deleting images by clicking correspondent buttons - php

Question

I have a folder / directory containing lots of images and other folders / directories.
I am showing the preview of these files using following code:
<?php
$images=array();
$dir_handler = opendir('test') or die("Unable to open path");
$i=0;
while($file = readdir($dir_handler))
{
if(is_dir($file))
continue;
else if($file != '.' && $file != '..' && $file != 'index.php')
{
$images[$i]=$file;
$i++;
}
}
sort($images);
for($i=0; $i<sizeof($images); $i++)
{
echo "<img style='border:1px solid #666666; width:100px;height:100px; margin: 10px;' src='test/".$images[$i]."'/><input type='button' value='nok[]'>";
} closedir($dir);
?>
The problem is that I want to assign a separate button to each file (to each image or folder), So that by clicking each button, its corresponding image (or folder / directory) gets deleted from the main folder and no more being shown as a preview.
Another small problem is that the preview of folders are not being shown with the above code. Why? Any help will be appreciated.

Answer 1

There are several questions here.
First question: Why won't preview of folders show? This is because you show previews by looping through the $images array, but you do not add directories to that array (see your code where you check if it is_dir and then invoke "continue;"). If you want to include the directories, then you should include them in the $images array (or do something else with them).
Second question: How to do the deleting? You need to either extend your existing PHP script or write another one. You would create a link on the delete icon; the link's href would be to the new (or existing) PHP script and you would pass in as parameters the folder or file to be deleted. If it is a folder, then use rmdir(). If it is a file, then use unlink(). I can help you more with this later, if you need it.

Answer 2

You are always displaying an image, you need to do a check if the $images array value is an image or a folder. Then do something different with the display.
To delete a file or folder, use these functions respectively:
unlink();
rmdir();
http://www.php.net/manual/en/function.rmdir.php
http://php.net/manual/en/function.unlink.php
To add a list of folders before your images change your code to:
<?php
$images=array();
$folders = array();
$dir_handler = opendir('test') or die("Unable to open path");
$i=0;
while($file = readdir($dir_handler))
{
if(is_dir($file)) {
$folders[count($folders)] = $file;
}
else if($file != '.' && $file != '..' && $file != 'index.php')
{
$images[$i]=$file;
$i++;
}
}
sort($images);
foreach($folders as $folder){
echo "<a href='#'>$folder</a>";
}
for($i=0; $i<sizeof($images); $i++)
{
echo "<img style='border:1px solid #666666; width:100px;height:100px; margin: 10px;' src='test/".$images[$i]."'/><input type='button' value='nok[]'>";
}
closedir($dir);
?>
Then all you have to do is build out the visual elements of a folder in your view and link to a function that will do your unlink() and rmdir() where needed.
