I am using slim image cropper.
I have the following.
<div class="slim" data-service="async.php" data-ratio="3:2" data-size="600,400" data-row="">
<!-- <input type="hidden" id="rowID" name="rowID"> -->
<input type="file"/>
</div>
I added the data-row=" " and then in the jquery I added the following.
$('.slim').attr('data-row', rowID);
That part is working fine, but now how do I retireve the value of the data-row on the async.php page?
Here is ASYNC.php
<?php
// Uncomment if you want to allow posts from other domains
// header('Access-Control-Allow-Origin: *');
require_once('slim.php');
foreach(Slim::getImages() as $imagess) {
echo $imagess['meta']->data-row;
}
// Get posted data, if something is wrong, exit
try {
$images = Slim::getImages();
}
catch (Exception $e) {
// Possible solutions
// ----------
// Make sure you're running PHP version 5.6 or higher
Slim::outputJSON(array(
'status' => SlimStatus::FAILURE,
'message' => 'Unknown'
));
return;
}
// No image found under the supplied input name
if ($images === false) {
// Possible solutions
// ----------
// Make sure the name of the file input is "slim[]" or you have passed your custom
// name to the getImages method above like this -> Slim::getImages("myFieldName")
Slim::outputJSON(array(
'status' => SlimStatus::FAILURE,
'message' => 'No data posted'
));
return;
}
// Should always be one image (when posting async), so we'll use the first on in the array (if available)
$image = array_shift($images);
// Something was posted but no images were found
if (!isset($image)) {
// Possible solutions
// ----------
// Make sure you're running PHP version 5.6 or higher
Slim::outputJSON(array(
'status' => SlimStatus::FAILURE,
'message' => 'No images found'
));
return;
}
// If image found but no output or input data present
if (!isset($image['output']['data']) && !isset($image['input']['data'])) {
// Possible solutions
// ----------
// If you've set the data-post attribute make sure it contains the "output" value -> data-post="actions,output"
// If you want to use the input data and have set the data-post attribute to include "input", replace the 'output' String above with 'input'
Slim::outputJSON(array(
'status' => SlimStatus::FAILURE,
'message' => 'No image data'
));
return;
}
// if we've received output data save as file
if (isset($image['output']['data'])) {
// get the name of the file
$name = $image['output']['name'];
// get the crop data for the output image
$data = $image['output']['data'];
// If you want to store the file in another directory pass the directory name as the third parameter.
// $output = Slim::saveFile($data, $name, 'my-directory/');
// If you want to prevent Slim from adding a unique id to the file name add false as the fourth parameter.
// $output = Slim::saveFile($data, $name, 'tmp/', false);
// Default call for saving the output data
$output = Slim::saveFile($data, $name, 'images/modules/listings');
}
// if we've received input data (do the same as above but for input data)
if (isset($image['input']['data'])) {
// get the name of the file
$name = $image['input']['name'];
// get the crop data for the output image
$data = $image['input']['data'];
// If you want to store the file in another directory pass the directory name as the third parameter.

// $input = Slim::saveFile($data, $name, 'tmp/', false);
// Default call for saving the input data
$input = Slim::saveFile($data, $name, 'images/modules/listings');
}
//

That is all the pages includes, I am not sure where to even add this so I can retrieve this rowID, is it under the async, or the slim. Sorry for the confusion. Hopefully adding these pages helped clear some stuff up.
