PHP图像上传(WordPress自定义插件)（php图片上传插件）
我有一个正在使用的wordpress插件,似乎遇到了问题.
我需要用户能够上传图片,但我一直遇到这个问题：
上载目录不可写或不存在.
Warning:

该目录绝对存在,我什至将CHMOD更改为777进行测试.
products.PHP文件如下所示：
<?
if ('POST' == $_SERVER['REQUEST_METHOD'])
{
global $wpdb;
$product_title = $_POST['title'];
$product_url = $_POST['url'];
$product_btn_text = $_POST['btn_text'];
// CREATE UNIQUE NAME FOR IMAGE
$remote_addr = $_SERVER['REMOTE_ADDR'];
$time = time();
$new_name = $remote_addr;
$new_name .= $time;
// IMAGE UPLOAD
$upload_dir = "http://markpetherbridge.co.uk/ios/wp-content/plugins/rap/includes/productimages/";
if (file_exists($upload_dir) && is_writable($upload_dir)) {
echo "<br /> Directory exists and is fine.... <br />";
}
else {
echo "Upload directory is not writable, or does not exist. <br />";
}
$uploadedfile = $_FILES['image_file']['name'];
$extension = explode(".", $uploadedfile);
$extensiontype = $extension['1'];
$target_path = $upload_dir;
$target_path = $target_path .$new_name .'.'.$extensiontype;
if(move_uploaded_file($_FILES['image_file']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['image_file']['name']).
" has been uploaded <br />";
} else{
echo "There was an error uploading the file, please try again! <br />";
}
$product_img = $new_name.'.'.$extensiontype;
//ADD TO DATABASE
$wpdb->query("INSERT INTO wp_rec_amazon_product (product_title, product_url, product_img, product_btn_text) VALUES ('$product_title', '$product_url','$product_img','$product_btn_text')");
echo "You have successfully added " .$product_title. " to your products list";
} else { ?>
<form action="<?PHP $_SERVER['PHP_SELF']; ?>" method="POST" enctype="multipart/form-data">
<table border="0" bordercolor="none" width="50%" cellpadding="0" cellspacing="0">
<tr>
<td>Product Title:</td>
<td><input type="text" name="title" value="product title" /></td>
</tr>
<tr>
<td>Product Url</td>
<td><input type="text" name="url" value="product url" /></td>
</tr>
<tr>
<td>Button text</td>
<td><input type="text" name="btn_text" value="Get your copy" /></td>
</tr>
</table>
<input type="file" name="image_file" />
<input type="submit" value="Submit" />
</form>
<?PHP }?>
信息被添加到数据库中,只是图像上传似乎不起作用.
有人知道吗？谢谢大家.
php – WordPress tinyMCE自定义插件
我正在构建一个选项页面,我想控制传递给tinyMCE函数的变量,这样用户就可以选择要显示的按钮以及向编辑器添加自定义样式表.
在这一点上,我编辑微小的mce的功能很棒！选项页面还保存数据,复选框和我需要的其他所有内容.
我唯一的问题是我不了解如何将存储在“options.PHP”中的变量传递给当前的tinyMCE函数.这是我的functions.PHP文件中的当前函数：
function my_format_TinyMCE( $in ) {
//styles for the editor to provide better visual representation.
$in['content_css'] = get_template_directory_uri() . "/build/styles/tiny-mce-editor.css";
$in['block_formats'] = "Paragraph=p; heading 1=h1; heading 2=h2";
$in['toolbar1'] = 'formatselect,bold,italic,underline,superscript,bullist,numlist,alignleft,aligncenter,alignright,link,unlink,spellchecker';
$in['toolbar2'] = '';
$in['toolbar3'] = '';
$in['toolbar4'] = '';
return $in;
}
add_filter( 'tiny_mce_before_init','my_format_TinyMCE' );
我不想通过添加我的选项页面的所有代码来收集帖子,但是我可能需要一些关于如何处理传递变量作为$in []的值的方向.如前所述,变量将在选项页面中创建并保存,更新微小的mce函数.
我已经研究了很多,我找不到任何关于此的直接信息 – 像往常一样,我不是在寻找某人来做我的代码,但也许是为了让我朝着正确的方向前进.
谢谢！
编辑新代码
add_action('admin_menu','my_cool_plugin_create_menu');
function my_cool_plugin_create_menu() {
add_menu_page('My Cool Plugin Settings','Cool Settings','administrator',__FILE__,'my_cool_plugin_settings_page',plugins_url('/images/icon.png',__FILE__) );
add_action( 'admin_init','register_my_cool_plugin_settings' );
}
function register_my_cool_plugin_settings() {
//register our settings
register_setting( 'my-cool-plugin-settings-group','new_option_name' );
}
function my_cool_plugin_settings_page() {
?>
<div>
<h2>Your Plugin Name</h2>
<form method="post" action="options.PHP">
<?PHP settings_fields( 'my-cool-plugin-settings-group' ); ?>
<?PHP do_settings_sections( 'my-cool-plugin-settings-group' ); ?>
<table>
<tr valign="top">
<th scope="row">New Option Name</th>
<td><input type="text" name="new_option_name" value="<?PHP echo esc_attr( get_option('new_option_name') ); ?>" /></td>
</tr>
<?PHP submit_button(); ?>
</form>
</div>
<?PHP }
function my_format_TinyMCE( $in ) {
$toolbar = get_option('new_option_name');
//styles for the editor to provide better visual representation.
$in['content_css'] = get_template_directory_uri() . "/build/styles/tiny-mce-editor.css";
$in['block_formats'] = "Paragraph=p; heading 1=h1; heading 2=h2";
$in['toolbar1'] = $toolbar;
$in['toolbar2'] = '';
$in['toolbar3'] = '';
$in['toolbar4'] = '';
return $in;
}
add_filter( 'tiny_mce_before_init','my_format_TinyMCE' );
?>
我仍然无法访问存储的变量并在函数中使用它们.有任何想法吗？
解决方法
php – WordPress自定义小部件记住多个选择选项
我正在为我们的网站编写一个自定义小部件来显示一些选定的帖子.在管理部分,我有一个多选框,让管理员按名称选择多个帖子.这工作正常,但是当我选择几个不同的帖子并保存时,没有任何东西被保存.
任何人都可以对此有所了解吗？
这是我的代码……
<?PHP
/*
Plugin Name: Hot Topics
Plugin URI: http://www.weddingideasmag.com
Description: Use this widget to choose an array of posts snippets to show
Version: 1.0)
Author: James Payne
Author URI: http://www.bluntcreative.co.uk
License: GPL2
*/
class Hottopics extends WP_Widget {
// constructor
function Hottopics() {
$widget_ops = array( 'name' => 'Hot Topics','classname' => 'widget-hot-topics', 'description' => __( "Use this widget to choose an array of posts snippets to show in the sidebar." ) );
$this->WP_Widget( 'hottopics', __('Hot Topics'), $widget_ops);
}
// widget form creation
function form($instance) {
// Check values
if( $instance) {
$select = esc_attr($instance['select']); // Added
} else {
$select ='';
}
?>
<select multiple="multiple" name="<?PHP echo $this->get_field_name('select'); ?>[]" id="<?PHP echo $this->get_field_id('select'); ?>"size="15"https://www.jb51.cc/tag/ott/" target="_blank">ottom:15px;">
<?PHP
$args = array( 'offset'=> 1, 'orderby' => 'date', 'order' => 'DESC', 'posts_per_page' => 200, 'post_status' => 'publish' );
// The Query
query_posts( $args );
// The Loop
while ( have_posts() ) : the_post();
$title = get_the_title();
?>
<option value="<?PHP echo get_the_ID();?>"<?PHP $select == $title ? ' selected="selected"' : '';?>https://www.jb51.cc/tag/ott/" target="_blank">ottom:3px;">
<?PHP echo $title;?>
</option>
<?PHP
endwhile;
// Reset Query
wp_reset_query();
?>
</select>
<?PHP
}
// update widget
function update($new_instance, $old_instance) {
$instance = $old_instance;
// Fields
$instance['select'] = strip_tags($new_instance['select']);
return $instance;
}
// widget display
function widget($args, $instance) {
/* ... */
echo 'tetst';
}
}
// register widget
add_action('widgets_init', create_function('', 'return register_widget("Hottopics");'));
?>
解决方法:
更新窗口小部件时,strip_tags正在销毁所选帖子的数组. esc_sql完成这项工作.另外,don’t use query_posts.最后,存储帖子标题并不理想,因为它可能会改变,ID是永久性的.
一份工作样本：
# PHP 5.3+ anonymous function
add_action( 'widgets_init', function() {
register_widget( 'Sample_Widget_SO_19246434' );
});
class Sample_Widget_SO_19246434 extends WP_Widget
{
function Sample_Widget_SO_19246434()
{
$this->WP_Widget(
'hottopics',
__('Hot Topics'),
array(
'name' => 'Hot Topics',
'classname' => 'widget-hot-topics',
'description' => __( "Description" )
)
);
}
function form( $instance )
{
if( $instance )
$select = $instance['select'];
else
$select ='';
$get_posts = get_posts( array(
'offset'=> 1,
'orderby' => 'date',
'order' => 'DESC',
'posts_per_page' => 200,
'post_status' => 'publish'
));
if( $get_posts )
{
printf(
'<select multiple="multiple" name="%s[]" id="%s"size="15">',
$this->get_field_name('select'),
$this->get_field_id('select')
);
foreach( $get_posts as $post )
{
printf(
'<option value="%s"%shttps://www.jb51.cc/tag/ott/" target="_blank">ottom:3px;">%s</option>',
$post->ID,
in_array( $post->ID, $select) ? 'selected="selected"' : '',
$post->post_title
);
}
echo '</select>';
}
else
echo 'No posts found :(';
}
function update( $new_instance, $old_instance )
{
$instance = $old_instance;
$instance['select'] = esc_sql( $new_instance['select'] );
return $instance;
}
function widget( $args, $instance )
{
echo 'Hello world';
}
}

php – wordpress自定义查询选择元值
SELECT b.post_title, a.post_id, COUNT( * ) as Total
FROM wp_posts b INNER JOIN
wp_postMeta a ON a.post_id = b.ID
WHERE a.Meta_value = 1
AND a.Meta_key = 'type-select'
AND b.post_status = 'publish'
and post_type = 'car-cc'
GROUP BY b.post_title, a.post_id
目前它选择帖子标题和帖子ID,但我还需要选择元值,其中元键=类型 – 问题是另一个元键已经在查询中进行了比较.
sql小提琴：http://sqlfiddle.com/#!2/109c2/1
解决方法:
干得好
SELECT b.post_title, a.post_id, COUNT( * ) AS Total,
(SELECT Meta_value FROM `wp_postMeta` WHERE post_id= b.ID AND Meta_key='type-gen') AS 'new Meta value'
FROM wp_posts b INNER JOIN
wp_postMeta a ON a.post_id = b.ID
WHERE a.Meta_value = 1
AND a.Meta_key = 'type-select'
AND b.post_status = 'publish'
AND post_type = 'car-cc'
GROUP BY b.post_title, a.post_id

php – 在我自己的自定义插件中添加wordpress admin中的分页
我想在我的插件页面中显示分页,由我创建..我尝试了很多例子,但没有人工作..
如果有人能给出答案我会感激不尽的…
注意：我希望在后端(在管理员中)不在前端进行分页
解决方法:
简单步骤：
$pagenum = isset( $_GET['pagenum'] ) ? absint( $_GET['pagenum'] ) : 1;
查找记录总数
$limit = 10; // number of rows in page
$offset = ( $pagenum - 1 ) * $limit;
$total = $wpdb->get_var( "SELECT COUNT(`id`) FROM {$wpdb->prefix}table_name" );
$num_of_pages = ceil( $total / $limit );
给予限制：
$entries = $wpdb->get_results( "SELECT * FROM {$wpdb->prefix}table_name LIMIT $offset, $limit" );
将此代码添加到您想要分页的位置：
$page_links = paginate_links( array(
'base' => add_query_arg( 'pagenum', '%#%' ),
'format' => '',
'prev_text' => __( '«', 'text-domain' ),
'next_text' => __( '»', 'text-domain' ),
'total' => $num_of_pages,
'current' => $pagenum
) );
if ( $page_links ) {
echo '<div><div>' . $page_links . '</div></div>';
}
