Error sending array of inputs

时间：2013-07-18 作者：user1073323

您好，我收到Wordpress includes的一个错误，当我发布分类法的多个值时会出现此错误

<form role="search" method="post" id="searchform" action="<?php echo home_url( \'/\' ); ?>">

<select name="books[]" multiple>
  <option value="a">a</option>
  <option value="b">b</option>
</select>
<input type="submit" id="searchsubmit" value="Search" />
</form>

警告：strpos（）要求参数1为字符串，数组在www.domain中给出。com\\wordpress\\wp包含\\查询。php在线1718警告：preg\\u split（）要求参数2为字符串，数组在www.domain中给出。com\\wordpress\\wp包含\\查询。php联机1719警告：为www.domain中的foreach（）提供的参数无效。com\\wordpress\\wp包含\\查询。php联机1720

    foreach ( $GLOBALS[\'wp_taxonomies\'] as $taxonomy => $t ) {
        if ( \'post_tag\' == $taxonomy )
            continue;   // Handled further down in the $q[\'tag\'] block

        if ( $t->query_var && !empty( $q[$t->query_var] ) ) {
            $tax_query_defaults = array(
                \'taxonomy\' => $taxonomy,
                \'field\' => \'slug\',
            );

            if ( isset( $t->rewrite[\'hierarchical\'] ) && $t->rewrite[\'hierarchical\'] ) {
                $q[$t->query_var] = wp_basename( $q[$t->query_var] );
            }

            $term = $q[$t->query_var];

            if ( strpos($term, \'+\') !== false ) {
                $terms = preg_split( \'/[+]+/\', $term );
                foreach ( $terms as $term ) {
                    $tax_query[] = array_merge( $tax_query_defaults, array(
                        \'terms\' => array( $term )
                    ) );
                }
            } else {
                $tax_query[] = array_merge( $tax_query_defaults, array(
                    \'terms\' => preg_split( \'/[,]+/\', $term )
                ) );
            }
        }
    }

当我将其发布到searchresults时，该错误不会出现。php或当我使用单一值或无分类名称时；

<select name="books">
<select name="NoneTaxonomyName[]" multiple>

有人知道如何解决这个问题吗？

solved with; query_var => false

register_taxonomy(\'taxname\', \'post_type\', array(\'hierarchical\' => true, \'label\' => \'lable\',     \'query_var\' => false, \'rewrite\' => array(\'slug\' => \'slug\')));

正如我在上面的评论中所说，设置query_var => false 因为自定义分类法不是解决方案，因为这将使前端中的术语页返回404错误。放弃在前端使用术语页面，使其成为一个简单的工作表单，这远远不是一个解决方案。

我终于解决了这个问题。我没有将select元素中的名称设置为“my\\u tax[]”，而是将其设置为类似“tax\\u input[\'my\\u tax\']”[]。不要问我为什么Wordpress需要这个，但它解决了问题。

如果有人需要一个例子。

我的示例分类：

$taxonomies = array(
            \'type\'               => array(\'label\' => \'Types\',\'slug\' => \'type\',\'hierarchical\' => false,\'multiple\' => false),
            \'city\'               => array(\'label\' => \'Cities\',\'slug\' => \'city\',\'hierarchical\' => true,\'multiple\' => false),
            \'community_features\' => array(\'label\' => \'Community features\',\'slug\' => \'community_features\',\'hierarchical\' => false,\'multiple\' => true),
            \'property_features\'  => array(\'label\' => \'Property features\',\'slug\' => \'property_features\',\'hierarchical\' => false,\'multiple\' => true)
    ); 

   foreach($taxonomies as $taxonomy => $properties){
        register_taxonomy(
                         $taxonomy,
                         \'properties\',
                         array(
                              \'label\'        => __( $properties[\'label\'] ),
                              \'hierarchical\' => $properties[\'hierarchical\'],
                              \'query_var\'    => true,
                              )
                          );

         register_taxonomy_for_object_type( $taxonomy, \'properties\' );

}

这里是一个示例表单：

           <form method="post" action="<?php echo get_post_type_archive_link(\'properties\');?>">
             <?php
               foreach($taxonomies as $taxonomy) {
                   $args = array(
                                \'show_option_all\'    => __(\'Select \'.$taxonomy[\'label\'],\'properties\'),
                                \'orderby\'            => \'NAME\', 
                                \'order\'              => \'ASC\',
                                \'hide_empty\'         => 0, 
                                \'echo\'               => 0,
                                \'selected\'           => \'\',
                                \'hierarchical\'       => true, 
                                \'name\'               => \'tax_input[\'.$taxonomy[\'slug\'].\'][]\',
                                \'class\'              => \'\',
                                \'taxonomy\'           => $taxonomy[\'slug\'],
                             );

                 if($taxonomy[\'multiple\']){
                   $args[\'show_option_all\'] = \'\';
                 }
                 $select = wp_dropdown_categories( $args );

                 if($taxonomy[\'multiple\']){
                   $select = preg_replace("#<select([^>]*)>#", "<select$1 multiple>", $select);
                 }

                 echo $select;
               }
             ?>
             <input type="hidden" name="action" id="action" value="search">
             <button type="submit"><?php _e(\'Search\',\'properties\');?></button>
           </form>

添加了自定义查询变量：

add_filter(\'query_vars\', \'properties_add_query_vars\');
function properties_add_query_vars( $vars) {
   $vars[] = "action"; // name of the var as seen in the URL
   return $vars;
}

我的示例pre\\u get\\u帖子：

add_action( \'pre_get_posts\', \'properties_pre_get_post\' );
function properties_pre_get_post($query){

  if(isset($query->query_vars[\'action\']) && $query->query_vars[\'action\'] == \'search\'){

     if($query->is_main_query() && !is_admin() && $query->is_archive ) {

        $tax_query = array();

        $tax_input = $_POST[\'tax_input\'];
        if(!empty($tax_input)){

           foreach($tax_input as $key => $value){
              if(array_key_exists($key, $taxonomies)){
                 if(!empty($value) && $value[0] != "0"){
                    $value = array_map(\'intval\', $value);
                $tax_query[] = array(
                                         \'taxonomy\' => $key,
                                         \'field\'    => \'id\',
                                         \'terms\'    => $value,
                                         \'operator\' => \'AND\'
                                   );
                 }
              }
            }
         $query->set(\'tax_query\',$tax_query);
       }
    }
  }
}

结束
