如何使用PHP和mysql通过id打开一个新页面？

Question

I have a table (mysql): Optional table caption.

 <table class="table"> <caption>myTable</caption> <thead> <tr> <th>ID</th> <th>First Name</th> <th>Last Name</th> <th>Username</th> </tr> </thead> <tbody> <tr> <th scope="row">1</th> <td>Mark</td> <td>Otto</td> <td>@mdo</td> </tr> <tr> <th scope="row">2</th> <td>Jacob</td> <td>Thornton</td> <td>@fat</td> </tr> <tr> <th scope="row">3</th> <td>Larry</td> <td>the Bird</td> <td>@twitter</td> </tr> </tbody> </table> 

I have a persons.php page that pull out all person's name from that table, and showing like this:

 <div> <p>Name: Mark Otto <a href="#">View</a></p> <p>Name: Jacob Thornton <a href="#">View</a></p> <p>Name: Larry the Bird <a href="#">View</butaon></p> </div> 

And I have a detailed.php that shows person's username, like this:

 <div> <p>ID: ?</p> <p>First name: ?</p> <p>Last name: ?</p> <p>User name: ?</p> </div> 

My question is that how to get detailed.php page by id when click the 'View' link?

Sorry, I am learning PHP, my point is when click the view link, what is the way to get the detailed.php displayed by the ID. I know how to get data displayed while using php+mysql, but I don't know how to perform the click action and direct to detailed.php page that showing info by id.

Thanks!

Answer 1

Replace the <button by <a href . In "persons.php" you will need to echo the ID in the <a href , later, in "detailed.php", you get the value as $_GET[ "id" ] :

persons.php

  <div>
    Name: Larry the Bird <a href="detailed.php?id=<?php echo $id;?>">View</a>

detailed.php

<?php
if ( isset( $_GET[ "id" ] ) )
   echo "<p>ID: " . $_GET[ "id" ] . "</p>";
?>

Try this! put your query instead of'$yourquery'

persons.php

<?php
<table>
    <thead>
      <tr>
        <th># </th>
        <th>Name</th> 
        <th>Action</th> 
      </tr>
    </thead>
    <tbody>
    while($row=mysql_fetch_array($yourquery))
    {
    ?>
    <tr> 
      <td>Name : <?=$row['name']?>  <?=$row['lastname']?></td> 
      <form method="GET" action="detailed.php">
        <input type="hidden" value="<?=$row['id']?>" name="id" />
            <td><button type="submit">View</button></td>
      </form>
    </tr> 
  <?php
    }
    ?>
  </tbody>
</table>
