Add description to photo upload form
I need help getting description field ( called "caption" in my form) added to the form to be saved in action. This is for Tidypics plugin. By default you upload image first and then go add titles/descriptions to photos.
I have new form and action files (edited originals) that work fine in uploading photo but the description/caption field is not getting saved. I have an idea which part could be the problem and needs bit of editing to make it work, maybe someone with good "Elgg eye" can spot the problem and offer suggestion.
Here is the form code:
<?php
/**
* Basic uploader form
*
* This only handled uploading the images. Editing the titles and descriptions
* are handled with the edit forms.
*
* @uses $vars['entity']
*
* @author Cash Costello
* @license http://www.gnu.org/licenses/gpl-2.0.html GNU General Public License v2
*/
$album = $vars['entity'];
$access_id = $album->access_id;
$maxfilesize = (float) elgg_get_plugin_setting('maxfilesize', 'tidypics');
$instructions = elgg_echo("tidypics:uploader:upload");
$max = elgg_echo('tidypics:uploader:basic', array($maxfilesize));
//$title = elgg_extract('title', $vars, '');//THIS IS MY DESCRIPTION/CAPTION
$captions = elgg_extract('caption', $vars, '');
$list = '';
for ($x = 0; $x < 10; $x++) {
$list .= . elgg_view('input/file', array('name' => 'images[]')) . '<div><label>' . elgg_echo('caption') . '</label>' . elgg_view('input/longtext', array('name' => 'caption', 'value' => $captions,)) . '</div></div>';
}
$foot = elgg_view('input/hidden', array('name' => 'guid', 'value' => $album->getGUID()));
$foot .= elgg_view('input/submit', array('value' => elgg_echo("Upload")));
$form_body = <<<HTML
<div>
$list
</div>
<div class='elgg-foot'>
$foot
</div>
HTML;
echo elgg_view('input/form', array(
'body' => $form_body,
'action' => 'action/photos/image/upload',
'enctype' => 'multipart/form-data',
));
?>
Here is the action code ( I think problem is that save($data) is wrapped in foreach ($_FILES['images']['name'] so it only saves image url/file):
elgg_load_library('tidypics:upload');
$img_river_view = elgg_get_plugin_setting('img_river_view', 'tidypics');
$titles = get_input('title');//THIS IS THE DESCRIPTION/CAPTION INPUT FROM THE FORM
$captions = get_input('caption');
// test to make sure at least 1 image was selected by user
$num_images = 0;
foreach($_FILES['images']['name'] as $name) {
if (!empty($name)) {
$num_images++;
}
}
if ($num_images == 0) {
// have user try again
register_error(elgg_echo('tidypics:noimages'));
forward(REFERER);
}
// create the image object for each upload
$uploaded_images = array();
$not_uploaded = array();
$error_msgs = array();//THIS I THINK IS THE PROBLEM AS BELOW SAYS $result = $image->save($data);
foreach ($_FILES['images']['name'] as $index => $value) {
$data = array();
foreach ($_FILES['images'] as $key => $values) {
$data[$key] = $values[$index];
}
if (empty($data['name'])) {
continue;
}
//HERE I'M TRYING TO ADD CAPTION FIELD DATA TO BE ADDED TO $data
$captions = get_input('caption');
foreach ($_FILES['caption']['name'] as $keys => $caption) {
$capt[$keys] = $captions[$index];
}
$mime = tp_upload_get_mimetype($data['name']);
$image = new TidypicsImage();
$image->container_guid = $album->getGUID();

$image->access_id = $album->access_id;

try {

}
register_error($error);
if (count($uploaded_images) == 0) {
//upload failed, so forward to previous page

// some images did upload so we fall through
}
} else {
system_message(elgg_echo('tidypics:upl_success'));

Please give me suggestions, anything :)
Thanks.
