当我单击显示按钮时显示特定数据

Question

i have problem on how to display specific details only. let say for example i have two table salessumarry and rsales and have this ff data for its table.

data from rsales

id | name | last_name | age | salessumarry_id |
1  |gejel | rosenthal | 21  |        5        |

data from salessumarry (note: this data is from database display to my webpage)

id | or_no | sold_by | detail |
5  | 12456 |  fabbie | show   |
6  | 22222 |  nedy   | show   |

my problem is this. when i click "show" from my webpage it must select data from rsales where salessumarry_id = salessumarry.id. let say for example i click show for id 5 the expected output must be something like this

id | or_no | sold_by | detail |
5  | 12456 |  fabbie | show   |
id | name | last_name | age | salessumarry_id |
1  |gejel | rosenthal | 21  |        5        |
6  | 22222 |  nedy   | show   |

i put this in my "show" button but my idea is up to only this point. i don't have idea how to display details when i click show

echo '<td style="border-color:#000000; border-style:solid; border-width:1px;"><div align="center"><a  href=displaydetail.php?id=' . $row['id'] .'>show</a></div></td>';

Answer 1

This is a basic way to accomplish what you are trying to do:

displaydetail.php
<?php
    // get salessumarry_id  from the URL
    $salessumarry_id = $_GET['id'];
    $query = "SELECT * FROM rsales WHERE salessumarry_id = '$salessumarry_id'";

    // use mysqli/pdo here to to execute the query 
    // and fetch the results into $results array and display it here:
    echo "id | name | last_name | age | salessumarry_id |<br>";
    echo $results['id']. " | ". $results['name']." | ".$results['last_name']." | ";
    echo $results['age']." | ".$results['salessumarry_id']." | ";
?>

Hope this helps. This can be further improved but first you need to make sure that this part is working.
