你能幫我弄這個麪包屑導航工作嗎？我的PHP不好。我仍在學習。麪包屑導航
這是我在MySQL
cats_id cats_position cats_parentid
1 1> 0
2 1>2> 1
3 3> 0
4 1>2>4> 2
我想是這樣的貓，但它是不正確的方法。你能不能讓我看看正確的方法。
$pieces = explode(">", $position);
if ($pieces[0] != "")
{
$result = mysql_query("SELECT * FROM cats
WHERE cats_id='$pieces[0]'");
while($row = mysql_fetch_array($result))
{
$piecesid0 = $row['cats_id'];
$piecesname0 = $row['cats_name'];
$piecesposition0 = $row['cats_position'];
}
}
if ($pieces[1] != "")
{
$result = mysql_query("SELECT * FROM cats
WHERE cats_id='$pieces[1]'");
while($row = mysql_fetch_array($result))
{
$piecesid1 = $row['cats_id'];
$piecesname1 = $row['cats_name'];
$piecesposition1 = $row['cats_position'];
}
}
if ($pieces[2] != "")
{
$result = mysql_query("SELECT * FROM cats
WHERE cats_id='$pieces[2]'");
while($row = mysql_fetch_array($result))
{
$piecesid2 = $row['cats_id'];
$piecesname2 = $row['cats_name'];
$piecesposition2 = $row['cats_position'];
}
}
if ($pieces[3] != "")
{
$result = mysql_query("SELECT * FROM cats
WHERE cats_id='$pieces[3]'");
while($row = mysql_fetch_array($result))
{
$piecesid3 = $row['cats_id'];
$piecesname3 = $row['cats_name'];
$piecesposition3 = $row['cats_position'];
}
}
