Question

I have a slight dilemma on my hands. This is the situation. On a webpage, I am using a php while loop to read data into a page from a database. That works fine but I need each of this items when clicked, go to another webpage with more info on them. This more info is just data that i will have on another column in database so its no biggie. So my dilemma is how do I know which item is clicked. Is there a way to track which unique index was clicked? (Keep in mind that I might me listing thousands of items on the page).

这是我的时空密码

while($row = mysql_fetch_array($result)){
 echo  <div class="thumb"> ;
 echo  <a href="template.php"><img src= .$row[ dresses_pic ]. /></a> ;
 echo  <p> .$row[ price_ ]. </p> ;
 echo  </div> ;
}

I have tried putting a SESSION inside the while loop but the next page always reads the last listing as the item.
Is there a better way to achieve what am trying to do?
Thanks

Answer 1

只需在链接中附加项目编号,然后从下一页上以 $_GET 变量的形式获取 :

while($row = mysql_fetch_array($result)){
 echo  <div class="thumb"> ;
 echo  <a href="template.php?id= .$row[ id ]. "><img src= .$row[ dresses_pic ]. /></a> ;
 echo  <p> .$row[ price_ ]. </p> ;
 echo  </div> ;
}

< 坚固> 模板.php

$id = (int) $_GET[ id ]; // Use this to get the item from the DB

Answer 2

尝试通过行项的 ID, 然后在新页面上取回该 ID 的数据。

 echo  <a href="template.php?id= .$row[ id ]. "><img src= .$row[ dresses_pic ]. /></a> ;

Answer 3

将记录代号传送到下一页(使用 URL 参数最简单, < code>?id=xxxx ),并查询 db 使用 id (您可以通过 $_GET[ id] 获得信息)。

Answer 4

使用查询字符串将项目 ID 传送到您的模板.php 页面。

while($row = mysql_fetch_array($result)){
 echo  <div class="thumb"> ;
 echo  <a href="template.php?id= .$row[ item_id ]. "><img src= .$row[ dresses_pic ]. /></a> ;
 echo  <p> .$row[ price_ ]. </p> ;
 echo  </div> ;
}
