значи този код ми извича всички записи от базата
как може да стане до извлича данните от определена категория
ето и базата
самите категорий се записват в друга таблица
Код:
<?
$connection = mysql_connect("localhost","dbusername","dbpassword")
or die("no connect");
mysql_select_db("dbname");
if(!isset($_GET['page'])){
$page = 1;
} else {
$page = $_GET['page'];
}
// Define the number of results per page
$max_results = 5;
// Figure out the limit for the query based
// on the current page number.
$from = (($page * $max_results) - $max_results);
// Perform MySQL query on only the current page number's results
$sql = mysql_query("SELECT * FROM articles LIMIT $from, $max_results");
while (list ($id , $title,$text, )=mysql_fetch_array ($sql)) {
$text_limit="$text";
$text_limit=substr($text,0 , 50);
echo "<p><a href=procheti.php?id=$id>$title</a></p>$text_limit";
}
// Figure out the total number of results in DB:
$total_results = mysql_result(mysql_query("SELECT COUNT(*) as Num FROM articles"),0);
// Figure out the total number of pages. Always round up using ceil()
$total_pages = ceil($total_results / $max_results);
// Build Page Number Hyperlinks
echo "<center><p><br />";
// Build Previous Link
if($page > 1){
$prev = ($page - 1);
echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$prev\"><<Previous</a> ";
}
for($i = 1; $i <= $total_pages; $i++){
if(($page) == $i){
echo "$i ";
} else {
echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$i\">$i</a> ";
}
}
// Build Next Link
if($page < $total_pages){
$next = ($page + 1);
echo "<a href=\"".$_SERVER['PHP_SELF']."?page=$next\">íàïðåä>></a>";
}
echo "</p></center>";
?>
ето и базата
Код:
CREATE TABLE articles (
id INT PRIMARY KEY AUTO_INCREMENT,
title VARCHAR(100) DEFAULT NULL,
text TEXT,
category INT(8) NOT NULL DEFAULT '0',
);
