Insert Images from folder and subfolder php - php

Question

Im trying to insert into html all images that are on the folder "assets/imagens/" and on any subfolders. I also need help to validate not to echo the subfolders.
Im using the code below:
$path = "assets/imagens/";
$diretorio = dir($path);
while($arquivo = $diretorio -> read()){
if($arquivo != '.' && $arquivo != '..'){
echo '<div href="#" class="list-group-item">';
echo '<span class="close-button" secao="imagens">x</span>';
echo "<img class='max-width' src='".base_url().$path.$arquivo."' />";
echo '</div>';
}
}
$diretorio -> close();

Answer 1

$path = "assets/imagens/";
echo_directory_images($path);
function echo_directory_images($path)
{
$diretorio = dir($path);
while($arquivo = $diretorio -> read()){
if($arquivo != '.' && $arquivo != '..'){
if( is_dir($path.$arquivo))
{
//if subfolder
echo_directory_images($path.$arquivo.'/')
}
else{
echo '<div href="#" class="list-group-item">';
echo '<span class="close-button" secao="imagens">x</span>';
echo "<img class='max-width' src='".base_url().$path.$arquivo."' />";
echo '</div>';
}
}
}
}
You may want to give a try to this function. I doubt if this will work exactly but this will surely give an idea about how to recursively call folders and subfolders.

Try this :
function listDir( $path ) {
global $startDir;
$handle = opendir( $path );
while (false !== ($file = readdir($handle))) {
if( substr( $file, 0, 1 ) != '.' ) {
if( is_dir( $path.'/'.$file ) ) {
listDir( $path.'/'.$file );
}
else {
if( #getimagesize( $path.'/'.$file ) ) {
/*
// Uncomment if using with the below "pic.php" script to
// encode the filename and protect from direct linking.
$url = 'http://domain.tld/images/pic.php?pic='
.urlencode( str_rot13( substr( $path, strlen( $startDir )+1 ).'/'.$file ) );
*/
$url='http://localhost/'.$path.'/'.$file;
substr( $path, strlen( $startDir )+1 ).'/'.$file;
// You can customize the output to use img tag instead.
echo "<a href='".$url."'>".$url."</a><br>";
echo "<img class='max-width' src='".$url."' />";
}
}
}
}
closedir( $handle );
} // End listDir function
$startDir = "assets/imagens/";
listDir( $startDir );

You can use RecursiveDirectoryIterator.
For example:
$directory = new RecursiveDirectoryIterator('assets/imagens');
$iterator = new RecursiveIteratorIterator($directory);
foreach ($entities as $name => $entity) {
if ($entity->isDir()) {
continue;
}
$extension = pathinfo($name, PATHINFO_EXTENSION);
if ($extension == 'jpg' || $extension == 'png' || $extension == 'gif') {
echo '<img src="' . $entity->getPathname() . '" />';
}
}
