HTML代码

下面是functions.php文件中短代码的php代码

functions upload ()

$file = $_FILES['file'];
$name = $file['name'];
$path = "/uploads/" . basename($name);
if (move_uploaded_file($file['tmp_name'], $path)) {

尝试使用此功能。在function.php

中定义此功能

<?php
function upload_user_file( $file = array() ) {

    require_once( ABSPATH . 'wp-admin/includes/admin.php' );

      $file_return = wp_handle_upload( $file, array('test_form' => false ) );

      if( isset( $file_return['error'] ) || isset( $file_return['upload_error_handler'] ) ) {
          return false;
      } else {

          $filename = $file_return['file'];

          $attachment = array(
              'post_mime_type' => $file_return['type'],
              'post_title' => preg_replace( '/\.[^.]+$/', '', basename( $filename ) ),
              'post_content' => '',
              'post_status' => 'inherit',
              'guid' => $file_return['url']
          );

          $attachment_id = wp_insert_attachment( $attachment, $file_return['url'] );

          require_once(ABSPATH . 'wp-admin/includes/image.php');
          $attachment_data = wp_generate_attachment_metadata( $attachment_id, $filename );
          wp_update_attachment_metadata( $attachment_id, $attachment_data );

          if( 0 < intval( $attachment_id ) ) {
            return $attachment_id;
          }
      }

      return false;
}
?>

并像这样使用

    <?php
    if(isset($_POST['upload']))
    {
       if( ! empty( $_FILES ) ) 
       {
          $file=$_FILES['file'];
          $attachment_id = upload_user_file( $file );

       }
    }
    ?>

<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" name="upload">
</form>

如果您想在自定义文件夹中上传，可以使用此功能

在functions.php

中添加该功能

function upload_user_file( $file = array(),$path ) {
    if(!empty($file)) 
    {


        $upload_dir=$path;
        $uploaded=move_uploaded_file($file['tmp_name'], $upload_dir.$file['name']);
        if($uploaded) 
        {
            echo "uploaded successfully ";

        }else
        {
            echo "some error in upload " ;print_r($file['error']);  
        }
    }

}

在您的template file中制作表格

<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file">
    <input type="submit" name="upload">
</form>

在get_header();功能

之前调用模板文件中的上传功能

if(isset($_POST['upload']))
    {

       if( ! empty( $_FILES ) ) 
       {
          $file=$_FILES['file'];   // file array
          $upload_dir=wp_upload_dir();
          $path=$upload_dir['basedir'].'/myuploads/';  //upload dir.
          if(!is_dir($path)) { mkdir($path); }
          $attachment_id = upload_user_file( $file ,$path);

       }
    }

使用wordpress中的表单上传文件
