在选择菜单中比较当前帖子类别

我已经做过很多次了，但不是通过表格，所以当我试图根据当前的学期后id分配一个“选定的”时，我遇到了一个奇怪的问题。。。

可能是使用_the_category 然后get_categories 制造冲突？有人知道为什么会这样吗？

无论所选项目是最后一个项目，而不是当前帖子（通过外部表单获取帖子id）类别

这是我的代码：

<?php 
$postId = $_POST[\'postid\']; // the value is recieved properly
$currentCategory = get_the_category($postId);  // the value is recieved properly
$currentCategoryId = $currentCategory[0]->term_id; // the value is assigned properly

$categories = get_categories(\'hide_empty=0\'); // the value is recieved properly
$optionname = "postcats"; // the value is recieved properly
$emptyvalue = "";

// SELECET DROP DOWN TERMS
echo \'<select name="\'.$optionname.\'" class="clientList"><option selected="\'.$selected.\'" value="\'.$emptyvalue.\'">\'.__(\'Choose a category\',\'sagive\').\'</option>\';
foreach($categories as $category){
    // next line seem to not work!
    if($currentCategoryId == $category->term_id) {$selected = \'selected="selected"\';}
    echo \'<option name="\'.$category->term_id.\'" value="\'.$category->term_id.\'" \'.$selected.\'>\'.$category->name.\'</option>\';
}

echo \'</select>\';
?>

if i try to echo the $currentCategoryId outside the foreach it works
but not inside it.. kinda weird!

<?php $postId = $_POST[\'postid\']; // the value is recieved properly $currentCategory = get_the_category($postId); // the value is recieved properly $currentCategoryId = $currentCategory[0]->term_id; // the value is assigned properly $categories = get_categories(\'hide_empty=0\'); // the value is recieved properly $optionname = "postcats"; // the value is recieved properly $emptyvalue = ""; // SELECET DROP DOWN TERMS echo \'<select name="\'.$optionname.\'" class="clientList"><option selected="\'.$selected.\'" value="\'.$emptyvalue.\'">\'.__(\'Choose a category\',\'sagive\').\'</option>\'; foreach($categories as $category){ // HERE I ENTERED AN ELSE THAT WOULD CLEAN // THE VALUE OF $SELECTED if($currentCategoryId == $category->term_id) {$selected = \'selected="selected"\';} else {$selected = \'\'} echo \'<option name="\'.$category->term_id.\'" value="\'.$category->term_id.\'" \'.$selected.\'>\'.$category->name.\'</option>\'; } echo \'</select>\'; ?>

wp_list_categories pagination

我想知道我是否可以为wp\\U list\\U类别分页？我尝试了paginate\\u链接，但运气不好。还是有好的解决方法？非常感谢。<?php $orderby = \'name\'; $show_count = 0; $pad_counts = 0; $hierarchical = 1; $taxonomy = \'categories\'; $title = \'\'; $exclude = \
