dynamic buttons

dmhicken

Hi,

I am trying to build a form that will list a directory of files and place either an "add" or "delete" button next to each file. If the button is selected the file name will be used in a php function that will allow me to place or delete this file name in a database. The list of files can reach 150.

I am lost, can anyone help with this?

Here you go, I just wrote a little something up for you. Let me know how it works...

<?PHP

if(isset($file)) {
if($HTTP_POST_VARS['add']) {
echo "Here I will add " . $file . "\n";
} elseif($HTTP_POST_VARS['delete']) {
echo "Here I will delete " . $file . "\n";
} else {
echo "An error has occurred\n";
}
} else {
$directory = '/home/mjw21/www';
if ($dh = @opendir($directory)) {
while (($file = readdir($dh)) !== false) {
if(is_file($file)) {
echo "<FORM action=\"$PHP_SELF?file=".$file."\" method=\"POST\">\n";
echo $file . " \n";
echo "<input type=\"submit\" class=\"button\" name=\"add\" value=\"Add\">\n";
echo "<input type=\"submit\" class=\"button\" name=\"delete\" value=\"Delete\">\n";
echo "</FORM>\n";
}
}

closedir($dh);
}
}

Thank you, that does work. I had some problems at first because the isfile test fails. Is that because of the . and .. files in the directory?

When I implement this code, it works the first time it is executed but I am having trouble redisplaying the list of files. When it reloads the page it has the ?file=filename attached to the URL and I cannot for the life of me figure out how to get rid of it. Any help would be useful.

Thanks again

} elseif($HTTP_POST_VARS['delete']) {
echo "Here I will delete " . $file . "\n";
} else {
echo "An error has occurred\n";
}
echo "<br><a href=\"".$PHP_SELF."\">Back</a>\n";
} else {
$directory = '/home/mjw21/www';
if ($dh = @opendir($directory)) {
while (($file = readdir($dh)) !== false) {
if(is_file($file)) {
echo "<FORM action=\"$PHP_SELF?file=".$file."\" method=\"POST\">\n";
echo $file . " \n";
echo "<input type=\"submit\" class=\"button\" name=\"add\" value=\"Add\">\n";
echo "<input type=\"submit\" class=\"button\" name=\"delete\" value=\"Delete\">\n";
echo "</FORM>\n";
}
}

closedir($dh);
}
}

That will add a back link to the page after you click the add or delete. Click the back link and you will be back to the list of files....
