 |
|
How does the Pager extraVars work?
My real question: How do I keep my URL parameters after the "items per page" select form has been submitted. Selecting a different number of items per page clears the URL parameters and I get all the results in my database! (very nicely paginated, however!)
This page:
http://pear.php.net/manual/en/package.html.pager.intro.php
instructs me to use extraVars, so this is what I tried:
| Code: | $params = array(
'itemData' => $ALL_DATA ,
'perPage' => 10,
'delta' => 5,
'append' => true,
'clearIfVoid' => true,
'urlVar' => 'entrant',
'useSessions' => true,
'closeSession' => true,
'mode' => 'Sliding',
'extraVars' => array(
'userTerm' => $_GET['userTerm'],
'term' => $_GET['term'],
),
); |
I looked around in the HtmlWidgets.php file, where the getPageSelectBox function is defined, but nothing I did there made any difference.
Thanks for any ideas. |

| Just a guess: Are you sure that the GET protocol is used? If it isn't, the values of $_GET[...] will be empty ... |

Yes, I know the GET protocol is used.
After staring at the URL produced from extraVars parameter I'm pretty sure that's not my solution. extraVars puts the parameter in the URL produced for the links to each page of pagination.
What I need is 1 specific GET parameter to go into the "items per page" URL and despite my adding this code to the form:
| Code: | | <form action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']). '?userTerm='. htmlspecialchars($_GET['userTerm']); ?>" method="GET"> |
the parameter seems to get stripped away by the function that controls the form's action (the HtmlWidgets.php file, I believe). So I guess I'll go back to that function and mess around.
My php abilities are limited to copy and adapt. If anyone has modified the HtmlWidgets.php file I would love to hear about it.
Thanks. |
