Running to Selects and grouping results with PHP - php

Question

I am trying to display a row of data from my main table (parents details) and then under each of those rows display the children's names from another table. I have had a go using the following code:
$sql="select distinct members_main.first_name as main_firstname,
members_main.first_name as main_firstname,
members_main.last_name as main_lastname,
members_main.address_1 as main_address_1,
members_main.address_2 as main_address_2,
members_main.address_3 as main_address_3,
members_main.address_4 as main_address_4,
members_main.post_code as main_post_code,
members_main.home_tel as main_home_tel,
members_main.mobile as main_mobile,
members_main.home_email as main_home_email
from members_main, members_family where members_main.contact_id=members_family.contact_id";
$sql2="select members_family.first_name as fam_firstname,
members_family.last_name as fam_lastname
from members_family, members_main
where members_main.contact_id=members_family.contact_id";
$result=mysql_query($sql);
while($rows=mysql_fetch_array($result)){
echo '<table width="100%" cellpadding="3" cellspacing="0">
<tr>
<th align="left" valign="top">First Name</th>
<th align="left" valign="top">Last Name</th>
<th align="left" valign="top">Address 1</th>
<th align="left" valign="top">Address 2</th>
<th align="left" valign="top">Address 3</th>
<th align="left" valign="top">Address 4</th>
<th align="left" valign="top">Post Code</th>
<th align="left" valign="top">Home Tel</th>
<th align="left" valign="top">Mobile</th>
<th align="left" valign="top">Email</th>
</tr>';
echo '<tr>
<td valign="top">'.$rows['main_firstname'].'</td>
<td valign="top">'.$rows['main_lastname'].'</td>
<td valign="top">'.$rows['main_address_1'].'</td>
<td valign="top">'.$rows['main_address_2'].'</td>
<td valign="top">'.$rows['main_address_3'].'</td>
<td valign="top">'.$rows['main_address_4'].'</td>
<td valign="top">'.$rows['main_post_code'].'</td>
<td valign="top">'.$rows['main_home_tel'].'</td>
<td valign="top">'.$rows['main_mobile'].'</td>
<td valign="top">'.$rows['main_home_email'].'</td>
</tr>';
$result2=mysql_query($sql2);
echo '<table width="100%" cellpadding="3" cellspacing="0">
<tr>
<th align="left" valign="top">First Name</th>
<th align="left" valign="top">Last Name</th>
</tr>';
while($rows=mysql_fetch_array($result2)){
echo '<tr>
<td valign="top">'.$rows['fam_firstname'].'</td>
<td valign="top">'.$rows['fam_lastname'].'</td>
</tr>';
}
}
echo "</table>";
I am getting all rows from the members_family table per each record from the members_main. There can be more than one record in the members_family which will be associated to one record in the members_main. Bascially, members_main (parent) can have multiple children in the members_main.

Answer 1

I think you just need to retrieve your members_main.contact_id from first table to use later in second while loop. Then you will have to move your second query inside first query while loop so the code will look like that:
$sql="select distinct
members_main.contact_id as ID,
members_main.first_name as main_firstname,
members_main.first_name as main_firstname,
members_main.last_name as main_lastname,
members_main.address_1 as main_address_1,
members_main.address_2 as main_address_2,
members_main.address_3 as main_address_3,
members_main.address_4 as main_address_4,
members_main.post_code as main_post_code,
members_main.home_tel as main_home_tel,
members_main.mobile as main_mobile,
members_main.home_email as main_home_email
from members_main, members_family where members_main.contact_id=members_family.contact_id";
$result = mysql_query($sql);
while($rows=mysql_fetch_array($result)) {
//script goes on with table printing untill
<td valign="top">'.$rows['main_home_email'].'</td>
</tr>';
Now it's time for the query
$sql2="select members_family.first_name as fam_firstname,
members_family.last_name as fam_lastname
from members_family, members_main
where members_main.contact_id=members_family.contact_id and members_main.contact_id = '".$rows['ID']."'";
As you see i added in WHERE condition to limit result for specified ID wich i retrieved from first query. Now you can print the rest of the table. Oh and by the way you closing table should look like that
echo "</table></td></tr></table>";
This is because you opened two tables.
Then I would like you to remember that mysql_* functions are deprecated so i would advise you to switch to mysqli or PDO

Answer 2

I feel some confusion with your second query. I am thinking that you have to construct your second query with the contact_id which is coming from first query(members_main). I assumes in that way and i have coded below. May be it will help you
<?php
$sql = "select distinct members_main.first_name as main_firstname,
members_main.first_name as main_firstname,
members_main.last_name as main_lastname,
members_main.address_1 as main_address_1,
members_main.address_2 as main_address_2,
members_main.address_3 as main_address_3,
members_main.address_4 as main_address_4,
members_main.post_code as main_post_code,
members_main.home_tel as main_home_tel,
members_main.mobile as main_mobile,
members_main.home_email as main_home_email
from members_main, members_family where members_main.contact_id=members_family.contact_id";
$result = mysql_query($sql);
?>
<table width="100%" cellpadding="3" cellspacing="0">
<tr>
<th align="left" valign="top">First Name</th>
<th align="left" valign="top">Last Name</th>
<th align="left" valign="top">Address 1</th>
<th align="left" valign="top">Address 2</th>
<th align="left" valign="top">Address 3</th>
<th align="left" valign="top">Address 4</th>
<th align="left" valign="top">Post Code</th>
<th align="left" valign="top">Home Tel</th>
<th align="left" valign="top">Mobile</th>
<th align="left" valign="top">Email</th>
</tr>
<?php
while ($rows = mysql_fetch_array($result))
{
$conId = $rows['contact_id']; //Which is comming from first Query
$sql2 = "select members_family.first_name as fam_firstname,
members_family.last_name as fam_lastname
from members_family, members_main
where members_family.contact_id=$conId";
$result2 = mysql_query($sql2);
?>
<tr>
<td valign="top"><?= $rows['main_firstname']; ?></td>
<td valign="top"><?= $rows['main_lastname']; ?></td>
<td valign="top"><?= $rows['main_address_1']; ?></td>
<td valign="top"><?= $rows['main_address_2']; ?></td>
<td valign="top"><?= $rows['main_address_3']; ?></td>
<td valign="top"><?= $rows['main_address_4']; ?></td>
<td valign="top"><?= $rows['main_post_code']; ?></td>
<td valign="top"><?= $rows['main_home_tel']; ?></td>
<td valign="top"><?= $rows['main_mobile']; ?></td>
<td valign="top"><?= $rows['main_home_email']; ?></td>
</tr>
<tr>
<td colspan="10">
<table width="100%" cellpadding="3" cellspacing="0">
<tr>
<th align="left" valign="top">First Name</th>
<th align="left" valign="top">Last Name</th>
</tr>
<?php
while ($rowsFamily = mysql_fetch_array($result2))
{
?>
<tr>
<td valign="top"><?= $rowsFamily['fam_firstname']; ?></td>
<td valign="top"><?= $rowsFamily['fam_lastname']; ?></td>
</tr>
<?php
}
?>
</table>
</td>
</tr>
<?php
}
?>
</table>
