PHP DROP DOWN POPULATED BY MYSQL

Hello Experts,

Thank you for your time,

Im really stuck here, What im after is a PHP drop down box which is populated from my MYSQL database. this database could consist of the following.

Asda
Tesco
Morrisons
Sainsburys

etc etc

The drop down needs to "select * from company" and place it into the drop down menu to be selected.

a button is then clicked which posts the selected STORE into the next page where it is SEARCHED for in the database and the STORE details are then listed inside a new page.

The Store details would be located in another table for example.

Company_address

Asda 13 Leeds court
Tesco blah blah

You get the picture... based on the entry selected the following store address must be returned.. and none of the others..

Is this possible??

Many thanks

All input is appricated.

Absolutely, Here is sample code for populating your drop-down box:

<select id="ddlCompanies">
<?php
$sql = "SELECT company_name FROM company ORDER BY company_name";
$rs = mysql_query($sql);
while($row = mysql_fetch_array($rs)) {
   echo ("<option>" . $row['company_name'] . "</option>");
}
?>
</select>
<br />
<input type="button" onclick="var val = document.getElementById('ddlCompanies').options[document.getElementById('ddlCompanies').selectedIndex].value; var url = 'companyInfo.php?val=';url+=val;window.location=url;" value="Submit..." />

Open in new window

Then to get the selected info from the db you could do something like this using the selected value from the URL parameter in the companyInfo.php page like this:

$val = $_GET['val'];
$sql = "SELECT store_address, store_phone FROM stores WHERE store_name = '" . $val . "'";
$rs = mysql_query($sql);
while($row = mysql_fetch_array($rs))
{
   echo('Address: ' . $row['store_address']);
   echo('Phone: ' . $row['store_phone']);
}
