myimages请建议我，我如何获取图像名称。
try这个
$directory = "mytheme/images/myimages";
$images = glob($directory . "/*.jpg");
foreach($images as $image)
{
echo $image;
}
您可以简单地使用php
示例：
$handle = opendir(dirname(realpath(__FILE__)).'/pictures/');
while($file = readdir($handle)){
if($file !== '.' && $file !== '..'){
echo '<img src="pictures/'.$file.'" border="0" />';
}
}
当您想从文件夹中获取所有图像，然后使用内置函数内置的功能，从而有助于获取所有图像。但是，当您获得全部时，有时需要检查所有内容是否有效，因此在这种情况下，此代码会为您提供帮助。此代码还将检查它是图像
glob()
如果您不想检查图像类型，那么您也可以使用此代码
$all_files = glob("mytheme/images/myimages/*.*");
for ($i=0; $i<count($all_files); $i++)
{
$image_name = $all_files[$i];
$supported_format = array('gif','jpg','jpeg','png');
$ext = strtolower(pathinfo($image_name, PATHINFO_EXTENSION));
if (in_array($ext, $supported_format))
{
echo '<img src="'.$image_name .'" alt="'.$image_name.'" />'."<br /><br />";
} else {
continue;
}
}
PHP手册
这里是我的一些代码
$all_files = glob("mytheme/images/myimages/*.*");
for ($i=0; $i<count($all_files); $i++)
{
$image_name = $all_files[$i];
echo '<img src="'.$image_name .'" alt="'.$image_name.'" />'."<br /><br />";
}
th这个答案是wordpress的特定于特定的：
$dir = '/Images';
$ImagesA = Get_ImagesToFolder($dir);
print_r($ImagesA);
function Get_ImagesToFolder($dir){
$ImagesArray = [];
$file_display = [ 'jpg', 'jpeg', 'png', 'gif' ];
if (file_exists($dir) == false) {
return ["Directory \'', $dir, '\' not found!"];
}
else {
$dir_contents = scandir($dir);
foreach ($dir_contents as $file) {
$file_type = pathinfo($file, PATHINFO_EXTENSION);
if (in_array($file_type, $file_display) == true) {
$ImagesArray[] = $file;
}
}
return $ImagesArray;
}
}
在这里还有其他一些设置，它将为您提供其他地方的图像。只需将上述代码中的前2行替换为您需要的版本：
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );
$media_dir = $base_dir . 'yourfolder/images/';
$media_url = $hase_url . 'yourfolder/images/';
$image_paths = glob( $media_dir . '*.jpg' );
$image_names = array();
$image_urls = array();
foreach ( $image_paths as $image ) {
$image_names[] = str_replace( $media_dir, '', $image );
$image_urls[] = str_replace( $media_dir, $media_url, $image );
}
// --- You now have:
// $image_paths ... list of absolute file paths
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
// $image_urls ... list of absolute file URLs
// e.g. http://example.com/wp-content/uploads/yourfolder/images/sample.jpg
// $image_names ... list of filenames only
// e.g. sample.jpg
// e.g. /path/to/wordpress/wp-content/uploads/yourfolder/images/sample.jpg
$upload_path = wp_upload_dir();
$base_dir = trailingslashit( $upload_path['basedir'] );
$base_url = trailingslashit( $upload_path['baseurl'] );
// e.g. /path/to/wordpress/wp-content/themes/parent-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_template_directory() );
$base_url = trailingslashit( get_template_directory_uri() );
// e.g. /path/to/wordpress/wp-content/themes/child-theme/yourfolder/images/sample.jpg
$base_dir = trailingslashit( get_stylesheet_directory() );
$base_url = trailingslashit( get_stylesheet_directory_uri() );
非常快，因为您只扫描所需的目录。
$dir = "mytheme/images/myimages";
$dh = opendir($dir);
while (false !== ($filename = readdir($dh))) {
$files[] = $filename;
}
$images=preg_grep ('/\.jpg$/i', $files);
检查是否存在，将所有文件放入数组中，Preg grep grep所有JPG文件，回声呼应所有图像的新数组可以尝试以下操作：
//path to the directory to search/scan
$directory = "";
//echo "$directory"
//get all files in a directory. If any specific extension needed just have to put the .extension
//$local = glob($directory . "*");
$local = glob("" . $directory . "{*.jpg,*.gif,*.png}", GLOB_BRACE);
//print each file name
echo "<ul>";
foreach($local as $item)
{
echo '<li><a href="'.$item.'">'.$item.'</a></li>';
}
echo "</ul>";
$images=preg_grep('/\.(jpg|jpeg|png|gif)(?:[\?\#].*)?$/i', $files);
if ($handle = opendir('/path/to/folder')) {
while (false !== ($entry = readdir($handle))) {
$files[] = $entry;
}
$images=preg_grep('/\.jpg$/i', $files);
foreach($images as $image)
{
echo $image;
}
closedir($handle);
}
uikit php文件夹库
<?php
$galleryDir = 'gallery/';
foreach(glob("$galleryDir{*.jpg,*.gif,*.png,*.tif,*.jpeg}", GLOB_BRACE) as $photo)
{echo "<a href=\"$photo\">\n" ;echo "<img style=\"padding:7px\" class=\"uk-card uk-card-default uk-card-hover uk-card-body\" src=\"$photo\">"; echo "</a>";}?>
// Store your file destination to a variable
$fileDirectory = "folder1/folder2/../imagefolder/";
// glob function will create a array of all provided file type form the specified directory
$imagesFiles = glob($fileDirectory."*.{jpg,jpeg,png,gif,svg,bmp,webp}",GLOB_BRACE);
// Use your favorite loop to display
foreach($imagesFiles as $image) {
echo '<img src="'.$image.'" /><br />';
}
thanks对于一个不错的问题，只需确保您的服务器权限允许访问文件夹即可。我的WordPress网站还可以管理图像，因此，如果您想看看堪萨斯州的Brass Armadillo Antique Mall，您可以看到图像的井井有条，希望这会再次感谢您
您可以简单地显示您的实际图像目录（较不安全）。仅2行代码。
get all the images from a folder in php without database
$url='https://demo.com/Images/sliderimages/';
$dir = "Images/sliderimages/";
$file_display = array(
'jpg',
'jpeg',
'png',
'gif'
);
$data=array();
if (file_exists($dir) == false) {
$rss[]=array('imagePathName' =>"Directory '$dir' not found!");
$msg=array('error'=>1,'images'=>$rss);
echo json_encode($msg);
} else {
$dir_contents = scandir($dir);
foreach ($dir_contents as $file) {
@$file_type = strtolower(end(explode('.', $file)));
// $file_type1 = pathinfo($file);
// $file_type= $file_type1['extension'];
if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true) {
$data[]=array('imageName'=>$url.$file);
}
}
