php & query string variables in a url
I've been scratching my head for a couple days now. What I'm
trying to do seems soooooo easy but it doesn't work. Maybe someone
can spot my problem in the code.
What I'm doing is breaking a single blob mysql field into multiple "pages" by inserting a code snippet into the field. That part works fine. The url for the page in question with a sample article is
http://208.106.143.80/articles/articles.php?idq=141&cat=4&pg=1
The url contains the article id, article category and page number. At the bottom of the page is the pagination that reloads the page with another "page" of the article. The code for that is:
$totalpages = $total;
if ($totalpages > 1) {
echo "<p style='text-align:right;'><strong>Page:</strong> ";
if ($i > 1) {
echo " <a href='".$_SERVER['PHP_SELF']."?pg=".($i-1)."'><< Prev</a> ";
}
for ($x = 1; $x <= $totalpages; $x++) {
if ($x == $i) {
echo "<strong>[".$x."]</strong> ";
}
else {
echo "<strong><a href='".$_SERVER['PHP_SELF']."?pg=".$x."'>".$x."</a></strong> ";
}
}
if ($i < $total) {
echo " <a href='".$_SERVER['PHP_SELF']."?pg=".$k."'>Next >></a></p>";
}
}
Basically all I'm doing is throwing the new querystring pg=$x to the end of the current page url and reloading the current page. And that is the problem. Even though the page links look right in the browser, it just keeps loading the same "page" over and over again. I can go into the url in the browser and manually change from page 1 to page 2, etc. and that works as it should.
Ideas from anyone smarter than I?
