POST-ing images with descriptions

[docyoung]

This is what I am trying to accomplish.  I have a site that users can upload images to and they go into a "to be checked" directory.  In my website admin panel, the contents of this directory are gathered and the images are displayed for either acceptance or rejection.  I am able to get this part coded.  However, I would also like a way for me to add descriptions to the photos on this same page.  However, I can't seem to figure out how to associate a specific text field for each of these images so that after the form is POSTed I can recall which description went with what image.  Here is part of the code:

 

manage_photos.php

<?php
	include "PhotoManager.php";
	$photo_manager = new PhotoManager();
	$photo_process_dir = "uploads/photos/";
	$accepted_photos_dir = "../photos/";
	$rejected_photos_dir = "uploads/photos/rejected/";

	// are we processing photos or just viewing the list?
	if (isset($_POST["accept"]))
	{
		foreach($_POST["decision"] as $var)
		{
			**** THIS IS WHERE I NEED TO FIGURE OUT HOW TO GET THE DESC ****
			$photo_manager->addPhoto($var, $desc);
		}
	}
	else if (isset($_POST["reject"]))
	{
		foreach($_POST["decision"] as $var)
		{
			$photo_manager->rejfectPhoto($var);
		}
	}

	$photo_dir_handle = opendir($photo_process_dir);

	while ($current_file = readdir($photo_dir_handle))
		$file_list[] = $current_file;

	closedir($photo_dir_handle);

	sort($file_list);

	echo "<form id=\"decisionForm\" action=\"manage_photos.php\" method=\"POST\">\n";
	echo "<table border=1 cellpadding=1 cellspacing=1>\n";
	echo "<tr><th>Filename</th><th>Thumbnail</th><th>Decision?</th><th>Description</th></tr>\n";

	foreach ($file_list as $photo)
	{
		echo "<tr>\n";
		echo "<td>" . $photo . "</td>\n";
		echo "<td><img src=\"" . $photo_process_dir . $photo . "\" width=" . $thumb_width . " height=" . $thumb_height . "></img></td>\n";
		echo "<td><input type=\"checkbox\" name=\"decision[]\" value=\"" . $photo_process_dir . $photo . "\"></td>\n";
		echo "<td><input type=\"text\" name=\"desc[]\" value=\"\"></td>\n";
		echo "</tr>\n";
	}

	echo "</table>\n";
	echo "<br />";
	echo "<input type=\"submit\" name=\"accept\" value=\"Accept Checked\">\n";
	echo "<input type=\"submit\" name=\"reject\" value=\"Reject Checked\">\n";
	echo "</form>\n";
?>

 

The way it's set up, each row of the table has a checkbox at the end.  Depending on which submit button is clicked, all the selected images are either accepted or rejected.  Again, that all works fine. I just don't know how to get anything typed in the "desc[]" text boxes to associate with its given image.  I tried naming the text boxes based on the image, such as:

 

<input type=\"text\" name=\" . $photo_process_dir . $photo . "\" value=\"\">

 

Since whatever check boxes are selected will carry their value into the $_POST["decision"] array, I thought I could match up that value to the name of the textbox, but I've had no success.

would you want to use a database to store this information or would it be another method, such as a text file, with a name based on the image, and you write the description into the text file?

 

both processes would do the job and wouldn't be too hard to do. I would say with the arrays it should correspond that the keys for both descision and description would match so loop through one array using key and value should do it

$desc = $_POST['desc'];
foreach($_POST["decision"] as $key =>$var)
		{
			**** THIS IS WHERE I NEED TO FIGURE OUT HOW TO GET THE DESC ****
                                $photo_manager->addPhoto($var, $desc[$key]);
		}

 

I am not sure if the code is quite correct, as I have never tried it but I am sure it would work like this, since both arrays should have the corresponding keys matching the image to the description
