PHP/MySQL Select and Display Result While Array AND integer increment

Recommended Posts

Hi, I have come up with the following code, I need it to get the details of several scattered products and echo the results, the trick is I don't want it to echo the results one after the other... I want to have the products scattered between unique text on the page but don't want to run the query several times for performance reasons.

 

E.g.- PAGE to look like this:

 

$Product_1

 

unique text/images

 

$Product_2

$Product_3

 

unique text/images

 

$Product_4

 

 

Current Code:

 

<?
$result = mysql_query("SELECT * FROM products where Product_ID IN (475, 465, 234, 567, 845)");
while($row = mysql_fetch_array($result))
  {
    $x = "1";
      while ($x<=3)
{
          echo $x;
          $Product = "Product_";
          $Product = $Product.$x;
          echo $Product;
          $Product = $row['Product_ID'];
          echo $Product;
          $x++; 
          echo $x;
        }
  }

 

 

At the moment it returns the following results:

 

1

Product_1

465

2

 

2

Product_2

465

3

 

3

Product_3

465

4

 

1

Product_1

475

2

 

2

Product_2

475

3

 

3

Product_3

475

4

A few problems...

 

In Blue... it duplicates for product 465

In Red... It repeats again for 475

Also.... it starts with 465, but I want it to go in order as how it appears - $result = mysql_query("SELECT * FROM products where Product_ID IN (475, 465, 234, 567, 845)");  so should start with 475

 

 

I want to get the following result:

 

1

Product_1

475

2

 

2

Product_2

465

3

 

3

Product_3

234

4

 

4

Product_4

567

4

 

(and so on.....)

 

 

If anyone could provide me assistance with my troubled 'while loop' statement that would be much appreciated!  :D

Hey Zane, (leave it in PHP for now... the order is only a minor problem).

 

Yes it isn't very logical and I am sure there is a better way! I'm struggling to work out how to get X to increment for each product so I can give each product a unique ID. 

 

I originally started with this, which didn't work as it displayed them one after the other - I could not scatter them on the page:

 

while($row = mysql_fetch_array($result))
  {
  echo $row['Product_ID'];
  echo "<br />";
  }

 

It returned:

 

465

475

234

 

 

I progressed to this, which didn't work because X does not increment, and cannot assign a unique reference to each result:

 

while($row = mysql_fetch_array($result))
  {
    $x = "1";
    echo $x;
    $Product = "Product_";
    $Product = $Product.$x;
    echo $Product;
    $Product = $row['Product_ID'];
    echo $Product;
    $x++; 
    echo $x;
   }

 

Which returned:

 

1

Product_1

465

2

 

1

Product_1

475

2

 

1

Product_1

234

2

Ok, I have worked out, X=1 had to be 'outside' the loop (duh):

 

<?
$result = mysql_query("SELECT * FROM products where Product_ID IN (475, 465, 234, 567, 845)");

$x = "1";

while($row = mysql_fetch_array($result))
  {
    $Product = "Product_";
    $Product = $Product.$x;
    echo $Product;
    $Product = $row['Product_ID'];
    echo $Product;
    $x++; 
  }
?>

 

It returns:

 

Product_1

475

Product_2

465

Product_3

234

 

(and so on..)

 

But, after all that later on in the page I have:

 

<?
echo "$Product_1";
?>
Text text text
<?
echo "$Product_2";
?>

 

I would expect:

 

475

Text text text

465

 

But get:

 

 

Text text text

 

 

It's not working... maybe I am doing it wrong, how do I call a specific product from the  $result  query?

 

e.g.

 

"get and echo Product ID, Product Name, Product Price from $result where ID = 475"

Worked the next bit out...

 

$result = mysql_query("SELECT * FROM products where Product_ID IN (475, 465, 234, 567, 845, 22)");
$x = "1";
while($row = mysql_fetch_array($result))
  {
  	  echo "$x";
  	  echo "<br />";
if ($x==1) $one = $row['Product_ID'];
if ($x==2) $two = $row['Product_ID'];
if ($x==3) $three = $row['Product_ID'];
if ($x==4) $four = $row['Product_ID'];
if ($x==5) $five = $row['Product_ID'];
    $x++; 
  }

  	echo $one;
  echo "<br />";
  	echo $two;
  echo "<br />";
  	echo $three;
  echo "<br />";
  	  	echo $four;
  echo "<br />";
  	  	echo $five;

 

gave desired result:

 

1

2

3

4

5

22

234

465

475

845

 

Now onto the order.... Can this be moved to sql please?

 

I have the statement:

 

SELECT * FROM products where Product_ID IN (475, 465, 234, 567, 845, 22)

 

and when I run this:

 

while($row = mysql_fetch_array($result))

 

It sorts them then displays them automatically ascending...

 

22

234

465

475

845

 

How can I get it to display them in the order I have entered them? e.g.:

 

475

465

234

567

845

22
