我发现我的函数有一种奇怪的行为。

我想把身份证从display_rows() 到column_cb(), 但问题是程序只传递第一个数字。有什么提示吗？

column_cb():

function column_cb($item) {
    return sprintf(\'<input type="checkbox" name="id[]" value="%s" />\', $item[\'id\']);
}

function display_rows() {
    $records = $this->items;
    list( $columns, $hidden ) = $this->get_column_info();

    if(!empty($records)){
        foreach($records as $rec) {
            echo \'<tr id="record_\'.$rec->id.\'">\';
            foreach ( $columns as $column_name => $column_display_name ) {
                $class = "class=\'$column_name column-$column_name\'";
                $style = "";
                if ( in_array( $column_name, $hidden ) ) $style = \'style="display:none;"\';
                    $attributes = $class . $style;
                    $editlink  = \'/wp-admin/link.php?action=edit&id=\'.(int)$rec->id;

                    //Display the cell
                    switch ( $column_name ) {
                        case "cb":  echo \'<th scope="row" class="check-column">\'.$this->column_cb(stripslashes($rec->id)).\'</th>\'; break;
                        case "col_name":    echo \'<td \'.$attributes.\'><strong>\'.$this->column_title(stripslashes($rec->product_name_name)).\'</strong></td>\'; break;
                    }
             }
                    echo\'</tr>\';
        }
     }
 }

column_title():

function column_title($item){
    $actions = array(
                     \'edit\'      => sprintf(\'<a href="?page=%s&action=%s&product=%s">Edit</a>\',$_REQUEST[\'page\'],\'edit\',$item[\'ID\']),
                     \'delete\'    => sprintf(\'<a href="?page=%s&action=%s&product=%s">Delete</a>\',$_REQUEST[\'page\'],\'delete\',$item[\'ID\']),
        );

       //Return the title contents
       return sprintf(\'<a href="#"><b>%1$s</b></a> %3$s\',
            /*$1%s*/ $item[\'product_name\'],
            /*$2%s*/ $item[\'id\'],
            /*$3%s*/ $this->row_actions($actions)
        );
    }
