Hyperlink in PHP to MySQL record

[jodyanne]

Hello,

 

I am having trouble as i am new to php. I have connected to the database and I have displayed the fields i want on my page. I need to access certain fields by links to each letter.

 

For example A will link to the products starting with A and so on.

 

I am using PHP ad MySQL. The database is however on a different server. I only have the .php file at the moment and want to display the data on a HTML page.

 

I am just unsure of how to make a link to the product field and the price field and display them within a table.

My code is this so far..

 

<?php

// Connect to the database server

mysql_connect("host", "username", "psssword") or die(mysql_error());

 

// Open to the database

mysql_select_db("telephon_cscartrestore") or die(mysql_error());

 

//select records from table

$result = mysql_query("SELECT cscart_product_descriptions.product, cscart_product_prices.price FROM cscart_product_descriptions, cscart_product_prices ORDER BY cscart_product_descriptions.product ASC") or die(mysql_error());

 

echo "<table border='1'>";

echo "<tr> <th>Product</th> <th>Price</th> </tr>";

// keeps getting the next row until there are no more to get

while($row = mysql_fetch_array( $result )) {

// Print out the contents of each row into a table

echo "<tr><td>";

echo $row['product'];

echo "</td><td>";

echo $row['price'];

echo "</td></tr>";

}

 

echo "</table>";

 

?>

I want a link 'A' that opens all records starting in A and so on. Is this possible?

 

thanks in advance

Yes, it is possible. The best way is to store the letter in an extra field, put an index on it and simply add an extra condition:

 

 AND `letter` = 'A'

 

If you can't do it for some reason, then you must use LIKE clause:

 

 AND `title` LIKE 'A%'

 

Anyway, for performance reasons, you really should an index to the title field, too.

I'll disagree that this is the best way

I agree. Using a function like LEFT() would be faster than LIKE. For example:

 

where left(field_name, 1) = 'A'
