Updating part of CMS

[j05hr]

I can upload things into my database from the website.  I'm having trouble getting the edit feature to work.

 

My code...

 

This is where it's meant to echo back what you've clicked on to edit.

<input type="text" name="menu_name" value="<?php echo $sel_subject['menu_name']; ?>" id="menu_name" />

 

But nothing happens,

 

Here are the functions

function find_selected_page () {
	global $sel_subject;
	global $sel_page;
	if (isset($_GET['subj'])) {
		$sel_subject = get_subject_by_id($_GET['subj']);
		$sel_page = NULL;
	} elseif (isset($_GET['page'])) {
		$sel_subject = NULL;
		$sel_page = get_page_by_id($_GET['page']);
	} else {
		$sel_subject = NULL;
		$sel_page = NULL;
	}
}


function navigation($sel_subject = null, $sel_page = null) {  
	$subject_set = get_all_subjects();
	// 5. Use returned data
	while ($subject = mysql_fetch_array($subject_set)) { 

	echo "<div class=\"menu-name\">";  echo "<a href=\"edit_subject.php?page=" . urlencode($subject["id"]) .
		"\">{$subject["menu_name"]}</a>";  echo"</div>";
	echo "<div class=\"buying-text\">";  echo "{$subject["content"]}";  echo"</div>";

	echo "<div class=\"image\">"; echo"</div>";

	}
}

 

That's all the code I think it uses but if you need any more let me know.

 

Thanks,

Josh
