original image and read the exif data from that.
Sorry for the lengthy post, but hopefully someone will be able to analyse it and advise me on how to move forward.
Thanks.
