Building a html table from the database?

Hello,

I wondered if anyone could advise, I am trying to write some php code to access the data from the products table, and then display these products as 4 per row in the html table.

For example if there were 4 products there would be 1 html table row displaying the 4, and 10 products 3 rows.

I am not quite sure where to start with the display. I wondered anyone would be-able to offer any guidance to writing this type of nested loop?

Thank you

<?php
$Sproducts = "SELECT title, price, description, small_image, large_image FROM products";
$Srproducts = mysql_query($Sproducts);
                     
if($Srproducts && mysql_num_rows($Srproducts) > 0) {                                                    
?>        

<?php  
     while ($rproducts = mysql_fetch_assoc($Srproducts)) {                            
?>

<?php              
     }
}

?>

The html table looks like this:

<br />
<table border="0">
<tr>
<td><img src="1.jpg" /></td>
<td><img src="2.jpg" /></td>
<td><img src="3.jpg" /></td>
<td><img src="4.jpg" /></td>
</tr>
<tr>
<td><img src="5.jpg" /></td>
<td><img src="6.jpg" /></td>
<td><img src="7.jpg" /></td>
<td><img src="8.jpg" /></td>
</tr>
<tr>
<td><img src="9.jpg" /></td>
<td><img src="10.jpg" /></td>
</tr>
</table>


The PHP code that generates the html above forces the table to wrap at 4 columns.


$results = mysql_query($sql) or die ('problem with db query' . mysql_error());

echo "<table border=\"0\">\n";
echo "<tr>\n";

$rowcnt = mysql_num_rows($results);
$row = 0;
$col = 0;

for($u=0;$u<$rowcnt;$u++) {

$col = $col + 1;

$ProdPic=mysql_result($results,$u,'ProdPic');
$ProdTitle=mysql_result($results,$u,'ProdTitle');

// start new row
if($col > 4) {
 $row = row + 1;
 $col = 1;
 echo "</tr>\n";
 echo "<tr>\n";
}


echo "<td><img src=\"$ProdPic\" /></td>\n";

}

echo "</tr>\n";
echo "</table>\n";

Thank you, I will try the code with my database.

I was hoping to display the name and price of the product under each photo. Would adding another two rows under the image be simple to add to the existing loop?

I think you are looking for something like this?

<table border="1">
<tr>
<td><img src="1.jpg" /></td>
<td><img src="2.jpg" /></td>
<td><img src="3.jpg" /></td>
<td><img src="4.jpg" /></td>
</tr>
<tr align="center">
<td>one $1</td>
<td>two $2</td>
<td>three $3</td>
<td>four $4</td>
</tr>
<tr>
<td><img src="5.jpg" /></td>
<td><img src="6.jpg" /></td>
<td><img src="7.jpg" /></td>
<td><img src="8.jpg" /></td>
</tr>
<tr align="center">
<td>five $5</td>
<td>six $6</td>
<td>seven $7</td>
<td>eight $8</td>
</tr>
</table>

I'll build the PHP to create this later.

Could I ask if the code would be posted here, or on the site below?

Take a look at this.  It may be a bit messy but it appears to work.  

You should get the general idea.
