Question

我跟进sitepoint tutorial为我的选项页面创建徽标上传器，但图片上传器无法正常工作。

这里是 functions.php ：

class Image(models.Model):
    name = models.CharField(max_length=300)
    path = models.CharField(max_length=300)

class User(models.Model):
    name = models.CharField(max_length=300)
    id = models.IntegerField()
    images = models.ManyToManyField(Image)

Answer 1

如果您查看来源，您将会看到enctype未设置为enctype =＆＃34; multipart / form-data＆＃34;。您可以执行以下操作来更改enctype

function change_form_enc() {
        echo "<script type='text/javascript'>
                  jQuery(document).ready(function(){
                      jQuery('form').attr('enctype','multipart/form-data');
                  });
              </script>";
}



if ( is_admin() ) {

    add_action('admin_head', 'change_form_enc');
}

function logo_display()
{
    ?>
        <input type="file" id="logo" name="logo" /> 
        <?php echo get_option('logo'); ?>
   <?php
}

function handle_logo_upload()
{
    if(!empty($_FILES["logo"]["tmp_name"]))
    {
        $urls = wp_handle_upload($_FILES["logo"], array('test_form' => FALSE));
        if ($urls["error"]) 
        {
            return $urls["error"];
        }
        $temp = $urls["url"];
        return $temp;   
    } 
    return get_option('logo');
}

wordpress上传徽标不起作用
