嗨，伙计们，我对此很头疼，我对本教程wpshout进行了多检查。com/在wordpress中创建一个in-post主题选项元框/问题是它没有保存所有选中的值，并且在编辑帖子时也没有选中选中的值。
这是我的密码
我在这里为muticheckbox添加了一个数组
<?php function hybrid_post_meta_boxes() {
/* Array of the meta box options. */
$meta_boxes = array(
\'title\' => array( \'name\' => \'Title\', \'title\' => __(\'Title\', \'hybrid\'), \'type\' => \'text\' ),
\'description\' => array( \'name\' => \'Description\', \'title\' => __(\'Description\', \'hybrid\'), \'type\' => \'textarea\' ),
\'location\' => array( \'name\' => \'location\', \'title\' => __(\'Location:\', \'hybrid\'), \'type\' => \'check\', \'options\' => array(
\'AL\' => \'Alabama\',
\'CA\' => \'California\',
\'DE\' => \'Delaware\',
),
);
return apply_filters( \'hybrid_post_meta_boxes\', $meta_boxes ); } ?>
我为多重复选框添加else语句
<?php
function post_meta_boxes() {
global $post;
$meta_boxes = hybrid_post_meta_boxes(); ?>
<table class="form-table">
<?php foreach ( $meta_boxes as $meta ) :
$value = get_post_meta( $post->ID, $meta[\'name\'], true );
if ( $meta[\'type\'] == \'text\' )
get_meta_text_input( $meta, $value );
elseif ( $meta[\'type\'] == \'textarea\' )
get_meta_textarea( $meta, $value );
elseif ( $meta[\'type\'] == \'select\' )
get_meta_select( $meta, $value );
elseif ( $meta[\'type\'] == \'check\' )
get_meta_check( $meta, $value );
endforeach; ?>
</table>
我为multicheck创建了一个函数
<?php function get_meta_check( $args = array(), $value = false ) {
extract( $args ); ?>
<tr>
<th style="width:10%;">
<label for="<?php echo $name; ?>"><?php echo $title; ?></label>
</th>
<td>
<?php foreach ( $options as $option ) : ?>
<input type="checkbox" name="<?php echo $name; ?>" id="<?php echo $name; ?>" value=", <?php echo $option; ?>, " <?php if ( htmlentities( $value, ENT_QUOTES ) == $option ) echo \' checked="checked"\'; ?> /> <?php echo $option; ?>,
<?php endforeach; ?>
<input type="hidden" name="<?php echo $name; ?>_noncename" id="<?php echo $name; ?>_noncename" value="<?php echo wp_create_nonce( plugin_basename( __FILE__ ) ); ?>" />
</td>
</tr>
<?php } ?>
如何编写代码来保存复选框的所有值？谢谢
使现代化
function save_meta_data( $post_id ) {
global $post;
if ( \'page\' == $_POST[\'post_type\'] )
$meta_boxes = array_merge( page_meta_boxes() );
else
$meta_boxes = array_merge( post_meta_boxes() );
foreach ( $meta_boxes as $meta_box ) :
if ( !wp_verify_nonce( $_POST[$meta_box[\'name\'] . \'_noncename\'], plugin_basename( __FILE__ ) ) )
return $post_id;
if ( \'page\' == $_POST[\'post_type\'] && !current_user_can( \'edit_page\', $post_id ) )
return $post_id;
elseif ( \'post\' == $_POST[\'post_type\'] && !current_user_can( \'edit_post\', $post_id ) )
return $post_id;
$data = stripslashes( $_POST[$meta_box[\'name\']] );
if ( get_post_meta( $post_id, $meta_box[\'name\'] ) == \'\' )
add_post_meta( $post_id, $meta_box[\'name\'], $data, true );
elseif ( $data != get_post_meta( $post_id, $meta_box[\'name\'], true ) )
update_post_meta( $post_id, $meta_box[\'name\'], $data );
elseif ( $data == \'\' )
delete_post_meta( $post_id, $meta_box[\'name\'], get_post_meta( $post_id, $meta_box[\'name\'], true ) );
endforeach;
} ?>
最合适的回答,由SO网友:Jan Fabry 整理而成
我拿走了the example code you suggested 并更改了以下内容以获得multicheck支持：
// Add this at the end of the file
// A good prefix for your name prevents problems later!
function wpse6513_get_meta_check( $args = array(), $current_values = array() )
{
extract( $args );
$name_esc = esc_attr( $name );
if ( ! is_array( $current_values ) ) {
$current_values = array();
}
echo \'<tr>\';
echo \'<th style="width: 10%">\';
echo \'<label for="\' . $name_esc . \'">\' . esc_html( $title ) . \'</label>\';
echo \'</th>\';
echo \'<td>\';
foreach ( $options as $option_value => $option_label ) {
$option_value_esc = esc_attr( $option_value );
echo \'<label><input type="checkbox" name="\' . $name_esc . \'[]" id="\' . $name_esc . \'_\' . $option_value_esc . \'" value="\' . $option_value_esc . \'"\';
if ( in_array( $option_value, $current_values ) ) {
echo \' checked="checked"\';
}
echo \'/> \' . esc_html( $option_label );
echo \'</label><br/>\';
}
echo \'<input type="hidden" name="\' . $name_esc . \'_noncename" id="\' . $name_esc . \'_noncename" value="\' . wp_create_nonce( plugin_basename( __FILE__ ) ) . \'" />\';
echo \'</td>\';
echo \'</tr>\';
}
在中
hybrid_save_meta_data():
// Replace this line:
$data = stripslashes( $_POST[$meta_box[\'name\']] );
// By these lines:
$data = array_key_exists( $meta_box[\'name\'], $_POST ) ? $_POST[$meta_box[\'name\']] : \'\';
if ( is_array( $data ) ) {
$data = array_map( \'stripslashes\', $data );
} else {
$data = stripslashes( $data );
}
当然，在
post_meta_boxes():
// Add this to the `$meta[\'type\']` if/else list
elseif ( $meta[\'type\'] == \'check\' )
wpse6513_get_meta_check( $meta, $value );
现在，您可以处理您建议的表单的“多检查”：
\'location\' => array(
\'name\' => \'location\',
\'title\' => __(\'Location:\', \'hybrid\'),
\'type\' => \'check\',
\'options\' => array(
\'AL\' => \'Alabama\',
\'CA\' => \'California\',
\'DE\' => \'Delaware\',
),
),
最后是一些防止警告的代码（除非启用
WP_DEBUG):
// Replace all `wp_specialchar()` calls with `esc_attr()`
// Add these lines in `hybrid_save_meta_data()`:
// At the start, after `global $post`:
if ( ! array_key_exists( \'post_type\', $_POST ) ) {
return $post_id;
}
// In the foreach loop, instead of:
if ( !wp_verify_nonce( $_POST[$meta_box[\'name\'] . \'_noncename\'], plugin_basename( __FILE__ ) ) )
return $post_id;
// Write:
$nonce_name = $meta_box[\'name\'] . \'_noncename\';
if ( ! array_key_exists( $nonce_name, $_POST ) || !wp_verify_nonce( $_POST[$nonce_name], plugin_basename( __FILE__ ) ) )
return $post_id;
