现在我已经创建类别并且创建帖子成功但是当我编辑我的帖子时我有问题如果编辑我的帖子我会丢失我的类别..我需要在表格中获取我的类别并且我可以更改它
<?php
$sql = "SELECT catid, catname, parentid FROM categories";
$res = mysql_query($sql);
// initialize $categories to make sure it is an array
$categories = array();
while ($row = mysql_fetch_assoc($res)) {
$parent = intval($row['parentid']);
$categories[$parent][] = $row;
}
?>
<table border="0" cellpadding="10" cellspacing="0">
<tr>
<td valign="top">
<?php
$category_string = "";
function build_categories_options($parent, $categories, $level) {
global $category_string;
if (isset($categories[$parent]) && count($categories[$parent])) {
$level .= " - ";
foreach ($categories[$parent] as $category) {
$opt_value = substr($level.$category['catname'],3);
$category_string .= '<option value=""></option><option value="'.$category['catid'].'">'.$opt_value.'</option>';
build_categories_options($category['catid'], $categories, $level);
}
$level = substr($level, -3);
}
return $category_string;
}
$category_options = build_categories_options(0, $categories, '');
$category_options = '<select class="chosen" name="categories" id="categories">'.$category_options.'</select>';
echo $category_options;
?>
</td>
我的问题位于第 25 行
$category_string .= '<option value=""></option><option value="'.$category['catid'].'">'.$opt_value.'</option>';
我需要首先获得我的类别并显示其余结果。
