MySQL/PHP Variable Question

OK, I'm making my own Itemshop. But I'm not the best coder around and need some help with something simple.

I need multiple things to show up from the same MySQL table column. For example, here's a part of my file:

Code:

// select information

$shop_id     = $DB_site->query("SELECT shop_id FROM itemshops");

$shop_name   = $DB_site->query("SELECT shop_name FROM itemshops");

$shop_image  = $DB_site->query("SELECT shop_image FROM itemshops");

$shop_rating = $DB_site->query("SELECT shop_rating FROM itemshops");

$shop_profit = $DB_site->query("SELECT shop_profit FROM itemshops");

$shop_total  = $DB_site->query("SELECT shop_total FROM itemshops");

Now, if I have, for example, 3 Itemshops, how would I get the three Itemshop's attributes to show? Use the variables three times? :ermm:

Thanks.

here try this

PHP Code:


		
			
$shops = $DB_site->query("SELECT * FROM itemshops DESC LIMIT 3");

while ($shop = $DB_site->fetch_array($shops)) {

        $i = 1;

        $shop_id$i = $shop[shop_id];

        $shop_name$i = $shop[shop_name];

        $shop_image$i = $shop[shop_image];

        $shop_rating$i = $shop[shop_rating];

        $shop_profit$i = $shop[shop_profit];

        $shop_total$i = $shop[shop_total];

        $i++;

}

that will select the first 3 rows from your database and put each variable into for example

$shop_id1 will be the first shops id
and
$shop_total2 will be the second shops total

im pretty sure this should work

So then for the other Itemshops I'd just simply repeat that except change the value of $i to 2?

Or am I getting this wrong? :p

EDIT: Or change DESC LIMIT to 4 or above to include extra Itemshops?

OK, this is me testing your method.

PHP Code:


		
			
<?php



require("./global.php");



$shops = $DB_site->query("SELECT * FROM itemshops DESC LIMIT 3");

while ($shop = $DB_site->fetch_array($shops)) {

        $i = 1;

        $shop_id$i = $shop[shop_id];

        $shop_name$i = $shop[shop_name];

        $shop_image$i = $shop[shop_image];

        $shop_rating$i = $shop[shop_rating];

        $shop_profit$i = $shop[shop_profit];

        $shop_total$i = $shop[shop_total];

        $i++;

}

?>

<html>

<head>

</head>

<body>

$shop_name2</body></html>

But I get an error:

PHP Code:


		
			
Parse error: parse error, unexpected T_VARIABLE in /home/virtual/site139/fst/home/staticnetwork/public_html/forum/test.php on line 8

:(:( Any ideas? Gurus? ;)

mr e	02-01-2003 04:22 PM

do this for all of them

PHP Code:


		
			
$shop_id[$i]

i think that should work

Hmmm... Well Here's my full file:

PHP Code:


		
			
<?php



require("./global.php");



$shops = $DB_site->query("SELECT * FROM itemshops"); 

while ($shop = $DB_site->fetch_array($shops)) { 

$i = 1; 

$shop_id[$i] = $shop[shop_id]; 

$shop_name[$i] = $shop[shop_name]; 

$shop_image[$i] = $shop[shop_image]; 

$shop_rating[$i] = $shop[shop_rating]; 

$shop_profit[$i] = $shop[shop_profit]; 

$shop_total[$i] = $shop[shop_total]; 

$i++; 

}

?>

<html>

<head>

</head>

<body>

<?php

echo "$shop_id[$i]";

?>

</body></html>

But it just doesn't show anything at all when I load up the page... :(

Anyone? This is really bugging me and I need answers fast. ;) Gotta finish this by the date... :(

you can't echo $shop_id[$i], it has to be $shop_id[0] or [1] etc, but are you going to use these variables in repeating rows or at all different parts of the page? like are you going to use $shop_id[0] at one part and $shop_id[1] in some completely different part?

It's be like:

Code:

<tr>

 <td>

  $shop_id[0]

 </td>

</tr>

<tr>

 <td>

  $shop_id[1]

 </td>

</tr>

So they're not that far away. What's the diffrence anyway?

mr e	02-03-2003 09:16 PM

because if your going to do this in repeating rows there is a much easier way, this way lets you use these variables anywhere you want, if you want to do repeating rows, ex:
$shopid1, $shopname1 etc
$shopid2, $shopname2 etc

then do

PHP Code:


		
			
$shops = $DB_site->query("SELECT * FROM itemshops DESC LIMIT 3");

while ($shop = $DB_site->fetch_array($shops)) {

     print "<tr><td>$shop[shop_id]</td><td>$shop[shop_name]</td></tr>"

}

this will print table rows with the shop id and shop name in the td's until the DESC LIMIT is reached or the end of your db

All times are GMT. The time now is 07:24 AM.
