Web app some advice required easy!!!

Hello all

Wonder if anyone could give me some pointers here.

What I need is something really quick and dirty to do the following.

On a server machine, with a webserver installed, display a web page containing upto ~ 250 images in a column, beside each image is a tick box.

At the bottom is a submit button.

The idea is the user scrolls down (these are scanned forms, i.e every 8 or 16 or 12 or 24 images, the next form starts) anyway the user scrolls down, clicks the tick box beside each image of a front page, then clicks submit.

The it moves to the next directory and displays the next set of images.

The output of this should be a file that contains the full path to each image that was tick boxed.

I have scripts that take this file and process the images as required.

More wondering about quickly I can prototype the above idea using PHP/RUBY/ etc??? Any help here?

Currently the method employed is to use iorfanview, and the customiable external editor comman. Page through the images and hit SHIFT+E on the front page. This runs the external editor *(actually a batch script that just echoes the file name into an imglist.txt file.

Problems with this approach involve lots of client side setup. and General 'hackiness' of the solution and a bit of training for each user. If I could get a web page thing ther could be nothing easier than clickign the required tick box and hittign submit.

Regards.

Thanks for any input.

OK I am attempting to get this done, PHP looks quite good for this, I downloaded and installed WAMP and coded this :

PHP:

<html> 
<head></head>
<body>

<?php


//define the path as relative
$path = "C:\test\gifs";
$fileNames = array();
//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

echo "Directory Listing of $path</br>";

//running the while loop
while ($file = readdir($dir_handle)) 
{
   if($file!="." && $file!="..")
      echo "<a href='$file'>$file</a><br/>";
	  array_push($fileNames, $file);
}


//closing the directory
closedir($dir_handle);

echo "TEST READ BACK";
foreach ($fileNames as $a) { 
echo "<img src='$path\\$a' alt='$a'><br />";
}
?>
</body>
</html>

Now the question is how to get the images displaying from a location on the filesystem not in c:\wamp\www ? If I run the above the images don't display, but if i copy the image address from the image properties and then paste in my address bar it works.

I know it's a local address - but this shouldn't make any difference?

cheers

Hi . got the above solved with apache aliasing.

I'm looking for the way to read the array from a form with check boxes.

This code displays images (~300 128x128 thumbs) with their name and a check box beside each one. I want to when the user clicks submit echo back the filenames of whichever images had check boxes beside them.

heres the code:
index.php

PHP:

<html> 
<head></head>
<body>

<?php


//define the path as relative
$path = "/test/gifs";
$fileNames = array();
//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

echo "Directory Listing of $path</br>";

//running the while loop
while ($file = readdir($dir_handle)) 
{
   if($file!="." && $file!="..")
     // echo "<a href='$file'>$file</a><br/>";
	  array_push($fileNames, $file);
}
$jobName = testjob;
$batchNo = 0524;
$operatorName = user;
$columnCount = 8 ;

//closing the directory
closedir($dir_handle);

// call function 
toppanel($jobName, $batchNo, $operatorName); 

?>
<STYLE TYPE="text/css">
<!--
TD{font-family: Arial; font-size: 10pt;}
--->
</STYLE>
<form action="index7.php" method="post"> 
<?php
// echo "TEST READ BACK<br>";
$colCount = 0 ;
$rowCount = 0 ;	

?>
<div align="center"><table border="1" id="table1" bgcolor="#AA99ED" cellspacing="1" bordercolorlight="#FFFFFF" bordercolordark="#808080"><tr>
<?php
foreach ($fileNames as $a) { 
	// echo "<img src='$path\\$a' alt='$a'border=10>";
?>
		<td><img src='<?php echo "$path\\$a" ; ?>' alt='<?php $a; ?>'border=2><BR>&nbsp;<input type="checkbox" name="<?php echo "$path\\$a" ; ?>" value="true">&nbsp;<?php echo $a; ?><P></td>
<?php
	$colCount = $colCount + 1 ;
	if ($colCount == $columnCount) { 
		echo  "</tr>" ;
		$colCount = 0 ;
	}
}
?>
</table>

</div>

Comments: <input type="text" name="comment" size="50"> 
<input type="submit" value="Send">
</body>
<?php
// define a function 
function toppanel($jobName, $batchNo, $operatorName) { 
?>
<div align="center">
	<table border="1" width="75%" id="table2">
		<tr>
			<td><b>Jobname: <?php echo $jobName; ?></b></td>
			<td><b>Batch: <?php echo $batchNo; ?></b></td>
			<td><b>Operator: <?php echo $operatorName; ?></b></td>
		</tr>
	</table>
	<P>
</div>
<?php
} 
echo "</html>";
?>

index7.php

PHP:

<html> 
<head></head>
<body>

<?php
//define the path as relative
$path = "/test/gifs";
$fileNames = array();
//using the opendir function
$dir_handle = @opendir($path) or die("Unable to open $path");

echo "Directory Listing of $path</br>";

//running the while loop
while ($file = readdir($dir_handle)) 
{
   if($file!="." && $file!="..")
     // echo "<a href='$file'>$file</a><br/>";
	  array_push($fileNames, $file);
}

// get form selection
$comment = $_POST['comment'];
// check value and select appropriate item
echo $comment;
foreach ($fileNames as $a) { 
//	echo $a;
	echo $_POST['$a'];
}

?>

</body>
</html>
