I am not a php expert so maybe my question is trivial<\/p>\n
I have a page links.php with two iframes (left and right).<\/p>\n
left lists Link sections after a query from db, right should list all links from a section after section has been selected by click.<\/p>\n
the result – section’s names [Section] is displayed in left frame and a number for each row [Sectionid] has been requested,to<\/p>\n
If I perform for test<\/p>\n
echo $row['Sectionid'];\n echo $row['Section'];\n<\/code><\/pre>\nI get correctly both values for each row and of course the name of the section [Section] displays correctly.<\/p>\n
now I want to post the request to right frame, where I need $Sectionid; for the query in the link table.<\/p>\n
First I did the following:<\/p>\n
echo'' ;\n echo ''.$row['Section'].'<\/b>';\n echo \"\"; \n echo '';\n<\/code><\/pre>\nThis will show the content in the right frame as desired, but it displays a button with the section number in the left frame. Not exactly what I want. I would like to display the Section list on the left as links on the menu names to be selected. So I tried the following;<\/p>\n
\n<\/code><\/pre>\nWhile in this case the section names are indeed displayed as links, when I click on one of these links it does not behave as desired.<\/p>\n
First I get an answer in the same frame (the one that lists the Sections), so target is ignored<\/p>\n
Second the value for Sectionid is not posted to linkcontent.php, as I get the errormessage:<\/p>\n
Notice: Undefined index: Sectionid in \/usr\/share...\n<\/code><\/pre>\nSimply it does not work.<\/p>\n
How can I make perform php the action in order to obtain the result in the second frame as with the form command?<\/p>\n
A minor question: when I first call link.php both frames listmenu.php and linkcontent.php of course are displayed, but right frame displays<\/p>\n
Notice: Undefined index: Sectionid in \/usr\/share... \n<\/code><\/pre>\nas it did not receive any value, of course. While it is obvious that it cannot receive any value before a Section has been selected, I would like to suppress this message with some function telling not to expect a value for Sessionid if value for Sessionid is empty in order to have the page blank before any selection in the menu list.<\/p>\n
