hello.
thanks wrox for the excellent book (beginning php5) and this forum.
So here his my question about a function paginate (chapter 16) that i'm trying to put with the tumbnail gallery (chapter 7).
After some trials i don't still be able to put it all together. Some advices from you fellas would be precious to understand the paginate() function.
gallery.php
quote:
<?php
require_once 'functions.php';
$page = 1;
$limit = 4;
$start = ($page - 1) * $limit;
//connect to the database
$link = mysql_connect("localhost", "root", "password")
or die("Could not connect: " . msql_error());
mysql_select_db("dados", $link)
or die (mysql_error());
$ImageDir = "images/";
$ImageThumb = $ImageDir . "thumbs/";
?>
<html>
<head>
<title>Welcome to our Photo Gallery</title>

<body>
<p align="center">Click on any image to see it full sized.</p>
<table align="center">
<tr>
<td align="center">Image</td>
<td align="center">Caption</td>
<td align="center">Uploaded By</td>
<td align="center">Date Uploaded</td>
</tr>
<?php
//get the thumbs
$sql = "SELECT SQL_CALC_FOUND_ROWS " .
"$ImageDir, " .
"$image_id, " .
"$ImageThumb, " .
"$image_caption, " .
"$image_description, " .
"$image_date, " .
"FROM images " .
"LIMIT $start, $limit";
$getpic = mysql_query($sql)
or die(mysql_error() . $sql);
$pagelinks = paginate($limit);
//$getpic = mysql_query("SELECT * FROM images")
// or die(mysql_error());
while ($rows = mysql_fetch_array($getpic)) {
extract($rows);
echo "<tr>\n";
echo "<td><a href=\"".$ImageDir . $image_id . ".jpg\">";
echo "<img src=\"" . $ImageThumb . $image_id . ".jpg\" border=\"0\">";

echo paginate();

Erreur de syntaxe
près de ' , images/thumbs/, , , , FROM images LIMIT 0, 4' à la ligne 1SELECT SQL_CALC_FOUND_ROWS images/, , images/thumbs/, , , , FROM images LIMIT 0, 4

i've tried also a simple query "SELECT * FROM images LIMIT $page, $limit"
quote:
<?php
require_once 'functions.php';
$page = 1;
$limit = 4;
$start = ($page - 1) * $limit;
//$start = ($page - 1) * $admin['pageLimit']['value'];
//connect to the database
$link = mysql_connect("localhost", "root", "password")
or die("Could not connect: " . msql_error());
mysql_select_db("dados", $link)
or die (mysql_error());
$ImageDir = "images/";
$ImageThumb = $ImageDir . "thumbs/";
?>
.......
........
<?php
//get the thumbs
$getpic = mysql_query("SELECT * FROM images LIMIT $page, $limit")
or die(mysql_error());
while ($rows = mysql_fetch_array($getpic)) {
extract($rows);
echo "<tr>\n";
echo "<td><a href=\"".$ImageDir . $image_id . ".jpg\">";
echo "<img src=\"" . $ImageThumb . $image_id . ".jpg\" border=\"0\">";
echo "</a></td>\n";
echo "<td>" . $image_caption . "</td>\n";
echo "<td>" . $image_description . "</td>\n";
echo "<td>" . $image_date . "</td>\n";
echo "</tr>\n";
}
echo paginate();
?>
