Question

I have one page which is divided into sections. Ιn each section I like to load a page. If I have a form and I click submit button or a link I like to show the results in this section.

For example: I am in section “item1_section2” which show the php page manage_team_teacher.php. In page manage_team_teacher.php I have a form, if I submit the form or click a link I like to show the results again in section “item1_section2”. I am very confused on how to carry this out because all is in the same page (index.php). I’m new in PHP and I need your help. what do you suggest?

As you can see I try a lot of methods but I have problems: I try to GET from URL the name of page (in category).

<a href="index.php?category=manage_team_teacher2.php&amp;id_team=<?= $row['id_team']; ?>#item1_section2">manage</a></td>

above is an example of a link I tried to create

<div class="content" style="font-size:30px;">
                    <div class="section black" id="item1_section1" style="float: left; overflow: scroll; padding: 30px 0 0 30px; width: 869px;">
                            <h2>Section 1</h2>
                            <p>
                            sdffffffffffffffffffffffffff
                            sdffffff
                            sdf 
                            </p>
                            <ul class="nav">

Answer 1

you need to also check that url is present

if(isset($_GET['category']) $$ $_GET['category'] ==bla ){

other wise if anybody set bla in url and it is not present than it causes

Warning: include(): Failed opening '' for inclusion (include_path='blabal') on line bla
