从带有图像的表单创建帖子

时间：2011-07-12 作者：DennisT

我在Wordpress Answers网站上发现了这个由@Bainternet创建的奇妙脚本，它可以将图像从html表单附加到帖子中。。

我试图将in合并到我的“要发布的html表单”脚本中。。我确实在后端创建了一个post as draft。。但图像不会显示，也不会显示在“媒体”中。。

这是@Bainternet脚本/答案，Submit post and upload image from front-end

这是我的，

<?php 


if(isset($_POST[\'new_post\']) == \'1\') {
$post_title = $_POST[\'post_title\'];
$post_category = \'fashion\';
$post_content = $_POST[\'post_content\'];

$new_post = array(
      \'ID\' => \'\',
      \'post_author\' => $user->ID, 
      \'post_category\' => array($post_category),
      \'post_content\' => $post_content,
      \'post_title\' => $post_title,
      \'post_status\' => \'draft\'
    );

$post_id = wp_insert_post($new_post);


        if (!function_exists(\'wp_generate_attachment_metadata\')){
            require_once(ABSPATH . "wp-admin" . \'/includes/image.php\');
            require_once(ABSPATH . "wp-admin" . \'/includes/file.php\');
            require_once(ABSPATH . "wp-admin" . \'/includes/media.php\');
        }
         if ($_FILES) {
            foreach ($_FILES as $file => $array) {
                if ($_FILES[$file][\'error\'] !== UPLOAD_ERR_OK) {
                    return "upload error : " . $_FILES[$file][\'error\'];
                }
                $attach_id = media_handle_upload( $file, $post_id );
            }   
        }
        if ($attach_id > 0){
            //and if you want to set that image as Post  then use:
            update_post_meta($post_id,\'_thumbnail_id\',$attach_id);
        }


// This will redirect you to the newly created post
$post = get_post($post_id);
wp_redirect( \'http://domain.com\' );
}      
?>      

<form method="post" action=""> 
<input type="text" name="post_title" size="45" id="input-title" value="heading"/><br>

我想问题是你的表单标签丢失了enctype="multipart/form-data" 因此，请尝试更改：

<form method="post" action="">

收件人：

<form method="post" action="" enctype="multipart/form-data">

另外，如果要重定向到新创建的post更改，请执行以下操作：

wp_redirect( \'http://domain.com\' );

收件人：

wp_redirect( get_permalink($post_id));
exit();

更新：从评论中我了解到，我希望图像显示在内容中，这是另一回事，但不是那么难，

更改：

if ($attach_id > 0){
            //and if you want to set that image as Post  then use:
            update_post_meta($post_id,\'_thumbnail_id\',$attach_id);
        }

收件人：

if ($attach_id > 0){
    $post = get_post($post_id,\'ARRAY_A\');
    $image = wp_get_attachment_image_src( $attach_id );
    $image_tag = \'<img src="\'.$image[0].\'" width="\'.$image[1].\'" height="\'.$image[2].\'" />\';

    //add image above the content
    $post[\'post_content\'] = $image_tag . $post[\'post_content\'];

    //add image under the content
    //$post[\'post_content\'] = $post[\'post_content\'] . $image_tag;

    $post_id =  wp_update_post( $post );
}

对于每个需要相同脚本的人。

它的作用是，一个简单的html表单将图像和一些文本上传到wordpress和media gallery，并根据发布的内容创建一篇文章作为草稿。并将您重定向到创建的帖子进行预览。

非常感谢@Bainternet

我已经尝试过这个代码，当我尝试时，什么都没有发生。我还没有使用这个图片，我只是想用这个表格来写一篇新文章。但表单变量似乎是空的。

我使用var\\u转储进行检查，但我的表单中没有任何内容。在最新版本的wordpress中，上述代码对我不起作用。我不得不把它改成这个

$my_post = array();
    $my_post[\'post_title\'] = "My Post"
    $my_post[\'post_content\']  = \'This is my post.\';
    $my_post[\'post_status\']   = \'publish\';
    $my_post[\'post_author\']   = 1;
    $my_post[\'post_category\'] = array(9);

这就是我做测试的方式，它确实是这样工作的，只有帖子类别不能与slug一起工作，这可能是一个问题。每当我尝试用$\\u post[\'name\']替换post\\u title时，代码都会失败。这是我的表格

<form action=" " method="post" name="reservations" id="reservations" enctype="multipart/form-data"> 

    <table width="474" border="0" cellspacing="0" cellpadding="0" id="reserve">
        <tr>
                            <td class="formInput"><input type="text" id="name" name="name" /></td>

结束
