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">

<link href="style/style.css" rel="stylesheet" type="text/css" />
</head>
<body>
<?php
$myImageUpload = new maxImageUpload();
//$myUpload->setUploadLocation(getcwd().DIRECTORY_SEPARATOR);
$myImageUpload->uploadImage();
?>
</body>
Here is the file called (maxImageUpload.class.php)

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.
Restrictions on post length mean I have had to shorten the end of the middle script - so a copy is attached, and hopefully someone will be able to analyse it and advise me on how to move forward.
Thanks.
