Problems using dynamenu with large databases
I am testing dynamenu with product contributions.. running into a major problem
dynamenu works great without the product contribution, the problem is with the product cont the file is too big and will only display the main categories not any drop downs (I don't know why)
The issue is when the navigation bar generating text is too big
$output which is passed to the main program in the code
$categories_string = tep_make_cat_dmlist();
is where the text is generated
the information is created correctly (I can print it out) but when the output is more than 230441 characters (yes that is the exact number) the navigation bar wont show ANY drop downs even though the information is in correct form..
There is not an error in the bigger file being created correctly, when i truncate the length to 230441 characters it outputs fine (but incomplete because I have cut off some data)
Any idea if the error is fixable in code, if some server side setting can be altered or what?
I believe the meat of code where the information is getting dropped is
$mid->setMenuStructureString($categories_string);
$mid->parseStructureForMenu('catmenu');
switch ($menu_type) {
case 0: // Horizontal drop-down
$mid->setDownArrowImg($menu_downarrowimg);
$mid->setForwardArrowImg($menu_fwdarrowimg);
$mid->setHorizontalMenuTpl('layersmenu-horizontal_menu.ihtml');
$mid->setSubMenuTpl('layersmenu-horiz_sub_menu.ihtml');
$mid->newHorizontalMenu('catmenu');
$mid->printHeader();
$categories_menu = $mid->getMenu('catmenu');
$GLOBALS['dmfooter'] = $mid->getFooter();
Thanks in advance for any clues
