    <p>i've been trying to wrap my head around this for a while now, doing research online yielded nothing. Basically i have a 5 column table representing a tree structure. You could think of it as a directory list. Im trying to build a unordered list menu out of this.</p> <p>This is the MYSQL table:</p> <hr> <p><strong>Parent/Child/Grandchild/Grand-grandchild/grand-grand-grandchild</strong></p> <p>France/Aquitaine/Dordogne/Bergerac/Issac</p> <p>France/Aquitaine/Dordogne/Nontron/Nontron</p> <p>Cyprus/Paphos/Paphos District/Coral Bay/Coral Bay</p> <p>Denmark/South Denmark/Langeland/Rudkobing/Langeland</p> <p>Egypt/Sinai Peninsula/Red Sea/Sharm El Sheikh/Sharm El Sheikh</p> <hr> <p>The unordered list should look like this:</p> <ul> <li>France <ul> <li>Aquitaine <ul> <li>Dordogne <ul> <li>Bergerac <ul> <li>Isaac</li> </ul> </li> <li>Nontron <ul> <li>Nontron</li> </ul> </li> </ul> </li> </ul> </li> </ul> </li> <li>Cyprus <ul> <li>Paphos <ul> <li>Paphos District <ul> <li>Coral Bay <ul> <li>Coral Bay</li> </ul> </li> </ul> </li> </ul> </li> </ul> </li> </ul> <p>etc...</p> <p>Basically producing an unordered list menu representing all five levels, grouping everything correctly.</p> <p>I have been toying with the following function to try and get what i want: <a href="http://kevin.vanzonneveld.net/techblog/article/convert_anything_to_tree_structures_in_php/" rel="nofollow">http://kevin.vanzonneveld.net/techblog/article/convert_anything_to_tree_structures_in_php/</a></p> <p>could anyone provide any further info on how to solve this? I attempted to build loops for each level but quickly found out this to be futile, and that recursive functions should be used.</p>

    2. COmmm, problem is I am working with a 5 column table rather than hierarchial data in adjacent/nested model, so it is impossible to change the structure to this and use code examples online. Would reorganising this 5 column table into a multidimensional array, and then using recursion be the answer? Could someone post any code examples please?

    3. COPlease provide the CREATE TABLE statement for the table, along with some sample INSERTS for data if possible.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
